In order to ensure that the software upgrade activities of intelligent networked vehicles comply with the R156 regulations, the R156 regulations are interpreted and an optimization scheme of software upgrade managerment system based on R156 regulation certification system. First ofall, an construction and implementation plan based on the remote update of the software upgrade management system is proposed. The components of RX Software Identification Number (RXSWIN) are described, the electronic control units that are relevant to the regulations are identified, and the software upgrade involving changes to certification parameters should update the RXSWIN. After the vehicles are off the assembly line, the central gateway reads the RXSWIN issued by the software upgrade management system and transmits the initial value to the vehicle for display. In terms of the construction of the software update management system (SUMS), the SUMS management system documents, SUMS management process documents, and related file storage schemes are analyzed, and the documents required for the certification of the SUMS are listed. Finally, according to the requirements of R156 regulations for vehicle type approval (VTA), the model products are thoroughly tested and evaluated, the test items are described. It provides a guidance scheme for the software upgrade management construction for automotive enterprises.
