Design of Electric Vehicle Drive Motor ECU Control System Based on AUTOSAR

In view of the problem of the Electric vehicle, which is in difficulty and reusability in the development with the permanent magnet motor (PMSM) ECU control system, this paper presented a ECU motor control system development method based on automotive open system architecture (AUTOSAR). It mainly to complete the design of the application layer software components, runnable entities, VFB/RTE layer and basic software layer according to AUTOSAR hierarchical, modularization idea. Bench experiment results showed that the motor ECU control system based on the standard of AUTOSAR, implemented the basic control function of the motor started, accelerated and decelerated in medium and low speed conditions. It will lay a good foundation for the development, transplantation and function expansion on different platforms for auto ECU control system.
