Problems solved by technology

[0002] Ordinary reversing assistance systems use radar or camera technology to capture information about obstacles, and then feed back signals such as distance and azimuth to the driver after processing. Make corresponding actions (brake or turn the direction) after judgment, there is still the possibility of accidents for novice drivers, and it does not really improve the driving safety of vehicles

Embodiment Construction

[0028] according to figure 1 , The present invention is a fully automatic reversing auxiliary control system, which mainly includes a main control module, an image processing module, an RF receiving module and a CAN transceiver module.

[0029] according to image 3 and 4 , the APAS system is activated and starts to work:

[0030] First, the radar probe starts to work to detect the front, rear, left and right of the car. The main control module judges the obstacles around the vehicle - distance and orientation according to the analog signal generated by the radar probe. Then the camera works to capture the parking line and send the video signal. It is sent to the high-performance image processing module for image recognition processing and analysis of parking spaces, and combined with ultrasonic detection to determine whether there is a suitable parking position;

[0031] Then, the camera shoots the parking line and transmits the video signal to the high-performance image p...

Abstract

The invention relates to a full-automatic vehicle backing minor control method and a full-automatic vehicle backing minor control system. The full-automatic vehicle backing minor control system mainly comprises an image processing module, a radar probe, a CAN transmitting and receiving module and a master control module, wherein the image processing module identifies video signals acquired by a camera and outputs identity signals to the master control module; the radar probe is used for transmitting and receiving ultrasonic waves and outputs ultrasonic wave signals to the master control module; the CAN transmitting and receiving module is used for realizing real-time transmission of information between an engine control unit, a gear box control module, an electronic power-assisted steering unit and an electronic stability control unit; and the master control module is used for processing the signals from the image processing module and the radar probe, responding the signals in the interrupt mode, and maintaining connection with the CAN transmitting and receiving module. The full-automatic vehicle backing minor control method and the full-automatic vehicle backing minor control system solve the problem that a common vehicle backing minor control system can not precisely guide a driver to back a vehicle.

Description

technical field [0001] The invention relates to a fully automatic reversing auxiliary control method and system thereof. Background technique [0002] Ordinary reversing assistance systems use radar or camera technology to capture information about obstacles, and after processing, feedback signals such as distance and orientation to the driver. The actual meaning is only to play an auxiliary role. After judging and taking corresponding actions (braking or steering), there is still the possibility of an accident for novice drivers, and it does not really improve the driving safety of the vehicle. The reversing assistance system developed from the initial voice prompt to ultrasonic radar, and then entered the era of image assistance. These three systems are semi-automatic assistance systems that ultimately rely on the driver to complete the reversing. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a fully automati...
