Patent attributes
The disclosure pertains to using ultra-wideband (UWB) radio communications to execute a pedestrian-vehicle rendezvous. In one example operation, a personal device such as a smartphone, is used to identify a location of a vehicle with a first level of accuracy. For example, the smartphone may be used by a pedestrian to obtain GPS location coordinates of a ride-hail vehicle summoned by the pedestrian. The vehicle may be located relatively far from the pedestrian. The smartphone may be configured to automatically establish a UWB radio link with a UWB transponder in the vehicle and/or a smartphone carried by a driver of the ride-hail vehicle, when the vehicle is within range to establish UWB communications. The UWB radio link may be used to execute one or more of various procedures to locate the vehicle with a second level of accuracy that is higher than the first level of accuracy.
