The invention discloses an intelligent networked passenger car wet and slippery road AEB control system and method. The system comprises a vehicle control unit, and a wheel speed acquisition unit, a motor controller, an image acquisition unit and an AEB system which are respectively connected with the vehicle control unit, the wheel speed acquisition unit is mounted on a hub of a wheel and used for acquiring the wheel speeds of left and right rear wheels of the vehicle; the motor controller is used for outputting motor rotating speed; the image acquisition unit is used for acquiring the distance and the relative speed with a front obstacle; the vehicle control unit receives data acquired by the wheel speed acquisition unit, the motor controller and the image acquisition unit, calculates the current vehicle speed, the vehicle slip rate and the collision time by using the acquired data, and outputs calculation results to the AEB system; and the AEB system determines different deceleration according to the whole current vehicle speed, the whole vehicle slip rate and the collision time. The problem that a current intelligent networked passenger car is prone to drifting when triggered by AEB on a wet and slippery road surface is solved, the drifting risk of the car is reduced, and the safety of the whole car is improved.

    本发明公开了一种智能网联客车湿滑路面AEB控制系统及方法,包括:整车控制器以及分别与整车控制器连接的轮速采集单元、电机控制器、图像采集单元和AEB系统;轮速采集单元安装在车轮的轮毂上,用于采集车辆左右后轮轮速;电机控制器用于输出电机转速;图像采集单元用于获取与前方障碍物的距离和相对速度;整车控制器接收轮速采集单元、电机控制器、图像采集单元获取的数据并利用获取的数据分别计算当前车速、整车滑移率及碰撞时间,将计算结果输出到AEB系统;AEB系统根据整当前车速、整车滑移率与碰撞时间,确定不同的减速度。解决了当前智能网联客车在湿滑路面AEB触发车辆易甩尾的问题,降低车辆发生甩尾的风险,提高整车安全性。
