Abstract

The invention discloses a front collision avoiding system based on driving behavior of a front vehicle driver and a vehicle collision avoiding algorithm. The front collision avoiding system consists of laser radar, a front vehicle driving information acquisition camera and a video processor hardware platform, wherein the laser radar is used for acquiring the distance between a vehicle self and a front vehicle, the speed of the front vehicle and the acceleration of the front vehicle; the front vehicle driving information acquisition camera is used for acquiring a front vehicle left turn light, a front vehicle right turn light, front vehicle brake lights and vehicles in adjacent lanes of the front vehicle. By analyzing driving parameters of the front vehicle and information of vehicles in adjacent lanes of the front vehicles, a prediction model of driving behavior of the front vehicle driver can be established, and a collision avoiding scheme set can be designed. Two evaluation indexes of security and stability can be established. A collision avoiding optimization function based on two-dimensional weight can be established, particle swarm optimization is adopted to optimize collision avoiding schemes, and thus optimal collision avoiding schemes can be obtained.

Description

technical field [0001] The invention relates to the field of smart cars, in particular to a forward collision avoidance system based on the driving behavior of a forward vehicle driver. Background technique [0002] With the rapid growth of my country's car ownership, the number of non-professional drivers is gradually increasing, which indirectly leads to the frequent occurrence of traffic accidents. Aiming at the causes of accidents, researchers have been working on how to reduce the occurrence of accidents through effective measures, among which systems such as vehicle-road coordination and driving safety assistance are an effective way to improve vehicle operation safety. Among them, the vehicle forward collision avoidance system, as an advanced vehicle safety driving assistance technology, has been concerned by scholars at home and abroad. However, at present, the forward collision avoidance system of automobiles is mainly based on the speed, acceleration and parameter...
