Scope

The invention relates to optical devices for use in vehicles.

Prior art

Currently in automobiles and other vehicles used a system of mirrors consisting of the interior rear view mirrors and two exterior side mirrors. This standard system has several disadvantages. One of them is the presence of areas that are not visible by the driver. Another disadvantage is the fragmentation of the image right, left and rear spaces surrounding the driver. At each switching glance, the driver receives only a partial, and therefore, incomplete information, which can create dangerous situations on the roads. The system does not work when the twists and turns of the vehicle.

To ensure traffic safety, ceteris paribus, the driver needs continuous full information about the rapidly changing environment around a moving car.

This topic is dedicated numerous patent development.

Known system of external video cameras (for example, patents DE 4228794 A1 from 29.08.1992, EN 2096202 C1 from 26.08.96) or systems that use fiber optics that carry information on the windshield or on the dashboard, but these expensive and is egco damaged system have not yet found wide application. They are easy to sweat, become clogged with road dirt, dust, snow, lose sensitivity for some time under the action of the direct light of the headlights.

Known patents, in which the image from the outer side of the mirror is transferred to the cabin, bringing the image side space to the driver (for example, patents DE 3335981 C2, 20.10.88; DE 4235744 A1, 23.10.92; EN 2127201 C1, 03.04.95 g; RF 2820097 A1, 30.01.01; EP 0891267 B1, 25.04.97). A significant drawback of these complex optical systems is the need to install exterior side mirror at an acute angle to the longitudinal axis of the machine. In this situation mirrors greatly reduced area side view and enlarged blind dead zone.

In PCT application WO 2004/054845 A1, published 01.07.2004, offers installation on the ceiling of the cab of a set of mirrors that reflect the image space from the outer side mirrors and rear view mirrors on mirrors that are installed on the control panel, on the side of the driver. However, this proposal has a number of drawbacks. First, remain the same "dead" zones, which are not visible by the driver, as in the traditional system of mirrors. Secondly, the location of the reflecting mirrors on the ceiling of the cabin near the head of the driver is hazardous and requires a maximum reduction of the amount of mirrors that will reflect on the quality of views of the constituent driver image. Thirdly, on the mirror that the driver sees, creates three rows of multiple paintings anterolateral, posterolateral and posterior spaces that are not related to each other. This multiplicity of information, of course, makes it difficult to adequately perceive and tires the driver. Therefore, the author proposes to use a special curtains covering part of the obtained image (anterolateral space), which complicates the device. But posterolateral and posterior space is also projected separately, without creating a single picture of the panorama.

In a number of patents rearview mirror is located above the cab and through the mirror image of the rear space is transmitted to the interior rear view mirror, located at the upper edge of the windshield. So in the patent US-A-3774996 describes a periscopic device in the anterior roof of the vehicle, consisting of three mirrors, at least one of which is located inside the car is the rear view mirror at the upper edge of the windshield. In the patent EP No. 0608385 B1 from 23.10.1992, the image with the upper exterior mirror is also transmitted to the rear view mirror at the upper edge of the windshield, but through the windshield. In the patent DE No. 882043 from 08.07.1949, the image is transmitted from the upper exterior mirror on the mirror u n the life of the edge of the windshield, outside it. In this embodiment, the outer position of the lower mirror on the hood of the car makes it difficult to adjust it, put in the difficult conditions of weather and partially obscure the view on the near space in front of the machine.

In the patent US 3947096 dated March 30, 1976, are encouraged to use the open top hatch on the inner surface of which is located the rear view mirror. Provides an immediate overview of this mirror driver, which is extremely inconvenient, since it is necessary to reject his head backwards.

In the patent RU 2286267 C2 from 09.11.2004, describes the various options for the location of the exterior mirrors to obtain a panoramic image posterolateral spaces at the front of the mirror, located in sight of the driver. In the system were first introduced to the inner side mirrors. The proposed system proved to be fairly difficult to perform and adjust numerous mirrors. In addition, the location of the front panoramic mirrors constantly in sight of the driver resulted in rapid fatigue of the driver. Especially tiring when driving in the narrow streets of the rapid flashing of the side spaces, reflected in the internal side mirrors.

This patent may be adopted as the prototype of this proposal.

The purpose of the invention is the improvement of road safety in the POPs the project conditions to obtain driver full information about the situation around the vehicle.

