[0001] The present application relates to the technical field of vehicle testing, in particular to an auxiliary testing device and a testing method. BACKGROUND

[0002] The vehicle-mounted signal device is used to realize functions such as remote control and remote monitoring of the vehicle. Taking the vehicle's passive unlocking as an example, the passive unlocking is a manifestation of the vehicle's remote control function. The vehicle key and the vehicle-mounted signal device can remotely transmit and receive signals. When the user carries the vehicle key and approaches the vehicle, the vehicle-mounted signal device monitors that the distance between the vehicle key and the vehicle is less than a first set distance, and the vehicle-mounted processor judges that the user will drive the vehicle, and automatically controls the vehicle door to be unlocked, that is, passive unlocking. When the user carries the vehicle key and moves away from the vehicle, the vehicle-mounted signal device monitors that the distance between the vehicle key and the vehicle is greater than a second set distance, and the vehicle-mounted processor judges that the user will leave the vehicle, and automatically controls the vehicle door to be locked, that is, passive locking.

[0003] The response distance of the vehicle-mounted signal device generally needs to be tested in practice. For example, for passive unlocking, the actual distance between the vehicle key and the vehicle when the vehicle is unlocked needs to be obtained in a preset direction, and it is checked whether the obtained actual distance is consistent with the corresponding set distance. In related technologies, the actual distance is generally obtained by using the human eye to visually measure the preset direction, and the testing accuracy is poor. SUMMARY

[0038] The embodiment of the present application provides an auxiliary testing device for assisting in testing response distance of a vehicle-mounted signal device. The vehicle-mounted signal device is a device for transmitting and receiving signals remotely of a vehicle, and is used for realizing remote monitoring and remote control of the vehicle, and can be a Bluetooth device, a radio frequency identification (RFID) device, a vehicle-mounted wireless local area network device, and the like. The response distance of the vehicle-mounted signal device can refer to various types of distances, such as a Bluetooth connection distance, a Bluetooth disconnection distance, a wireless local area network connection distance, a wireless local area network disconnection distance, and a control signal effective distance between the vehicle and a moving signal device. The moving signal device is a device for transmitting signals to the vehicle-mounted signal device and / or receiving signals transmitted by the vehicle-mounted signal device, and the moving signal device moves relative to the vehicle. The moving signal device transmits information to the vehicle-mounted signal device to control the vehicle through the vehicle-mounted signal device, that is, remote control of the vehicle. The moving signal device receives state information of the vehicle transmitted by the vehicle-mounted signal device to monitor the state of the vehicle, that is, remote monitoring of the vehicle.

[0039] Taking non-inductive unlocking of the vehicle as an example, the moving signal device refers to a car key and the like. Generally, the car key is connected with the vehicle-mounted signal device through a Bluetooth signal, that is, the vehicle-mounted signal device and the car key are both Bluetooth devices. In this case, the response distance of the vehicle-mounted signal device can include a Bluetooth connection distance, a Bluetooth disconnection distance, an unlocking distance, and a locking distance between the car key and the vehicle, and the like. The Bluetooth connection distance is the distance between the car key and the vehicle when the vehicle-mounted signal device and the car key are connected through Bluetooth, and the Bluetooth disconnection distance, the unlocking distance, and the locking distance are the same. In some embodiments of the present application, the car key can be replaced by a device capable of transmitting and receiving Bluetooth signals, such as a mobile phone, a notebook computer, a tablet computer, and a wearable electronic device.

[0040] The response distance of the vehicle-mounted signal device generally needs to be tested in practice to ensure the reliability of the operation of the vehicle-mounted signal device. The embodiment of the present application provides an auxiliary testing device for assisting in testing the response distance of the vehicle-mounted signal device to improve the accuracy of testing the response distance of the vehicle-mounted signal device.

