Abstract: A method and system for measuring rotor position or velocity in an electric motor disposed in hydraulic fluid. The system comprises a contactless position sensor that measures electric motor rotor via magnetic, optical, or other means through a diaphragm that is permeable to the sensing means but impervious to the hydraulic fluid. An electronic sensor is positioned outside the operating fluid, whereas the motor is located in the fluid volume.

Abstract: An active suspension system is configured in a strut arrangement. The active suspension system comprises a hydraulic actuator and a hydraulic pump/electric motor assembly, wherein the actuator movement is preferably in lockstep with the hydraulic motor-pump and electric motor-generator combination. Torque in the electric motor is instantaneously controlled by a controller to create an immediate force change on the hydraulic actuator. The hydraulic actuator is configured so that it can be used as a strut whereby the actuator has sufficient structural rigidity to carry the applied suspension loads while capable of supplying damper forces in at least three quadrants of the force velocity graph of the suspension actuator operation. Embodiments disclosed include low cost active suspension systems for a MacPherson strut application.

Abstract: Hydraulic bump stops and bi-directional diverter valves may be used to protect hydraulic systems, including, for example in one embodiment, the hydraulic actuators of an active suspension system, from damage due to operation outside the normal operating range of the system. In some embodiments, a hydraulic bump stop may be used to slow down the motion of a piston at the extremes of the compression and/or extension strokes of an actuator. In another embodiment, a diverter valve may be used to protect a hydraulic motor/pump in a hydraulic system from an over-speed condition. When the piston in an active suspension system actuator moves at a speed in excess of a threshold value, one or more diverter valves may be used to divert flow away from the hydraulic motor/pump. In some embodiments, a diverter valve may be a dual or single spool bi-directional diverter valve.

Abstract: In some embodiments, a rapid-response active suspension system controls suspension force and position for improving vehicle safety and drivability. The system may interface with various sensors that detect safety critical vehicle states and adjust the suspension of each wheel to improve safety. Pre-crash and collision sensors may notify the active suspension controller of a collision and the stance may be adjusted to improve occupant safety during an impact while maintaining active control of the wheels. Wheel forces may also be controlled to improve the effectiveness of vehicle safety systems such as ABS and ESP in order to improve traction. Also, bi-directional information may be communicated between the active suspension system and other vehicle safety systems such that each system may respond to information provided to the other.

Abstract: An active suspension system for a truck cabin that actively responds to and mitigates external force inputs between the truck chassis and the cabin. The system greatly reduces pitch, roll, and heave motions that lead to operator discomfort. The assembly is comprised of two or more self-contained actuators that respond to commands from an electronic controller. The controller commands the actuators based on feedback from one or more sensors on the cabin and/or chassis.
