ABSTRACT:
A vehicular telecommunications system having user detection features. A telephone controller 504 is comprised in a vehicle and adapted to process a plurality of telephone signals. A telephone 37 is configured to receive telephone calls for the user from sources external to the vehicle in which the telephone is installed. A user detector 52 is operably coupled to the telephone controller 504 and configured to provide a signal to the telephone controller 504 indicative of whether the user associated with the telephone is determined to be present in a predetermined location of the vehicle, such that the telephone controller directs a received telephone call for the user to the telephone responsive to the signal. Exemplary user detectors include passive infrared detectors 52c and switching mechanisms 52a, 52b associated with a coupled seatbelt 523 or the user's presence in or near a seat 501.
