Abstract
A vehicle suspension includes a variable damping effectiveness type shock absorber, which has an actuator and according to selective actuation thereof can be set to first, second, or third conditions which respectively cause the shock absorber to provide minimum, medium, or maximum damping effect. A control system for this suspension includes: a means for detecting one or more parameters relating to the operational condition of the vehicle and for outputting information signals representative thereof; a means for being manually controlled by an operator and for selecting between first manual, second manual, and auto operational modes; and a control means for: when the manual selecting means is selecting the first manual mode, actuating the actuator to its first condition; when the manual selecting means is selecting the second manual mode, actuating the actuator to its second condition; and, when the manual selecting means is selecting the auto operational mode, actuating the actuator to one of a set of its conditions including its first condition and its third condition according to the information signals outputted by the detecting means. The vehicle operational parameters may in…
