Abstract
A fail-safe control unit for a vehicle having a first control system for controlling a steer angle and a second control system for controlling a condition of the vehicle, such as a driving force distribution in a 4WD system, or a damping characteristic of a suspension system. When one of the first and second control systems becomes abnormal, and the other remains normal, the fail-safe control unit adjusts the normal control system so as to maintain or improve the directional stability of the vehicle notwithstanding the failure of the abnormal system.
