A sway-bar actuator for a vehicle includes a motor that rotationally operates a lead rod to axially operates a push rod. Operation of the push rod axially operates an attachment fork between an engaged position and a disengaged position. The engaged position is characterized by a unified operation of opposing stabilizing bars. The disengaged position is characterized by independent rotational operation of the opposing stabilizing bars. A sensor rod is coupled to and operates axially with the attachment fork. A sensor assembly has a rotator and a sensor magnet. Axial operation of the sensor rod produces a rotational operation of the sensor magnet. The sway-bar actuator includes an encoder, where a rotational position of the sensor magnet relative to the encoder corresponds to an axial position of the attachment fork and the push rod relative to the engaged and disengaged positions.

Disclosed is an automatic vehicle suspension tuning system. The system has a control module to receive user input, an ECU with a processor and a memory, one or more road condition sensors, and one or more controllable suspension system components. The ECU controls the adjustments of the controllable suspension system component in response to user input to the control module as well as input from the road condition sensors during operation of the vehicle. A method of tuning a controllable suspension system component is also disclosed.

A method and device for the combined determining of a momentary vehicle roll angle of a motor vehicle and a momentary roadway cross slope of a curved roadway section traveled by the motor vehicle is disclosed. The momentary vehicle roll angle and momentary roadway cross slope are determined from chassis data and transverse dynamics data of the motor vehicle.

A method for reducing the rollover risk of an automotive vehicle includes: a first step of calculating, on the basis of a plurality of signals delivered by sensors (28, 29) of the controllable suspension system, a measured quantity (TCm) as an active value (TC) of a load transfer; a second step of calculating an estimated quantity (TCe), on the basis of signals delivered by kinematic sensors (50-58) placed onboard the vehicle and a dynamic model of the vehicle, the estimated quantity being taken as an active value of the load transfer when the measured quantity is not available; a step of evaluating the rollover risk on the basis of the active value (TC) of the load transfer; and, in the event of increased rollover risk; and a step of the emission of a safety signal (S).

An apparatus for controlling a stabilizer bar including: a steering angular velocity detection unit configured to detect a steering angular velocity of a vehicle in operation; a steering angle detection unit configured to detect a steering angle of the vehicle; and a control unit configured to determine whether the vehicle is turning, based on the steering angular velocity information and the steering angle information of the vehicle, and perform clutch coupling by driving a clutch of a stabilizer bar having the clutch applied thereto, when it is determined that the vehicle is turning. The control unit decides a clutch coupling time period in response to an instantaneous turning velocity of the vehicle, and performs the clutch coupling in response to the decided clutch coupling time period.

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.

A resisting force change mechanism includes a first portion and a second portion configured to change a resisting force against relative displacement. The first portion is supported on any one of a first side member, a second side member, a first cross member, and a second cross member of a link mechanism where at least a portion thereof is superposed on one member at all times. The first portion is aligned with the one member and a steering shaft at the front. The second portion is supported on any other one of the body frame, the first side member, the second side member, the first cross member, and the second cross member that is displaced relative to the one member on which the first portion is supported. The second portion is located at a position where at least a portion thereof is superposed on the other member at all times.

A method for operating a motor vehicle which includes an active chassis system with which it is possible to change a wheel load distribution between two rear wheels and two front wheels which are deflected relative to a supporting structure of the motor vehicle by a steering system during a maneuvering process, wherein friction occurs at the front wheels owing to ground contact. In order to prevent the occurrence of undesired noise during the maneuvering, during the maneuvering process with the large wheel deflection, the wheel load at a first wheel pair, which comprises a left/right front wheel and a right/left rear wheel arranged diagonally with respect thereto, is reduced selectively compared to a second wheel pair, which comprises a right/left front wheel and a left/right rear wheel arranged diagonally with respect thereto, in order to reduce the friction at one of the two front wheels during the maneuvering.
