Abstract

A vehicle includes: a timer measuring a time; a receiver receiving data from a remote control device; a storage storing a unique value of a vehicle, a timer count value of the vehicle, and a timer difference value between the remote control device and the vehicle; and a controller increasing the timer count value of the vehicle after lapse of a predetermined time. In particular, the controller compares a unique value of the remote control device contained in the data with the unique value of the vehicle stored in the storage, and determines whether a user command contained in the data is approved based on a result of the comparison.

First claim

What is claimed is:

1. A vehicle comprising:
a timer configured to measure a time;
a receiver configured to receive data from a remote control device;
a storage configured to store a unique value of a vehicle, a timer count value of the vehicle, and a timer difference value between the remote control device and the vehicle; and
a controller configured to increase the timer count value of the vehicle after lapse of a predetermined time, compare a unique value of the remote control device contained in the data with the unique value of the vehicle stored in the storage, and determine whether a user command contained in the data is approved based on a result of the comparison,
wherein, the controller is configured to approve the user command when the unique value of the vehicle is identical to the unique value of the remote control device, and when a comparison resultant value obtained when a timer difference value stored in the storage is compared with a difference value between the timer count value of the vehicle and a timer count value of the remote control device contained in the data is present in a pre-stored reference range.

2. The vehicle according to claim 1 , wherein
when the unique value of the vehicle is identical to the unique value of the remote control device and a comparison resultant value obtained when a timer difference value stored in the storage is compared with a difference value between the timer count value of the vehicle and the timer count value of the remote control device is present in the pre-stored reference range, the controller stores a difference value between the timer count value of the vehicle and the timer count value of the remote control device, as the timer difference value, in the storage.

3. The vehicle according to claim 1 , wherein
when the unique value of the vehicle is less than the unique value of the remote control device, the controller is configured to allow the unique value of the vehicle stored in the storage to be identical to the unique value of the remote control device.

4. The vehicle according to claim 3 , wherein
when the unique value of the vehicle is less than the unique value of the remote control device, the controller is configured to store a difference value between the timer count value of the vehicle and the timer count value of the remote control device, as the timer difference value, in the storage, and configured to approve the user command.

5. The vehicle according to claim 1 , wherein the receiver is configured to receive the data over a radio frequency (RF) communication network.

6. The vehicle according to claim 1 , wherein
the receiver configured to receive data from a plurality of remote control devices;
the storage configured to store the unique value of the vehicle, the timer count value of the vehicle, and the timer difference value between the remote control device and the vehicle while being classified based on the respective remote control devices; and
the controller configured to determine whether the user command for each remote control device is approved.

7. A remote control device comprising:
an input configured to receive a user command;
a timer configured to measure a time;
a transmitter configured to transmit data including the user command;
a storage configured to store a unique value of a remote control device, a first timer count value, a second timer count value, and a maximum value of the second timer count value; and
a controller configured to increase the first timer count value and the second timer count value after lapse of a predetermined time, and stop operation of the timer after increasing the unique value of the remote control device when the second timer count value reaches the maximum value.

8. The remote control device according to claim 7 , wherein
upon receiving the user command, the controller is configured to operate the timer and control the transmitter to transmit the data.

9. The remote control device according to claim 7 , wherein
upon receiving the user command, the controller is configured to operate the timer, and control the transmitter to transmit data that include the first timer count value, the unique value of the remote control device, and the user command.

10. The remote control device according to claim 7 , wherein
upon receiving the user command, the controller is configured to change the second timer count value stored in the storage to an initial value.

11. The remote control device according to claim 7 , wherein the transmitter is configured to transmit the data through a radio frequency (RF) communication network.

12. The remote control device according to claim 7 , wherein
when an abnormal situation occurs in the remote control device, the controller is configured to change the unique value of the remote control device stored in the storage to an initial value.

13. The remote control device according to claim 7 , wherein the remote control device is a key fob.

14. A method for controlling a vehicle, comprising:
operating, by a controller, a timer;
increasing, by the controller, a timer count value of a vehicle after lapse of a predetermined time;
receiving, by a receiver, data from a remote control device;
comparing, by the controller, a unique value pre-stored in the vehicle with a remote control device's unique value contained in the data; and
determining, by the controller, whether a user command contained in the data is approved based on a result of the comparison,
wherein the determining whether the user command is approved includes:
approving the user command, when the unique value of the vehicle is identical to the unique value of the remote control device, and when a comparison resultant value obtained when a timer difference value pre-stored in the vehicle is compared with a difference value between the timer count value of the vehicle and a timer count value of the remote control device contained in the data is present in a pre-stored reference range.

15. The method according to claim 14 , wherein the determining whether the user command is approved further includes:
when the unique value of the vehicle is identical to the unique value of the remote control device and a comparison resultant value obtained when a timer difference value pre-stored in the vehicle is compared with a difference value between the timer count value of the vehicle and the timer count value of the remote control device contained in the data is present in the pre-stored reference range, storing a difference value between the timer count value of the vehicle and the timer count value of the remote control device as the timer difference value.

16. The method according to claim 14 , wherein the determining whether the user command is approved includes:
when the unique value of the vehicle is less than the unique value of the remote control device, controlling the unique value of the vehicle to be identical to the unique value of the remote control device.

17. The method according to claim 16 , wherein the determining whether the user command is approved includes:
when the unique value of the vehicle is less than the unique value of the remote control device, storing a difference value between the timer count value of the vehicle and the timer count value of the remote control device as the timer difference value, and approving the user command.

18. The method according to claim 14 , wherein
the receiving the data includes receiving data over a radio frequency (RF) communication network.