[0041] Please refer to Figure 1 、 Figure 2 、 Figure 3 、and Figure 4The auxiliary testing device provided by the embodiment of the present application is used for assisting in testing the response distance of the vehicle-mounted signal device. Figure 1 A schematic view of the guide light beam relative to the vehicle in different poses for some embodiments of the present application; Figure 2 A schematic view of the structure of the auxiliary testing device arranged on the vehicle for some embodiments of the present application; Figure 3 A schematic view of the structure of the auxiliary testing device for some embodiments of the present application; Figure 2 A local enlarged view of position A in FIG. 4; Figure 4 A schematic view of the structure of the auxiliary testing device for some embodiments of the present application; the auxiliary testing device comprises a base frame 1, a guide light beam generator 2 and an adjusting member 4. The base frame 1 is used for being fixed on the vehicle 01; the adjusting member 4 is rotationally connected with the base frame 1; the guide light beam generator 2 is arranged on the adjusting member 4; the guide light beam generator 2 is used for emitting a guide light beam a in a direction away from the vehicle 01; the guide light beam generator 2 has at least a first pose; in the case that the guide light beam generator 2 is in the first pose, the extension path of the guide light beam a is not parallel to the first axis, so that in the process that the adjusting member 4 drives the guide light beam generator 2 to rotate relative to the base frame 1, the guide light beam a rotates around the first axis. With such a structure, the guide light beam generator 2 can emit the guide light beam a, the guide light beam a extends in a direction away from the vehicle 01, the extension path of the guide light beam a can clearly demarcate the preset direction, and the accuracy is high, which can be used as a basis for judging whether the preset direction is deviated, thereby improving the accuracy of obtaining the distance in the preset direction. Therefore, the auxiliary testing device provided by the embodiment of the present application can improve the accuracy of testing the response distance of the vehicle-mounted signal device.

[0042] Moreover, please refer to Figure 1 , Figure 2 , Figure 3 , and Figure 4 The auxiliary testing device provided by the embodiment of the present application is used for assisting in testing the response distance of the vehicle-mounted signal device.

[0043] It can be understood that, please refer to Figure 1 , Figure 2 , Figure 3 , and Figure 4 , it is relatively convenient to realize the preset direction visualization by using the guide light beam a. The guide light beam generator 2 is small and light, which is beneficial to make the auxiliary test device small and light. When a plurality of vehicles 01 need to be tested, the auxiliary test device can be arranged on the plurality of vehicles 01 respectively, and the operation is relatively convenient. It needs to be explained that the guide light beam generator 2 in the embodiment of the application can have various implementation forms, such as a laser, and the guide light beam a is a laser beam.

[0044] In order to facilitate the understanding of the auxiliary test device, the test method provided by the embodiment of the application is described below, which is used for testing the response distance of the vehicle-mounted signal device by using the auxiliary test device provided by the embodiment of the application, referring to Figure 5 , comprising:

[0045] S401, controlling the motion signal device to move along the guide light beam;

[0046] S402, acquiring the distance between the motion signal device and the vehicle when the target event triggered by the vehicle-mounted signal device and / or the motion signal device; wherein the motion signal device and the vehicle-mounted signal device transmit information to each other; the relative attitude of the guide light beam and the vehicle changes at least once.

[0047] The auxiliary test method provided by the embodiment of the application can calibrate the preset direction by the guide light beam a, and the motion signal device is not easy to deviate from the preset direction in the process of controlling the motion signal device to move, which is beneficial to improve the accuracy of the response distance test of the vehicle-mounted signal device. Moreover, the relative attitude of the guide light beam a and the vehicle 01 changes at least once in the test process, which is beneficial to the test work of the response distance of the vehicle-mounted signal device in multiple preset directions.

[0048] It needs to be explained that the distance between the motion signal device and the vehicle 01 acquired when the target event triggered by the vehicle-mounted signal device and / or the motion signal device is the response distance. Exemplarily, when the target event is that the vehicle-mounted signal device controls the vehicle door to be unlocked, the distance between the motion signal device and the vehicle 01 acquired is the unlocking distance.

