Patent number: 11802815Abstract: A vehicle is received in a stationary controlled area of a controlled testing environment. Simulation inputs corresponding to a simulated scene are generated and transmitted to the vehicle. The vehicle applies torque in response. A vehicle control mechanism of the controlled testing environment, such as a chassis dynamometer, a motorized treadmill, or a lift, keeps the vehicle within the stationary controlled area during the test despite the torque applied by the vehicle. A path of the vehicle within the simulated scene is determined based on the applied torque, based upon which the vehicle's navigation system is calibrated.Type: GrantFiled: February 9, 2023Date of Patent: October 31, 2023Assignee: GM Cruise Holdings LLCInventors: Mahesh Seetharaman, Kevin Chu, Dennis Jackson
