Control system and method for operating adjustable vehicular suspension unit.

摘要

A system for measuring ride height and relative vertical velocity of a motor vehicle suspension includes a sensor (10) for detecting vertical motion of a wheel and tire assembly (12) which is relatively movable with respect to the chassis (20) of the motor vehicle and a processor (32) operatively connected with the sensor (10) for calculating the relative velocity of the suspension with respect to the chassis. The processor (32) includes a mechanism for comparing the magnitude of the calculated velocity of the road wheel with a set of threshold velocity values and output circuits for producing a control signal in the event that the calculated velocity lies between two of the threshold values. The system also includes an adjustment mechanism (60) operatively connected with the processor and responsive to control signals therefrom for adjusting an adjustable suspension unit.
