Description

Technical Field

[0001] This application relates to the field of vehicle screen testing technology, and more particularly to a vehicle screen touch testing device. Background Technology

[0002] With the rapid development of new energy vehicles, their functions are also gradually increasing. The applications and control functions integrated in the central control screen are diverse and complex, requiring testing of the touch function of the in-vehicle screen in new energy vehicles to ensure the reliability of vehicle functions.

[0003] In related technologies, there are two main testing schemes for central control screens. The first is bench testing under non-vehicle conditions, where the screen is placed on a test bench for interactive testing. The second is manual testing of in-vehicle screens, where a tester clicks the screen to execute test cases and record the results while the vehicle is in motion. The first testing method is limited by bench testing, failing to simulate the integrated operation of the vehicle and actual user conditions. This limits the testing process and makes it difficult to effectively identify potential human-vehicle interaction problems during vehicle operation, reducing the accuracy of in-vehicle screen touch testing. For the second testing method, as the complexity of central control screen functions increases and the number of functions requiring testing grows, the manual testing scheme suffers from low efficiency and a high error rate, further reducing the accuracy of in-vehicle screen touch testing.

Specifically, the controller is communicatively connected to the first motor assembly via the x-axis motor cable 6, and the controller is communicatively connected to the second motor assembly via the Y-axis motor cable 7.

[0058] In the embodiments of this application, Figure 2 The first horizontal bar frame above the first motor assembly 3 is the first frame. The first frame can be considered as the frame in the X-axis direction. The moving frame is set perpendicular to the first frame and can be the frame in the Y-axis direction. That is, the first motor assembly can drag the moving frame to move along the X-axis direction on the fixed frame of the vehicle screen; the second motor assembly drags the touch actuator to move along the Y-axis direction on the moving frame.

[0059] In this embodiment, the in-vehicle screen touch testing device is installed in the vehicle as follows: the in-vehicle screen touch testing device is positioned next to the steering wheel, above the target screen, and can also be used to fix the target screen. A schematic diagram of the circuit structure of the in-vehicle screen touch testing device is shown below. Figure 3 As shown, the device includes circuit board A, X-axis motor C, X-axis motor control board B, Y-axis motor E, Y-axis motor control board D, touch switch F, voice switch G, and seat H, etc. The internal structure of each unit and the connection methods between units are also shown.

It should be noted that the circuit structure shown in the figure is only one possible implementation of the in-vehicle screen touch testing device, and this application does not limit the in-vehicle screen touch testing device to only one type. Figure 3 The structure shown.

[0060] In this embodiment of the application, the first motor assembly can be an X-axis motor assembly, and the second motor assembly can be a Y-axis motor assembly.

[0061] In this embodiment, since the vehicle-mounted screen touch testing equipment can be installed in a vehicle, it can be activated while the vehicle is in motion to perform a touch test on the vehicle's screen. This allows an automated test bench to perform touch tests on the in-vehicle screen, enabling the vehicle-mounted screen touch testing process to be completed while the vehicle is in motion. Furthermore, using the vehicle-mounted screen touch testing equipment of this application replaces the traditional manual vehicle screen testing method, improving the efficiency and accuracy of vehicle-mounted screen touch testing while the vehicle is in motion.

The first synchronous belt 31 is embedded in a first groove in the first frame and engages with the first pulley 33. Since the two ends of the first synchronous belt 31 are fixed, the X-axis motor drives the first pulley 33 to rotate. The force generated by the rotation of the first pulley 33 causes the moving frame 8 to move along the synchronous belt. To keep the first synchronous belt 31 horizontal and taut, two first tensioning pulleys 34 are used to press the synchronous belt down. Another pair of first driven pulleys 35 cooperate with it to fix the moving frame 8 in the track of the vehicle screen fixing frame, so that the moving frame 8 moves in a predetermined direction.

The second motor assembly 4 adopts a similar connection and drive method as the first motor assembly 3. The touch actuator is fixed to the Y-axis moving platform (i.e., fixed in the second motor assembly) by a clamping device. The second synchronous belt 46 is embedded in the second groove of the moving frame 8, and drives the second pulley 42 through the second motor rotor 41 to move the touch actuator in the Y direction.

[0083] Optionally, the controller is further configured to execute the test process corresponding to the second test case, wherein the second test case is any one of the at least one test cases except the first test case.

[0085] Optionally, the controller is further configured to obtain the execution time and execution content of the first test case; and generate and save the test record of the first test case based on the execution time and the execution content; the execution content includes the execution process and execution result of the first test case.

[0086] It should be noted that the test record is a file in a preset format. The preset format file can be a CSV file or a file in other formats. The specific preset format can be determined according to the actual situation, and this application embodiment does not limit it.

[0087] Optionally, the in-vehicle screen touch testing device may also include an information acquisition interface;

[0088] The information acquisition interface is used to acquire the test case file; the test case file is a file in a preset format.

[0089] The controller is used to parse the test case file to obtain the at least one test case.

[0090] In this embodiment, the information acquisition interface can be a USB interface or other forms of information transmission interface. The specific information acquisition interface can be determined according to the actual situation, and this embodiment does not limit it.

