Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicle-mounted terminals, and particularly to a test bench and a test system for a vehicle-mounted terminal. Background Art

[0002] With the intelligent development of automobiles, the functions of existing vehicle-mounted terminals have become more comprehensive, such as: multi-touch screens, multi-channel surround cameras, vehicle-mounted emergency call system (Emergency-CALL, eCall) functions, multi-channel audio systems, multi-channel microphone voice recognition functions, etc. Thus, during the use of vehicle-mounted terminals, certain functions often cannot be used, or error messages often appear during the use of vehicle-mounted terminals, resulting in a poor user experience. The main reason for the above problems in vehicle-mounted terminals is that in the prior art, when testing vehicle-mounted terminals, it is necessary to test each function of the vehicle-mounted terminal through multiple stations. When a certain station is missed during testing, it may cause errors in the corresponding missed functions of the vehicle-mounted terminal, resulting in low reliability of the vehicle-mounted terminal.

[0003] Therefore, how to improve the reliability of vehicle-mounted terminals has become an urgent problem to be solved. Summary of the Invention

[0007] In some feasible examples, the speaker plays a sound signal including a call voice when the vehicle-mounted terminal runs an emergency call system function program; the microphone collects the sound signal played by the speaker and reports the sound signal to the host computer for the host computer to obtain the test result of the vehicle-mounted emergency call system function based on the decibel value of the sound signal collected by the microphone.

[0008] In some feasible examples, the camera is used to collect environmental images when the in-vehicle terminal runs the camera function program, and report the environmental images to the host computer for the host computer to compare whether the environmental images are consistent with the standard environmental images, so as to obtain the test results of the camera function.

[0010] In some feasible examples, the screen is configured with a touch function. The screen is used to output a touch voltage to the in-vehicle terminal and the host computer in response to a click operation when the in-vehicle terminal runs the screen display function program, so that the in-vehicle terminal can adjust the screen display function program and / or the playback function program, and the host computer can compare the touch voltage with the standard voltage to obtain the test results of the screen touch function.

[0011] In some feasible examples, when the click operation corresponds to the screen backlight adjustment operation, the screen display function includes the screen backlight function; when the click operation corresponds to the volume adjustment operation, the playback function includes the volume adjustment function.

[0014] In a second aspect, the present disclosure provides a test system for an in-vehicle terminal, including a host computer and a test bench for the in-vehicle terminal according to any one of the first aspect. The host computer is connected to the in-vehicle terminal to be tested: in response to a user operation to start the test, the host computer controls the in-vehicle terminal to run at least one of an emergency call system function program, a playback function program, a camera function program, and a screen display function program; the host computer is connected to the test bench and receives the test results of the in-vehicle emergency call system function, the camera function, and the screen display and / or touch function sent by the test bench to determine the test results of the in-vehicle terminal.

[0015] In some feasible examples, the test system further includes: a test chamber for applying different environmental parameters to the in-vehicle terminal, where the environmental parameters include one or more of temperature and environmental pressure.

[0016] In this disclosure, the names of the above-mentioned host computer, test chamber, and test bench do not constitute a limitation to the devices or functional modules themselves. In actual implementation, these devices or functional modules may appear under other names. As long as the functions of each device or functional module are similar to those of this disclosure and fall within the scope of the claims of this disclosure and equivalent technologies.

[0017] These aspects or other aspects of this disclosure will be made more concise and understandable in the following description.

[0018] The technical solution provided by this disclosure has the following advantages compared with the prior art:

[0020] The drawings here are incorporated into the specification and form a part of this specification, showing embodiments consistent with this disclosure, and are used together with the specification to explain the principles of this disclosure.

[0021] To more clearly illustrate the technical solutions in the embodiments of this disclosure or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, for those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0022] Figure 1 Schematic diagram of the scenario of the test system for the in-vehicle terminal provided by the embodiments of the present disclosure. Detailed implementation manners

[0023] In order to more clearly understand the above objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments may be combined with each other.

[0024] Many specific details are set forth in the following description in order to fully understand the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all of the embodiments.

