[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0030] It should be noted that the terms "first", "second", etc. in the specification, claims and drawings of the present invention are used to distinguish different objects, rather than to limit a specific order. The following embodiments of the present invention can be implemented separately, or in combination with each other, and the embodiments of the present invention do not impose specific limitations on this.

[0031] Figure 1 This is a flow chart of a control method of a diagnostic instrument provided by an embodiment of the present invention. The control method of the diagnostic instrument can be applied to any situation where the diagnostic instrument diagnoses a vehicle, and the control method of the diagnostic instrument can be executed by a control device of the diagnostic instrument, which can be implemented in hardware and / or software.

[0032] like Figure 1 As shown, the control method of the diagnostic instrument specifically includes the following steps:

[0033] S101, judging whether the first part number of the target controller is empty based on the controller data of the vehicle to be diagnosed, wherein the target controller is one of multiple target controllers contained in the controller data, and the first part number is a number uniquely corresponding to the target controller.

[0034] In the embodiment of the present invention, the vehicle to be diagnosed can be any type of vehicle to be repaired or maintained. Generally speaking, the vehicle to be diagnosed may contain multiple controllers. When the vehicle to be diagnosed fails or needs to be replaced, each controller can be diagnosed by a diagnostic instrument, and the replaced controller can be configured. When the diagnostic instrument is needed, it is necessary to connect the diagnostic instrument to the OBD (On Board Diagnostics) interface of the vehicle to be diagnosed and select the automatic scanning mode; after the diagnostic instrument is connected to the vehicle to be diagnosed, the diagnostic instrument will read the vehicle model code from the vehicle to be diagnosed, and then obtain the vehicle model information of the vehicle to be diagnosed from the manufacturer's server through the vehicle model code, that is, the above-mentioned controller data. Specifically, the controller data mainly includes: controller name, controller part number (that is, the above-mentioned first part number), controller software version number and controller configuration code.

[0035] Specifically, the controller name includes the Chinese name (English name) of the controller, such as the engine control unit (EMS); the part number of the controller refers to the inherent property of the hardware. The same part number of the same controller must be different for different controllers, and the part numbers of controllers with the same name are not necessarily the same; if a part number under a certain vehicle model is empty, it means that the controller corresponding to this part number is not installed in this vehicle model; for the controller configuration code, since different functions can be distinguished by configuring the same version of software, the configuration codes will be different for different vehicle models.

[0036] After obtaining the controller data of the vehicle to be diagnosed, since there are multiple controllers in a vehicle to be diagnosed, the controller data contains multiple target controllers, and the multiple target controllers are arranged in serial numbers. The diagnostic instrument will scan the controller data in the order of the target controllers, and determine whether the first part number of each target controller is empty in turn.

[0037] S102: If it is not empty, determine the number of diagnostic databases matching the target controller based on the name of the target controller.

[0038] Specifically, if the diagnostic instrument determines that the part number of the target controller is not empty, indicating that the vehicle to be diagnosed is equipped with a corresponding target controller, the diagnostic database is searched based on the name of the target controller, for example, based on the English name of the target controller (such as EMS), to determine the number of diagnostic databases matching the target controller. The diagnostic database is a program file stored in the diagnostic instrument, which is composed of ODX files and contains all diagnostic information of the corresponding controller.

[0039] S103, if it is determined that the number of matching diagnostic databases is greater than 1, determine whether the second part numbers in multiple diagnostic databases are the same, wherein the second part number is the number of the controller pre-stored in the diagnostic database.

[0040] Specifically, if more than one diagnostic database matches the target controller, it is further determined whether the second part number in each of the multiple diagnostic databases is the same.

[0041] S104: If it is determined that the second part numbers in the plurality of diagnostic databases are not the same, the first part number of the target controller is read.

[0042] S105, comparing the first part number with the second part numbers in the plurality of diagnostic databases one by one, and determining whether the first part number is the same as one of the second part numbers.

[0043] Specifically, if it is determined that the second part numbers in multiple diagnostic databases are different, it means that the same target controller may correspond to different manufacturers or different production batches, and therefore correspond to different diagnostic databases. At this time, it is necessary to read the first part number of the target controller and compare the first part number with the second part numbers in multiple diagnostic databases one by one to select the corresponding matching diagnostic database.

[0044] S106: If they are the same, then the controller information preset in the diagnostic database corresponding to the second part number that is the same as the first part number is loaded locally.

[0045] Specifically, after finding the second part number that is the same as the first part number, the preset controller information in the diagnostic database corresponding to the second part number is loaded locally for subsequent diagnosis of the vehicle to be diagnosed.

[0046] The present application matches the first part number of the target controller on the vehicle to be diagnosed with the second part number in the diagnostic database, so as to quickly determine the diagnostic database that matches the target controller in the vehicle to be diagnosed from different diagnostic databases and load it to the local standby, thereby solving the technical problem that the diagnostic instrument in the prior art uses a fixed diagnostic database and a fixed configuration code to troubleshoot the vehicle and cannot meet the needs of diversified vehicle models, and achieves the technical effects of improving the automation level of the diagnostic instrument, improving the applicability of the diagnostic instrument and reducing the misoperation and misdiagnosis caused by excessive human participation of maintenance personnel, thereby effectively improving the efficiency of vehicle maintenance.

