Patent number: 8682539Abstract: 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.Type: GrantFiled: December 14, 2009Date of Patent: March 25, 2014Assignee: Caterpillar Inc.Inventors: Steven D. Jones, Ronald B. Warnat, Brett D. Ellen, Nathan S. Pauli, Michael S. Contratto

Publication number: 20140081522Abstract: A trailer vehicle function control system for a trailer. The system comprises an electronic control unit adapted to central the height of the trailer and communication means adapted to receive data concerning trailer height. In use, the communication means transmits data to the eieetronic control unit and the electronic control unit compares the actual tralier height with the received data concerning trailer height. If the actual trailer height is different to the remived data trailer height the electronic control unit adjusts the trailer height to the received data trailer height.Type: ApplicationFiled: September 17, 2013Publication date: March 20, 2014Applicant: Knorr-Bremse Systems For Commercial Vehicles LimitedInventor: Matthew FRY

Patent number: 8676412Abstract: A boat with several stability and handling design improvements. It has an enhanced reactive suspension system positioned in the vessel between a set of separating hull and body components. The boat also has improved braking, steering and stabilizing systems designed around multiple pivoting mechanisms on the vessel hull that work individually or in unison to achieve the desired braking or steering effect. The stabilizing system is operated by a computerized, gyroscopic hydraulic control to maintain stability and comfort of ride, minimizing the roll, pitch and yaw commonly experienced in the passenger compartment.Type: GrantFiled: December 3, 2009Date of Patent: March 18, 2014Inventor: Fred Pereira

Patent number: 8670900Abstract: In a rear wheel steering control system for a vehicle, a rear wheel steering control unit (53) forces the toe angle of each rear wheel (3rl, 3rr) to a substantially neutral position or a slightly toe-in position when a road condition estimating unit (63) has detected a rough road surface. Thereby, when the vehicle is traveling over a rough road surface, the actuator is forced to the neutral position, and the rear wheels are brought to a neutral position so that the changes in the wheel geometry (tread and/or alignment) of the rear wheels at the time of a bump or a rebound can be avoided. Therefore, the ride quality of a vehicle equipped with the rear wheel steering control system is favorably maintained even when the vehicle is traveling over a road surface, and the rear wheels undergo large vertical displacements.Type: GrantFiled: February 12, 2010Date of Patent: March 11, 2014Assignee: Honda Motor Co., Ltd.Inventor: Takashi Nishioka

Patent number: 8666596Abstract: A method and a system generates signals for influencing the movement of the body of a vehicle, wherein the chain of movements of which can be controlled or adjusted. The movement of the vehicle body is determined by sensors in relation to at least three wheels of the motor vehicle and the vertical acceleration of the vehicle body, the sensor signals that correspond to the determined sensor values are fed to a shock absorber controller which delivers at least one control signal to control actuators, in particular semi-active or active shock absorbers which are used to influence the movement of the body. The control signal for controlling the actuators is determined by the shock absorber controller from the sensor signals, with the aid of condition-dependent adjustment algorithms, taking into consideration current and/or expected conditions in conjunction with selectable requirements for the movement of the vehicle body and driving safety requirements.Type: GrantFiled: October 23, 2008Date of Patent: March 4, 2014Assignee: Volkswagen AGInventor: Andrea Arenz
