Fig. 2 Rotary Height Sensor:
A fully independent rear suspension is used, consisting of MacPherson struts with integral air springs and dual-damping shock absorbers, counterbalancing torsion springs and a height sensor.
The air suspension and dual damping functions are controlled by a microcomputer based module which receives inputs for vehicle speed, door switch position, damping actuator feedback, steering wheel turning rate and angle, engine vacuum, throttle position, brake actuation, ignition switching, and vehicle ride height. The dual-damping function automatically switches from a soft to firm ride when the driving situation (hard cornering, acceleration or braking, etc.) dictates the need for increased damping effect.
The rear struts use a dual path mount which separates the strut and air spring mounting surfaces, to help provide for maximum isolation. The counterbalancing torsion springs, fitted between the strut and lower control arm, produce an outward force on the strut that tends to offset the binding forces induced by the rear wheels. The rotary design Hall effect type height sensor permits multiple height positions to be defined, resulting in specialized leveling during all types of driving and load characteristics.
