Abstract: A control apparatus and method for a vehicle that has at least one detector that detects a running state of the vehicle, and a controller that receives a result of detection by the detector and controls a predetermined vehicle-installed apparatus. The controller determines whether the detector has failed; restricts a control process by which the controller controls the vehicle running state if it is determined that the detector has failed; detects a collision state of the vehicle; and restricts the determination that the detector has failed, for a predetermined time following detection of the collision state of the vehicle, if the collision state is detected.

Abstract: A wheel control state display apparatus of the present invention has a vehicle state detector for detecting a state of a vehicle, a traction-braking force controller for adjusting braking force or traction at a plurality of wheels mounted on the vehicle, based on the result of detection of the vehicle state detector, and a control state display for displaying a wheel under adjustment of the braking force or the traction by the traction-braking force controller. The apparatus according to the present invention can present the conditions of the vehicle to the driver in more detail by displaying which wheel is under the adjustment of the traction-braking force.
