Abstract
Medium-range remote communication and control for a vehicle is achieved with a wireless vehicle telematics unit, a medium-range wireless portable fob, and an unmodified wireless personal communication device. The portable fob includes a medium-range RF transceiver for bi-directional communication with the telematics unit and a short-range wireless transceiver for bi-directional communication with the personal communication device. The fob communicates with the vehicle telematics unit in a conventional manner, and also relays information between the telematics unit and the personal communication device. Communication can be initiated by the telematics unit or by the operator via the fob or personal communication device. Once communication is initiated, the fob relays: (1) menu options and status information from the telematics unit to the personal communication device; and (2) menu selections from the personal communication device to the telematics unit. No cellular network service or special programming is required for the personal communications device.
