Abstract:
Automotive automatic transmission control strategy was divided into upper and bottom layer control parts, and its layered coordinated control was adopted. The bottom layer was the basic shift controls of optimal power and optimal economy, the upper decision-making layer was used to give the dominant analysis and priority settings for the identifiable informations of driving intention, vehicle condition and road environment, vechicle control objective with optimal performance at present state was given, and the amendment and adjustment of basic shift control strategy for bottom layer were made. Analysis result indicates that compared with independent control, the shift times of vehicles based on layered coordinated control strategy in climbing ramp and bend conditions reduce by 4 times and 2 times respectively, shift reduces promptly when gearbox oil temperature rises, and shift is higher when vehicle starts on low-adhesion coefficient road. The layered coordinated control strategy can reduce shift jump frequency and the wear and tear of shifting part, improve vehicle passing ability, ride comfort and safety. 3 tabs, 17 figs, 14 refs.
