Patent number: 10984260Abstract: Operation of a vehicle that includes an autonomous operating system including an on-board map database includes operating in a travel lane employing a lane keeping control system and an adaptive cruise control system and monitoring a plurality of lane reference markers. Periodically, parameters are determined, including a first lateral offset for the vehicle based upon a forward-monitoring sensor and one of the lane reference markers, and a second lateral offset for the vehicle based upon a GPS sensor and the map database. A difference and an associated variance are determined, and an error in the map database is determined when the variance is greater than a threshold variance. The vehicle operator is alerted to actively control the vehicle based upon the detected error in the map database.Type: GrantFiled: May 23, 2019Date of Patent: April 20, 2021Assignee: GM Global Technology Operations LLCInventors: Xiaofeng F.

Patent number: 10124828Abstract: Methods, apparatus and systems are provided for steering a vehicle, for example, during autonomous operation. One exemplary method involves operating a locking system associated with a first set of one or more wheels of the vehicle to lock an angle of the wheel(s) and detecting a steering adjustment condition based on the angle during subsequent operation of the vehicle. In response to the steering adjustment condition, the locking system is operated in an intermediate mode, and then thereafter operated to relock the angle of the wheel(s) based on monitoring the angle of the wheel(s) during operation in the intermediate mode.Type: GrantFiled: June 15, 2016Date of Patent: November 13, 2018Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Pinaki Gupta, Nikhil L.

Patent number: 9440600Abstract: Method for operating a fail operational power system for a vehicle includes monitoring voltages on first and second power distribution paths arranged in parallel. Each path includes a respective first or second isolator switch effective when operative in a closed state to power the respective path by a respective energy storage device for supplying electrical power to one or more loads partitioned on each of the paths. A third isolator switch controllably operative between open and closed states is monitored. The closed state of the third isolator switch connects the paths and the open state opens the connection between the paths. When a predetermined operating mode requiring fail operational power is enabled, the third isolator switch is controlled to the open state when at least one of the monitored voltages violates a reference voltage and is controlled to the closed state when neither one of the monitored voltages violate the reference voltage.Type: GrantFiled: September 3, 2013Date of Patent: September 13, 2016Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: David P.