[0049] In order to facilitate understanding, the response distance test method of the vehicle-mounted signal device is described below by taking the non-inductive unlocking of the vehicle as an example. Referring to Figure 6 , Figure 6 is a flowchart of the locking distance test method in some embodiments of the application, mainly comprising the following steps:

[0050] S101, moving in the direction away from the vehicle along the extension path of the guide light beam;

[0051] S102, check whether the door is closed; if the door is not closed, continue to move away from the vehicle along the extension path of the guide light beam;

[0052] S103, if the door is closed, obtain the closing distance and continue to move in this direction;

[0053] S104, check whether the Bluetooth is disconnected; if the door Bluetooth is not disconnected, continue to move away from the vehicle along the extension path of the guide light beam;

[0054] S105, if the door Bluetooth is disconnected, obtain the Bluetooth disconnection distance.

[0055] It needs to be explained that for step S101, moving away from the vehicle 01 along the extension path of the guide light beam a can be that a person carries a car key or other motion signal device along the guide light beam a, or that a motion device carries a motion signal device along the guide light beam a. The motion device can be a robot or a trolley, etc. The motion device is provided with a visual sensor for detecting the guide light beam a, so that the motion device can automatically move along the guide light beam a; of course, it can also be that a person manually controls the motion device, and observes the relative position between the motion device and the guide light beam a with the naked eye, so that the motion device moves along the guide light beam a. As the main body of the method, the person is more convenient to realize, and the person only needs to carry the motion signal device to walk. As the main body of the method, the motion of the motion device is more accurate and stable, which is conducive to improving the accuracy of the test.

[0056] It can be understood that in the process of moving away from the vehicle 01, the car key or other motion signal device gradually moves away from the vehicle 01 along the guide light beam a, and when the distance between the motion signal device and the vehicle 01 is greater than a certain distance, the door will be automatically closed. At this time, the distance between the motion signal device and the vehicle 01 is the closing distance. Continue to move away from the vehicle 01 until the Bluetooth connection between the motion signal device and the vehicle signal device is disconnected, at which time the distance between the motion signal device and the vehicle 01 is the Bluetooth disconnection distance.

[0057] It can be understood that the extended path of the guide light beam a can visualize the preset direction with high accuracy, and can be used as a basis for judging whether the preset direction is deviated. That is, during the movement along the guide light beam a, it is not easy to deviate from the preset direction, so that the response distance of the vehicle-mounted signal device in the preset direction can be accurately obtained. In some embodiments of the present application, the guide light beam generator 2 has multiple light emission modes, different light emission modes correspond to different extended paths of the guide light beam a, and the extended paths of the guide light beam a corresponding to different light emission modes are arranged along the circumference, and the above-mentioned extended paths are all radially extended along the circumference. In some embodiments of the present application, the extended path of the guide light beam a is in the horizontal direction. In this way, it is beneficial to improve the accuracy of the test.

[0058] Similar to the lock distance test method, referring to Figure 7 , Figure 7 is a flowchart of the unlock distance test method in some embodiments of the present application, mainly including the following steps:

[0059] S201, moving along the extended path of the guide light beam to the direction close to the vehicle;

[0060] S202, checking whether the Bluetooth is connected; if the vehicle door Bluetooth is not connected, continue to move along the extended path of the guide light beam to the direction close to the vehicle;

[0061] S203, if the vehicle door Bluetooth is connected, obtaining the Bluetooth connection distance and continuing to move in this direction;

[0062] S204, checking whether the vehicle door is unlocked; if the vehicle door is not unlocked, continue to move along the extended path of the guide light beam to the direction close to the vehicle;

[0063] S205, if the vehicle door is unlocked, obtaining the unlock distance.

