Publication number: 20220348226Abstract: An apparatus for controlling a direction and speed of travel an autonomous vehicle or driver assisted autonomous vehicle (AV). A GPS and map module receive a start location and a destination location for the AV. A plurality of sensors identify a current and a proposed lane for the AV. A database of AV baseline maneuver profiles used to control one or more of direction and speed of travel of the AV is provided. A trajectory profile generator module generates a planned path for the AV with lateral acceleration less than 2 Hz, based on the start location, the destination location, the current and proposed lane for the AV, and a selected AV baseline maneuver profile from the database. A steering control module controls the direction of travel of the AV based on the generated AV planned path, and a supervisory control module controls the speed of the AV based on the generated AV planned path and inner ear constraints.Type: ApplicationFiled: June 10, 2020Publication date: November 3, 2022Inventors: David Arthur Bailey, Daniel Kee Young Kim

Patent number: 9273961Abstract: In embodiments of the invention, a vehicle stabilization control unit may determine a control moment value for one or more gyroscopes coupled to a vehicle frame to exert for stabilization of the vehicle frame. A number of input axes for the flywheels of the one or more gyroscopes to precess may be increased in order to generate the determined control moment value. In some embodiments, the one or more gyroscopes are further coupled to a turntable, and increasing the number of input axes for the flywheels comprises rotating the turntable. Furthermore, in some embodiments, the one or more gyroscopes comprise at least two gyroscopes coupled inline to the vehicle frame (e.g., aligned lengthwise with respect to the front and rear wheel to spin and precess in opposite directions with respect to each other).Type: GrantFiled: February 26, 2013Date of Patent: March 1, 2016Assignee: Lit Motors CorporationInventor: Daniel Kee Young Kim
