The A-PMP optimizes gearshift commands and torque distribution for overall energy efficiency. As a practical numerical solution in PMP, the proposed methodology utilizes a piecewise linear approximation of the engine fuel rate and state of charge (SOC) derivative by considering drivability and fuel economy simultaneously. Moreover, battery aging is explicitly studied by introducing a control-oriented model, which aims to investigate the effect of battery aging on the optimization performance in the development of the HEVs. An approximate energy management strategy with piecewise linear models is then formulated by the A-PMP, which targets a better performance for the Hamiltonian optimization. The gearshift map is extracted from the optimal results in the standard PMP to hinder frequent gearshift by considering both drivability and fuel economy. Utilizing an approximated Hamilton function, the torque distribution, gearshift command, and the battery aging degradation are jointly optimized under a unified framework. Simulations are performed for dynamic programming (DP), PMP, and A-PMP to validate the effectiveness of the proposed approach. The results indicate that the proposed methodology achieves a close fuel economy compared with the DP-based optimal solution. Moreover, it improves the computation efficiency by 50% and energy saving by 3.5%, compared with the PMP, while ensuring good drivability and fuel efficiency.<br /> <br /> Document type: Article<br /> <br /> == Full document ==<br /> &lt;pdf&gt;Media:Draft_Content_920187664-beopen1333-4277-document.pdf&lt;/pdf&gt;<br /> <br /> <br /> == Original document ==<br /> <br /> The different versions of the original document can be found in:<br /> <br /> * [https://www.mdpi.com/2032-6653/11/4/65 https://www.mdpi.com/2032-6653/11/4/65],<br /> : [https://doaj.org/toc/2032-6653 https://doaj.org/toc/2032-6653]<br /> <br /> * [https://www.mdpi.com/2032-6653/11/4/65 https://www.mdpi.com/2032-6653/11/4/65],<br /> : [https://www.mdpi.com/2032-6653/11/4/65/pdf https://www.mdpi.com/2032-6653/11/4/65/pdf],<br /> : [https://academic.microsoft.com/#/detail/3092541750 https://academic.microsoft.com/#/detail/3092541750]<br /> <br /> * [https://www.mdpi.com/2032-6653/11/4/65/pdf https://www.mdpi.com/2032-6653/11/4/65/pdf],<br /> : [http://dx.doi.org/10.3390/wevj11040065 http://dx.doi.org/10.3390/wevj11040065] under the license https://creativecommons.org/licenses/by/4.0/</div>
