A multi-function car digital instrument system

Abstract

The invention relates to a multifunction automobile digital instrument system which comprises a liquid crystal screen and an embedded singlechip fixed on the back of the liquid crystal screen; sensor data is still read through a bus interface of the prior analogue instrument board, without changing the installation structure of the prior vehicle instrument board. The system is provided with all functions of the prior analogue instruments of an automobile, besides, the system is also provided with functions such as monitoring vehicle running state and fault diagnosis, monitoring driving state of drivers, monitoring vehicle discharge state, vehicle traveling recorder, video reversing radar, GPS navigation, GPRS wireless data transmission and so on. The multifunction automobile digital instrument system of the invention can greatly expand functions of the prior instrument board and make the prior instrument board to be the information processing center of modern automobiles. The application of the system contributes to improving the service life of vehicles, reducing accidental faults, improving the safety of running and driving of vehicles, reducing the cost of use and management of vehicles and realizing informatization of traffic guidance.

Description

technical field [0001] The invention relates to a multifunctional automobile digital instrument system, which belongs to the field of automobile electronic engineering. Background technique [0002] With the development of the economy, the price of cars will gradually drop, and more and more people will buy cars. The increase of vehicles will lead to an increase in traffic accidents, and the traffic safety situation is very severe. How to ensure the safe operation of vehicles has become a hot spot of concern. Although electronic technology is widely used in vehicles at present, active safety systems such as ABS, parking sensors, infrared anti-collision systems, etc. and passive safety systems such as air bags are widely installed, and the adoption of these technologies has greatly improved driving safety. However, the above technologies cannot eliminate the potential safety hazards caused by sudden car breakdowns, driver fatigue and abnormal driving. At the same time, they ...
