A vehicle front target recognition system and recognition method

Abstract

The invention relates to a vehicle front target recognition system and a recognition method. The recognition system comprises a system parameter presetting module which presets a yaw speed zero point, a vehicle information and signal acquisition mode, early warning parameters and start-up speed, a yaw speed acquisition module which acquires a vehicle yaw speed signal and calculates a yaw speed value, a vehicle signal acquisition module which acquires a vehicle signal, a configuration information estimation module which is composed of a curvature radius estimation module and a radar information configuration module, a radar which carries out target recognition, a radar signal acquisition module which acquires radar target information in real time, a radar target selection module which is composed of an effective vehicle base updating module and a target selection logic module, an early warning module which respectively compares the vehicle speed with the locked radar target speed and relative speed with distance to produce a collision danger signal, and a man-machine interface module which displays the collision danger signal. The vehicle front target recognition system and the recognition method, which are provided by the invention, can be widely applied to vehicle forward collision early warning.

Description

technical field [0001] The invention relates to a target recognition system and a recognition method, in particular to a vehicle front target recognition system and a recognition method. Background technique [0002] With the continuous increase of car ownership and the expansion of driver groups, road traffic safety has become a serious problem faced by modern society. As one of the important means to reduce traffic accidents, driving safety assistance system has been paid more and more attention. Statistics show that more than 70% of traffic accidents are caused by driver's fault. There are certain fluctuations and limitations in the driver's physiology, psychology, and ability, and it is inevitable that there will be abnormal driving conditions such as fatigue, negligence, and operational errors. Vehicle forward collision warning (Forward Collision Warning, FCW) is an active safety technology for the purpose of assisting drivers to drive safely, and has become one of th...

Problems solved by technology

For example, the automobile anti-collision warning control system or control method in the prior art judges the alarm state and controls the vehicle braking according to the information returned by the radar, and actively decelerates to reduce the collision loss for the inevitable collision, but the prior art There is no solution on how to screen radar targets to ensure the accuracy of system judgment, so it is impossible to screen radar targets accurately and effectively. In this case, misoperation may occur when controlling the vehicle
