The desired speed of the motor/generator 22 can be predicted by comparing a trajectory based on present and past vehicle speed and acceleration, or an accelerator pedal position of the vehicle, and judging whether the vehicle is in a speed control mode or not. Another control can be added to this system, such as an end control during operation of a brake of the vehicle.
