Abstract: A method for controlling a vertical vibration damping of a wheel of a vehicle, in which the wheel has a suspension including a vibration damper with a control element including an actuating element for adapting a damping characteristic of the vibration damper includes a series of steps. The vehicle includes a first sensor for detecting roadway anomalies, a second sensor for detecting a vertical displacement of the wheel, and a control unit connected to the first and second sensors and the control element. The method steps include detecting roadway anomalies with the first sensor, detecting the vertical displacement with the second sensor and switching the vibration damper with the control element at a first point in time from a first state with a first damping characteristic into a second state with a second damping characteristic when a first sensor signal generated by the first sensor indicates a roadway anomaly with a minimum height.

Abstract: A system for damping control for a vehicle includes a parameter component and a damping adjustment component. The parameter component is configured to determine one or more driving parameters of a vehicle. The one or more driving parameters include a velocity of the vehicle. The damping adjustment component is configured to adjust damping of suspension of the vehicle during driving based on the one or more driving parameters. The damping adjustment component is also configured to adjust damping of suspension at a zero velocity for a threshold time period in response to transitioning from a non-zero velocity to the zero velocity.

Abstract: A suspension controller includes a wheel speed sensor that detects the wheel speed of each wheel, a basic input amount calculating unit that calculates the basic input amount of the vehicle on the basis of a wheel speed variation detected by the wheel speed sensor, a state amount calculating unit that calculates the state amount of the vehicle by inputting the basic input amount to a vehicle model representing the motion of the vehicle, and a damper controlling unit that controls the damping force of a damping-force-variable damper on the basis of the calculated state amount. If the wheel speed variation detected by the wheel speed sensor decreases below zero by a predetermined value or more on the minus side, the vertical load of the wheel is considered to be decreased, and the damping force is controlled to be greater than before the decrease.

Abstract: An active suspension system senses roadway defects and adjusts an active and controllable suspension system of the vehicle before tires come in contact with the defect. The active suspension system identifies a type of defect or debris, e.g., pothole, bump, object, etc., along with the size, width, depth, and/or height information of the defect to more accurately control operation of the suspension system to prepare for, or avoid contact with the roadway defects and obstacles. Imaging techniques are employed to identify the defect or debris. Operation of a serviced cruise control system is controlled to enhance passenger safety and comfort.

Abstract: The damper control device includes a three axis rate sensor that detects a pitching angular velocity of a vehicle body of a two-wheeled vehicle, a pressure sensor that detects a pressure of a contraction-side chamber in a front-wheel side damper, a pressure sensor that detects a pressure of a contraction-side chamber of a rear-wheel side damper, and a correction unit that corrects the pitching angular velocity. The damper control device controls the pressure of the contraction-side chamber in the front-wheel side damper and the pressure of the contraction-side chamber of the rear-wheel side damper on the basis of the corrected pitching angular velocity, the pressure of the contraction-side chamber in the front-wheel side damper and the pressure of the contraction-side chamber of the rear-wheel side damper.

Abstract: The present invention is a system for adjusting the height of vehicles. The vehicle is supported by a hollow cylinder and a piston having an undersized piston skirt is mounted on the suspension system's coil spring, and sealingly slidable within the cylinder bore. When a fluid is introduced into the expandable pressure space between the piston and the cylinder top, the piston and cylinder are forced apart, raising the vehicle. The undersized piston skirt can extend beyond the end of the cylinder, allowing the piston a greater travel length within the cylinder bore. The invention may be operated manually by a vehicle driver through push buttons, which can be the vehicle's existing cruise control buttons. Alternatively, the system can be automated using a control unit to automatically adjust ground clearance to avoid collision with obstacles in the vehicle's path. In another embodiment, the lift system, or any lift system, is prevented from activating, and deactivates (if previously activated) if the vehicle is travelling at excessive speed.

Abstract: A rollover prevention apparatus includes a primary hydraulic cylinder attached to a frame bracket, a secondary hydraulic cylinder attached to the primary hydraulic cylinder and a wheel bracket. The rollover prevention apparatus includes a stabilizing wheel affixed to the wheel bracket. The stabilizing wheel is substantially in line with a plurality of wheels affixed to the frame while the primary and secondary hydraulic cylinders are retracted, the line being substantially perpendicular to the primary and secondary hydraulic cylinders. The stabilizing wheel has a negative camber angle with respect to the plurality of wheels while the primary and secondary hydraulic cylinders are retracted. A rollover event may be averted by extending the primary and secondary hydraulic cylinders such that the stabilizing wheel makes contact with a road without substantially leaving a lane, and using the secondary hydraulic cylinder to push against the road until the rollover event has been averted.

Abstract: A suspension control apparatus includes a single-wheel model calculating unit that calculates a sprung speed and a stroke speed using a single-wheel model on the basis of a wheel speed variation detected by a wheel speed sensor and a damper control unit that controls the damping force of a variable damping force damper by setting a skyhook control target current and an unsprung vibration damping control target current of the variable damping force damper on the basis of the calculated sprung speed and stroke speed. When a slip determining unit determines that the wheel is in a slipping state based on deviation of a value detected by the wheel speed sensor from a wheel speed estimated by the vehicle body speed estimating unit by a predetermined value or more, the damper control unit suppresses skyhook and unsprung vibration damping control by fixing or gradually decreasing the control target currents.
