Automobile communication method and device and computer readable memory medium

Abstract

The invention discloses an automobile communication method and device and a computer readable memory medium. The method comprises the steps of receiving command data of a first protocol format of a terminal, and converting the command data of the first protocol format into the command data of a second protocol format according to the command data of the first protocol format and a preset mapping relationship; sending the command data of the second protocol format to an automobile device electronic control unit, thereby enabling the corresponding automobile device electronic control unit to respond to the command data of the second protocol format and return obtained response data of the second protocol format; and receiving the response data of the second protocol format, converting the response data of the second protocol format into the response data of the first protocol format according to the response data of the second protocol format and the preset mapping relationship, and feeding back the response data of the first protocol format to the terminal. According to the method, the device and the computer readable memory medium, when the automobile device electronic control unitmismatches a communication protocol supported by a diagnosis instrument, the communication between the automobile device electronic control unit and the diagnosis instrument can be realized, the applicability is high, and the development cost can be reduced.

Description

technical field [0001] The invention relates to the field of communication technology of automotive electronic engineering, in particular to an automotive communication method, device and computer-readable storage medium. Background technique [0002] With the wide application of electronic technology and computer technology, the communication technology of automotive electronic engineering has also been developed rapidly. The diagnostic instrument establishes a communication connection with the electronic control unit (ECU) in the vehicle and sends a command request to the ECU to obtain various fault diagnosis data or status data of the vehicle. At present, the ECUs of many automobiles already support the CAN communication protocol, but most diagnostic instruments still support the KWP communication protocol. The communication protocols supported by the two are different, resulting in the inability to realize communication between the two. [0003] To solve the above probl...
