The invention discloses a redundancy control method and system for a vehicle electronic stability system and an automobile. The redundancy control method comprises a normal control mode and a redundancy control mode. In the normal control mode, the ESC obtains a vehicle state signal through an inertia sensor and executes an intervention strategy; in the redundancy control mode, the ESC obtains a vehicle state signal and executes an intervention strategy after calculating a signal collected by the vehicle-mounted GPS. The method has the advantages that redundancy control of the electronic stabilization system is provided, and after an inertia sensor of the ESC is damaged or fails, signals needed by ESC work can be obtained through a vehicle-mounted component in a calculation mode, so that redundant reliable operation of the electronic stabilization system is guaranteed, and the reliability of the ESC is improved. Vehicle potential safety hazards caused by the fact that the ESC cannot work after the inertia sensor fails are avoided; the redundancy control scheme is low in newly added hardware cost, mainly software cost, and the control method can be operated by being implanted into the ECU in a program mode.
本发明公开了一种车辆电子稳定系统冗余控制方法及系统、汽车,包括正常控制模式和冗余控制模式;正常控制模式下,ESC通过惯量传感器获取车辆状态信号并执行介入策略;在冗余控制模式下,ESC通过车载GPS采集的信号经计算后得到车辆状态信号并执行介入策略。本发明的优点在于:提供电子稳定系统的冗余控制,在ESC的惯量传感器损坏或失效后,可以通过车载部件通过计算的方式获取ESC工作所需的信号,从而保证了电子稳定系统的冗余可靠运行,避免因为惯量传感器失效后ESC无法工作带来的车辆安全隐患;冗余控制方案新增硬件成本低,主要是软件成本,将控制方法以程序方式植入ECU中即可运行。
