Pitching-suppressive control system and method for an automotive vehicle suspension
Patent
·
OSTI ID:5927174
A damper control system is described for an automotive vehicle suspension having a damping characteristic comprising: first means, interposed between a sprung mass and an unsprung mass of the vehicle, for producing a damping force resisting relative displacement of the sprung mass and the unsprung mass; a braking condition detector for producing a binary braking state indicative signal pulse having a leading edge and a trailing edge, the pulse extending as long as a vehicle brake is applied; an actuator for operating the first means between a first and a second position to change the damping characteristics of the suspension to produce a higher damping force in the first position, and to produce a lower damping force in the second position; and a controller connected with the actuator and the braking condition detector to operate the actuator at the first position in response to each of the leasing and trailing edges of the braking state indicative signal pulse. A method is also described of controlling a damper or dampers of a vehicle suspension system.
