[0042] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0043] Example 1

[0044] An embodiment of the present application provides a method for testing an automobile instrument system, which is used to improve the efficiency of testing an instrument system on a vehicle.

[0045] Figure 1 The flow chart of the test method of the automobile instrument system of this application is shown below. Figure 1 The test method of the automobile instrument system of the present application is described in detail:

[0046] Step S101: Based on the category of the instrument system to be tested, the test system configured in the second processor core of the multi-core processor obtains the protocol rules of the category corresponding to the instrument system from a preset protocol database, the instrument system is configured in the first processor core of the multi-core processor and runs on a first hardware set associated with the first processor core, the test system runs on a second hardware set associated with the second processor core, and the first hardware set and the second hardware set belong to different hardware domains of the multi-core processor;

[0047] In this embodiment, the instrument system of the car is configured on a processor core of the on-board multi-core processor, which runs the Linux operating system. The instrument system is mainly used to control the speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, and electronic indicator lights on the dashboard. The test system is configured on another processor core of the on-board multi-core processor, which runs the Android operating system. The system is mainly an entertainment control system for in-vehicle entertainment. In some other embodiments of the present application, the test system can also be deployed separately on a processor core. It is understandable that when performing pre-factory testing, the test protocol instructions can be sent directly to the instrument system through the operating system of the entertainment control system without using a computer and the test software on the computer.

[0048] It should be noted that after the pre-shipment test is completed and it is determined that the instrument system is error-free, the test system can be deleted from the instrument central control system or retained.

[0049] It should be noted that, in this embodiment, the category of the instrument system refers to the manufacturer category of the instrument system, and the formats of protocol commands received by instrument systems of different manufacturers are different.

[0050] For example, for an instrument system of type A, the protocol instruction consists of head, type, cmd, value, checkcode, obligate and end.

[0051] In this embodiment, the protocol database is directly configured on the Android operating system where the test system is located, and the test system manages the addition, deletion, modification and viewing of the protocol rules of each instrument system in the vehicle factory protocol database. In some other embodiments of the present application, the vehicle factory protocol database is a cloud database.

[0052] It is understandable that the protocol database is only a database used to store the protocol rules of the vehicle manufacturers to which various types of instrument systems belong. It can exist as an independent database or as a part of the test system.

[0053] Step S102: Based on the selected test item and its test input, generate a protocol instruction of the test item according to the protocol rule to the instruction sending queue;

[0054] Specifically, the test items include engine speed, fault lights and dashboard speed.

[0055] For example, if the instrument system is an instrument system of FAW Hongqi, the test item is to test the instrument panel speed, and the test input is 80, a protocol instruction for testing the instrument panel speed 80 of the instrument system of FAW Hongqi will be generated according to the above protocol rules.

[0056] It should be noted that the protocol instruction in this implementation is a controller area network protocol.

[0057] Step S103: after adjusting the order of the protocol instructions in the instruction sending queue, the protocol instructions are sent to the instrument system in order through the inter-core communication interface;

[0058] Specifically, after the tester generates multiple protocol instructions according to the test requirements, the sending order of these protocol instructions can be adjusted to test the instrument system according to the project test order of the tester.

[0059] In some implementations of the present application, the protocol instructions in the instruction sending queue can be randomly sent for testing. Specifically, based on the number of protocol instructions in the instruction sending queue, a group of random numbers of the corresponding number is generated, and then the protocol instructions corresponding to the random numbers are sent in the order of the random numbers.

[0060] For example, there are 10 protocol instructions 1, 2, 3...10 in the current instruction sending queue. When they are sent randomly, a group of unordered random numbers from 1 to 10 will be generated, such as 2, 8, 10, 1, 3, 5, 7, 6, 9, 4. The second protocol instruction will be sent first in the order of the random numbers, then the 8th protocol instruction will be sent... and finally the fourth protocol instruction will be sent.

[0061] In this embodiment, the inter-core communication interface uses a virtual network such as rpmsg to achieve communication between the two systems. In some other embodiments of the present application, the inter-core communication interface can also be implemented by Mailbox, shared memory, local socket, etc.

[0062] In this embodiment, the protocol instructions all use the CAN bus protocol, CAN is the abbreviation of Controller Area Network (CAN), and the CAN bus protocol has been widely used as a standard bus for automotive computer control systems and embedded industrial control local area networks. Step S104: The instrument system responds to the received protocol instructions and outputs the response results on the instrument panel to determine the test results.

[0063] It can be understood that when the vehicle manufacturer of the protocol format of the protocol instruction sent by the test system is consistent with the vehicle manufacturer of the instrument system to be tested, the instrument system can directly respond to the received protocol instruction.

[0064] It can be understood that if the response result on the instrument panel is consistent with the response result theoretically corresponding to the sent protocol instruction, it means that the test protocol instruction of the instrument system is tested normally.

[0065] In this embodiment, based on the selected test items and their test inputs, the step of generating the protocol instructions of the test items through the project protocol standard corresponding to each test item includes:

[0066] Initialize a protocol instruction constructor of the instrument system category according to the protocol rules;

[0067] Specifically, each type of vehicle manufacturer's instrument system corresponds to a protocol rule, and each protocol rule corresponds to a protocol instruction constructor.

