Pitching-suppressive control system and method for an automotive vehicle suspension
Abstract
An automotive vehicle suspension has a damper (14) with variable damping characteristics, specifically adjustable damping force. A controller (100) responds to application and release of vehicle brakes by increasing the damping force. Increasing the damping force at the beginning of braking suppresses nose-dive of the vehicle. On the other hand, increasing the damping force at the end of braking suppresses pitching motion of the vehicle. This greatly improves the behavior of the vehicle sprung mass during braking.
