“…When parametric design first appeared and started to be used in architectural design industry, some inspired architects tried to create new design methods, aiming at meet the more and more complicated requirements for architectural designs in modern society. This trend gradually developed into a new architectural design style, which is now known as parametricism [5].…”

As a widely applied method in many fields, parametric design is now finally exerting influences on architectural industry with the rapid development of Internet technology. For this reason, parametric architectural design is studied in this research based on optimization method. First, parametric design and optimization algorithm are introduced; then, the process of modeling and optimization procedures is discussed; at last, the parametric optimization design is applied to solve the complex architectural design problems. Parametric method will thoroughly affect architectural industry. Therefore, architectural designs should be based on optimization algorithm using parametric design to improve the progress and quality of architectural design.

“…Architectural designs of previous eras can hardly meet the requirements of a new era as time goes by. The emergence of parametric design is actually a call for new design styles when the architectural design system of previous eras falls into a decline [5]. From the technical methods adopted in parametric architectural designs we can see the reflection of the new era.…”

“…In order to take advantage of the PHEV for fuel economy, automatic transmission (AT), automatic mechanical transmission (AMT), and dual clutch transmission (DCT) technologies have been applied to hybrid transmission systems, and most of them usually have 6‐8 gear ratios, which not only significantly restrict the improvement of fuel economy but also create shock during gear shift. In contrast to them, an infinite number of gear ratios can be provided by CVT within the limits of the mechanism, so there is a chance to achieve the best match between the working points of the engine and the motor . As a result, the fuel economy and comfort of the vehicle can be improved.…”

Summary In order to improve the fuel economy of hybrid electric vehicles, a novel plug‐in power‐reflux hybrid electric vehicle powertrain equipped with an electromechanical control continuously variable transmission (EMCVT) is proposed in this study. The proposed structure, which combines the dynamic property of the planetary mechanism and regulating characteristics of the continuous speed ratio with EMCVT, can transmit power in two modes, namely power‐reflux mode and pure‐CVT mode, thus realizing the multistage design of the overall transmission system. Hence, it demonstrates a wider speed ratio variation range and higher transmission efficiency than the “Pathfinder‐like” parallel configuration with traditional electro‐hydraulic CVT (EHCVT). To take full advantage of its potential for fuel economy, the highest transmission efficiency of the system is taken as the optimization objective for the target speed ratio of the system. The optimization results are incorporated in the control strategy based on Pontryagin's minimum principle to simulate fuel consumption under the new European driving cycle (NEDC), highway fuel economy test (HWFET), and urban dynamometer driving schedule (UDDS). Compared with the simulation of the “THS II‐like” configuration with similar vehicular parameters, the results show that the novel configuration has better fuel economy.