[0047] Figure 2 It is a flow chart of another control method of a diagnostic instrument provided by an embodiment of the present invention.

[0048] Alternatively, if Figure 2 As shown, the control method of the diagnostic instrument also includes:

[0049] S201: If it is determined that the number of matching diagnostic databases is equal to 1, determine whether there are multiple second part numbers in the diagnostic database.

[0050] Specifically, if it is determined that only one diagnostic database matches the target controller, it is further determined whether there are multiple second part numbers in the diagnostic database. The reason why there may be multiple second part numbers in the diagnostic database is that if the batches of the vehicles to be diagnosed are different, the same controller installed thereon may be supplied by different suppliers, and the part numbers of the same controller will also be different. At this time, it is necessary to further determine whether there are multiple second part numbers in the diagnostic database to further determine which second part number matches the target controller.

[0051] Optionally, if it is determined that there is only one second part number in the diagnostic database, indicating that the vehicle to be diagnosed of the model is only equipped with the corresponding controller, step S106 is directly executed to load the controller information preset in the diagnostic database corresponding to the second part number locally.

[0052] S202: If there are multiple second part numbers in the diagnostic database, read the first part number of the target controller.

[0053] S203: Based on the first part number, obtain the controller information preset in the matching diagnosis database and load it locally.

[0054] Specifically, if it is determined that there are multiple second part numbers in the diagnostic database, it is necessary to read the first part number of the target controller, and then match the first part number with one of the multiple second part numbers in the diagnostic database to obtain the controller information corresponding to the matching second part number.

[0055] Alternatively, if Figure 2 As shown, the control method of the diagnostic instrument also includes:

[0056] S204: If it is determined that the number of matched diagnostic databases is 0, a prompt message indicating that the diagnostic database matching fails is displayed.

[0057] S205, after displaying the prompt information, reading the next target controller in the controller data.

[0058] Specifically, if it is determined that there is no diagnostic database matching the target controller, it means that the corresponding diagnostic database is missing and there is a problem with the diagnostic instrument. At this time, a prompt message indicating that the diagnostic database match failed is displayed to remind the maintenance personnel that there is a problem with the diagnostic instrument. The next target controller in the controller data is then read, and the action of the above step S101 is continued.

[0059] On the basis of the above schemes, Figure 2 As shown, after reading the first part number of the target controller in S104, the control method of the diagnostic instrument further includes:

[0060] S206, determining whether the first part number is read successfully;

[0061] S207: If the reading is unsuccessful, multiple second part numbers are displayed, and the user is prompted to manually select the controller information of the controller corresponding to one of the second part numbers to load.

[0062] Specifically, after reading the first part number of the target controller, it is necessary to determine whether the first part number is read successfully. If not, the interface prompts the user (i.e., maintenance personnel) to manually select the controller information of a controller corresponding to one of the second part numbers to load. If the reading is successful, step S105 is executed.

[0063] On the basis of the above schemes, Figure 2 As shown, after reading the first part number of the target controller in S202, the control method of the diagnostic instrument further includes:

[0064] S208, determining whether the first part number is read successfully;

[0065] S209: If the reading is unsuccessful, a prompt message indicating that the part number reading failed is displayed.

[0066] Specifically, after reading the first part number of the target controller, it is necessary to determine whether the first part number is read successfully. If not, a prompt message indicating that the part number reading failed is displayed to prompt the maintenance personnel to read and identify the part number, and then read the next target controller in the controller data, and continue the action of the above step S101. If the reading is successful, step S203 is executed.

[0067] Alternatively, if Figure 2 As shown, the control method of the diagnostic instrument further includes: if it is determined that the second part numbers in multiple diagnostic databases are the same, then the preset controller information in all diagnostic databases is loaded locally.

[0068] Specifically, if there are multiple diagnostic databases that match the target controller, and the second part numbers carried in the multiple diagnostic databases are the same, it means that there are controllers with the same part number, but the corresponding diagnostic databases are different. For example, the vehicle to be diagnosed is equipped with multiple laser radar controllers, but the diagnostic databases corresponding to different laser radar controllers are different. At this time, the controller information preset in all diagnostic databases needs to be loaded locally for subsequent diagnosis. After the loading is completed, the next target controller in the controller data is read and the above step S101 is continued.

[0069] Alternatively, if Figure 2 As shown, the control method of the diagnostic instrument also includes:

[0070] S210: If the judgment result is that the first part number of the target controller is empty, read the next target controller in the controller data.

[0071] Specifically, if the first part number is empty, it means that the corresponding target controller is not installed on the vehicle to be diagnosed of this model, so the next target controller in the controller data is read and the action of step S101 is executed.
