In this paper, we determine the smoothing scale by diffusion balance with analyzing the signal and the noise energy variation in anisotropic diffusion smoothing processing.
这里通过各向异性扩散过程中信号与噪声能量的变化，利用扩散平衡来确定平滑的时间尺度。

It shows signal harmonics is obviously weakened by the smoothing action in the setting process and there is a best conversion frequency to minimize harmonic distortion.
The real vehicle tests indicate that the filtered wheel speed signal has small time delay and quick response with relatively ideal smoothing effects and can be used for direct speed estimation.
