Technical Field

[0002] The present invention relates to the technical field of vehicle assisted driving, and in particular to a vehicle-mounted assisted driving instrument. Background Art

[0003] With the increasing popularity of intelligent assisted driving technology, more and more assisted driving devices are appearing on the market. Current assisted driving devices are usually integrated into the vehicle cab, and use the display screen inside the cab to display the real-time in-vehicle video of the vehicle driving scene. However, the size of the display screen inside the cab is usually fixed, and it is usually mainly used to display visible light in-vehicle video. In harsh environments such as low light, rain, snow, and heavy fog, the driver's vision is obstructed, and the display of visible light images cannot effectively assist the driver in identification and judgment. With the development of infrared imaging technology, how to simultaneously utilize infrared and visible light images in in-vehicle assisted driving to improve driving safety performance is gaining more and more attention. The current architecture of assisted driving devices is difficult to support the demand for expanded applications that use infrared imaging technology to improve assisted driving performance.

[0036] Referring to Figures 1-4 , one embodiment of the present invention provides an in-vehicle assisted driving device, comprising a main body 1 and a bracket 2. The main body 1 includes a controller and a display screen 11. The controller is connected to an in-vehicle camera, and the display screen 11 is disposed on one side of the main body 1. The controller controls the display screen 11 to display the in-vehicle image formed by image data captured by the in-vehicle camera. The bracket 2 is rotatably connected to the main body 1. The bracket 2 rotates relative to the main body 1 to form a support state and a storage state. When the bracket 2 rotates relative to the main body 1 to form the support state, the bracket 2 and the main body 1 together form a mounting position for a smart terminal device. When the bracket 2 rotates relative to the main body 1 to form the storage state, the bracket 2 is stored in the main body 1. The smart terminal device can be stably and conveniently placed in the mounting position provided by the bracket 2 and the main body 1, providing various assistance during in-vehicle assisted driving. It can also serve as an additional display device for the main body 1, communicating with the smart terminal device through the main body 1 to transmit data with the smart terminal device and display the in-vehicle image through the smart terminal device.

[0037] A rotatably connected bracket part 2 is provided on the host body 1 of the vehicle-mounted assisted driving instrument. The bracket part 2 can rotate relative to the host body 1 to form a bracket state and a storage state, so that the host body 1 can provide a bracket function for stably placing the smart terminal device through the bracket part 2. In this way, the host body 1 integrates the bracket function for stably placing the smart terminal device and also provides the storage function of the bracket part 2. Not only is the structure more compact, but it is also more conducive to the smart terminal device providing an installation state that is more conducive to user viewing in the bracket state provided by the bracket part 2, thereby improving the driving experience of viewing in-vehicle images on dual screens.

[0038] In addition, the smart terminal device can also serve as an additional display device of the host body 1, and transmit data through a communication connection with the host body 1, so that the host body 1 can display the vehicle-mounted image formed by the image data collected by the vehicle-mounted camera on the local display screen 11, and at the same time, send the vehicle-mounted image to the smart terminal device in real time for display. In this way, thanks to the development and popularization of various portable smart terminal devices, the display of vehicle-mounted images is no longer limited to relying on the display function of the host body 1 of the vehicle-mounted assisted driving instrument itself, but uses the data interaction between the host body 1 and the smart terminal device to provide a dual-screen display, supporting the vehicle-mounted assisted driving instrument to display the video data source adapted to the scene in real time according to the scene conditions. For example, the dual-screen display of the host body 1 and the smart terminal device is supported to expand the use of infrared and visible light images in vehicle-mounted assisted driving, thereby facilitating the driver to view clear vehicle-mounted images, improving driving safety, and greatly improving the convenience and practicality of the host side.

[0039] Among them, the vehicle-mounted assisted driving instrument also includes a rotating part 3, and the bracket 2 is rotatably connected to the host body 1 through the rotating part 3. The host body 1, the bracket part 2 and the rotating part 3 are integrated into an integral structure to form the host of the vehicle-mounted assisted driving instrument. The host can be a portable integral structure formed by the host body 1, the bracket part 2 and the rotating part 3, which can be installed in the vehicle cab by a detachable connection method, so as to facilitate the addition of a dual-screen display assisted driving function to the original vehicle by adding the host. Optionally, the host can also be pre-integrated and installed in the vehicle cab during vehicle design. The vehicle-mounted camera is usually located outside the vehicle, and a communication connection can be established between the host body 1 and the vehicle-mounted camera through a wired or wireless communication method. In this embodiment, the host body 1 and the vehicle-mounted camera are connected to each other using a FAKRA interface and a coaxial cable. The vehicle-mounted camera transmits the collected image data to the host body 1 in real time in the form of a video stream.

