Abstract:
1. A control system for an electric driving system for a vehicle, comprising: an inverter for converting a DC electrical power output from a storage device capable of electrical charge and discharge of electric power into AC electrical power; and an AC electric motor, driven by the AC electrical power output from said inverter for generating electrical driving force for driving a component to be driven, wherein said control system for an electric driving system controls driving of said AC electric motor by controlling said inverter according to an instructed torque for said AC electric motor, and wherein, with said storage device at or near a state of full, the electrical power output of said AC electric motor becomes negative, excess electrical energy is generated, and said control system controls the current applied to said AC electric motor such that the loss in said AC electric motor exceeds the negative electrical power output of said AC electric motor.
