Abstract:
An apparatus for a cab over type truck, comprising:a plurality of shock absorbers, each shock absorber being 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 its corresponding shock absorber in response to an input control signal;a first detector for detecting a behavior of the vehicle cab and for developing a signal indicative of the behavior of the vehicle cab;a basic damping force characteristic controller for developing the control signal to control the damping force characteristic of each shock absorber via the corresponding damping force characteristic varying member on the basis of the vehicle cab behavior indicative signal developed by the first detector;a second detector for detecting a behavior of a vehicle trailer of the cab over type truck hauled by the vehicle chassis and for developing a signal indicative of the behavior of the vehicle trailer; anda corrective controller for modifying a value of the control signal developed by the basic damping force characteristic controller so as to correct the control of the damping force characteristic carried out by the basic damping force characteristic controller on the basis of the vehicle trailer behavior indicative signal.
