Abstract

A communication module, a vehicle including the same, and a method for controlling the vehicle can solve a timing issue encountered when signals for the same service are communicated between different communication schemes, thereby guaranteeing stability in a telematics remote service. The vehicle includes a first communication unit configured to perform wired communication; a second communication unit configured to perform wireless communication to receive a remote signal; a control unit configured to generate a communication signal by adding a wake-up signal to a drive command signal of the received remote signal upon receiving the remote signal from the second communication unit, and to transmit the generated communication signal to the first communication unit; and a drive unit configured to receive the communication signal from the first communication unit, and to drive load on the basis of a drive command signal of the received communication signal.

Claims

1. A vehicle comprising:

a first communication unit configured to perform wired communication;

a second communication unit configured to perform wireless communication to receive a remote signal;

a control unit configured to generate a communication signal by adding a wake-up signal to a drive command signal of the received remote signal upon receiving the remote signal from the second communication unit, and to transmit the generated communication signal to the first communication unit; and

a drive unit configured to receive the communication signal from the first communication unit, and to drive load on the basis of a drive command signal of the received communication signal,

wherein the first communication unit includes;

a gateway;

at least one first CAN communication unit configured to interconnect the control unit and the gateway; and

at least one second CAN communication unit configured to interconnect the drive unit and the gateway, and

wherein the at least one first CAN communication unit transmits a copied signal obtained by duplication of the communication signal.

2. The vehicle according to claim 1, wherein the control unit determines a specific time before a predetermined time on the basis of a transmission time of the drive command signal to be a transmission time of the wake-up signal.

3. The vehicle according to claim 1, wherein the control unit generates a predetermined number of communication signals, each of which includes the wake-up signal and the drive command signal.

4. The vehicle according to claim 1, wherein the control unit awakes upon reception of the remote signal, and then transmits a wake-up signal to the first communication unit.

5. The vehicle according to claim 1, wherein the gateway receives a communication signal from the at least one first CAN communication unit, and transmits a wake-up signal contained in the communication signal to the at least one second CAN communication unit.

6. The vehicle according to claim 5, wherein:

after lapse of a predetermined time after the gateway transmits the wake-up signal, the gateway transmits the drive command signal to the at least one second CAN communication unit.

7. The vehicle according to claim 5, wherein the at least one second CAN communication unit performs a wake-up operation upon receiving the wake-up signal, and transmits a drive command signal to the drive unit upon receiving the drive command signal.

8. The vehicle according to claim 1, wherein the gateway further transmits a predetermined number of communication signals to the at least one second CAN communication unit at intervals of a predetermined time.

9. The vehicle according to claim 1, wherein each of the at least one first CAN communication unit and the at least one second CAN communication unit includes a communication speed equal to or less than a predetermined speed.

10. The vehicle according to claim 1, wherein the remote signal includes any one of a remote starting signal, a remote door opening/closing signal, a remote air-conditioning adjustment signal, and a remote lighting signal.

11. A communication module comprising:

a first CAN communication unit connected to an external control unit for receiving a remote signal, configured to receive a communication signal from the external control unit;

a second CAN communication unit connected to drive a load; and

a gateway connected to the first CAN communication unit and the second CAN communication unit, configured to receive the communication signal from the first CAN communication unit and to transmit the received communication signal to the second CAN communication unit,

wherein the communication signal includes a wake-up signal and a load drive command signal contained in the remote signal, and

wherein the first CAN communication unit transmits a copied signal obtained by duplication of the communication signal.

12. The communication module according to claim 11, wherein the gateway transmits the wake-up signal to the second CAN communication unit, and transmits the drive command signal after lapse of a predetermined time.

13. A communication module comprising:

a gateway;

a first CAN communication unit configured to receive a communication signal from an external control unit, to awake by a wake-up signal of the received communication signal and to transmit a drive command signal of the received communication signal to the gateway; and

a second CAN communication unit configured to connect a drive unit for driving a load to the gateway,

wherein the gateway generates the wake-up signal upon receiving the drive command signal, transmits the generated wake-up signal to the second CAN communication unit, and transmits the received drive command signal to the second CAN communication unit after lapse of a predetermined time, and

wherein the first CAN communication unit transmits a copied signal obtained by duplication of the received communication signal.

14. The communication module according to claim 13, wherein the gateway further transmits the wake-up signal and the drive command signal to the second CAN communication unit at intervals of the predetermined time.

15. The communication module according to claim 13, wherein each of the first CAN communication unit and the second CAN communication unit includes a communication speed equal to or less than a predetermined speed.

16. The communication module according to claim 13, wherein the second CAN communication unit performs a wake-up operation upon receiving the wake-up signal, and transmits the received drive command signal to the drive unit upon receiving the drive command signal.

17. The communication module according to claim 13, wherein the gateway retransmits the wake-up signal when the second CAN communication unit is deactivated.
