Detailed Description
The vehicle and the vehicle light control method and device provided by the embodiment of the application are used for reducing the influence of a driver on glare under the condition that the driver can observe the surrounding environment well.
The preferred embodiments of the present application will be described below with reference to the accompanying drawings of the specification, it should be understood that the preferred embodiments described herein are merely for illustrating and explaining the present application, and are not intended to limit the present application, and that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
To facilitate understanding of the present application, the present application refers to technical terms in which:
1. the antireflection film is made of a material having a refractive index between that of glass and air. When light enters the reflection increasing film, a part of the light is reflected back on two surfaces of the reflection increasing film, and the reflected light (namely two lines of light waves) interferes. When the thickness of the reflection increasing film meets a certain condition, two lines of reflected light waves are coherently superposed, according to the law of conservation of energy, most of energy is reflected, and a small part of energy passes through the lens, so that the effects of increasing reflection and reducing transmission are achieved. The best condition for increased reflection is that the thickness of the film is an index of refraction that is an even multiple of the wavelength of the incident light 1/4. That is, the reflection increasing film with a specific thickness can only achieve the best effect for the light with a specific wavelength, the reflection increasing effect for the light with other wavelengths is reduced, and the light with different wavelengths emits different colors. Therefore, based on the principle, the application achieves the effect that the driver is affected by the dazzling light through configuring the reflection increasing film matched with the color of the vehicle body.
2. The colors can be divided into two categories of achromatic colors and chromatic colors, wherein the achromatic colors refer to black, white, gray and the like; the chromatic colors refer to the seven colors of red, yellow, blue, etc.
Referring to fig. 1a, the embodiment of the present application provides a vehicle, comprising a vehicle body 101 and a lamp control system 102 (the lamp control system belongs to a large system, needs wiring to be implemented, but the wiring is invisible, so the specific position of the lamp control system is not shown in fig. 1a), an exterior mirror 103 and a rear windshield are installed on the vehicle body 101, the exterior mirror 103 comprises a left exterior mirror and a right exterior mirror, and the exterior mirror 103 is provided with a mirror having reflection and transmission functions, and the above-mentioned mirror 104 having reflection and transmission functions is provided in the direction of an incident light beam to the exterior mirror 103, a plan view of the exterior mirror 103 and the mirror 104 having reflection and transmission functions is shown with reference to fig. 1b, the lens with the reflection and transmission functions is used for reflecting the light beams matched with the color of the vehicle body and transmitting the light beams of other colors; and/or, the rear windshield 105 is a rear windshield having reflection and transmission functions, and the rear windshield 105 having reflection and transmission functions is used for reflecting light beams matched with the color of the vehicle body and transmitting light beams of other colors.
Alternatively, the mirror 104 with reflection and transmission functions in the present application can be, but is not limited to, a transparent mirror coated with a reflection increasing film in the direction of the incident light beam; and the rear windshield 105 having reflection and transmission functions in the present application may be, but not limited to, a transparent glass coated with an antireflection film to the outside. The present invention is not limited to the material of the lens, and the lens may be a plastic lens, a glass lens, or the like.
The vehicle lamp control system includes a lamp controller 1021, a head lamp 1022 connected to the lamp controller 1021, and a light sensor 1023 for detecting light ahead of the vehicle, as shown in fig. 2. In practice, the headlamps 1022 and optical sensors are disposed on the vehicle body 101, and the lamp controller 1021 would typically be packaged out of view of the vehicle occupants.
Specifically, the headlamp 1022 and the light sensor 1023 may be electrically connected to the lamp controller 1021 through an electrical connection, which may be a wired connection or a wireless connection, where the wired connection refers to a connection of the lamp controller 1021 with the headlamp 1022 and the light sensor 1023 through a wiring, and the wireless connection may be a bluetooth connection or the like.
A lamp controller 1021 in the embodiment of the present application, configured to receive light data reflected by a vehicle ahead detected by a light sensor 1023; determining the body color of the front vehicle according to the light data; the headlamps 1022 are controlled to emit light of a color matching the body color of the vehicle in front according to the body color of the vehicle in front, so that the light emitted by the headlamps 1022 is reflected by the mirror 104 having the reflecting and transmitting functions and/or the rear windshield 105 having the reflecting and transmitting functions provided on the outside mirror 103 of the vehicle in front.
