Abstract
A vehicle control device includes a wheel speed sensor and a controller. The wheel speed sensor detects wheel speed. The controller estimates a sprung mass state based on information in a predetermined frequency region of wheel speed and controls an actuator to bring the estimated sprung mass state to a target sprung mass state. The controller calculates a first wheel speed as a reference wheel speed for individual wheels. The controller calculates a second wheel speed as a reference wheel speed of front and rear wheels. The controller calculates a third wheel speed as a reference wheel speed of all wheels. The controller calculates a reference wheel speed of each wheel. The controller detects that the estimation accuracy has deteriorated when a differential among reference wheel speeds of the wheels is equal to or greater than a prescribed value.
