A vehicle active collision avoidance method

Abstract

The invention discloses an initiative anti-collision method of a vehicle. The initiative anti-collision method comprises the following steps of firstly judging whether the collision in a driveway can be avoided through automatic braking or not by a system when the driveway which is in risk of collision is monitored by the system; braking in the current driveway if judging that the collision in the current driveway can be avoided through the automatic braking, and sounding a warning; determining a steering angle of a steering wheel when the vehicle is in steering escape if judging that the collision can not be avoided through the automatic braking but can be avoided through the steering escape, and carrying out the steering escape based on the steering angle of the steering wheel; braking in the current driveway if judging that the collision cannot be avoided through the automatic braking and the automatic steering escape, and sounding a warning; and continuously monitoring the surrounding environment of the vehicle if judging that the risk is removed. According to the initiative anti-collision method disclosed by the invention, an automatic steering function is added on the basis of a traditional direct collision system, corresponding judgement is added by an algorithmic logic, and the vehicle collision is prevented from happening to the maximum.

Description

technical field [0001] The invention belongs to the field of automobile safety and relates to vehicle anti-collision technology, in particular to an anti-collision method with steering control function. Background technique [0002] With the continuous popularization of automobiles, the market demand for automobile safety systems is increasing. Since the advent of electronic stability control systems, the development of active safety technology has entered a high-speed era. Lane departure warning system, blind spot detection system, lane keeping system, parking automatic steering system, frontal collision prevention system and other systems are more and more expected by people. [0003] Traditional frontal collision prevention systems, when detecting that a frontal collision is unavoidable, can only reduce the intensity of the collision with the vehicle in front through automatic braking. This can indeed avoid the losses caused by vehicle accidents as much as possible, but ...

[0003] The traditional frontal collision prevention system, when it detects that the front collision is unavoidable, can only reduce the intensity of the collision with the front car through automatic braking

This can indeed avoid the losses caused by vehicle accidents as much as possible, but there are two problems at the same time: 1. If there is a vehicle behind the vehicle, automatic braking is likely to cause a secondary collision between the vehicle behind and the vehicle, resulting in a series of collisions Accidents; 2. Vehicles can only judge the situation in this lane, but often in places with small traffic flow, there are no cars in the side lanes. If automatic steering is used, accidents can be completely avoided.
