Abstract

An enhanced vehicle remote control system adds a new transmitter and a new receiver to an original remote control system. The new receiver is connected for direct operation of the original transmitter which is permanently installed in the vehicle. In response to signals from the original transmitter, the unmodified original receiver controls the same functions in the same way as before. The new receiver is also connected to control functions in the vehicle which were not controlled by the original remote control system.

Claims

1. A remote control system comprising:

an original remote control system;

said original remote control system including an original transmitter and an original receiver;

said original receiver being connected to enable at least a first function in response to first signals from said original transmitter;

a new transmitter;

a new receiver;

said new receiver including means for producing second and third signals in response to said new transmitter;

means for operating said original transmitter to produce said first signals in response to second signals from said new receiver, whereby said original receiver is operated to enable said at least a first function; and

means for enabling at least a second function, not enabled by said original receiver, in response to said third signal, whereby the ability to enable said second function is added to functions of said original remote control system.

2. A remote control system according to claim 1, further comprising:

means for mounting said original transmitter in fixed relationship to said new receiver in a vehicle;

said original receiver being mounted in said vehicle;

said new transmitter being portable; and

said new receiver being responsive only to signals from said new transmitter;

said original receiver being responsive only to signals from said original transmitter; and

said original receiver being substantially unmodified.

3. A remote control system according to claim 2, wherein said means for mounting said original transmitter includes a compartment in said new receiver for containing said original transmitter.

4. A remote control system according to claim 1, wherein said means for operating said original transmitter includes electrical connection from said new receiver to responsive portions of said original transmitter, whereby original functions of said original transmitter are operable directly by said new receiver, and said original receiver is thereby enabled to perform its original functions.

5. An enhancement to an original remote control system, wherein said original remote control system includes an original transmitter and an original receiver, with said original receiver being connected to perform at least a first function in response to reception of a first signal from said original transmitter, comprising:

a new receiver;

a new transmitter effective for communicating with said new receiver;

first means associated with said new receiver for controlling said original transmitter to enable performance of said at least a first function; and

second means associated with said new receiver for performing at least a second function not performed by said original remote control system.

6. A system according to claim 5, wherein:

said new receiver, said original receiver and said original transmitter are mounted in a vehicle; and

said original transmitter is powered from a power source of said vehicle.
