Exploring the a343e Automatic Transmission Operation with Matlab/Simulink

Abstract

In this article, a survey was conducted on the A343E Toyota Fortuner 2015 automatic transmission using Matlab/Simulink software with Simscape blocks to quickly create blocks with characteristics of the systems on the vehicle. The article develops a process for shifting the automatic transmission based on signals from the vehicle speed and throttle position that are appropriate for the engine characteristics, vehicle characteristics, and existing gear ratios. The purpose of this article was to investigate and analyze vehicle dynamics based on the theory of automobiles. The simulation results show that the operation of the automatic transmission will allow the vehicle to reach a maximum speed of 189.5 km/h under condition 4 and maximum throttle opening, and the vehicle's ability to accelerate from 0 km/h to 100 km/h in 14.68 seconds.
