Description

Technical Field

[0001] The invention relates to the technical field of automobile body function testing, and in particular to an automatic testing method for a vehicle door handle. Background Art

[0002] With the continuous advancement of new energy vehicle technology, hidden door handles, due to their streamlined design, can significantly reduce the air resistance of vehicles when driving at high speeds, thus becoming an important innovation in the design of new energy vehicles. This door handle controls its deployment and retraction through a built-in motor and a sophisticated mechanical structure to adapt to different usage scenarios and user needs. At present, the testing of hidden door handles mainly relies on manual operation and visual inspection. Testers need to manually operate the door handles to check whether the deployment and retraction movements are smooth, and whether there are problems such as stagnation or abnormal noise. In addition, testers also need to monitor the working status of the door handles for a long time to ensure that they can work stably under various environmental conditions. However, this manual-dependent testing method has the problems of inefficiency and difficulty in long-term stress testing. At the same time, if the four door handles of the vehicle are not driven by the same controller, individual door handles may not work properly or deployment and retraction may be out of sync.

[0003] Currently, there is no corresponding CAN signal or LIN signal on the vehicle bus for the unfolded and retracted state of the door handle, making it difficult for testers to accurately determine the working state of the door handle through the signal state. This testing method lacking automated monitoring and feedback mechanisms not only increases the complexity and cost of the test, but also limits the accuracy and reliability of the test. Summary of the invention

[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] Traditional automated testing solutions mainly rely on data signal feedback from the vehicle bus (Controller Area Network, CAN) or Local Interconnect Network (LIN) to make result judgments, thus forming a closed test loop. This solution is effective in most cases because it can monitor and analyze the status of each system of the vehicle in real time. However, for certain specific functions, if these functions do not provide status feedback through bus signals, then traditional testing solutions cannot achieve effective closed-loop result judgments.

[0046] For example, in some models, the control of hidden door handles does not rely on traditional bus signals. These door handles are driven by domain controllers (Vehicle Interface Unit, VIU for short) such as VIU1, VIU2, VIU3, etc. according to the door lock instructions of the whole vehicle to realize the deployment and retraction control of the door handles. Under the unlocking command, these domain controllers will drive the four door handles to deploy so that passengers can open the door conveniently; under the locking command, the four door handles will be driven to retract to keep the appearance of the vehicle neat and safe. However, the deployment / retraction status of these door handles is not sent out through bus signals, which makes it impossible for traditional test schemes to directly monitor and judge the status of the door handles.

[0047] In addition, since the domain controllers driving the door handles may be different, this also increases the complexity of the test. In actual operation, there may be problems where individual door handles cannot be deployed or retracted normally, and these problems are difficult to detect and diagnose with traditional automated testing solutions due to the lack of bus signal feedback. Therefore, in response to this situation, new test methods and technologies need to be developed to effectively monitor and evaluate the status and performance of these hidden door handles without bus signal feedback.

[0048] Reference Figure 1 , shows a flow chart of the steps of a vehicle door handle automatic testing method provided in an embodiment of the present invention, which may specifically include the following steps:

[0049] Step 101, obtaining an unlocking instruction sent by an execution end, and performing an unlocking test on a door handle of a vehicle according to the unlocking instruction, wherein the unlocking instruction is used to control the door handle to perform an unlocking operation.

[0050] Reference Figure 2 , shows a connection diagram of a vehicle door handle automatic testing method provided in an embodiment of the present invention, the execution end is connected to the control end via a USB (Universal Serial Bus) data cable, specifically, the execution end can be a device that can be remotely operated such as a mobile phone, and the control end can be a computer or other device, the control end sends a series of test instructions to the execution end, and the execution end and the vehicle under test can also be connected via a Bluetooth signal. The Bluetooth connection does not require a physical cable, making the connection between devices more flexible and convenient, reducing the complexity of wiring and the potential risk of physical damage. At the same time, Bluetooth has good compatibility, which is convenient for the execution end to be connected to vehicles of different models. In addition to Bluetooth, WiFi (Wireless Fidelity) and other methods can also be used, and the present invention does not make specific restrictions on it.

