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.

Abstract: A vehicle information communication system includes a vehicle device and a center device. The center device includes a storage unit, a center computer, and a center-device communication unit. The storage unit stores memory structure information for each of the ECUs. The memory structure information indicates whether a corresponding memory has a memory structure that supports Read While Write (RWW) operation defined as having a plurality of physically independent memory regions. The center computer is programmed to generate specification data including the memory structure information for each of the at least one target ECUs. The vehicle device includes a vehicle computer. The vehicle computer is programmed to perform the program data rewrites of the at least one target ECU according to the memory structure information included in the specification data.

Abstract: A vehicle information communication system including a center apparatus and a vehicle apparatus is provided. The vehicle apparatus is mounted in a vehicle and includes electronic control units (ECUs) each associated with a respective ECU software identifier (SWID). The vehicle apparatus send the ECU SWIDs of the ECUs to the center apparatus via the wireless communications. When all of the ECU SWIDs received from the vehicle apparatus are included in any one of approved ECU SWID combinations and software update data exists for at least one of the ECUs, the center apparatus sends the software update data to the vehicle apparatus via the wireless communications. The vehicle apparatus performs ECU software update based on the software update data sent from the center apparatus.

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.
