发明名称 System and Method of Locating Vehicles with Keylock Signals
摘要 A wireless key is signal, having a key-specific identifier, is received, the key-specific identifier detected, and the signal transmission location is calculated. The signal transmission location is stored based on the detected key-specific identifier. Another instance of the same wireless key signal is received, its key-specific identifier is detected, and the stored signal transmission location is retrieved based on the detected key-specific identifier. Optionally, a wireless key signal is received at a user and repeated at a plurality of locations in a parking facility. A vehicle response is detected, and associated with one of the repeatings of the wireless key signal. A location of the vehicle response is detected based on the repeating with which it is associated.
