Abstract
A suspension apparatus of a vehicle has a cylinder unit interposed between a sprang weight and an unsprung weight, which changes a ride height of the vehicle body by supplying or discharging an operating liquid through a supply/discharge control valve. The supply/discharge control value is controlled on the basis of a predetermined condition so as to control a posture of the vehicle body. There are further provided a bump detecting means for detecting a bump of each of the wheels and a pressure detecting means for detecting a pressure in the cylinder unit. When the bump is detected by the bump detecting sensor to be below a given value, if the pressure detected by the pressure detecting means is continued at a magnitude above a given value for a given period of time, it is judged that the supply/discharge control valve is in trouble.
