The invention relates to an optical observation device of vehicles, in particular mirrors front view, and can be applied for the perception of visual information by the driver about the status of areas not visible from the driver's seat of the car.

You know the device is forward looking car in patent GB No. 2210835, IPC 60R 1/10, 1/00 from 21.06.1989, containing a mirror attached to the windshield using the tool with the hole entrance and exit to reflect light from the first mirror reflecting the way to the second, which should be visible to the driver of the vehicle. This overview of the field of view should be effective. Mirrors can be arranged vertically relative to each other, defining an easier entry and exit for the incoming and reflected light.

The disadvantage of this device is that the location of the mirrors at a distance from each other does not provide full information display with oncoming traffic lane from the first mirror in the second. The location of the mirrors may be, for example, outside the service area of the windshield wipers of the vehicle. This reduces visibility and obtain full information from the oncoming lane.

The closest to the technical essence and the achieved effect to the proposed device is a mirror per the last review of the car in the patent GB No. 2088799 from 16.06.1982, IPC 60R 1/10, 1/00. This device is to provide the driver of a vehicle highway with an expanded and improved front field of view in front of the driver includes a set of mirrors located within the housing, for projecting an image of the front view of the path of the view of the road about the changing position of the vehicle. The first mirror located on the opposite side from the driver, is located at an angle to the longitudinal axis of the vehicle to transfer the image to the second mirror, which falls into the field of view of the driver. The second mirror is smaller than the first mirror mounted in the casing with the possibility of adjustment. The installation of mirrors in the casing provides for continuous adjustment in horizontal and vertical directions. Mirrors can be installed either horizontally relative to each other and vertically with the possibility of permutations for vehicles with left-hand steering wheel. Mirrors are set so that the transfer of the image from the first mirror to the second occurs at a sharp angle, and the projection view of the road, which falls within the field of view of the driver will be achieved by the intersection of the horizontal transverse axis of the vehicle at an angle within the range from 25 to 45 (degrees).

The disadvantage of this invention is one which by then, that is a large degree of freedom of arrangement of the mirrors relative to each other and different sizes of the first and second mirrors can make a small error in the image front view of the road, creating a fuzzy image. All of this will disorient the driver of the vehicle when driving. This indicates a lack of information reliability of the device. Obtaining a clear and complete image involves the selection of the optimum sizes of both the mirrors and the distance between them and the distance from the second mirror to the driver.

The purpose of the proposed device is to improve the image quality and reliability in use due to improve visibility when driving the right of the road with oncoming traffic.

This task is solved by means of two mirrors mounted inside the vehicle on a rigid frame at an angle to each other with the possibility of a periscope effect and reflection of the front part of the road, while mirrors are arranged vertically relative to each other and placed at the left edge of the windshield with adjustable. The same size mirrors on the size and distance between them and the distance to the driver have the following relationship: B1:In2=(L1+L2):L2where B1In2- ignominiously reflecting surfaces of the first and second mirrors, respectively;

L1, L2- distance from the first mirror to the second and from the second mirror to the driver, respectively.

The bottom mirror, falling within the field of view of the driver mounted on the same horizontal with an outside rearview mirror.

The vertical arrangement of mirrors on a rigid frame and close their location gives the minimum distortion during signal transmission, creating a compact design, and allows you to transfer the entire image from the first mirror reflecting the front part of the road, on the second falling within the field of view of the driver, because the second smaller than the first size. The use of flat mirrors allows you to use the equality of the ratio between the magnitudes of the surface of the mirrors and the distance between them and the driver. Adopted by the vertical arrangement of mirrors eliminates the appearance of obtuse angles between the direct and reflected by the information-rays, eliminating any interference with the driver in the form of glare from the first mirror and the second mirror turned to the driver completely, and the information beam at an acute angle falling within its field of view, creating a clear and complete image of the anterior part of the road.

The compact arrangement of mirrors in the left part of the windshield around its edge enters the service area of the wiper, so the review is always there with two mirrors on the front of the door the guy, and the driver. Mirrors can be mounted on a rigid frame that eliminates vibration and contributes to the quality of the image.

The location of a system of two mirrors next to the external rear view mirror increases the convenience of obtaining timely information about the situation on the road with rear view and front view looking into the left corner of the windshield. The operation of this device is illustrated in the drawings.

1 schematically depicts a rear view (from the car), which shows the vertical position of the two mirrors and the presence of sharp corners at the image acquisition driver.

Figure 2 shows the side view of the surface of the windshield.

Figure 3 shows the wrong lane, which shows two options, increasing the overview of the oncoming lane of the road at the location of the mirror at the left edge of the windshield for vehicles with the right position of the steering wheel, and option B - in the absence of mirrors.

The device comprises a mirror 1 and 2, mounted on a rigid frame 3, which are mounted with the possibility of regulation and adjustment of the mirrors relative to each other (figure 1).

While the same dimensions of the mirrors 1 and 2 in size, and the distance between them and between the second mirror 2 and the driver are the following dependencies: B1:In2=(L1+L2):L2where B1B - same dimensions of the reflecting surfaces of the first and second mirrors, respectively; L1, L2- distance from the first mirror to the second and from the second mirror to the driver, respectively.

The system mirrors front view is as follows.

The first mirror 1 regulate the installation so that it represents the section of road in front in the travel direction of the vehicle, and the image was found on the second mirror 2, which turn so as to reflect the full picture, finally perceived by the driver. Adjustment of both mirrors is inside the cabin and in the future may only need to provide facilities for drivers of different heights or to avoid blinding the driver's headlights in the dark.

Mirror 1, which is opposite from the driver side of the vehicle forms the image of the section of road is closed from the driver, for example, being overtaken by a car. Mirror 2 reads the image and presents it to the driver in his active field of view (figure 2).

The accepted ratio of mirrors and distances of their installation provides complete information perception by the driver. When this equality in the relationship is because you are using flat mirrors.

Both mirrors are in the cabin, not exposed to harmful external impact is, so have a great life and create a clearer image, allowing the driver with greater reliability to assess the traffic situation and contribute ultimately to improve maneuverability at movement. When using this construction, the two mirrors mounted on a rigid frame, allows to increase the angle oncoming lane (figure 3). Adopted by the vertical location of the flat mirrors and their location at an angle to each other allows you to have complete reflection of the oncoming lane from a mirror, reflecting the front part of the road in the mirror, facing the eyes of the driver.

While the accepted arrangement of mirrors eliminates the appearance of obtuse angles between the direct and reflected by the information-rays, increases due to this, the efficiency of reflection, providing high-quality transfer images to the driver, and eliminates any interference in the form of reflections of the first mirror. The location of the bottom mirror in a system of two mirrors reflecting the oncoming lane, on the same level with the external rear view mirror also allows you to get information rear view, which improves the convenience in use.
