The invention relates to a vehicle control system and a processor reset protection circuit, and belongs to the technical field of vehicle safety control. A shift register is used for storing a vehicle state signal and a control signal, and before resetting, a processor writes the state signal and the control signal into the shift register and transfers the control signal to a storage register; during resetting, the shift register latches a signal stored at the previous moment; and after resetting, the processor reads the signal in the shift register, and vehicle state recovery is carried out according to the signal in the shift register. In this way, the original state can be quickly read and recovered after resetting, the safety of the vehicle is ensured, and when the processor is reset, the output state is not changed, and external equipment does not act abnormally. In addition, storage of the state data through the shift register is not limited by processor resources.
本发明涉及一种车辆控制系统及处理器复位保护电路,属于车辆安全控制技术领域。本发明利用移位寄存器来存储车辆状态信号和控制信号,复位前,处理器将状态信号和控制信号写入移位寄存器中,并将控制信号转存给存储寄存器;复位时,移位寄存器对前一刻的存储的信号进行锁存;复位后,处理器读取移位寄存器中的信号,根据移位寄存器中的信号进行车辆状态恢复。这样复位后能够快速读取并恢复至原来的状态,确保了车辆的安全性,并且在处理器复位时,输出状态不变,外部设备不会异常动作。此外,通过移位寄存器保存状态数据也不会受到处理器资源的限制。
