Analysis of Dynamic Characteristics of Clutch-to-Clutch Shifting Control of an Automatic Transmission
The fact that requirements for shift quality in automatic transmissions have been increasing rapidly necessitates the establishment of a suitable shifting control strategy in order to facilitate smoothness of different processes. For this very purpose, this paper introduces a simulation model of an 8-speed automatic transmission for front-drive vehicles with respect to detailed shifting strateg...
متن کاملClutch-to-clutch Shift Control of an Automatic Transmission with Proportional Pressure Control Valves
For a new kind of automatic transmissions using proportional pressure valves to control the clutches directly, a two-degree-of-freedom controller is designed for clutch slip control during the inertia phase of the shift process. The controller is designed based on a low order linear model which is derived from dynamics of the proportional pressure control valve and the vehicle drive line. The f...
متن کاملShift Control System of Heavy-duty Vehicle Automatic Transmission
Heavy-duty vehicle hydrodynamic mechanical automatic transmission shifting operation system was designed, mathematical model of its simplified hydraulic system was established and simulation model of shifting operation system was established with AMESim, the simulation experiment was carried out, then oil pressure curves of each clutch hydraulic cylinder were obtained when giving forward gear o...
متن کاملControl of Heavy-Duty Trucks: Environmental and Fuel Economy Considerations
In this project we investigate the effect of heavy-duty trucks, equipped with different Adaptive Cruise Control (ACC) systems, operating in mixed traffic with manually driven passenger vehicles, on the environment and traffic flow characteristics. The sluggish dynamics of trucks whether manual or ACC that is due to their limited acceleration capabilities filters speed disturbances caused by lea...
متن کاملShifting Control and Analysis of Dual Clutch Transmission of Automobile
According to the DCT structure and principle, the dynamic shifting process of DCT has been analyzed, and the engine and clutch model have been established. The driver intention has been analyzed and distinguished through the fuzzy control theory, on this basis, gear shift rule has been formulated based on driver intention,separately from the power performance and economy performance. Clutch and...
