The invention discloses an electronic braking system of an FSAC formula racing car. The electronic braking system comprises a VCU, an IPC, an ECU, an MCU, an EBS board, an electromagnetic valve and two sets of sensor assemblies. Each sensor assembly comprises an accelerator pedal sensor, an air pressure sensor and a hydraulic sensor. The VCU sends a dog feeding signal to a watchdog signal on the EBS board so as to ensure that the state of the VCU is normal; the VCU, the IPC and the MCU can mutually receive CAN signals of each other; the two groups of sensor assemblies are respectively distributed on the two CAN buses; the VCU collects sensor data of a part of sensor assemblies, and the MCU collects sensor data of a part of sensor assemblies; and when the sensor data on one CAN bus is abnormal, the sensor data on the other CAN bus is transmitted back to the VCU for updating the state equation of the vehicle. According to the system, dual redundancy protection of a hardware layer and a software layer can be realized, all units can be interwoven for mutual monitoring and protection, and the safety of vehicle driving is ensured.

    本发明公开一种FSAC无人方程式赛车的电子制动系统,包括VCU、IPC、ECU、MCU、EBS板、电磁阀以及两组传感器组件;每组所述传感器组件包括一个油门踏板传感器、一个气压传感器以及一个液压传感器;所述VCU给所述EBS板上的看门狗信号发送喂狗信号以保证VCU的状态正常;所述VCU、IPC以及MCU会相互接收彼此的CAN信号;两组传感器组件分别分布于两条CAN总线上;所述VCU采集一部分传感器组件的传感器数据,所述MCU采集一部分传感器组件的传感器数据;当其中一条CAN总线上的传感器数据出现异常时,另一条CAN总线上的传感器数据传回VCU,用于更新车辆的状态方程。该系统可以实现硬件层与软件层的双重冗余保护,可以把所有单元交织起来,相互监测保护,保证车辆行驶的安全性。
