Description

Technical Field

[0001] The utility model relates to a vehicle vision system, in particular to a vehicle electronic rearview mirror system. Background Art

[0002] Based on considerations of vehicle driving safety, regulations stipulate the installation of indirect vision devices on vehicles. Generally, a central rearview mirror is installed inside the windshield of a vehicle, and side rearview mirrors are installed on both sides outside the vehicle to facilitate the driver to observe the rear view when driving the vehicle, avoiding collisions when the vehicle is reversing or changing lanes and affecting driving safety. In addition to the aforementioned two types, there are also distinctions such as interior rearview mirrors and exterior rearview mirrors. Traditional vehicle rearview mirrors provide the driver or passenger with a rear view or other views that cannot be directly seen through mirror reflection, with advantages such as simplicity, reliability, convenient installation, and low cost, but there is a risk of blind spots. With the increasing requirements for road safety and the popularization of electronic technologies, recently, electronic rearview mirrors (or digital virtual rearview mirrors) that display real-time images captured by cameras on a screen have been developed to replace traditional rearview mirrors. In addition to avoiding the visual occlusion of vehicle structures or interior personnel and objects and providing a wider field of view assistance, electronic rearview mirrors can also be combined with technologies such as radar or other sensing technologies to provide more diverse driving assistance functions.

[0003] Known vehicle side electronic rearview mirrors can be found in Chinese Patent Publication No. CN 101808853A, Chinese Patent Bulletin No. CN 108621937B, and European Patent Publication No. EP 3674140A1. Generally, a vehicle side electronic rearview mirror includes a camera installed outside the vehicle and a display screen installed inside the vehicle, and the display screen is usually installed on the A-pillar inside the vehicle (there are also those installed on the door). For driving and the vehicle itself, due to the distinction between the left and right sides, there are usually a left-side electronic rearview mirror and a right-side electronic rearview mirror, which are respectively installed on the left and right sides and are used to display the rear views on the left and right sides. Based on the different installation positions of the left and right side electronic rearview mirrors and the images of different cameras they display, they are different hardware components. That is, the left-side electronic rearview mirror is a set of hardware, and the right-side electronic rearview mirror is another set of hardware different from the left-side electronic rearview mirror.

[0004] When the left and right side electronic rearview mirrors are different hardware, for appearance or structure, different designs may be adopted, resulting in a burden on production, such as the need for corresponding molds, materials, and production lines, etc.; in terms of electronics, different signal connections or software and firmware considerations are also required. In addition, when assembling the vehicle, the production line personnel or robotic arms performing the installation also need to pay attention to the corresponding installation, such as installing the display screen of the left-side electronic rearview mirror on the left A-pillar and the display screen of the right-side electronic rearview mirror on the right A-pillar. In this way, the overall cost increases, which is not conducive to mass production. Summary of the Invention

[0005] The main object of the present utility model is to solve the problem that the conventional vehicle side electronic rearview mirrors need to be specially designed, produced, and distinguished between the left and right electronic rearview mirrors.

[0006] To achieve the above object, the present utility model provides a vehicle-mounted vision system, which includes two A-pillar displays, a first side rearview camera, a second side rearview camera, and a detection module. The two A-pillar displays are respectively arranged on a first A-pillar and a second A-pillar inside a vehicle equipped with the vehicle-mounted vision system. The first side rearview camera and the second side rearview camera are arranged on the vehicle, and the first side rearview camera and the second side rearview camera at least partially observe a first side rear area and a second side rear area of the vehicle. The detection module is coupled to the A-pillar displays, the first side rearview camera, and the second side rearview camera, and the detection module receives images from the first side rearview camera and the second side rearview camera. Wherein, the detection module determines whether the A-pillar display is installed on the first A-pillar or the second A-pillar, and thus outputs the image of the first side rearview camera to the A-pillar display installed on the first A-pillar, and outputs the image of the second side rearview camera to the A-pillar display installed on the second A-pillar.

[0007] In an embodiment, the detection module includes two detection units, which are respectively arranged on the A-pillar displays. Each detection unit has a detection element and a controller coupled to the detection element. The detection element detects and determines whether the A-pillar display is installed on the first A-pillar or the second A-pillar, and the controller determines the output of the image according to a determination result of the detection element.

[0008] In an embodiment, the A-pillar display includes a housing and a display panel installed on the housing. The housing has an installation portion, and the A-pillar display is fixed to the first A-pillar or the second A-pillar through the installation portion by connecting to a connecting member.

