Description

Technical Field

[0001] The utility model relates to the technical field of vehicle testing, in particular to a vehicle-mounted HMI automatic testing device. Background Art

[0002] With the development of new energy vehicles, the importance of test subjects related to the vehicle human-machine interface (HMI) such as function test, reliability test, response time test, fluency test, voice interaction test, etc. of the audio and video, Bluetooth, wifi, radio, car navigation, intelligent voice prompt and other modules carried by the in-vehicle infotainment system of the automobile human-machine interaction system is becoming increasingly prominent.

[0003] Existing in-vehicle HMI test equipment is customized for a single type of touch screen. Different types of touch screens have different sizes and shapes, so different test equipment is required for testing. That is, the existing in-vehicle HMI test equipment cannot adapt to all specifications of touch screens on the market.

[0004] The existing in-vehicle HMI test equipment has a single setting station and cannot test multiple touch screens at the same time. Each time the touch screen is switched, it needs to be recalibrated, which seriously affects the test efficiency.

[0005] The existing in-vehicle HMI test equipment has a single function and can only realize operations such as clicking and sliding on the screen that rely on a stylus, but cannot realize the movement of the knob. However, the knob is still an indispensable part of the in-vehicle HMI automatic test. The problem of single function also makes it impossible for the existing in-vehicle HMI equipment to realize all the test contents.

[0006] Existing in-vehicle HMI test equipment is not operator-friendly and has poor operational convenience, which affects test efficiency.

[0007] The above-mentioned problem of low efficiency of vehicle-mounted HMI test equipment has seriously affected the development efficiency of automobiles in the context of many car models and fast iterations today, resulting in uneven problems in the car computers of different cars under the same car brand. For example, the Cadillac Regal under General Motors, which has been hotly discussed in society recently, has been criticized for its car computer, which has seriously affected its sales. However, the other models under the same brand have become more stable as they are on the market for a longer time. This is caused by the different test time and test depth of different models of cars. Therefore, improving the test efficiency of vehicle-mounted HMI test equipment is the key way to solve car computer problems.

[0008] Therefore, how to provide an in-vehicle HMI automated testing device to improve the testing efficiency of the in-vehicle HMI testing device is a technical problem that needs to be solved urgently by skilled technicians. Utility Model Content

[0094] The control panel 500 is installed on the frame 100 and is located beside the first door assembly 300 for the convenience of the operator.

[0095] Combination Figure 3It can be known that the frame 100 in the present invention includes: a longitudinal beam 101 , a transverse beam 102 ; a mounting column 103 , a mounting frame 105 , a touch control execution system mounting stand 104 , a mounting panel 106 and a bottom moving assembly 107 .

[0096] The longitudinal beams 101 and the transverse beams 102 are connected in sequence and spaced apart to form a rectangular frame, and the mounting posts 103 are connected to the vertices of the rectangular frame and arranged perpendicular to the rectangular frame. Specifically, there are two groups of rectangular frames and they are arranged in parallel, and the two ends of the mounting posts 103 are respectively connected to a group of rectangular frames, and there are four mounting posts 103, thereby forming a rectangular frame.

[0097] The touch control execution system mounting stand 104 is connected to the middle of the four mounting posts 103. The shape of the touch control execution system mounting stand 104 includes but is not limited to a support plate, one side of the support plate is connected to the mounting posts 103, and the other side supports the touch control execution system 400. As long as the touch control execution system mounting stand 104 is connected to the mounting posts 103 and the touch control execution system 400 can be installed, the structure is within the protection range.

[0098] The frame 100 is divided into an upper portion and a lower portion by the touch control execution system mounting stand 104 .

[0099] The mounting frame 105 is connected to the mounting column 103 and is located below the touch control execution system mounting stand 104 . The mounting frame 105 is provided with a plug-in hole for plugging in the required equipment.

[0100] In some embodiments, a plurality of plug holes are disposed on the mounting frame 105 along the extending direction of the mounting column 103 .

