Description

Technical Field

[0001] This disclosure relates to a vehicle monitoring technology, and more particularly to an electronic rearview mirror warning device. Background Technology

[0002] Most vehicles are now equipped with blind spot detection (BSD) systems. These systems are typically mounted on the rearview mirrors and work by detecting images behind the mirror to help drivers detect objects on the sides of the vehicle.

As a result, drivers are unaware of blind spots in front of the vehicle, creating a driving hazard.

[0003] Therefore, there is an urgent need for a vehicle monitoring and warning system to solve the problems existing in the above-mentioned technologies. Utility Model Content

[0004] Therefore, one objective of this disclosure is to provide an electronic rearview mirror warning device whose processor can receive side images of the front wheels on both sides of a vehicle captured by a camera, and can perform image recognition processing on these side images using a texture and image feature database built into the processor. This allows the processor to obtain information on road conditions, such as whether the expected driving range of the vehicle is a drivable road and whether there are obstacles. Based on the road condition information, the processor can control the display device to emit a warning image and / or a warning sound to remind the driver. The electronic rearview mirror warning device can actively detect driving conditions and remind the driver when there is a risk within the expected driving range, thus improving driving safety.

[0038] The embodiments of this disclosure are discussed in detail below. However, it will be understood that the embodiments provide many applicable concepts that can be implemented in a wide variety of specific situations. The discussed and disclosed embodiments are for illustrative purposes only and are not intended to limit the scope of this disclosure. All embodiments of this disclosure disclose a variety of different features, but these features may be implemented individually or in combination as needed.

[0039] In addition, the terms "first" and "second" used in this article do not specifically refer to order or sequence, but are only used to distinguish elements or operations described using the same technical terms.

[0040] The spatial relationship between the two elements described in this disclosure applies not only to the orientation shown in the accompanying drawings, but also to orientations not shown in the drawings, such as inverted orientations. Furthermore, the terms "connection," "electrical connection," or similar expressions used in this disclosure to refer to two components are not limited to a direct or electrical connection, but may also include indirect or electrical connections as needed.

[0041] Please refer to Figures 1 to 3 These are block diagrams illustrating an electronic rearview mirror warning device 100 according to an embodiment of the present disclosure, schematic diagrams showing the camera 200 of the electronic rearview mirror warning device 100 mounted on a vehicle 500, and schematic diagrams showing the electronic rearview mirror warning device 100 mounted on a vehicle 500. The electronic rearview mirror warning device 100 is used in general vehicles 500 such as cars, jeeps, pickup trucks, or vans. The electronic rearview mirror warning device 100 can provide the driver with information and warnings about road conditions in front of the vehicle 500 and beside the front wheels 510, thereby improving driving safety.

[0042] The electronic rearview mirror warning device 100 mainly includes two cameras 200, a processor 300, and a display device 400. The two cameras 200 are respectively mounted on both sides of the front 520 of the vehicle 500. For example, the two cameras 200 can be mounted on the left and right rearview mirrors 530 of the vehicle 500, respectively. Each camera 200 is configured to capture side images SI1 and SI2 of the front wheel 510 on the side of the vehicle 500 to which it is mounted. These side images SI1 and SI2 of the front wheel 510 cover both the area in front of and behind the front wheel 510. In some embodiments, the viewing angle α of each camera 200 is substantially 120 degrees, and the tilt angle β of each camera 200 towards the front 520 is substantially 20 degrees. For example, the viewing angle α of each camera 200 is from 60 degrees in front to 60 degrees behind the vehicle. In addition, the lens of each camera 200 is tilted 20 degrees outward toward the front of the vehicle 520, so that the framing direction of the camera 200 has a substantial tilt angle β of 20 degrees.

[0043] The processor 300 is located within the driver's cabin 540 of the vehicle 500. The processor 300 can be connected to the cameras 200 via wired or wireless transmission. This allows the processor 300 to receive side images SI1 and SI2 of the front wheels 510 of the vehicle 500 captured by the cameras 200. In this embodiment, the processor 300 stores textures and at least one first image feature for each of various road conditions, and at least one second image feature for each of various objects. Specifically, the processor 300 stores textures of drivable roads, such as flat grass, concrete, asphalt, and brick roads, and at least one first image feature for each. The processor 300 also stores textures and at least one first image feature for each of non-drivable roads, such as water, puddles, curbs, and medians. Furthermore, the processor 300 stores one or more second image features for objects such as people, animals, cars, motorcycles, bicycles, traffic cones, fire hydrants, and fences.

