Embodiment Construction
[0011] Below in conjunction with accompanying drawing, patent of the present invention is described further.
[0012] as attached figure 1 As shown, the patent of the present invention is composed of a camera part, a controller LAN bus signal processing part and a reversing signal processing part. When reversing, the environment behind the car forms a reversing video image through the photosensitive chip inside the camera and the internal memory. At the same time, the signal processing part of the controller LAN bus is connected to the car’s on-board diagnostic system interface to obtain the current steering wheel position of the car. Position, superimposed on the output reversing video screen to display the vehicle movement trajectory. The reversing signal processing part detects the distance and orientation information of obstacles through the ultrasonic sensor, and obtains the distance and azimuth of the obstacle behind the vehicle through the reversing radar host. The di...

The invention provides a reversing radar system adopting color character track lines and belongs to the field of vehicle signal devices. The system comprises a camera part, a controller LAN (local area network) bus signal processing part and a reversing signal processing part, wherein the camera part comprises a light-sensitive chip and a memorizer; the controller LAN bus signal processing part comprises a main control chip, an independent controller LAN protocol controller and a controller LAN bus interface; the reversing signal processing part comprises an ultrasonic transducer and a reversing host. Each functional circuit of the system is simple in structure, stable in performance and convenient to mount and observe, the distance and the orientation of an obstacle at the tail part of a vehicle can be displayed on any display screen through videos output by the system, the reversing motion track is displayed according to the current vehicle steering wheel position and the vehicle motion trend, meanwhile, the distance and the orientation of the obstacle are read with languages, the safety of the vehicle during reversing is improved, and the system can be widely applied to various vehicles during reversing.
Description
Technical field [0001] The invention of the colorful character rail on the inverse line of the inverse radar system belongs to the field of vehicle signal device, especially involving a vehicle reverse indicator. Background technique [0002] For a long time, bad viewing after the car reversing has always been a major problem for car drivers, especially when the climate environment is harsh and the parking position is small, it is easy to collide.The principle of detection, when the car is reversed, a bee tweee prompts the sound, the digital tube shows the distance of the obstacle, but it cannot be detailed in detail.The drive device of the camera can understand the rear of the car, but cannot accurately know the distance of the obstacles, and the camera has a dead end.The above reversing devices are only unilaterally auxiliary drivers reversing.When reversing, the driver must visually determine the distance between the tail and obstacles of the car and the obstacles for a moment...
