Abstract
A vehicle is provided with an engine and a motor, which has driving and electric generating functions and which is directly connected to the engine as a vehicle propulsion system, an engine controller for controlling the operating condition of the engine, and a motor controller for controlling the driving and electric generating conditions of the motor based on the operating condition of the engine and the driving condition of the vehicle independently from the control of the engine made by the engine controller. The vehicle runs by only utilizing its engine by simplifying the control of the engine and motor, and by improving the reliability of the motor controller.
