PROBLEM TO BE SOLVED: To provide a controller for a right-left drive force adjusting device for a vehicle, which controls the device in conformity with control regulations by eliminating influence of torque difference caused by moment of inertia. SOLUTION: When the rotation speed of a motor 16 is Nm, the rotation speed difference between right and left wheels is ΔN, moment of inertia of the motor 16 is I and the deceleration ratio G of the motor 16 is [Nm/ΔN], rotation speed difference angle acceleration dΔN obtained by differentiating the rotation speed difference ΔN is summed with the moment of inertia I and G2as the square of a deceleration ratio G to obtain a correction value of the torque difference [2G2×I×dΔN], a control output equivalent to the torque difference is obtained from a plurality of control regulations 1-M, the correction value is added to the control output to obtain a correction torque difference, and the motor 16 is controlled so that the correction torque difference is the obtained correction torque difference, thereby controlling the attitude of the vehicle.
