AI Technical Summary
In existing technologies, the noise problem of rear wiper motors is difficult to solve effectively, especially under intelligent control, the NVH verification and debugging process of the motor is cumbersome and takes up a long development cycle.
By establishing a test bench to obtain noise levels and brush stroke counts, fitting a noise level-brushing stroke count curve, comparing it with a standard curve, identifying out-of-tolerance areas, and performing low-voltage start-up or delayed commutation processing based on the type of out-of-tolerance area, adjusting motor parameters to meet motor evaluation requirements.
The system automates the calibration of rear wiper motor noise, improving calibration efficiency and effectively reducing motor startup and commutation impact noise, thus meeting subjective evaluation requirements.