[0064] Similarly, referring to Figure 8 , Figure 8 is a flowchart of the unlock distance test method in some embodiments of the present application, mainly including the following steps:

[0065] S301, moving along the extended path of the guide light beam to the direction away from the vehicle;

[0066] S302, checking whether the vehicle door is locked; if the vehicle door is not locked, continue to move along the extended path of the guide light beam to the direction away from the vehicle;

[0067] S303, if the vehicle door is locked, obtaining the lock distance and continuing to move in this direction;

[0068] S304, checking whether the Bluetooth is disconnected; if the vehicle door Bluetooth is not disconnected, continue to move along the extended path of the guide light beam to the direction away from the vehicle;

[0069] S305, if the door Bluetooth is disconnected, the Bluetooth disconnection distance is obtained.

[0070] S306, the guide light beam extension path is extended to the direction close to the vehicle;

[0071] S307, it is checked whether the Bluetooth is connected; if the door Bluetooth is not connected, the guide light beam extension path is continuously extended to the direction close to the vehicle;

[0072] S308, if the door Bluetooth is connected, the Bluetooth connection distance is obtained, and the direction is continuously extended;

[0073] S309, it is checked whether the door is unlocked; if the door is not unlocked, the guide light beam extension path is continuously extended to the direction close to the vehicle;

[0074] S310, if the door is unlocked, the unlocking distance is obtained.

[0075] Referring to Figure 4 , Figure 9 and Figure 10 , in some embodiments of the present application, the first axis is parallel to the horizontal direction, so that the adjusting member 4 can drive the guide light beam generator 2 to move to the target posture, and the extension path of the guide light beam a is parallel to the horizontal direction. With this structure, the adjusting member 4 rotates relative to the base frame 1, so that the pitch angle of the guide light beam generator 2 can be adjusted. Adjusting the extension path of the guide light beam a to the direction parallel to the horizontal direction is beneficial to making the extension distance of the guide light beam a farther, and is also convenient for the observation of the human eye, which can improve the accuracy of the test.

[0076] Referring to Figure 4 , Figure 9 and Figure 10 , in the embodiments of the present application, the guide light beam generator 2 arranged on the adjusting member 4 can have various implementation forms. In some embodiments of the present application, the guide light beam generator 2 can be fixed on the adjusting member 4. In some embodiments of the present application, the guide light beam generator 2 can also be movably arranged on the adjusting member 4, so that the guide light beam generator 2 has various postures relative to the adjusting member 4. The guide light beam a emitted by the guide light beam generator 2 in different postures relative to the adjusting member 4 has different angles with the first axis. In this way, the posture of the extension path of the guide light beam a can be adjusted in a large range, which is convenient for the test of the response distance of the vehicle-mounted signal device in different preset directions. It should be explained that the different angles can be different in size, or the same in size but opposite in direction.

[0077] Referring to Figure 4 , Figure 9 and Figure 10In some embodiments of the present application, the adjusting member 4 can be provided with a plurality of installation cavities 411, each of which is formed with a first light outlet opening; the guide light beam generator 2 can be arranged in each of the installation cavities 411 and emit the guide light beam a in a direction away from the vehicle 01 through the corresponding first light outlet opening; the axes of the first light outlet openings of the plurality of installation cavities 411 are different from the first axis, so that the guide light beams a emitted through different first light outlet openings have different angles with the first axis. In this way, the plurality of installation cavities 411 provide a plurality of installation positions for the guide light beam generator 2, so that the guide light beam generator 2 has a plurality of different installation poses relative to the adjusting member 4.

