The study focuses on the control method optimization for the Dual Clutch Transmission upshift process during the torque phase. The upshift process and two power flow paths are analyzed in detail. According to the analysis results, if two clutches slip together during the DCT upshift process, either torque hole or power circulation generates. To avoid these two conditions, the torque relationship between two clutches is optimized to enable the off-going clutch to disengage without slippage. The Matlab/Simulink platform is used to establish the DCT dynamic model. The obtained simulation results illustrate that, compared with the control methods based on two clutches slippage, the optimized one can not only avoid torque hole and power circulation, but achieve the highest system efficiency during the torque phase, which means the least friction work and the extension of clutch life.
