Vehicle Dynamics Effect on Energy Efficiency in Hybrid Electric Vehicles

The present paper introduces an analysis method that quantifies through simulation the impact of vehicle dynamics on the energy efficiency. The research is based on Matlab modeling and closed loop approach. The study considers a set of critical parameters that influence the energy efficiency. The added value is given by the increased energy efficiency as a result of the implementation of the proposed principles. A new user interface design is proposed as well. This design represents the concept phase being situated on the beginning of the development "V" cycle. It is a system design solution that needs to be followed by SW design, SW implementation and corresponding validation and verification activities. A set of 216 case studies are proposed for a good performance assessment and the efficiency of the analysis method is proven through a series of simulation results. The motivation of the research is given by the fact that the battery efficiency is one of the most critical concerns in the actual "Electric" automotive market. Implementing the proposed system level solution, in terms of energy control, results in better energy efficiency and better costs. The advantage of this method is that the energy consumption can be managed automatically by the electronics and software so that the best possible energy efficiency can be reached. The current proposal comes to support the autonomous driving principles. The results contribute to the practical need of developing new control systems, more efficient from the energy management perspective, with a better cost and higher quality standards.
