Abstract: It is an object of the invention to provide a suspension system configured to execute a control for avoiding a state in which an operation of an electric motor which is a power source of an electromagnetic actuator is kept halted at a certain operational position while the motor is generating a motor force. Where a target rotational position of the motor becomes equal to a specific operational position (e.g., a rotational position at which an electrifying current amount of one phase reaches a peak value), a control for shifting the target rotational position by δθ is executed. Where the rotational position of the motor is kept located at the certain position for a time period longer than a prescribed time, a control for changing the rotational position of the motor is executed. According to the present suspension system, it is possible to suppress imbalance in heat generation in the motor and to thereby reduce a load to be applied to the motor. Accordingly, a suspension system with high utility is realized.

Abstract: A method of positioning a vehicle chassis of a stationary vehicle in approximate alignment with a predetermined datum is provided. The vehicle has an axle and a fluid suspension system. The fluid suspension system include a control device, a pressurized fluid source and an exhaust passage. The pressurized fluid source and the exhaust passage are in fluid communication with the plurality of fluid suspension members through the control device. The vehicle also includes an electronic control unit operatively associated with the control device. The method including step of providing alignment sensor supported on the chassis for outputting a signal indicative of the orientation of the chassis to the electronic control unit and acquiring a signal output by the alignment sensor. Another step includes comparing the signal from the alignment sensor to alignment data stored in the electronic control unit. A further step includes selectively operating the control device to permit fluid communication between one or more of the fluid suspension members and one of the pressurized fluid source and the fluid exhaust until the signal from the alignment sensor approximately corresponds to the alignment data. A system for performing the method is discussed.

Abstract: A vehicle leveling system including at least one level sensor, a controller and an output. The sensor measures how level the vehicle is relative to horizontal. Optionally, it does so dynamically, as the vehicle moves across a potential parking area. The controller analyzes the sensor measurements, and informs the operator via the output whether the vehicle is level in a given direction, whether the vehicle is leveling, whether the vehicle can be leveled at a given location, and/or the “best” leveling that the system is capable of at a location. The system also may automatically level the vehicle relative to the ground for the operator. In one embodiment, the leveling system communicates with an existing vehicle electronic height control system. The leveling system overrides or controls the normal operation of this system, and uses it to level the vehicle, for example, by adjusting the vehicle suspension.

Abstract: The present invention provides a transmissibility shaping control for active suspension systems. The T-shaping control is a combination of several sub-strategies using the dynamic information in the frequency domain. Each strategy works dominantly in a certain frequency range to achieve a desirable transmissibility for better suspension performance in the corresponding frequency range. Different sub-strategies for different frequency ranges include stiffness control, skyhook control, groundhook control, and various damping levels. In addition, an embodiment is provided utilizing tunable compressible fluid struts in an active vehicle suspension.

Abstract: A damper for use with an automotive coil over shock absorber. An outer damping sleeve is retained over the exterior surface of an inner body and includes a plurality of bypass ports to alternately align and unalign with bypass ports of the inner body to regulate a bypass flow of damping oil between an interior volume and an outer passage, thereby allowing variable damping control of the damper. The outer damping sleeve is connected to an internal floating piston (IFP) which rides inside the inner body. A control spring is retained for applying a force to the IFP to limit the free movement of the IFP and thereby control a damping force of the damper during the damping event. Increased pressure in the hydraulic damping oil causes the IFP to move, causing the bypass ports to open and close depending on the forces subject to the damper.

Abstract: Vehicle cab suspension control systems are disclosed herein. In some embodiments, the cab suspension control systems can include front cab-to-frame mounts that include controllable elastomer-based isolators that can provide real time variable damping to improve ride quality and/or road holding and reduce cab roll in response to, for example, input from one or more cab and/or frame mounted accelerometers, position sensors, etc. Embodiments of the control systems described herein can utilize a single vehicle controller (e.g., an ECU) to control all of the cab suspension components (e.g., semi-active damping technologies, air spring technologies, etc.) employed on a vehicle to provide a single suspension control solution that can provide improved ride performance, road holding, etc.
