Abstract: Provided are methods for autonomous vehicle and audio user guidance, which can include detecting user input at a first surface, determining context data associated with a feature of the first surface and providing an instruction associated with the context data. Systems and computer program products are also provided.

Abstract: Methods, apparatus, and systems for passenger authentication and entry for autonomous vehicles are disclosed. A vehicle receives information over a first communication channel from a first mobile device. The information specifies a geographical location. The information causes the vehicle to arrive at the geographical location. The vehicle transmits a first message to a second mobile device indicating that the vehicle has arrived at the geographical location. The first message includes a graphical icon representing the vehicle. The graphical icon is for display on a user interface of the second mobile device. The vehicle receives a second message from the second mobile device over a second communication channel. The second message indicates that the graphical icon was dragged across the user interface into a graphical receptacle displayed on the user interface. Responsive to receiving the second message, at least one door of the vehicle is unlocked.

Abstract: Provided are methods and systems for establishing a line-of-sight (LoS) communications link between a first vehicle and one or more second vehicles. The LoS communications link can include a Li-Fi communications link, visible light communications (VLC) link, or other light-based communications link. LoS communications can be used to create and control caravans of vehicles.

Abstract: Among other things, vehicle cabin pressure systems and vehicle cabin pressure techniques are described for a vehicle. The vehicle includes a cabin configured to seat a plurality of passengers; at least one inlet including at least one inlet fan; at least one occupancy sensor; and at least one processor configured to execute computer executable instructions, the execution carrying out operations including: receiving a signal from the at least one occupancy sensor indicating a number of passengers within the cabin; and controlling the at least one inlet to cause air that is or has been filtered to flow into the cabin and increase a pressure in the cabin to a predetermined level above an ambient pressure level outside the vehicle based on the number of passengers in the cabin.
