ABSTRACT:
A vehicle remote control system includes a remote transmitter to be carried by a user, a receiver at the vehicle for receiving signals from the remote transmitter, an audible signal generator at the vehicle, and a controller connected to the receiver and being operable in response to a received signal. Moreover, the controller is also preferably connected to the audible signal generator for-causing generation of an audible signal based upon a received signal, and wherein the audible signal has at least one characteristic based on the transmission distance so that the audible signal is less intrusive for a shorter transmission distance. For example, the controller may determine the transmission distance based upon the received signal strength. In addition, the at least one characteristic may comprise one or more of a volume, duration, or frequency of the audible signal. The audible signal generation may be used for a vehicle security system, a remote keyless entry system, and/or a remote start system.
