High-definition, integration, and intelligence are the development directions of automotive instrumentation

Automotive instrumentation may seem simple, but this is not the case. As the vehicle information center, the screen is its display carrier, and the displayed content is its core. The display content comes from the various electronic control units on the vehicle communication system and can be regarded as a display window for the integration capabilities of the vehicle's electronic system. This area not only embodies the technical strength of the engineer's design, but also can display the designer's aesthetic perspective, can provide higher value-added electronic products for auto OEM manufacturers, match the models more perfect personality, provide consumers with more Diversity of choices and personalized driving experience.

From the perspective of industry trends, high-definition, integration, and intelligence are the three major directions for automotive instrumentation. HD is mainly reflected in the display effect. In the next two to three years, a 1920×720p monitor will be available on the market and gradually become popular. If you look further into the line of sight, you can expect to see 1080p HD displays used in cars. The 24-bit color TFT display that is being rolled out gradually has a very high degree of color coverage, allowing drivers to see images that are almost photo-realistic, and the video effects will be perfect. The contrast will be further increased to 1000:1, even under strong light. In terms of display content, as the size of the TFT screen continues to increase, the space for configurable content is increasing. In addition to the traditional information such as the speed, rotation speed, oil level, temperature, gear position, and failure, the running status of the vehicle Information, entertainment information, and even some of the navigation information that originally belonged to the central control can be integrated into the dashboard, providing manufacturers with greater room for design. Intelligence is mainly embodied in connected cars. With the development of automobile interconnection technologies, a series of active safety technologies will be widely used in future cars. Driver assistance information such as lane keeping and blind spot monitoring will be displayed on the dashboard.

Whether it is the most common hybrid meter in the industry or a digital instrument that has gradually emerged in the luxury car market, both the symmetrical and asymmetrical layouts can be adopted from the design perspective. Symmetrical design, such as the speedometer and tachometer, separates the left and right sides, with fuel gauges and thermometers placed underneath. If the customer needs more hands, it can provide oil pressure (O), battery voltage or power (B), and leave information settings, alarms, entertainment information, etc. in the middle. If there is still space left, you can put some alarm symbols or a simple gear function. Asymmetric design can make the instrument configuration more patchwork, such as in a hybrid instrument, the TFT display is placed on the right rather than the middle.

Based on the integration capabilities of the suppliers and the development of future technologies, the dashboard will be able to display more safety and entertainment information, such as front and rear images based on camera acquisition, some navigation and entertainment information provided by the entertainment system, and electronic control units. Energy meter, battery meter, mixing and automatic start and stop functions. This information can be customized and co-developed according to the needs of vehicle manufacturers, providing consumers with higher product added value.