[0025] It should be noted that, in this text, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover a non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising a..." does not exclude the existence of additional identical elements in the process, method, article or device including the element.

[0026] As Figure 1 shown, the embodiments of the present disclosure provide a test bench 1 for an in-vehicle terminal, including: The test bench 1 includes a box body 10 and a microphone 101, a speaker 102, a camera 103 and a screen 104 arranged in the box body 10; the microphone 101 and the speaker 102 are connected to the in-vehicle terminal 2 to be tested; the microphone (Microphone, MIC) 101 and the speaker (Speaker, SPK) 102 are used to perform the function test of the in-vehicle emergency call system when the in-vehicle terminal 2 runs the in-vehicle emergency call system function (Emergency-CALL, e-Call) program, and perform the playback function test when the in-vehicle terminal 2 runs the playback function program; the camera 103 is used to perform the camera function test when the in-vehicle terminal 2 runs the camera function program, and the screen 104 is used to perform the screen display and / or touch function test when the in-vehicle terminal 2 runs the screen display function program; the test bench 1 reports the function test results of the in-vehicle emergency call system, the camera function test results and the screen display and / or touch function test to the host computer 3 for the host computer 3 to determine the test results of the in-vehicle terminal 2.

[0027] In some examples, since the vehicle-mounted terminal 2 is not externally connected to other devices (such as microphones, speakers, cameras, screens, etc.), when testing the vehicle-mounted terminal 2, these devices need to be connected to the vehicle-mounted terminal 2 in order to test the functions corresponding to the vehicle-mounted terminal 2. To facilitate the testing, the test system for the vehicle-mounted terminal provided by the embodiments of the present disclosure sets the devices that the vehicle-mounted terminal 2 needs to connect on the test bench 1, thereby facilitating the completion of the test of the vehicle-mounted terminal 2 and the accuracy of the reliability detection of the vehicle-mounted terminal.

[0028] In some examples, the test system of the vehicle-mounted terminal 2 can test multiple vehicle-mounted terminals 2 simultaneously. Exemplarily, as Figure 1 shown, BUT01 represents vehicle-mounted terminal 01, BUT02 represents vehicle-mounted terminal 02, etc.

[0029] In some examples, the host computer 3 summarizes the test results to obtain a test report of the vehicle-mounted terminal 2. When there are abnormal test results in the test report, at this time, the host computer can generate an abnormal prompt so that the tester can check the vehicle-mounted terminal 2 in time to avoid the problem of poor user experience caused by the quality problem of the vehicle-mounted terminal 2. When there are no abnormal test results in the test report, at this time, the host computer can generate a normal prompt.

[0030] As can be seen from the above, for the test bench of the vehicle-mounted terminal provided by the present disclosure, the user can complete the tests of the vehicle emergency call system function, playback function, camera function, and screen display function of the vehicle-mounted terminal through the test bench, without testing the vehicle-mounted terminal through multiple stations, thereby avoiding the problem of missed testing at a certain station or incorrect testing methods. When performing reliability detection on the vehicle-mounted terminal, with the same number of tests, by using the test bench of the vehicle-mounted terminal provided by the present disclosure, the number of problems of missed testing or incorrect testing methods is reduced, thereby improving the accuracy of the reliability detection of the vehicle-mounted terminal and solving the problem of how to perform reliability detection on the vehicle-mounted terminal.

[0031] In some feasible examples, the speaker 101 plays a sound signal including a call voice when the vehicle-mounted terminal 2 runs the emergency call system function program; the microphone 101 collects the sound signal played by the speaker 102 and reports the sound signal to the host computer 3 for the host computer 3 to obtain the test result of the vehicle emergency call system function based on the decibel value of the sound signal collected by the microphone 101.