[0101] The installation panel 106 is located in the middle of the lower part of the frame 100 and is used to divide the space of the lower part. The position of the installation panel 106 can be set according to different needs and is within the protection range.

[0102] The bottom moving component 107 is a roller, which is convenient for moving the vehicle-mounted HMI automated testing equipment. In some embodiments, the bottom moving component 107 is a universal wheel with a brake function.

[0103] Figure 3 The structure of the control system 800 is also shown, combined with Figure 4 It can be seen that the control system 800 includes: a domain controller 801, a board card box 802, a GPS simulator 803, a programmable power supply 804, a vehicle audio system 805, a robotic arm controller 806, a host 808, a signal generator 807 and an adjustment component 809.

[0104] The principle of setting up the components in the control system 800 in the utility model is that the complete HIL test equipment consists of a power management module, a programmable power supply, a signal conditioning power supply, an IO and communication module, a fault injection module, a controller, a real load, an external interface and the like.

[0105] During the HIL test, firstly, a real-time simulation platform is required to run the model of the controlled object, so a processor with a real-time operating system, i.e., a real-time host, is required to run the virtual vehicle in the virtual environment, i.e., the host 808 mentioned above;

[0106] Since the virtual vehicle has no real electrical interface and cannot be directly connected to the electrical interface of the controller, an IO board is required. In addition, a communication board is required to communicate with the real-time simulation platform, which is the board in the board plug-in box 802 mentioned above;

[0107] A programmable power supply is required to simulate the vehicle power supply, which is the programmable power supply 804 mentioned above;

[0108] Since the system has different electrical components and requires different power supply voltages, power modules with different output voltages are needed to supply power, and a signal conditioning power box is needed, namely the signal generator 807 and the regulating component 809 mentioned above;

[0109] Since the controlled components in the car may fail during the actual driving process, a fault injection module is needed to simulate these failure processes;

[0110] Since the HIL test equipment needs to be powered as a whole, a power management module needs to be set up;

[0111] The HIL device is a test of the controller, so a controller layout unit is required, which is the domain controller 801 mentioned above;

[0112] When some in-vehicle infotainment systems cannot be simulated in virtual reality during HIL testing, they need to be connected to a real infotainment system for testing. Therefore, a real infotainment system module is required, namely the GPS simulator 803 and the in-vehicle audio system 805 mentioned above.

[0113] External communication is required in the HIL system, so an external interface needs to be arranged.

[0114] The domain controller 801 simulates the controller of the car, the GPS simulator 803 simulates the GPS module of the car, and the car audio 805 is used to simulate the audio of the car. In addition, the domain controller 801, the board, the GPS simulator 803, and the car audio 805 are all connected to the control screen signal to be tested in the touch execution system 400.

[0115] The domain controller 801 is installed on the frame 100 through a pull-out drawer; the board card box 802 is plug-connected with the plug-in holes on the mounting frame 105 of the frame 100, and boards are arranged in the board card box 802.

[0116] The GPS simulator 803 is placed in the shielding box and plugged into the plug hole on the mounting frame 105. The GPS simulator 803 is placed in the shielding box to isolate external signal interference and ensure the accuracy of detection.

[0117] The car audio system 805 is placed in a soundproof box, and a soundproof device with a fiber structure is arranged inside the soundproof box to block the transmission of sound.

[0118] The robot controller 806 includes a robot controller box and a robot hand operator on the surface of the robot controller box, which is used to control the robot assembly 407 of the touch execution system 400 described below.

[0119] The robot controller 806 is mounted on the bottom of the frame 100 via a triangular support frame.

[0120] The control ends of the programmable power supply 804 and the signal generator 807 are both fixed on the mounting panel 106 of the frame 100 .

[0121] Combination Figure 5 and Figure 6 It can be known that the above-mentioned adjustment component 809 includes: a limiting mounting frame 8091, a flexible fixing device 8092 and a porous mounting plate 8093.

