Simulation Analysis on Control Strategy of Launch with Two Clutches for Dry DCT

Abstract:

Based on the control principle with a constant engine speed, the coordination control process between engine and clutches during launching was analyzed. The maximum engaging speed of clutches and the maximum change rate of throttle were calculated with the maximum degree of jerk as the limited condition, and the control strategy of launch with two clutches was established. Genetic algorithm was used to optimize the distribution coefficient of torque between two clutches. The simulation results show that the control strategy of launch with two clutches using two clutches work together and the reasonable distribution of torque could be advantageous for clutches enduring life.
