  • Patent number: 11613381
    Abstract: A launchpad is sized and shaped to accommodate an autonomous vehicle (AV) that includes at least one vehicle sensor. The launchpad includes one or more launchpad sensors located on or around the launchpad. A control subsystem receives launchpad sensor data from the launchpad sensor(s) and AV sensor data from the vehicle sensor(s). In response to the request for departure of the AV, the control subsystem determines, based at least in part upon the launchpad sensor data, whether the launchpad is free of obstructions that would prevent departure from the launchpad and determines, based at least in part upon the AV sensor data, whether the region in front of the AV is clear of obstructions that would prevent movement away from the launchpad. If both the launchpad and the region in front of the AV are free of obstructions, the AV is permitted to begin driving autonomously.
