The invention discloses an intelligent lane keeping system based on extension logic and a control method. The system comprises a camera, a road adhesion coefficient observer, a steering wheel angle sensor, a signal processing module, an extension module, an ECU, a steering module and a differential brake module. When the vehicle runs, the signal processing module calculates the transverse lane offset of the vehicle according to information collected by the camera, and when the offset is larger than a threshold value, the lane keeping system based on the extension logic is started; the ECU coordinates and controls the steering module and the braking module to work according to domain signals, transmitted by the extension module, of the vehicle, and therefore the lane keeping performance ofthe vehicle is improved.
本发明公开了一种基于可拓逻辑的智能车道保持系统及控制方法,该系统包括摄像头、路面附着系数观测器、转向盘转角传感器、信号处理模块、可拓模块、ECU、转向模块、差动制动模块;车辆行驶时信号处理模块根据摄像头采集到的信息计算车辆的横向车道偏移量,当偏移量大于阈值时,基于可拓逻辑的车道保持系统启动;ECU根据可拓模块传来的车辆所处的域信号,协调控制转向模块、制动模块工作,从而提高车辆的车道保持性能。
