The front wheel-side target movement amount determination unit decreases, a movement amount of the front wheel-side support member as the estimated weight increases.

Abstract: In a vehicle height adjustment device, an operation amount of an actuator increases in accordance with supplied current, a detector detects a vehicle height, and a changer changes the vehicle height in accordance with the operation amount of the actuator. The changer shifts to a vehicle height increasing state or to a vehicle height decreasing state based on whether the operation amount is not higher than a predetermined amount. A controller controls the current supplied to the actuator to make the relative position have a target value. The controller determines a target current supplied to the actuator based on a control map that correlates a deviation between the target value of the relative position and a detection value to the target current.

Abstract: A vehicle height adjustment device includes an actuator, a detector, and a controller. The actuator is driven when supplied with a current and is configured to change a relative position of a body of a vehicle relative to an axle of a wheel of the vehicle. The detector is configured to detect the relative position. The controller is configured to control the current supplied to the actuator to make the relative position a target value so as to adjust a vehicle height of the body. When a detection value of the detector is smaller than the target value of the relative position, the controller is configured to alternately supply an increase current and a maintenance current to the actuator. The increase current increases the relative position to increase the vehicle height. The maintenance current maintains the relative position to maintain the vehicle height.

Abstract: A vehicle height adjustment apparatus adjusts a vehicle height by changing a front distance that is a distance in a longitudinal direction of the front fork between a body of a vehicle and a front wheel of the vehicle, and by changing a rear distance that is a distance in a longitudinal direction of the rear suspension between the body of the vehicle and a rear wheel of the vehicle. In this apparatus, the posture of the vehicle body is not affected even when the vehicle height is adjusted (i.e., raised), providing the vehicle with further stability during driving.