[0051] The embodiment of the present invention also includes a signal acquisition board. The RS-485 connection between the signal acquisition board and the computer can achieve stable and reliable data transmission, which is particularly suitable for industrial environments or scenarios requiring long-distance communication. Through the RS-485 interface, the transmission of unlocking instructions and the acquisition of signal status values ​​can be effectively performed to ensure the performance and reliability of the test system.

[0052] The power supply (VCC) and ground (GND) pins of the signal acquisition board are connected to the No. 16 and No. 4 pins of the vehicle's OBD interface through the OBD (On-Board Diagnostics) line. This connection method uses the 12V DC power supply provided by the vehicle's OBD interface to power the signal acquisition board and ensure its normal operation.

[0053] The 485+ and 485- pins on the signal acquisition board are connected to the A and B ends of the USB to 485 serial cable respectively. The 485 here refers to the RS-485 communication protocol, which is a serial communication interface standard suitable for long-distance and high-speed data transmission. Through this connection, the USB port can be connected to the computer for communication between the computer and the signal acquisition board to achieve data exchange and control instruction transmission.

[0054] Each limit switch uses two wires to connect to the internal normally open contacts 3 and 4. The limit switch is an electronic switch. When it is triggered, the internal contacts will change from the normally open state to the closed state. The four limit switches are respectively connected to the digital input signal terminals X1\VCC (Voltage Common Collector), X2\VCC, X3\VCC, and X4\VCC of the signal acquisition board. These signal terminals are used to receive the state changes of the limit switches, thereby realizing the detection of the unfolding and retracting states of the door handle.

[0055] Reference Figure 3 , shows a schematic diagram of the structure of a vehicle door handle provided in an embodiment of the present invention. In order to ensure that the limit switch can accurately detect the state of the door handle, four limit switches need to be fixed next to the door handle by pasting or magnetic attraction. This ensures that when the door handle is unfolded, the swing arm of the limit switch can be triggered normally, and when the door handle is retracted, the swing arm of the limit switch can be restored to the untriggered state normally. In this way, the position and state of the door handle can be accurately monitored, thereby achieving comprehensive testing and control of the vehicle door handle function.

[0056] In an embodiment of the present invention, the door handle is controlled to perform a locking operation according to a locking instruction. After the door handle is switched to a locked state according to the locking operation, it waits for a first fixed time and obtains an unlocking instruction issued by the execution end again.

[0057] When the door handle receives the locking command, it will perform the corresponding locking operation. After the door handle switches from the unlocked state to the locked state according to the locking operation, the door handle will wait for a preset first fixed time. This time interval may be to ensure that the door handle has completely entered the locked state, or to simulate the waiting time in actual use, for example, the owner may unlock the vehicle again within a period of time after leaving the vehicle.

[0058] After waiting for the first fixed time, the door handle will again obtain the unlocking command sent by the execution end, and this unlocking command will trigger the door handle to perform the unlocking operation, that is, the door handle will be unfolded.

[0059] In an embodiment of the present invention, the door handle is controlled to perform an unlocking operation according to an unlocking instruction. After the door handle is converted to an unlocking state according to the unlocking operation, it waits for a second fixed time and obtains a locking instruction issued by the execution end again.

[0060] When the door handle receives the unlock command, it will perform the corresponding unlock operation, and the door handle will change from the locked state to the unlocked state, that is, the door handle will unfold. After the door handle changes to the unlocked state according to the unlock operation, the system will wait for a preset second fixed time. This time interval is to ensure that the door handle has completely entered the unlocked state, and it can also simulate the waiting time in actual use. For example, a passenger may lock the vehicle again some time before entering the vehicle.

[0061] After waiting for the second fixed time, the door handle will receive the locking command from the execution end again. This locking command will trigger the door handle to perform the locking operation, which usually means that the door handle will be retracted.

[0062] In this way, the embodiments of the present invention can continuously test the locking and unlocking functions of the door handle to ensure the reliability and response speed of these operations. At the same time, this continuous test cycle helps to discover potential problems, such as delays, jamming or other abnormal behaviors of the door handle during the locking or unlocking process.

