Detailed ways

Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the respective drawings, the same reference numerals indicate the same or corresponding technical features.

1 is a schematic structural view of an interior rear view mirror in an automotive light recognizing system according to an embodiment of the present invention. FIG. 2 is a schematic top plan view of the inner rear view mirror of FIG. 1. FIG.

As can be seen from the figure, the entire interior rear view mirror assembly includes a mount 1, an inner mirror rear case 2, a mirror 3 of the inner rear view mirror, a connector 4, and the like. The mount 1 can attach the inside mirror assembly to the front windshield (not shown) of the vehicle. During daily driving of the vehicle, the driver observes the rear vehicle and road conditions from the mirror 3.

In the illustrated embodiment, the inner rearview mirror includes five light sensors, a left front light sensor 5 disposed at the left front portion of the inner rear view mirror, and a right front light portion disposed at the right front portion of the inner rear view mirror. The sensor 6, the left rear light sensor 7 disposed at the left rear of the inner mirror, the right rear light sensor 8 disposed at the right rear of the inner mirror, and the middle rear portion of the inner rear mirror Light sensor 9. These sensors can be coupled to the outside through communication lines and connectors 4.

In an alternative embodiment, the inner rearview mirrors may have different light sensor arrangements.

For example, in an alternative embodiment, not only two sensors as shown in the figure, namely the left front light sensor 5 and the right front light sensor 6, but also other light sensors may be disposed on the front portion of the inner rear view mirror. . For example, a mid-front light sensor can also be provided on the mid-front of the interior mirror; or a larger number of light sensors can be placed on the front of the interior mirror. All of these sensors on the front of the interior mirrors may be referred to herein as front ray sensors for sensing light in front of or in front of the vehicle. It can be understood that in another optional embodiment, the front portion of the inner rear view mirror may also include only one front light sensor, such as but not limited to being disposed at an intermediate position of the front portion of the inner rear view mirror. .

Similarly, in an alternative embodiment, the side rear portion of the inner rearview mirror may be provided with not only two sensors as shown in the figure, namely the left rear light sensor 7 and the right rear light sensor 8, but also Other side rear light sensors can be provided. Also, it will be appreciated that in another alternative embodiment, the side rear of the interior mirror may also include only one light sensor, such as one of the left rear light sensor 7 or the right rear light sensor 8.

Further, the present invention does not exclude that other light sensors that may be disposed at other locations of the inner mirrors may be provided in alternative embodiments to facilitate further differentiation from the light recognition applications referred to in this application. . On the other hand, in order to enhance the effect of the light sensing, each of the light sensors in the embodiments of the present application may also be a sensor group that is composed of a plurality of individual sensors.

In the illustrated embodiment, front light sensors (eg, left front light sensor 5 and right front light sensor 6) may be disposed on the rear housing 2 of the rear view mirror, and the rear rear light sensor (eg, left rear light sensor 7 and right rear) The light sensor 8) and the mid-back light sensor 9 can be arranged at the mirror 3 of the inner rear view mirror. In order to avoid unintentional appearance, or to avoid undesired detection for reasons such as safety, in an alternative embodiment, these light sensors may be hiddenly disposed inside the rear case 2 or behind the mirror 3.

In order to provide safe assisted control of the vehicle based on these light sensors, the automotive light recognition system may also include a controller (not shown). In an alternative embodiment, the controller may be independently arranged in the interior mirrors, or integrated into the driving computer, or at other suitable locations in the vehicle, depending on the particular design needs. In different cases, the connector 4 in the figure is adapted to connect the light sensor to the controller; or when the controller is located in the inner rear view mirror, it is adapted to connect the controller to the exterior of the rear view mirror assembly, thereby The command signal is output to the outside.

According to an aspect of the invention, the controller can be communicatively coupled to the front light sensor, the side rear light sensor, and the rear light sensor, and the auxiliary safety control of the vehicle based on the light intensity measured by the sensors. For example, the auxiliary safety control of the automobile may include headlight adjustment control, interior rearview mirror automatic anti-glare adjustment control, and/or in-vehicle monitoring recognition control, and the like. Such an arrangement is conducive to improving the intelligence of the vehicle's auxiliary safety control. Based on the teachings of the present application, those skilled in the art will be able to devise more auxiliary safety control items; although not exhaustive herein, it should still fall within the scope of the present application.

