All wheel drive vehicles with in-wheel motors can control the yaw-moment of the vehicle by utilizing force distribution. When the power output of the in-wheel motor stops or the rotation clings, the vehicle becomes unstable by the unbalance of the right and left driving forces. The yaw rate and the lateral acceleration were measured when the motor broke down using an electric vehicle with in-wheel motors on all of its wheels. Not small influence was occurred on the test when the motor breaks down while accelerating. It was effective to stop the motor power output on the same axle when one of the motor broke down, Even if one motor were to break down, the control algorithm with high redundancy and safety features makes possible for the vehicle to keep running using the other motors.
