Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an intelligent composite vehicle rearview mirror system. Background Technology

[0002] As a crucial component of automotive safety systems, the performance of rearview mirrors directly impacts driving safety. Traditional exterior rearview mirrors employ a single-curvature spherical mirror structure, utilizing the principle of physical optical reflection to achieve rearward visibility. However, their basic architecture has gradually revealed various technical limitations when dealing with complex traffic environments.

[0003] In terms of optical performance, traditional rearview mirrors have significant blind spots due to their fixed curvature design. These blind spots cover critical areas of adjacent lanes, making it difficult for drivers to directly observe vehicles to the side and rear when changing lanes or turning. Existing improvements often rely on frequent head turns by the driver or the addition of auxiliary devices; however, the former affects driving focus, and the latter easily causes visual information interference. Although some vehicles employ electronic assistance systems, their practicality is still limited by problems such as high false alarm rates and delayed information feedback.

[0004] Regarding environmental adaptability, traditional mirror reflection mechanisms have the following drawbacks: 1) Severe glare from following vehicles' high beams during nighttime driving, especially in rainy or foggy weather, significantly reducing visibility; 2) Rapid fogging of the mirror in low-temperature and high-humidity environments, with traditional defogging solutions exhibiting response delays; 3) Residue on the mirror affects image clarity in rainy or snowy weather. While existing electronic improvement solutions attempt to integrate sensor modules, they often disrupt the original structure of the rearview mirror or reduce the effective viewing area of ​​the mirror.

[0005] The existing technical solutions have two main contradictions: mechanical rearview mirrors are difficult to be compatible with modern electronic sensing technology, while purely electronic solutions cannot retain reliable optical observation functions.

[0006] Especially when the system power supply is abnormal, the failure of electronic devices may cause a safety hazard of completely losing the ability to see behind.

[0007] These technological shortcomings lead to multiple operational burdens for drivers in complex road conditions: they must process information reflected by traditional mirrors while also responding to interactive feedback from electronic devices. This multitasking mode easily causes distraction. Studies have shown that such operational loads can significantly prolong the driver's reaction time, directly impacting driving safety in high-speed driving scenarios. Therefore, developing a new rearview mirror system that balances the reliability of optical observation, the accuracy of electronic perception, and environmental adaptability has become a key research direction for improving vehicle active safety technologies.

[0009] To achieve the above objectives, this utility model provides the following solution:

[0010] A smart composite vehicle rearview mirror system, comprising:

The camera module has a high-resolution image sensor and a dual filter switching mechanism, and is configured to automatically switch imaging parameters between daytime mode and nighttime mode.

[0020] In one exemplary embodiment, the camera module integrates an infrared fill light component, the intensity of which and the beam angle can be dynamically adjusted according to environmental conditions.

[0021] In one exemplary embodiment, the temperature control system has a heating power adjustment module based on a closed-loop control algorithm, configured to maintain the mirror temperature to suppress fogging.

[0023] In one exemplary embodiment, the image processing unit executes a multi-scale brightness compensation algorithm and an edge enhancement algorithm to perform real-time image optimization processing on the input video stream.

[0024] In one exemplary embodiment, the control motherboard layer also integrates a fail-safe module, which, when an abnormality is detected in the display screen layer, cuts off the electronic display function and activates the optical protection mechanism, forcibly switching to a pure physical reflection mode.

[0033] The purpose of this invention is to provide an intelligent composite vehicle rearview mirror system to solve the problems existing in the prior art and realize the coordinated operation of physical reflection and electronic display.

[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Please refer to Figure 1 This embodiment provides an intelligent composite vehicle rearview mirror system, including a rearview mirror housing 7 and a mirror support plate 6. The mirror support plate 6 is mounted on the rearview mirror housing 7. A single-sided mirror layer 1, a heating film layer 2, a display screen layer 3, and a control board layer 4, which are stacked together, are mounted on the mirror support plate 6. The inner surface of the single-sided mirror layer 1 is coated with a semi-transparent and semi-reflective optical film system; the heating film layer 2 has a transparent conductive layer, and the mirror surface temperature is regulated by a temperature control system; the display screen layer 3 is signal-connected to the control board layer 4, and the display screen layer 3 is configured to display electronic images through the single-sided mirror layer 1; the control board layer 4 integrates an image processing unit, an environmental perception module, and mode control logic, and can switch between physical reflection mode and electronic display mode.

[0036] The semi-transparent and semi-reflective optical film system includes a semi-transparent and semi-reflective interference film and an anti-glare coating arranged sequentially from the outside to the inside.

