The group of inventions relates to the field of traffic safety of vehicles (TC) and the technical solutions for detection of a moving object (vehicle or pedestrian)crossing the trajectory of the vehicle or coming to it for the purpose of crossing.

For vehicles characterized by two types of movement in the direction of travel and reverse.

Typically, the security of the vehicle is provided visually by the driver on the basis that the driver is obliged to assess the situation in front of the car or behind it and to ensure that this choice of motion parameters (speed, lane, and so on), which excludes the impact with another vehicle or an obstacle or a pedestrian.

The cabin dimensions of the vehicle is located at a sufficient height from the road surface, making it difficult for the driver review under the front wheels because the front of the cabin for the driver dead zone of visibility. When turning this overall vehicle driver does not control the anterolateral area - he does not see.

The same applies to almost all vehicle vehicle type buses, goods vehicles and passenger vehicles with elongated anterior part of the body (the engine). If the driver takoh the car starts to turn, and at the turn of another parked car, the traffic situation, the driver can be assessed only after the front part of his car is almost completely will leave for the rotation.

Parking reversing (reversing) is one of the most difficult elements of driving. Reversing't keep from annoying incidents and collisions with various obstacles - fence, curb, a car or a pedestrian.

In conditions where visual driver can not assess the traffic situation due to obstacles, spread technical solutions to ensure visibility using installed on the vehicle video cameras and monitors. This camera come with the possibility of review and shooting of the frontal zone (JP 2010002275 A, B60R 1/00, 07.01.2010; JP 2008114672 A, 22.05.2008; US 2009243880 A1, B60Q 1/00, 01.10.2009), rear area (GB 2463544 A, B60W 30/18, 24.03.2010; GB 2357743 A, B60Q 1/48, 04.07.2001), lateral zones (JP 2009017572 A, B60R 1/00, 22.01.2009), and at the same time all zones (DE 19937489 A1, B60Q 1/52, 08.02.2001; EN 2007123679 A, B60R 21/00, 27.12.2008 - prototype). Received camera image traffic is reproduced on the monitor for the driver.

Separate systems with video cameras and monitors only warns the driver about dangerous approach an obstacle and may not prevent the crash. Other system controls only the area in front of the forward or adnim bumpers and not give signal, if an obstacle such as a pedestrian, is located a little to the left or to the right of the vehicle, i.e. on the side of it. Quite possible the situation in which a pedestrian takes a step off the pavement and into the zone, such as the rear bumper. In this case, the signal from the sensors is transferred to the information Board monitor or includes a sound system, but does not prevent hitting, as this information category, a warning is automatically put in the statement.

However, a number of technical solutions using video cameras and monitors to ensure the formation of the control or of the information signal, is sufficient to correct the vehicle is in motion (e.g., in the direction of reducing speed or stopping) or for the organization of visual and audio signals to the driver about the upcoming event.

We emphasize that are potentially dangerous frontal obstacles that arise on the side of the car. This applies to moving objects (vehicle or pedestrian)that intersect (coming with the purpose of crossing to the trajectory of the vehicle movement. The need for control over such sites are the most relevant in conditions of poor lighting of roads, or no lighting at all. In the dark illumination of the road is provided only by the headlights of the car and so is the lack of road lighting lantern poles, the driver is unable to see the approaching to the road or walking along the roadside pedestrian.

However, the known systems do not provide quality control of the traffic situation and not allow maneuvering vehicle with a high level of security in case of lateral obstacles.

The present group of inventions aimed at solving technical problems on improvement of visual control in the anterolateral area or in the posterolateral area in the direction of travel of the vehicle. Achievable technical result is to increase traffic safety by providing visibility areas are not visually perceived by the driver while moving or when reversing, and identify the driver of the distance towards the object, preventing the maneuvering of the vehicle.

This technical result for the first variant (the movement of the vehicle ahead) is achieved by the claimed method of monitoring the traffic situation with a moving vehicle, according to which by means of at least one video camera mounted on the vehicle (vehicle), delivering images of frontal zones in the direction of travel in front of the vehicle and display the image of the traffic situation in this area on the monitor screen for the driver, when you turn on the light turn signal or when steering a vehicle, a voice command, or by activating the advanced button through, kr is ina least one additional camera, mounted in the zone of the front bumper TC, delivering images of anterolateral area while moving in an extra window of the display screen or on top of the image of the traffic situation in the frontal area cause overall of the label describing the boundaries of the provisions of the vehicle when it is going on the road or after the Commission of possible maneuver and display marked on the label area of the display screen image of the traffic situation in the anterolateral area with capability to visually determine the driver of the distance/between the object(s)that prevent (them) to the Commission of possible maneuver.

This technical result for the second option (the movement of the vehicle is in reverse) achieved the declared method of monitoring the traffic situation with a moving vehicle, according to which by means of at least one video camera mounted on the vehicle (vehicle), delivering images of frontal zones in the direction of travel in front of the vehicle and display the image of the traffic situation in this area on the monitor screen for the driver, when you turn on the light turn signal or when steering a vehicle, a voice command, or by activating a button advanced through at least one additional camera, mounted in the ass zone is it bumper TC delivering images posterolateral area while moving in an extra window of the display screen or on top of the image of the traffic situation in the frontal area cause overall of the label describing the boundaries of the provisions of the vehicle when it is going on the road or after the Commission of possible maneuver and display marked on the label area of the display screen image of the traffic situation in the posterolateral area with capability to visually determine the driver of the distance/between the object(s)that prevent (them) to the Commission of possible maneuver.

