| Abstract: | The essential theory of the mechanical characteristic test of the wiper motor without torque and speed sensors is discussed in this paper. The relationship between wavelet ridge and instantaneous frequency is analyzed and a new method of the mechanical characteristic test of the wiper motor based on wavelet ridge algorithm is proposed. Experimental results show that the mechanical characteristic curve of the wiper motor can be rapidly and exactly acquired based on wavelet ridge. |