[0037] Specifically, the single-sided mirror layer 1 uses a high-transmittance glass substrate, and its inner surface is sequentially coated with:

[0038] Anti-glare coating, using gradient refractive index material to suppress internal reflection;

[0039] The semi-transparent and semi-reflective interference film has a transmittance to reflectance ratio ranging from 1:1.8 to 2.5, such as 33% transmittance and 65% reflectance.

[0040] The single-sided mirror layer 1 has a dual function: serving as a traditional reflective mirror and as an optical light guide layer for the display screen layer 3, enabling the transmission display of electronic images.

[0041] A microprism array is embedded in the display layer 3 to correct image displacement caused by mirror refraction and ensure spatial consistency between the electronic image and the physical reflection image.

[0042] The heating film layer 2 has a transparent conductive film, which, together with the temperature sensor, forms a closed-loop control system configured to adjust the heating power in response to changes in ambient temperature. A micron-level linewidth ITO conductive mesh is preferably used to achieve rapid and uniform heating while ensuring sufficient light transmittance.

[0043] The temperature control system has a heating power adjustment module based on a closed-loop control algorithm, configured to maintain the mirror temperature to suppress fogging.

[0044] The mirror support plate 6 has heat dissipation holes 9, and the rearview mirror housing 7 has heat dissipation channels. The heat from the display screen is dissipated to one side of the rearview mirror housing 7 through the heat dissipation holes 9, and then dissipated to the outside through the heat dissipation channels.

[0045] Display layer 3 features a dynamic backlight compensation module configured to adaptively adjust display brightness and contrast based on ambient light levels. A wide color gamut IPS panel is preferably used, seamlessly bonded to the single-sided mirror layer 1 via optical adhesive, with a pixel pitch ≤0.08mm to ensure image sharpness.

[0046] A camera module 5, which is connected to the display screen layer 3 and the control motherboard layer 4, is also installed on the mirror support plate 6. Camera holes 8 are provided at the positions corresponding to the camera module 5 on the single-sided mirror layer 1, the heating film layer 2, and the display screen layer 3. The camera module 5 has a high-resolution image sensor and a dual-filter switching mechanism, configured to automatically switch imaging parameters between daytime and nighttime modes.

[0047] The camera module 5 integrates an infrared fill light component, whose light intensity and beam angle can be dynamically adjusted according to environmental conditions.

[0048] The control motherboard layer 4 integrates a multi-core processor to implement three major functional modules:

[0049] The image processing engine has the capability for real-time processing at 4K@30fps;

[0050] The environmental sensing unit supports the fusion sensing of multiple parameters, including illuminance, temperature, and humidity.

[0051] The security monitoring module diagnoses the system's health status in real time.

[0052] The mode control logic includes an intelligent mode switching function that is linked to the vehicle's steering signal, and the corresponding side electronic image can be dynamically superimposed on the display layer 3.

[0053] The image processing unit executes multi-scale brightness compensation algorithms and edge enhancement algorithms to perform real-time image optimization processing on the input video stream.

[0054] The control motherboard layer 4 also integrates a fail-safe module. When an abnormality is detected in the display layer 3, the electronic display function is cut off and the optical protection mechanism is activated, forcibly switching to a pure physical reflection mode.

[0055] The intelligent control logic in this embodiment is as follows:

[0056] Physical reflection priority mode: In system standby mode, only basic reflection function is maintained, and power consumption is <1W;

[0057] Enhanced display mode: When a turn signal, blind spot object, or sudden change in ambient light is detected, the corresponding side electronic display is automatically activated. The screen transparency is dynamically adjusted according to the vehicle speed. For example, when the vehicle speed is >80km / h, the transparency is set to 50% to avoid distraction.

[0058] Environment Adaptive Mode:

[0059] Rain and snow mode: Activate heating film layer 2 to maintain mirror temperature (60℃) and prevent fogging;

[0060] Night mode: The IR-CUT filter switches to black and white imaging, and infrared fill light enhances the image to avoid glare from the high beams of vehicles behind.

[0061] In addition, this embodiment can also integrate human factors engineering optimization programs:

[0062] Visual load control: The driver's gaze point is monitored by an eye-tracking module (integrated into the edge of the rearview mirror). When the driver's gaze is continuously fixed on the electronic screen for more than 2 seconds, the screen brightness is automatically reduced and a warning sound is issued.

[0063] Attention guidance mechanism: Use edge highlighting and motion prediction lines to identify potential risk targets in electronic images.

[0064] It should be noted that the execution units and control modules that implement the control logic of this embodiment are all existing technologies.

[0065] This invention achieves deep coupling between physical reflection and electronic display through optical coating technology, combined with an environmental adaptive control algorithm, significantly expanding functional boundaries while retaining the reliability of traditional rearview mirrors. Its composite design provides a multimodal perception-display integrated solution for vehicle safety systems, possessing outstanding practical value and market prospects.
