Patent number: 11669098Abstract: Autonomous control of a subject vehicle including a longitudinal motion control system includes determining states of parameters associated with a trajectory for the subject vehicle and parameters associated with a control reference determined for the subject vehicle. A range control routine is executed to determine a first parameter associated with a range control command based upon the states of the plurality of parameters, and a speed control routine is executed to determine a second parameter associated with a speed control command based upon the states of the plurality of parameters. An arbitration routine is executed to evaluate the range control command and the speed control command, and operation of the subject vehicle is controlled to achieve a desired longitudinal state, wherein the desired longitudinal state is associated with a minimum of the range control command and the speed control command.Type: GrantFiled: February 7, 2019Date of Patent: June 6, 2023Assignee: GM Global Technology Operations LLCInventors: Nikolai K.

Patent number: 11332152Abstract: A vehicle including a Global Positioning System (GPS) sensor, an Inertial Measurement Unit (IMU), and an Advanced Driver Assistance System (ADAS) is described. Operating the vehicle includes determining, via the GPS sensor, first parameters associated with a velocity, a position, and a course, and determining, via the IMU, second parameters associated with acceleration and angular velocity. Roll and pitch parameters are determined based upon the first and second parameters. A first vehicle velocity vector is determined based upon the roll and pitch parameters, the first parameters, and the second parameters; and a second vehicle velocity vector is determined based upon the roll and pitch parameters, road surface friction coefficient, angular velocity, road wheel angles and the first vehicle velocity vector. A final vehicle velocity vector is determined based upon fusion of the first and second vehicle velocity vectors. The vehicle is controlled based upon the final vehicle velocity vector.Type: GrantFiled: May 29, 2020Date of Patent: May 17, 2022Assignee: GM Global Technology Operations LLCInventors: Nikolai K.

Patent number: 10974758Abstract: A method and apparatus that control lateral movement of the vehicle during backward motion are provided. The method includes loading a desired backward path of vehicle, the backward path comprising waypoints to be traveled along during a rearward motion of the vehicle, reflecting the waypoints along a reflection axis perpendicular to a longitudinal axis that runs from front to back of the vehicle such that the reflected waypoints define virtual forward path; and controlling lateral movement of the vehicle to follow the waypoints along the forward path while the vehicle is traveling in a backward direction.Type: GrantFiled: November 19, 2018Date of Patent: April 13, 2021Assignee: GM Global Technology Operations LLCInventors: Nikolai K.

Publication number: 20200101979Abstract: An automotive vehicle includes an actuator configured to control vehicle steering, acceleration, or shifting, a sensor configured to provide signals indicative of a lateral distance between a current vehicle location relative to a desired path, and a controller. The controller is configured to, in response to a determination that the lateral distance exceeds a threshold, automatically control the actuator according to an interstitial path. The interstitial path is automatically defined by the controller, and is based on a b-spline defined by a first position boundary condition at the current vehicle location, a second position boundary condition at a merge location relative to the desired vehicle path, a first curvature boundary condition based on a current vehicle yaw rate, and a second curvature boundary condition based on a curvature of the desired vehicle path at the merge location. The interstitial path is further optimized based on a cost function.Type: ApplicationFiled: September 28, 2018Publication date: April 2, 2020Inventors: Nikolai K.
