Patent number: 12086753Abstract: An AV receives a delivery request made by a user. The AV navigates to the user's location. The AV's onboard controller determines that the AV has arrived at the location. The onboard controller then commands the AV's motor to pause motion. The onboard controller provides the user an access to a delivery assembly in the AV. The onboard controller or the delivery assembly detects, by using sensors in the delivery assembly, whether an item has been removed from or placed into the container. Subsequent to detecting that the item has been removed from or placed into the container, the onboard controller commands the AV's motor to resume motion. The onboard controller or delivery assembly may also control a movable element in the container to allow the user to load or unload the item from a safe spot or control a divider in the container to protect the user's privacy.Type: GrantFiled: November 4, 2021Date of Patent: September 10, 2024Assignee: GM Cruise Holdings LLCInventors: Timothy Jon Meador, Alexis DeStasio, Andrew W.
