Speed limiting type reversing control system

Abstract

The invention discloses a speed limiting type reversing control system. The speed limiting type reversing control system mainly comprises a reversing control unit, a gear position sensor, an accelerator pedal position sensor, a speed sensor, an ultrasonic ranging device, a throttle valve device and a speech prompt device. The reversing control unit compares the actual distance, detected by the ultrasonic ranging device, from a barrier behind a vehicle and the vehicle traveling speed detected by the speed sensor with the safety distance and the highest safety speed stored in the reversing control unit correspondingly, then controls the throttle valve device at the output end to conduct active speed limiting on the vehicle and controls the voice prompt device mounted on a center console to give a voice prompt to a driver. Through the speed limiting type reversing control system, collision and scratch accidents caused by the problems such as too high reversing speed and accelerator pedalmisapplication of the vehicle can be prevented, and the reversing safety is improved. Meanwhile, the speed limiting type reversing control system is low in cost, simple in structure, convenient to useand practical.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a speed-limiting reversing control system. Background technique [0002] With the rapid development of science and technology and the continuous improvement of living standards, cars have become a must-have for ordinary families, bringing a lot of convenience to people's life and work, but they have also caused many traffic accidents during people's use. Among them, collisions and scratching accidents with rear obstacles (pedestrians, vehicles, walls, etc. that hinder reversing) are more common when reversing. This is due to the limited vision of the driver when reversing, the large blind spot for reversing, and easy misuse. The reason is that the existing reversing radar and reversing image technology can only prompt the driver through voice and video, but cannot realize active speed limit, so as to prevent problems such as excessive driving speed and accidental stepping on the accele...