[0078] With reference to Figure 4 , Figure 9 and Figure 10 In some embodiments of the present application, the axes of the plurality of first light outlet openings are perpendicular to the reference line, and the reference line is perpendicular to the first axis. In this way, on the one hand, it is beneficial to meet the requirement of adjusting the pose of the guide light beam a in a larger range, and on the other hand, it is beneficial to reduce the space required for arranging the plurality of installation cavities 411, save materials and reduce costs. On this basis, in some embodiments of the present application, the plurality of first light outlet openings are arranged in a circle around the reference line, and the axial direction of the first light outlet opening is the radial direction of the reference line. In this way, the arrangement of the plurality of installation cavities 411 is more compact, which is beneficial to save materials and reduce costs. In some embodiments of the present application, along the extension path of the reference line, the plurality of first light outlet openings are flush. In this way, the arrangement of the plurality of installation cavities 411 is more compact, which is beneficial to save materials and reduce costs.

[0079] With reference to Figure 4 , Figure 9 and Figure 10 In some embodiments of the present application, the first light outlet openings are uniformly arranged in a circle around the reference line. The angle between the extension paths of the guide light beams a of two adjacent first light outlet openings is 0-90 degrees. In some embodiments of the present application, the angle can be 30 degrees.

[0080] With reference to Figure 4 , Figure 9 and Figure 10In some embodiments of the present application, the mounting cavity 411 is further formed with a second light outlet opening, which is arranged opposite to the first light outlet opening along the axial direction of the first light outlet opening, and the pilot beam generator 2 can emit the pilot beam a in a direction away from the vehicle 01 through the second light outlet opening. In this way, the pilot beam generator 2 can emit the pilot beam a in two opposite directions relative to the vehicle 01 through the first light outlet opening and the second light outlet opening, which is conducive to meeting the demand of adjusting the attitude of the pilot beam a in a larger range. Moreover, the pilot beam generator 2 has two installation attitudes corresponding to each mounting cavity 411, one is to emit the pilot beam a in a direction away from the vehicle 01 through the first light outlet opening, and the other is to emit the pilot beam a in a direction away from the vehicle 01 through the second light outlet opening, which is conducive to reducing the number of mounting cavities 411 and improving the compactness of the structure. In some embodiments of the present application, the first light outlet opening and the corresponding second light outlet opening are respectively located on opposite sides of the reference line, on the basis that the axial direction of the first light outlet opening is the radial direction of the reference line. In this way, the arrangement of the plurality of mounting cavities 411 is relatively compact, which is conducive to saving materials and reducing costs.

[0081] With reference to Figure 4 , Figure 9 and Figure 10 , in the embodiments of the present application, the mounting cavity 411 can have various implementation forms, such as a mounting groove, a mounting hole, etc. In some embodiments of the present application, the adjusting member 4 is formed with a plurality of protrusions, which are arranged in a circumferential direction, and the axial direction of the circumferential arrangement is perpendicular to the first axis; two adjacent protrusions are used to jointly form the mounting cavity 411, and the axial direction of the first light outlet opening is the radial direction of the circumferential arrangement; along the radial direction of the circumferential arrangement, one end of the pilot beam generator 2 is limited between one set of adjacent protrusions, and the other end of the pilot beam generator 2 is limited between another set of adjacent protrusions. In this way, the plurality of mounting cavities 411 are implemented by the plurality of protrusions, which is convenient to process and compact in structure. The two ends of the pilot beam generator 2 are respectively limited between two sets of adjacent protrusions, which is conducive to improving the reliability of the installation of the pilot beam generator 2. It can be understood that one set of adjacent two protrusions are used to jointly form the first light outlet opening, and the other set of adjacent two protrusions are used to jointly form the second light outlet opening.

