The first relationship includes sum of right and left wheel torques, sum of right and left motor torques, sum of right and left wheel driving forces, or sum of right and left motor driving forces. The second relationship includes difference between right and left wheel torques, difference between right and left motor torques, difference between right and left wheel driving forces, or difference between right and left motor driving forces. The third relationship includes sum of left and right electric powers generated or consumed by the electric motors, respectively.
