ArchiveTo improve the quality of new energy vehicle monitoring data, a systematic abnormal data identification and quality evaluation scheme is proposed. The scheme addresses various abnormal situations in the monitoring data and designs a comprehensive evaluation process from data collection to data analysis. This process covers key dimensions such as data standardization, completeness, accuracy, consistency, and timeliness. The weights of each dimension are calculated using a combination of the Analytic Hierarchy Process (AHP) and the entropy weight method. Through the fuzzy comprehensive evaluation method, the data quality score is quantified, avoiding the influence of single subjective or objective factors on the evaluation results. Empirical analysis shows that this scheme can comprehensively identify abnormal data types in new energy vehicle monitoring and provide reasonable quality evaluation results.
In order to better meet the intelligent needs of users for new energy vehicles, a sampling survey method is adopted to cover user samples from three different segmented markets: high, medium, and low. Based on user demand data for product intelligent functions, corresponding analysis is used to explore the feedback and preferences of users in different segmented markets for the use of product intelligent functions. The results indicate that there are significant differences in the demand for intelligent functions among users in different segmented markets, showing that as the market level increases, consumers’ dependence and frequency of use of in car intelligent functions also increase. In addition, the automotive market has shown a gradual progression from meeting basic material needs, enhancing emotional connections, to achieving personal spiritual pursuits from low-end to high-end. Based on the results of this research, direction can be provided for optimizing and improving product intelligence related functions. At the same time, intelligent function development and design can be carried out according to user needs and preferences, further enhancing the user’s driving experience.

The rapid development of automotive intelligent technology has led to increased complexity of vehicle functions and a surge in the number of document developments, posing new challenges for the analysis of traditional vehicle electrical faults. In order to enhance the capability of electronic and electrical fault analysis and diagnosis, an intelligent diagnostic technology is utilized to construct an electrical data analysis model, which aids in the intelligent analysis and localization of faults in the automotive electrical system. The model construction is divided into two steps: firstly, the collection and preprocessing of electrical test data, including message parsing, data cleaning, and feature extraction; secondly, the use of deep learning algorithms to build a fault analysis model, achieving intelligent fault analysis and localization through model training. The proposed automotive electrical data analysis model based on intelligent diagnostic technology is capable of efficiently parsing complex electrical test data, realizing intelligent fault analysis and localization, and providing strong support for the troubleshooting of electronic and electrical faults.
In order to improve the safety performance of automobiles and provide effective data support for the evaluation of automobile safety performance, the relevant requirements of the national standard GB 39732—2020 “Vehicle Event Data Recording System” for the data recorded by EDR are deeply analyzed, and the compliance judgment of EDR data of different manufacturers and models under various working conditions is carried out. The results show that the data that must be recorded according to the standard GB 39732 for all vehicle models is generally complete, but there are still imperfect data records under special driving conditions. Finally, some suggestions are put forward for the data that should be included in the recording scope of new energy vehicles when accidents occur.
At present, the development of electrification of heavy-duty trucks has ushered in an important development opportunity. Building a green energy freight transport system based on electricity has become a consensus for the low-carbon transformation and development of freight transport in the transportation industry. Among them, the selection of typical freight scenarios and the matching of the performance of new energy trucks are crucial. Based on the overall cost analysis method, this article studies the economy of heavy-duty trucks under different technical routes such as traditional fuel, rechargeable pure electric, and exchangeable pure electric (self-owned or leased) in typical application scenarios in the Nangang Port area of Tianjin. This study finds that pure electric heavy-duty trucks in the Nangang Port area application scenario have cost advantages over traditional fuel heavy-duty trucks, with the exchangeable pure electric heavy-duty trucks having lower TCO costs.
The Chinese automobile market is undergoing a transition from being driven by quantity to pursuing high-quality development. With intense domestic market competition, Chinese automotive brands must actively explore international markets to achieve a transformation from big to strong. However, tapping into overseas markets entails facing multiple challenges such as geopolitical risks, trade barriers, and sociocultural differences. In response to the complexity and diversity of overseas automobile markets, based on China’s automobile export data, this study analyzes the characteristics of China’s automobile exports and the opportunities and challenges faced by China’s automobile exports through literature research, quantitative analysis, qualitative evaluation, expert surveys, and other methods. The research reveals that China’s automobile exports exhibit characteristics such as new energy vehicles gradually becoming the core driving force, diversification of export regions, and premiumization of export prices. Although there are opportunities for China’s automobile exports, a lot of challenges such as rising trade protectionism, intensifying overseas competition, and lagging electric vehicle infrastructure still exist. Addressing the challenges faced by automobiles going overseas, this study proposes localization strategies for overseas expansion, including localized research and development functions, localized manufacturing, localized marketing, and localized after-sales services.
