Description

TECHNICAL FIELD

[0001] The utility model relates to vehicle driving test technical field, concretely relates to a vehicle camera for automatic driving test. BACKGROUND

[0002] The current automatic driving test scene is mainly limited to indoor pure virtual environment test or open / closed road conventional scene test. The indoor pure virtual environment test can simulate various traffic scenes and sudden situations such as vehicle intersection, pedestrian crossing and traffic congestion through simulation technology and algorithm. However, the physical rules, traffic behaviors and road conditions in the virtual environment are often simplified and idealized, which is difficult to completely restore the complexity and uncertainty of the real world. For example, the vehicle and pedestrian behaviors in the virtual environment may be too regular, lacking the randomness and diversity in the real world, and the road conditions may be too idealized.

[0003] In contrast, the open / closed road conventional scene test is carried out on various real roads, which can test various road conditions in the real world such as expressway, urban road and rural road. However, this test method is difficult to cover comprehensive climate environment such as rain, snow, haze, strong sunlight and wind sand. In actual test, the tester needs to wait for the occurrence of specific climate conditions to carry out related test, which undoubtedly increases the difficulty and time cost of test. In addition, in order to test in different climate conditions, the tester may need to go to different geographical areas, which will also increase the cost and complexity of test. SUMMARY

[0004] The utility model provides a vehicle camera for automatic driving test to solve the problem that the real automatic driving test scene is difficult to cover comprehensive climate environment.

[0005] In order to realize the above purpose, the utility model adopts the following technical scheme:

[0007] According to the above technical means, based on the transparent display technology, the transparent display screen can dynamically display various images and information while maintaining high transparency. In automatic driving test, the transparent display screen can be used as an environment simulator to test the performance of the automatic driving system under different climate conditions by displaying simulated climate environment images. The transparent display screen does not block the normal view of the camera, thereby ensuring that the automatic driving system can obtain real-world image information in real time during the test process. Further, the camera can collect data after superimposing the simulated climate environment images and the real-world images, which helps to simulate various complex climate driving conditions comprehensively.

[0008] In the utility model, the control module transmits virtual test scene data to the transparent display screen, so that the content of the virtual scene can be adjusted according to different test requirements during automatic driving test, without relying on the occurrence of natural conditions or changing the test location, thereby greatly improving the flexibility and efficiency of the test.

[0012] According to the above technical means, the cavity provides a relatively closed protection space for the control module, blocks dust and moisture from entering, and reduces the risk of damage to the control module caused by moisture or dust erosion. By installing the control module in the cavity of the frame, the integration of each part of the simulation assembly is higher, and the transparent display screen and the control module are more closely combined in physical position, which is beneficial to the more simple and efficient connection between them.

[0013] Further, the simulation assembly further comprises a switch module, the switch module is installed in the cavity, and the switch module is in communication connection with the control module, so that the switch module controls the opening or closing of the transparent display screen through the control module.

[0014] According to the above technical means, by communicating the switch module with the control module, the control module can be used to uniformly operate the opening or closing of the transparent display screen in different use scenarios, thereby saving energy and prolonging the service life of the transparent display screen when it is not needed; the switch module is installed in the cavity, avoiding the problems of space occupation and wiring disorder caused by external installation, making the overall appearance of the camera more simple, and better arranging the components in limited space, thereby improving the compactness and aesthetics of the whole.

[0016] According to the above technical means, the power supply module can provide stable voltage and current to ensure the normal work of the transparent display screen, the control module and the switch module, and the power supply module is installed in the cavity, fully utilizing the space inside the frame, and preventing the power supply module from moving due to the shaking of the test vehicle.

[0017] Further, the simulation assembly further comprises a cover, the frame is installed on the cover, the cover is matched with the camera assembly, and the cover is used to cover the frame on the camera assembly.

[0018] According to the above technical means, the cover is matched with the camera assembly and can cover the frame on the camera assembly, which greatly simplifies the installation process of the simulation assembly, thereby improving the assembly efficiency of the camera; and the cover can prevent dust, water droplets, small particles and other impurities from entering the camera assembly, reducing the risk of data collection errors or equipment damage caused by impurity interference.

