ABSTRACT:
A vehicle suspension apparatus has a hard/soft switching unit for switching suspension units between a hard state and a soft state, a vehicle velocity sensor for detecting a vehicle's velocity, and control means for receiving a signal from the vehicle velocity sensor and controlling the hard/soft switching unit for holding the suspension units in the soft state when the vehicle's velocity detected by the vehicle velocity sensor is smaller than a switching velocity as a first preset velocity set by the hard/soft switching unit and in the hard state when the vehicle's velocity detected by the vehicle velocity sensor exceeds the switching velocity. The vehicle suspension apparatus further has a switching velocity preset switch for presetting the switching velocity. The control means controls the hard/soft switching unit so as to set the suspension units in the hard state and to store the vehicle's velocity detected by the vehicle velocity sensor as a subsequent switching velocity when the switching velocity preset switch is operated while the vehicle's velocity detected by the vehicle velocity sensor falls between the first preset velocity and a second preset velocity lower than the first preset velocity and the suspension units are set in the soft state.
