Embodiment Construction

[0059] Existingly, when diagnosing a detected vehicle, it is necessary to inquire through the OBD interface inserted in the vehicle before reading the data stream in the vehicle. In this way, the data stream of the vehicle can only be obtained after multiple interactions between the terminal and the detected vehicle. And sometimes the time to read the data stream is longer than the query time, resulting in the inability to quickly read the data stream of the vehicle. The core of the present application is to provide a vehicle data reading method, device, vehicle-mounted equipment, and computer-readable storage medium, so as to solve the above-mentioned technical problems.

[0060] In order to enable those skilled in the art to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the drawings and specific implementation methods. Apparently, the described embodiments are only some of the...

Abstract

The invention discloses a vehicle data reading method which comprises the following steps: judging whether a configuration file for reading vehicle data exists or not, the configuration file comprising an entry instruction for entering a system corresponding to an appointed data flow and a reading instruction for reading the appointed data flow; and if the configuration file exists, entering a system corresponding to the specified data stream according to an entry instruction in the configuration file, and reading the specified data stream. According to the vehicle data reading method and device, the designated data flow can be directly and circularly collected according to the configuration file during reading, multiple times of information interaction is not needed, the inquiry time needed by data flow reading is greatly shortened, the vehicle data reading efficiency is improved, real-time and rapid reading of the vehicle data is achieved, and the user experience is improved. In addition, the invention further provides a vehicle data reading device with the technical effects, vehicle-mounted equipment and a computer readable storage medium.

Description

technical field [0001] The present application relates to the technical field of vehicle control, in particular to a method and device for reading vehicle data, vehicle-mounted equipment and a computer-readable storage medium. Background technique [0002] OBD (On-Board Diagnostic, On-Board Diagnostic System) can monitor the operating status of the engine and the working status of the exhaust after-treatment system at any time. Once it finds that it may cause excessive emissions, it will immediately issue a warning. When the system breaks down, the malfunction light (MIL) or the check engine (Check Engine) warning light is on, and the OBD system will store the fault information in the memory, and the relevant information can be read in the form of fault codes through standard diagnostic instruments and diagnostic interfaces . According to the prompt of the fault code, the maintenance personnel can quickly and accurately determine the nature and location of the fault. [00...
