Transducers or subsystems are isolated and indicated as the source of diagnosed low system performance to facilitate fault treatment procedures. Active brake control system authority is automatically reduced for at least the duration of diagnosed fault conditions.Field of SearchActive circuit testingWith failure responsive means Electronic or electric component (e.g., speed detector, failure sensing) with warning With yaw control With yaw control With four wheel drive or all wheel drive From speed sensors From split coefficient of friction (mu) Electric control circuit detail ELECTRIC CONTROL WITH MEANS FOR DETECTING WHEEL SLIP DURING VEHICLE ACCELERATION AND CONTROLLING IT BY REDUCING APPLICATION OF POWER TO WHEEL | |
