- Project：DOIT Program
- Category：Vehicles diagnosis technology
- Technique Features：
This technology provides software complying with standard communication protocol of diagnostic services for road vehicles. It consists of diagnostic software inside on-vehicle electronic control units and external testing software. All the software implementations are based on international standards, including ISO 14229-1 and ISO 15765-2. Tester and ECU verify SEED/KEY for security, then Tester communication with ECU by following ISO 14229-1, and execute the flash bootloader flow. Update and execute new application by loading application data with Controller Area Network(CAN). To avoid accident execute in normal execute, the flash driver load into ECU before every update step, and to avoid execute uncompleted application, the check sum will calculate and check after ever data transfer. We follow ISO 15765-2 for information packaging, message dividing and transmission. This technology can help the development of flash bootloader for road vehicles.
