An active vehicle height control method may include securing a road surface profile for unevenness of a road ahead of a vehicle and forming a target vehicle height profile by filtering the road surface profile. In addition, a controller is configured to form a disturbance profile using the road surface profile and the target vehicle height profile. The controller estimates vehicle behavior for the disturbance profile. Furthermore, the controller determines an inverse-phase control force that minimizes the estimated vehicle behavior, and drives an actuator using the inverse-phase control force to adjust a height of the vehicle.

A method for controlling a pitch of a vehicle, in which a control unit of a vehicle controls actuators of a suspension of a vehicle, which set a pitch of the vehicle, in dependence on a slope of a roadway section of a route of the vehicle and also a control unit and a vehicle.

A suspension joining structure may include a lower arm which has one end portion fastened to a vehicle body, an assist knuckle on which a strut portion is located, a fastening unit which is configured so that a second end portion of the lower arm and a lower end portion of the assist knuckle are fastened, a revoknuckle which is pivotally fastened to the assist knuckle to be rotated independently of the assist knuckle to perform the steering of a wheel, and a steering input portion fastened to the revoknuckle and configured to apply a steering force to the revoknuckle upon the steering of the wheel.

The present invention relates generally to motorized vehicles and more specifically to a three wheeled motorized vehicle providing a hybrid crossover between an automobile and a motorcycle that is able to take tight corners like a motorcycle by provision of a segment enclosing the operator that can lean into turns, The front segment contains two wheels for both steering and propulsion and is conventionally constructed like any typical front wheel drive vehicle. The rear segment contains the operator (and optionally passenger) supported on a single wheel, The two segments are joined together via a coupling that both supports the assembly and allows rotation of the rear segment about the longitudinal axis to perform the lean for operator and or passenger comfort, while transmitting critical control functions.

A vibration damping control apparatus for a vehicle executes preview vibration damping control while obtaining, from preview reference data, a road surface displacement related value relating to a vertical displacement of a road surface at a predicted passage position of a wheel of the vehicle. In the preview reference data, relationships are established among the road surface displacement related value obtained when a measurement vehicle actually traveled on the road surface, position information representing the position of a wheel of the measurement vehicle when the road surface displacement related value was obtained, and speed information representing the speed of the measurement vehicle when the road surface displacement related value was obtained or representing a speed range in which the speed of the measurement vehicle is contained.
