Abstract:
1. A vehicle control device comprising: an actuator that performs sprung mass vibration damping control; a wheel speed sensor that detects wheel speed; a sprung mass state estimating unit that estimates a sprung mass state based on information in a prescribed frequency range of wheel speed detected by the wheel speed sensor; an actuator orientation control unit that controls the actuator so as to bring the estimated sprung mass state to a target sprung mass state; a reference wheel speed calculating unit including: an estimation accuracy deterioration detection unit that detects deterioration in accuracy at which estimating is performed by the sprung mass state estimating unit when a differential among reference wheel speeds of the wheels to the low-frequency side from the predetermined frequency region in which sprung mass behavior appears is equal to or greater than a prescribed value.