[0032] In some examples, the host computer 3 pre-stores test instructions for each target function to be tested. When it is necessary to test the target function of the vehicle-mounted terminal 2, the host computer 3 will carry start test information with test instructions for testing each target function. In this way, after receiving the start test information, the vehicle-mounted terminal 2 sequentially executes corresponding actions according to the test instructions in the start test information to complete the test of the target function. For example, when the test instruction is used to test the vehicle-mounted emergency call system function of the vehicle-mounted terminal 2, at this time, the vehicle-mounted terminal 2 starts the vehicle-mounted emergency call system function based on this test instruction. During this period, the vehicle-mounted terminal 2 picks up the ambient sound in the sound insulation box 105 through the microphone in the sound insulation box 105, and the vehicle-mounted terminal 2 emits a corresponding sound signal (such as a call voice) through the speaker 102 in the sound insulation box 105. When the microphone 101 picks up the call voice emitted by the speaker 102 (such as the decibel value of the call voice emitted by the speaker 102 collected by the microphone 101 is greater than 0), it indicates that the vehicle-mounted emergency call system function of the vehicle-mounted terminal 2 is normal, that is, the test result of the vehicle-mounted emergency call system function of the vehicle-mounted terminal 2 is normal. When the microphone 101 does not pick up the call voice emitted by the speaker 102 (such as the decibel value of the call voice emitted by the speaker 102 collected by the microphone 101 is equal to 0), it indicates that the vehicle-mounted emergency call system function of the vehicle-mounted terminal 2 is abnormal, that is, the test result of the vehicle-mounted emergency call system function of the vehicle-mounted terminal 2 is abnormal.

[0033] In some examples, the vehicle-mounted terminal 2 can match the sound picked up by the microphone 101 with the pre-stored call voice to determine the similarity between the sound picked up by the microphone 101 and the pre-stored call voice. When the similarity is greater than the similarity threshold, it is determined that the microphone 101 has picked up the call voice emitted by the speaker 102.

[0034] In some examples, the vehicle-mounted terminal 2 can extract features from the sound picked up by the microphone 101 and the pre-stored call voice to obtain at least one first voice feature corresponding to the sound picked up by the microphone 101 and at least one second voice feature corresponding to the pre-stored call voice. Then, clustering is performed on the first voice feature and the second voice feature to obtain at least one clustering center. When the total number of clustering centers is the same as the total number of characters included in the call voice, it is determined that the microphone 101 has picked up the call voice emitted by the speaker 102.

[0035] In some implementable examples, the camera 103 is used to collect an environmental image when the vehicle-mounted terminal 2 runs the camera function program, and report the environmental image to the host computer 3 for the host computer 3 to compare whether the environmental image is consistent with the standard environmental image to obtain the test result of the camera function.

[0036] In some examples, the host computer 3 pre-stores test instructions for each target function to be tested. When it is necessary to test the target function of the vehicle-mounted terminal 2, the host computer 3 will carry start test information with test instructions for testing each target function. In this way, after receiving the start test information, the vehicle-mounted terminal 2 sequentially executes corresponding actions according to the test instructions in the start test information to complete the test of the target function. For example, when the test instruction is used to test the camera function of the vehicle-mounted terminal 2, at this time, the vehicle-mounted terminal 2 starts the camera 103 based on this test instruction. During this period, the vehicle-mounted terminal 2 obtains the environmental image transmitted by the camera 103 in real time. When the vehicle-mounted terminal 2 receives the environmental image transmitted by the camera 103, it indicates that the camera function of the vehicle-mounted terminal 2 is normal, that is, the test result of the camera function of the vehicle-mounted terminal 2 is normal. When the vehicle-mounted terminal 2 does not receive the environmental image transmitted by the camera 103, it indicates that the camera function of the vehicle-mounted terminal 2 is abnormal, that is, the test result of the camera function of the vehicle-mounted terminal 2 is abnormal.

