  • Patent number: 12038783
    Abstract: A system for synchronization of multiple clocks in a vehicle network includes a processor that is programmed to synchronize a time follower clock to a primary grand leader clock. The primary grand leader clock is monitored and the time follower clock is synchronized to a standby grand leader clock upon a failure of the primary grand leader clock. The time follower clock is synchronized to the primary grand leader clock if a new ignition cycle has occurred between a failure of the primary grand leader clock and a recovery after failure of the primary grand leader clock. The time follower clock continues to be synchronized to the standby grand leader clock if a new ignition cycle has not occurred between the failure of the primary grand leader clock and the recovery after failure of the primary grand leader clock.

  • Patent number: 12039484
    Abstract: 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.
