Abstract

A vehicle includes: a first electronic module transmitting one data object of new data and comparison data indicating a difference between the new data and existing data when transmission of the new data is requested; a second electronic module receiving the comparison data, acquiring the new data from the comparison data, and controlling at least one operation of the vehicle based on the acquired new data; and a bus transferring data between the first electronic module and the second electronic module.

Claims

1. A vehicle comprising:

a first electronic module transmitting one data object of new data and comparison data indicating a difference between the new data and existing data when transmission of the new data is requested;

a second electronic module receiving the comparison data, acquiring the new data from the comparison data, and controlling at least one operation of the vehicle based on the acquired new data; and

a bus transferring data between the first electronic module and the second electronic module.

2. The vehicle according to claim 1, wherein, when there is no difference between the new data and the existing data, the second electronic module controls the at least one operation of the vehicle based on the existing data.

3. The vehicle according to claim 1, wherein the first electronic module calculates the difference between the new data and the existing data.

4. The vehicle according to claim 3, wherein the first electronic module creates the comparison data to include information indicating whether there is a difference between the new data and the existing data and information indicating an amount of the difference when the difference exists.

5. The vehicle according to claim 4, wherein the information indicating whether there is a difference between the new data and the existing data and the information indicating the amount of the difference are stored in a predetermined data field in the comparison data.

6. The vehicle according to claim 4, wherein the first electronic module determines a size of the comparison data according to the amount of the difference.

7. The vehicle according to claim 4, wherein the first electronic module creates the comparison data to include a control register determined according to the amount of the difference.

8. The vehicle according to claim 7, wherein the second electronic module interprets the comparison data including the control register to acquire the new data.

9. The vehicle according to claim 1, wherein each of a data field of the new data, a data field of the existing data, and a data field of the comparison data is a maximum of 64 bits.

10. The vehicle according to claim 1, wherein, when the comparison data is transmitted by the first electronic module a predetermined number of times or more, the first electronic module transmits the new data.

11. An electronic module comprising:

a communication unit communicating with an external electronic module through an in-vehicle communication network; and

a controller controlling operation of the communication unit, causing the communication unit to transmit one data object of new data and comparison data indicating a difference between the new data and existing data when transmission of the new data is requested,

wherein the controller interprets the comparison data to acquire the new data and controls at least one operation of a vehicle based on the acquired new data.

12. The electronic module according to claim 11, wherein, when there is no difference between the new data and the existing data, the controller controls the at least one operation of the vehicle based on the existing data.

13. The electronic module according to claim 11, wherein the controller calculates the difference between the new data and the existing data.

14. The electronic module according to claim 13, wherein the controller creates the comparison data to include information indicating whether there is a difference between the new data and the existing data and information indicating an amount of the difference when the difference exists.

15. The electronic module according to claim 14, wherein the information indicating whether there is a difference between the new data and the existing data and the information indicating the amount of the difference are stored in a predetermined data field in the comparison data.

16. The electronic module according to claim 14, wherein the controller determines a size of the comparison data according to the amount of the difference.

17. The electronic module according to claim 14, wherein the controller module creates the comparison data to include a control register determined according to the amount of the difference.

18. The electronic module according to claim 17, wherein the controller interprets the comparison data including the control register to acquire the new data.

19. The electronic module according to claim 11, wherein, when the comparison data is transmitted by the controller a predetermined number of times or more, the controller transmits the new data.

20. The electronic module according to claim 11, wherein each of a data field of the new data, a data field of the existing data, and a data field of the comparison data is a maximum of 64 bits.

21. A communication method in a vehicle, the method comprising:

transmitting, by a first electronic module, one data object of new data and comparison data indicating a difference between the new data and existing data when transmission of the new data is requested;

receiving, by a second electronic module, the comparison data;

acquiring, by the second electronic module, the new data from the comparison data; and

controlling, by the second electronic module, at least one operation of the vehicle based on the acquired new data,

wherein data is transferred between the first electronic module and the second electronic module using a bus.
