A comfort evaluation method based on an intelligent car cockpit

Abstract

With the rapid development of automobiles, car cockpits are becoming more and more intelligent and advanced, and the intelligent requirements of automobile cockpits are gradually increasing. However, the real value of intelligence can only be realized when it makes passengers in a cockpit feel comfortable. In this study, seven factors that affect passenger comfort in intelligent cockpits are defined. Under these factors, a total of 33 evaluation indicators were developed. The core of the method was to determine the dissatisfaction indicators and degree of dissatisfaction in the intelligent cockpit by analyzing the relationship between people's perceived performance and their expectations. This method was used to evaluate the Tesla Model 3, and it was found in the results that the higher the degree of dissatisfaction with the indicator, the more subjective feedback it had, which in turn proved the effectiveness of the model. According to the degree of dissatisfaction, the indicators affecting comfort were also divided into three levels. This hierarchical division helps clarify which indicators should be prioritized for improvement. Generally, this method has a certain feasibility, which is helpful for the development and redesign of an intelligent car cockpit, and provides some reference strategies for other transportation fields.comfort, evaluation method, expectation, intelligent cockpit, the degree of dissatisfactionWith the rapid development of technology, the number of intelligent cars has also increased in recent years (Arena et al., 2020). Related research describes the intelligent car of the future as not only improving traffic safety like a robot but also further meeting people's demands by connecting to the Internet (Huang et al., 2016;James, 2012). Intelligent vehicles have become a trend now. Companies such as Tesla, Jaguar, and Google are now launching more intelligent vehicles from innovative materials and innovative technologies (Sun et al., 2021).However, for the vast majority of consumers, it is not the technology itself that cares about them, but how they feel in the cockpit (Park et al., 2019). The benefits of intelligent cars include increased safety, reduced need for infrastructure investment, improved fuel economy, and reduced congestion. But most importantly, they make passengers more relaxed and comfortable (Jorlöv et al., 2017). The real benefits of intelligent cars can only be realized when the human driver is comfortable in the intelligent cockpit and the interaction between the driver and the automated system is at a reasonable level (Helldin et al., 2013). Beggiato et al. (2019 believe that comfort plays an important role in the wide acceptance of intelligent vehicles. For some products such as smart cars, consumer satisfaction is a factor for business success (Park et al., 2019;Salomo et al., 2003). Industry and research are working to develop systems that can automatically adapt to maximize well-being (Olugbade et al., 2021). Therefore, making people feel comfortable is

A new method to identifying optimal adjustment strategy when the car cockpit is uncomfortable: optimal state distance method

“…Since constant speed is the most common driving condition in real life, the experimental conditions for this experiment were all set to constant speed, with the speed controlled at about 40 km/h. Data were collected as previously described in Yang et al (2022a) and Yang et al (2022a) . The noise measurement instrument is a precision noise level meter, a model AWA6291 handheld real-time signal analyzer.…”

“…( Sun, Cao & Tang, 2021 ). The car cockpit has gradually become an intelligent interactive environment, developing towards a third space ( Yang et al, 2022a ; Yang et al, 2022b ). However, inadequate cockpit comfort can lead to human dissatisfaction and have negative effects on productivity and performance ( Budaiwi, 2007 ).…”

Intelligent Car Cockpit Comfort Evaluation Model Based on SVM

“…Comfort plays an important role in the widespread acceptance of intelligent cars. With the popularity of intelligent cars, users' understanding of the value of cars has gradually changed from a travel tool to a ''third living space'' [12]. Shortly, there will be more advanced intelligent cockpits, and people will spend more time and energy in the car cockpit to do more things besides driving, such as learning, entertainment, etc.…”
