A vehicle-height adjusting device includes: a vehicle-height adjusting unit that adjusts a vehicle height through extension and contraction thereof, which is disposed between each wheel and a vehicle body of a vehicle; a control unit that controls actuation of the vehicle-height adjusting unit; an obstacle detecting unit that detects an obstacle that is present within a predetermined range from the vehicle; a steering-angle detecting unit that detects an steering angle of the vehicle; and an identification unit that identifies a portion of the vehicle that overlaps the obstacle, based on a detection result by the obstacle detecting unit and a detection result by the steering-angle detecting unit, in which the control unit controls at least one of the vehicle-height adjusting unit, based on an identification result of the identification unit.

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.

An active control system for vehicle suspensions includes a detection module which detects a vehicle running state and a front road condition by means of an advanced mode or a standard mode; a calculation module which comprehensively calculates, in combination with running data and dimensions of a vehicle and the front road condition data collected by the detection module and according to passenger comfort requirements, target data of adjustment; and an implementation module which adjusts a height of each suspension of the vehicle according to the target data obtained by the calculation module.

Left and right stabilizer bars are provided between left and right wheels of a vehicle. A control unit controls an actuator to control a rotation angle of the right stabilizer bar with respect to the left stabilizer bar. The control unit determines whether the vehicle is moving, whether a vehicle speed is less than a first threshold value, and whether a vehicle state is in transition from a moving state to a stopped state. A detection unit detects a control amount of the actuator. When the vehicle is moving, the vehicle speed is less than the first threshold value, the vehicle state is in transition from the moving state to the stopped state, and the control amount of the actuator is greater than zero, the control unit decreases the control amount of the actuator such that the control amount of the actuator becomes zero before the vehicle speed becomes zero.

An air management system for a vehicle having a first pneumatic circuit and a second pneumatic circuit, in which the first and second pneumatic circuits are pneumatically connected in a neutral position via a cross-flow mechanism. The first pneumatic circuit is configured to independently adjust air pressure of a first side of the vehicle. The second pneumatic circuit is configured to independently adjust air pressure of a second side of the vehicle. The system is configured to establish pneumatic communication between the first and second pneumatic circuits when the air management system is not independently adjusting the adjust air pressure of the first side of the vehicle and the air pressure of the second side of the vehicle in the cross-flow mode.

A damping force control device for controlling damping forces of shock absorbers by a control device, which is configured to to estimate first vertical speeds at the positions of wheels based on the vertical accelerations of a vehicle body at the positions of the wheels, to estimate second vertical speeds of the vehicle body caused by driver's driving operation based on driving operation amount of the driver, to calculate target damping forces by subtracting products of damping coefficients of the ride comfort control and second vertical speeds from the sums of products of the damping coefficients of the ride comfort control and first vertical speeds and products of damping coefficients for controlling posture change of the vehicle body and the second vertical speeds, and to control damping coefficients of the shock absorbers based on the target damping forces.

A method of operating a tilting running gear for a non-rail-borne vehicle having at least one actuator is disclosed. The method includes calculating an angle of tilt of the vehicle around an axis of rotation based on prevailing values of centrifugal acceleration and gravitational acceleration as the vehicle enters a curve. Based on a comparison between an actual lateral acceleration of the vehicle and a desired lateral acceleration of the vehicle, the vehicle is accelerated or decelerated to achieve the calculated angle of tilt. When the calculated angle of tilt has been achieved, the actuator is deactivated. The actuator provides acceleration of the vehicle and a braking device provides deceleration of the vehicle.

A sport-wheeled chassis is provided for connecting to a mobility device, which comprises a suspension set up under the bottom of the mobility device, a steering pivotally connected to the suspension, a controller connected to the suspension and steering electrically, tires which are pivotally connected to the steering and disposed under the steering, and a steering shaft of the steering which coincides axially with the steering shaft of the tire so that the controller can operate the turning direction of the tire and the height of the suspension through the suspension and the steering. The chassis is not only with a simple structure, but also with a suspension to control the height of the chassis off the ground, so that the chassis can maintain stability in any rugged environment, and, with its attached wheels, the chassis can move to desired places fast and accurately.

A steering system for a wheel of a vehicle comprises a pivot member having multiple pivot-node locations, and connectable at a first pivot-node location to a sub-frame of the wheel, a steering rod actuatable to rotate the wheel about a steering axis and mechanically coupled with the pivot member to be co-pivotable with the pivot member, and a suspension-connector rod having a first end that is connected to the pivot member at a second pivot-node location, and having at a second end that is connectable to a suspension arm linking the wheel of the vehicle to the sub-frame. When the steering system is installed in the vehicle, a lateral force acting upon the wheel is transmitted via the steering rod to the pivot member so as to rotate the pivot member, and the rotation is effective to transmit a substantially-vertical force vector to the sub-frame.

An apparatus for actively controlling stability of a vehicle is provided. The apparatus includes a strut tower brace bar that is disposed in a lateral direction of a vehicle body and opposite ends of the strut tower brace bar are individually connected to upper portions of left and right shock absorbers. Additionally, an actuator is disposed at a predetermined position in a longitudinal direction of the strut tower brace bar. When torsional deformation of the strut tower brace bar occurs due to rolling of the vehicle body, the actuator is configured to restore the strut tower brace bar by receiving gas from the left and right shock absorbers.
