Abstract

A wireless remote control radio-transmits a vehicle height adjusting signal tagged with a remote control identification code in order to improve vehicle height adjustment operability in a vehicle such as a truck. The remote control identification code is pre-registered in a receiver, which, upon receipt of the vehicle height adjusting signal tagged with the remote control identification code, takes in the vehicle height adjusting signal. According to information contained in the received vehicle height adjusting signal, an air suspension ECU controls the supply and discharge of compressed air for air springs to adjust the vehicle height. When an emergency operation switch is operated, the vehicle height adjusting signal from the wireless remote control is disabled, and vehicle height adjustment is preferentially made based on a switching signal from the emergency operation switch.