[0091] In this embodiment, the test case file can be obtained from a device connected to the vehicle screen touch test device via a USB interface, or from the cloud, or through other means. The specific method of obtaining the test case file can be determined according to the actual situation, and this embodiment does not limit it.

[0092] In this embodiment, the user can compile a set of corresponding touch point position information based on the vehicle screen test cases. A mapping relationship is established between the test cases and each set of position information.

[0102] Understandably, by establishing an in-vehicle screen touch testing device, specifically by setting up a first motor assembly and a second motor assembly on a moving frame, with the first motor assembly driving the moving frame to move along the first frame of the fixed frame of the in-vehicle screen; the moving frame being perpendicular to the first frame; and the second motor assembly driving the touch actuator to move along the moving frame, it becomes possible to achieve the following: given at least one test case, the controller can move the touch actuator to the test position and execute the corresponding touch action according to the test action execution method for each test case. This eliminates the need for non-in-vehicle bench testing or manual testing, thus avoiding the high error rate of manual testing and improving the accuracy of in-vehicle screen touch testing.

[0103] This application provides a method for testing the touch sensitivity of an in-vehicle screen, which is applied to an in-vehicle screen touch sensitivity testing device. Figure 6 A flowchart of a vehicle screen touch testing method provided in this application embodiment is shown below. Figure 6 As shown, the in-vehicle screen touch test method may include:

[0104] S101. Obtain at least one test case during the vehicle screen touch test.

[0105] The vehicle screen touch testing method provided in this application embodiment is applicable to scenarios where touch testing is performed on a target screen in a vehicle.

The set of test locations can be the horizontal and vertical coordinates of that test location, and the set of test action execution methods can be the touch method and the delay during touch.

[0108] It should also be noted that touch methods include single click, double click, and drag.

[0109] S102. From the at least one test case, obtain the test location and test action execution method corresponding to the first test case.

[0110] In this embodiment of the application, after the vehicle screen touch test device obtains at least one test case during the vehicle screen touch test, it can obtain the test location and test action execution method corresponding to the first test case from the at least one test case.

[0111] It should be noted that the first test case is any one of the at least one test cases.

[0112] S103. On the target screen, at the location to be tested, perform the corresponding touch operation according to the execution method of the action to be tested, until each of the at least one test case is tested on the target screen.

[0113] In this embodiment of the application, after the vehicle screen touch test device obtains the test location and test action execution method corresponding to the first test case from the at least one test case, it can perform the corresponding touch operation on the target screen at the test location and according to the test action execution method until each test case in the at least one test case is tested on the target screen.

[0114] In this embodiment, the process of an in-vehicle screen touch testing device performing a corresponding touch operation on a target screen at the test location according to the test action execution method includes: converting the test location into pulse information; the pulse information being a first pulse corresponding to a first distance that the first motor assembly needs to move along a first direction and a second pulse corresponding to a second distance that the second motor assembly needs to move along a second direction; converting the first pulse into first motor rotation parameters; and driving the first motor assembly to move the first distance along the first direction while controlling the rotation of the first motor rotor in the first motor assembly according to the first motor rotation parameters; converting the second pulse into second motor rotation parameters; and driving the second motor assembly to move the second distance along the second direction while controlling the rotation of the second motor rotor in the second motor assembly according to the second motor rotation parameters; and triggering the touch actuator to perform a corresponding touch action on the target screen according to the test action execution method when both the first motor assembly and the second motor assembly have reached the test location.

[0115] In this embodiment of the application, after the vehicle screen touch testing device performs the corresponding touch operation at the test location on the target screen according to the test action execution method, it also obtains the execution time and execution content of the first test case; and generates and saves the test record of the first test case based on the execution time and the execution content.

[0116] It should be noted that the execution content includes the execution process and execution result of the first test case.

[0117] It should be noted that the test record is a file in a preset format. The preset format file can be a CSV file or a file in other formats. The specific preset format can be determined according to the actual situation, and this application embodiment does not limit it.

[0118] In this embodiment of the application, before the vehicle screen touch test device obtains at least one test case for vehicle screen touch testing, it also obtains a test case file; the test case file is parsed to obtain the at least one test case.

[0119] It should be noted that the test case file is a file in a preset format; the test case file is based on the initial test case and the corresponding touch point position and touch execution method.

[0120] For example, the execution steps of the in-vehicle screen touch test method are shown in steps 1-14:

[0121] Step 1: Based on the in-vehicle screen test cases, compile a set of corresponding touch point position information. Establish a mapping relationship between the test cases and each set of position information. Position information includes: t-delay information, x-axis coordinate, y-axis coordinate, and z-touch method (single click, double click, and drag). Specifically, the delay information is the time from when the controller issues an instruction to execute a test case to when the actual touch operation is performed.

[0122] Step 2: Save the test cases and their corresponding location information as a CSV file according to the testing requirements.

[0123] Step 3: Use a USB flash drive to store the files from Step 2 and connect it to the USB interface of the microcomputer (1).

[0124] Step 4: The microcomputer (1) program automatically parses the file and begins executing the test cases one by one.

[0125] Step 5: The program processes the location information corresponding to the test cases, including converting the x and y coordinates into hexadecimal pulse signals and processing t and z into action modes.