[0040] Please refer to Figures 5 and 6 . Before a user prepares to drive a vehicle, they can use their own smart terminal, such as a mobile phone, as an extended display device for the in-vehicle driver assistance system. The initial state of the bracket 2 is typically the stowed state. The user can manually rotate the bracket 2 to position it relative to the host body 1. When the user no longer needs to use the smart terminal device, the user can rotate the bracket 2 to switch it back to the stowed state relative to the host body 1. In this embodiment, the bracket 2 is provided on the host body 1. The bracket 2 rotates relative to the host body 1 to form a stowed state and a stowed state, so that the host body 1 and the bracket 2 are integrated together to form the driver assistance system. This system has both driver assistance functions and a support function. During installation, the entire system only needs to be installed in the vehicle, making the installation process simple and easy to implement. In addition, the communication connection between the host body 1 and the smart terminal device enables data transmission between the host body 1 and the smart terminal device, allowing the in-vehicle image to be displayed on the smart terminal device.

[0041] Referring to FIG. 2 , in an optional embodiment, a receiving space 121 is formed on the upper surface of the host body 1. The bracket 2 is rotatably connected to one side of the receiving space, i.e., the rotating member 3 is disposed on one side of the receiving space 121. When the bracket 2 rotates relative to the host body 1 to form a supporting position, the bracket 2 rotates from within the receiving space 121 in a direction away from the upper surface of the host body 1, forming a space between the bracket 2 and the upper surface of the host body 1 for placing a smart terminal device. When the smart terminal device is placed, one end of the bracket 2 abuts the inner side of the bracket 2 and the other end abuts the upper surface of the host body 1. When the bracket 2 rotates relative to the host body 1 to form a storage position, the bracket 2 is stored in the receiving space 121. The receiving space 121 can be formed by a recess in the upper surface of the host body 1 or directly formed on the upper surface of the host body 1. Furthermore, a stopper can be provided at the front end of the receiving space 121, and / or an anti-slip pad or a retaining groove can be provided on the upper surface of the host body 1 to prevent the smart terminal device from slipping during use. In this embodiment, the upper surface of the host is recessed to form a receiving space 121, so that when the bracket 2 is in the bracket state, a recessed space for placing the smart terminal device is formed between the bracket and the upper surface of the host body 1, so that the smart terminal device is not easily dropped during driving of the car. When the bracket is in the storage state, the bracket 2 is stored in the receiving space 121 formed by the recessed upper surface of the host body 1, thereby improving the aesthetics of the entire device.

[0042] Please refer to Figures 7 and 8. It should be further explained that a magnetic member 21 is provided on the bracket 2. The magnetic member 21 provides a magnetic attraction force to attract the smart terminal device and place it on the bracket 2. The bracket 2 includes an upper shell 22 and a lower shell 23 that matches the upper shell 22. The magnetic member 21 can be provided on the inner surface of the upper shell 22 to improve the aesthetics and compactness of the entire device, or it can be provided on the outer surface of the upper shell 22 to improve the magnetic attraction force between the smart terminal device and the bracket 2. The magnetic member 21 can be a magnet. For example, the magnetic member 21 includes four circular magnets distributed at the four corners of the bracket 2, and multiple magnets are provided at intervals on the inner surface of the upper shell 22. The upper shell 22 and the lower shell 23 can be connected by a snap-on or threaded connection. In this embodiment, the upper shell 22 and the lower shell 23 are made of ABS plastic material, and the surface is painted and brushed to enhance the aesthetics and wear resistance of the bracket 2.

[0043] Rotating member 3 is connected to the outer surface of lower shell 23 of bracket 2. Lower shell 23 is recessed toward upper shell 22 at the position corresponding to rotating member 3 to form a storage space. When bracket 2 rotates relative to main body 1 to form a storage position, rotating member 3 is stored in this storage space. The provision of the storage space prevents interference between rotating member 3 and bracket 2 during rotation and reduces the overall size of bracket 2 in the stored state.