For example, in an optional implementation manner, the controller may be based on one or more of the left front light sensor 5, the right front light sensor 6, the left rear light sensor 7, the right rear light sensor 8, and the middle rear light sensor 9. The measured light intensity is one or more of a headlight adjustment control, an interior rearview mirror automatic anti-glare adjustment control, and/or an in-vehicle monitoring recognition control. In this case, the car needs to have a corresponding headlight adjustment device, an interior mirror automatic anti-glare device, and/or an in-vehicle monitoring device (such as a video recording device) controlled by the controller.

It can be seen that the automobile light recognition system as described above is a 360-degree light recognition system, which can solve the limitation of single judgment of the light inside and outside the vehicle in the conventional automobile product, and the inner rearview mirror of the vehicle is used to satisfy the user's observation of the rear view. At the same time, these light sensors recognize the natural light inside and outside the car in front, rear and side.

Since the light recognition direction of each of the foregoing light sensors provides exclusive direction light (including front, rear and side, etc.) recognition ability, the control algorithm is used to determine the combination of ambient light recognition, and then the safety value-assisted headlights (or front The lamp/headlights are intelligently adjusted, and the interior rearview mirrors are automatically anti-glare control. It can maximize the brightness range of the headlights and increase the road safety when the vehicle is in use. When overtaking, changing lanes and reversing, Continuously adjust the anti-glare intervention depth, provide the best rear view clarity, and control the reasonable driver's light intensity vision to ensure a variety of safety functions for parking and driving; also can be used to trigger the day and night image recognition trigger function of the vehicle interior monitoring .

It will be appreciated from the description of the context that aspects of the invention do not necessarily require that each safety assist control be based on the light intensity signal of all of the light sensors. In alternative embodiments, each control action can also be implemented based on one or several of these light sensors.

For example, in one embodiment, the auxiliary safety control can include headlight adjustment control. In this case, the controller can judge whether or not it is at night based on the light intensity measured by the left front light sensor 5, the right front light sensor 6, and the middle rear light sensor 9. When it is judged that it is at night, if the left front light sensor and the right front light sensor respectively sense strong light, the difference between the strong light sensed by the left front light sensor and the right front light sensor is compared twice in a predetermined time, The light angle is judged based on the difference and the lighting unit in the corresponding angular direction in the headlight is turned off.

It can be understood that the above scene is based on the light intensity of the front windshield glass measured by the left front light sensor 5 and the right front light sensor 6, and the light intensity in the direction of the rear windshield glass is measured based on the middle and rear light sensors, and the light intensity in both the front and the rear is When it is recognized as nighttime brightness, it is judged that the vehicle is traveling at night. In this case, if the left front light sensor 5 and the right front light sensor 6 suddenly sense strong light, respectively, it can be considered that a moving light source such as an accompanying car suddenly appears in front of the vehicle. The controller turns off the headlights based on the difference between the difference between the left front light sensor 5 and the right front light sensor 6 and the angle of the light in the memory by comparing the difference between the strong light sensed by the left front light sensor 5 and the right front light sensor 6 respectively within a predetermined time. The lighting unit in the corresponding angular direction closes the headlight illumination towards the facing car, thereby providing a safe view of the light for the meeting vehicle. The aforementioned mapping table may be obtained based on the calculated difference between the sensed strong light and the relative speed, relative distance, relative angle, and the like of the participating vehicles.

Figure 3 is a schematic illustration of a headlight with a portion of the lighting unit turned off as described above. As can be seen from the figure, in the illustrated example, the LED headlights 10 have a number of lighting units 11 arranged in a matrix. During normal driving of the vehicle, these lighting units constitute a group of LED headlights that collectively illuminate a certain range of angles in front. When the vehicle light recognition system determines that there is a meeting vehicle, the illumination unit that illuminates the vehicle to the meeting is turned off as shown in the figure, and the lighting unit of the corresponding illumination angle is sequentially turned off and on as the approaching vehicle approaches, without affecting the own vehicle. The field of view provides a safe view of the light for the participating vehicles.

In a further embodiment, the difference between the strong light sensed by the left front light sensor 5 and the right front light sensor 6 may be continuously compared with the predetermined time as a time interval, and the light angle change is judged according to the difference change and continuously closed. The lighting unit in the corresponding angular direction of the lamp simultaneously turns on the lighting unit in the headlight adjacent to the closed lighting unit. It can be understood that this can continuously provide a safe view of the light for the participating vehicles, ensuring smooth travel and avoiding accidents.

