The invention discloses an independent redundant wheel speed processing system. The system comprises four wheel speed sensors arranged on four wheels respectively; the four wheel speed sensors are respectively in communication connection with the MCU through the four wheel speed signal processing units; the four wheel speed signal processing units diagnose driving abnormity and wheel speed signal abnormity of the four wheel speed sensors respectively and send diagnosis results to the MCU. The independent wheel speed signal processing unit is adopted, the function safety requirement and the function redundancy requirement of the braking system are guaranteed, and meanwhile the high cost caused by the fact that a high-integration-level chip is adopted by the braking system to meet the function safety requirement and the function redundancy requirement is reduced.
本发明公开一种独立式冗余轮速处理系统,该系统包括:分别设于四个车轮的四个轮速传感器;四个轮速传感器分别通过四个轮速信号处理单元与MCU通信连接;四个轮速信号处理单元分别对四个轮速传感器的驱动异常及轮速信号异常进行诊断,并将诊断结果发送至MCU。本发明采用独立分立的轮速信号处理单元,保证了制动系统的功能安全需求和功能冗余需求,同时降低了制动系统采用高集成度芯片为了满足功能安全和功能冗余所带来的高成本。
