An electrically powered suspension system includes: an actuator that is provided between a vehicle body and a wheel of a vehicle and generates a load for damping vibration of the vehicle body; an information acquisition part that acquires information on a sprung state amount and a road surface state; a target load calculation part that calculates a first target load related to skyhook control based on the sprung state amount and calculates a second target load related to preview control based on the road surface state; and a load control part. The target load calculation part calculates a third target load related to roll generation control based on a target roll angle and calculates a combined target load into which the first target load, second target load, and third target load have been combined. The load control part performs load control of the actuator using the combined target load.

Provided is an electric suspension device including an electromagnetic actuator that is provided between a body and wheel of a vehicle and generates damping force for damping vibration of the body. It includes: an information acquisition unit that acquires information on a sprung speed and sprung acceleration of the vehicle; a bounce target value computation unit that computes a bounce target value for controlling the vehicle's bounce orientation based on the sprung speed; and a driving control unit that controls driving of the actuator with a control target load which is based on the bounce target value. The bounce target value computation unit has a bounce target load map in which the bounce target value is associated with the sprung speed. The bounce target value computation unit adjusts a width of a dead zone set in the map based on the information on the sprung speed and sprung acceleration.

An electromechanical vehicle height adjustment unit comprises an upper spring pad operative to support an upper end of a vehicle spring, a top mount that is displaceable relative to the upper spring pad, and a displacement mechanism coupled to the upper spring pad and the top mount and operative to displace the top mount relative to the upper spring pad in a height direction. The displacement mechanism comprises a rotary-to-linear motion conversion mechanism and an electric motor.

An electromechanical vehicle height adjustment unit comprises a control arm, a lower spring pad operative to support a lower end of a vehicle spring, and a displacement mechanism supported on the control arm. At least a portion of the displacement mechanism is integrated into the control arm. The displacement mechanism is coupled to the lower spring pad and is operative to displace the lower spring pad relative to the control arm. The displacement mechanism comprises a rotary-to-linear motion conversion mechanism and an electric motor.

A suspension system for a vehicle includes at least two torsion bars, each of which are connected on their first end to respective wheel suspensions that are arranged on opposite lateral sides of the vehicle. Movement of the wheel suspensions produces torque in the respective torsion bars. Each of the torsion bars are connected on their second ends to a frame of the vehicle through a damper system. Movement of the wheel suspensions produces torque in the respective torsion bar. The damper system selectively applies resistance to the torque in the torsion bars to selectively provide active variable spring rates to the wheel suspension, which application of resistance may be coordinated amongst the various torsion bars to inhibit roll of the vehicle during a turning maneuver or to increase occupant comfort when the vehicle encounters a bump or hole.

A method for detecting a malfunction of a component of a motor vehicle and/or a state change of the motor vehicle. The motor vehicle has a plurality of wheels, a plurality of active wheel suspension systems, a plurality of sensors, a control unit, an evaluation unit and a body, wherein the wheels are each fastened to the body via one of the active wheel suspension systems. The sensors capture sensor information which is used by the control unit to control the active wheel suspension systems. The sensor information is likewise used by the evaluation unit to detect the malfunction and/or the state change.

A damper control method for a vehicle may achieve normal control of dampers by maintaining the ride comfort enhancement effect of the ECS while reducing manufacturing costs in accordance with a reduction in the number of sensors through elimination of wheel G-sensors.

A rough road detection system is disclosed. The system includes a sensor data receiver to receive sensor data from one or more sensors monitoring a vehicle. A sensor data evaluator to: identify a repeating pattern in the sensor data, the repeating pattern indicative of a terrain type being traversed by the vehicle, determine a value of the repeating pattern, obtain a present set of operational values for at least one damping characteristic of an active valve damper coupled with the vehicle, and modify the present set of operational values for the at least one damping characteristic of the active valve damper based on the value of the repeating pattern to develop a modified set of operational values for the at least one damping characteristic of the active valve damper.

An omnidirectional moving device is provided with a vehicle chassis, a vehicle body, a universal coupling, and an attitude stabilizing system. In the vehicle chassis, a plurality of wheels that are capable of moving omnidirectionally are provided. The vehicle body is mounted on the vehicle chassis. The universal coupling connects the vehicle chassis to the vehicle body, and the attitude of the vehicle body relative to the vehicle chassis can be changed via this universal coupling. The attitude stabilizing system causes the vehicle chassis to move in a direction that corresponds to a change in the attitude of the vehicle body, and maintains the attitude stability of the vehicle body.

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.
