  • Publication number: 20240137740
    Abstract: Among other things, stored data is maintained indicative of potential stopping places that are currently feasible stopping places for a vehicle within a region. The potential stopping places are identified as part of static map data for the region. Current signals are received from sensors or one or more other sources current signals representing perceptions of actual conditions at one or more of the potential stopping places. The stored data is updated based on changes in the perceptions of actual conditions. The updated stored data is exposed to a process that selects a stopping place for the vehicle from among the currently feasible stopping places.

  • Patent number: 11772669
    Abstract: Among other things, a vehicle drives autonomously on a trajectory through a road network to a goal location based on an automatic process for planning the trajectory without human intervention; and an automatic process alters the planning of the trajectory to reach a target location based on a request received from an occupant of the vehicle to engage in a speed-reducing maneuver.

  • Patent number: 11627450
    Abstract: Among other things, a vehicle is caused to drive autonomously through a road network toward a defined goal position, and, if no potential stopping place that is in the vicinity of the goal position and is acceptable and feasible can be identified, a human operator not onboard the vehicle is enabled to drive the vehicle to a stopping place.

  • Publication number: 20210019854
    Abstract: Among other things, a signal is emitted from a signaling device and is captured by stimulus detectors location on a vehicle, including an autonomous vehicle. Properties of the signal are analyzed, potentially in concert with other information, to determine the precise location of the signaling device and therefore the precise goal location for picking up a rider of the autonomous vehicle. In response to the calculation of the precise goal location, the autonomous vehicle attempts to travel to a location as near as possible to the precise goal location to facilitate entry of the rider into the vehicle.

  • Patent number: 10857994
    Abstract: Among other things, a planning process is associated with an autonomous vehicle. The planning process has inputs including static map data and dynamic data from sensors on the autonomous vehicle and outputs including a route to be driven through a road network to reach a goal position, a continually updated choice of a currently selected stopping place in the vicinity of the goal position, and a trajectory to be executed through a road network to reach the currently selected stopping place. A communication element communicates information about the updated choice of a currently selected stopping place to a device of a passenger, receives from the device of the passenger information about the goal position, and delivers the information to the planning process as an input.
