Dormancy control method, T-BOX and computer readable storage medium

The invention discloses a dormancy control method, a T-BOX and a computer readable storage medium. The dormancy control method comprises the steps: when monitoring that a whole vehicle is powered off, determining whether the T-BOX satisfies a dormancy condition; if yes, notifying each service module to sleep, controlling to disconnect the MCU from the remote service platform, and controlling the MCU to perform RTC periodic wake-up operation, so that the T-Box enters a low-power-consumption sleep mode; when the T-Box is in the low-power-consumption sleep mode and does not detect the power-on event of the whole vehicle within a preset time period, controlling the power supply chip to be closed through the MCU so as to enable the T-Box to enter an ultra-low-power-consumption sleep mode. According to the method and the device, the dormancy logic of the T-Box in different modes is formulated, so that the phenomenon that the T-BOX does not sleep after the whole vehicle is powered off, so that the power failure of t