[0063] Step 102 , collecting a signal state value of the vehicle after receiving an unlocking instruction, the signal state value is used to indicate an unlocking state of the door handle, and the unlocking state includes an unlocking state and a locking state.

[0064] The unlock state corresponding to the door handle is determined according to the signal state value, and the unlock state is recorded to generate a test log for the door handle.

[0065] When the signal state value is 1, the door handle is determined to be in an unlocked state, and when the signal state value is 0, the door handle is determined to be in a locked state.

[0066] During the vehicle automation test, the signal status values ​​of the vehicle after receiving the unlocking command are collected. These signal status values ​​are important data used to indicate the unlocking status of the door handle. The unlocking status mainly includes two situations: unlocking status and locking status. The unlocking status means that the door handle has been extended to allow passengers to open the door; while the locking status means that the door handle has been retracted to prevent the door from being opened without authorization.

[0067] In order to accurately determine the unlocked state corresponding to the door handle, the embodiment of the present invention analyzes the collected signal state value. When the signal state value is displayed as 1, it is determined that the door handle is currently in the unlocked state, indicating that the door handle has completed the unfolding action, so that the door handle can move freely. On the contrary, when the signal state value is displayed as 0, it is determined that the door handle is in the locked state, indicating that the door handle has completed the retracting action, so that the door handle remains in a fixed position and cannot be easily moved.

[0068] The signal corresponding to the unlocked state of the door handle collected in the embodiment of the present invention will be output to a display device or recording system. It can be a graphical user interface that displays a chart or indicator light of the real-time signal status; or a data recorder that records the change of the signal status over time. The format and method of the output signal may include digital display, analog instrument, LED (Light Emitting Diode) indicator light, sound prompt, etc., depending on the configuration of the test system and the needs of the tester.

[0069] The results of these unlocked states are recorded to generate a test log for the door handle. The test log is an important document for evaluating whether the door handle functions properly. It contains the state changes of the door handle under different operations, as well as detailed records of any abnormal behavior. By analyzing these logs, engineers and testers can identify potential problems, such as delayed response of the door handle, inconsistent operation, or complete failure, so as to make necessary adjustments and repairs to ensure the reliability and safety of the door handle in actual use.

[0070] Step 103, record the jump time of the signal state value, and calculate the unlocking time of each door handle based on the jump time. The signal state value includes an original state value and a target state value. The jump time is the time when the original state value changes to the target state value for the first time. The unlocking time includes the locking time of the door handle in the unlocked state and the unlocking time in the locked state.

[0071] In vehicle automation testing, it is necessary to record the transition time of the signal state value, which refers to the time it takes for the door handle to change from one state (original state value) to another state (target state value). The transition time is used to evaluate the response speed and operating efficiency of the door handle, as well as whether the test of the door handle is an effective test.

[0072] Signal state values ​​usually include two types: original state value and target state value. The original state value refers to the initial state of the door handle before receiving the unlock command, while the target state value refers to the state that the door handle should reach after completing the unlock operation. The transition time is the time from the original state value to the target state value for the first time. This time interval reflects the speed at which the door handle transitions from one state to another.

[0073] The unlocking time includes two aspects: the locking time when the door handle is in the unlocked state, and the unlocking time when it is in the locked state. The locking time in the unlocked state refers to the time required for the door handle to change from the unlocked state to the locked state, while the unlocking time in the locked state refers to the time required for the door handle to change from the locked state to the unlocked state.

[0074] By recording and calculating these times, detailed test data can be generated to help engineers and testers evaluate the performance of the door handle. If the unlocking time exceeds the preset standard or threshold, it may indicate that there is a response delay or other performance problem with the door handle, which requires further inspection and adjustment. This precise time measurement and analysis is key to ensuring the reliability of the vehicle door handle system and user satisfaction.

[0075] In the embodiment of the present invention, the unlocking test includes an unlocking test and a locking test.