Disclosure of the invention

For a complete panorama of space around the vehicle and the elimination of "dead" zones serves to position the upper part of the system of mirrors above the upper level of the roof of the vehicle. For the best experience, you are encouraged to separate the image of the anterior and anterolateral spaces from the image back and posterolateral spaces.

When the location of the top of the mirror system above the roof level there are two available options - interior and exterior location of the top of the mirrors. In the first embodiment, in the front section of the roof creates a wide enough through hole, closed on top by a transparent dome. In the space under the dome above the level of the rest of the roof is located in the upper part of the mirror system. In this case, the upper mirror is actually located in the upper section of the cabin, become interior with all relevant benefits (not sweat, do not freeze, do not become dirty easily adjusted). Clear dome, located on the rooftop, less prone to contamination than lower bodywork, and heated air in the cabin or has additional heating and ventilation. In the upper section of the dome can be covered with a sun shade.

In the second embodiment, the upper part of the mirror system, R is polojennaya above the roof level, is outer. The exterior of the upper mirror can be placed on the windshield or on the roof of the vehicle and send an image of the surrounding space through the windshield, through the transparent part of the roof through the open sunroof or through the rear window of the car. From above they must be closed by a transparent case with heating for protection from the weather and the sun visor.

Above the windshield it is possible to have a system of mirrors for far anterior and anterolateral panoramas. The image with the top mirror is reflected through the windshield on the panoramic mirror on the instrument panel, visible by the driver. The need for this system occurs only at certain moments, when, for example, need to consider the space ahead and to the side from the front of a moving vehicle to prepare for the rebuilding, turning or overtaking. Therefore it is better this panorama is located in the side of the field of view of the driver or when placed in a field of view of the driver to allow the driver to close and open it only when necessary. This will reduce the fatigue of the driver, but will complicate the design.

Above the windshield is also possible to arrange the upper part of the mirror system for posterior and posterolateral from the driver's space. These mirrors can be seen by the driver directly or from the expressions can be passed through an additional mirror on the panoramic mirror on the instrument panel, visible by the driver.

When placed above the roof, as already mentioned above, the image can be transmitted at lower panoramic mirror visible to the driver through the transparent part of the roof through the open sunroof or through the rear window.

The upper part of the mirror system, at least, may consist of three flat mirrors, one for the front or rear of the space and two lateral spaces. It is possible to use a significantly larger number of mirrors, or replace a flat mirror on a spherical or aspherical mirror. It is possible to use a conical mirror or other mirror system, which can provide a display of the panorama without distortion greater than 180 degrees. Circular panorama is perceived as extremely difficult, requires special training. Therefore, mirrors, visible by the driver, must be reflected from the upper mirror separately anterior and anterolateral and posterior and posterolateral space.

When the location of the upper mirror above the roof of the vehicle for posterolateral panorama necessary additional mirrors reflecting the image from the top of the mirrors on the bottom panoramic mirror available the view of the driver. This system additional mirrors may be located below, above or to the side of the upper mirror. One option is to locate the additional money is calories in one unit with the upper mirrors (top, bottom or side of them). This will reduce the size of the mirrors.

At relatively high location of the upper part of the system of mirrors on windshield or on the roof is achieved review the full panorama of space around the vehicle without the "dead" zones. In this case, there is no need in the exterior side mirrors, increasing the dimensions of the vehicle. Also, there is no need (except one) in the back window of the cab, which is very important for special transport.

The BEST OPTIONS INVENTIONS

Locations of the upper part of the mirror system of the vehicle slightly.

The best option is a special wide enough hole in the front section of the roof, above which is hermetically installed transparent dome. Under the dome, above the roof level, is located in the upper part of the mirror system to the surrounding spaces. In this case, the upper mirror are interior.

Another option is the location of the upper part of the system of mirrors on windshield. This gives you the opportunity to reflect the image directly on the dashboard.

For far ahead of the anterior and anterolateral spaces of the upper mirror can be raised high enough to see the space in the circle in front of the transport. The lower part of the mirror system for anterolateral review is better positioned parallel to the top, as in this case, the driver sees a direct mirror image.

The upper mirror to browse back and posterolateral spaces may also be located above the windshield in the same block with anterior and anterolateral mirrors or separately from them. They can be seen by the driver directly or transfer the image on the bottom panoramic mirror visible to the driver through an additional mirrors.

