The following describes in detail the technical solution proposed in the embodiments of the present application through the accompanying drawings.
The embodiment of the application provides a whole vehicle power management method applied to a commercial vehicle, as shown in fig. 1, the method provided by the embodiment of the application mainly comprises the following steps:
step 110, when a preset action command is triggered, acquiring the power state of the current whole vehicle power supply.

The power states include OFF, ACC, IGNON (Engine on/off), and craking, which are common knowledge in the art and are not described herein.
Step 120, when the power state is the OFF state, acquiring the state of the PEPS ECU in the PEPS controller of the whole vehicle; determining an executed wake-up program based on the state of the PEPS ECU to wake up the PEPS ECU; after the PEPS ECU is awakened, the electromagnetic power supply main switch is controlled to be continuously closed.
It should be noted that, the PEPS ECU (Electronic Control Unit electronic control unit) is an electronic control unit, is a core component of the PEPS controller, and is common knowledge in the art, and is not described herein in detail. The states of the PEPS ECU include a dormant state and an unsecured state.
The determining, based on the state of the PEPS ECU, an executed wake-up procedure to wake up the PEPS ECU may specifically be:
when the state of the PEPS ECU is in a dormant state, an opening request is sent to the electromagnetic power supply main switch through the vehicle body control module BCM so as to control the electromagnetic power supply main switch to be attracted, and then the PEPS ECU is awakened; when the state of the PEPS ECU is not in a dormant state, an opening request is sent to the electromagnetic power supply main switch through a vehicle body control module BCM (Body Control Module vehicle body control module) so as to control the electromagnetic power supply main switch to keep on, so that the PEPS ECU is continuously awakened.
And 130, after the power-on instruction is not received by the body control module BCM within the preset waiting time, sending a disconnection request to the PEPS controller through the body control module BCM so that the PEPS controller disconnects the electromagnetic power supply main switch after receiving the request.
After having the PEPS controller turn off the electromagnetic mains switch upon request, the method further comprises: and determining whether the PEPS controller is dormant or not according to the network state of the whole vehicle.
It should be noted that, specifically, when a key signal, a hard-wire signal is turned off, or a wake-on-network signal is turned off, the PEPS controller requests the Drive Control Unit (DCU) to leave the operation mode and reduce power. The PEPS controller then requests the DC/DC to leave the operational mode and then requests the BMS to open the high voltage relay. After the BMS finishes responding, the PEPS controller disconnects the high-voltage interlocking loop and the low-voltage relay, and each node enters a power-down dormancy process. The BMS judges whether to enter a dormant state according to the current and voltage conditions of the bus, and if the current of the bus is smaller than a certain current, the main positive relay and the main negative relay are disconnected successively. When the voltage drops to a certain preset value, the BMS feeds back a power-down instruction to the PEPS controller and enters a power-down Afterrun state. Finally, after the BMS sends the power-down completion instruction, the BMS enters a dormant state after a period of time.
In addition, fig. 2 is a schematic diagram of a whole vehicle power management system applied to a commercial vehicle according to an embodiment of the present application. As shown in fig. 2, the system provided in the embodiment of the present application mainly includes:
