Abstract
A vehicle height adjusting device includes a front fork and a rear suspension capable of changing the relative position between a vehicle body and wheels of a vehicle, and a control device that adjusts a vehicle height, which is a height of the vehicle body, by controlling the front fork and the rear suspension to change the relative position. The control device changes a vehicle height change rate, which is a rate of changing the vehicle height to a target vehicle height during stoppage, on the basis of deceleration of the vehicle.
Claims6
A vehicle height adjusting device, comprising:
- a changing unit capable of changing a relative position between a vehicle body of a vehicle and wheels of the vehicle;
- and
- a control unit that adjusts a vehicle height, which is a height of the vehicle body, by controlling the changing unit to change the relative position,
- wherein the control unit changes a vehicle height change rate, which is a rate of changing the vehicle height to a target vehicle height during stoppage, on the basis of deceleration of the vehicle, estimates an estimated stopping time on the basis of the vehicle speed and the deceleration of the vehicle, and changes the vehicle height change rate on the basis of a vehicle height lowering completion time which is obtained by adding or subtracting a certain time to or from the estimated stopping time.