[0068] The protocol instruction builder generates protocol instructions based on test items and test inputs.

[0069] In this embodiment, the test system is configured to control the display device to display a human-computer interaction interface to receive the instrument system category selection instruction, the test item selection instruction and the item test input instruction from the tester.

[0070] Specifically, the tester can select the parking lot category and test items of the instrument system to be tested in the test system by touch through the Android system where the test system is located, and input the item test input by typing.

[0071] Example 2

[0072] An embodiment of the present application provides a test system for an automobile instrument system, wherein the test system for the instrument system is located on two processor cores of a multi-core processor. Figure 2 This is a schematic diagram of the structure of the multi-core processor in which the automobile instrument system of this application is located. Figure 2 As shown, the instrument system 200 is configured on the first processor core 20 of the multi-core processor 10, and runs on a first hardware set associated with the first processor core 20; the test system 100 is configured on the second processor core 30 of the multi-core processor 10, and runs on a second hardware set associated with the second processor core 30, and the first hardware set and the second hardware set belong to different hardware domains of the multi-core processor 10.

[0073] It should be noted that the types of operating systems installed on the first processor core 20 and the second processor core 30 do not affect the implementation of this embodiment.

[0074] Configuring the test system 100 on another core of the multi-core processor 10 where the instrument system 200 is located facilitates pre-shipment testing without the use of a PC.

[0075] Figure 3 The structure diagram of the test system of the automobile instrument system of this application is as follows: Figure 3 As shown, including:

[0076] The human-computer interaction module 101 is used for the tester to select the category of the instrument system to be tested, the test items and the input item test input;

[0077] The instruction generation module 102 is connected to the human-computer interaction module 101 and is used to generate corresponding protocol instructions to the protocol instruction queue based on the user's selection and test input;

[0078] The sequence adjustment module 103 is connected to the instruction generation module 102 and is used to adjust the sending order of each protocol instruction in the protocol instruction queue;

[0079] The instruction sending module 104 is connected to the sequence adjustment module 103 and is used to send protocol instructions to the instrument system in the order of sending through the inter-core communication interface for the instrument system to respond and observe the response result; in this embodiment, the inter-core communication interface uses a virtual network such as rpmsg to realize communication between the two systems. In some other embodiments of the present application, the inter-core communication interface can also be implemented by Mailbox, shared memory, local socket, etc.

[0080] In this embodiment, when generating protocol instructions, the instruction generation module 102 first creates a protocol instruction constructor 1021 of the corresponding category based on the category of the instrument system selected by the tester. The protocol instruction constructor 1021 is used to generate protocol instructions for testing according to the test items and test inputs in accordance with the protocol rules of the category of the selected instrument system 200.

[0081] It is understandable that the protocol rules of various categories of instrument systems are stored in a database, and testers can manage the addition, deletion, modification and query of the protocol rules in the database.

[0082] It is understandable that in order to adapt to various transmission frequencies, the instruction transmission module 104 is configured to be able to set the transmission frequency. It should be noted that in this embodiment, the category of the instrument system refers to the manufacturer category of the instrument system, and the formats of protocol instructions received by instrument systems of different manufacturers are different.

[0083] For example, for an instrument system of type A, the protocol instruction consists of head, type, cmd, value, checkcode, obligate and end.

[0084] In this embodiment, the protocol instruction constructor 1021 generates the Can protocol instruction by finding the value of the protocol field from the protocol database in the form of (type, value) and the test item and input item test input inputted by the user.

[0085] In this embodiment, the instruction sending module 104 is a service module, which has a queue for storing Can protocol instructions. The service module has a thread for sending the protocol instructions in the queue to the instrument system 200.

[0086] The working process of this system is as follows: according to the category of the instrument system 200 to be tested, the tester selects the category of the instrument system to be tested, the test items and the input of the test items through the human-computer interaction module 101; the instruction generation module 102 generates a Can test protocol instruction for testing the test item in the protocol format corresponding to the category of the instrument system 200 to the instruction sending queue according to the category of the instrument system 200, the test items and the input of the test items selected by the tester. When the tester has selected several items to be tested, the sending order of each protocol instruction in the instruction sending queue can be adjusted through the sequence adjustment module 103. After adjusting the sending order, the instruction sending module 104 sends the protocol instruction to the instrument system 200 through the virtual network method of rpmsg, determines whether the actual response result of the instrument system 200 is consistent with the expected response result of the protocol instruction, and completes the test.

[0087] It should be noted that when designing the test system, the present embodiment also designs an instrument system for testing the test system. Figure 4 The principle framework diagram of the instrument system of this application is as follows: Figure 4 As shown, the instrument system includes an interconnected parsing module 51 and a service management module 52, wherein the parsing module 51 is used to create a parser 54 or a basic parser 53 matching the received protocol instruction to parse the protocol instruction based on the received protocol instruction, and the service management module 52 is used to initialize, register, unregister and publish a callback interface 55, and the callback interface 55 is used for the parsed protocol instruction to call the corresponding interface function to respond to the protocol instruction. The interface function is implemented through the UI and is mainly used to update the UI status display or play a warning sound prompt, such as updating the speed and updating the engine information. The service management module 52 is also used to manage the process service module 56, and the process service module 56 is used to start the process of responding to the Can protocol instruction.
