Publication number: 20240100899Abstract: 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.Type: ApplicationFiled: June 28, 2023Publication date: March 28, 2024Applicant: ClearMotion, Inc.Inventors: Zackary Martin Anderson, Marco Giovanardi, Clive Tucker, Jonathan R.

Patent number: 11879451Abstract: Presented herein are systems and methods for attenuating flow ripple generated by a hydraulic pump. In certain aspects, a method and system for operating a hydraulic positive displacement pump according to a stabilized command profile are disclosed, such that flow ripple generated by operation of the pump according to the stabilized command profile is attenuated as compared to operation of the pump according to a corresponding nominal command profile. In other aspects, a pressure-balanced active buffer is disclosed that allow for at least partially cancelling flow ripple in a hydraulic circuit comprising a pump. In another aspect, a method for generating ripple maps for a pump is disclosed. Such ripple maps may be used, for example, to determine the stabilized command profile used to operate the pump, or may be used by the pressure-balanced active buffer to counteract ripple in the hydraulic circuit.Type: GrantFiled: March 11, 2021Date of Patent: January 23, 2024Assignee: ClearMotion, Inc.Inventors: Colin Patrick O'Shea, Clive Tucker, Brian Alexander Selden

Patent number: 11815110Abstract: Presented herein are systems and methods for attenuating certain pulsations in a hydraulic system comprising a pump and a hydraulic actuator. In certain aspects, an accumulator comprising an internal volume that is divided into a working chamber and a contained chamber may be utilized to at least partially attenuate propagation of certain pulsations in the system. The working chamber may be fluidically coupled to the pump via a first flow path and fluidically coupled to a chamber of the actuator via a second flow path. The system may be designed such that a first inertance of the first flow path is greater than a second inertance of the second flow path. Additionally or alternatively, the system may be designed such that a resonance associated with the first inertance and a compliance of the accumulator may occur at a resonance frequency of less than 90 Hz.Type: GrantFiled: September 12, 2022Date of Patent: November 14, 2023Assignee: ClearMotion, Inc.Inventors: Nathan Woodard, Colin Patrick O'Shea, Hector Arnaldo Inirio

Publication number: 20220373003Abstract: Hydraulic systems and methods for reducing the propagation of flow and/or pressure pulsations within a hydraulic system are described. In one embodiment, a hydraulic system may include a hydraulic device and a differential buffer fluidly connected to the hydraulic device. The differential buffer may include a piston that is exposed to pressure pulsations that propagate along separate flow paths and that are at least partially out of phase with one another. Corresponding displacement of the piston due to the out of phase pulsations may at least partially mitigate propagation of the pulsations within the hydraulic system downstream from the differential buffer.Type: ApplicationFiled: November 13, 2020Publication date: November 24, 2022Applicant: ClearMotion, Inc.Inventors: Colin Patrick O'Shea, Brian Alexander Selden, Clive Tucker
