Abstract:

A co-simulation model of whole-vehicle dynamics was established based on MATLAB/ Simulink and AMESim. Also a precise dynamics model of torque converter, locking clutch and torsional coupling power transmission was developed. The Proportional-Integral-Derivative (PID) controller of the lock-up clutch was designed using torque converter pump wheel and turbine speed as slip control parameters. The MATLAB Optimization Toolbox was used to optimize the slip speed based on the evaluation of the level of torque fluctuations and transmission efficiency. Simulation results show that, when the vehicle is started with small throttle, the lock-up and slip control should not be used due to unstable condition of the engine;when the vehicle is started with medium throttle, large throttle and full throttle opening, the engine works in its best working condition because of the involvement of the lock-up clutch that actively intervenes the engine operating point. The slip and lock-up control of the lock-up clutch achieves a better allocation of power transmission and balances the relationship between the energy loss and NVH.

Key words: vehicle engineering, torque converter, launching condition, genetic algorithm, lock-up and slip