[0037] In some examples, the vehicle-mounted terminal 2 can separate the foreground and background of the environmental image collected by the camera 103 to obtain a first foreground image corresponding to the environmental image collected by the camera 103. At the same time, the vehicle-mounted terminal 2 can separate the foreground and background of the pre-stored environmental image to obtain a second foreground image corresponding to the pre-stored environmental image. Then, feature extraction is performed on the first foreground image and the second foreground image to obtain at least one first image feature corresponding to the first foreground image and at least one second image feature corresponding to the second foreground image. Then, clustering is performed on the first image feature and the second image feature to obtain at least one clustering center. When the total number of clustering centers is equal to 1, it is determined that the vehicle-mounted terminal 2 has received the environmental image transmitted by the camera 103. When the total number of clustering centers is equal to 0, it is determined that the vehicle-mounted terminal 2 has not received the environmental image transmitted by the camera 103.

[0038] In some implementable examples, the screen 104 is used to display a video stream when the vehicle-mounted terminal 2 runs a screen display function program, and report the video stream to the host computer 3 for the host computer 3 to compare whether the video stream is consistent with the standard video stream to obtain the test result of the screen display function.

[0039] In some examples, the host computer 3 pre-stores test instructions for each target function to be tested. When it is necessary to test the target function of the vehicle-mounted terminal 2, the host computer 3 will carry start test information containing test instructions for testing each target function. In this way, after receiving the start test information, the vehicle-mounted terminal 2 sequentially executes corresponding actions according to the test instructions in the start test information to complete the test of the target function. For example, when the test instruction is used to test the screen display function of the vehicle-mounted terminal 2, at this time, the vehicle-mounted terminal 2 starts to transmit a video stream to the screen 104 based on this test instruction. During this period, the screen 104 displays based on the video stream transmitted by the vehicle-mounted terminal 2. At this time, the tester can determine whether the screen display function of the vehicle-mounted terminal 2 is normal by checking whether the screen 104 displays normally. When it is determined that the screen display function of the vehicle-mounted terminal 2 is normal, at this time, the host computer 3 can send information indicating that the screen display is normal to the vehicle-mounted terminal 2. After receiving the information indicating that the screen display is normal sent by the host computer 3, the vehicle-mounted terminal 2 stops transmitting the video stream to the screen 104 and determines that the screen display function of the vehicle-mounted terminal 2 is normal, that is, the test result of the screen display function of the vehicle-mounted terminal 2 is normal. When it is determined that the screen display function of the vehicle-mounted terminal 2 is abnormal, at this time, the host computer 3 can send information indicating that the screen display is abnormal to the vehicle-mounted terminal 2. After receiving the information indicating that the screen display is abnormal sent by the host computer 3, the vehicle-mounted terminal 2 stops transmitting the video stream to the screen 104 and determines that the screen display function of the vehicle-mounted terminal 2 is abnormal, that is, the test result of the screen display function of the vehicle-mounted terminal 2 is abnormal.

[0040] In some feasible examples, the screen 104 is configured with a touch function. The screen 104 is used to output a touch voltage to the vehicle-mounted terminal 2 and the host computer 3 in response to a click operation when the vehicle-mounted terminal 2 runs a screen display function program, for the vehicle-mounted terminal 2 to adjust the screen display function program and / or the playback function program, and for the host computer 3 to compare the touch voltage with a standard voltage to obtain a test result of the screen touch function.

[0041] In some feasible examples, the screen display function includes a screen touch function; the screen is used to complete the screen touch function of the vehicle-mounted terminal 2 driving the screen for touch display; among them, the screen touch function of the vehicle-mounted terminal 2 driving the screen for touch display includes: the vehicle-mounted terminal 2 controls the screen for touch display in response to a click operation of the user on the screen to complete the test of the screen touch function.

