Vehicle power domain control system and electric vehicle

The invention provides a vehicle power domain control system and an electric vehicle, and the vehicle power domain control system comprises a power conversion module, a power domain control module and a motor driving module. The power supply conversion module is used for receiving a first voltage provided by the power battery, processing the first voltage and then respectively supplying power to the first load and the second load; the power domain control module is used for responding to a vehicle control instruction and generating a corresponding control signal according to the vehicle control instruction; the motor driving module is connected between the power domain control module and a driving motor and is used for generating a corresponding driving signal according to the power and the control signal output by the controller and driving the driving motor to work based on the driving signal so as to convert electric energy provided by the power battery into mechanical energy for driving the electric vehic
