A damping control system for a vehicle having a suspension located between a plurality of ground engaging members and a vehicle frame are disclosed. The vehicle including at least one adjustable shock absorber having an adjustable damping characteristic.

An automatic tilting vehicle comprises left and right front wheels and a rear wheel. A control unit controls a vehicle tilting device so that the tilt angle of the vehicle becomes the target tilt angle. The control device is configured to swingingly vibrates the vehicle in the lateral direction by tilting the vehicle by the vehicle tilting device, to estimate a height of the center of gravity of the vehicle based on a resonance period of swinging vibration of the vehicle, and to correct the target tilt angle such that a perpendicular passing through the estimated center of gravity passes within a range of a triangle formed by connecting grounding points of the left and right front wheels and a grounding point of the rear wheel.

An object of the present invention is to obtain an electromagnetic suspension apparatus capable of meeting a request to improve ride comfort irrespective of a magnitude of a spring constant preset in a spring member. The electromagnetic suspension apparatus includes an electromagnetic actuator that generates a driving force related to vibration damping of the vehicle body, an information acquisition unit that acquires information on a stroke position of the electromagnetic actuator, and an ECU that calculates a target driving force of the electromagnetic actuator and controls a driving force of the electromagnetic actuator using the calculated target driving force. When the stroke position acquired by the information acquisition unit is in a neutral range including a neutral position, the ECU corrects the target driving force so as to reduce a spring force related to the spring member as compared with when the stroke position is in a non-neutral range.

A three-wheeled vehicle having a frame with articulated four-link straight line linkage mechanism mounted thereon, said mechanism including lateral arms arranged symmetrically about the axis of symmetry of the vehicle, and also one conditionally front wheel, and two conditionally rear wheels, each having an axis. The articulated four-link straight line linkage mechanism also includes a linear steering mechanism, a T-shaped arm, a short central arm, an O-shaped bracket, a rubber-strand torsion member of the conditionally front wheel, and one rubber-strand torsion member and L-shaped wheel arm per each conditionally rear wheel, which form a rear axle connected to the linear steering mechanism via the T-shaped linkage arm. The result is increased stability when cornering at a speed, and more accurate steering.

A vehicle of the present disclosure may include at least one pair of opposing wheels coupled to a tiltable central chassis by a four-bar linkage or the like, such that the wheels are configured to tilt in unison with the central chassis. A steering actuator and/or a tilting actuator may be discretely controllable by an electronic controller of the vehicle. The controller may include processing logic configured to maintain alignment between a median plane of the chassis and a net force vector caused by gravity and any induced centrifugal forces. Various control algorithms may be utilized to steer the vehicle along a desired path, either autonomously or semi-autonomously.

A damping control system for a vehicle having a suspension located between a plurality of ground engaging members and a vehicle frame includes at least one adjustable shock absorber having an adjustable damping profile.
