The invention discloses a starting power supply management system and a vehicle. The starting power supply management system comprises a microcontroller and a watchdog timer, the microcontroller comprises a reset end, the watchdog timer comprises a reset control end, and the watchdog timer is connected with the microcontroller through the reset control end and the reset end; the watchdog timer is used for periodically receiving a clock signal of the microcontroller and sending a reset control signal when the clock signal of the microcontroller is still not received when counting overflows; the microcontroller is used for resetting in response to the reset control signal. The system can control the microcontroller to reset in time when the microcontroller flies or crashes, so that the reliability and safety of starting the power supply management system are improved.
本发明公开了一种启动电源管理系统和车辆,启动电源管理系统包括:微控制器和看门狗定时器;微控制器包括复位端,看门狗定时器包括复位控制端,看门狗定时器通过复位控制端和复位端与微控制器连接;看门狗定时器用于周期性地接收微控制器的时钟信号,并且在计数溢出仍未接收到微控制器的时钟信号时发送复位控制信号;微控制器用于响应于复位控制信号进行复位。该系统可以在微控制器跑飞或死机时,及时控制微控制器复位,提高启动电源管理系统的可靠性及安全性。