[0042] In some examples, the host computer 3 pre-stores test instructions for each target function to be tested. When it is necessary to test the target function of the in-vehicle terminal 2, the host computer 3 will carry start test information containing test instructions for testing each target function. In this way, after receiving the start test information, the in-vehicle terminal 2 sequentially executes corresponding actions according to the test instructions in the start test information to complete the test of the target function. For example, when the test instruction is used to test the screen touch function of the in-vehicle terminal 2, at this time, the in-vehicle terminal 2 starts the screen 104 to display test images (such as blue images, red images, green images, etc.) based on this test instruction. During this period, the tester can click on the screen. At this time, the in-vehicle terminal 2 responds to the click operation of the user on the screen and controls the screen for touch display (for example, in response to the click operation, the touch voltage of the screen 104 changes, and the corresponding touch effect is displayed at the position where the touch voltage of the screen 104 changes, or the function corresponding to the position where the touch voltage of the screen 104 changes is executed). In this way, the tester can determine whether the screen touch function of the in-vehicle terminal 2 is normal based on the touch display result of the screen 104. When it is determined that the screen touch function of the in-vehicle terminal 2 is normal, at this time, the host computer 3 can send information indicating that the screen touch is normal to the in-vehicle terminal 2. After receiving the information indicating that the screen touch is normal sent by the host computer 3, the in-vehicle terminal 2 turns off the screen 104 and determines that the screen touch function of the in-vehicle terminal 2 is normal, that is, the test result of the screen touch function of the in-vehicle terminal 2 is normal. When it is determined that the screen touch function of the in-vehicle terminal 2 is abnormal, at this time, the host computer 3 can send information indicating that the screen touch is abnormal to the in-vehicle terminal 2. After receiving the information indicating that the screen touch is abnormal sent by the host computer 3, the in-vehicle terminal 2 turns off the screen 104 and determines that the screen touch function of the in-vehicle terminal 2 is abnormal, that is, the test result of the screen touch function of the in-vehicle terminal 2 is abnormal.

[0043] In some examples, the host computer 3 pre-stores test instructions for each target function to be tested. When it is necessary to test the target function of the vehicle-mounted terminal 2, the host computer 3 will carry start test information with test instructions for testing each target function. In this way, after receiving the start test information, the vehicle-mounted terminal 2 sequentially executes corresponding actions according to the test instructions in the start test information to complete the test of the target function. For example, when the test instruction is used to test the screen backlight function of the vehicle-mounted terminal 2, at this time, the vehicle-mounted terminal 2 starts the screen 104 to display a test image (such as a blue image, a red image, a green image, etc.) based on the test instruction. During this period, the tester can switch the test image to determine whether the screen backlight function of the vehicle-mounted terminal 2 is normal. When it is determined that the screen backlight function of the vehicle-mounted terminal 2 is normal, at this time, the host computer 3 can send information indicating that the screen backlight is normal to the vehicle-mounted terminal 2. After receiving the information indicating that the screen backlight is normal sent by the host computer 3, the vehicle-mounted terminal 2 turns off the screen and determines that the screen backlight function of the vehicle-mounted terminal 2 is normal, that is, the test result of the screen backlight function of the vehicle-mounted terminal 2 is normal. When it is determined that the screen backlight function of the vehicle-mounted terminal 2 is abnormal, at this time, the host computer 3 can send information indicating that the screen backlight is abnormal to the vehicle-mounted terminal 2. After receiving the information indicating that the screen backlight is abnormal sent by the host computer 3, the vehicle-mounted terminal 2 turns off the screen and determines that the screen backlight function of the vehicle-mounted terminal 2 is abnormal, that is, the test result of the screen backlight function of the vehicle-mounted terminal 2 is abnormal.

[0044] In some implementable examples, when the click operation corresponds to the screen backlight adjustment operation, the screen display function includes the screen backlight function; when the click operation corresponds to the volume adjustment operation, the playback function includes the volume adjustment function.

