An electro-dynamically controlled leveling system having a plurality of air springs mounted on at least one axle of a vehicle for supporting the weight of the vehicle; one or more electro-pneumatic valves; and one or more sensors that monitor one or more characteristics of the vehicle and transmit the one or more characteristics as a sensory input. The electro-dynamically controlled leveling system includes a central control module in electrical communication with the one or more sensors and the one or more electro-pneumatic valves. The central control module receives the sensory input from the one or more sensors, calculates a dynamic condition of the vehicle based on the sensory input, determines a desired air pressure for each air spring based on the calculated dynamic conditions of the vehicle, and transmit a command to the electro-pneumatic valves to adjust the air pressure of the air springs.

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.

In a suspension controlling apparatus for a vehicle which includes a suspension whose damping force is variably settable and a control unit capable of executing skyhook control on the basis of target damping force for skyhook control to control the damping force of the suspension, the vehicle stability is raised upon skyhook control during turning of the vehicle. Target damping force limit value determination device provided in a control unit determines target damping force limit values for skyhook control such that a value obtained by subtracting, from the target damping force limit value on the decompression side when the suspension is in a decompressed state, the target damping force limit value on the compression side when the suspension is in a compressed state increases as a roll angle detected by a roll angle sensor increases. The control unit limits the target damping forces with the target damping force limit value.

A system for signaling road hazards and emergency actions to nearby road users comprising a vehicle, the vehicle having at least three wheels, a vehicle control circuitry, one or more sensors, and a vehicle system controller. The vehicle control circuitry monitors data from the one or more sensors, detects hazardous situations, and controls the vehicle system controller to control the vehicle, induce a dynamic vehicle behavior, and visually signal the vehicle is performing an emergency maneuver.

Systems and methods for controlling a vehicle including a friction control device are provided. A method of controlling the vehicle includes operating at least one friction control device in a first of a plurality of friction modes, detecting a vehicular speed, changing operation of the at least one friction control device from the first friction mode to a second of the plurality of friction modes in response to the vehicular speed exceeding a first threshold speed value, and changing operation of the at least one friction control device from the second friction mode to the first friction mode in response to the vehicular speed falling below a second threshold speed value that is less than the first threshold speed value. The second friction mode is associated with a higher level of resistance than the first friction mode.

A vehicle includes an electric actuator disposed outside a vehicle body, a battery 16 and a boosting circuit which supply a high voltage to the electric actuator, and an electric suspension control ECU which controls the boosting circuit and the electric actuator, and in a case where a running speed is equal to or less than a first speed, the electric suspension control ECU limits the supply of the high voltage to the electric actuator.

A road surface condition is determined appropriately. A road surface determining section (84) configured to determine a road surface condition with reference to a wheel speed signal indicative of wheel speeds includes a band-stop filter (841) which acts on the wheel speed signal and has a cutoff frequency band which is changed in accordance with the wheel speed signal.

The present invention makes it possible to appropriately grasp a stop cause when a vehicle stops. An ECU 5, which controls a vehicle including wheels and a vehicle body connected to the wheels includes: a wheel stop detection unit 138 that detects a stop of the wheels; a vehicle body stop detection unit 133 that detects a stop of the vehicle body; and a stop cause determination unit 141 that determines a stop cause of the vehicle based on a stop timing of the wheels detected by the wheel stop detection unit 138 and a stop timing of the vehicle body detected by the vehicle body stop detection unit 133. The stop cause determination unit 141 may determine that the stop cause is contact of the vehicle body with an obstacle when the stop timing of the vehicle body is earlier than the stop timing of the wheels.

A system for controlling an active suspension of a vehicle may include a sensor device mounted on the vehicle to detect a state of the vehicle, and a vehicle controller that estimates a pitch angle of the vehicle using the state information related to the vehicle when pulling of the vehicle occurs in a pitch control situation based on a willingness of a driver to accelerate or decelerate the vehicle, determines a sum of a control force of a front wheel of the vehicle and a control force of a rear wheel of the vehicle for minimizing the pitch angle, and compares a steering intention of the driver with a yaw rate signal of the vehicle to determine control amounts of a left active suspension of the vehicle and a right active suspension of the vehicle based on a magnitude of pulling of the vehicle.

The four wheel steering vehicle utilizes a cage system that extends along the longitudinal axis to protect the driver coupled to a center rail chassis. Front and Back independent suspension links extend outward along the lateral axis pivotally connected to the wheel assemblies enabling four wheel independent suspension. A centrally located pivoting shock provides both steering control and suspension attachment for the shock and spring. The vehicle is controlled by the driver using a steering wheel, acceleration pedal, and a brake pedal. The invention provides a feeling of integration with the vehicle as the driver rolls into turns with the vehicle, while minimizing fatigue caused by the continuous resistance to centrifugal cornering forces.
