Embodiment 1

[0038] Such as figure 1 As shown, it is only one of the embodiments of the present invention. The present invention provides a method for executing a host computer based on UDS diagnosis. The method includes the following steps:

[0039] S1: The upper computer reads the real-time message information of the vehicle;

[0040] First, the host computer acquires the real-time message sent by the ECU processing center of the vehicle and reads the real-time message information for processing.

[0041] Of course, before step S1 is executed, the vehicle is connected to the host computer, so that the host computer can obtain real-time messages from the vehicle.

[0042] S2: Determine whether the message information is a communication message or a diagnostic message, if the message information is a communication message, then perform step S3, otherwise, if the message information is a diagnostic message, then perform step S4;

[0043] Before the host computer processes the real-time me...

Embodiment 2

[0063] still as figure 1 As shown, it is still one of the embodiments of the present invention. In order to make the UDS diagnosis-based upper computer execution method of the present invention safer and more stable, and the parking more convenient, the present invention also has the following designs:

[0064] Firstly, when step S2 is executed, the method of judging that the message information is a communication message or a diagnostic message is to interpret the message information, and it can be determined that the message information is a communication message or a diagnostic message.

[0065] Then, when step S3 is executed, after the communication message is filtered and interpreted, the message information is displayed to the host computer. It is convenient for the upper computer to record, and it is also convenient for the operator to obtain the status information of the current message execution.

[0066] Moreover, in step S4, after the negative response code is issu...

Abstract

The invention provides an upper computer execution method based on UDS diagnosis and relates to the vehicle diagnosis information technology field. The method comprises the following steps of S1, reading real-time vehicle message information by an upper computer; S2, determining whether the message information is a communication message or a diagnosis message, if the message information is the communication message, executing a step S3, and if the message information is the diagnosis message, executing a step S4; S3, filtering and interpreting the communication message; S4, determining whethera diagnostic service identifier, length check, and safety check in the diagnosis message satisfy a requirement, if the requirement is satisfied, executing a step S5, otherwise, emitting a negative response code; and S5, executing an application, determining whether the application satisfies an execution requirement, if the execution requirement is satisfied, executing the application, otherwise,emitting an execution failure code. By using the upper computer execution method based on the UDS diagnosis, operation is stable, convenient and reliable, diagnosis is rapid, operation personnel canconveniently, accurately and rapidly determine an implementation state, and exploitation tool cost is low.

Description

technical field [0001] The invention relates to the technical field of automobile diagnosis information, [0002] In particular, the present invention relates to a UDS-based diagnosis method for an upper computer. Background technique [0003] Automobile fault diagnosis technology started in western developed countries in the 1960s. With the increasingly complex structure of automobiles, it is necessary to have corresponding diagnostic methods to meet the needs of its maintenance. Therefore, automobile diagnostic technology has made great progress in the past few decades. rapid development. [0004] With the development of diagnostic technology through the stage of manual inspection, the use of simple instruments and meters for measurement, the stage of comprehensive diagnosis using special equipment, and the development of four stages of artificial intelligence diagnosis, the current automobile diagnosis is tending to be gradually perfected. [0005] In the development st...
