Description

Technical Field

[0001] The present disclosure relates to the field of automobile testing technology, and in particular to a vehicle computer function testing system. Background Art

[0002] With the rapid development of automobile technology, the functions that can be carried by the vehicle computer system are gradually increasing, meeting people's needs for entertainment and communication functions while driving. In order to ensure the yield rate of the car, the various functions of the vehicle computer system must be tested during the research and development stage and the standard operating procedure stage to see whether they can operate normally.

[0003] For the test method of vehicle computer functions, in addition to the traditional manual operation method, the machine can also be used to complete the automated test process. During the automated test process, the robot arm is mainly used to replace the test engineer to complete the corresponding operation of the vehicle, thereby reducing the possibility of operational errors and omissions due to limited human energy and physical strength, and at the same time speeding up the test time and improving the test efficiency.

[0004] However, there are still some problems when using the above method to test certain functions of the vehicle system. For example, when testing the switch function of the vehicle system, in the functional test stage, the test system controls the mechanical arm to press the switch on the vehicle body to detect whether the vehicle system can complete the opening and closing of the corresponding function according to the instruction. Since the number of tests is small in the functional test stage, the detection effect of the mechanical arm is good; but in the pressure function test stage, it is necessary to control the mechanical arm to press the switch multiple times and perform thousands of repeated tests. Because the mechanical arm takes a certain amount of time to perform the action, it will increase the duration of the test process and reduce the test efficiency; and the switch on the vehicle body will be lost after multiple pressings, and the consistency of the test cannot be guaranteed, which reduces the test quality; when the corresponding function of the vehicle is not turned on or off normally after pressing the switch, it means that the test result is unqualified, but at this time it cannot be determined whether there is a problem with the physical switch on the vehicle body or the vehicle system inside the vehicle, so it is necessary to test each part separately, which increases the difficulty of analysis and reduces the test efficiency.

[0005] For example, when testing the charging function of the vehicle system, the above problems will also occur. In the stress test stage, multiple passes are required, so there will also be problems such as long test time, difficulty in result analysis, and low test efficiency and quality. Moreover, in this traditional automated testing process, a large number of robotic arms are required to complete the corresponding operations on the vehicle, which will increase the difficulty of designing the test system and also increase the cost of the testing process.

[0051] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0052] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0053] At present, when conducting functional tests on the vehicle's on-board system, although machine testing methods have replaced manual operations and realized automated testing processes, during the stress function testing stage that needs to be repeated many times, it is necessary to control the robotic arm to directly operate the hardware parts of the vehicle body to be tested. For example, when testing the switch function of the vehicle's on-board system, it is necessary to control the robotic arm through the test system to press the switch on the body; when testing the charging function of the vehicle system, it is necessary to control the robotic arm through the test system to insert the charging plug into the charging port of the vehicle body.

[0054] With the rapid development of the automotive technology field, this traditional automated testing method can no longer meet the needs of testing. Because when performing pressure function testing, the traditional automated testing method takes a certain amount of time to execute each step of the action in the process of controlling the robotic arm, which prolongs the overall pressure function test time and reduces the test efficiency; and the body hardware has loss problems, and the consistency of the test cannot be guaranteed, which reduces the test quality; because it is necessary to send signals to the vehicle system through the body hardware, when there is a problem with the test results, it will increase the difficulty of analysis and reduce the test efficiency. In addition, in the traditional automated testing process, a large number of robotic arms are required to complete the corresponding operations on the vehicle, which will increase the difficulty of designing the test system and also increase the cost of the testing process.

[0055] The disclosed embodiment proposes a vehicle computer function test system, which can directly control and detect the vehicle computer system to be tested, thereby shortening the test time, reducing the analysis difficulty, and improving the test efficiency; ensuring the test consistency, improving the test quality and reducing the cost.

[0056] Figure 1 FIG. 1 is a schematic diagram of a vehicle function test system according to an embodiment of the present disclosure. Figure 1 As shown, a vehicle function test system provided by an embodiment of the present disclosure includes: a signal simulation circuit board 101 and an output monitoring device 102 .

