Integrated Control Optimization of Dual Clutch Transmission Gears for Electric Vehicles

The control of the transmission shift in vehicles is significant for driving comfort. In order to analyze the shift quality effectively, the transmission system dynamic parameters are taken as the input variables, and the comprehensive evaluation index of the weighted form of the jerk and friction work is introduced to determine the optimization objective function. The optimization problem of dynamic parameter input variables is transformed into the parameter optimization problem that particle swarm can be processed by Fourier transform. So the optimal torque trajectory of the motor and clutch during the upshift is obtained. (paper)
