Development of automobile hybrid powertrain rational control strategy during driving cycle]
EDN: KEYQKI
Abstract
Introduction (problem statement and relevance). Considering the significant distances between settlements and underdeveloped infrastructure for widespread exploitation of pure electric vehicles, the application of hybrid vehicles (HVs) in the Russian Federation is considered justified and allows using them flexibly as an alternative to the vehicles with conventional powertrains and pure electric vehicles. The task of saving energy recourses, especially non-renewable ones, provided that the necessary transport operations are completed, is relevant for vehicles with all types of powertrains.
The purpose of the study is to develop a method for finding a rational control strategy for a parallel and serial-parallel types of hybrid powertrains (HP) in the specified driving cycle: an energy efficiency criterion, approach to selection of variable parameters, and optimization sequence have been offered. Methodology and research methods. Numerical methods of research have been applied. The driving process of the Toyota Prius ZVW52 vehicle under WLTC driving cycle conditions is reviewed as an example, for which the hybrid powertrain (HP) characteristics mathematical models were developed by calculation.
The results and scientific novelty are that the proposed method allows reducing the computational complexity of the objective of HV units rational control within the assigned driving cycle in relation to the known approaches by combining the same-type driving modes into groups, excluding non-implementable and non-rational operating points from the possible system states along with subsequent application of multi-parametric optimization to the remaining number of states.
Practical significance. The method developed can be applied to improve the parallel and serial-parallel type HV control algorithms in order to achieve the maximum joint efficiency of the internal combustion engine and electric drive under driving cycles conditions as well as under real driving conditions.
