Description

Technical Field

[0001] This invention relates to the field of vehicle infotainment product technology, and in particular to an automatic detection method, system and device for vehicle infotainment Bluetooth connectivity compatibility. Background Technology

[0002] Existing Bluetooth connectivity compatibility testing for in-vehicle systems requires verification of compatibility with different mobile phones. Bluetooth connection requires multi-party collaboration between the in-vehicle system and the mobile phones, with different phones employing different operating methods. After successful connection, a series of compatibility operations must be performed on the in-vehicle system and multiple mobile phones, such as making and ending calls using different operating methods. If all of the above tests are conducted manually, it is impossible to perform long-term, repeated testing and evaluation. Therefore, this solution provides an automated method, system, and device for detecting Bluetooth connectivity compatibility in in-vehicle systems. Summary of the Invention

[0003] The purpose of this invention is to solve the problem that manual testing of in-vehicle Bluetooth connectivity compatibility cannot perform prolonged and repeated testing and evaluation. The specific solution is as follows:

[0004] An automatic detection method for Bluetooth connectivity compatibility in vehicles includes connecting a mobile terminal and the vehicle's infotainment system to a computer, and further includes:

[0005] Determine the type of mobile terminal to be connected;

[0006] Based on the type of the mobile terminal to be connected, select the corresponding preset method to perform Bluetooth connection operation between the mobile terminal to be connected and the vehicle system;

[0007] Obtain first target information for Bluetooth connection operation between the mobile terminal to be connected and the vehicle system;

[0008] The Bluetooth connectivity compatibility of the vehicle system is determined based on the first target information.

[0009] Furthermore, the vehicle infotainment system is based on Android. The step of selecting a corresponding preset method based on the type of the mobile terminal to be connected, and performing Bluetooth connection between the mobile terminal to be connected and the vehicle infotainment system, includes:

[0010] When the mobile terminal is an Android phone, the Android phone or the vehicle's infotainment system connects to the computer via ADB. The preset method is to use ADB to command the control unit on the computer to make the Android phone perform Bluetooth broadcasting or other operations, or for the control unit to take screenshots or perform other operations on the vehicle's infotainment system.

[0011] When the mobile terminal is an Apple phone, the preset method is that the control unit on the computer uses a coordinate positioning unit and a robotic arm to make the Apple phone perform Bluetooth broadcasting, or the control unit takes a picture of the Apple phone with a high-definition camera, or the control unit performs operations on the Apple phone with a robotic arm.

[0012] Furthermore, the first target information for obtaining the Bluetooth connection operation between the mobile terminal to be connected and the vehicle system includes: Bluetooth broadcasting, Bluetooth pairing and connection testing, making and receiving calls, hanging up calls, and deleting the status information on the respective screens of the mobile terminal and the vehicle system during the Bluetooth test process.

[0013] Furthermore, determining the Bluetooth connectivity compatibility of the vehicle system based on the first target information includes:

[0014] The computer-side visual algorithm unit judges the screenshot to see if the Bluetooth device appears in the search box: if it does, the pixel coordinates of the Bluetooth device's name are sent to the vehicle system in a preset manner to perform Bluetooth pairing; if not, the current position information of the vehicle system's search box is read to determine the priority swiping direction to find the Bluetooth device; if the Bluetooth device is still not found, the vehicle system is judged as failing the test.

[0015] Furthermore, the method for identifying the pixel coordinates of the Bluetooth device name is as follows: by using a visual algorithm unit and a coordinate positioning unit, the image information and coordinate information pre-stored in the storage unit are called, and the coordinates are determined through an algorithm and coordinate transformation method.

[0016] Furthermore, determining the Bluetooth connectivity compatibility of the vehicle system based on the first target information also includes:

[0017] The pairing process is initiated by the vehicle's infotainment system. The control unit captures a screenshot of the verification code pop-up on the vehicle's infotainment system. The vision algorithm unit judges the verification code pop-up, the coordinate positioning unit determines the coordinates of the sending box, and the vehicle's infotainment system clicks the sending box and waits for a response. The control unit takes a screenshot or photo of the mobile terminal, and the vision algorithm unit judges the screenshot or photo: if the verification code information is correct, the vehicle's infotainment system clicks the agree box; if the verification code information is incorrect or the verification code information is not received from the mobile terminal, the vehicle's infotainment system is judged as failing the test. When the vehicle's infotainment system receives a response from the other party, the vehicle's infotainment system clicks the confirmation box to start the Bluetooth connection.

