In this research, the interior noise of a passenger car was measured, and the sound quality metrics including sound pressure level, loudness, sharpness, and roughness were calculated. An artificial neural network was designed to successfully apply on automotive interior noise as well as numerous different fields of technology which aim to overcome difficulties of experimentations and save cost, time and workforce. Sound pressure level, loudness, sharpness, and roughness were estimated by using the artificial neural network designed by using the experiment values. The predicted values and experiment results are compared. The comparison results show that the realized artificial intelligence model is an appropriate model to estimate the sound quality of the automotive interior noise. The reliability value is calculated as 0.9995 by using statistical analysis.

Automotive safety is always the focus of consumers, the selling point of products, the focus of technology. In order to achieve automatic driving, interconnection with the outside world, human-automatic system interaction, the security connotation of intelligent and connected vehicles (ICV) changes: information security is the basis of its security. Functional safety ensures that the system is operating properly. Behavioral safety guarantees a secure interaction between people and vehicles. Passive security should not be weakened, but should be strengthened based on new constraints. In terms of information safety, the threshold for attacking cloud, pipe, and vehicle information should be raised to ensure that ICV system does not fail due to malicious attacks. The cloud is divided into three cloud platforms according to functions: ICVs private cloud, TSP cloud, public cloud.

Smart vehicles have become an important development direction of the transformation and upgrading of the automotive industry. Highly intelligent smart vehicles can free human drivers from driving tasks, endowing cars with the mobility and instrument properties. Smart cockpits integrate the media for interactions between humans and environments inside and outside cars. This paper has explored the components of smart cockpits, sorted out three development stages of smart cockpits from such three dimensions as man, car and environment, analyzed the characteristics of the second development stage (Stage 2.0), and illustrated the necessity of the competition between smartphones and head units at the second stage. Based on the comparison of merits and demerits between smartphones and head units, this paper has proposed three principles for an ideal division of duties of smartphones and head units.
