Abstract

A vehicle control method according to an embodiments includes: collecting data in a first communication data format from at least one electronic unit in a vehicle; converting the data collected in the first communication data format into a second communication data format in order to be transmitted to a pre-connected destination; transmitting the converted data to the destination; receiving, from the destination, control data of the second communication data format corresponding to the transmitted data; converting the control data of the second communication data format into the first communication data format; and outputting the control data of the first communication data format to a corresponding electronic unit.

Claims

1. A vehicle control method comprising:

collecting data in a first communication data format from at least one electronic unit in a vehicle;

converting the data collected in the first communication data format into a second communication data format in order to be transmitted to a pre-connected destination;

transmitting the converted data to the destination;

receiving, from the destination, control data of the second communication data format corresponding to the transmitted data;

converting the control data of the second communication data format into the first communication data format; and

outputting the control data of the first communication data format to a corresponding electronic unit.

2. The vehicle control method according to claim 1, wherein the first communication data format is a control area network (CAN) communication data format, and the second communication data format is a wireless communication data format.

3. The vehicle control method according to claim 1, wherein the control data converted into the first communication data format is divided into data having a transmission size of the first communication data format, when the control data converted into the first communication data format is output to the corresponding electronic unit.

4. The vehicle control method according to claim 3, wherein a size of the divided data is 8 bytes.

5. The vehicle control method according to claim 1, wherein the collected data is state data of each electronic unit.

6. The vehicle control method according to claim 1, further comprising:

temporarily storing the collected data in the first communication data format; and

converting the stored data into the second communication data format.

7. The vehicle control method according to claim 1, further comprising:

checking information of a monitoring/control device which is the preset destination when a control data reception request is received from the monitoring/control device; and

converting control data received from the monitoring/control device into the second communication data format when the information of the monitoring/control device matches preset destination information.

8. The vehicle control method according to claim 7, wherein the control data received from the monitoring/control device is temporarily stored while the information of the monitoring/control device that has transmitted the control data is checked.

9. The vehicle control method according to claim 8, wherein, when the checking the information of the monitoring/control device is completed, the temporarily stored control data is converted into the second communication data format.

10. A vehicle control device comprising:

a communication unit configured to collect data from at least one electronic unit in a vehicle, convert the collected data into a data format for transmission to a preset destination, collect control data from the outside, and convert the collected control data into a data format for transmission to the electronic unit; and

a control unit configured to control the communication unit so that the data converted by the communication unit is transmitted to the preset destination.

11. The vehicle control device according to claim 10, further comprising a storage unit for storing the collected data.

12. The vehicle control device according to claim 10, further comprising a data conversion unit for converting a data format of the collected data.

13. The vehicle control device according to claim 10, further comprising at least one buffer for temporarily storing the collected data or the converted data.

14. The vehicle control method according to claim 13, wherein the buffer comprises:

a first receiving buffer for temporarily storing the data collected from the electronic units of the vehicle; and

a second receiving buffer for temporarily storing the control data received from the preset external destination.

15. The vehicle control device according to claim 14, wherein the buffer comprises:

a first transmitting buffer for temporarily storing data obtained by converting the data stored in the first receiving buffer; and

a second transmitting buffer for temporarily storing data obtained by converting the data stored in the second receiving buffer.

16. The vehicle control device according to claim 10, wherein the converted control data is divided into data having a transmission size of the converted communication data format, when the converted control data is output to the corresponding electronic unit.
