  • Patent number: 10343480
    Abstract: A valve control device is configured to execute a specific valve control when a valve switching condition at high pressure is satisfied. The specific valve control switches the spring constant change valves for front wheel to a blocking state and switches a spring constant change valves for rear wheel to a communication permission state. The valve switching condition at high pressure is satisfied when oil pressure of hydraulic oil of rear wheel side oil hydraulic cylinders, which is detected by rear wheel side oil pressure detection means, is more than or equal to a predetermined oil pressure threshold and the traveling state determination means determines that a vehicle is in a predetermined traveling state.

    Abstract: A machine employing controllable mounts and a method for controlling such mounts based on machine operation are disclosed. The controllable mount may include a housing, a pin, rheological fluid within the housing and coils provided proximate to the rheological fluid. As current is applied to the coils, the apparent viscosity of the rheological fluid is increased, and in so doing so are the damping and stiffness properties of the controllable mount. With other operations such as roading or working on a flat surface, the feedback afforded by the mounts is not as important as operator comfort, in which case the current applied to the coils can be lowered and thus the mount can be made more relaxed. The machine of the present disclosure identifies the machine operation being performed through sensors, predictive algorithms, implement position, and operator input and sets the current and properties of the controllable mounts accordingly.

  • Patent number: 8272650
    Abstract: A low-end adjusting mechanism for vehicle suspensions useful for compensating rolling and pitching motions and for leveling purposes, in which a vehicle spring (1) having a longitudinal axis is mounted between two spring seats or receptacles (2, 3), and at least one spring seat can be adjusted in the direction of the longitudinal axis of the spring by rod shaped coupling elements which are mounted at both ends in an articulated or pivotable manner.

  • Patent number: 8219282
    Abstract: A control system (18) and method for an automotive vehicle (10) includes a pitch rate sensor (37) generating a pitch rate signal, a longitudinal acceleration sensor (36) generating a longitudinal acceleration signal, and a yaw rate sensor (28) generating a yaw rate signal. A safety system (44) and the sensors are coupled to a controller. From the sensors, the controller (26) determines an added mass and a position of the added mass, a pitch gradient and/or a pitch acceleration coefficient that takes into account the added mass and position. The controller controls a vehicle system in response to the added mass and the position of the added mass, the pitch gradient and/or pitch acceleration coefficient variables.

  • Patent number: 8191903
    Abstract: A gas spring system of a vehicle includes a multi-chamber gas spring associated with each vehicle wheel. Each multi-chamber gas spring comprises a main chamber and at least one auxiliary chamber connectable to the main chamber, such that the spring rigidity of the multi-chamber gas springs can be changed. A control device determines a target axle rigidity as a function of a guide lateral acceleration and adjusts the target rigidity. The spring rigidity of the multi-chamber gas spring located on an inner side of the vehicle (relative to a curve traversed by the vehicle) is first changed. The spring rigidities of the multi-chamber gas springs of a vehicle axle are changed in stages in an alternating fashion.

  • Patent number: 8190327
    Abstract: The invention relates to a device for controlling the suspension of the body shell of a motor vehicle. The inventive device comprises a calculator (CSS) which can calculate a control value (ER) for an actuator (M) of a shock absorber (AM) of the suspension (S) as a function of at least one modal body shell speed calculated from a modal body shell acceleration. The invention is characterized by a sensor (CAP-DEB) for sensing wheel (A,B, C, D) travel in relation to the body shell, which is connected to a first means (CAL) for calculating the modal body shell acceleration from the travel measurement (DEB) provided by the sensor (CAP-DEB).

  • Patent number: 8170749
    Abstract: A target roll angle of the vehicle is computed based on an actual lateral acceleration at the centroid of the vehicle, and the lateral acceleration of the vehicle at the centroid is corrected by use of lateral acceleration correction amounts based on a yaw rate of the vehicle, whereby the lateral accelerations of the vehicle at the front wheel position and the rear wheel position are computed. Subsequently, target anti-roll moments at the front wheel position and the rear wheel position are computed based on the target roll angle and the accelerations of the vehicle at the front wheel position and the rear wheel position, and active stabilizer apparatuses of the front and rear wheels are controlled based on these target anti-roll moments.

  • Patent number: 8128110
    Abstract: A combination of existing suspension designs is provided to suspend moving vehicles such as cars, trucks, planes, and snowmobiles and provide two degrees of freedom in the wheels or skis. The design combines a dive suspension with a roll suspension, including a locking linkage. The locking linkage locks out the roll suspension during dive, jounce, flight or two-wheel bump motion. Both the dive and roll suspensions are responsive during roll motion and one-wheel bump motion.
