The invention provides a vehicle-mounted MCU starting method and system.The method comprises the steps that when it is detected that a vehicle is powered on in real time, a starting signal is sent to a vehicle-mounted MCU in the vehicle, and an HSM module corresponding to the vehicle-mounted MCU is synchronously started; initial starting parameters corresponding to the vehicle-mounted MCU are detected in real time, and an MAC value corresponding to the vehicle-mounted MCU is calculated in real time through an HSM module according to the initial starting parameters; judging whether the MAC value is smaller than a preset MAC threshold value or not in real time; if it is judged that the MAC value is smaller than the preset MAC threshold value in real time, it is judged that the vehicle-mounted MCU meets the starting condition, the vehicle-mounted MCU is started immediately, and the MAC value is a specific numerical value. According to the invention, the starting time of the vehicle-mounted MCU can be greatly shortened, and the user experience is correspondingly improved.

    本发明提供了一种车载MCU启动方法及系统,该方法包括:当实时检测到车辆上电时,向车辆内部的车载MCU发送启动信号,并同步启用与车载MCU对应的HSM模块;实时检测出与车载MCU对应的初始启动参数,并通过HSM模块根据初始启动参数实时计算出与车载MCU对应的MAC值;实时判断MAC值是否小于预设MAC阈值;若实时判断到MAC值小于预设MAC阈值,则判定车载MCU满足启动条件,并立即启动车载MCU,MAC值为具体的数值。本发明能够大幅缩短车载MCU的启动时间,对应提升了用户的使用体验。
