Abstract
Electric motors and Internal Combustion Engine test benches allow for testing, under various conditions, the behavior of the Electric Vehicles and they are essential in the automotive field development. In this paper, we introduce the state-of-art of the control algorithms and their validation over different test runs, on the standard driving cycles. Ad-hoc simulations and test benches designed for the issue offer a significant opportunity to reduce costs. The modelling of automotive systems is a non-trivial problem due to the non-linearities. The paper presents a linearized solution and an adaptive control scheme to improve model performances starting from real data, and also discusses the behavior of the proposed system and the control law reporting emissions of the considered virtual vehicle when compared with the target emission regulations.
Highlights
In recent years, in the automotive industry, the electric motors market has grown
Different types of classification could be done related to the new vehicles that are based on the chosen motor, the design of their permanent magnets, the energy system and source, and the configuration of the power transmission inside the Electric Vehicles in general (EV) [6,7]
The vehicle architectures vary every day, and the state of art is fusing on power coming from the classic Internal Combustion Engine (ICE) with the innovative electric thrust
Summary
In the automotive industry, the electric motors market has grown. The attention about the environment and the renewable energy has led to the electrification of road transport [1,2,3].Nowadays, one of the challenges is the reduction of carbon dioxide emissions [4]. Automated controls are integrated to operate electric motors providing the versatility of automatic functions [5]. Different types of classification could be done related to the new vehicles that are based on the chosen motor, the design of their permanent magnets, the energy system and source, and the configuration of the power transmission inside the Electric Vehicles in general (EV) [6,7]. This paper presents the configuration of a mild hybrid electric vehicles (MHEVs). MHEVs are vehicles where propulsion energy is available from more than one type of energy stores, sources, or converters, and at least one of them can deliver electrical energy. The significant features on EVs are the electrical power available, the fuel consumption, the functions performed, and the battery voltage. At the end of the paper, the results will show the difference about fuel consumption between the standard driving cycles
