The Development Trend

Adaptive cruise control (ACC) is an important part of the advanced driver assistance system (ADAS), which aims to improve the user’s driving experience by reducing their manual operation and optimizing the vehicles’ performance such as economy, comfort, and safety. With the gradual maturity of research on ACC, it presents various development trends. Among them, ecological adaptive cruise control (EACC) has great development potential in reducing emissions and improving driving range in internal combustion engine vehicles (ICEVs), hybrid electric vehicles (HEVs), and electric vehicles (EVs). This paper firstly reviews the components of classic ACC. Then the main design methods, research hotspots, and development trends of EACC for HEVs and EVs are introduced in detail. This paper not only provides a comprehensive analysis of EACC design and application in different type of vehicles but also forecasts the future research direction and trend, expecting to promote the further development of EACC efficiently.

The Development Trend

In recent years, artificial intelligence supported by big data has gradually become more dependent on deep reinforcement learning. However, the application of deep reinforcement learning in artificial intelligence is limited by prior knowledge and model selection, which further affects the efficiency and accuracy of prediction, and also fails to realize the learning ability of autonomous learning and prediction. Metalearning came into being because of this. Through learning the information metaknowledge, the ability to autonomously judge and select the appropriate model can be formed, and the parameters can be adjusted independently to achieve further optimization. It is a novel method to solve big data problems in the current neural network model, and it adapts to the development trend of artificial intelligence. This article first briefly introduces the research process and basic theory of metalearning and discusses the differences between metalearning and machine learning and the research direction of metalearning in big data. Then, four typical applications of metalearning in the field of artificial intelligence are summarized: few-shot learning, robot learning, unsupervised learning, and intelligent medicine. Then, the challenges and solutions of metalearning are analyzed. Finally, a systematic summary of the full text is made, and the future development prospect of this field is assessed.

Excellent Performance

Energy plays an important role in human society. With the development of science and technology, the increasing demand for new energy like electric energy cannot be ignored. The battery is the key component of electric vehicles which are the centers of future development. Lithium-ion batteries have great advantages in electric vehicle applications for their excellent performance. We need to find ways to improve lithium-ion batteries to promote the development of electric vehicles fundamentally. The high specific energy, low self-discharge, good cycling performance, no memory effect, and other advantages lead to the excellent performance of lithium-ion batteries. This paper reviews the unique merits of lithium-ion batteries compared with other important battery technologies in electric vehicle application in three main aspects and describes some methods to enhance the performance of lithium-ion batteries by improving the anode, cathode, and electrolyte, respectively. For instance, we can use LiNi1-x-yCoxMnyO2 (NCM) materials as cathode, silicon-based materials as anode with composite materials like FeOOH@rGO and SiNP@NC add more silicon in the composite anode structure and silicon nanowire anode to improve its mechanical stability. Also, with an example of their employment in the BMW i3 94 Ah vehicles, the application outlook of lithium-ion batteries in electric vehicles and their development trend in the future have been prospected. Although electric vehicles are becoming the ideal next-generation vehicles with the increasing environmental friendliness, the battery technology, such as its safety problem and the manufacturing cost, etc., remains a big challenge in the development of lithium-ion batteries in electric vehicles.
