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: A vehicle information communication system includes a center apparatus and a vehicle apparatus that includes a group of electronic control units (ECUs) and that sends vehicle configuration information including configuration information on the group of ECUs mounted in the vehicle to the center apparatus via wireless communications. The center apparatus performs a first determination of whether the vehicle configuration information received from the vehicle apparatus matches approved-configuration information registered in an approved-configuration database, and performs a second determination of whether software update data for at least one ECU of the group of ECUs mounted in the vehicle exists in an update database. When both the first and second determinations are true, the center apparatus sends the software update data for at least one ECU of the group of ECUs mounted in the vehicle to the vehicle apparatus via the wireless communications.

Abstract: 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.

Abstract: In a vehicle electronic control system, an electronic control device (ECU) is configured to rewrite a program by writing the update data received from the vehicle master device in a non-volatile memory. Incomplete provisional software is written in a write area of the non-volatile memory in the ECU. The vehicle master device includes: a specific mode determination unit that is configured to determine whether a specific mode for controlling a sequence of a program update is set; and a rewrite instruction unit that is configured to instruct the rewrite target ECU to write the update data under the specific mode when the specific mode determination unit determines that the specific mode is set.

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: In an ECU reprogram data DB of a center device, data of an update program for a target ECU for a program update among a plurality of EUCs mounted in a vehicle is stored. In a configuration information DB, an “ECU ID” corresponding to each ECU and vehicle-related information such as an “ECU SW ID” for each application program stored in the ECU are stored along with the vehicle type. An ECU metadata database stores update data-related information pertaining to update data and attributes of the rewrite target ECU. A specification data generation unit generates specification data, based on the information stored in the configuration information database and the information stored in the ECU metadata database, to be transmitted to the vehicle together with update data to be written in the target ECU such that the data includes information related to the type, attributes, and update data for the target ECU and information indicative of a rewrite environment related to the data update.
