Automobile active anti-collision auxiliary control device and control method thereof

Abstract

The invention discloses an automobile active anti-collision auxiliary control device and a control method thereof. The automobile active anti-collision auxiliary control device comprises a vehicle sensor module, a pre-processing module, an Internet of Vehicles communication module, a vehicle-mounted auxiliary module and a master control module. The pre-processing module performs preliminary analysis and processing according to the road surface lane information, the vehicle motion state information and the nearby obstacle motion state information which are collected by the vehicle sensor module. The master control module receives the data compiled by the pre-processing module and the Internet of Vehicles communication information and calculate and determine whether collision risks exist ornot, and classifies in a collision form and outputs corresponding control commands to the vehicle auxiliary module. The vehicle auxiliary device module is mainly used for real-time display of controlinformation and voice warning, and performs active braking and steering control to compensate for unnecessary injuries caused by the failure to react or beyond reaction or even faulty operation of a driver.

Description

technical field [0001] The invention belongs to the technical field of automobile active safety, and in particular relates to an automobile active anti-collision auxiliary control device and a control method thereof. Background technique [0002] At present, with the development of society and economy, cars have gradually entered the families of ordinary people. The number of motor vehicles in my country has increased year by year, and the traffic accidents have also increased year by year, causing huge economic and property losses to the society. According to the National Road Traffic Accident Information System, in the traffic accidents that take place, 65% of the accidents are caused by automobile rear-end collisions. Most of them are caused by the driver's failure to respond in time and taking action, so it is very important for the car to actively avoid collisions. [0003] Automobile active collision avoidance is to send an alarm to the driver or actively take measure...

AI Technical Summary

Problems solved by technology

However, the existing active collision avoidance system simply collects the speed and distance of the vehicle in front relative to the vehicle based on the sensor to calculate whether there is a possibility of collision. When there is a large angle between the two vectors of relative distance and relative speed, it will cause Inaccurate collision judgment

[0004] At the same time, the existing automotive safety technology is mainly focused on safety early warning, and the application of active safety is less, and it is "one vehicle, one system". Form a scientific and effective safety information network, which limits the role of automobile safety technology to a large extent