In the following description, taking two vehicles shown in fig. 3 and provided based on the present application as an example, assuming that a right-side vehicle in fig. 3 is a current vehicle and a left-side vehicle is a vehicle ahead of the current vehicle, during driving at night, in order to ensure driving safety, a headlamp 1022 of the current vehicle is turned on to perform an illumination function, so that light is inevitably irradiated onto the vehicle ahead, and therefore, a light sensor 1023 in the current vehicle detects light data reflected by the vehicle ahead and sends the detected light data to a vehicle lamp controller 1021; after receiving the light data, the lamp controller 1021 determines the body color of the front vehicle according to the light data, and then controls the headlamps 1022 to emit lights of colors matching the body color of the front vehicle according to the determined body color of the front vehicle.
In a possible embodiment, when the head lamp 1022 of the vehicle at night is irradiated on the body 101 of the vehicle in front, if the vehicle in front adopts the exterior mirror 103 provided in the prior art, it can be seen from fig. 4a that a large amount of light incident on the exterior mirror 103 is reflected to the eyes of the driver, which easily dazzles the driver and affects night driving. In order to solve this problem, the present application proposes that a mirror 104 having reflection and transmission functions can be attached to the outside mirror 103 perpendicularly to the vehicle body 101, even if no reference is made to the rear windshield 105, by providing the mirror 104 having the reflection and transmission functions, when light is incident on the mirror 104 having the reflection and transmission functions, so that a part of the light is reflected by the mirror 104 having the reflection and transmission functions, referring to the optical path diagrams in the top views shown in fig. 4b and 4c, as can be seen from the optical path diagram in fig. 4b, a part of the light beam is reflected, that is, only a part of the light is transmitted to the outside rear-view mirror 103 and reflected to the eyes of the driver of the vehicle ahead, therefore, the occurrence of dazzling caused by the eyes of the driver of the front vehicle with a large amount of light reflected is avoided, and the anti-dazzling function is realized; and a part of light beams in the light path diagram of fig. 4c are transmitted to the exterior mirror 103 and then reflected to the eyes of the driver through the exterior mirror 103, that is, because a part of light is reflected to the eyes of the driver, the driver of the front vehicle can observe the surrounding driving road conditions based on the light reflected to the eyes, and the driving safety is further ensured.
Another possible embodiment is that, if the front vehicle uses the rear windshield 105 provided in the prior art, when the headlamps 1022 of the vehicle located behind during the night drive illuminate the rear windshield 105, the headlamps are directly transmitted to the inside rearview mirrors and then directly reflected to the eyes of the driver through the inside rearview mirrors, that is, a large amount of light enters the eyes of the driver, which is very likely to cause dazzling. In order to solve this problem, it is also possible to design the rear windshield 105 such that when the rear windshield 105 of the present application is provided with the reflective and transmissive functions and light of a color matching the color of the body of the vehicle in front emitted from the headlights 1022 of the vehicle in front is irradiated onto the rear windshield 105 of the vehicle in front, the light path diagrams of the rear windshield 105 and the interior mirror 106 in plan view are shown with reference to fig. 5a and 5b, and it can be seen that even if nothing is done with respect to the headlights 1022, since the rear windshield 105 is provided with the reflective and transmissive functions, a part of the light is reflected back and does not reach the interior mirror 106 (fig. 1a), as shown with reference to fig. 5a, only another part of the light is transmitted onto the interior mirror 106, as shown with reference to fig. 5b, is reflected onto the eyes of the driver via the interior mirror 106, based on this embodiment, because only partly light shines driver's eyes, so effectively reduced the quantity of incidenting the light of driver's eyes to reduced the influence of driver to dazzling light, in addition, the driver has guaranteed the security of driving night because of can seeing the road conditions around clearly based on reflecting the light of eyes.
In another possible embodiment, referring to fig. 4a to 5b, when the light of the color matching the color of the body of the front vehicle emitted by the front lamp 1022 is irradiated onto the exterior mirror 103 provided with the lens 104 having the reflection and transmission functions and onto the rear windshield 105 having the reflection and transmission functions of the front vehicle, since both the exterior mirror 103 and the rear windshield 105 are processed, a part of the light irradiated onto both the exterior mirror 103 and the rear windshield is reflected and transmitted, the amount of light incident on the eyes of the driver of the front vehicle is further reduced, and thus the anti-glare function is realized, and meanwhile, the driver observes the surrounding environment based on the light incident on the eyes, and the safety of driving at night is ensured.
