Background Introduction
As a key technology direction prioritized by the state, China has made rapid advancements in the field of new energy vehicles, with the market scale continuously expanding. New energy vehicles replace traditional engines with electric motors as the core of vehicle power output, while the Motor Control Unit (MCU), as one of the core components of the “three electrics,” plays a crucial role in connecting the motor and the vehicle. The main function of the MCU is to monitor the real-time status of the motor and convert the direct current provided by the power battery into three-phase alternating current according to the demands transmitted by the vehicle controller, thereby precisely controlling the output speed and torque of the motor.
When the reliability of the MCU controller software is poor, it can directly lead to the motor not functioning properly, affecting the realization of vehicle functions, further reducing the vehicle’s power performance, economic performance, and comfort, and may even trigger uncontrollable safety incidents. Therefore, ensuring the high reliability of MCU controller software has become a focus for major OEMs and suppliers. HiL testing, as a key link in the “V”-shaped development process, significantly enhances software reliability when conducted after software development, while also offering advantages such as comprehensiveness, safety, efficiency, and low cost.