[0009] In an embodiment, the A-pillar display includes a first A-pillar display and a second A-pillar display. The detection module includes a first detection unit, a second detection unit, and a controller. The first detection unit and the second detection unit are respectively arranged on the first A-pillar display and the second A-pillar display. The first detection unit and the second detection unit respectively include a detection element coupled to the controller. Wherein, the detection element detects and determines whether the A-pillar display is installed on the first A-pillar or the second A-pillar, and the controller determines the output of the image according to a determination result of the detection element.

[0010] In one embodiment, if the detection element determines that the first A-pillar display is mounted on the first A-pillar, the controller transmits the image of the first side rearview camera for display on the first A-pillar display.

[0011] In one embodiment, the detection module has a first trigger element, a second trigger element, and a detector. The first trigger element and the second trigger element are disposed on the mounting portion and are alternatively triggered by the connecting member. The detector determines whether the A-pillar display is mounted on the first A-pillar or the second A-pillar according to whether the connecting member triggers the first trigger element or the second trigger element.

[0012] In one embodiment, the two A-pillar displays are the same.

[0013] In one embodiment, the geometric shape of the A-pillar display extends along a longitudinal central axis respectively, and each includes a display portion, a display area formed on the display portion, and a frame surrounding the periphery of the display area. The display area and the frame of the A-pillar display are axisymmetric with respect to the longitudinal central axis.

[0014] In one embodiment, the geometric shape of the A-pillar display extends along a longitudinal central axis respectively, and each includes a display portion, a display area formed on the display portion, and a frame surrounding the periphery of the display area. The frame includes a first side portion and a second side portion opposite to the first side portion. The front geometric shape of the first side portion and the second side portion is axisymmetric with respect to the longitudinal central axis.

[0015] In one embodiment, the geometric shape of the A-pillar display extends along a longitudinal central axis respectively, and each includes a display portion, a display area formed on the display portion, and a frame surrounding the periphery of the display area. The frame includes a first side portion and a second side portion opposite to the first side portion. The first side portion and the second side portion have a first gap and a second gap in the transverse direction with respect to the display area. The front geometric shape of the display area is axisymmetric with respect to the longitudinal central axis, and the first gap is equal to the second gap. Description of the Drawings

[0082] The terms used in this article are only for the purpose of describing specific embodiments and do not limit the present utility model. Unless otherwise specified in the context, the singular forms "a" and "the" used herein may also include the plural forms.

[0083] The directional terms used in this article, such as up, down, left, right, front, rear and their derivatives or synonyms, refer to the orientation of the elements in the drawings and do not limit the present utility model, unless otherwise clearly stated in the context.

[0084] Refer to Figure 1 、 Figure 2 and Figure 3 According to [[reference documents not provided]], the present utility model discloses an in-vehicle vision system mounted on a vehicle 90. The in-vehicle vision system includes a first side rearview camera 10, a second side rearview camera 20, a first A-pillar display 30, a second A-pillar display 40 and a detection module 50.

[0085] The first side rearview camera 10 and the second side rearview camera 20 are respectively disposed on the vehicle 90. In this embodiment, the first side rearview camera 10 and the second side rearview camera 20 are disposed outside the vehicle 90 and are respectively located on a first side 90a and a second side 90b of the vehicle 90, for at least partially observing a rear area 90c of the first side and a rear area 90d of the second side of the vehicle 90. In an example, the first side rearview camera 10 and the second side rearview camera 20 are disposed at positions on the first side 90a and the second side 90b close to the front (driver's seat, co-driver's seat) of the vehicle 90, and the rear area 90c of the first side and the rear area 90d of the second side can be defined as the areas behind the first side rearview camera 10 and the second side rearview camera 20, rather than only referring to the rear side of the vehicle 90.

[0086] The first A-pillar display 30 is disposed on a first A-pillar 91 inside the vehicle 90, and the second A-pillar display 40 is disposed on a second A-pillar 92 inside the vehicle 90. In one example, the first A-pillar 91 is close to the driver's seat, and the second A-pillar 92 is close to the co-driver's seat. In different examples, the configuration may be opposite. In the present utility model, the first A-pillar display 30 and the second A-pillar display 40 are the same A-pillar display, and the difference between the two may be only the installation position. In some examples, the first A-pillar display 30 and the second A-pillar display 40 being the same A-pillar display means having the same structure and electronic design, or may mean that the first A-pillar display 30 and the second A-pillar display 40 are produced and manufactured according to the same specifications on the same production line.

