A REVIEW ON AUTOMATIC MANUAL TRANSMISSION

Abstract

As the name suggests, Automatic Manual Transmission is a manual transmission with clutch and gear actuation performed using either electromechanical or hydraulic actuators. In order to determine the actuation of actuators, the entire AMT system has a control strategy. Major research efforts have been conducted over the last two decades to improve vehicle transmissions that reduce the energy consumption of a car. This initiative has been a direct consequence of the increasing environmental concern placed on current vehicle manufacturers by the Directives on lower exhaust emissions and improved vehicle performance. Consumers often demand a reasonable price to achieve the same level of efficiency, comfort and ease of use as in regular cars. In order to create a competitive solution, the efficiency, comfort and price of existing vehicles on the market must all be comparable. The best competitive solution to address the problem of performance, comfort, cost, efficiency is automated manual transmission (AMT). The main objective of this paper is to review the different research work conducted in terms of design and control strategy on the AMT system.