[0018] Furthermore, determining the Bluetooth connectivity compatibility of the vehicle system based on the first target information also includes:

[0019] The control unit displays the phone call interface on the vehicle's infotainment system and takes a screenshot. It then determines the coordinates of the dial pad using a visual algorithm unit and a coordinate positioning unit, dials a number on the second Android phone, and waits for the other party's response.

[0020] The control unit takes a screenshot of the second Android phone, uses a visual algorithm unit to determine whether the incoming call pop-up information is correct, and a coordinate positioning unit to determine the coordinates of the answer box, and then performs the answer operation; if the incoming call pop-up information is incorrect, the vehicle system test is deemed unqualified.

[0021] The control unit takes a screenshot of the vehicle's call interface, determines the coordinates of the hang-up call frame through the visual algorithm unit and the coordinate positioning unit, and then hangs up the call.

[0022] The control unit takes a screenshot of the second Android phone and uses a visual algorithm unit to determine whether the call has ended and whether the screen has returned to the standby screen. If not, the vehicle system test is deemed unqualified.

[0023] The control unit performs a phone call operation between the second Android phone and the vehicle's infotainment system.

[0024] The control unit takes a screenshot of the vehicle's infotainment system and uses a visual algorithm unit to determine whether the incoming call pop-up information is correct and then answers the call. If the incoming call pop-up information is incorrect or there is no incoming call pop-up information, the vehicle's infotainment system is deemed to have failed the test.

[0025] The control unit takes a screenshot of the vehicle's infotainment system and uses a visual algorithm unit to determine whether the system has switched to a call interface. If it has, the system hangs up the call; otherwise, the system fails the test.

[0026] The control unit takes a screenshot of the vehicle's infotainment system and uses a visual algorithm unit to determine whether the call has ended or whether the screen has returned to the standby interface. If not, the infotainment system is deemed to have failed the test.

[0027] Furthermore, determining the Bluetooth connectivity compatibility of the vehicle system based on the first target information also includes:

[0028] The control unit brings up the Bluetooth settings menu on the vehicle's infotainment system, finds the name of the Bluetooth device to be deleted in the Bluetooth list, analyzes and judges it through the visual algorithm unit, provides the coordinates of the deletion box through the coordinate positioning unit, and clicks the deletion box on the vehicle's infotainment system.

[0029] The control unit retrieves the Bluetooth device list of the Android phone corresponding to the deleted Bluetooth device and takes a screenshot of all of them; or the control unit and the robotic arm retrieve the Bluetooth device list of the Apple phone corresponding to the deleted Bluetooth device and take a screenshot of all of them with a high-definition camera. Then, the visual algorithm unit determines whether the name of the corresponding vehicle system's Bluetooth device has been deleted from the screenshot or the screenshot. If this step is abnormal, the vehicle system test is deemed unqualified.

[0030] The control unit then retrieves the Bluetooth device list from the vehicle's infotainment system and takes screenshots of all of them. The visual algorithm unit then determines whether the names of the corresponding Android or Apple mobile phone Bluetooth devices have been deleted from all the screenshots. If not, the vehicle's infotainment system is deemed to have failed the test.

[0031] An automatic detection system for vehicle-mounted Bluetooth connectivity compatibility, used to perform the aforementioned automatic detection method for vehicle-mounted Bluetooth connectivity compatibility, includes a computer, a vehicle-mounted device electrically connected to the computer, a mobile terminal, a robotic arm, and a high-definition camera. The computer includes a control unit, a visual algorithm unit, a coordinate positioning unit, a storage unit, and an execution unit electrically connected to the control unit. The mobile terminal includes multiple mobile phones electrically connected to the control unit. The vehicle-mounted device is the vehicle-mounted device being tested, and it is electrically connected to the control unit. The mobile phones include multiple Android phones and multiple Apple phones.

