Abstract
An engine drive torque is distributed to an extra wheel at a predetermined distribution ratio. When the vehicle makes a turn at low speed and when the torque distribution ratio to the extra drive wheel is high, a torsion is produced in the vehicle body, suspension and tires, etc., due to a rotation radius difference between the main and extra drive wheels. After the vehicle has stopped, and the engine is stopped, torque is no longer distributed to the extra drive wheel, the torsion is suddenly released and the vehicle vibrates. According to this invention, the release of torsion is performed gradually by decreasing the torque distribution ratio when the vehicle has stopped, with the engine still running in order to prevent this vibration.
