At present, automobiles have become an indispensable part of the society, which not only promotes the further development of the transportation industry, but also makes people's travel more convenient. Nowadays, most of the vehicles are gasoline-based, and the number of people using automobiles is constantly increasing. The industry is also developing, and people's demand for fuel resources is also increasing, which has caused great pressure on petroleum resources. Although the automobile can bring us some convenience, it will also rapidly consume the non-renewable resource of oil. The continuous progress of technology means that the automobile energy should also be optimized and reformed. In order to protect the resources accordingly, enterprises also need to choose the appropriate development direction, gradually research and develop new energy vehicles and put them into the market, so as to ensure the development of automobile related industries in a new direction.

Because the classic PID control doesn’t satisfy the demand of automobile ABS in all conditions and it is short of an ability of identifying road surface, fuzzy control is short of an ability of remove systemic stable error and it doesn’t make automobiles keep higher control precisions. a dynamic mode of the wheels is built when an automobile is braking at first, aiming at automobile ABS, a immune PID control algorithm based on classic PID is presented and used in automobile ABS system. Compared with the classic PID control algorithm and fuzzy control algorithm, the simulation result shows that the immune PID control algorithm has a shorter stabilization time, a smaller excess of system output, fewer response time and shorter braking distance, it is superior to the classic PID control algorithm and fuzzy control algorithm. The immune PID control algorithm has a higher application value.

This study intends to compare Japanese automobiles, German automobiles, and Korean automobiles, which are major competitors in the US automobile market, in light of major sales factors, and to draw implications for expanding sales of Korean automobiles in the US. This study compares and analyzes Korean cars, Japanese cars, and German cars by sales factors in the 50 US states instead of country level determinants considered in previous studies. In this respect, it makes differentiated contributions. This study adopts the fixed-effect model estimation using panel data as a research method. First, it performs the estimation using the size of Korean automobile imports, Japanese automobile imports, and German automobile imports as dependent variables. Furthermore, this study estimates the fixed-effect model for Korean automobile imports relative to Japanese automobile imports and Korean automobile imports relative to German automobile imports. According to the research results of this study, the size of imports of Korean automobiles and Japanese automobiles is affected by efficient fuel use or fuel price such as highway fuel efficiency and fuel price. On the other hand, German car imports are not affected by fuel prices and are inversely related with the highway fuel economy. Another finding of this study is that the higher the ratio of fatalities in highway traffic accidents, the lower the Japanese automobile imports. In addition, this study finds that the ratio of single-driver commuting to work has inverse relationship with the German automobile imports. Lastly, it is found that automobile imports from Korea and Japan are found to be affected by overall preferences for products in those countries. Meanwhile, as a result of controlling for major sales factors, Korean cars, Japanese cars, and German cars are equally preferred in California, Florida, Michigan, Virginia, and Rhode Island. In Mississippi, South Carolina, Oregon and Tennessee, Korean and Japanese cars are preferred over German cars while Korean cars and German cars are preferred over Japanese cars in New Jersey, Georgia, and Texas. On the other hand, in Louisiana, Washington, and Pennsylvania, Korean-made cars was found to be remarkably preferred over German and Japanese cars. The results of this study provides a guideline for sales strategy for Korean cars in the US market. This study limits the subjects of imports of Korean cars, Japanese cars, and German cars to 50 states in the United States, and only categorizes cars by production country rather than automobile brands. If these data can be accessed, various studies will be possible in the future.

Since awareness has increased for environment protection, it is being global concerns for consumers and manufacturers to use green and environmentally friendly products with realisation to contribute to saving of environment. In this context, automobile sector has very important contribution in an economy of any country. A very large percentage of automobiles are using fuel, Co2 emissions have adverse effect on environment, and this is one of contributing factor for global warming. This study aims to investigate the effect of environmental values, responsibility feelings and environmental knowledge upon purchase intentions of Pakistani consumers towards environmentally friendly automobiles. This study utilises the causal research approach by testing the correlation existing between an individual’s environment attitude and its impact on his/ her intentions to purchase environment-friendly automobiles. It was found that there is a demand for environment-friendly automobiles amongst Pakistani consumers. However, at this stage they do have feelings of responsiveness towards environment protection and sustainability but are not willing to pay extra to purchase a hybrid or environment-friendly automobile. Furthermore, they are not willing to compromise on quality and comfortability when purchasing an environment-friendly automobile compared to a regular car. Contrary to this, they may be willing to settle for a relatively unattractive design and lower performance when buying an environment-friendly automobile compared to a regular automobile.

