| Abstract: The integration function of ECU (Electronic Control Unit) automotive electronic control unit is increasingly complex.In order to cope with software update and the demand for bootloader,this paper uses LabVIEW programming language,adopts CAN bus communication technology,follows UDS protocol specification,and writes according to Bootloader data brushing to designed a LabVIEW-based automotive ECU to refresh the host computer software.The upper computer integrates all the diagnostic services in the process of data writing,provides a simple and easy-to-operate human-computer interaction interface,achieves the online program update function,and can complete the task of car ECU program refreshing well.The test results show that the CAN network test tool and the host computer interface can successfully implement the frequent flashing and writing update program.It has been used in the real program flash writing operation,and has high reliability and effectiveness. |
