According to reports, “Autosar†is an open system architecture commonly used by international mature car makers. Auto parts manufacturers need to develop systems that meet Autosar's requirements in order to enter the supply chain system of mainstream car manufacturers. The system needs to be from the chip level and the software level. At the tool chain level and even a series of supporting support.
Infineon Technologies, as the leading automotive semiconductor supplier in the industry, has accumulated rich experience in Autosar. In the motor controller prototype, the MCAL Drivers: MC-ISAR low-level code of the Aurix series of microcontrollers provided by Infineon provides strong support for the development of the Sino-German College of Tongji University. In addition, the Aurix product family offers significant performance advantages, with data processing capabilities of up to 1300 DMips, and 8 megabytes of flash and 640 kbytes of SRAM, meeting the requirements of high-speed, stable data processing under demanding conditions. For the current functional safety ISO26262 standard, Aurix can help customers achieve the highest level of ASIL-D in system applications. At the same time, Aurix has a wealth of peripherals to meet the growing demand for in-vehicle network architecture, from 512kB to 8MB flash range, from TQFP80 to LFBGA516 various packages, a comprehensive product family can be compatible with developers of different applications and development compatible Sex.
It is reported that the Quartet cooperation project is mainly for Shanghai Dajun Power Control Technology Co., Ltd. to explore and develop motor controller basic software and some application layer software that meet AUTOSAR 4.0.3 specifications. The Chinese-German College of Tongji University designed the hardware circuit of the motor control board based on Infineon's Aurix series TC275 microcontroller and TLF35584 chip. Based on the concept of Victor's multi-core OS, multiple tasks, CAT1 and CAT2 interrupts were planned and allocated to In the multiple cores of the TC275, to ensure reliable data exchange between multiple cores, the advantages of the TC275 multi-core CPU are fully utilized to make the motor control safer and more stable.
Secondly, the Chinese University of Technology in Tongji University designed the RTE software architecture using the DaVinci Developer tool from Victor, including all application-layer SWC frameworks and the included Runnables and interface variables. Using MATLAB/Simulink tool to develop a full-featured SWC model, including various fault diagnosis modules and motor control algorithm modules. After verification of the MIL/SIL/PIL test, the Simulink model was converted to SWC source code using code auto-generation techniques. At the same time, the Infrared MCAL configuration tool and Victor DaVinci Configurator were used to rationally configure the MCAL, ECU abstraction layer, service layer, etc., and developed basic software (BSW) that complies with AUTOSAR specifications. According to different application requirements, the BSW module can be flexibly increased or decreased. Through the standardization of BSW, the hardware can be abstracted from the software, which improves the reusability of the application layer software and greatly improves the development efficiency of the application software engineer.
Finally, integrate the basic software and application layer software to achieve a stable and reliable motor torque control.
In addition, Shanghai Dajun Power Control Technology Co., Ltd. and Tongji University have also won the national key research and development program "motor drive controller power density multiplication technology (major common key technology class)" funding, will be further developed with Infineon, Victor In-depth cooperation, based on the current Infineon Aurix TC275 hardware platform and Victor AUTOSAR 4.0.3 software platform, the introduction of the ISO26262 specification design process, targeting the functional safety goals put forward by automotive manufacturers, in the design of the system, hardware and software It added functional safety mechanisms and developed motor controllers that meet the ASIL-C level and plans to achieve mass production of motor controllers in 2019.