Purpose This study analyzed how Japan’s export regulations affected the imports and exports of the automobile industry, and examined whether there was a change in the trade competitiveness of the automobile industry. Design/Methodology/Approach In order to examine the degree of improvement in the automobile industry’s imports, exports, and trade competitiveness with Japan in Korea, the world and Japanese import and export statistical data of the automobile industry were aggregated for five periods. In addition, the change trend in the dependence on imports and exports of automobiles and parts to Japan was examined. In addition, the change in competitiveness of the Korean automobile and parts industry to Japan was examined using the trade specialization index. Findings As a result of the analysis, it was found that the trade deficit of automobiles and parts with Japan in 2021 fell compared to 2017 and 2019. In the case of import and export dependence, there was little change in export dependence, but it was confirmed that there was a significant decrease in import dependence. Korea’s dependence on exports of automobiles and parts to Japan has decreased slightly, but its dependence on imports has decreased by 10 times, which can be interpreted as Japan receiving more trade losses in the automobile industry due to the Korea-Japan trade dispute. Research Implications In the passenger car sector, it can be evaluated that there has been a result of the boycott of Japanese products, and efforts to strengthen the competitiveness of domestic cars and diversify import lines should continue to continue this in the future. In addition, in order to continue this performance in automobile parts, efforts should be made to improve product competitiveness and import dependence in more diverse item groups in the parts.

Luxury is often blamed for creating social inequality and hampering sustainability, especially in the social and environmental realms. For instance, luxury goods entice people to conspicuous consumption that may result in showing off. However, study results show that luxury and environmental sustainability have common features. Notably, previous research mainly examined motivations for green purchases in general without relating to the specific product categories such as durables. Therefore, this study examines the relationship between these two—green and luxury automobile buying intentions—by analyzing the survey results of 1601 respondents relating to more than 60 nationalities. In contrast to a substantial effect on luxury buying intentions, perceived conspicuousness has no significant positive effect on green auto purchase intentions, and that price value has a limited influence compared with the effect on luxury automobile purchase intentions. Furthermore, hedonism has a less positive impact on green auto purchase intentions compared to its impact on luxury automobile buying intentions. The ‘extended self’ and the perception of high quality have been found to be drivers of luxury and green automobile purchase intentions, while unique value appears to have no impact on purchase intentions for green and conventional luxury automobiles. The present study contributes to the extant research by investigating common and contradictory motivations for luxury and green buying intentions of automobiles. Furthermore, it suggests a reconsideration of the traditional view that luxury and environmental consumption are inconsistent and contradictory concepts. The complementary managerial implications of this study guide practitioners in positioning the situatable variants of their automobiles as ethical luxury.

With automobile sales, market share also tends to stabilize. The growth rate of automobile sales is gradually decreasing. At the same time, the goal of maintaining high profits for automobile manufacturers is difficult to achieve only by "car production." As a component of brand equity, a brand premium has become essential for automobile manufacturers to improve profitability—the direction of development. Currently, the connotation and influencing factors of brand premium are still controversial in academic circles, and there are few particular kinds of research on brand premium in the automobile sales market. This paper takes the automobile industry as the research object and profoundly explores the concept and influencing factors of brand premium. On this basis, it proposes targeted suggestions for automobile manufacturers to improve their brand premium capabilities to encourage Chinese automobile manufacturers to achieve faster transformation and upgrading of industrial structure.