[0122] Among them, the robot controller 806 is installed on the limit mounting frame 8091, and the host 808 is pressed and fixed by the flexible fixing device 8092 and the limit mounting frame 8091. The pressing surface of the flexible fixing device 8092 is arranged with elastic material, providing a variable pressing curved surface and a high-resistance elastic stacking surface to adapt to the non-planar pressing and provide a large elastic resistance; the matching surface of the porous mounting plate 8093 is configured with long slots for adjusting and providing a pressing displacement to adapt to different sizes of pressed objects. The flexible fixing device 8092 is connected and fixed with the threaded holes arranged on the porous mounting plate 8093 by screws.

[0123] The preset test program used for testing below is stored in the storage of the host 880 and the robot arm hand controller 870, and the corresponding test program can be called for testing different test screens.

[0124] The control system 800 provides control functions including GPS simulation, audio testing, and robotic arm control.

[0125] like Figure 7As shown, the touch execution system 400 disclosed in the utility model includes: a mounting plate 401, a first screen fixing component 402, a second screen fixing component 403, a third screen fixing component 404, a screen positioning component 405, a screen pen elastic positioning component 406, a mechanical arm component 407, a first test screen 408, and a second test screen 409.

[0126] The mounting plate 401 is a multi-hole mounting plate, and has wiring holes and threaded holes arranged in a matrix array, which are used for installing the first screen fixing component 402, the second screen fixing component 403, the third screen fixing component 404, the screen positioning component 405, the screen pen elastic positioning component 406 and the mechanical arm component 407.

[0127] Evenly arranged wiring holes and threaded holes provide convenience for the layout of touch screens in various positions.

[0128] It should be noted that the first test screen 408 in this article is a universal flat-plate-shaped screen with an assembly hole at the bottom, and the positions and angles of the assembly holes of screens of different car models are different; the second test screen 409 is a screen with a curved touch surface and no assembly holes at the bottom. When this type of screen is fixed on the car, it uses its own conical tube to engage and fix with the car.

[0129] Combination Figure 8 As shown, the first screen fixing assembly 402 includes: a first base 4021 , a first lifting installation plate 4022 and a multi-hole fixing bent plate 4023 .

[0130] The first base 4021 has a waist-shaped hole extending in the horizontal direction, which is used to connect with the mounting plate 401 and adjust the position of the first base 4021 in the horizontal plane.

[0131] The first lifting installation plate 4022 has a vertical waist-shaped hole extending in the vertical direction, and the first lifting installation plate 4022 is threadedly connected to the first base 4021, and the angle of the side of the first lifting installation plate 4022 perpendicular to the first base 4021 can be adjusted, that is, the angle of the vertical waist-shaped hole of the first lifting installation plate 4022 relative to the first base 4021 can be changed. It can be understood that the first lifting installation plate 4022 is installed on the first base 4021 in a manner that it can rotate around the vertical direction.

[0132] The above-mentioned porous fixed bent plate 4023 has multiple mounting holes that penetrate the thickness direction of the porous fixed bent plate 4023, and these mounting holes are arranged along the vertical direction; the porous fixed bent plate 4023 is connected to the waist-shaped holes in the vertical direction, and the vertical position of the porous fixed bent plate 4023 is adjusted.

[0133] During the connection process between the first screen fixing component 402 and the first test screen 408, the porous fixing bent plate 4023 is threadedly connected to the first test screen 408, that is, the first test screen 408 selects the corresponding mounting holes of the porous fixing bent plate 4023 for connection to adapt to the different assembly holes of the first test screen 408, thereby improving the adaptability of the device.

[0134] Combination Fig. 9 As shown, the second screen fixing assembly 403 includes: a second base 4031 , a second lifting mounting plate 4032 and a rotatable bent plate 4033 .

[0135] Among them, the structure of the second base 4031 is the same as that of the first base 4021, the structure of the second lifting mounting plate 4032 is the same as that of the first lifting mounting plate 4022, and the connection relationship between the second base 4031 and the second lifting mounting plate 4032 is the same as the connection relationship between the first base 4021 and the first lifting mounting plate 4022, which will not be repeated here.