[0087] The detection module 50 is coupled to the first side rearview camera 10, the second side rearview camera 20, the first A-pillar display 30, and the second A-pillar display 40. The detection module 50 receives a first image recorded by the first side rearview camera 10 and a second image recorded by the second side rearview camera 20, and respectively displays the first image and the second image on the first A-pillar display 30 and the second A-pillar display 40. In one example, the first image may be a real-time image of the first side rear area 90c, and the second image may be a real-time image of the second side rear area 90d.

[0088] The detection module 50 includes a first detection unit 51 and a second detection unit 52. The first detection unit 51 has a detection element 511 and a controller 512. The controller 512 is coupled to the detection element 511. The second detection unit 52 has a detection element 521 and a controller 522. The controller 522 is coupled to the detection element 521. The first detection unit 51 is disposed on the first A-pillar display 30, and the second detection unit 52 is disposed on the second A-pillar display 40.

[0089] Refer to Figure 4 and Figure 5 , in another embodiment, the detection module 50 includes a first detection unit 53, a second detection unit 54, and a controller 55. The first detection unit 53 has a detection element 531. The second detection unit 54 has a detection element 541. The controller 55 is coupled to the detection elements 531, 541. The first detection unit 53 is disposed on the first A-pillar display 30, and the second detection unit 54 is disposed on the second A-pillar display 40.

[0090] Refer to Figure 6 and Figure 7, the first A-pillar display 30 and the second A-pillar display 40 can be the same A-pillar display 60. That is, the in-vehicle vision system of the present utility model includes two identical A-pillar displays 60. The A-pillar display 60 includes a housing 61 and a display panel 62. The display panel 62 is installed on the housing 61. The housing 61 has a mounting portion 611. The first A-pillar 91 and the second A-pillar 92 are respectively provided with a connecting member (not shown in the figure). The A-pillar display 60 is connected to the connecting member via the mounting portion 611. In one example, the connecting member is a cantilever.

[0091] When the first A-pillar display 30 and the second A-pillar display 40 are the same A-pillar display 60, it means that the A-pillar display 60 can be installed on the first A-pillar 91 as the first A-pillar display 30, or can be installed on the second A-pillar 92 as the second A-pillar display 40. Therefore, whether it is the appearance, structure or electronic design, the same (single) design can be adopted. In addition, the production line personnel or robotic arm performing the installation do not need to pay attention to which A-pillar display is to be installed on the first A-pillar 91 and the second A-pillar 92, and only need to take the single and unique A-pillar display 60. However, the problem to be solved is that when the A-pillar display 60 is installed on the A-pillar, the A-pillar display 60 does not know whether the installed position is on the first A-pillar 91 or the second A-pillar 92, that is, on the left or right side, and thus does not know whether to output the left or right side picture or perform related image processing.

[0092] The present utility model utilizes the arrangement of the detection module 50 and its cooperation with the A-pillar display 60 to solve this problem. The detection module 50 is disposed within the A-pillar display 60, and the detection module 50 includes a first trigger element 50a, a second trigger element 50b, and a detector 50c. The first trigger element 50a and the second trigger element 50b are disposed on the mounting portion 611 and are alternatively triggered by the connecting member. The detector 50c determines whether the A-pillar display 60 is mounted on the first A-pillar 91 or the second A-pillar 92 according to whether the connecting member triggers the first trigger element 50a or the second trigger element 50b. In an example, when the first trigger element 50a is triggered, it represents that the A-pillar display 60 is disposed on the first A-pillar 91 and can be regarded as the first A-pillar display 30. The detection module 50 outputs the first image of the first side rearview camera 10 to the first A-pillar display 30. When the second trigger element 50b is triggered, it represents that the A-pillar display 60 is disposed on the second A-pillar 92 and can be regarded as the second A-pillar display 40. The detection module 50 outputs the second image of the second side rearview camera 20 to the second A-pillar display 40. Among them, the controller 55 (or the controller 512, the controller 522) of the detection module 50 determines whether to output the first image or the second image according to a judgment result of the detection elements 531, 541 (or the detection elements 511, 521).

