SUSPENSION CONTROL: AIR SUSPENSION SYSTEM (w/o AVS): SYSTEM DESCRIPTION

SYSTEM DESCRIPTION

1. REAR AIR SUSPENSION SYSTEM DESCRIPTION

- This system uses pneumatic cylinders instead of the coil springs that are used in a conventional rear suspension. The suspension control ECU analyzes the information based on the switches, sensors, and input signals, operates the compressor assembly, and uses the solenoid valves to control the vehicle height.
- The suspension control ECU detects, via the height control sensor, the changes in the rear vehicle height that results from the number of occupants or the amount of the load. Then, the suspension control ECU controls the height control solenoid valves and the compressor assembly in order to automatically adjust the rear vehicle height to a constant (normal) vehicle height.
- Furthermore, three vehicle heights can be selected by operating the height control switch: HI, NORMAL, and LO. The HI vehicle height ensures performance on rough roads. The LO vehicle height facilitates the entry and exit of the occupants and the loading and unloading of cargo. The NORMAL vehicle height helps realize excellent controllability and riding comfort during normal driving.
