Abstract

A remote control system for a vehicle may include a transponder configured to communicate with a mobile device, and a controller comprising a processing unit. The processing unit may be configured to: receive a control request to perform a vehicle function from the mobile device; receive an authentication signal from the mobile device, the authentication signal being generated by the transponder; and perform the vehicle function based on the authentication signal.

First claim

What is claimed is:

1 . A remote control system for a vehicle, the remote control system comprising:
a transponder configured to communicate with a mobile device; and a controller comprising a processing unit configured to:
receive a control request to perform a vehicle function from the mobile device;
receive an authentication signal from the mobile device, the authentication signal being generated by the transponder; and
perform the vehicle function based on the authentication signal.

2 . The remote control system of claim 1 ,
wherein the transponder is configured to communicate with the mobile device over a short-range wireless network, and wherein the controller is configured to communicate with the mobile device over a long-range wireless network.

3 . The remote control system of claim 2 , wherein the short-range wireless network includes a Bluetooth™ network, and the long-range wireless network includes a cellular network.

4 . The remote control system of claim 1 , wherein the transponder is paired with the controller based on a security key stored in the transponder and the controller.

5 . The remote control system of claim 4 , wherein the security key is not accessible to the mobile device.

6 . The remote control system of claim 1 , wherein the processing unit is further configured to generate a challenge, the challenge being transmitted to the transponder by way of the mobile device, and the authentication signal being an expected response to the challenge.

7 . The remote control system of claim 6 , wherein the processing unit is further configured to determine a valid response to the challenge.

8 . The remote control system of claim 7 , wherein the processing unit is further configured to compare the expected response to the valid response, and perform the vehicle function based on the expected response matching the valid response.

9 . The remote control system of claim 1 ,
wherein the transponder further includes an input, and wherein the performing the vehicle function is based on an actuation of the input.

10 . The remote control system of claim 1 , wherein the vehicle function includes at least one of turning the vehicle on, unlocking a door, operating a powertrain, or operating a steering column of the vehicle.

11 . A method of remote control for a vehicle, the method comprising:
receiving, by a controller, a control request to perform a vehicle function from a mobile device, the mobile device being in communication with a transponder; receiving, by the controller, an authentication signal from the mobile device, the authentication signal being generated by the transponder; and performing the vehicle function based on the authentication signal.

12 . The method of claim 11 ,
wherein the transponder is configured to communicate with the mobile device over a short-range wireless network, and wherein the controller is configured to communicate with the mobile device over a long-range wireless network.

13 . The method of claim 12 , wherein the short-range wireless network includes a Bluetooth™ network, and the long-range wireless network includes a cellular network.

14 . The method of claim 11 , further including pairing the transponder with the controller based on a security key stored in the transponder and the controller.

15 . The method of claim 14 , further including preventing access of the mobile device to the security key.

16 . The method of claim 11 , further including:
generating, by the controller, a challenge; and transmitting the challenge to the transponder by way of the mobile device, and the authentication signal being an expected response to the challenge.

17 . The method of claim 16 , further including determining, by the controller, a valid response to the challenge.

18 . The method of claim 17 , further including comparing, by the controller, the expected response to the valid response, and performing the vehicle function based on the expected response matching the valid response.

19 . The method of claim 11 , wherein the performing the function includes at least one of turning the vehicle on, unlocking a door, operating a powertrain, or operating a steering column of the vehicle.

20 . A non-transitory computer-readable medium storing instructions which, when executed, cause one or more processors to perform a method of remote control of a vehicle, the method comprising:
receiving a control request to perform a vehicle function from a mobile device, the mobile device being in communication with a transponder; receiving an authentication signal from the mobile device, the authentication signal being generated by the transponder; and performing the vehicle function based on the authentication signal.