[0082] With reference to Figure 4 , Figure 9 and Figure 11 ​In some embodiments of the present application, the base frame 1 comprises two opposite vertical plates 12, each of which is formed with a second through hole 121, and the second through holes 121 of the two vertical plates 12 are coaxial; the adjusting member 4 is arranged between the two vertical plates 12; the auxiliary testing device further comprises two mounting members 5, each of which is matched with the through hole of the corresponding vertical plate 12 to be rotatably connected with the corresponding vertical plate 12, and each of the two mounting members 5 is detachably connected with the adjusting member 4 to rotatably connect the adjusting member 4 with the base frame 1; each of the two mounting members 5 is formed with a stop block 51 arranged on the side of the corresponding vertical plate 12 away from the adjusting member 4, and the circumferential profile of the stop block 51 is larger than that of the second through hole 121 to limit the movement of the adjusting member 4 along the axial direction e of the second through hole. With this structure, the adjusting member 4 is supported on the two vertical plates 12 by the two mounting members 5, and the installation of the adjusting member 4 is more stable. Moreover, the adjusting member 4 is supported on the two vertical plates 12 by the two mounting members 5, and the installation of the adjusting member 4 on the base frame 1 is also more convenient. For the convenience of understanding, the installation process is described below. During the installation process, one of the mounting members 5 can be first arranged in the corresponding second through hole 121, then the adjusting member 4 is connected with the mounting member 5, and then the other mounting member 5 is arranged in the corresponding second through hole 121, and the adjusting member 4 is connected with the mounting member 5. It can be understood that, in the embodiments of the present application, the axis of rotation of the adjusting member 4 relative to the base frame 1 is the axis of the second through hole 121.

The bottom surface 111 of the base frame 1, that is, the side surface corresponding to the bearing surface, is opposite to the bearing surface. It can be understood that the base frame 1 can be placed at different positions of the vehicle 01, and it cannot be fully guaranteed that the bottom surface 111 of the base frame 1 is fully attached to the bearing surface at each position. In addition, the auxiliary testing device provided in the embodiments of the present application can be used for different models of vehicles 01, and it also cannot be guaranteed that the bottom surface 111 of the base frame 1 is fully attached to the bearing surface of the different models of vehicles 01. The bottom surface 111 and the bearing surface are not fully attached, that is, a placement gap c is formed between the bottom surface 111 and the bearing surface. The placement gap c in the embodiments of the present application is the gap caused by the non-attachment of the bottom surface 111 and the bearing surface. At least a part of the adjusting member 3 can be supported in the placement gap c to fill the placement gap c, which is beneficial to improve the stability of the auxiliary testing device placed on the vehicle 01. Of course, please refer to Figure 14 In some embodiments of the present application, there is also a case that the bottom surface 111 is fully attached to the vehicle 01, and no placement gap c is formed between the bottom surface 111 and the vehicle 01.

[0090] Referring to Figure 4 , Figure 12 and Figure 13In some embodiments of the present application, the bottom surface 111 has an adsorption part. In this way, the bottom surface 111 is adsorbed with the bearing surface, which is conducive to improving the stability of the base 1 placed on the vehicle 01. In some embodiments of the present application, the adsorption part is made of a magnetic material, and the adsorption force between the bottom surface 111 and the bearing surface is a magnetic force.

[0091] With reference to Figure 4 , Figure 12 and Figure 13 , in some embodiments of the present application, the adjusting part 3 has a first attitude and a second attitude, in the case of being in the first attitude, the adjusting part 3 does not protrude from the bottom surface 111, and in the case of being in the second attitude, at least a part of the adjusting part 3 is supported in the placement gap c. In this way, the structure is conducive to improving the adaptability of the base 1 to different bearing surfaces. In the case that the bottom surface 111 is well attached to the vehicle 01, the adjusting part 3 can be in the first attitude. Of course, in some other embodiments of the present application, the adjusting part 3 can only have the first attitude and not have the second attitude, that is, the adjusting part 3 always protrudes relative to the bottom surface 111, but the protruding distance is adjustable, so that the adjusting part 3 can be supported on the bearing surface or separated from the bearing surface.

[0092] With reference to Figure 4 , Figure 12 and Figure 13 , in some embodiments of the present application, the adjusting part 3 is an external thread part, which is threadedly connected with the base 1 to be movably arranged on the base 1; the first direction is the axial direction of the external thread part.
