ABSTRACT:
A detector22detects action forces acting on a wheel5provided to a vehicle. An estimator21aestimates the present value of a vehicle mass m on the basis of an action force acting in a component force direction out of the action forces, and an acceleration of the vehicle in the component force direction. Specifically, the estimator21aestimates the present value of the vehicle mass m on the basis of an acceleration ax in the longitudinal direction and a longitudinal force Fx or on the basis of an acceleration ay in the lateral direction and a lateral force Fy. The estimator estimates the present value of a center-of-gravity height of the vehicle on the basis of the detected variation amount of the vertical force and the detected longitudinal force.
