Patent number: 12240492Abstract: Methods and systems of controlling a vehicle. The methods and systems include switching to a second processor executed mode in response to determining that a range of perception information extends to a range end point that is closer to the vehicle than a first Look Ahead (LA) point. In the second processor executed mode: a motion planner requests a lateral controller to provide a closer LA point relative to the vehicle. The lateral controller determines the closer LA point and sends the closer LA point to the motion planner. The lateral controller generates control commands for an EPS system based on an error between a desired trajectory and an actual trajectory at the closer LA point. The motion planner generates the desired trajectory based on perception data and the closer LA point.Type: GrantFiled: December 8, 2022Date of Patent: March 4, 2025Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Tetyana V Mamchuk, Paul A Adam, Reza Zarringhalam, Zhi Li
