Development Trends of Transmissions for Hybrid Electric Vehicles Using an Optimized Energy Management Strategy Tianze Shi, Fuquan Zhao, Han Hao, Zongwei Liu |
||
| Energy conservation and emission reduction have become increasingly significant for automobiles due to the severity of the current energy situation. Hybrid electric vehicles (HEV) technology is one of the most promising solutions. This study investigated the total efficiency of a HEV powertrain. To improve the total efficiency, the engine should be regulated to work at its highest efficiency and drive the wheels directly as much as possible. To accomplish this, we developed an energy management strategy based on the direct drive area (DDA) of the engine’s efficiency map. Several typical HEV models were built to compare the fuel consumption using DDA and rule-based strategies. Furthermore, the function of the HEV transmission system with DDA was considered. The transmission in a HEV should regulate the engine to work at its highest efficiency area as much as possible, which is rather different than the regulation in an internal combustion engine vehicle. The functional change may lead to transmission systems with fewer gears but optimal gear ratios. If this trend is realized, the manufacturing cost of HEVs could be largely reduced. | |||

Engine-map-based Predictive Fuel-efficient Control Strategies for a Group of Connected Vehicles Lihong Qiu, Lijun Qian, Zoleikha Abdollahi, Zhouwei Kong, Pierluigi Pisu |
||
| An engine-map-based predictive fuel-efficient control strategy for a group of connected vehicles is presented. A decentralized model predictive control framework is formulated to predict the optimal velocity profile that compromises fuel economy and mobility while guaranteeing the safety of each vehicle. In the model predictive control framework, an engine-map-based fuel consumption model is established by implementing a backward conventional vehicle model in the cost function. Moreover, the cost function is normalized by dividing each term by its reference value. An extra cost is added to the safety term when the distance between adjacent vehicles drops to a critical value to guarantee vehicle safety, while another extra cost is considered for the velocity tracking term to prevent the violation of traffic rules. The results of simulation show the effectiveness of the proposed control method. | |||

CO2 Reduction Request and Future High-Efficiency Zero-Emission Argon Power Cycle Engine Liguang Li, Yinchun Gong , Jun Deng , Xuehai Gong |
||
| To meet the requirements of strict fuel consumption and emission limits, continuously increasing the thermal efficiency of an internal combustion engine and decreasing its exhaust emissions are the main challenges to its sustainable development within the automotive industry. Considering the competition with other zero-emission powertrain systems, such as vehicle batteries and fuel cells, the development of the internal combustion engine needs to focus on producing higher efficiency and zero emissions to meet the request of CO2 reduction. This paper introduces two novel concepts for an internal combustion engine featuring high efficiency and zero emissions. Referred to as the argon power cycle engine fueled with either hydrogen or natural gas within an oxygen–argon mixture, its fundamentals and characteristics are expounded. This includes a method necessary to absorb carbon dioxide when natural gas is used as fuel instead of hydrogen. | |||

Effects of Cell Microtopology on the In-plane Dynamic Crushing Analysis of Re-entrant Square Cellular Material Fangwu Ma , Ying Zhao , Hongyu Liang , Jiawei Wang |
||
| With the development of three-dimensional printing technologies, so-called cellular materials have achieved increasing attention due to outstanding properties. Unlike pure solid structures, properties of cellular materials are influenced by both utilized material and cell microtopology. The present paper proposes a novel type of re-entrant square cellular material. To explore the relationship between microtopology and macrodynamic responses systematically, an explicit dynamic finite element simulation method is used. This work starts by constructing theoretical models of relative density employing a two-dimensional unit cell. Then, the effects of geometric features and configurations on dynamic properties are explored, and simulations indicate that variations of geometric parameters strongly affect properties and that the staggered re-entrant squares are more stable than the regular re-entrant squares. Subsequently, the effects of the impact velocity on dynamic crushing behaviors are elaborated. On this basis, the relationship of unit mass energy absorption and geometric features is obtained by employing the response surface method. Furthermore, with targets of maximum unit mass energy absorption and minimum relative density, the optimal structural parameters are achieved by using non-dominated sorting genetic algorithm. The study provides a detailed introduction to dynamic behaviors of cellular materials and guidance to design new structures with superior characteristics of energy absorption. | |||

The standardization work of China Society of Automotive Engineers (China SAE )was started earliest in 2006. With the deepening of national standardization reform, China SAE has successively undertaken the pilot works of association standards for government transfer function and the standardization administration of china (SAC) as one of the first batch of pilot units. Up to now, 87 standards has been issued and 97 standards is undergoing research, which covers the emerging technology fields of electric vehicles, intelligent connected vehicles, fuel cell vehicles, automobile lightweight, as well as the general technology fields of automobile fuel and lubricant, automobile electromagnetic compatibility, automobile reliability, automobile anti-corrosion aging, automobile aerodynamics, tire dynamics, etc. In 2018, 《Testing Methods and Requirements for Electromagnetic Compatibility of Automotive Electrical Parts and Subsystems (12V) 》(T/CSAE 63-2017) and《General Technical Requirements for Rolled Differential Thick Plates for Automobile》(T/CSAE 59-2017), were selected as "100 group standard application demonstrations of Ministry of Industry and Information Technology". China SAE is expected to issue 50 new standards in 2019，including drive motors, new system power batteries, fuel cells, V2X, ADAS, etc. If you have interest on the group standards, you could contact Technology and Standards department of China SAE via dyc@sae-china.org.
