Patent number: 11970227Abstract: Methods, systems and a vehicle control system for a vehicle is provided. The vehicle control system includes an Electric Power Steering System (EPS), and a sensor system including a vehicle dynamics sensor configured to provide vehicle dynamics data and a temperature sensor configured to provide measured outside temperature. A processor is in operable communication with the EPS and the sensor system. The processor is configured to execute program instructions. The program instructions are configured to cause the processor to: execute an automated lateral control algorithm based on the vehicle dynamics data to generate a steering command, adapt the automated lateral control algorithm based on the measured outside temperature so that the steering command compensates for changing lateral response of the vehicle as a result of changing environmental temperature; and provide the steering command to the EPS, wherein the EPS is configured to laterally control the vehicle based on the steering command.Type: GrantFiled: June 17, 2022Date of Patent: April 30, 2024Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Reza Zarringhalam, Jimmy Lu, Brian Porto, Ethan Thomas Dietrich