[0019] Further, a through hole is formed on the cover, the shape of the through hole is the same as that of the transparent display screen, so that the camera assembly can collect automatic driving test environment data through the transparent display screen.

[0020] According to the above technical means, the shape of the through hole is the same as that of the transparent display screen, which can ensure that the view angle of the camera assembly will not be unnecessarily blocked or distorted when collecting data through the transparent display screen.

[0021] Further, the cover body is formed with a first limiting piece and a second limiting piece, the first limiting piece and the second limiting piece are respectively located on the inner wall of the through hole, and the first limiting piece and the second limiting piece are sequentially arranged along the axial direction of the through hole; the first limiting piece and the second limiting piece are respectively used for abutting against the opposite sides of the frame to mount the frame on the cover body.

[0022] According to the above technical means, the first limiting piece and the second limiting piece are sequentially arranged along the axial direction of the through hole, which can accurately position the frame, and the first limiting piece and the second limiting piece are respectively used for abutting against the opposite sides of the frame, which facilitates the disassembly and installation of the frame, and further facilitates the maintenance of the transparent display screen, the control module, the switch module and the power supply module in the frame.

[0023] Further, the cover body is formed with a third limiting piece, the third limiting piece is located on the inner wall of the through hole, and the third limiting piece is used for abutting against the camera assembly to connect the cover body and the camera assembly.

[0024] According to the above technical means, the third limiting piece is used for abutting against the camera assembly, which provides a direct connection support point between the cover body and the camera assembly, can effectively prevent the cover body from loosening or displacing relative to the camera assembly during the operation of the test vehicle, ensure the stable connection between the cover body and the camera assembly, and improve the universality and compatibility of the equipment.

[0025] Further, the cover body is an elastic structure.

[0026] According to the above technical means, the cover body is an elastic structure, which can produce elastic deformation when the cover body is installed on the camera assembly, so that the cover body can be more easily fitted on the camera assembly and the frame for installation; and because the cover body has elasticity, the cover body can better adapt to camera assemblies and other connected components of different shapes and sizes.

[0027] The beneficial effects of the utility model are as follows:

[0028] 1. The utility model is based on transparent display technology, and the transparent display screen can dynamically display various images and information while maintaining high transparency.

[0042] The utility model proposes a kind of vehicle-mounted camera for automatic driving test, as shown in Figure 1 And Figure 2 It shows, including: camera assembly 1 and simulation component 2, camera assembly 1 is installed on the car body, simulation component 2 is set on camera assembly 1, so that camera assembly 1 can be used to gather automatic driving test environment data through simulation component 2;Simulation component 2 includes transparent display screen 21 and control module 22, transparent display screen 21 is set on camera assembly 1, camera assembly 1 can gather automatic driving test environment data through transparent display screen 21;Control module 22 is connected with transparent display screen 21, control module 22 is used to transmit virtual test scene data to transparent display screen 21, so that camera assembly 1 can gather virtual test scene data and real automatic driving test environment data simultaneously.

[0043] When automatic driving test needs to be carried out, the simulation assembly 2 is set on the camera assembly 1, when a complex test scene is not needed, only the control assembly 22 needs to be turned off, so that the camera assembly 1 collects real automatic driving test environment data through the transparent display screen 21; when a complex climate environment test scene needs to be tested, the control module 22 is turned on, so that the video processing module in the control module 22 converts the video stored in the control module 22 into an electric signal and transmits the electric signal to the transparent display screen 21 and plays the video, so that the camera assembly 1 can collect virtual test scene data and real automatic driving test environment data through the transparent display screen 21 at the same time; when different scenes need to be tested, only the video in the control module 22 needs to be replaced, without the need of repeatedly building or finding a test environment by a test personnel, so that the test efficiency is improved.

