A vehicular electronic control device installed in a vehicle capable of switching between a chargeable state and an unchargeable state performs activation acceptance for inquiring of a user whether to accept activation processing of activating updated software after completion of installation processing of writing update data in an update target node to generate the updated software, transmits during the chargeable state a switching instruction that executes the activation processing during the chargeable state to the update target node, and transmits during the chargeable state a switching setting instruction that executes the activation processing during the unchargeable state to the update target node.

Vehicular electronic control device and update program

A center device includes an update data storage unit in which new data and new difference data for updating to the new data from old data are stored for, among electronic control units mounted on a vehicle, a target device targeted for data update. The center device generates, using the new data, a first verification value for verifying integrity in the vehicle, and generates, using the new difference data, a second verification value for verifying integrity of the new difference data in the vehicle. The center device generates a package including the new difference data, the first verification values and the second verification values for a plurality of the target devices. The center device generates, using the distribution package, a third verification value for verifying integrity of the distribution package in the vehicle, and transmits the distribution package along with the third verification value to the in-vehicle device.

Distribution package generation device, distribution package communication system, distribution package transmission method, and storage medium

A center device includes a database storing a plurality of information items regarding a vehicle. The center device identifies a vehicle state by integrating the plurality of information items stored in the database. The center device generates visualization information to be displayed by a display device from an identification result of the vehicle state. The center device transmits the visualization information to the display device.

Center device, identification result display system for vehicle state, non-transitory tangible computer readable storage medium, and identification result transmission method for vehicle state

A center device is configured to: acquire behavior data indicating a behavior of a user; store the behavior data; acquire vehicle state data indicating a vehicle state; store the vehicle state data; create a distribution plan of reprogramming data to be distributed to vehicle devices of the vehicle by using the behavior data and the vehicle state data; and distribute the reprogramming data to the vehicle devices according to the created distribution plan.

Center device, reprogramming data distribution system, and reprogramming data distribution plan creation program product

The center device includes: a first wireless communication unit configured to wirelessly communicate with a vehicle using a first communication method within a first communication range; a second wireless communication unit configured to wirelessly communicate with the vehicle using a second communication method having a higher communication speed than that of the first communication method within a second communication range which is smaller than the first communication range; a reception control unit configured to control a reception of vehicle information from the vehicle to the first wireless communication unit; and a distribution control unit configured to control distribution of content data from the second wireless communication unit to the vehicle according to the vehicle information.

Center device, data communication system, and data communication program product

A center device is provided that manages data to be written to electronic control units mounted on a vehicle. The center device includes an update data storage unit that stores update data for a data update target device among the electronic control units. The center device distributes the update data to the vehicle. The center device includes an individual vehicle configuration information storage unit that stores identification information of target vehicles targeted for update using the update data, and update status information regarding update completion status and update-in-progress status acquired as update status from target vehicles. The center device manages the update status information of the target vehicles in a statistically tabulatable manner on basis of the update status information.
