HIRAIN Electric Drive All-in-One XCU

In the current automotive industry, intelligent and electric technologies have become an irreversible trend. Faced with the complexity and cost issues caused by decentralized control systems in traditional vehicle architectures, the industry is gradually shifting toward integrated multi-functional controllers. Against this backdrop, Jingwei HiRain has introduced its XCU solution, which integrates various functions—such as vehicle control, motor control, power management, body control, and intelligent connectivity—into a single, efficient hardware platform. This significantly improves system response speed and reliability. Recently, this solution has been applied to Geely’s latest intelligent electric vehicle model, the Geely Xingyuan, providing strong technical support for its mass production.

As a leading automotive electronic systems technology service provider in China, Jingwei HiRain has been deeply involved in the field of multi-functional controllers for a long time. Beyond the functions integrated in the aforementioned XCU solution, the multi-functional controller also incorporates traditional high-power components such as the Motor Controller (MCU), Onboard Charger (OBC), DC-DC Converter (DCDC), and High Voltage Distribution Unit (PDU), further enhancing the power density of the entire controller. Thanks to its efficient system integration, it reduces the number of hardware components and connection complexity, which in turn decreases the controller’s size, increases vehicle space efficiency, reduces vehicle weight, and improves economic efficiency. Additionally, the modular design allows for flexible functionality expansion, facilitating future product upgrades and optimizations. With the accelerated trend towards intelligent and electric vehicles, multi-functional electric drive controllers will become one of the core technologies of future electric vehicles, driving the automotive industry towards higher efficiency and smarter development.

High integration undoubtedly raises stricter standards for software and hardware integration technologies. Jingwei HiRain’s engineers, targeting industry benchmarks, have continuously focused on R&D, dedicating extensive efforts to addressing challenges in areas such as motor efficiency enhancement, EMC, NVH, and thermodynamics. In the software development process, the engineering team independently developed a series of configuration and testing tools for application-layer models and low-level code, such as HiToA, HiToB, HiToC, and HiToT. These tools help engineers accelerate software development and iteration by:

•    Enabling the rapid establishment of model architecture and automatic model generation to improve efficiency
•    Providing quick adaptation solutions for commonly used project modules based on the AUTOSAR EAS 4.2.2 protocol stack
•    Conducting efficient checks on software and its executable programs to ensure quality
•    Supporting the integrated use of various testing tools to comprehensively verify software performance
