CPC Class H04W

When a vehicle is assigned to meet with a customer at a meeting location, as when the customer orders a ride and the taxi, ride-sharing operator, or autonomous vehicle is dispatched, the difficulty of identifying the assigned vehicle among many vehicles or the customer among many people, is solved by providing a code, unique to the meeting at the meeting location. A light signal based on the code is emitted by a first device (of the vehicle or the customer) and distinguished, based on the code, by a second device, whereby the location of the first device is determined and can be displayed or otherwise used for navigating to the other.

A method and system for selecting a subset of cloud stored data related to locations within a road network and sending it to a vehicle. A current position of the vehicle is determined. A most probable path of the vehicle is determined as a set of possible paths ahead of the vehicle that the vehicle is most probable to travel along, and a subset of data is selected related to a location that is along this most probable path. Alternatively, a respective inverse most probable path up to each respective location related to a respective subset of data is determined as a respective set of possible paths leading up to each respective location. If the current position of the vehicle is included in an inverse most probable path, the related subset of data selected. The selected subset of data is sent to the vehicle.