[0057] The signal simulation circuit board 101 is used to output a simulated input signal. The simulated input signal simulates the input signal generated when the vehicle hardware to be tested is triggered. The simulated input signal is used to test the vehicle system 103 to be tested.

[0058] The output monitoring device 102 is used to receive the control signal generated when the vehicle system 103 to be tested processes the analog input signal.

[0059] The vehicle computer function test system proposed in the present application directly sends a simulated input signal to the vehicle computer system to be tested through a signal simulation circuit board to simulate the corresponding input signal generated by the vehicle computer system when the hardware of the vehicle to be tested is triggered; and the output monitoring device receives the control signal generated when the vehicle computer system to be tested processes the simulated input signal to complete the test of the corresponding function of the vehicle computer system. The vehicle computer function test system proposed in the present application includes a control host computer, which is used to control the signal simulation circuit to output the simulated input signal.

[0060] Therefore, the vehicle function test system provided by the present application can shorten the duration of the test process and improve the test efficiency because it directly controls the vehicle system to be tested through a signal simulation circuit board; the solution provided by the present application realizes the control of the vehicle system to be tested by means of analog signals, and there is no problem of vehicle body hardware loss during the test process, thereby ensuring the test consistency and improving the test quality; the solution provided by the present application can more accurately detect the problem, reduce the difficulty of analysis and improve the test efficiency because it directly controls and detects the vehicle system to be tested; and the solution provided by the present application reduces the number of robotic arms during the test and reduces the cost of the automated testing process.

Figure 2 As shown, the second vehicle function test system provided by the embodiment of the present disclosure includes: a signal simulation circuit board 201, an output monitoring device 202 and a data analysis device 204.

[0062] The signal simulation circuit board 201 is used to output a simulated input signal. The simulated input signal simulates the input signal generated when the vehicle hardware to be tested is triggered. The simulated input signal is used to test the vehicle system 203 to be tested.

[0063] The output monitoring device 202 is used to receive the control signal generated when the vehicle system 203 to be tested processes the analog input signal.

[0064] The data analysis device 204 can receive the analog input signal output by the signal simulation circuit board 201 and the control signal received by the output monitoring device 202 in real time, so as to determine whether the function of the vehicle system 203 to be tested is normal according to the analog input signal and the control signal.

[0065] The vehicle function test provided by the present application includes a data analysis device, which is used to detect whether the vehicle system to be tested can generate corresponding control signals according to the instructions of the analog input signal. The data analysis device determines whether the function of the vehicle system to be tested is normal based on the analog input signal output by the signal simulation circuit board and the control signal when the vehicle system to be tested processes the analog input signal. Therefore, the test results of the vehicle function test system can be made more accurate, and the test quality is improved.

[0066] Figure 3 FIG. 1 is a schematic diagram of a third vehicle function test system according to an embodiment of the present disclosure. Figure 3 As shown, the third vehicle function test system provided by the embodiment of the present disclosure includes: a signal simulation circuit board 301, an output monitoring device 302 and a data analysis device 304.

[0067] The signal simulation circuit board 301 is used to output a simulated input signal. The simulated input signal simulates the input signal generated when the vehicle hardware to be tested is triggered. The simulated input signal is used to test the vehicle system 303 to be tested.

[0068] The output monitoring device 302 is used to receive the control signal generated when the vehicle system 303 to be tested processes the analog input signal.

[0069] The storage device 304 can receive the analog input signal output by the signal simulation circuit board 301 and the control signal received by the output monitoring device 302 in real time, and store the received analog input signal output by the signal simulation circuit board 301 and the control signal received by the output monitoring device 202.

[0070] The vehicle function test provided by the present application includes a storage device, which can receive and store the analog input signal output by the signal simulation circuit board and the control signal received by the output monitoring device, so that the test structure of the vehicle function test can be stored, which is convenient for subsequent data analysis and increases the test efficiency.

[0071] Figure 4 FIG. 4 is a schematic diagram of the fourth vehicle function test system according to the embodiment of the present disclosure. Figure 4 As shown, the fourth vehicle function test system provided by the embodiment of the present disclosure includes: a switch signal simulation circuit 401 and an output monitoring device 402.