[0044] The utility model discloses a transparent display technology, and the transparent display screen 21 can dynamically display various images and information while maintaining high transparency. In automatic driving test, the transparent display screen 21 can be used as an environment simulator to test the performance of the automatic driving system under different climate conditions by displaying simulated climate environment images. The transparent display screen 21 does not block the normal view of the camera, thereby ensuring that the automatic driving system can obtain real-world image information in real time during the test process. Furthermore, the camera can collect data after superimposing simulated climate environment images and real-world images, which helps to simulate various complex climate actual driving conditions comprehensively. Secondly, the utility model discloses a method for transmitting virtual test scene data from the control module 22 to the transparent display screen 21, so that the content of the virtual scene can be adjusted according to different test requirements during automatic driving test, without the need of relying on the occurrence of natural conditions or changing the test location, thereby greatly improving the flexibility and efficiency of the test.

[0045] As shown in Figure 1 and Figure 2 In the embodiment, the simulation assembly 2 further includes a frame 23, and the transparent display screen 21 is supported on the frame 23.

[0046] Preferably, the transparent display screen 21 is integrally formed with the frame 23, which can effectively prevent moisture and dust from entering and will not cause the display screen to be displaced, deformed or damaged due to loose connection, thereby effectively improving the structural stability of the entire assembly.

[0047] The frame 23 supports the transparent display screen 21, prevents the transparent display screen 21 from shaking or moving due to vehicle driving, enables the transparent display screen 21 to maintain a stable position and posture, and the frame 23 can serve as a buffer and protection structure to reduce damage of the transparent display screen 21 caused by external forces. When the simulation assembly 2 is installed, the transparent display screen 21 is first installed on the frame 23, and then the entire frame 23 is installed on the camera assembly 1, so that the installation is more convenient and fast.

[0048] As shown in Figure 1 In this embodiment, a cavity (not shown in the figure) is formed in the frame 23, and the control module 22 is installed in the cavity. The cavity provides a relatively closed protection space for the control module 22, blocks dust and moisture from entering, and reduces the risk of damage to the control module 22 caused by moisture or dust erosion. Installing the control module 22 in the cavity of the frame 23 makes the integration of each part of the simulation assembly 2 higher, and makes the transparent display screen 21 and the control module 22 more closely combined in physical position, which is beneficial to more concise and efficient connection between them.

[0049] As shown in Figure 1 In this embodiment, the simulation assembly 2 further includes a switch module 24, the switch module 24 is installed in the cavity, and the switch module 24 is in communication connection with the control module 22, so that the switch module 24 controls the opening or closing of the transparent display screen 21 through the control module 22.

[0050] Preferably, the switch module 24 is controlled remotely, so that the tester can operate the opening or closing of the transparent display screen 21 without directly contacting the camera, thereby ensuring the safety of the tester.

[0051] By communicating the switch module 24 with the control module 22, the opening or closing of the transparent display screen 21 can be uniformly operated by the control module 22 in different use requirement scenarios, thereby saving energy and prolonging the service life of the transparent display screen 21 when it is not needed to be used. Installing the switch module 24 in the cavity avoids the problems of space occupation and messy wiring caused by external installation, makes the overall appearance of the camera more simple, and can better arrange the components in the limited space, thereby improving the overall compactness and aesthetics.

[0052] As shown in Figure 1 In this embodiment, the simulation assembly 2 further includes a power supply module 25, the power supply module 25 is installed in the cavity, and the power supply module 25 is in communication connection with the transparent display screen 21, the control module 22 and the switch module 24, so that the power supply module 25 supplies power to the transparent display screen 21, the control module 22 and the switch module 24.

[0053] Preferably, the power supply module 25 uses a battery pack, which frees the transparent display screen 21 from dependence on an external fixed power source, so that the camera assembly 1 can simultaneously collect virtual test scene data and real autonomous driving test environment data through the transparent display screen 21.

[0054] The power supply module 25 can provide stable voltage and current to ensure the normal operation of the transparent display screen 21, control module 22 and switch module 24. The power supply module 25 is installed in the cavity, making full use of the space inside the frame 23, while preventing the power supply module 25 from moving due to the vibration of the test vehicle.

[0055] like Figure 3 As shown, in this embodiment, the simulation component 2 also includes a cover 26, and a frame 23 is mounted on the cover 26. The cover 26 is adapted to the camera component 1, and the cover 26 is used to fit the frame 23 onto the camera component 1.

