Abstract

The invention discloses a control method of a wet type dual-clutch transmission. The method comprises the steps of receiving an opening signal of an economy switch; judging whether the current transmission state is allowed to enter the economic mode or not; if yes, sending a first control signal to an engine controller so as to enable an engine to be in the economic mode; switching a current gear shifting figure of the transmission to an economic gear shifting figure; according to the control method of the wet type dual-clutch transmission, after the engine enters in the economic mode, the current gear shifting figure of the transmission is switched into the economic gear shifting figure, and therefore the transmission enters in the economic mode after the engine enters in the economic mode, the transmission and the engine achieve economic mode cooperation, and the fuel economy is further improved.

Description

technical field [0001] The invention relates to the control technology of the automobile gearbox, in particular to a control method of the wet dual-clutch gearbox. Background technique [0002] A typical wet dual-clutch automatic transmission consists of two coaxial nested or parallel arranged clutches, two coaxial and inner and outer nested input shafts, two parallel output shafts, and multiple clutches arranged on the output shafts. Synchronizer unit, multiple shift forks and a differential. The odd and even gear input gears of the transmission are respectively arranged on the two input shafts. Through the switching of the two clutches and the action of different synchronizers, the torque conversion and output are realized through different output shafts. The transmission power flow is: engine output torque - transmission input Shaft-dual clutch-transmission output shaft-wheel, during the entire power flow transmission process, the dual clutch is combined and released und...
