A vehicle collision avoidance control method based on driver's collision avoidance behavior

Abstract

The invention discloses a vehicle collision avoidance control method based on a driver collision avoidance behavior. The method includes the steps that firstly, driver lane changing collision avoidance time, the braking acceleration and the time spent by a driver to make a response when an alarm signal is received are acquired through a driving simulation instrument, and related information, required by the vehicle collision avoidance control method, of an own vehicle, a front vehicle and vehicles on adjacent lanes is detected in real time through millimeter wave radar; secondly, a rear-end collision avoidance control strategy based on the driver collision avoidance characteristic is established; then, the own vehicle executes a braking or lane changing collision avoidance control strategy; and finally, the accuracy of the collision avoidance control strategy based on the driver collision avoidance characteristic is verified. By the adoption of the method, the negative effects on a judgment result due to a complex early warning algorithm and too many decision judgment rules are reduced, the accuracy and the reliability of vehicle collision avoidance control decision judgment are improved, and the false alarm rate is reduced.

Description

technical field [0001] The invention belongs to the field of motor vehicle driving safety, in particular to a vehicle collision avoidance control method based on the driver's collision avoidance behavior. Background technique [0002] Vehicle rear-end collision is one of the main forms of vehicle-vehicle collision. Vehicle-to-vehicle collisions can be divided into frontal collisions, lateral impacts, and rear-end collisions. Among them, rear-end collisions accounted for the largest proportion. In 2012, rear-end collisions accounted for 32% of national expressway accidents. Therefore, when there is a risk of rear-end collision, especially when the driver is not aware of it, it is of great significance to give the driver fast and accurate collision avoidance control decisions, which can reduce the occurrence of traffic accidents. In order to reduce the occurrence of rear-end collision accidents and improve road safety The level of traffic safety is of great significance. [...