[0072] The switch signal simulation circuit 401 is used to output a switch input signal generated when a simulated vehicle physical switch is triggered, and transmit the switch input signal to the vehicle system to be tested 403, so as to perform a switch function test on the vehicle system to be tested 403.

[0073] The output monitoring device 402 is used to receive a switch control signal generated when the vehicle system 403 to be tested processes a switch input signal.

[0074] The vehicle computer function test provided in the present application includes a switch signal simulation circuit, which enables remote control of the opening and closing of the vehicle switch without touching the physical switch of the vehicle, thereby achieving the effect of using analog signals to control the switch function of the vehicle computer system under test.

[0075] When the in-vehicle infotainment (IVI) system function test system provided in this application conducts a switch function test, it does not need to control a robotic arm to press the physical switch on the vehicle body. Instead, it directly sends a simulated signal to the IVI system under test through a switch signal simulation circuit to simulate the control process of the IVI system under test when the physical switch on the vehicle body is pressed, so as to complete the switch function test of the IVI system under test. Therefore, when conducting a pressure test, the IVI system function test system provided in this application can speed up the switch function test, shorten the duration of the test process, and improve the test efficiency; since a switch signal simulation circuit is used to directly send a simulated switch signal to the IVI system under test, there is no need to consider the wear condition of the physical switch on the vehicle body, which ensures the test consistency and improves the test quality; if a problem is found in the test result, it can be directly determined that the problem lies within the IVI system under test, and then the IVI system under test is inspected and repaired without considering whether other factors affect the test process, reducing the analysis difficulty and improving the test efficiency on the premise of controlling costs. In the IVI system function test system provided in this application, a hardwired board can also be used to output a simulated switch signal to complete the switch function test of the IVI system under test.

[0076] Figure 5 Schematic diagram of the fifth IVI system function test system described in the embodiments of the present disclosure. As Figure 5 shown, the fifth IVI system function test system provided in the embodiments of the present disclosure includes: a switch signal simulation circuit 501, a physical switch 502, a programmable three-way valve 503, and an output monitoring device 505.

[0077] The switch signal simulation circuit 501 is used to output a switch input signal generated when the physical switch of the vehicle is triggered, and transmit the switch input signal to the IVI system under test 504, so as to conduct a switch function test on the IVI system under test 504.

[0078] The physical switch 502 is used to generate a switch control signal when it is operated.

[0079] The first input end of the programmable three-way valve 503 is connected to the switch signal simulation circuit 501, the second input end of the programmable three-way valve 503 is connected to the physical switch 502, and the output end of the programmable three-way valve is used to be connected to the IVI system under test 504; the programmable three-way valve 503 is used to realize the switching between the switch signal simulation circuit 501 controlling the IVI system under test 504 and the physical switch 502 controlling the IVI system under test 504.

[0080] The output monitoring device 502 is used to receive the switch control signal generated when the IVI system under test 503 processes the switch input signal or the switch control signal.

[0081] The in-vehicle infotainment (IVI) system function test system provided by this application realizes the switching function between the analog switch and the physical switch by adding a programmable three-way valve. The programmable three-way valve adopts the principle of a single-pole double-throw switch. The two fixed terminals of the programmable three-way valve are respectively connected to the switch signal simulation circuit and the physical switch of the vehicle to be tested, and the moving terminal of the programmable three-way valve is connected to the IVI system to be tested. When controlling the programmable three-way valve to conduct the physical switch of the vehicle to be tested and the IVI system to be tested, the corresponding function needs to be turned on or off through the physical switch on the vehicle; when controlling the programmable three-way valve to conduct the switch signal simulation circuit and the IVI system to be tested, the corresponding function can no longer be turned on or off through the physical switch on the vehicle, but an analog switch signal is output to the IVI system to be tested through the switch signal simulation circuit to turn on or off the corresponding function of the vehicle to be tested.

