Integral display and operation system of vehicle cab

Abstract

A centralized display and control system of automobile driving desk consists of central processor, display screen, extension unit of data interface, interface unit of video device, operation key set and environmental brightness transducer. It is featured as using a planar display screen to replace all driving instruments and display system of vehicle equipment, using said display screen to carry out centralization display for all data information and video information of vehicle and using operation key set to carry out centralization control on various vehicle systems.

Description

technical field [0001] The invention belongs to the field of automotive electronics, and relates to a display and control system, in particular to a centralized display and control system for an automobile driving platform. Background technique [0002] The application of electronic technology in modern automobiles is becoming more and more extensive. Various electronic sensors and microcontrollers (MCUs) with excellent performance are continuously used in automobile systems, and the proportion of electronic devices in automobile manufacturing costs is getting higher and higher. , In some luxury cars, it even reaches half. The extensive application of advanced electronic technology has continuously improved the technical performance of automobiles, and the economy and comfort have also been greatly improved. [0003] However, with the continuous great changes in automotive electronics technology, the display mode of the car instrument has hardly changed, and the traditional...

Problems solved by technology

However, because of the display method of the watch needle, it is necessary to convert these digital information into a driving signal for driving a stepping motor or an electromagnetic watch movement through a dedicated integrated circuit, and drive the rotation of the mechanical watch needle to display this information. It can be seen that this simple The process is artificially complicated

[0005] Moreover, in this link, dedicated integrated circuit technology and stepping motor technology for instruments are still in the hands of several large foreign companies. Compared with them, domestic manufacturers have a relatively large technological gap and fewer replacement methods, so they have to import them at high prices. , which not only increases the manufacturing cost of the car and wastes resources, but also increases the difficulty of assembly and maintenance work, which is very uneconomical

[0006] At the same time, there are more and more vehicle-mounted electronic systems in modern cars, such as audio systems, automatic air conditioners, car phones, positioning and navigation systems, etc. Surveillance cameras, radar collision avoidance, and computer multimedia systems have also appeared on some luxury cars. Each has its own operation and display system, each of which is composed of systems, each working independently and not related to each other, resulting in the layout of the bridge becoming more and more crowded and scattered

At the same time, it also leads to an increase in the cost of automobile manufacturing, and the operation becomes more and more complicated.

To operate these devices when driving a vehicle, people need to constantly adjust their sight to find the operation buttons and the display, which not only makes the operation inconvenient, but also increases the work intensity, which brings great safety hazards to car driving.
