AI Technical Summary

Problems solved by technology

If the safety distance is too small, rear-end collision accidents are likely to occur, which is not conducive to the safe driving of vehicles; on the contrary, if the distance is too large, the road traffic capacity will be reduced

Abstract

The invention relates to a warning and control device for vehicle safety distance. The warning and control device comprises an information acquisition unit (1), an information processing unit (2) and an information output device (3). The information acquisition unit mainly comprises a millimeter wave radar (4), a vehicle speed sensor (5), a steering angle sensor (6), a brake sensor (7), an accelerator pedal sensor (8), a pavement condition monitor (9) and a driver type selection unit (10); the information processing unit is a central processor (11); the information output device comprises a display screen (12), an alarm buzzer (13) and an alarm indicator lamp (14). The central processor (11) receives signals sent by the millimeter wave radar (4), vehicle speed sensor (5), steering angle sensor (6), brake sensor (7), accelerator pedal sensor (8) and pavement condition monitor (9), and then gives out control strategy based on the vehicle safety distance control model so as to trigger the display screen (12), alarm buzzer (13) and alarm indicator lamp (14) to give out corresponding warning information.

Description

technical field [0001] The invention relates to a vehicle safety distance warning control device. Background technique [0002] At present, the main problem of the early warning control device for vehicle safety distance is the high rate of false alarms, and the second is to rely on the braking system of the vehicle to realize the active braking of the vehicle. The adjustment of the vehicle speed is mainly realized by controlling the opening of the engine throttle and automatically lowering the gear. [0003] With the rapid development of China's economy, cars have become more and more common, followed by frequent traffic accidents. Rear-end collisions on expressways are the main cause of traffic accidents, which not only bring great economic losses to the society, but also seriously endanger people's lives and health. Therefore, research on anti-rear-end collisions is very important. A very important issue in preventing rear-end collisions is the issue of the safety model...