[0136] The rotatable bent plate 4033 is rotatably mounted in the vertical waist-shaped hole of the second lifting mounting plate 4032 , and the rotatable bent plate 4033 has a waist-shaped hole extending along its length direction.

The second screen fixing assembly 403 can adapt to the installation of the first test screen 408 with assembly holes at different angles, thereby improving the adaptability of the device.

[0138] Combination Fig.10 As shown, the third screen fixing assembly 404 includes: a first bent plate 4041 , a second bent plate 4042 , a connecting screw 4043 , a locking nut 4044 and an elastic gasket 4045 .

[0139] The first curved plate 4041 and the second curved plate 4042 are both L-shaped plates, and the openings of the first curved plate 4041 and the second curved plate 4042 are opposite to each other, and the vertical plates of the first curved plate 4041 and the second curved plate 4042 are opposite to each other and connected by a connecting screw 4043. The locking nut 4044 is threadedly connected to the connecting screw 4043, and is used to adjust the distance between the first curved plate 4041 and the second curved plate 4042, and to lock the first curved plate 4041 and the second curved plate 4042.

[0140] Elastic gaskets 4045 are provided on the vertical plates of the first curved plate 4041 and the vertical plates of the second curved plate 4042, respectively, so that the first curved plate 4041 and the second curved plate 4042 can be flexibly fitted when they are fitted. The elastic gaskets 4045 can be fixed to the first curved plate 4041 and the second curved plate 4042 respectively by bonding.

[0142] During the process of fixing the second test screen 409 using the third screen fixing assembly 404, the first bent plate 4041 and the second bent plate 4042 of the third screen fixing assembly 404 are respectively arranged on both sides of the conical tube of the second test screen 409, and the locking nut 4044 is rotated so that the first bent plate 4041 and the second bent plate 4042 clamp the conical tube, and during the clamping process, the elastic gasket 4045 forms a conical surface adapted to the conical tube to ensure the stability of the structure of the second test screen 409.

[0143] It should be noted that the number of the first screen fixing components 402 , the number of the second screen fixing components 403 , and the number of the third screen fixing components 404 are set according to the size of the test screen, which is not specifically limited here.

[0144] In the utility model, three screen fixing components are arranged, so that a plurality of different types of test screens can be tested at the same time, thus solving the problem of single test.

[0145] Combination Fig.11 As shown, the screen positioning assembly 405 includes: a screw 4051, a vertical locking device 4052 and a ball head locking device 4053.

[0146] A vertical locking device 4052 is fixed to one end of the screw rod 4051 , and a ball locking device 4053 penetrates the vertical locking device 4052 in a direction perpendicular to the extending direction of the screw rod 4051 , and the ball locking device 4053 is rotationally connected to the vertical locking device 4052 .

[0147] The screw 4051 is connected to a threaded hole on the mounting plate 401 that is close to the target positioning point of the test screen. By connecting the screw 4051 with the threaded hole of the mounting plate 401, the vertical position of the vertical locking device 4052 on the screw 4051 is adjusted, and the distance between the ball head locking device 4053 and the vertical locking device 4052 is adjusted, thereby realizing the adjustment of the horizontal position of the ball head locking device 4053.

[0148] The ball head locking device 4053 has a ball head at one end away from the vertical locking device 4052, and a threaded rod with a hexagonal hole at the other end. The ball head is inserted into the threaded rod through a thermal expansion process. When in use, the rotation position of the ball head locking device 4053 is adjusted by rotating the hexagonal wrench in the hexagonal hole.

