[0152] Among them, √ means that under this energy management mode, the power-consuming equipment is powered, [] means that under this energy management mode, the power-consuming equipment can choose whether to be powered, and blank means that under this energy management mode, the power-consuming equipment is not powered.

[0153] In this embodiment, more detailed and specialized status information is obtained through the body subsystem, power subsystem, cockpit subsystem and network subsystem, so that the current state and demand of the vehicle can be more accurately judged through the status information of multiple subsystems, and more refined and intelligent energy management can be provided. Compared with the traditional single state judgment method, the vehicle working mode can be divided based on the status information of multiple subsystems, so that the vehicle corresponds strongly to the actual driving scene, and based on the actual needs of the actual driving scene, the vehicle electrical equipment can be accurately managed and the distribution network managed, so that the vehicle energy management has higher accuracy, improves the system coordination of the vehicle, and improves the user's driving experience. In addition, it can be understood that if the division of the vehicle working mode is not accurate enough, it will lead to abnormal energy management, which will affect the user experience and even vehicle safety. Therefore, through the vehicle management method provided in this embodiment, the current vehicle working mode can be more accurately judged according to the data of each system interface of the current vehicle, and the vehicle energy management mode can be more accurately defined. Therefore, energy management can be more accurately performed and power supply control can be performed on electrical equipment. In addition, since the system is designed in a modular manner, each subsystem is decoupled from the vehicle working mode judgment module. In this way, the adjustment of each subsystem only requires changing the corresponding system interface, which will not affect the vehicle working mode judgment. Therefore, the vehicle management method is more applicable and can be applied to a wider range of vehicle models. At the same time, due to the modularization, it is easier to develop customized scenarios.