[0044] Please refer to Figure 8 again. In an optional embodiment, the host body 1 includes a lower shell 13 and an upper shell 12 that are relatively arranged. The lower shell 13 and the upper shell 12 are assembled to form the internal space of the host body 1; the top surface of the upper shell 12 is bent upward on the side close to the display screen to form a blocking surface 122, and the other side is bent downward to form a mounting surface 123 with multiple interfaces. The blocking surface 122 is used to limit and stop the smart terminal device placed in the mounting position. Optionally, the rotating part 3 is arranged on the edge of one side of the upper shell 12 close to the mounting surface 123, and the size and shape of the bracket part 2 are respectively adapted to the size and shape of the top surface of the upper shell 12. The material of the host body 1 is usually selected to be consistent with the material of the bracket part. In this embodiment, the material of the upper shell 12 and the lower shell 13 is also ABS plastic material, and the surface is painted and brushed.

[0045] In an optional embodiment, the rotating member 3 includes a rotating shaft arm 31 fixedly connected to the bracket member 2, a central shaft 32 fixedly connected to the rotating shaft arm 31, and a fixing base 33 for setting the central shaft 32; the fixing base 33 is set on the side of the upper surface of the host body 1 away from the display screen 11, the central shaft 32 is movably connected to the fixing base 33, and can rotate relative to the fixing base 33, the fixing base 33 includes two parallel fixed frames, and the central shaft 32 is set between the two fixed frames. Specifically, a first through hole and a second through hole are respectively provided at both ends of the rotating shaft arm 31. The first through hole is used to pass the central shaft 32 to connect the rotating shaft arm 31 and the central shaft 32. The second through hole is used to pass a connecting member connected to the lower shell 23 of the bracket member 2. The connecting member can be a bolt, which is convenient to install and easy to replace. In this embodiment, the fixing seat 33 is arranged on the side of the upper surface of the host body 1 away from the display screen 11, so that when the bracket member 2 is rotated relative to the host body 1 to form a bracket state, the inner side of the bracket member 2 and the display screen 11 both face the user. In this way, when the smart terminal device is placed against the inner side of the bracket member 2, it can be ensured that the orientation of the smart terminal device and the display screen 11 is basically the same, both facing the user, which is convenient for the user to observe while driving.

[0046] Referring again to FIG. 6 , the host body 1 is provided with a first PCB board 14 and a second PCB board 15. The first PCB board 14 is provided with a first interface 141 for connecting to an external vehicle camera and a second interface 142 for communicating with a smart terminal device. The first interface 141 may be a FAKRA interface, and the second interface 142 may be a Type-C data transmission interface. Specifically, the external vehicle camera communicates with the controller via the FAKRA interface, and the smart terminal device communicates with the controller via the Type-C data transmission interface. The second PCB board 15 is provided with a data storage card slot 151 and a third interface for connecting to a GPS sensor. The third interface may be a mini-USB interface. The data storage card slot 151 is used to insert a memory card for real-time recording, driving recorder functionality, or firmware upgrades. The data storage card slot 151 may be a TF card slot. The GPS sensor and the controller communicate via the mini-USB interface, transmitting data collected by the GPS sensor to the controller.

[0047] In an optional embodiment, a first support plate 16 and a second support plate 17 are spaced apart within the host body 1, and the first PCB board 14 and the second PCB board 15 are respectively disposed on the first support plate 16 and the second support plate 17; a fixed side plate 18 is disposed between the first support plate 16 and the second support plate 17, and is fastened to the first support plate 16 and the second support plate 17. Specifically, the first PCB board 14 is disposed above the first support plate 16, the first support plate 16 is disposed above the second support plate 17, and the second PCB board 15 is disposed between the first support plate 16 and the second support plate 17. The first support plate 16, the second support plate 17, and the upper housing 12 are fastened together by bolts. Furthermore, the fixed side plate 18 is a T-shaped structure, with the bottom of the fixed side plate 18 fastened to the second support plate 17 by a snap-fit ​​connection, the upper middle portion of the fixed side plate 18 fastened to the first support plate 16 by bolts, and the upper surface of the fixed side plate 18 abuts against the first PCB board 14. Optionally, the surfaces of the first support plate 16 and the second support plate 17 are mirror polished to reduce the roughness of the contact surface with the PCB board. After the mirror polishing treatment, an insulating paint coating treatment is performed to avoid the occurrence of short circuit of the PCB board.