[0093] Referring to Figure 8 , in an embodiment of the present utility model, geometric shapes of the first A-pillar display 30 and the second A-pillar display 40 respectively extend along a longitudinal central axis 30a, 40a. The first A-pillar display 30 includes a display portion 31 and a frame 32. The display portion 31 forms a display area 31a, and the frame 32 is disposed around an outer periphery of the display area 31a. The second A-pillar display 40 includes a display portion 41 and a frame 42. The display portion 41 forms a display area 41a, and the frame 42 is disposed around an outer periphery of the display area 41a.

[0094] In this embodiment, the display area 31a and the frame 32 of the first A-pillar display 30 are axisymmetric with respect to the longitudinal central axis 30a, and the display area 41a and the frame 42 of the second A-pillar display 40 are axisymmetric with respect to the longitudinal central axis 40a. It can be understood that the display portion 31 of the first A-pillar display 30 and the display portion 41 of the second A-pillar display 40 can be the same components, and the frame 32 of the first A-pillar display 30 and the frame 42 of the second A-pillar display 40 can also be the same components, and can be quickly produced on the same production line.

[0095] In one example, the border 32 includes a first side portion 32a and a second side portion 32b. The first side portion 32a is located on the side close to the first side rear-view camera 10. The second side portion 32b is disposed opposite to the first side portion 32a. The first side portion 32a has a first gap 32c with the display area 31a in the transverse direction. The second side portion 32b has a second gap 32d with the display area 31a in the transverse direction. The front geometry of the first side portion 32a and the second side portion 32b is axisymmetric with respect to the longitudinal central axis 30a, and the first gap 32c is substantially equal to the second gap 32d, that is, the first gap 32c and the second gap 32d have the same length, width, and depth.

[0096] Similarly, the border 42 includes a first side portion 42a and a second side portion 42b. The first side portion 42a is located on the side close to the second side rear-view camera 20. The second side portion 42b is disposed opposite to the first side portion 42a. The first side portion 42a has a first gap 42c with the display area 41a in the transverse direction. The second side portion 42b has a second gap 42d with the display area 41a in the transverse direction. The front geometry of the first side portion 42a and the second side portion 42b is axisymmetric with respect to the longitudinal central axis 40a, and the first gap 42c is substantially equal to the second gap 42d, that is, the first gap 42c and the second gap 42d have the same length, width, and depth.

[0097] Referring to Figure 9 , in another embodiment of the present invention, the first side portion 32a and the second side portion 32b of the border 32 are not axisymmetric with respect to the longitudinal central axis 30a, and the upper portion 32e and the lower portion 32f of the border 32 are axisymmetric with respect to the transverse central axis 30b of the first A-pillar display 30. In this embodiment, the border 32 includes a first side frame 321 located at the first side portion 32a and a second side frame 322 located at the second side portion 32b, and the width of the first side frame 321 is greater than the width of the second side frame 322.

[0098] The first side portion 42a and the second side portion 42b of the border 42 are not axisymmetric with respect to the longitudinal central axis 40a, and the upper portion 42e and the lower portion 42f of the border 42 are axisymmetric with respect to the transverse central axis 40b of the second A-pillar display 40. In this embodiment, the border 42 includes a first side frame 421 located at the first side portion 42a and a second side frame 422 located at the second side portion 42b, and the width of the first side frame 421 is greater than the width of the second side frame 422.

[0099] In this embodiment, the width of the first side frame 321 is the same as the width of the first side frame 421, and the width of the second side frame 322 is the same as the width of the second side frame 422. Accordingly, even if the first side portions 32a, 42a and the second side portions 32b, 42b of the frames 32, 42 are not axisymmetric with respect to the longitudinal central axes 30a, 40a, the frame 32 can be the same as the frame 42 after being rotated 180°. Therefore, the frames 32, 42 can be regarded as the same components and produced on the same production line.

[0100] In summary, through the detection module provided in the A-pillar display of the present utility model, any one of the first trigger element and the second trigger element can be triggered when installed on the connecting member to determine whether the A-pillar display is installed on the first A-pillar or the second A-pillar to serve as the first A-pillar display or the second A-pillar display. In another embodiment, the first A-pillar display and the second A-pillar display are designed to be axisymmetric with respect to the longitudinal central axis respectively and can be regarded as the same components to be produced on the same production line. In another embodiment, the frame of the first A-pillar display can be the same as the frame of the second A-pillar display after rotation, so it can also be regarded as the same component and produced on the same production line, thereby reducing the production cost.