It can be understood that, in the foregoing embodiment, light conditions such as night (or dusk) are determined according to the light intensity of the left front, the right front, and the middle rear sensed by the light sensors, thereby establishing a basis for the night vision safe driving assistance judgment. In the prior art, in order to realize the driving assistance adjustment of the big light line control, it is often necessary to arrange a plurality of expensive camera components when determining the light conditions, which is expensive. The arrangement of this aspect of the invention not only effectively determines the opening of the active auxiliary safety function during the nighttime period, but also greatly reduces the use of the camera elements, thereby effectively saving manufacturing and assembly costs.

This judgment of lighting conditions such as nighttime or dusk is also applicable to other vehicle-assisted safety controls.

For example, in another embodiment, the auxiliary safety control may include an interior mirror automatic anti-glare adjustment control. In this example, the controller can perform automatic rear eye mirror automatic anti-glare adjustment based on the light intensity measured by the front left ray sensor 5, the right front ray sensor 6, and the mid-back ray sensor 9. Specifically, after determining the light conditions such as nighttime and dusk based on the light intensity of the sensors, the inner rear mirror is triggered according to the strong light in the middle and rear (ie, the direction of the rear windshield) sensed by the middle and rear light sensors 9. Anti-glare function.

In order to avoid the driver's incompatibility when the rear view mirror anti-glare is suddenly opened, the inner mirror can be set to continuously change color in the automatic anti-glare adjustment of the inner mirror.

In an optional embodiment, in the automatic anti-glare adjustment of the inner rearview mirror, the inner rearview mirror controls the color change depth of the inner mirror of the inner rearview mirror according to the light intensity measured by the middle and rear light sensor.

The aforementioned continuous color change and color depth can be realized by obtaining pulse values of different frequencies according to the algorithm controller, and the pulse value of the changed frequency is used as the driving signal for driving the inner mirror, and the color of the color changing mirror can be changed along the input value range with the color changing driver. Each grayscale object has a luminance value from 0% (white) to 100% (black). In an alternative embodiment, the gradient of the range of values, such as 16-order gray scale or 64-step gray scale, can also be simplified, thereby reducing the cost of engineering implementation.

Some example scenarios are further described below in conjunction with specific embodiments.

First, the setting is made here, the left front light sensor obtains the left front light brightness, the right front light sensor obtains the right front light brightness, the left rear light sensor obtains the left rear light brightness, the right rear light sensor obtains the right rear light brightness, and the rear rear light sensor. Obtaining the brightness of the middle and rear light; at the same time, setting the first brightness and the second brightness between the daytime natural light brightness and the nighttime natural light brightness, the first brightness is lower than the second brightness, and the setting is greater than Min (the low beam brightness, far The third brightness of the light level). Here, the lower than the first brightness can be understood as the natural light brightness that completely enters the night; the higher than the first brightness and lower than the second brightness can be understood as the natural light brightness of the dusk, the shade or the tunnel with partial light; the third brightness refers to An intermediate value of the brightness of the near and high beam of the vehicle surrounding the environment. Considering the natural light brightness during the day, the natural light intensity at night, the natural light brightness such as dusk and shade, and the brightness of the near and far lights of different vehicles are not certain absolute brightness values, so the first brightness, the second brightness and the third brightness can also be It is limited to take a value within a certain range; in different embodiments, different brightness values may be taken for the first brightness, the second brightness, and the third brightness, respectively.

At this time, in an optional implementation manner, the Max (left front light brightness, right front light brightness) is greater than the first brightness, less than the second brightness, less than the middle and rear light brightness, and the middle and rear light brightness is greater than the third brightness. When the color change mirror is discolored, it is continuously adjusted between the shallow first depth to the fourth depth, and is enhanced as the difference between the middle and rear light brightness and the Max (left front light brightness, right front light brightness) becomes larger; Max (left front light brightness, right front light brightness) is smaller than the first brightness, Max (left rear light brightness, right rear light brightness) is less than the middle and rear light brightness and the middle and rear light brightness is greater than the third brightness, the color change mirror is discolored The deeper fifth depth to the ninth depth is continuously adjusted, and is enhanced as the difference between the mid-back light illuminance and Max (the left rear ray brightness, the right rear ray brightness) becomes larger.

It can be seen from the embodiment that the left front light sensor and the right front light sensor are measured at dusk, shade, etc. according to the brightness of the front windshield, and the color change lens is continuously adjusted in a shallow range when the vehicle is behind the vehicle; the left front light When the sensor and the right front light sensor are measured at night, the brightness of the left and right sides of the vehicle is less than the rear brightness, and the vehicle is behind the vehicle, the discoloration of the color changing mirror is continuously adjusted in a deeper range. The continuous adjustment of the discoloration of the color-changing mirror is performed according to the difference between the illumination brightness of the rear vehicle headlights and the ring mirror light, and the greater the difference between the two, the deeper the discoloration.