[0048] In an optional embodiment, a rubber pad 19 is provided at the connection between the FAKRA interface 141 and the housing of the host body 1. The provision of the rubber pad 19 facilitates the connection between the FAKRA interface 141 and the vehicle-mounted camera and provides a cushioning and shock-absorbing effect. In one specific example, the rubber pad 19 is made of a rubber material with a hardness of 50.

[0049] In an optional embodiment, the controller is communicatively connected to a vehicle-mounted dual-light camera equipped with a dual-light core. The controller generates different types of vehicle-mounted images based on the visible light image data and infrared image data collected by the vehicle-mounted dual-light camera. The types of vehicle-mounted images include at least infrared vehicle-mounted images and visible light vehicle-mounted images. The host body displays the vehicle-mounted images as a first target type, and the smart terminal displays the vehicle-mounted images as a second target type. The first target type and the second target type are the same or different. The vehicle-mounted dual-light camera can be a whole formed by integrating a visible light camera and an infrared camera. The vehicle-mounted dual-light camera can simultaneously collect infrared and visible light signals within the vehicle driving scene, and obtain visible light image data and infrared image data accordingly through the dual-light core using photoelectric conversion and imaging processing. The vehicle-mounted driver assistance system establishes a communication connection between the host body 1 and the smart terminal device, utilizing data exchange between the host body 1 and the smart terminal to provide a dual-screen display. Thus, the infrared vehicle image and the visible light vehicle image, respectively formed by the visible light image data and infrared image data collected by the vehicle-mounted dual-light camera, can be displayed on one of the display screens 11 of the host body 1 and the smart terminal, while the other simultaneously displays the visible light vehicle image. The first target type and the second target type can be default settings, such as the default setting that the first target type displayed by the host body 1 for the vehicle image is the infrared vehicle image, and the second target type displayed by the smart terminal device for the vehicle image is the visible light vehicle image. It should be noted that the size of the display screen 11 of the host body 1 is often fixed. The vehicle-mounted assisted driving instrument provides dual-screen display by establishing a communication connection between the host body 1 and the smart terminal device. It can also be to expand the display requirements of providing larger-sized vehicle-mounted image screens through the smart terminal device. The first target type for displaying the vehicle-mounted image on the display screen 11 of the host body 1 and the second target type for displaying the vehicle-mounted image on the smart terminal device can be manually selected by the user to synchronously display the same type of vehicle-mounted images.

[0050] In an optional embodiment, the vehicle-mounted dual-light camera also includes an imu sensor and a gps sensor provided on the dual-light core, and the imu sensor and gps are used to collaboratively obtain the real-time speed / position information of the vehicle and send it to the controller.

[0051] It should be further explained that the upper surface of the host body 1 is mounted with a corrugated plate, and the smart terminal device is placed vertically within the concave corrugated grooves of the corrugated plate. When placing the smart terminal device, the smart terminal device can be placed in different corrugated grooves according to actual conditions to adjust the placement angle of the smart terminal device, making it easier for the driver to view the image information displayed by the smart terminal device. Optionally, the lower surface of the host body 1 is provided with a 3M adhesive layer for fixing the in-vehicle driver assistance device inside the vehicle.

[0052] In an optional embodiment, the host body 1 is further equipped with a light sensor. A window for light to pass through is provided on the housing of the host body 1 at a position corresponding to the light sensor. The light sensor senses a light intensity signal and transmits it to the controller. Based on the light intensity signal, the controller controls the display screen 11 on the host body 1 to switch between displaying the white light vehicle image and the infrared vehicle image. The host body can obtain real-time light intensity information in the current environment through the light sensor, determine whether the current light is sufficient or dim, and adaptively control the type of vehicle image displayed on the host body 1 and the smart terminal based on this environmental information.

[0053] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this invention should be included in the scope of protection of the present invention. The scope of protection of the present invention should be based on the scope of protection of the claims.
