MBD-based Modeling and Dynamic Characteristic Analysis of Electric Vehicle Key Components and Hybrid Control Unit

Abstract

In general, electric vehicles have significantly different structures compared to vehicles running on internal combustion engines owing to their use of electric motors as the source of power and batteries as energy-storage devices. Electric vehicles also demonstrate different driving performance and dynamic characteristics, as they are capable of recovering some of the energy wasted in the form frictional heat at the brake through use of regenerative braking during deceleration. The proposed study discusses a mathematical model constructed by identifying characteristics of certain key components and the hybrid control unit (HCU) of an electric vehicle. Corresponding correlations among these components were analyzed. In addition, a dynamic model of the electric vehicle was designed using the model-based design approach in accordance with the standard V-Model development process ISO 26262-an international standard for automotive safety. All models discussed herein were developed using the MATLAB/SIMULINK package, and dynamic characteristics of the vehicle were analyzed through simulations.

Research on the intelligent generation method of MBD model 3D marking using predefined features

“…Boeing, the leaders of global aerospace industry, applies MBD to aircraft life-cycle design and manufacture and the development of related standards (Bhanumathi and Haridas, 2013). General Electric, the world’s largest multinational provider of technology and services (Yoon et al, 2018), proposes a Brilliant Factory plan in 2014, it applies MBD to realize 3D manufacturing. In China, high-speed train enterprises are also fully implementing 3D digital design of MBD.…”
