Patent number: 11618330Abstract: An EV can be autonomously charged by using its localization and navigation capabilities. The EV determines its pose in a local area and establishes a connection with a charger coordination system. The EV requests the charger coordination system to find a charging station in the local area based on the EV's pose. The charger coordination system uses the EV's pose to find the charging station. The charger coordination system sends the location of the charging station to the EV. The EV navigates to the charger. The EV further determines its pose relative to the charging station and aligns its charge port with the charger plug of the charging station. The EV may plug itself in or request the charger coordination system to insert the charger plug into the charge port. The alignment and insertion process may be managed by using force sensors on the charger plug or charge port.Type: GrantFiled: October 5, 2021Date of Patent: April 4, 2023Assignee: GM CRUISE HOLDINGS LLCInventors: Darren Hau, Vincent P.

Patent number: 11618467Abstract: Various technologies described herein pertain to causing presentation on a user interface of an immediate portion of a navigation route of an autonomous vehicle. A computing system of the autonomous vehicle determines whether an object detected by sensor(s) of the autonomous vehicle proximate to the immediate portion of the navigation route are of a type and relative position defined as one of consequential and inconsequential for a human passenger. In response to determining that an object has both a type and relative position defined as consequential, the computing system causes presentation on the user interface a representation of the object relative to the immediate portion of the navigation route to provide a confidence engendering indication that the autonomous vehicle has detected the object. Otherwise if inconsequential, presentation on the user interface of any representation of the object is not caused by the computing system to avoid creating a confusing presentation.Type: GrantFiled: December 31, 2020Date of Patent: April 4, 2023Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Stephanie Olivia Engle, Mariya Jacobo, Jacqueline Mary Shannon, David Hyon Berrios, Tejeswara Reddy Pogula, John Logan Anderson, Divya Thakur

Patent number: 11618478Abstract: An autonomous vehicle (AV) implements a health protocol that may reduce pathogen transmission between users of the AV. The AV is equipped with a thermal sensor that captures a body temperature of a user. The AV compares the user's temperature to a threshold temperature, and if the user's temperature exceeds the threshold temperature, the AV performs checks to ensure that the user's planned trip follows current regulations or recommendations. For example, the AV confirms that the user is traveling between the user's home and a healthcare facility. If the trip is permitted, the AV enables the user to enter the AV. The AV may include a disinfectant system for disinfecting the passenger compartment or surfaces after the user exits the AV.Type: GrantFiled: February 11, 2022Date of Patent: April 4, 2023Assignee: GM CRUISE HOLDINGS LLCInventor: Jennifer Devar McKnew
