Abstract:

Article Preview

Aimed at clutch magnetoelectric tachometric transducer, rotational speed signal processing had achieved good results in hardware circuit and software algorithm two aspects. Firstly in hardware aspect RC Low-Pass Filter’s parameters are optimized by frequency-domain analysis of actual rotational speed signal according to vehicle travel features. As a result, useful information is reserved and high-frequency noise is shielded effectively. Secondly in software aspect, through analyzing the clutch control system’s characteristics and speed data’s structure, explicit Euler formula is adopted to predict the data’s structure. Maximum likelihood estimate of Mathematical Statistic Analysis is used to raise the data’s utilization and enhance the data’s robustness in order to provide the effective and stable parameters for clutch control.
