Abstract

A vehicle control method is provided for controlling a vehicle having a friction clutch configured to switch between engagement and disengagement between a motor/generator and a drive wheel. The vehicle control method includes maintaining a friction clutch disengaged with slack eliminated in a stroke while the vehicle is stopped, reducing a motor rotational speed using a predetermined rotational speed as a target motor rotational speed in response a request to stop a motor/generator upon determining the motor rotational speed of the motor/generator is greater than the predetermined rotational speed, and when the motor rotational speed has reached the predetermined rotational speed, reducing the motor rotational speed toward zero while limiting the torque of the motor/generator.
