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: In a vehicle information communication system, a center device includes an individual vehicle configuration information storage unit in which configuration information transmitted from a plurality of vehicles is stored in such a form that transmission timings are specifiable, a campaign information storage unit in which campaign identification information and target vehicle identification information for identifying data update target vehicles are stored as campaign information related to data update for vehicle. The center device refers to the campaign storage unit and the individual vehicle configuration information storage unit, and when there is no transmission of the configuration information from the target vehicle for a predetermined period of time, transmits a message for urging data update to the in-vehicle device of the target vehicle.

Abstract: When configuration information regarding configurations of respective devices are received from electronic control units, the in-vehicle device generates a hash value based on data values of the configuration information, and transmits the hash value to a center device. The center device compares the hash value received from the in-vehicle device with a hash value of configuration information of the vehicle stored in a vehicle-side configuration information storage unit of the center device, and notifies the in-vehicle device of a full data transmission request for transmitting all data values of the configuration information when both of the hash values do not match each other. When the in-vehicle device is notified of the full data transmission request, the in-vehicle device transmits all of the data values of the configuration information to the center device.

Abstract: A data overwriting device includes an overwriting unit that overwrites a part of data stored in a memory, the part in which a difference is generated; a first writing unit that writes first information in a first storage unit when a data overwriting process is completed by the overwriting unit; a second writing unit that writes second information in a second storage unit when confirming that the part of the data overwritten by the overwriting unit includes no error; and a deleting unit that clears the first storage unit storing the first information and the second storage unit storing the second information before the overwriting unit starts executing the data overwriting process.

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.