[0149] During the process of positioning the test screen using the screen positioning assembly 405, the screw 4051 selects and connects to a threaded hole on the mounting plate 401 that is close to the target positioning point of the test screen, and adjusts the horizontal position of the ball head locking device 4053 so that the axis of the ball head locking device 4053 is close to the target positioning point; then, the nut on the vertical locking device 4052 is locked, and the thread is tightened by double nuts to prevent loosening; the ball head locking device 4053 is rotated so that the ball head contacts the target positioning point of the test screen, and finally, the nut on the ball head locking device 4053 is locked, and the thread is tightened by double nuts to prevent loosening.

[0150] The screen positioning assembly 405 is used to position the test screen. Three or more screen positioning assemblies 405 are required to cooperate in positioning the test screen. After the screen is disassembled, since the screen positioning assembly 405 does not move, it can ensure that the test screen can be quickly installed to the same position as the first installation when it is installed for the second time.

[0151] A variety of screen fixing devices and positioning devices are designed specifically based on the characteristics of current vehicle-mounted screens, further solving the problem of the program being unable to be reused due to inconsistent positions after the screen is disassembled and put back for testing.

[0208] Combination Fig.23 As shown, the utility model also discloses a vehicle-mounted HMI automatic testing method, comprising the following steps:

[0209] Step S100, preset test program:

[0210] Step S100 may include the following steps:

[0211] Step S110: positioning and fixing a plurality of test screens on the screen fixing assembly respectively, and connecting the test screens to the in-vehicle infotainment device for communication.

[0212] On the mounting plate 401 , the first screen fixing component 402 , the second screen fixing component 403 or the third screen fixing component 404 of the touch execution system 400 is selected for fixing according to the shape and structure of the screen to be tested, and the screen positioning component 405 is used to position the screen to be tested.

[0213] Step S120: compile an initial waypoint at the end of the robotic arm assembly.

[0214] The initial posture of the end of the robot arm assembly is programmed, that is, the zero position of the end of the robot arm assembly, and this waypoint is used as the initial position or initial waypoint of all execution programs of the end of the robot arm assembly.

[0215] Step S130: establishing a screen coordinate system corresponding to each test screen by taking the edge of each test screen as a reference edge.

[0216] The operator analyzes the geometric features of each screen under test, selects reference edges, and establishes the coordinate system of each screen under test based on the selected features;

[0217] Step S140: Correct the origin of each test screen coordinate system through data feedback from the touch pen and force sensor.

[0218] Use the touch screen pen 4073 to calibrate the screen under test and determine the origin. According to the feedback value of the force sensor of the robotic arm assembly, adjust the vertical coordinates of each reference point.

[0219] Specifically, after the touch pen 4073 is clicked on the screen to be tested, a point on the screen to be tested is selected as the origin, and then it is moved along the two sides of the screen to be tested to determine the X axis and the Y axis, and finally the Z axis is determined in the vertical direction of the determined XOY plane.

[0220] When the stylus pen 4073 touches the test screen, the pressure value applied by the stylus pen to the test screen is detected by the pressure sensor and fed back to the operator. The operator adjusts the distance of the stylus pen 4073 relative to the test screen according to the feedback value of the force sensor until the preset pressure value is met to prevent the stylus pen 4073 from applying excessive pressure to the test screen.

[0221] Step S150 , programming is performed based on the test screen coordinate system according to the test requirements corresponding to each test screen, so as to test the test screen.

[0222] According to the test requirements of each test screen, programming is performed based on the reference system of each test screen, and testing is performed on this basis.

[0223] Step S160: compile a plurality of preset test programs and store them in the control system.

[0224] According to the test screen to be tested and the coordinate system set for the corresponding test screen, multiple test programs can be compiled and stored in the host 880 and the manipulator hand controller 870, which is convenient for test personnel to select and call.

[0225] Step S200: Automated HMI testing:

[0226] Step S200 includes the following steps:

[0227] Step S210: Establish a one-to-one communication relationship between the program shortcut button of the control panel and the test program.

[0228] One-to-one communication is established between the multiple test programs stored in the host 880 and the robot arm hand operator 870 and the program shortcut buttons 505 of the control panel 500 respectively.

[0229] Step S220: Establish test preparation points for each preset test program.

