PURPOSE:To improve stability of vehicle height and adjust the vehicle height in a shoft time according to circumstances, by transmitting a control command to a drive system only when a monitoring time continues, and starting to drive a suspension mechanism. CONSTITUTION:A drive system 46 includes an oil pressure source 47, selector valves 48 and 49, and an oil tank 50. The selector valves 48 and 49 and a motor 21 are controlled by a control device 60. The control device 60 is connected to a vehicle height sensor 61, speed sensor 62, steering sensor 63, brake sensor 64, acceleration sensor 65, parking brake sensor 66 and vehicle height setting switch device 70. While a vehicle height signal is normally input from the sensor 61 to the control device 60, an average of vehicle heights is calculated in the control device every fixed time. The average is compared with a vehicle height set value which is previously set by the device 70. According to magnitude of a permissible range as the comparative result, a control command for instructing elevation and lowering of the vehicle is generated. |
