Description

Technical Field

[0001] This invention relates to the field of vehicle cabin control technology, and more particularly to an automatic sun-shielding system for rear seats in automobiles. Background Technology

[0002] When passengers in the back of a car are riding in a car, they may encounter situations where the light is glaring (it may come from the windshield or the rear side windows). In the current technological scenario, the position adjustment of the rear seats requires the user to manually adjust them to a suitable position. This operation is not only cumbersome and inconvenient during driving, but also poses certain safety hazards. Summary of the Invention

[0003] In view of the above, the present invention aims to provide an automatic sun-shielding system for rear seats of automobiles to solve the aforementioned technical problems.

[0004] The technical solution adopted in this invention is as follows:

[0005] This invention provides an automatic sun-shielding system for rear seats of automobiles, including: a camera sensor, a zero-gravity seat controller, and a zero-gravity seat;

[0006] The camera sensor is used to detect the visual signal of sunlight shining on the eye area of ​​the rear passenger in real time when the automatic sun protection mode is enabled, and transmit the visual signal to the zero gravity seat controller.

[0007] The zero-gravity seat controller uses an image recognition algorithm to process the visual signals in order to track the position of the rear passenger's eye area and the sunlight exposure in real time.

[0008] The zero-gravity seat controller automatically adjusts the posture of the zero-gravity seat according to the position of the eye area and the sunlight exposure, including: changing the passenger posture by adjusting at least one parameter among the seat back angle, seat cushion tilt, leg support and overall sliding position, so that the passenger's eye area is deviated from the path of sunlight exposure.

[0009] In at least one of the possible implementations, the automatic light-avoidance system further includes a light sensor, which is used to detect the ambient light intensity and the angle of sunlight incidence inside the vehicle. After fusing the data with the data from the camera sensor, the zero-gravity seat controller calculates the relatively optimal seat adjustment parameters.

[0010] The relatively optimal seat adjustment parameters are calculated based on a predefined comfort model, which is defined by at least three indicators: passenger height, current sitting posture, and dynamic changes in sunlight.

[0011] In at least one of the possible implementations, the zero-gravity seat controller is also connected to the vehicle control system for acquiring vehicle driving status information;

[0012] Furthermore, when the vehicle is determined to be in a preset operating condition based on the vehicle driving status information, the zero-gravity seat controller will pause automatic light-shielding adjustment when the automatic light-shielding adjustment mode is enabled.

[0013] In at least one of the possible implementations, the automatic rear seat glare reduction system further includes a rear window adjustment component controlled by the vehicle control system to help reduce the impact of light on the eyes of rear passengers.

[0014] The rear window adjustment component includes at least one of the following: a sunshade and electrochromic glass.

[0015] In at least one of the possible implementations, the vehicle control system intelligently changes the state of the rear window adjustment component based on the angle of sunlight and vehicle driving status information, in coordination with the posture adjustment of the zero-gravity seat.

[0016] The posture adjustment of the coordinated zero-gravity seat, which intelligently changes the state of the rear window adjustment component, includes: prioritizing the adjustment of the zero-gravity seat, and after the seat is adjusted to a preset posture, predicting the illumination trend of light on the passenger's eyes in the current seat posture based on the angle of sunlight and vehicle driving status information, and intelligently activating the rear window adjustment component according to the illumination trend.

[0017] In at least one of the possible implementations, the intelligent start-up rear window adjustment component includes at least one of the following: adjusting the deployment speed of the sunshade and / or the color-changing response time of the electrochromic glass.

[0018] Compared with existing technologies, the main design concept of this invention lies in the overall system architecture, which consists of at least a camera sensor, a zero-gravity seat controller, and a zero-gravity seat. When the automatic glare-avoidance adjustment mode is activated, the camera sensor detects the visual signal of sunlight illuminating the eye area of ​​the rear passengers in real time and transmits it to the zero-gravity seat controller. The zero-gravity seat controller processes the visual signal using an image recognition algorithm to obtain the position of the rear passengers' eye area and the sunlight exposure in real time. Based on the eye area position and sunlight exposure, it automatically adjusts the posture of the zero-gravity seat to deviate the passenger's eye area from the path of sunlight. This invention addresses the problem of glare encountered by rear passengers by intelligently and automatically improving the convenience of glare-avoidance adjustment and avoiding safety hazards, thereby providing passengers with a better driving experience. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described below with reference to the accompanying drawings, wherein:

[0020] Figure 1 This is a schematic diagram of an automatic sun-shielding system for rear seats in a car, provided as an embodiment of the present invention. Detailed Implementation

[0021] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] This invention proposes an embodiment of an automatic sun-shielding system for rear seats in automobiles, specifically, as follows: Figure 1 As shown, it includes: a camera sensor, a zero-gravity seat controller, and a zero-gravity seat.

