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 method for a vehicle control system, the method comprising:

collecting, via a communication unit in the vehicle, data in a first communication data format from any of a plurality of electronic units located in the vehicle, wherein the data comprises operational and state data of an electronic unit among the plurality of electronic units;

storing the collected data in the first communication data format in a first receiving buffer memory;

converting the data stored in the first communication data format into a second communication data format in order to be wireless transmitted to a device that is physically external to the vehicle;

storing the converted data in the second communication data format in a second receiving buffer memory;

wirelessly transmitting, via a wireless communication unit in the vehicle, the stored data in the second receiving buffer memory to the device;

receiving, via the wireless communication unit, control data in the second communication data format from the device, wherein the control data corresponds to the stored data that was wirelessly transmitted;

storing the received control data in the second communication data format in a first transmitting buffer memory;

converting the received control data in the second communication data format into the first communication data format by dividing the received control data into plural data each having a communication size that is a maximum communication size of the first communication data format;

storing the plural data comprising the converted control data in the first communication data format in a second transmitting buffer memory;

outputting the plural data comprising the converted control data in the first communication data format that is stored in the second transmitting buffer memory to the communication unit; and

communicating, via the communication unit in the vehicle, the plural data in the first communication data format to the electronic unit within the vehicle.

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 maximum communication size of the first communication data format is 8 bytes.

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

checking information of the device when a control data reception request is received from the device; and

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

5. The vehicle control method according to claim 4, wherein the control data received from the device is temporarily stored while the information of the device is checked.

6. The vehicle control method according to claim 5, wherein, when the checking the information of the device is completed, the temporarily stored control data is converted into the second communication data format.

7. A vehicle control system for a vehicle, the system comprising:

a communication unit configured to collect data in a first communication data format from any of a plurality of electronic units located in the vehicle, wherein the data comprises operational and state data of an electronic unit among the plurality of electronic units;

a first receiving buffer memory;

a second receiving buffer memory;

a first transmitting buffer memory;

a second transmitting buffer memory;

a data conversion unit;

a wireless communication unit; and

a controller configured to;

control the data conversion unit to convert the data stored in the first communication data format into a second communication data format in order to be wirelessly transmitted to a device that is physically external to the vehicle;

store the converted data in the second communication data format in the second receiving buffer memory;

wirelessly transmit, via the wireless communication unit, the stored data in the second receiving buffer memory to the device;

receive, via the wireless communication unit, control data in the second communication data format from the device, wherein the control data corresponds to the stored data that was wirelessly transmitted;

store the received control data in the second communication data format in the first transmitting buffer memory;

convert the control data in the second communication data format into the first communication data format by dividing the received control data into plural data each having a communication size that is a maximum communication size of the first communication data format;

store the plural data comprising the converted control data in the first communication data format in the second transmitting buffer memory;

output the plural data comprising the converted control data in the first communication data format that is stored in the second transmitting buffer memory to the communication unit; and

communicate, via the communication unit, the plural data in the first communication data format to the electronic unit within the vehicle.

8. The system of claim 7, 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.

9. The system of claim 7, wherein the maximum communication size of the first communication data format is 8 bytes.

10. The system of claim 7, wherein the controller is further configured to:

check information of the device when a control data reception request is received from the device; and

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

11. The system of claim 10, wherein the control data received from the device is temporarily stored while the information of the device is checked.

12. The system of claim 11, wherein when the checking the information of the device is completed, the temporarily stored control data is converted into the second communication data format.
