ELECTRONIC-CONTROLLED SUSPENSION (ECS)

While setting the spring constant and the damping coefficient to small values provide a car with good, soft riding comfort on well-paved roads, it causes poor road-holding characteristics on rough roads and large attitude variations during cornering, acceleration and deceleration. Moreover, it compromises the accident avoidance performance and the high speed directional stability. We have overcome these problems by developing the ELECTRONIC-CONTROLLED SUSPENSION (ECS) which normally responds softly but increases the spring constant and the damping coefficient automatically when running at high speed, cornering, accelerating or decelerating.