[0056] The cover 26 is compatible with the camera assembly 1 and can fit the frame 23 onto the camera assembly 1. This design greatly simplifies the installation process of the analog assembly 2, thereby improving the assembly efficiency of the camera. In addition, the cover 26 can prevent external dust, water droplets, small particles and other impurities from entering the camera assembly 1, reducing the risk of data acquisition errors or equipment damage caused by impurities.

[0057] like Figure 4 As shown, in this embodiment, a through hole 261 is formed on the cover 26. The shape of the through hole 261 is the same as that of the transparent display screen 21, so that the camera assembly 1 can collect autonomous driving test environment data through the transparent display screen 21.

[0058] The through-hole 261 has the same shape as the transparent display screen 21. This design ensures that the viewing angle of the camera component 1 is not unnecessarily obstructed or distorted when it collects data through the transparent display screen 21.

[0059] like Figure 4 As shown, in this embodiment, a first limiting member 262 and a second limiting member 263 are formed on the cover 26. The first limiting member 262 and the second limiting member 263 are respectively located on the inner wall of the through hole 261, and the first limiting member 262 and the second limiting member 263 are arranged sequentially along the axial direction of the through hole 261. The first limiting member 262 and the second limiting member 263 are respectively used to abut against the opposite sides of the frame 23 to install the frame 23 on the cover 26.

[0060] Preferably, the first limiting member 262 abuts against one side of the frame 23, so that the first limiting member 262 can limit the shaking of the components inside the cavity and prevent the components inside the cavity from falling out due to the vibration generated when the vehicle is running; and when the components inside the cavity need to be replaced, the replacement can be completed simply by opening the first limiting member 262.

[0061] The first limiting piece 262 and the second limiting piece 263 are arranged in sequence along the axial direction of the through hole 261, which can precisely position the frame 23. In addition, the first limiting piece 262 and the second limiting piece 263 are respectively used for abutting against the opposite sides of the frame 23. This mounting method facilitates the disassembly and assembly of the frame 23, and further facilitates the maintenance of the transparent display screen 21, the control module 22, the switch module 24 and the power supply module 25 in the frame 23.

[0062] As shown in Figure 4 In the embodiment, the cover body 26 further has a third limiting piece 264 located in the inner wall of the through hole 261. The third limiting piece is used for abutting against the camera assembly 1, so as to connect the cover body 26 and the camera assembly 1.

[0063] Preferably, the third limiting piece 264 and the camera assembly 1 are in transition fit, so that the cover body 26 can be closely sleeved on the camera assembly 1, preventing the transparent display screen 21 from falling out due to the vibration of the vehicle during driving.

[0064] The third limiting piece 264 is used for abutting against the camera assembly 1, providing a direct connection support point between the cover body 26 and the camera assembly 1. This can effectively prevent the cover body 26 from loosening or displacing relative to the camera assembly 1 during the operation of the test vehicle, ensuring the stable connection between the cover body 26 and the camera assembly 1, and improving the universality and compatibility of the camera.

[0065] As shown in Figure 4 In the embodiment, the cover body 26 is of an elastic structure.

[0066] Preferably, the cover body 26 is of a rubber structure. Rubber is relatively easy to process into various complex shapes during manufacturing, so that the cover body 26 can be customized and designed according to the specific needs of the camera, so that it can be well installed and matched with the simulation assembly 2. In addition, the cover body 26 of the rubber structure has excellent elasticity, which can well fasten the frame 23 and the camera assembly 1 together to prevent them from falling off.

[0067] Preferably, the cover body 26 is of an elastic structure. When the cover body 26 is installed on the camera assembly 1, it can elastically deform, so that the cover body 26 can be more easily sleeved on the camera assembly 1 and installed in cooperation with the frame 23. In addition, due to the elasticity of the cover body 26, the cover body 26 can better adapt to camera assemblies 1 of different shapes and sizes and other components connected thereto.

[0068] The above examples are only preferred embodiments for fully illustrating the present application, and the protection scope of the present application is not limited thereto. Any equivalent substitutions or transformations made by those skilled in the art based on the present application are within the protection scope of the present application.
