Xin1 Powertrain Domain Multi-in-One Controller

Against the development trend of high intelligence and high electrification in the automotive industry, an increasing number of electronic modules are equipped in vehicles. Accordingly, the optimization of vehicle electrical architecture has become a key approach for major OEMs in recent years to cut costs and improve performance. Amid the general trend of automotive electronic architecture evolving toward system integration, the functional integration of controllers within a single functional domain has emerged as an important development direction.

The Xin1 domain controller realizes in-depth integration and optimization of the motor controller, battery management unit and vehicle control unit within the traditional powertrain domain. Adopting the latest generation of SiC technology for the motor controller part, it greatly enhances controller efficiency and achieves high power density. Meanwhile, it provides abundant low-side control, analog acquisition, IO output and other functions required by the battery management unit and vehicle control unit.

It adopts STMicroelectronics’ 32-bit multi-core chip SPC58NN as the main control chip to maximize the integration of chip resources and optimize power distribution. On the premise of compact structure and high reuse rate of circuits and chips, the design reliability is improved to the greatest extent. In addition, this system solution features scalable functional safety performance. Devices such as the driver chip L9502 support ASIL-D functional safety level. While keeping the overall solution architecture unchanged, it can further meet functional safety requirements by adding relevant software and hardware functional safety designs in subsequent iterations.