Another option for a full review of the posterior and posterolateral spaces - location of the upper mirror above the roof of the vehicle.

The upper mirror can be placed in any part of the roof. The closer to the front Department of the roof mirrors are, the more browse the lateral spaces. The upper mirror can be in a streamlined case with a transparent part for a full overview of the surrounding spaces and the free transfer of the image and the lower part of the mirror system. Over the holder is inserted in the shield for protection from sun and rain. In case there is a system of ventilation and heating of the mirrors.

To send the image with the top of the mirrors on the bottom panoramic mirror visible to a driver, in the absence of special holes in the roof possible use is to have sunroof or transparent roof or transparent part of the roof (quite narrow transparent strip in the roof). In this case, the upper part of the mirror system is located above the front part of the roof.

Additional mirrors may be located below, above or to the side of the top of the mirrors.

One option is the location of the additional mirrors in the same block as the top mirror. The close location of the top and additional mirrors will reduce the size of the mirrors, will improve image quality, will facilitate the adjustment of the mirrors, will create a more compact, streamlined case for protection from sun and weather, and to reduce the size of the transparent area in the roof needed to transmit a full picture on the bottom panoramic mirror. In this embodiment, the upper mirror can be positioned vertically or close to this position, which improves visibility of the far spaces.

When the location of the top mirror at an acute angle to a vertical line additional mirrors may be near the bottom panoramic mirrors.

You can locate the additional mirrors for the rear window of the vehicle. In this case, the image is transmitted to the mirror located at the upper edge of the windshield. The upper part of the mirrors in this embodiment is better positioned in the middle or back part of the roof. Additional mirrors for the rear window of the cab it is also desirable for the transparent cover sleek case with heat.

1. The location of the top of the mirrors in the upper part of the cabin over a hole in the ceiling and in the roof.

Figure 1, 2, 3, 4, 5, 6, 7, 8 and 9 shows a schematic of the locations of the upper mirror in the upper part of the Sal is on over the cut out in the roof of the vehicle wide hole 14, the corresponding dimension of the upper mirrors.

Cut in the roof opening 14 from the top tightly closed by a transparent dome 15 with tinted visor 16. Inside the dome provides ventilation and heating. Under the dome above the level of the rest of the roof are the top mirror 6 and 8. The possible combination of top mirrors for anterolateral 6 and posterolateral spaces 8, it is possible to use mirrors only for posterolateral spaces depending on the task.

Mirrors can be flat (figure 2), or spherical, or aspherical (figure 4, 7, 9, 12 and 16), or cone.

Figure 1 presents one of the options combined arrangement of the upper mirrors for anterolateral and posterolateral the surrounding spaces. Both mirrors are installed on the same telescopic or other design rack 18, each mirror has its axis 17 to adjust the angle.

Mirrors for anterior and anterolateral review reflect the image of the surrounding space on the bottom panoramic mirror 7, which is visible by the driver. The upper 6 and lower mirrors 7 are almost parallel to each other, so the driver sees a direct mirror image.

Mirrors to browse back and posterolateral spaces 8 in this embodiment is located at an acute angle in the vertical line. The image of the surrounding space may reflect the lower mirror located at an acute angle to the upper mirror, but in this case, the driver will see an inverted image. Need additional mirror or lens to get the driver direct mirror image.

Better bottom mirror 9 is positioned almost parallel to the upper mirror 8. In this case (figure 1), we obtain a direct mirror image, but directed away from the driver. Angle of this mirror is located panoramic mirror 10 in a position accessible to the gaze of the driver. Intermediate the lower mirror may be called additional mirror 9. Each of these mirrors 9 and 10 have the axis 17 to adjust the angle.

Bottom panoramic mirrors can be installed, for example, on the dashboard, on the side of the driver, in a convenient place.

Figure 2 presents an option shown in figure 1. View from the top. Used flat mirrors. The top and bottom of the mirror system is composed of at least three mirrors to reflect the front or rear of the space, as well as to reflect the left and right side spaces. Each part is reflected by the upper mirror space is projected onto the corresponding part of the additional and bottom mirrors. So the rays from the mirror 6A into the mirror 7a, the rays from the mirror 6b fall on C is rculo 7b, with the 6V mirror - mirror 7b. In the case of posterolateral panorama rays with mirrors 8A enter additional mirror 9a, then the mirror 10A visible to a driver, etc. In each case, the driver sees a continuous panorama of the posterolateral or anterolateral spaces.

