The invention discloses a high-sensitivity wheel speed sensor system and a control method, and belongs to the technical field of brake control. The high-sensitivity wheel speed sensor system comprises an ESC controller and an EPB controller; the ESC controller comprises an ABS (Anti-lock Brake System) and a yawrate sensor; the ESC controller controls the dynamic stability of the vehicle, and the ABS can prevent wheels from being locked; the yawrate sensor is integrated in the ESC controller, collects the longitudinal acceleration, the transverse acceleration and the yaw velocity of the vehicle, transmits the information to the ESC controller, and assists the ESC controller in judging the state of the vehicle; the EPB controller can be used for parking after the vehicle is stopped; the ESC controller is in signal connection with the EPB controller through a CAN, the ESC controller transmits a wheel speed pulse signal to the EPB controller through the CAN, and the ESC controller collects a yawrate sensor signal in real time through a hard wire; according to the invention, the vehicle speed output by the ESC is processed; and the judgment on the yawrate threshold value is added, so that the passing rate of the production line is improved, and the complaint of the user is avoided.
本发明公开了一种高灵敏度轮速传感器系统及控制方法,属于制动控制技术领域,包括ESC控制器和EPB控制器;ESC控制器包括ABS和yawrate传感器;ESC控制器控制车辆的动态稳定,ABS能够防止车轮抱死;yawrate传感器集成在ESC控制器里,采集车辆的纵向加速度,横向加速度及横摆角速度,并将这些信息传递给ESC控制器,辅助ESC控制器判断车辆状态;EPB控制器能够在车辆停止后驻车;ESC控制器与EPB控制器通过CAN信号连接,ESC控制器将轮速脉冲信号通过CAN传输给EPB控制器,ESC控制器通过硬线实时采集yawrate传感器信号;本发明对ESC输出的车速进行了处理;增加对yawrate阙值的判断,提高了生产线通过率,避免了用户抱怨。