[0023] The camera sensor is installed in the rearview mirror, roof, or B-pillar of the vehicle. When the automatic sun-shielding mode is activated, it is used to detect the visual signal of sunlight shining on the eye area of ​​the rear passenger in real time and transmit the visual signal to the zero-gravity seat controller. The zero-gravity seat controller uses an image recognition algorithm to process the visual signal to track the position of the eye area of ​​the rear passenger and the sunlight exposure in real time. The image recognition algorithm includes at least a face detection module and an eye positioning module for recognizing the eye area illuminated by sunlight.

[0024] Regarding the automatic light-blocking mode, in actual operation, users can make their own decisions to enable or disable the automatic light-blocking mode as needed via voice, touch screen, or mobile device.

[0025] The zero-gravity seat controller automatically adjusts the posture of the zero-gravity seat according to the position of the eye area and the sunlight exposure, including: changing the passenger posture by adjusting at least one parameter among the seat back angle, seat cushion tilt, leg support and overall sliding position, so that the passenger's eye area is deviated from the path of sunlight exposure.

[0026] Two additional points can be added to the above embodiments:

[0027] Firstly, the zero-gravity seat controller can also record user preferences and historical adjustment data, and optimize the automatic light-blocking adjustment strategy through machine learning algorithms to provide a personalized comfort experience.

[0028] Secondly, the automatic sun-shielding system for the rear seats of the car also includes a light sensor. The light sensor is used to detect the ambient light intensity and the angle of sunlight incidence inside the vehicle, and to fuse the visual signal with the camera sensor to obtain the relatively optimal seat adjustment parameters. The optimal seat adjustment parameters are based on a predefined comfort model, which takes into account at least the target passenger's height, their sitting posture, and the current dynamic changes in sunlight.

[0029] In some preferred embodiments of the present invention, the automatic light-blocking system may further include a rear window adjustment component, which is controlled by the vehicle control system, such as the body controller, to help reduce the impact of light on the eyes of rear passengers. The rear window adjustment component mentioned herein includes at least one of a sunshade, electrochromic glass, or polarized glass. In actual control, the body controller can intelligently adjust the state of the rear window adjustment component based on the angle of sunlight and information such as the vehicle's location, time, speed, direction, and navigation, in coordination with the angle and posture of the zero-gravity seat, to optimize the light-blocking effect. The intelligent adjustment here can be reflected in the fact that the zero-gravity seat controller first adjusts the posture angle of the zero-gravity seat, and after the seat reaches the adjusted position (for example, it can be a position to keep the rear passenger's eyes away from the current incident light, or it can be adjusted to the limited position of the seat itself, at which point the passenger's eyes may not be completely out of the sunlight), it predicts the illumination trend of the light on the passenger's eyes in the current seat posture (the current illumination situation and the future changes of the incident light as the vehicle moves and time goes by), and intelligently activates the rear window adjustment component according to the illumination trend. For example, but not limited to adjusting the unfolding speed of the sunshade or the color-changing response time of the electrochromic glass, etc., so that it can be relatively synchronized with the zero-gravity seat adjustment to achieve a smooth transition of light-blocking effect.

[0030] Finally, it can be added that the zero-gravity seat controller is also connected to the vehicle control terminal to obtain vehicle driving status information, such as speed, yaw angle, pedal position, etc. In this way, when the vehicle is in a sharp turn, acceleration or braking situation, even if the automatic sunshade adjustment mode is currently activated, the zero-gravity seat controller will still pause the automatic sunshade adjustment to ensure passenger safety.

[0031] In summary, the main design concept of this invention lies in a system architecture comprising at least a camera sensor, a zero-gravity seat controller, and a zero-gravity seat. When the automatic glare-avoidance adjustment mode is activated, the camera sensor detects the visual signal of sunlight illuminating the rear passenger's eye area in real time and transmits it to the zero-gravity seat controller. The zero-gravity seat controller processes the visual signal using an image recognition algorithm to obtain the real-time position of the rear passenger's eye area and the sunlight exposure. Based on the eye area position and sunlight exposure, it automatically adjusts the posture of the zero-gravity seat to deviate the passenger's eye area from the path of sunlight. This invention addresses the problem of glare encountered by rear passengers by intelligently and automatically improving the convenience of glare-avoidance adjustment and mitigating safety hazards, thereby providing passengers with a better driving experience.

Furthermore, "at least one" refers to one or more, and "more than one" refers to two or more.