System flat mirrors more complex than spherical or aspherical mirrors, but it gives a more correct picture of the visible objects and distances honey them.

Figure 3 presents also the option of a combined arrangement of the upper mirrors for anterolateral and posterolateral the surrounding spaces. However, in this embodiment, an additional mirror 9 is located under the dome 15 behind and slightly below the top of the mirror 8. In this case, the upper mirror 8 is positioned vertically or almost vertically. This provision mirrors improve visibility posterior and posterolateral areas. The image is reflected on a panoramic mirror 10 around which there are no additional mirrors.

4 shows a top view of this option. The use of spherical, aspherical or conical mirrors. This simplifies the entire structure. Additional mirror 9 is located behind the mirror 8, reflecting all the posterolateral space.

Figure 5 also presents the option of a combined arrangement of the top see the feces for anterolateral and posterolateral the surrounding spaces. In this embodiment, an additional mirror 9 is located in the same block as the top mirror 8. In this case, the upper mirror 8 is positioned vertically or almost vertically.

All presented variants possible height adjustment of the location of the mirrors and the angle of inclination.

Figure 6 shows a variant of the location of the top of the mirrors under the dome 15 only for review, posterior and posterolateral spaces 8. Reflected from the upper mirror 8 rays through additional mirror 9 are on the panoramic mirror 10, which is visible by the driver. In this embodiment, the adjustment of the upper mirror 8 and an additional mirror 9 special arms 19 are available to the driver. Maybe this option will be the most popular.

Figure 7 presents a top view of this option. Panoramic mirror 10 is located on the instrument panel to the right of the driver.

On Fig presents the easiest option: at sufficiently close to the location of the top mirrors for posterolateral panorama to the front edge of the roof they can be accessed direct the gaze of the driver.

Figure 9 presents a top view specified on Fig option.

In these embodiments, the top mirror is actually located inside the cabin, with all the attendant advantages.

2. The location of the top mirror above the windshield.

Figure 10 presents the scheme is but one of the options for the location of the upper mirror the anterolateral 6 and posterolateral panoramas 8 above the windshield 1. Mount mirrors possible to the front posts or to the roof of the vehicle. The height of the top of the mirrors can be adjusted remotely by the driver. Also provides a mechanism for changing the angle of inclination of the mirrors. It is better to put all the top mirror in a transparent case 15, preferably with heating.

System top mirrors, as in the previous embodiments, may consist of individual flat mirrors or spherical, aspherical or conical mirrors.

The location of the bottom panoramic mirrors that are visible to a driver, similar to the scheme shown in figure 1. It is possible to use the diagram shown in figure 5, where additional mirror 9 for posterolateral panorama is located in the same block as the upper mirrors 8.

The only difference is that reflected from the upper mirror or additional mirrors rays pass through the windshield.

This option can be used separately as a mirror anterolateral panoramas and mirrors posterolateral panorama.

Figure 11 presents a very simple layout mirrors for posterolateral panorama over the windshield, available to the gaze of the driver.

Top view of this variant is shown in Fig.

3. The location of the top mirror above the roof of the vehicle.

The following options relate to the location C is theme of mirrors for posterolateral panorama over the roof of the vehicle.

On Fig presents layout top mirrors for rear and posterolateral review at the end of the open top of the hatch 12. Additional mirrors 9, casting the image of the back and side areas of the upper mirror 8 on the panoramic mirror 10, are located behind and below the top of the mirrors in the thickness of the roof 2 or more protruding beyond. Possible location of additional mirrors 9 in one unit with the upper mirror 8. The disadvantage of this option is the need to constantly keep the sunroof open.

On Fig presents a variant of the location of the upper mirror 8 for an overview of posterolateral spaces on the roof ahead of the transparent part of the roof 13. Additional mirror 9 may be located posterior to and below the upper mirror on the roof, in the roof or under the transparent part of the roof with the possibility of transferring the image from the top of the mirror through the transparent area of the roof 13 on the lower panoramic mirror 10. Possible location of additional mirrors 9 in one unit with the upper mirror 8 like the version shown in figure 5. Over the top and additional mirrors is transparent case 15.

