The invention discloses a wake-up method for a vehicle controller, and the method comprises the steps: carrying out the SPI initialization processing when the controller carries out the power-on processing; when the SPI initialization processing is completed, judging whether the interrupt flag in the interrupt state register is power-on reset; if yes, executing self-checking operation through the read self-checking result data; if not, executing a wake-up source identification process through the data of the input state comparison register; when the self-checking operation or the wake-up source identification process is executed, configuring a switching value acquisition chip; and on the basis of the switching value acquisition chip, switching value monitoring is carried out so as to realize awakening of the vehicle controller. The complexity of the controller of the vehicle in the wake-up process is reduced, and the utilization rate of hardware resources of the controller is increased. The invention further discloses a wake-up device of the vehicle controller, control equipment and a computer readable storage medium, which have the above beneficial effects.

    本发明公开了一种车辆控制器的唤醒方法,包括:当控制器进行上电处理时,进行SPI初始化处理;当SPI初始化处理完成时,判断中断状态寄存器中的中断标志是否为上电复位;若是,则通过读取的自检结果数据执行自检操作;若否,则通过输入状态比较寄存器的数据执行唤醒源识别流程;当所述自检操作或所述唤醒源识别流程执行完成时,配置开关量采集芯片;基于所述开关量采集芯片进行开关量监控,以实现车辆控制器的唤醒。以降低车辆的控制器在唤醒过程中的复杂度,提高控制器的硬件资源的利用率。本发明还公开了一种车辆控制器的唤醒装置、控制设备以及计算机可读存储介质,具有以上有益效果。
