Summary:

The automatic mechanical transmission (AMT) was designed by automobile manufacturers to provide a better driving experience, especially in cities where congestion frequently causes stop-and-go traffic patterns. It uses electronic sensors, processors, hydraulic or pneumatic actuators execute clutch actuation and gear shifts on the command of the driver. Such systems coupled with various physical domains have great influence on the dynamic behavior of the vehicle, such as shift quality, driveability, acceleration, et cetera This paper presents a detailed AMT model composed of various components from multi-domains like mechanical systems (clutch, gear pair, synchronizer, et cetera), pneumatic actuator systems (clutch actuation system, gear select actuation system, gear shift actuation system, et cetera). Various components and subsystem models, such as the vehicle, engine, AMT, wheels, et cetera, are integrated into an overall vehicle system model according to the transmission power flow and control logic. The model is implemented using the Modelica programming language in an object-oriented environment. The simulation of the AMT model was carried out for the analysis of vehicle overall performance
