Abstract
An apparatus for a cab over type truck, comprising: a) at least one shock absorber interposed between a vehicle cab of the truck and a vehicle chassis of the truck and having a damping force characteristic varying member arranged so as to enable a variation in the damping force characteristic of the shock absorber in response to a control signal; b) a vertical behavior sensor arranged on the vehicle chassis of the truck for detecting a vertical behavior on the chassis; and c) a control unit arranged for estimating the vertical behavior on the cab of the truck from the detected vertical behavior on the chassis, and providing a control signal for the shock absorber so as to control the damping force characteristic of the shock absorber on the basis of the estimated vertical behavior on the cab of the truck.
