Remote control system for a vehicle
View Patent ↗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.
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:
detect a condition from the vehicle;
generate a notification in response to the detected condition;
transmit the notification to the mobile device;
receive an authentication signal from the mobile device in response to the notification, the authentication signal being generated by the transponder; and
perform a 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 comprises near field communication, 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: a controller of the vehicle
detecting a condition from the vehicle;
generating a notification in response to the detected condition;
transmitting the notification to a mobile device;
receiving an authentication signal from the mobile device in response to the notification, the authentication signal being generated by a 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 comprises near field communication, 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:
detecting a condition from the vehicle;
generating a notification in response to the detected condition;
transmitting the notification to a mobile device;
receiving an authentication signal from the mobile device in response to the notification, the authentication signal being generated by the transponder; and
performing the vehicle function based on the authentication signal.
