Abstract

The utility model relates to an automobile electronic. To eliminate a blind area of a right rear side during a vehicle-backing and driving out of a garage, the utility model provides a monitoring and early warning system for blind area of a right rear side of vehicles and the system comprises a camera and a display screen. The system is characterized in that the camera (10) is arranged in a right rear side of a vehicle body; a direction of the camera (10) facing is perpendicular to the vehicle body; the display screen is installed in a place where a driver can see and a sight of the driver cannot be blocked; and the camera (10) is connected with the display screen via a video line. The system further comprises a collecting and transmitting device for a steering wheel rotating angles, a tail end camera and a follow-up device of the tail end camera; the two devices are connected in a wire or wireless way; and the follow-up device of the tail end camera rotates via a control to the camera (10) by a servo motor. When the vehicle is backed, the camera rotates with the steering wheel and faces always to the road. Therefore, safety is guaranteed during vehicle-backing.

Description

Automobile right lateral side blind area monitor and early warning system

Technical field

The utility model relates to vehicle electronics.

Background technology

Automobile is played the part of more and more important role in people's routine and life, the motor traffic accidents in recent years of China is very high always then.These a lot of traffic accidents wherein occur in the process of reversing.At reversing, except utilizing vehicle-mounted equipment such as back mirror, general auxiliary solution mainly is methods such as audio communication such as radar/super sonic is reported to the police, reversing video at present.These methods have improved the safety of reversing preferably.

Yet vehicle afterbody right side parallel zone does not cause people's attention, the safety hazard when such blind area may become vehicle backing as yet.As shown in Figure 1, the vehicle 33 of moveing backward and steering position 2 thereof, this vehicle must leave the parking stall in the mode of reversing, and enters in the track 88, and according to the traffic regulation of China's right lateral, this car must be on the right side of road axis 9.In this case, 6 of blind areas are extremely important, because the visual field of chaufeur is blocked by the vehicle 11 on its right side fully, be in particular big-and-middle-sized vehicle, so can't judge the situation on the direction of vehicle afterbody right side almost right angle, if at this moment pedestrian or vehicle process are arranged on this direction, the safety to traffic has increased a lot of hidden danger undoubtedly.No matter be all kinds of big-and-middle-sized vehicles or lilliput car, it is essential that the visual field on this direction all seems.

The utility model content

Blocked the problem in the visual field when pouring out from the parking stall in order to solve automobile by the next door vehicle, the invention provides a kind of automobile right lateral side blind area and detect forewarn system, comprise camera 10 and read-out, it is characterized in that: the right flank at the afterbody of vehicle body is installed a camera, the camera direction is vertical with vehicle body, connects by video line between camera and the read-out.

Automobile tail camera and bearing circle are servo servo-actuated, also be provided with the collection of bearing circle rotational angle and transmitting device and afterbody camera and follow-up mechanism thereof, connect by wired or wireless mode between these two devices, afterbody camera follow-up mechanism rotates by servomotor torque constant control camera 10.

Right lateral side at auto body also is provided with radar early warning system, and the telltale of early warning is arranged on that chaufeur can be seen but the place that do not influence pilot's line of vision.

By device of the present utility model, the blind area of right lateral side when eliminating reversing automobile, the safety when having improved the reversing outbound.

The specific embodiment

Come the utility model is elaborated below in conjunction with accompanying drawing.

Forewarn system is detected in a kind of automobile right lateral side blind area, comprises camera and read-out, it is characterized in that: the right flank at the afterbody of vehicle body is installed a camera 10, and camera 10 directions are vertical with vehicle body, connect by video line between camera and the read-out.

Automobile tail camera and bearing circle are servo servo-actuated, also are provided with the collection of bearing circle rotational angle and transmitting device and afterbody camera and follow-up mechanism thereof, connect by wired or wireless mode between these two devices.

Wherein, wire transmission mode is realized by UART or CAN interface.Wireless transmission method is then finished based on related wireless communication agreement and device, as the transmission over radio based on bluetooth.

As shown in Figure 2, suppose

(1) bearing circle is in normal place, and namely wheel is just beaten, and is parallel with car body.

(2) set up good be connected with transmitting device with afterbody camera and follow-up mechanism thereof to the collection of dish rotational angle, gear is in backing car gear, i.e. the R shelves.

The whole system operation principle is as follows:

In reversing process, chaufeur is cw [1] steering wheel rotation inevitably, and the car body angular separation in the time of this angle and parking is θ, this angle obtains by the rotary angle transmitter that is installed in the bearing circle rotating shaft.Simultaneously, this velocity information is sent out in real time, and is received by afterbody camera follow-up mechanism.The latter drives servomotor torque constant and makes the camera cw turn over equal angular,, namely θ=.

Entering when reversing gear, the servo-electric chance of camera is revised oneself angle automatically according to the respective angles of the bearing circle of receiving, makes the two identical.

When gear left reverse gear (R shelves), camera was not worked, and it can keep leaving the preceding final angle of backward gear (R shelves).

As long as when being in backward gear, the angle of bearing circle and car body and the angle of camera and the tailstock must remain consistent, namely θ=.

But on the road when the right lateral side of reversing vehicle 3 has mobiles 5, because the visual field centerline direction of camera becomes 90 degree with automobile steering, so chaufeur can be seen mobiles 5 by read-out, chaufeur is moved bearing circle, because also rotation thereupon of camera, and the visual field of camera faces toward the centerline direction of road all the time, when rear side has mobiles 5, chaufeur can be known all the time, thus the blind area of the automobile right lateral side of eliminating, and the problem that the visual field is kept off when making reversing is resolved.

Right lateral side at auto body also is provided with radar early warning system, and the telltale of early warning is arranged on that chaufeur can be seen but the place that do not influence pilot's line of vision.Reverse Sensor cooperates camera, has improved the safety of reversing more.