These characteristics are essential and interrelated with the formation of a stable set of essential features, sufficient to obtain the technical result

The present invention is illustrated by a specific example, which, however, is not only possible, but clearly demonstrates the possibility of achieving a given set of features required technical result.

Figure 1 shows the placement of cameras on the car for visibility when driving in forward motion; Fig.(photo) 2 - front view which the driver sees through the windshield of Fig.(photo) 3 - same as in figure 2, the image obtained from the front of the working camera, and Fig.(photo) 4 - look with the eyes of the manufacturer at the check-out at the T-junction; in Fig.(photo) 5 - same as figure 4, the image obtained with additional video cameras, placed in the zone of the front bumper; Fig.(photo) 6 - view from the rear camera front view (above the license plate) at check-in TC in the arch of the back; Fig.(photo) 7 is the same as in Fig.(photo) 6, the image obtained with additional camera review posterolateral area of the vehicle, mounted in the rear bumper.

According to the present group of inventions presents variants of the method of monitoring the traffic situation from a moving vehicle providing additional review areas, visually inaccessible to the driver while driving forward or reverse.

Method of monitoring the traffic situation from a moving vehicle while moving forward is that by means of at least one video camera mounted on the vehicle, delivering images of frontal zones in the direction of travel in front of the vehicle and display the image of the traffic situation in this area to monitor for the driver. However, before or during the Commission of the maneuver, for example when rebuilding or turn, optionally through at least one additional camera, mounted in the zone of the front bumper TC, delivering images of anterolateral zone in the direction of travel and display the image of the traffic situation in this area to monitor DL the driver in the form of an additional window or on top of the image of the traffic situation in the frontal area.

This includes additional video camera, i.e. start videotaping, when you turn on the light turn signal or when steering a vehicle, a voice command, or by activating a button.

When reversing, through at least one video camera mounted on the vehicle, perform the capture zone for the vehicle and take a picture of traffic situation in this area to monitor for the driver. But when reversing when turning the steering wheel or by voice command, or by activating a button through at least one additional camera, mounted in the rear bumper TC, delivering images of posterolateral zone in the direction of travel and display the image of the traffic situation in this area to monitor for the driver in the form of an additional window or on top of the image of the traffic situation in the rear area.

System better overview for implementing the inventive methods is mounted on the vehicle and can be arranged as follows.

The car has a built-in computer or processing unit with a monitor mounted with regard to the disclosure of the airbag in the center front of the salon in the field of vision of the driver, there are several video cameras.

The video camera 1, reflecting the situation in front of the vehicle, mounted on a remote stand is in the rear fenders of the vehicle.

Video camera 2, reflecting the situation in the anterolateral area of the vehicle, are mounted on the front bumper in the corners (in the zone of the front bumper).

Camcorder, reflecting the situation behind the vehicle and in the posterolateral area, mounted in the area of the license plate on the rear bumper (rear bumper).

On the monitor when the camera 1 can simultaneously display images from these cameras: front area in front of the car. Thus, the driver always sees what is happening in front of vehicle, including in the lateral frontal zones.

Figure 2 presents a front view of the eyes of the driver, and figure 3 presents a picture of the same road conditions with camera overview front.

Figure 6 shows the image from the rear of the front camera on the arrival at the arch, and figure 7 - image of the same road conditions with camcorder review posterolateral zone.

In the closest analogue (EN 2007123679 A) overall marks are applied on the images received and displayed by the monitor cameras overview of the frontal zone (figure 3 and 7). These labels represent the boundary position of the TC, if it came to a road. Due to the marked overall labels the driver knows in advance about the potential possibility or impossibility of the passage width in their own and neighboring bands.

When turning on the light UCU is the motor turning in addition, the monitor displays images from additional cameras. Actual it is at the exit of the arches, the passage of the T-shaped intersections. These advantages are clearly visible in figure 4 and 5. So figure 4 shows the appearance of the eyes of the driver to leave the car at the T-junction, and figure 5 is an image with the camera at the same position of the vehicle, as in figure 4.

In the claimed methods, unlike the prototype, the dimensions of the labels are applied on the images received from cameras review of lateral zones and displayed in an additional window of the display screen or on top of the image of the traffic situation in the frontal area. These labels represent the boundaries of the provisions of the vehicle when it is going on the road or after the Commission of possible maneuver. Due to the marked overall marks (7) the driver can visually determine the distance/between the object(s)that prevent (them) to the Commission of possible maneuver. This is just enough information to understand the fundamental capabilities of maneuver without interference with other traffic participant.

The computer is configured so that during the movement of the TC display only images with cameras or GPS navigation. The computer continuously records images from all the cameras, turn on light indicator, etc. on the hard drive - HDD and removable media, which is circular for the of n the last 5-10 minutes.

Thus, the claimed group of inventions is provided: increase the driver's visibility, video recording while driving, when the widespread use of turning light indicator a large number of drivers, driving with fewer rebuilds, environmental improvement (decrease of gasoline consumption), less wear of the brake pads.

The group of inventions capable of industrial application, as it can be implemented using known electronic technologies used for electronic control.
