[0049] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0050] Please refer to FIG1 , which is a flow chart of a fault detection method in an embodiment of the present application, the method comprising the following steps:

[0051] S101. When a decoder reads a fault code, determine whether the fault code has an associated target data stream and / or target action test.

[0052] In the embodiment of the present application, an association relationship may be established in advance between a fault code that cannot be directly used to accurately locate the fault and related data streams and action tests.

[0053] When a fault code is interpreted, it is first determined whether the fault code has at least one of an associated target data stream and a target action test.

[0054] It should be noted that a fault code can be associated with both a data stream and an action test, or can be associated with a data stream or an action test alone. There can be one or more data streams, and accordingly, there can be one or more action tests.

[0055] In a specific implementation of the present application, determining whether a fault code has an associated target data stream and / or target action test includes:

[0056] Use the decoder to check whether the fault code can be found from each data stream or action test item;

[0057] If yes, the corresponding data stream is determined as the target data stream, or the corresponding action test is determined as the target action test.

[0058] For ease of description, the above steps are combined for explanation below.

[0059] In the embodiments of the present application, when determining whether a fault code has an associated target data stream or target action test, a decoder can be used to search for the fault code from each data stream or action test item. If the fault code can be found, the corresponding data stream is determined as the target data stream, or the corresponding action test is determined as the target action test.

[0060] The fault code has a fault code number; accordingly, the decoder is used to check whether the fault code can be found from each data stream or action test item, including:

[0061] Use the decoder to find the fault code number of the fault code from the associated list;

[0062] If the fault code number is found, confirm that the fault code is found;

[0063] In the event that the fault number is not found, it is determined that the fault code is not found.

[0064] That is to say, you can check whether the fault code can be found in each data flow or action test item. The fault code will have a number, that is, the fault code number, which can be specifically in the form of a string. When adding a data flow or action test, you can set a list of fault code numbers associated with the data flow ID or action test ID), that is, data flow ID / action test ID->fault code number.

[0065] In a specific implementation of the present application, determining whether a fault code has an associated target data stream and / or target action test includes:

[0066] Get fault code information of fault code;

[0067] If the fault code information is bound to a data stream or an action test, determining that the fault code has an associated target data stream and / or target action test;

[0068] If the fault code information is not bound to a data stream or an action test, it is determined that the fault code has no associated target data stream and / or target action test.

[0069] For ease of description, the above steps are combined for explanation below.

[0070] By checking the fault code information, determine which related data streams or action tests are bound. Each fault code number is bound to which data stream or action test ID, that is, fault code number->data stream ID / action test ID.

[0071] In this way, based on the fault code information, the target data flow and target action test can be determined.

[0072] S102: If the fault code does not have an associated target data stream and / or target action test, no operation is performed.

[0073] S103: If the target data stream exists, use the target data stream to locate the fault.

[0074] If there is a target data stream, the target data stream can be interpreted to locate the fault.

[0075] In a specific implementation of the present application, locating a fault using a target data stream includes:

[0076] Determine whether the target data flow is abnormal;

[0077] If yes, the device collecting the target data stream is determined as a faulty device.

[0078] The determination of whether the target data stream is abnormal can be specifically to determine whether the target data stream is abnormal by determining the value of the target data stream, data change trend and other information. If the data stream is abnormal, it is determined that the device collecting the target data stream is faulty and is determined to be a faulty device.

[0079] For example: if the target data stream corresponds to voltage and current, the actual fault situation can be judged according to the specific value of the target data stream. If the data stream value is abnormal (for example, the system voltage is greater than 14V, and the general voltage is 8-13V which is normal), it is determined that a sensor used to detect voltage is faulty.

[0080] S104: If a target action test exists, locate the fault by executing the target action test.

[0081] When it is determined that there is a target action test, the target action test can be executed to determine whether there is a problem with the component based on whether the corresponding component can be successfully executed.

[0082] In a specific implementation of the present application, locating a fault by performing a target action test includes:

[0083] Perform target action tests;

[0084] If the execution fails, it is determined that the control component performing the target action test is faulty;

[0085] If the execution is successful, it is determined that the sensor for collecting information from the control component is faulty.

[0086] For example: If the fault code indicates that the door control module has lost communication with the vehicle, an action test can be performed to check whether the door locking or window rising and falling are performed normally. If the window does not rise or fall, the problem can be narrowed down to the window-related sensor.

[0087] The vehicle's ECU stores the hexadecimal numbers of the fault codes, which can be obtained through diagnostic software, and the meaning of the numbers can be parsed by the diagnostic software. ECU (Electronic Control Unit), also known as the "on-board computer" of the car, is used to control the driving status of the car and realize its various functions. Its principle is to use various sensors and bus data collection and exchange to determine the vehicle status and the driver's intention and control the car through actuators.

[0088] That is, from the analysis of the fault code content, it can be concluded that there is a problem with the door control module, and specifically where the problem is in the module. Listed here are checking the electric windows and checking the relevant circuits of the doors. If the electric windows cannot rise or fall, then there may be a problem with the sensor, and the problem of the door module can be narrowed down to the window part.

[0089] By applying the method provided in the embodiment of the present application, when the decoder reads a fault code, it is determined whether the fault code has an associated target data stream and / or target action test; if there is a target data stream, the fault is located using the target data stream; if there is a target action test, the fault is located by executing the target action test.

[0090] In this application, when a fault code is interpreted, it is first determined whether the fault code has an associated target data stream or target action test. If the fault code has an associated target data stream, the target data stream is used to locate the fault; if the fault code has a target action test, the target action test is executed to locate the fault.

[0091] Technical effect of the present application: After the fault code is interpreted in the present application, the fault will be further automatically located based on the data stream or action test associated with the fault code, which can make fault detection more accurate and efficient.

[0092] It should be noted that, based on the above embodiments, the embodiments of the present application also provide corresponding improved solutions. In the preferred / improved embodiments, the same steps or corresponding steps as those in the above embodiments can be referenced to each other, and the corresponding beneficial effects can also be referenced to each other, which will not be described one by one in the preferred / improved embodiments of this article.

[0093] In a specific implementation of the present application, it also includes:

[0094] When a fault code is selected, a data stream or an action test associated with the fault code is output;

[0095] Receive newly added new data streams and / or new action tests, and associate the new data streams and / or new action tests with fault codes.

[0096] For ease of description, the above steps are combined for explanation below.

[0097] When the maintenance technician selects a fault code, the relevant data stream or action test can be listed for the maintenance technician to analyze and judge the status of a certain device. The maintenance technician can add data streams or action tests by himself and save the data streams or action test items related to this fault code. In this way, when the fault code is encountered next time, the newly saved data stream or action test can be listed, which also improves the new inspection content and matters.

[0098] When listing related data flows or action tests, the last saved ones are used. If none have been saved, there is a default list that comes with the software.

[0103] The action-based fault locating module 103 is used to locate the fault by executing the target action test if there is a target action test.

[0104] By applying the device provided in the embodiment of the present application, when the decoder reads a fault code, it is determined whether the fault code has an associated target data stream and / or target action test; if there is a target data stream, the fault is located using the target data stream; if there is a target action test, the fault is located by executing the target action test.
