change a content of the executed arithmetic processing based on an identification result of the type of the trailer to change the travel control of the vehicle.

3. The electronic control unit according to claim 2 , wherein the instructions cause the one or more processors to:

execute the acquired program to change the content of the executed arithmetic processing.

4. The electronic control unit according to claim 3 , wherein the instructions cause the one or more processors to:

transmit trailer identification information indicating the type of the trailer to an external server using a transmission device connected to the electronic control unit, and

acquire a program corresponding to the type of the trailer transmitted from the server according to the trailer identification information.

5. The electronic control unit according to claim 2 , wherein

the electronic control unit is configured using a reconfigurable arithmetic processing circuit in which a plurality of logic circuits are combined, and

the instructions cause the one or more processors to acquire circuit information corresponding to the type of the trailer identified, and reconfigure the arithmetic processing circuit using the acquired circuit information to change the content of the executed arithmetic processing.

6. The electronic control unit according to claim 5 , wherein

the one or more memory devices store a plurality of types of circuit information for reconfiguring the arithmetic processing circuit, and

wherein the instructions cause the one or more processors to acquire circuit information corresponding to the type of the trailer from among the plurality of types of circuit information stored in the one or more memory devices.

7. The electronic control unit according to claim 5 , wherein the instructions cause the one or more processors to:

transmit trailer identification information indicating the type of the trailer to an external server using a transmission device connected to the electronic control unit, and

acquire circuit information corresponding to the type of the trailer transmitted from the server according to the trailer identification information.

8. The electronic control unit according to claim 2 , wherein the instructions cause the one or more processors to acquire an identifier corresponding to the type of the trailer from the trailer, and identify the type of the trailer based on the acquired identifier.

9. The electronic control unit according to claim 2 wherein the instructions cause the one or more processors to identify the type of the trailer based on input information from a user.

10. The electronic control unit according to claim 2 , wherein the instructions cause the one or more processors to identify the type of the trailer based on the sensor information.

11. The electronic control unit according to claim 1 , wherein the instructions cause the one or more processors to:

acquire sensor information corresponding to a surrounding environment of the trailer and execute arithmetic processing related to travel control of the vehicle based on the acquired sensor information, the sensor information being output from a sensor attached to the trailer; and

acquire processing information corresponding to the type of the trailer from the trailer, and change a content of the executed arithmetic processing based on the acquired processing information to change the travel control of the vehicle.

12. The electronic control unit according to claim 2 , wherein the type of the trailer is set based on at least one of a type, a number, and an attachment position of the sensor.

13. The electronic control unit according to claim 1 , wherein

when the trailer is not connected to the vehicle, sensor information corresponding to a surrounding environment of the vehicle is acquired, the sensor information being output from a sensor attached to the vehicle, and

travel control of the vehicle is changed so as to perform the travel control of the vehicle based on the acquired sensor information.

14. The electronic control unit according to claim 1 , wherein a user is notified of a travel control mode of the vehicle set according to the type of the trailer.

15. An electronic control unit installed on a vehicle, the electronic control unit comprising one or more memory devices storing instructions thereon, that, when executed by one or more processors, cause the one or more processors to:

identify, based on sensor information output from a sensor, whether a trailer is connected to the vehicle;

identify, based on the sensor information output from the sensor, a type of chassis of the vehicle;

identify a program corresponding to the type of chassis of the vehicle from among a plurality of programs stored in the one or more memory devices; and

execute the identified program to change a travel control of the vehicle.
