The invention discloses an emergency lane keeping control method and system, electronic equipment and a medium. The method comprises the following steps that S1, the front wheel speed of a vehicle is obtained from a preset vehicle state sensing system; s2, performing vehicle bumping grade division according to the front wheel speed of the vehicle; s3, performing road type division according to the curvature radius of the road; acquiring a steering wheel angle, adjusting an emergency lane keeping function triggering condition when the vehicle jolts according to the vehicle jolting level, the road type and the steering wheel angle, and issuing a reverse torque opposite to the steering wheel angle. According to the vehicle bumping grade, the road type and the steering wheel angle, the emergency lane keeping function triggering condition during vehicle bumping is adjusted, the reverse torque opposite to the steering wheel angle is issued, the vehicle is corrected back to the corresponding torque direction, steering wheel angle deviation is reduced, the emergency lane keeping function triggering is more accurate, false triggering is reduced, and the safety of the vehicle is improved. Therefore, the driving comfort is improved.
本发明公开了一种紧急车道保持控制方法、系统、电子设备及介质,所述方法包括以下步骤:S1:从预设的车辆状态感知系统获取车辆的前轮速;S2:根据车辆的前轮速进行车辆颠簸等级划分;S3,根据道路曲率半径,进行道路类型划分;获取方向盘转角,依据车辆颠簸等级、道路类型、方向盘转角,调整车辆颠簸时紧急车道保持功能触发条件,下发方向盘转角相反的反向力矩。本发明依据车辆颠簸等级、道路类型、方向盘转角,调整车辆颠簸时紧急车道保持功能触发条件,下发方向盘转角相反的反向力矩,将车辆向对应的力矩方向纠回,减小方向盘转角偏移,使得紧急车道保持功能触发更加精确,减少误触发,以提高驾驶舒适性。
