To solve the problems of poor smoothness and big frictional work in start-up of automated mechanical transmission with wet clutch. The start-up fuzzy control strategies is proposed. The precise control of clutch pressure is obtained by using optimization of fuzzy control parameter based on ant colony algorithm. The simulation and experiment results showed that the control strategy reduces the driveline...
The dynamics model of the AMT system was established. Optimal shifting schedule is proposed by dynamic programming algorithm, which use speed and power requirements as control parameters, and the minimum fuel consumption as the optimization goal. The results showed that the optimal shifting schedule could reduce the shift frequency and improve the fuel economy on the premise of no loss of power.
A pressure control method of shift was proposed for the dry dual clutch transmission. The pressure control model of dry dual clucth was established, and shift strategy in different stages of shift process was proposed. The clutch target torque and cylinder target pressure in different stages of shift process were obtained based on shift jerk, and the pressure control of dry dual clutch was realized...
To solve the problems existed in vehicle starting with wet dual clutch transmission, the starting strategy was developed on the basis of clutch evaluation and dynamics analysis about transmission. The wet clutch target pressure of starting phases is determined by fuzzy control method. Parameter adaptive PID controller was used to realize clutch pressure's accurate control. In order to verify the validity...
The performance of electric vehicle depends on power battery performance to a great extent. Accurate assessment of the power battery status is the premise of power battery playing its best performance under the existing technology conditions. The order 2 RC battery model is verified by comparing simulation result with experiment data. A standard identification form which is suitable for gradient adjustment...
