The rise of the Internet has brought automobiles into the era of intellectualization. The first generation of locomotives has developed to the intelligent locomotives. Not only have locomotive functions expanded from single music playing to navigation，entertainment，car control and other functions，but also the interactive mode has undergone a subversive change from key-press to touch-control. Through the research on the user data of intelligent locomotive，the user needs are deeply excavated，and the future development trend of intelligent locomotive is predicted. With the advent of the era of experience economy，user experience has become the focus of competition. Five years ago，only luxury cars equipped with in-vehicle control system has gradually become popular. As an important step for consumers to perceive smart cars，human-machine interaction（HMI）directly determines users’first impression of the smart car system and affects their purchase decisions. This paper divides the current development of HMI into two directions：traditional automobile enterprises and new energy vehicles. Based on the analysis of the current development situation，the characteristics of the current interactive system are summarized. It is pointed out that the combination of industry，University and research to build an interactive evaluation system and standards for automobiles，and the introduction of database tools are powerful for the rapid and healthy development of the industry.
