Abstract: An electronic control system for vehicle includes a center device that manages a program update of a vehicle, and a vehicular master device that is communicable with the center device. The center device, responsive to a user giving approval for program update by using a device not being a possession owned by the user, receives approval information of the user, and stores and manages the approval information in association with vehicle information of the user. The center device transmits the approval information to the user's vehicle side. When the vehicular master device receives the approval information, the vehicular master device performs rewriting of the program.

Abstract: An onboard communication system includes a center device that transmits update data as a distribution package by a streaming manner to an electronic control unit installed in a vehicle, a master device that is installed in the vehicle and receives the distribution package and transfer the update data to the electronic control unit, and the electronic control unit that writes the update data transferred from the master device to a storage unit. The center device also transmits a hash value calculated for the update data to the master device. The electronic control unit calculates a hash value for the update data and transmits the hash value to the master device. The master device compares the hash value transmitted from the center device with the hash value transmitted from the electronic control unit to verify integrity of the update data.

Abstract: An electronic control unit includes an installation execution unit that operates at least one of an application program or parameter data stored in a first data storage bank serving as an active bank and rewrites a second data storage bank serving as an inactive bank by writing, to the second data storage bank, update data acquired from an external device, and an activation execution unit that switches the active bank from the first data storage bank to the second data storage bank. The installation execution unit rewrites the second data storage bank during a vehicle being travelable or parked. The activation execution unit switches the active bank from the first data storage bank to the second data storage bank during the vehicle being parked.

Abstract: In a vehicle electronic control system, a center device includes an update data storage unit that stores update data for rewrite targets. Program rewriting to rewrite target electronic control units is one campaign. The center device includes a display control information storage unit that stores display control information necessary to display information related to the campaign on a vehicle side. The center device transmits the update data stored in the update data storage unit and the display control information stored in the display control information storage unit to a vehicle master device.

Abstract: A display control device includes a cancellation detection unit that is configured to detect a cancellation regarding a program rewrite from first update data stored in the rewrite target ECU to second update data acquired from an external device, a write instruction unit that is configured to distribute the second update data to the rewrite target ECU and instruct the rewrite target ECU to write the second update data thereinto, and a notification instruction unit that is configured to give an instruction for notification of a progress regarding the program rewrite. The notification instruction unit is further configured to give the instruction to make the notification of the progress regarding the program rewrite in a first manner when the write instruction unit is distributing the second update data, and give the instruction to make the notification of the progress regarding the program rewrite in a second manner when the cancellation detection unit detects the cancellation. The write instruction unit is further configured to continue distributing the second update data when the cancellation detection unit detects the cancellation during distribution of the second update data by the rewrite instruction unit.

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.

Abstract: A center device that manages data to be written in an electronic control device and performs, by an application program, functions to transmit update data to a vehicle by wireless communication is provided. An application program implementing at least one of the functions adopts a serverless architecture. The application program is activated upon occurrence of an event and is dynamically allocated with a resource in an on-demand manner for execution of a code of the application program. The resource is released when the execution of the code is terminated. The center device is configured to receive vehicle configuration information and determine whether there is campaign information; generate campaign notification information; manage a generation state of the campaign notification information; and distribute the campaign notification information.
