The Research on Shift Rule of Double Clutch Transmission

Abstract:

Based on the dual clutch automatic transmission, the shift rule is studied. MTTLAB is used to establish the engine model, the transmission model and the vehicle dynamics model respectively. The input parameters are numerically analyed to analye the shift rules of the vehicle, including the best dynamic shift law and the best fuel economy shift law, the combination of shift law. According to the simulation results, we analysis three indicators which include shift speed and quality and fuel consumption.The acceleration performance of the vehicle is better than that of the economic shift rule when the dynamic shift rule is adopted. When the combined shift rule is adopted, the acceleration performance is changed from the slow to the fast. Economic shift law behave the minimum fuel consumption and the best economic performance, combined shift of the economy followed by the economic shift law, the dynamic law is the worst performance of the economy. The combined shift rule is suitable for vehicles that do not have special power requirements and fuel economy requirements for vehicles or vehicles that travel for a long period of time.
