| Abstract: | The variable magneto-resistance excited rotation speed sensor in automobile ABS and the signal processing was studied in this paper.Based on it,the requirement for the circuit used to process the wheel rotation speed sensor's signal was put forward and the circuit consisting of low-pass filter plus lagging comparator was designed.The simulation results under the Matlab/Simulink environment and experiments show that the circuit is reliable and could minimize the effect of electromagnetic interference,and it can satisfy the requirement of ABS. |
