Matematički model automatske transmisije u putničkim motornim vozilima

Abstract

Automatic transmission is.one of the most complex subsystems of motor vehicle. It consists of three divisions i.e. electronic control unit, hydraulic control unit and mechanical components. The main objective of application of automatic transmission in passenger cars is to reduce strokes during a gearshift i.e. to achieve as much quality in gear shifting as it is possible. In most cases, experimental methods for investigation of quality and parameters of gearshift, as well as development of control algorithms are used. However, experiments demand great material means and time, so it is convenient to develop a mathematical model that can simulate the whole transmission, save time and money and confirm experimental results. A dynamic model of automatic transmission system having the objective to simulate the real operating conditions of all system components is presented in this paper.