[0230] According to the planning areas corresponding to the paths of multiple test programs, select similar points as test preparation points for each preset program;

[0231] Each test program corresponds to a test path of a test screen, and the test path includes a combination of single-click, double-click and / or sliding actions of the stylus on the top.

[0232] Among them, the position of each test screen, the specifications, shape and display interface of the test screen, the click position and sliding position to open each software are all different. Each path is determined according to the actual situation of the screen being tested and the test requirements.

[0233] The principle of planning the path is to plan based on the combination of single-click, double-click, and sliding actions that the stylus needs to perform at the required position within the established screen coordinate system. This has no requirements for the shape of the test screen and can be compared to human fingers operating the mobile phone screen.

[0234] Step S230, switching the test program, the end of the robot arm assembly decelerates and moves to a point under the currently executed test program.

[0235] It should be noted that for each test program, the path of the stylus is connected by waypoints one by one. The end of the robotic arm assembly is set to decelerate to the next waypoint before entering another program in order to avoid device vibration caused by rapid switching during program testing, thereby protecting the device and achieving buffering of the device.

[0236] Assuming that the preset program A is executed and it is necessary to switch to other preset programs during the test, the shortcut button 505 of other programs is clicked on the control panel 500. At this time, the end of the robot arm assembly slows down and moves to the next waypoint of the current program.

[0237] Step S240: The end of the robot arm assembly moves to a test preparation point for the next test procedure.

[0238] Step S250: execute a new test program.

[0239] Execute the next test procedure to test another test screen.

[0240] Step S260: Determine whether all test tasks are completed.

[0241] The operator can choose whether to complete all test programs when closing the program in the system interface. If not, continue to execute the current program and return to step S230. If yes, execute step S270 and the end of the robotic arm assembly returns to the initial waypoint, that is, returns to the initial posture.

[0242] Combination Fig.24 As shown, the utility model also includes a fault monitoring and processing system, which is a double-protection fault monitoring and processing mechanism for detecting the safety of the vehicle-mounted HMI automated test setting during the test process.

[0243] The fault monitoring and processing method of the vehicle-mounted HMI automated test setting in the utility model includes:

[0244] Step S310: setting a safety distance during movement of the end of the robotic arm assembly.

[0245] In the test program, set the safety distance parameter as backup data. The parameter unit can be mm, cm or m.

[0246] Step S320: setting a threshold of the clamping force at the end of the robotic arm assembly and a threshold of the force sensor.

[0247] Setting the threshold of the gripping force at the end of the robot assembly is to set the overload value fed back by the motor of the robot assembly itself.

[0248] The force sensor threshold is the overload value fed back by the force sensor.

[0249] Step S330, execute the test program to test the test screen.

[0250] During the test, a determination is simultaneously performed, step S340, determining whether the feedback value of the clamping force at the end of the robot arm assembly exceeds the threshold, and step S350 is simultaneously performed, determining whether the feedback value of the force sensor exceeds the threshold.

[0251] The threshold value of the clamping force at the end of the robotic arm assembly can be set according to different needs, and the threshold value of the force sensor is different from the threshold value of the clamping force at the end of the robotic arm assembly.

[0252] If one of step S340 and step S350 is no, then continue to execute step S330. If both step S340 and step S350 are yes, then execute step S360, stop the test, and the end of the robotic arm assembly retreats to the safety distance initially set by the system in the opposite direction of the force direction, and execute step S370, the robotic arm assembly moves to the initial waypoint. When the end of the robotic arm assembly returns to the initial waypoint, it returns to the initial posture, so that the operator can check the fault.

[0253] The above settings can achieve dual protection. The first protection is to set a force sensor at the end of the touch pen, and use the feedback of the force sensor as a protection method. The safety distance is the retraction distance when a collision occurs. The second protection is the fault detection of the device's own motor, which is the force feedback of the motor itself. The retraction operation is also performed when a collision occurs. If one of the two protections is triggered, both can protect the test screen.
