A method of on-demand energy delivery to an active suspension system is disclosed. The suspension system includes an actuator body, a hydraulic pump, an electric motor, a plurality of sensors, an energy storage facility, and a controller. The method includes disposing an active suspension system in a vehicle between a wheel mount and a vehicle body, detecting a wheel event requiring control of the active suspension; and sourcing energy from the energy storage facility and delivering it to the electric motor in response to the wheel event.

Active vehicle suspension

A method of on-demand energy delivery to an active suspension system comprising an actuator body, hydraulic pump, electric motor, plurality of sensors, energy storage facility, and controller is provided. The method comprises disposing an active suspension system in a vehicle between a wheel mount and a vehicle body, detecting a wheel event requiring control of the active suspension; and sourcing energy from the energy storage facility and delivering it to the electric motor in response to the wheel event.

Active vehicle suspension system

Method and apparatus for improving the performance, response, and durability of an electro-hydraulic active suspension system. The noise caused by hydraulic flow ripple is reduced and system response is improved.

Apparatus and method for active vehicle suspension

Gerotor pump with bearing

Various embodiments related to hydraulic actuators and active suspension systems as well as their methods of use are described.

Hydraulic actuator with on-demand energy flow

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.

Contactless sensing of a fluid-immersed electric motor

A method of operating a remote vehicle configured to communicate with an operator control unit (OCU) includes executing a click-to-drive behavior, a cruise control behavior, and a retro-traverse behavior on a computing processor. The click-to-drive behavior includes receiving a picture or a video feed and determining a drive destination in the received picture or video feed. The cruise control behavior includes receiving an absolute heading and velocity commands from the OCU and computing a drive heading and a drive velocity. The a retro-traverse behavior includes generating a return path interconnecting at least two previously-traversed waypoints of a list of time-stamped waypoints, and executing a retro-traverse of the return path by navigating the remote vehicle successively to previous time-stamped waypoints in the waypoints list until a control signal is received from the operator control unit.
