Chapter One Introduction

1.1 Research background and significance

For the design of the car dashboard, it is not only a product planned according to various data, but also has an inevitable connection with ergonomics. Ergonomics requires cars to provide sufficient space for drivers and occupants, and needs to have good comfort, especially in the dashboard assembly, ergonomic problems are generally reflected in three directions: one is to determine the driver and The interval between the instrument panels; the second is to determine the optimal arrangement of the instrument panel relative to the driver according to the driver's position; the third is to choose a display type that is easy to transmit and display information and is conducive to rapid and accurate identification. These ergonomic constraints and considerations have obvious effects on the car dashboard. In response to the above requirements, based on the development process and various parameter ranges, on the basis of previous research, a set of instrument panel design layout and verification methods are summarized.

1.2 Research status

The development of the automotive industry in the field of new energy and automation is constantly improving, and the methods and creative requirements of automotive design are also constantly improving. But whether it is the development of new energy sustainable vehicles or the rapid advancement of Internet automated driverless technology, the personal experience of driver and passengers must be guaranteed, and the basis of these requirements is the continuous development of ergonomics. The development and application of ergonomics in automotive design have different development methods and directions in many countries. Many traditional brands choose to cooperate with universities or laboratories to study the deep application of ergonomics. Up to now, the research of ergonomics in automotive design has mainly concentrated on three major categories: automotive ergonomic design, digital human modeling, and driving comfort evaluation.

By constructing a digital model of the dashboard, Zhang Xiuqian of Hubei University of Engineering gave a brief description of the digital parameter design of the dashboard, and proposed the ergonomic digital design concept of the automobile dashboard.^[1]

Yin Mengjie of Xihua University, combined with relevant ergonomic theories, used virtual human models to study the car seat interface, control interface and display device interface and other related content, analyze the current design defects of car man-machine interface, research and design in accordance with Human-machine interface of car cab.^[2] After researching and analyzing the ergonomic design of automobiles at home and abroad, in the field of passenger car design at home and abroad, this article will combine the theoretical content of ergonomics of automobiles to study the design of 1.6L car dashboard.