In an optional implementation manner, when reversing, if Max (left front light brightness, right front light brightness) is greater than the first brightness, less than the second brightness, less than the middle and rear light brightness, and the middle and rear light brightness is greater than the third Brightness maintains anti-glare discoloration and the discoloration of the color-changing mirror is continuously adjusted between the shallower first depth to the third depth, and the difference between the brightness of the middle and rear light and the Max (left front light brightness, right front light brightness) Become bigger and stronger.

As can be seen from this embodiment, at the time of reversing at dusk, if there is a vehicle at the rear, the anti-glare is maintained and the discoloration of the color-changing mirror is continuously adjusted in a shallow range.

In an optional implementation manner, when reversing, if Max (left front light brightness, right front light brightness) is smaller than the first brightness, Max (left rear light brightness, right rear light brightness) is smaller than the middle rear light brightness and The brightness of the middle and rear light is greater than the third brightness, and the color change of the color changing mirror is continuously adjusted between the deeper fourth depth to the fifth depth, and the brightness of the middle and rear light and Max (the light of the left rear light, the right rear light brightness) The difference becomes larger and stronger.

It can be seen from this embodiment that, when reversing in the middle of the night, if there is a vehicle at the rear, the anti-glare is maintained and the discoloration of the color-changing mirror is continuously adjusted in a deeper range to facilitate the safety.

In different embodiments, the degree of discoloration of the first depth to the ninth depth may be set as needed. It is conceivable that in other embodiments, other numbers of depth variations can also be set, and the aforementioned adjustment interval can also be changed.

As described above, the mid- and rear-light sensors based on the mid-back of the inner mirror (for example, behind the mirror or the color-changing mirror) can track the depth of discoloration required for anti-glare, helping the driver to avoid reflections. At the same time of glare, the excessive color change of the glare mirror is prevented from losing the sharpness required for the illuminating image, and the sharpness of the back-field reflected image is maximized, and the complete road condition information can be provided for overtaking, lane change, and the like. In the parking and reversing, the anti-glare function is retained, and the quality of the image reflected by the inside mirror is further ensured, and the inside mirror view information of the anti-glare and parking requirements is completely preserved, and the visual and balance are balanced. The common need for clarity.

In an optional implementation manner, the auxiliary safety control may further include an in-vehicle monitoring and recognizing control, and the inner rearview mirror is provided with a camcorder (not shown) facing the inside of the vehicle, and the left front light sensor 5 and the right front light. When the light intensity measured by the sensor 6 and the rear light sensor 9 does not reach the daytime light intensity, the controller can trigger the night shooting mode of the recording device to ensure the sharpness of the shooting. Alternatively or alternatively, the inner rearview mirror may be provided with a recording device facing the driver's face, and the controller triggers the recording device according to the light intensity measured by the left rear light sensor 7 and/or the right rear light sensor 8. Night shooting mode. According to this aspect of the invention, the left rear and right rear light can separately determine the ambient light intensity in the vehicle; the left rear light and the right rear light are used to determine the ambient light intensity condition of the vehicle, and provide a trigger for night vision shooting in the vehicle. Condition, when the ambient light does not satisfy the daytime image illuminance, it can advantageously help the night vision image capturing mode in the car to switch to the night shooting mode, thereby improving the image quality of the in-vehicle image. In particular, in the high-quality environment of face recognition, the different light intensity judgments of the bilateral directions of the left rear and the right rear integrated light provide a more accurate interior ambient light reference for image capturing of night vision face recognition. It provides effective switching conditions for face recognition and driver fatigue night vision recognition, maximizes control image shooting night vision application adjustment, ensures high quality shooting of face recognition images, and improves face recognition image recognition rate.

In an optional implementation manner, the right rear light can be preferentially used to determine the ambient light intensity required for the ambient light to trigger nighttime image capture; the left rear light can assist the determination to ensure the necessary image quality required for face recognition. The switching of the day/night image capture can be realized by switching the filter (for example, the infrared filter) in front of the recording device by the motor drive, and details are not described herein again.

In connection with the above description, those skilled in the art will be able to teach, and an aspect of the present invention also provides an automobile employing the automotive light recognition system as described above. Accordingly, such a car would have the corresponding advantages of the aforementioned automotive light recognition system.
