STUDY ON THE CALCULATION AND SIMULATION OF POWER SOURCE SWITCHING MODES ON A GASOLINE – ELECTRIC HYBRID PASSENGER CAR, TOYOTA COROLLA ALTIS HYBRID 1.8HEV

Abstract

In this article, the authors present the results of a simulation study of power conversion modules on a Toyota Corolla Altis 1.8HEV hybrid vehicle, including a DC-DC converter that steps up the battery voltage from 201.6V to 650V, and an inverter that converts the DC source voltage U = 650V to a three-phase AC supply for the permanent magnet synchronous motor. Using numerical simulation software Matlab - Simulink, the study allows for the calculation and control of the speed and torque on the electric motor shaft. The research results and simulations help learners gain a more comprehensive understanding and more accurate assessment of the speed control methods used in hybrid vehicles (gasoline-electric hybrid) as well as electric cars, thereby fostering better scientific thinking in technical consulting, maintenance, and repair of hybrid and electric vehicles. This also provides a foundation for supporting teaching, learning, scientific research, and improving the quality of training for staff and lecturers in the automotive engineering technology field at the University of Technology.
