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: 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 programed 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.