[0044] The processor 300 can further utilize the stored texture, first image features, and second image features to perform image recognition processing on the side images SI1 and SI2 of the front wheel 510. This allows for the use of, for example, artificial intelligence (AI) computation to compare and identify the texture and image features of the side images SI1 and SI2, thereby obtaining road condition information for the vehicle 500. For instance, when the processor 300 identifies the texture and image features of a pothole in the side images SI1 and SI2 of the front wheel 510, the processor 300 can further obtain road condition information based on the comparison results, indicating that a pothole exists within the expected driving range of the vehicle 500, classifying it as an impassable road. As another example, when the processor 300 identifies the texture and image features of a flat asphalt road in the side images SI1 and SI2 of the front wheel 510, but also identifies the image features of a child, the processor 300 can obtain road condition information based on the comparison results, indicating that there is an obstacle on a drivable road within the expected driving range of the vehicle 500. Therefore, the driving road condition information obtained by the processor 300 by recognizing the side images SI1 and SI2 of the front wheel 510 includes whether the expected driving range of the vehicle 500 is a drivable road and whether there is at least one obstacle within the driving range.

[0045] In some embodiments, the processor 300 connects to the turn signal control system of the vehicle 500 via wired or wireless transmission to obtain turning information of the vehicle 500. In other embodiments, the processor 300 connects to the steering wheel control system of the vehicle 500 via wired or wireless transmission to obtain accurate turning information of the vehicle 500. The processor 300 can combine road condition information with the turning information of the vehicle 500 to control the display device 400 to issue a warning signal.

[0046] Please refer to Figure 3and Figure 4 ,in Figure 4 This is a schematic diagram illustrating a display device 400 of an electronic rearview mirror warning device 100 according to an embodiment of the present disclosure. Figure 3 As shown, the display device 400 is disposed within the driver's cabin 540 of the vehicle 500 and can be signal-connected to the processor 300 via wired or wireless transmission. In some embodiments, the processor 300 may be disposed within the display device 400 and electrically connected to the display device 400 via physical wiring. The display device 400 can receive and display side images SI1 and SI2 from the two front wheels 510 of the processor 300. The display device 400 includes a screen 410 having a display area 412 for displaying the side images SI1 and SI2.

[0047] In some embodiments, such as Figure 3 As shown, the display device 400 is a rectangular device and is horizontally positioned within the driver's cockpit 540. Specifically, the screen 410 of the display device 400 has a rectangular display area 412, which extends horizontally along its length LD. Side images SI1 and SI2 are arranged along the length LD of the rectangular display area 412. That is, the side images SI1 and SI2 are arranged horizontally, which makes viewing more intuitive for the driver.

[0048] The display device 400 can also issue warning signals. Specifically, when the road condition information indicates a risk within the expected driving range of the vehicle 500, such as an impassable road or an obstacle, the processor 300 controls the display device 400 to issue a warning signal. For example, the display device 400 can issue a warning signal by flashing the side image SI1 or SI2 containing an obstacle or an impassable road. That is, when the processor 300 identifies an obstacle or an impassable road in the side image SI1, the processor 300 controls the display device 400 to display the side image SI1 in a flashing manner.

[0049] The screen 410 of the display device 400 may be, for example, a touch screen. Therefore, the screen 410 of the display device 400 can serve as a human-machine interface to facilitate the setting of the camera 200's shooting angle, the image recognition of the processor 300, and the display settings and warning settings of the display device 400.

[0050] In some embodiments, such as Figure 1As shown, the display device 400 may include a horn 420. The horn 420 can also be connected to the processor 300 via wired or wireless transmission. When the processor 300 determines that there is a risk within the driving range of the vehicle 500 based on the road condition information obtained from the side images SI1 and SI2, the processor 300 controls the horn 420 to emit a warning sound to alert the driver. For example, if the processor 300 determines that there is an obstacle to the left of the left front wheel 510 of the vehicle 500, and the turn signal control system or steering wheel control system determines that the vehicle 500 intends to turn left, in addition to controlling the display device 400 to flash the side image SI1, it can also control the horn 420 to emit a warning sound to enhance the warning effect.

[0051] As can be seen from the above embodiments, one advantage of this disclosure is that the processor of the electronic rearview mirror warning device can receive side images of the front wheels on both sides of the vehicle captured by the camera, and can perform image recognition processing on these side images using a texture and image feature database built into the processor. This allows it to obtain information about the road conditions, such as whether the expected driving range of the vehicle is a drivable road and whether there are obstacles. Based on the road condition information, the processor can control the display device to emit a warning image and / or a warning sound to remind the driver. The electronic rearview mirror warning device can actively detect driving conditions and remind the driver when there is a risk within the expected driving range, thus improving driving safety.

[0052] Although this disclosure has been provided above with reference to embodiments, it is not intended to limit this disclosure. Any person skilled in the art can make various changes and modifications without departing from the concept and scope of this disclosure. Therefore, the scope of protection of this disclosure shall be determined by the claims.
