Problems solved by technology

[0006] The existing vehicle information monitoring and display system does not adopt the above three information receiving methods at the same time, which has caused the common situation of incomplete acquisition of vehicle information. The performance of the system is also a limiting factor
[0007] At present, vehicle information is mainly displayed through instruments. Instruments obtain relevant signals through sensor devices closely related to the whole vehicle and calculate the data to display and drive the instrument panel. The matching requirements for sensors are very high, and special car matching is required for the characteristics of the car. Instruments Design changes may affect the overall performance of the instrument, the cost of the change is high, and it is not easy to expand the function
[0008] General car instrumentation mainly includes the basic information necessary for drivers such as speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging meter, etc. Many effective car information is limited by space design, single-chip performance, and the overall cost of the instrument. Restrictions, unable to expand its functions well, thereby reducing the driver's understanding of car information
[0009] With the rapid development of automobile intelligence, the types of automobile information have been greatly enriched, not only limited to the basic information related to engine work, but relying solely on the existing system of instruments can no longer meet the information transmission needs of automobiles to drivers

Abstract

The invention belongs to the field of automotive electronics and particularly relates to an automotive information display auxiliary system. The auxiliary system consists of an information receiving module and an information comprehensive processing module, wherein the information receiving module comprises an information acquisition and filter unit and an information extraction and structuralization unit; the information receiving module is used for monitoring and receiving information from vehicles and transferring the information to the information acquisition and filter unit; the information acquisition and filter unit is used for similarly filtering the information and then transferring the similarly filtered information to the information extraction and structuralization unit; the information extraction and structuralization unit is used for performing structural processing on the information according to the type of the information and the display requirements; and the information extraction and structuralization unit is used for transferring the information to in-vehicle display equipment. According to the automotive information display auxiliary system, more comprehensive automotive information is acquired without modifying an original automotive instrument system, and moreover, a data graphical and compression algorithm unit is arranged so as to meet the universality requirement of the display equipment, and richer automotive information is provided for users.

Description

technical field [0001] The invention belongs to the field of automobile electronics, in particular to an automobile information display auxiliary system. Background technique [0002] The existing vehicle information acquisition methods mainly include the following: [0003] 1. CAN stands for Controller Area Network, which belongs to the category of industrial field bus. Compared with the general communication bus, the data communication of CAN bus has outstanding reliability, real-time and flexibility. Because of its good performance and unique design, people pay more and more attention to CAN bus, and it is widely used in the field of automobiles. [0004] 2. OBD is the abbreviation of On-Board Diagnostics in English, and the Chinese translation is "on-board diagnostic system". OBD is connected to the electronic control unit (ECU) through various emission-related component information, and the ECU has the function of detecting and analyzing emission-related faults. Whe...
