Abstract
A vehicle suspension apparatus has air spring chamber provided at a suspension unit for supporting a rear wheel, air supply means for supplying air to the air spring chamber of the suspension unit for supporting the rear wheel through supply opening and closing valve, air exhaust means for exhausting air from the air spring means of the suspension unit for supporting the rear wheel, a parking brake sensor for detecting the operated state of a parking brake, and a shift position detecting sensor for detecting the shift position of an automatic transmission having a fluid drive unit for transmitting drive power to wheels. The parking brake sensor detects whether or not the parking brake is engaged. The shift position detecting sensor detects whether or not the shift position of the automatic transmission is operated from any of parking position (P) and neutral position (N) to running position (D, L, 2) to raise the vehicle height of the rear wheel side to supply air to the air spring chamber of the rear wheel side. The fact that the shifting position of the automatic transmission is operated from either the parking position (P) or the neutral position (N) to the running position (R) is detected to exhaust air from the air spring chamber of the rear wheel side to lower the vehicle height of the rear wheel.