[0032] An automatic detection device for vehicle-mounted Bluetooth connection compatibility, used to perform the above-mentioned automatic detection method for vehicle-mounted Bluetooth connection compatibility, includes a computer, a vehicle-mounted device electrically connected to the computer, a mobile phone, a robotic arm, and a high-definition camera. The mobile phone includes multiple Android phones and multiple Apple phones, which are placed on a multi-layered phone holder.

[0033] In summary, the technical solution of the present invention has the following beneficial effects:

[0034] This invention solves the problem that manual testing of vehicle Bluetooth connectivity compatibility cannot perform long-term, repetitive testing and judgment. Based on LabVIEW's control of a robotic arm and ADB commands, this invention overcomes the instability, fatigue, and low efficiency of manual operation.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] An automatic detection method for Bluetooth connectivity compatibility in vehicles includes connecting a mobile terminal and the vehicle's infotainment system to a computer, and further includes:

[0041] (1) Determine the type of the mobile terminal to be connected;

[0042] (2) Select the corresponding preset method according to the type of mobile terminal to be connected, and perform Bluetooth connection operation between the mobile terminal to be connected and the vehicle system;

[0043] (3) Obtain the first target information for Bluetooth connection between the mobile terminal to be connected and the vehicle system;

[0044] (4) Determine the Bluetooth connectivity compatibility of the vehicle system based on the first target information.

[0045] Specifically, the in-vehicle infotainment system runs on Android. Based on the type of mobile device to be connected, the corresponding preset method is selected. The Bluetooth connection operation between the mobile device and the in-vehicle infotainment system includes:

[0046] When the mobile terminal is an Android phone, the Android phone or the vehicle's infotainment system connects to the computer via ADB (ADB stands for Android Debug Bridge, a command-line tool that allows emulators or connected Android devices to communicate, and it can facilitate the operation of various devices, such as installing and debugging applications). The default method is to use ADB to command the control unit on the computer to make the Android phone perform Bluetooth broadcasts or other operations, and the control unit to take screenshots or perform other operations on the vehicle's infotainment system.

[0049] Specifically, determining the Bluetooth connectivity compatibility of the vehicle's infotainment system based on the first target information includes:

[0050] The computer-side visual algorithm unit judges the screenshot to see if the Bluetooth device appears in the search box: if it does, the pixel coordinates of the Bluetooth device's name are sent to the vehicle system in a preset manner to perform Bluetooth pairing; if not, the current position information of the vehicle system's search box is read to determine the priority swiping direction to find the Bluetooth device; if the Bluetooth device is still not found, the vehicle system is judged as failing the test.

[0051] Specifically, the method for identifying the pixel coordinates of the Bluetooth device name is as follows: the visual algorithm unit and the coordinate positioning unit call up the image information and coordinate information pre-stored in the storage unit, and determine them through algorithms and coordinate transformation methods.

[0052] Furthermore, determining the Bluetooth connectivity compatibility of the vehicle's infotainment system based on the first target information also includes:

[0053] The pairing process is initiated by the vehicle's infotainment system. The control unit captures a screenshot of the verification code pop-up on the vehicle's infotainment system. The vision algorithm unit judges the verification code pop-up, the coordinate positioning unit determines the coordinates of the sending box, and the vehicle's infotainment system clicks the sending box and waits for a response. The control unit takes a screenshot or photo of the mobile terminal, and the vision algorithm unit judges the screenshot or photo: if the verification code information is correct, the vehicle's infotainment system clicks the agree box; if the verification code information is incorrect or the verification code information is not received from the mobile terminal, the vehicle's infotainment system is judged as failing the test. When the vehicle's infotainment system receives a response from the other party, the vehicle's infotainment system clicks the confirmation box to start the Bluetooth connection.

[0054] Furthermore, determining the Bluetooth connectivity compatibility of the vehicle's infotainment system based on the first target information also includes:

[0055] The control unit displays the phone call interface on the vehicle's infotainment system and takes a screenshot. It then determines the coordinates of the dial pad using a visual algorithm unit and a coordinate positioning unit, dials a number on the second Android phone, and waits for the other party's response.

[0056] The control unit takes a screenshot of the second Android phone, uses a visual algorithm unit to determine whether the incoming call pop-up information is correct, and a coordinate positioning unit to determine the coordinates of the answer box, and then performs the answer operation; if the incoming call pop-up information is incorrect, the vehicle system test is deemed unqualified.

