Vehicle-mounted head-up display and OBD (On-Board Diagnostic) data processing method based on same

Abstract

The invention discloses a vehicle-mounted head-up display and an OBD (On-Board Diagnostic) data processing method based on the same. The vehicle-mounted head-up display comprises an OBD interface, an information processing device, a wireless transceiver and a display screen, wherein the information processing device is used for processing and analyzing OBD data and also used for controlling the display screen to display corresponding information according to an analyzed result; the wireless transceiver is used for receiving information processed and analyzed by the information processing device and transmitting the information wirelessly; and the display screen, the OBD interface and the wireless transceiver are respectively connected with the information processing device. By utilizing the vehicle-mounted head-up display, a user conveniently acquires fault information of a vehicle in real time, the immediate assistance is provided for the user to maintain the vehicle, the fault information is remotely monitored and known, the user can take along through storage equipment, so that a maintenance man does not need to arrive at the scene to read and judge a vehicle fault code, the maintenance flow is reduced, the maintenance time is shortened, and the user can use the vehicle-mounted head-up display quite conveniently.

Description

Technical field [0001] The invention relates to a vehicle-mounted system, in particular to a vehicle-mounted head-up display and an OBD data processing method based on the display. Background technique [0002] On-Board Diagnostics (OBD, On-Board Diagnostics) is a special environmental protection device that monitors vehicle emissions and promptly sends out warnings of exceeding standards. The system monitors whether the vehicle exhaust exceeds the standard at any time and whether the system is normal according to the operating conditions of the engine. When a failure of the emission system is detected (including emission-related failures such as reduced catalyst efficiency, misfire, and oxygen sensor failure) that cause vehicle emissions to exceed the specified limit, the OBD system records the failure-related code and failure-related information, and passes the point Turn on the fault light to remind the driver. At this time, the driver should go to the repair station to inspe...

Problems solved by technology

[0003] Most users do not know the meaning of the fault codes of the OBD system, and the car diagnostic information cannot be sent to the data center or where the user needs it, and the user needs to go to the repair station to read the OBD diagnostic information. When the car breaks down, the user What's more, it is impossible to quickly understand what is wrong with the car in real time.
