The core power unit of an electric vehicle is the motor and control system. The power performance, energy consumption level, and operational reliability of the entire vehicle are directly determined by the integrated design and integration technology. This paper focuses on the research strategies of integrated design and integration technology for the motor and control system, and combines the power requirements of pure electric vehicles to complete multiple rounds of optimization of the integrated structure design, key component matching, and integration scheme. It proposes a scientific and feasible research and development plan to solve the pain points of the traditional separate architecture, such as bulky volume, high energy loss, and poor software-hardware coordination matching. A pure electric passenger car model was selected as the test carrier, and an integrated simulation test platform for motor and control system was built. The core simulation parameters of this platform include: rated power of the motor 120 kW, peak speed 12000 r/min, and the test environment temperature maintained at 25 ℃±2 ℃. The test data were simultaneously derived from the verification results of bench real vehicle testing and MATLAB/Simulink simulation. The test results show that the optimized integrated architecture can reduce the system volume by 15% to 20%, lower the vehicle energy consumption by 8% to 12%, and improve the collaborative working efficiency of the motor and motor controller by 10% to 15%.
