Study on fuzzy gearshift tactics in automatic gearshift control system of technical vehicles

In this paper according to the energy-saving gearshift law of the hydraulic mechanical transmission, adopting fuzzy control technology, establish the self-correction fuzzy gearshift tactics. This fuzzy gearshift tactics is consisting of the basic fuzzy gearshift tactics and fuzzy correction module. The test results showed that the energy-saving gearshift law tally with the request of the vehicle gearshift. The self-correction fuzzy gearshift tactics can decrease the gear times, enhance the economy of the fuel and the efficiency, and improve the gear quality.