The purpose of this quantitative research was to identify whether there were correlations between U.S. automobile consumers’ perceived value and South Korean automobiles’ price, quality, fuel efficiency, design, and technologies. The sample size of the current study was 538. A questionnaire was used to collect data from automobile consumers in 50 states and in the District of Columbia. The results show that consumers’ perceived value were positively related to South Korean automobiles’ price, quality, fuel efficiency, design, and technologies. The result of a multiple regression analysis shows that South Korean automobiles’ quality, fuel efficiency, design, and technologies were significant predictors of consumers’ perceived value. On the other hand, price was only a marginally significant predictor of consumers’ perceived value. In the second multiple regression analysis which considers the participants’ gender, age, education level, and income level, results indicated that none of the four variables had any effect on consumers’ perceived value. Implications for South Korean automobiles’ pricing, quality control, and manufacturing strategy are discussed. Directions for future research are also proposed.

The globalization of the automotive industry in the last twenty years has manifested itself ina rapid increase in the assembly of automobiles and the production of automotive components and spareparts outside of the traditional centers of automotive manufacturing. On the basis of contemporary researchand literature, we can distinguish two types of emerging centers of automobile manufacturing.First are potentially large domestic markets with a low level of motor vehicle ownership and rapidlygrowing economy such as Brazil. The second type of new automobile manufacturing center consistsof the peripheries of automotive core regions such as Mexico in the case of the North American coreregion and Central Europe in the case of the Western European core region. These new growth centershave benefitted from their lower production costs compared to those of core regions and their geographicproximity to the largest automobile markets. These emerging centers of manufacturing havebecome attractive locations, especially for export-oriented manufacturing facilities operated by largetransnational automotive corporations attempting to improve their global competitiveness. The purposeof this paper is to evaluate the effect of foreign direct investment on the development of automobile productionin these three emerging regions. The paper reviews post-1990 production trends and changes inthe geography of automobile production, especially new greenfield investments in the three analyzedregions. We examine changes in international trade in Brazil, Mexico and Central Europe with a focuson automobiles and automobile parts. Based on the results of our research, we determine the effects offoreign direct investment and industrial upgrading on the role of these emerging production centers inthe global production system.

Recent research has suggested that noise barriers have significant impacts on near-road automobile emissions reduction. T-shaped noise barriers have better performance on reducing noise than others, however, their effects on automobile emissions reduction are not clear. In this research, commercial software ANSYS®Fluent 19.2 (Ansys Inc., Canonsburg, PA, USA) was applied to simulate the noise barrier shape and different inflow wind shear condition effects on highway automobiles emission dispersion. Various Reynolds Averaged Navier-Stokes (RANS) models were tested. The realizable k-ε turbulence model was selected to simulate the turbulent flow caused by fast moving vehicles on highway based on the comparison results. A non-reacting species transport model was applied to simulate emission dispersion. Results showed that the T-shaped barrier was able to help reduce highway automobiles emission concentration in downstream areas more than the rectangular barrier. An optimized range of the T-shape was proposed; under the inflow condition without wind shear, the noise barrier shape effects on automobiles emission reduction were not significant.

Automobile side door glass squeaks and rattles during use. This abnormal noise can make the driver and occupants irritable and reduce the comfort of the automobile. This reduces the sales of this automobile. This paper analyzes and determines the cause of squeak and rattle during the lifting and lowering process of the side door glass of an automobile. The noise is due to four reasons. One is that the distance between the inner waterproof belt and the automobile side door glass of the automobile is unreasonable, causing excessive friction between the automobile side door glass and the inner waterproof belt during the automobile side door glass up and down movement. Other factors affecting squeak and rattle may be the distance between the automobile side door sheet metal and the automobile side door glass, the thickness of the automobile side door glass and the characteristics of the inner waterproof belt. The first two dimensions are analyzed using the 6 sigma method, and the structure of the inner waterproof belt is improved and the flocking position is adjusted. The squeak and rattle phenomenon is explained using the implicit dynamic analysis method ABAQUS, and the compression load deflection after the installation of the inner waterproof belt is 3–9 N/100 mm. This research completely solves the squeak and rattle problem caused by the up and down movement of the side door glass of the automobile. This research has significance for solving practical engineering problems.
