Publication number: 20230017774Abstract: Methods are provided for proactively controlling a component of a system. The system may comprise a vehicle and the component may comprise a suspension of the vehicle. According to various aspects, methods may include obtaining information regarding a travel surface along a travel path that the system will travel at a future time and, based on the information regarding the travel surface, controlling the component of the system to traverse the travel surface. Controlling the component based on the information regarding the travel surface may comprise comparing the information regarding the travel surface to information regarding at least one physical constraint of the system and/or comparing frequency content of the information regarding the travel surface to a threshold frequency. Proactive control methods may provide improved response to disturbances and improved tracking and isolation because a suspension may be controlled with reduced or substantially zero delay.Type: ApplicationFiled: December 30, 2020Publication date: January 19, 2023Applicant: ClearMotion, Inc.Inventors: Marco Giovanardi, William Graves, Allen Chung-Hao Chen
