Abstract
Path-based approach to passive vehicle entry is provided. A vehicle receives messages over a first protocol from a mobile device, each of the messages indicating a heading of the mobile device and a current location of the mobile device. The vehicle and the mobile device pair responsive to the current location of the mobile device being within a first threshold distance to the vehicle. Responsive to the heading indicating that the mobile device is headed towards the vehicle and the current location of the mobile device being within a second threshold distance from the vehicle, the second threshold distance being closer to the vehicle than the first threshold distance, the vehicle activates one or more second transceivers to perform time of flight distance measurement between the vehicle and the mobile device to obtain more precise positional accuracy, and otherwise maintains the one or more second transceivers in a deactivated mode.