[0082] Therefore, the IVI system function test system provided by this application can, during the function test phase, conduct the physical switch of the vehicle to be tested and the IVI system to be tested through the programmable three-way valve, and use the test system to control the robotic arm to press the physical switch on the vehicle body. Since the number of tests is small during the function test phase, the detection effect using the robotic arm is good; when in the pressure function test phase, due to the need to conduct thousands of repeated tests on the switch function, there are problems such as long test time, low test efficiency and quality. Therefore, the switch signal simulation circuit and the IVI system to be tested are conducted through the programmable three-way valve, and an analog switch signal is output from the switch signal simulation circuit to the IVI system to be tested to conduct the switch function test on the IVI system to be tested, so that during the pressure function test phase, the test time can be shortened, the test consistency can be guaranteed, the test quality can be improved, and when the test result is unqualified, the problem can be directly determined on the IVI system to be tested, reducing the analysis difficulty. Moreover, when switching between the function test phase and the pressure function test phase, using the programmable three-way valve facilitates the switching between the analog switch and the physical switch, further accelerating the test process and improving the test efficiency.

[0083] Figure 6 It is a schematic diagram of the sixth IVI system function test system described in the embodiments of the present disclosure. As Figure 6 shown, the sixth IVI system function test system provided by the embodiments of the present disclosure includes: a charging simulation circuit 601 and an output monitoring device 602.

[0084] The charging simulation circuit 601 is used to simulate the charging input signal generated when the charging interface is triggered, and output the charging input signal to the IVI system 603 to be tested for testing the charging function of the IVI system 603 to be tested.

[0085] The output monitoring device 602 is used to receive the charging control signal generated when the IVI system 603 to be tested processes the charging input signal.

[0086] The vehicle function test system proposed in the present application includes a charging simulation circuit, which realizes the effect of controlling the vehicle system under test to output a corresponding charging control signal by sending a charging input signal to the vehicle system under test. The vehicle function test system provided in the present application can also use a charging control board to output a charging input signal to complete the charging function test of the vehicle system under test.

[0087] The vehicle function test system proposed in the present application does not need to control the mechanical arm through the test system to insert the charging plug into the charging port of the vehicle body multiple times during the stress test phase of the charging function, and directly controls the charging simulation circuit to send a charging input signal to the vehicle system to be tested; or in order to simulate the situation where the charging plug is plugged into the charging port of the vehicle body, the test system can control the mechanical arm to insert the charging plug into the charging port of the vehicle body without unplugging it in the middle. During the test, the charging simulation circuit sends a charging input signal to the vehicle system to be tested. When the stress test is over, the test system controls the mechanical arm to unplug the charging plug from the charging port of the vehicle body. Therefore, there is no need to control the mechanical arm to insert and unplug the charging plug at the charging port of the vehicle body multiple times, which shortens the test time, ensures the consistency of the test, and improves the test quality; when an unqualified test result occurs, there is no need to consider the loss problem of the charging port of the vehicle body, and the problem can be directly locked in the vehicle system to be tested, thereby reducing the difficulty of analysis and improving the test efficiency.

[0090] The output monitoring device 702 is used to receive the network communication control signal generated when the vehicle system 703 to be tested processes the network communication signal.

[0091] The vehicle function test system proposed in the present application includes a communication simulation circuit, which realizes the effect of controlling the vehicle system under test to output a corresponding network communication control signal by sending a network communication signal to the vehicle system under test. The vehicle function test system provided in the present application can also use a bus communication board to output a network communication signal to complete the network communication function test of the vehicle system under test.

[0092] The communication networks that can be detected by the communication simulation circuit in the vehicle function test system proposed in this application include: controller area network (CAN), local interconnect network (LIN) and Ethernet. The communication simulation circuit is connected to the vehicle system to be tested to detect whether the functions of the controller area network bus, local interconnect network bus and Ethernet bus are normal, and verify the use of the vehicle communication network function.

[0093] In the disclosed embodiment, an entertainment domain test device is also included. The entertainment domain test device is used to test the entertainment domain function of the vehicle system to be tested; at this time, the host computer system is used to control the working state of the entertainment domain test device. The entertainment domain test device will be described in detail below.

[0094] In some embodiments, the entertainment domain testing device includes a first subordinate control device, a manipulator, and a camera.