[0045] In some examples, the host computer 3 pre-stores test instructions for each target function to be tested. When it is necessary to test the target function of the vehicle-mounted terminal 2, the host computer 3 will carry start test information with test instructions for testing each target function. In this way, after receiving the start test information, the vehicle-mounted terminal 2 sequentially executes corresponding actions according to the test instructions in the start test information to complete the test of the target function. For example, when the test instruction is used to test the volume adjustment function of the vehicle-mounted terminal 2, at this time, based on this test instruction, the vehicle-mounted terminal 2 will control the speaker to play the target audio and adjust the volume value of the speaker to the maximum. During this period, the tester can input an adjustment operation (such as an operation to reduce the volume value) to adjust the volume value of the speaker, and determine whether the volume adjustment function of the vehicle-mounted terminal 2 is normal according to the volume value of the speaker playing the target audio. When it is determined that the volume adjustment function of the vehicle-mounted terminal 2 is normal, at this time, the host computer 3 can send information indicating that the volume adjustment is normal to the vehicle-mounted terminal 2. After receiving the information indicating that the volume adjustment is normal sent by the host computer 3, the vehicle-mounted terminal 2 turns off the speaker and determines that the volume adjustment function of the vehicle-mounted terminal 2 is normal, that is, the test result of the volume adjustment function of the vehicle-mounted terminal 2 is normal. When it is determined that the volume adjustment function of the vehicle-mounted terminal 2 is abnormal, at this time, the host computer 3 can send information indicating that the volume adjustment is abnormal to the vehicle-mounted terminal 2. After receiving the information indicating that the volume adjustment is abnormal sent by the host computer 3, the vehicle-mounted terminal 2 turns off the speaker and determines that the volume adjustment function of the vehicle-mounted terminal 2 is abnormal, that is, the test result of the volume adjustment function of the vehicle-mounted terminal 2 is abnormal.

[0046] In some feasible examples, a sound insulation box 105 is provided inside the box body, and the microphone 101 and the speaker 102 are arranged inside the sound insulation box 105.

[0047] In some feasible examples, the screen bracket 106 is slidably arranged on the box body 10, and the screen 104 is arranged on the screen bracket 106 and is pulled out of or pushed into the box body 10 along with the screen bracket 106.

[0048] In some feasible examples, the box body 10 contains a power supply 107, and the power supply 107 is connected to the microphone 101, the speaker 102, the camera 103, and the screen 104.

[0049] In some feasible examples, rollers 108 are provided at the bottom of the box body 10, and the rollers 108 can drive the test bench 1 to move relative to the ground.

[0050] In some feasible examples, a wire harness hole 109 is provided on the box body 10 to communicate the inside of the test bench 1 with the outside of the test bench 1.

[0051] In some implementable examples, the interior of the test bench 1 is divided into two placement areas by a partition. One placement area houses some of the soundproof box 105, camera 103, screen 104, and power supply 106, and the other placement area houses another part of the soundproof box 105, camera 103, screen 104, and power supply 106.

[0052] In some implementable examples, the interior of the test bench 1 is divided into three placement areas by a partition, and each placement area houses at least one of the soundproof box 105, camera 103, screen 104, and power supply 106.

[0053] In some implementable examples, the interior of the test bench is divided into four placement areas by a partition, and each placement area houses any one of the soundproof box 105, camera 103, screen 104, and power supply 106.

[0054] In some implementable examples, the vehicle-mounted terminal 2 is respectively connected to the host computer 3 and the test bench 1 through a wiring harness.

[0055] The test system for the vehicle-mounted terminal provided by the embodiments of the present disclosure includes a host computer and the test bench 1 of the vehicle-mounted terminal as shown in Figure 1 The host computer 3 is connected to the vehicle-mounted terminal 2 to be tested: in response to a user operation to start the test, the host computer 3 controls the vehicle-mounted terminal 2 to run at least one of the emergency call system function program, playback function program, camera function program, and screen display function program; the host computer 3 is connected to the test bench 1 and receives the test results of the vehicle emergency call system function, camera function, and screen display and / or touch function sent by the test bench 1 to determine the test results of the vehicle-mounted terminal 2.

[0056] In some implementable examples, the test system further includes: a test chamber 4 for applying different environmental parameters to the vehicle-mounted terminal, where the environmental parameters include one or more of temperature and environmental pressure. The vehicle-mounted terminal 2 is disposed inside the test chamber 4 and the vehicle-mounted terminal 2 is connected to the test chamber 4; in response to a user operation to start the test, the host computer 3 instructs the test chamber 4 to apply different temperatures and / or different environmental pressures to the vehicle-mounted terminal 2.
