Energy management system for a motor vehicle

摘要

The invention relates to an energy management system for a motor vehicle. The energy management system includes a first autonomous energy subsystem which requires energy to execute functions thereof and preferably includes separate energy submanagement; a second autonomous energy subsystem which requires energy to execute functions and favorably includes separate energy subsystems; and an energy management device used for perform upper-level energy management on the first and second energy subsystems. The first energy subsystem transmits information including at least one item related with management to the energy management device, and the second energy subsystem transmits information including at least one item related with management. The energy management device is implemented to, in accordance with the information related with management, determine running requirements of the first energy subsystem and transmit to the first energy subsystem, and determine running requirements of the second energy subsystem and transmit to the second energy subsystem. The invention also relates to a corresponding running method.
