Abstract
A center device manages data to be written to a plurality of electronic control devices installed in a vehicle. The center device is configured to generate a package including update data to be distributed to the vehicle; and distribute the package to the vehicle. When an input of information on a master device to which a package is to be distributed is received, the center device identifies an ID corresponding to the master device with reference to a logic ID management registration section on a basis of the information, acquires logic corresponding to the ID from a logic management registration section, and generates a package on a basis of the logic.
Claims3
A center device that manages data to be written to a plurality of electronic control devices installed in a vehicle, the center device comprising:
- a package generation section that is configured to generate a package including update data to be distributed to the vehicle;
- and
- a package distribution section that is configured to distribute the package to the vehicle,
- wherein
- the package generation section includes
- a logic management registration section that registers logic generating the package when the logic is generated according to a specification change of a master device that receives a package distributed from the center device and transfers update data to the electronic control device, and
- a logic identification (ID) management registration section that registers an ID assigned to the logic and a version of software of the master device corresponding to the logic when the ID and the version are notified, and
- when an input of information on a master device to which a package is to be distributed is received from the package distribution section, the package generation section identifies an ID corresponding to the master device with reference to the logic ID management registration section on a basis of the information, acquires logic corresponding to the ID from the logic management registration section, and generates a package on a basis of the logic.
A center device that manages data to be written to a plurality of electronic control devices installed in a vehicle, the center device comprising:
- a package generation section that is configured to generate a package including update data to be distributed to the vehicle;
- and
- a package distribution section that is configured to distribute the package to the vehicle,
- wherein
- the package generation section includes
- a logic management registration section that manages logic generating the package and an ID assigned to the logic, and
- a logic ID management registration section that manages a version of software of a master device and an ID assigned to the logic for the version of the software, and
- when an input of a version of software of a master device to which a package is to be distributed is received as information from the package distribution section, the package generation section identifies an ID corresponding to the master device with reference to the logic ID management registration section on a basis of the information, acquires logic corresponding to the ID from the logic management registration section, and generates a package on a basis of the logic.
A method for generating a distribution package, in which a package including update data to be distributed to a vehicle is generated to write data to a plurality of electronic control devices installed in the vehicle, the method comprising:
- registering logic for generating the package in a logic management registration section when the logic is generated according to a specification change of a master device that receives a package distributed from a center device and transfers update data to the electronic control device;
- registering an ID assigned to the logic and a version of software of the master device corresponding to the logic in a logic ID management registration section when the ID and the version are notified;
- and
- identifying, when an input of information on a master device to which a package is to be distributed is received, an ID corresponding to the master device with reference to the logic ID management registration section on a basis of the information, acquiring logic corresponding to the ID from the logic management registration section, and generating a package on a basis of the logic.