On Fig presents an option of placing additional mirrors 9 behind the rear window 3 of the vehicle. In this embodiment, the upper mirror 8 can R spoliate average, and in the posterior part of the roof. Depends on the volume image side space. Panoramic image of the rear and side spaces is reflected through additional mirror 9 on the standard interior rear view mirror 11. The upper mirror 8 and an additional mirror 9, it is desirable to close from the weather transparent case 15.

Top view of this variant is shown in Fig.

The proposed location of the mirrors create the conditions for a complete panorama of the surrounding vehicles without "dead" zones, thus increasing road safety. There is no need for side mirrors, increasing the dimensions of the machine, eliminating the need for permanent transfers of sight from one side mirrors the other in which I only see one side of the surrounding space.

Mirrors located above the roof, are eligible for a full overview of the surrounding spaces and less prone to contamination.

Considering all the advantages of the high location of the mirrors, in the future, in roof construction vehicles may have a special streamlined transparent ledge for placement of the upper part of the mirror for a good overview of the surrounding spaces with additional mirrors, providing a reflection of all visible panorama on the lower p is normee mirror. In this case, highly placed mirrors will have all the advantages of interior mirrors.

The invention relates to lighting, in particular mirrors for vehicles, and for the device rear view (review), mainly cars

FIELD: mirror systems of observation.

SUBSTANCE: coordinates of point of driver's eye and reference point at object to be observed in the driver mirror are measured by rule as well as reference point at mirror of transportation vehicle. Angles of inclination of mirror to coordinate planes are found from relations mentioned in formula of invention. Inclination of driving mirror to coordinate planes is determined. Random point at object of observation is preset and its coordinates are measured by means of measuring tape. Coordinates of point in mirror are calculated where the light beam reflects from the mirror and enters driver's eye. Procedure repeats many times for many random points at object of observation and coordinates of corresponding points of reflection at plane of mirror are found. Shape and sizes of mirror are determined by end points of reflection.

EFFECT: simplified determining of shape and sizes of mirror; improved precision of orientation.

SUBSTANCE: in the first version, the method includes determination of presence of a vehicle moving ahead along adjacent lane in concurrent direction using video camera, measurement of distance to the vehicle with calculation of its side mirrors "blind area" position and rear vehicle position relative to "blind area", as well as determination of its type and dimensions, warning about hazardous proximity using indicators located in instrument cluster, assistance in the process of vehicle driving through vehicle deceleration in case when driver of vehicle moving ahead along adjacent lane begins to execute unsafe manoeuvre. In the second version, monitoring system switches on video camera, ultrasonic sensors and microcontroller. The ultrasonic sensors located on vehicle front bumper determine position of moving ahead vehicle side mirrors "blind area". Microcontroller produces warning signals for driver about vehicle entry into "blind area" of going ahead vehicle.

EFFECT: higher traffic safety due to automatic monitoring of moving ahead vehicle blind area condition.

SUBSTANCE: invention relates to vehicle construction. A multi-purpose mirror has a body with fastening and position orientation elements, a straight reflecting mirror surface, a curved part which supplants the straight part on area, a mirror-forming flat glass, active and passive light emission elements. The reflecting straight part of the mirror is formed by adjoining to the transparent adjacent glass a mirror cushion which is a hollow ellipsoid pumped by a gas - air or nitrogen. The ellipsoid is selected on shape and dimensions, is made of elastic film material and its adjacent wall is coated with a mirror reflecting layer. The reflecting curved peripheral part of the mirror is formed by adjoining the mirror cushion to the transparent adjacent glass. The curved part of the mirror is formed by not adjoining the mirror cushion to the transparent adjacent glass through a protrusion situated on the side of the mirror cushion and obtained through a cut in the transparent adjacent glass. The ratio of the straight and curved reflecting parts of the mirror, as well as the curvature of the curved reflecting parts are controlled through simultaneous or separate control of the pressure of the gas - air or nitrogen - in the mirror cushion and a pressing cushion. Pipes for pumping both cushions come out through a channel to the corresponding means of controlling pumping or pressing the back wall of the mirror cushion with a pressing plate.

EFFECT: high quality of the reflecting surface.