[0076] The specific steps of the locking test in the embodiment of the present invention are as follows:

[0077] When the door handle is in the unlocked state, a locking command from the execution end is received after waiting for a second fixed time, and timing starts when the locking command is received.

[0078] The signal status value is continuously monitored during a third fixed time.

[0079] If the signal state value jumps from the original state value to the target state value within the third fixed time, the locking test for the door handle is judged to be a valid test, and the time for the door handle to jump from the original state value to the target state value is used as the locking time of the door handle in the unlocked state.

[0080] If the signal state value does not jump from the original state value to the target state value within the third fixed time, it is determined that the lock test for the door handle is a timeout test.

[0081] In the vehicle automation test, when the door handle is in the unlocked state, it will wait for a preset second fixed time. This time interval is to ensure that the door handle has been completely stabilized in the unlocked position. After the second fixed time, the door handle will receive a locking command from the execution end, which marks the start of the locking operation.

[0082] Once the locking command is received, the timing of this locking test will start immediately. In the next third fixed time, the signal state value is continuously monitored to determine whether the door handle can change from the unlocked state to the locked state as expected. This third fixed time is preset and defines the maximum allowed time for the door handle to change from unlocked to locked. If the signal state value successfully jumps from the original state value (unlocked state) to the target state value (locked state) within the third fixed time, the locking test for the door handle is determined to be a valid test. At this time, the time for the door handle to jump from the original state value to the target state value is recorded, and this time is the locking time of the door handle in the unlocked state. On the contrary, if the signal state value fails to jump from the original state value to the target state value within the third fixed time, the locking test for the door handle is determined to be a timeout test. This means that the door handle failed to complete the locking operation within the specified time as expected, and there may be a response delay or other performance problems. In this case, the test results will indicate that further inspection and adjustment are required to ensure the reliability and user satisfaction of the door handle in actual use.

[0083] For example, the second fixed time is preset to 10 seconds. When the door handle is in the unlocked state, the door handle will wait for 10 seconds to ensure that the door handle has been completely stabilized in the unlocked position. After the 10 seconds, the door handle will receive the locking command sent by the execution end, which marks the start of the locking operation.

[0084] After receiving the locking command, the door handle starts to perform the locking operation, that is, changes from the unlocked state to the locked state. And monitors the signal state value to determine whether the door handle can change from the unlocked state to the locked state as expected.

[0085] At the same time, the third fixed time is preset to 3 seconds, and the signal status value is continuously monitored in the next 3 seconds. This 3-second time is preset, which defines the maximum allowed time for the door handle to change from unlocked to locked. If the signal status value successfully jumps from the unlocked state to the locked state at 2 seconds, the lock test for the door handle is determined to be a valid test. At this time, the time for the door handle to jump from the unlocked state to the locked state is recorded, and this 2 seconds is the locking time of the door handle in the unlocked state. On the contrary, if the signal status value fails to jump from the unlocked state to the locked state within 3 seconds, the lock test for the door handle is determined to be a timeout test. This means that the door handle failed to complete the locking operation within the specified time as expected, and there may be a response delay or other performance problems.

[0086] The specific steps of the unlocking test in the embodiment of the present invention are as follows:

[0087] When the door handle is in a locked state, an unlocking command sent by the execution end is received after waiting for a first fixed time, and timing starts when the unlocking command is received.

[0088] The signal status value is continuously monitored during a third fixed time.

[0089] If the signal state value jumps from the original state value to the target state value within the third fixed time, the unlocking test for the door handle is judged to be a valid test, and the time for the door handle to jump from the original state value to the target state value is used as the unlocking time of the door handle in the locked state.

[0090] If the signal state value does not jump from the original state value to the target state value within the third fixed time, it is determined that the lock test for the door handle is a timeout test.

[0091] In vehicle automation testing, when the door handle is in the locked state, the door handle will wait for a preset first fixed time. This time interval is to ensure that the vehicle's entire vehicle network is in a dormant state. After waiting for the first fixed time, the door handle will receive the unlocking command issued by the execution end, which marks the start of the unlocking operation.