[0057] The control unit takes a screenshot of the vehicle's call interface, determines the coordinates of the hang-up call frame through the visual algorithm unit and the coordinate positioning unit, and then hangs up the call.

[0058] The control unit takes a screenshot of the second Android phone and uses a visual algorithm unit to determine whether the call has ended and whether the screen has returned to the standby screen. If not, the vehicle system test is deemed unqualified.

[0059] The control unit performs a phone call operation between the second Android phone and the vehicle's infotainment system.

[0060] The control unit takes a screenshot of the vehicle's infotainment system and uses a visual algorithm unit to determine whether the incoming call pop-up information is correct and then answers the call. If the incoming call pop-up information is incorrect or there is no incoming call pop-up information, the vehicle's infotainment system is deemed to have failed the test.

[0061] The control unit takes a screenshot of the vehicle's infotainment system and uses a visual algorithm unit to determine whether the system has switched to a call interface. If it has, the system hangs up the call; otherwise, the system fails the test.

[0062] The control unit takes a screenshot of the vehicle's infotainment system and uses a visual algorithm unit to determine whether the call has ended or whether the screen has returned to the standby interface. If not, the infotainment system is deemed to have failed the test.

[0063] Furthermore, determining the Bluetooth connectivity compatibility of the vehicle's infotainment system based on the first target information also includes:

[0064] The control unit brings up the Bluetooth settings menu on the vehicle's infotainment system, finds the name of the Bluetooth device to be deleted in the Bluetooth list, analyzes and judges it through the visual algorithm unit, provides the coordinates of the deletion box through the coordinate positioning unit, and clicks the deletion box on the vehicle's infotainment system.

[0065] The control unit retrieves the Bluetooth device list of the Android phone corresponding to the deleted Bluetooth device and takes a screenshot of all of them; or the control unit and the robotic arm retrieve the Bluetooth device list of the Apple phone corresponding to the deleted Bluetooth device and take a screenshot of all of them with a high-definition camera. Then, the visual algorithm unit determines whether the name of the corresponding vehicle system's Bluetooth device has been deleted from the screenshot or the screenshot. If this step is abnormal, the vehicle system test is deemed unqualified.

[0066] The control unit then retrieves the Bluetooth device list from the vehicle's infotainment system and takes screenshots of all of them. The visual algorithm unit then determines whether the names of the corresponding Android or Apple mobile phone Bluetooth devices have been deleted from all the screenshots. If not, the vehicle's infotainment system is deemed to have failed the test.

[0067] The above-mentioned automatic testing method, after the relevant testing equipment has been installed and connected but before the formal testing, also includes the following preparatory process:

[0068] High-definition cameras were used to take photos and calibrate various Android phones, Apple phones, and vehicle systems.

[0069] Write a test case for the durability of the vehicle's Bluetooth system (a case is a description of a test task for a specific product, reflecting the test plan, method, technology and strategy). Define and name each test action separately, define the expected result of each action in the case, and combine each action and the expected result into a case.

[0070] Based on the defined action and result names, the testing software records and saves the coordinates of the actions and the matched ROI; (ROI is an abbreviation for Region of Interest. In machine vision and image processing, the region to be processed from the image is delineated using rectangles, circles, ellipses, irregular polygons, etc., and is called the Region of Interest.)

[0071] The visual information related to the Bluetooth name of the test phone is recorded and saved. When testing related phones in the future, the corresponding visual information will be read to perform Bluetooth search, connection and related operations.

[0072] Define the Bluetooth search and operation area. Use a high-definition camera or ADB to read the image from the vehicle's infotainment system, outline the Bluetooth search and operation area in the image, and save it for easy intelligent up and down swiping to find relevant Bluetooth devices later.

[0073] The order of editing operations is as follows: Bluetooth connection, verification code input (i.e., verification code pop-up), making a phone call, and deleting the Bluetooth device.

[0074] Specifically, the photo calibration method uses three points to fix a surface. The test phones include multiple Android phones and multiple Apple phones, and the motion coordinates include robot arm coordinates and ADB control coordinates.
