The invention discloses an automobile electronic stability control system and a vehicle. According to the system, by arranging a hardware redundancy mode of the first inertial measurement unit chip and the second inertial measurement unit chip, the occurrence of common cause failure is avoided at the same time, so that the occurrence of a fault of the automobile electronic stability control system caused by the abnormality of a single inertial measurement unit chip is avoided, and the safety of a vehicle is improved. When the micro-control unit detects that the first speed information and the second speed information are different, the micro-control unit sends the instruction that the vehicle enters the safe state to the actuator to enable the vehicle to execute the action corresponding to the instruction that the vehicle enters the safe state instead of controlling the vehicle track based on wrong speed information, and the probability that the vehicle is in danger is reduced. Through a hardware redundancy safety mechanism, the diagnosis coverage rate is 99%, so that the single-point fault measurement is improved to be greater than 99%, the standard required by ASIL-D can be realized, and the probability that the vehicle is in danger is further reduced.

    本发明公开一种汽车电子稳定控制系统以及车辆。该系统通过设置第一惯性测量单元芯片和第二惯性测量单元芯片的硬件冗余方式同时避免共因失效的情况的发生,来避免由于单个惯性测量单元芯片异常造成汽车电子稳定控制系统的故障的发生,从而提高了车辆的安全性。通过微控制单元检测第一速度信息与第二速度信息不同时,发送车辆进入安全状态指令至执行器让车辆执行车辆进入安全状态指令对应的动作,而不是基于错误的速度信息对车辆轨迹进行控制,减少车辆发生危险的概率。通过硬件冗余的安全机制使得诊断覆盖率为99%,从而将单点故障度量提高到大于99%,从而可以实现ASIL‑D所要求的标准,进一步减少车辆发生危险的概率。
