    Abstract: A vehicle control device includes a sensor and a controller. The sensor detects wheel speed. The controller estimates an amount of pitch motion made by a vehicle based on information in a prescribed frequency range of wheel speed detected by the sensor. The controller control friction brakes so as to bring the pitch motion amount to a target pitch motion amount, as well as gradually lowering an amount by which the friction brakes are controlled, in instances where an estimation accuracy of the pitch motion amount deteriorates.

    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.
