摘要： 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.

摘要： 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.

摘要： 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.

摘要： A gateway device includes a request receiving portion receiving, from diagnosis purpose tools, diagnosis requests for performing malfunction diagnosis to an ECU of a vehicle, an outputting portion outputting the diagnosis request to an in-vehicle LAN, a response receiving portion receiving a diagnosis response output from the ECU to the in-vehicle LAN as a response to the diagnosis request, a transmitting portion transmitting the diagnosis response to corresponding diagnosis purpose tool, and an arbitration portion. When the request receiving portion receives anon-prioritized diagnosis request from a non-prioritized diagnosis purpose tool at a previous time and receives a prioritized diagnosis request from a prioritized diagnosis purpose tool before an end of the malfunction diagnosis requested by the non-prioritized tool, the arbitration portion cancels an output of the non-prioritized diagnosis request from the outputting portion cancels a transmission of the non-prioritized diagnosis response from the transmitting portion to the non-prioritized tool.

摘要： A vehicle-mounted control system to prevent an execution of an improper request of a center apparatus is provided. The vehicle-mounted control system executes an impropriety determination process, which determines whether a center request signal is an improper signal, based on circumstance information representing a circumstance where a vehicle is placed. Accordingly, it may be possible to determine whether the center request signal is an improper signal transmitted by an operation of a center apparatus by an improper person. When it is determined as the improper center request signal (S2: No), a vehicle control based on the center request signal is not executed.