[0092] Once the unlock command is received, the timing of this unlock test will start immediately. In the next third fixed time, the signal state value will be continuously monitored to determine whether the door handle can change from the locked state to the unlocked state as expected. This third fixed time is preset, which defines the maximum allowed time for the door handle to change from locked to unlocked. If the signal state value successfully jumps from the original state value (locked state) to the target state value (unlocked state) within the third fixed time, the unlock test for the door handle is determined to be a valid test. At this time, the time for the door handle to jump from the original state value to the target state value is recorded, and this time is the unlock time of the door handle in the locked state. On the contrary, if the signal state value fails to jump from the original state value to the target state value within the third fixed time, the unlock test for the door handle is determined to be a timeout test. This means that the door handle failed to complete the unlocking operation within the specified time as expected, and there may be response delays or other performance problems.

[0093] For example, the first fixed time is preset to 3 minutes. When the door handle is in the locked state, it will wait for 3 minutes. This time interval is to ensure that the vehicle network is in a dormant state. After the 3 minutes, the door handle will receive the unlock command sent by the execution end, which marks the beginning of the unlock operation. After receiving the unlock command, the door handle starts to perform the unlock operation, that is, it changes from the locked state to the unlocked state.

[0094] The third fixed time is preset to 3 seconds. In the next 3 seconds, the signal status value is continuously monitored. This 3-second time is preset, which defines the maximum allowed time for the door handle to change from locked to unlocked. If the signal status value successfully jumps from the locked state to the unlocked state at 2 seconds, the unlocking test for the door handle is determined to be a valid test. At this time, the time for the door handle to jump from the locked state to the unlocked state is recorded, and this 2 seconds is the unlocking time of the door handle in the locked state. On the contrary, if the signal status value fails to jump from the locked state to the unlocked state within 3 seconds, the unlocking test for the door handle is determined to be a timeout test. This means that the door handle failed to complete the unlocking operation within the specified time as expected, and there may be a response delay or other performance problems.

[0095] Step 104 , comparing the unlocking times corresponding to the door handles to obtain the door handle synchronization status of the vehicle.

[0096] In vehicle automation testing, the unlocking time of each door handle is compared to evaluate the door handle synchronization status of the vehicle. The door handle synchronization status refers to the coordination and consistency of all door handles when performing the unlocking operation, which is specifically reflected in whether the unlocking time of all door handles is consistent.

[0097] After performing the unlocking test on each door handle, the embodiment of the present invention records the time for each door handle to jump from the original state value to the target state value, that is, the unlocking time. These time data are the basis for evaluating the synchronization state of the door handle.

[0098] The unlocking time of all door handles is compared, which usually involves calculating statistical indicators such as the average value, standard deviation, maximum value and minimum value of the time data, and the present invention does not make specific restrictions on this.

[0099] The synchronization state of the door handles can be evaluated by comparing the unlocking times. In one embodiment, if the unlocking times of all door handles are very close, that is, the standard deviation of the time data is small, then the synchronization state of the door handles can be considered to be good. This means that all door handles complete the unlocking operation almost at the same time, showing a high degree of coordination and consistency. On the contrary, if the unlocking times of the door handles vary greatly, that is, the standard deviation of the time data is large, then it may indicate that the synchronization state of the door handles is not good. This may mean that some door handles respond slowly or have inconsistent operations.

[0100] Based on the comparison results, a synchronization status report can be further generated. This report will list the unlocking time of each door handle in detail, as well as the overall synchronization status assessment. The report may indicate which door handles are performing well and which door handles need further inspection and adjustment. If the synchronization status report shows that there are synchronization problems with the door handles, engineers and testers will take corresponding measures. This may include adjusting the control parameters of the door handle, checking the electrical connections, replacing faulty parts, etc., to ensure that all door handles can maintain consistent operating performance in actual use.

[0101] The embodiment of the present invention obtains the unlocking instruction issued by the execution end, and performs an unlocking test on the door handle of the vehicle according to the unlocking instruction, collects the signal state value of the vehicle after receiving the unlocking instruction, records the jump time of the signal state value, and calculates the unlocking time of each door handle according to the jump time.
