Abstract

A system for remote starting a vehicle equipped with a keyless go system. The keyless go system is adapted to start the vehicle upon receipt of a proper response to a challenge emitted by the keyless go system, the response being computed by a key fob. A first interface is located proximate the keyless go system, the first interface being adapted to relay the challenge from the keyless go system to a second interface, and to receive the response from the second interface and relay the response to the keyless go system. A second interface is located proximate the key fob, the second interface being adapted to receive the challenge and relay the challenge to the key fob and being adapted to receive the response and relay the response to the first interface. The car can be remote started from a distant location, without having to disable the on-board security system of the car.

Claims

1. In a vehicle equipped with a keyless go system, a method for remote starting the vehicle comprising the steps of:

providing a first interface, the first interface being located inside the vehicle and proximate the keyless go system, the first interface being adapted to communicate with the keyless go system through a first low frequency transceiver and a first high frequency transceiver, and being further provided with a second high frequency transceiver;

providing a second interface, the second interface being located proximate a key fob linked to the vehicle, the second interface being adapted to communicate with the key fob through a second low frequency transceiver and a third high frequency transceiver, and being further provided with a fourth high frequency transceiver;

capturing a challenge emitted by the keyless go system with the first low frequency transceiver;

converting the challenge into a format adapted to be transmitted by the second high frequency transceiver;

receiving the challenge with the fourth high frequency transceiver;

converting the challenge from the fourth high frequency transceiver for transmission by the second low frequency transceiver;

at the key fob

receiving the challenge;

computing a response thereto; and

emitting the response;

receiving the response with the third high frequency transceiver;

converting the response into a format adapted to be transmitted by the fourth high frequency transceiver;

receiving the response with the second high frequency transceiver;

converting the response from the second high frequency transceiver for transmission by the first high frequency transceiver;

delivering the response to the keyless go system; and

if the response is a proper response to the challenge, initiating the starting of the vehicle by the keyless go system.

2. A system for remote starting a vehicle equipped with a keyless go system, the keyless go system being adapted to start the vehicle upon receipt of a proper response to a challenge emitted by the keyless go system, the response being computed by a key fob, the system comprising:

a. a first interface located proximate the keyless go system, and including a first low frequency transceiver, a first high frequency transceiver and a second high frequency transceiver;

b. a second interface located proximate the key fob, the second interface including a second low frequency transceiver, a third high frequency transceiver and a fourth high frequency transceiver;

the first interface being adapted to capture the challenge with the first low frequency transceiver and emit the challenge through the second high frequency transceiver; and

to receive the response through the second high frequency transceiver and forward the response to the keyless go system through the first high frequency transceiver;

the second interface being adapted to receive the challenge through the fourth high frequency transceiver and to forward the challenge to the keyfob through the second low frequency transceiver; and

to receive the response with the third high frequency transceiver and to emit the response through the fourth high frequency transceiver.

3. A system according to claim 2, wherein the first and second high frequency transceivers are a single unit and wherein the third and fourth high frequency transceivers are a single unit.

4. A system according to claim 2, wherein the first and third high frequency transceivers are adapted to communicate on a frequency identical to a frequency of the key fob.

5. A system according to claim 2, wherein the second and fourth high frequency transceivers are adapted to communicate on a same frequency.

6. A system according to claim 5, wherein the same frequency is a frequency identical to the frequency of the key fob.

7. A system according to claim 2, wherein a range of communication between the first and second interfaces is greater than a range of communication between the keyless go system and the key fob.

8. A system according to claim 2, wherein the challenge is a same challenge each time.

9. A system according to claim 2, wherein the challenge is different from time to time.

10. A system for remote starting a vehicle equipped with a keyless go system, the keyless go system being adapted to start the vehicle upon receipt of a proper response to a challenge emitted by the keyless go system, the response being computed by a key fob, the system comprising:

a. a first interface located proximate the keyless go system, the first interface being adapted to relay the challenge from the keyless go system to a second interface, and to receive the response from the second interface and relay the response to the keyless go system;

b. the second interface being located proximate the key fob, the second interface being adapted to receive the challenge and relay the challenge to the key fob and being adapted to receive the response and relay the response to the first interface.

11. A system for remote starting a vehicle equipped with a keyless go system, the keyless go system being adapted to start the vehicle upon receipt of a proper response to a challenge emitted by the keyless go system, where the challenge C is a constant challenge, the system comprising:

a. a first interface located proximate the keyless go system, the first interface for storing at least one response to the challenge, and to receive the response from the second interface and relay the response to the keyless go system;

b. the second interface being located proximate the key fob, the second interface having a memory for storing the challenge, and being adapted to relay the challenge to the key fob and being adapted to receive the response and relay the response to the first interface;

wherein when a user actuates the second interface to remote start the vehicle, the first interface triggers the keyless go system into issuing the challenge, and subsequently relays the response stored in memory to the keyless go system in order to effect remote starting of the vehicle.
