Automatic Transmission Simulation Model in the Test Set

Abstract

The paper recommended sequence of possible safe combinations of virtual and real nodes for testing automatic transmissions at different stages. It describes a mathematical model for automatic hydromechanical transmission designed to work together with a single programmed controller. Examples of the simulation are shown. The main components of the complex are designed to operate with MatLab/Simulink. Loading modes of transmission and the most mobile machines combines the task of technological and transport resistances backgrounds. The operating cycle consists of moving off, acceleration, gear, performance of technological and transport operations. The virtual model is used for testing aims for programmed controllers to check them and to improve gear - shifting algorithm.
