Abstract:

The vehicle dynamics model are important tools for research and development in automotive Industry . In today’s fast paced industry, the use of software-based simulation plays a vital role in testing and verification of products. The vehicle longitudinal dynamics considers the behavior of different forces acting on the vehicle during its longitudinal motion. The resistance forces in turn may affect the performance of the vehicle powertrain , pushing the propulsion system to provide more better performance to overcome the resistance. This leads to lowering of efficiency or increase in power loss. To observe the vehicle behavior in real life , it may certainly require costly experimentation or simulations , on the other hand software-based approach can lead to a less time-consuming situation. The Aim of this thesis is to provide a model that is like a vehicle with an electric powertrain and analyzing the efficiency and losses by experimental techniques followed by using software-based approach.Hence, a software package or toolbox that can perform different tasks related to vehicle dynamics and performance shall be presented. The Thesis was carried out using Octave software that features a high-level programming language, primarily intended for numerical computations. The Results obtained from the simulation of the software are in line with real world behavior of a vehicle with electric powertrain. However , it is certain that such models are used for providing a bottom line and a perspective in real driving conditions.