Alternatively, each of the front lamps 1022 in the present application includes a halogen lamp and a Light Emitting Diode (LED) lamp of three primary colors, wherein the three primary colors are red, green, and blue.
On the basis of this, the body color of the preceding vehicle can be determined in the following manner: the vehicle lamp controller 1021 in the present application is specifically configured to control three primary color LED lamps in the headlamp 1022 to sequentially emit single-color light of three colors of red, green, and blue, and light of multiple mixed colors; determining the light intensity of the light reflected by the body 101 of the preceding vehicle in the case where the headlights 1022 emit lights of different colors, based on the light data detected by the light sensor 1023; comparing the light intensities of the light reflected by the body 101 of the preceding vehicle in the case where the headlights 1022 emit lights of different colors; and determining the body color of the front vehicle according to the comparison result.
Specifically, based on the physical laws, when the vehicle body 101 is irradiated with the light having the same color as the vehicle body, the intensity of the light reflected by the vehicle body 101 is strongest, based on the principle, the vehicle lamp controller 1021 of the present application irradiates the vehicle body 101 of the vehicle ahead by controlling the three primary color LED lamps to emit the light having different colors, then the light sensor 1023 detects the light data reflected by the vehicle body 101 based on each color emitted by the head lamp 1022 and transmits the light data to the vehicle lamp controller 1021, and then the vehicle lamp controller 1021 determines the intensity of the light reflected by the vehicle body 101 in the color based on the light data emitted by the head lamp 1022 in each color, so that the vehicle lamp controller 1021 can compare the intensity of the light reflected by the vehicle body 101 of the vehicle ahead in the case where the head lamp 1022 emits the light having different colors, and then determine the vehicle body color of the vehicle ahead according.
In specific implementation, if the light intensity of one primary color is strongest, determining the color corresponding to the strongest light intensity as the body color of the front vehicle, for example, if the light intensity of red is determined to be strongest, determining the body color of the front vehicle to be red; if the light intensities of the two primary colors are strong, determining the combined color of the two primary colors as the body color of the front vehicle, for example, if the light intensities of the red color and the blue color are strongest, determining the combined color of the red color and the blue color, namely purple, as the body color of the front vehicle; if the light intensities of the three primary colors are strong, determining that the color of the front vehicle body is white; if it is determined that the light intensities of the three primary colors are all very weak, it can be determined that the body color of the vehicle in front is black.
In an implementation, the lamp controller 1021 may adjust the driving voltages of the red LED, the green LED and the blue LED in the three primary color LED lamp according to the desired emission color, so that the color of the mixed light beam of the red LED, the green LED and the blue LED is the desired emission color. For example, if the lamp controller 1021 desires the headlight 1022 to emit yellow light, since yellow can be made of red and green, the driving voltages of the red LED and the green LED can be increased, the driving voltage of the blue LED can be decreased, or the driving voltage of the blue LED can be adjusted to 0, and thus, the headlight 1022 can emit yellow light by mixing the red light beam with the green light beam.
Furthermore, it is also possible to adjust the timing of the light emission by the three primary color LED lamps, namely: the amount of time that the red, green and blue LEDs are illuminated is controlled to achieve the desired color emission. For example, if the color of the vehicle body of the vehicle in front is yellow (desired emission color), the light emission time of the red LED and the green LED may be controlled to be longer and the light emission time of the blue LED may be controlled to be shorter, so that the lights of the three colors are mixed to obtain yellow light.
Optionally, the vehicle light controller 1021 is specifically configured to: if the color of the front vehicle body is determined to be achromatic, turning on a halogen lamp; and if the color of the vehicle body of the front vehicle is determined to be colorful, controlling the color of the mixed light beam of the three primary colors LED lamps to be the same as the color of the vehicle body.
Specifically, the achromatic color in the present invention can be, but is not limited to, white, gray, black or a combination of the aforementioned three colors; and the chromatic colors may be, but are not limited to, red, orange, yellow, green, cyan, blue, violet, or a combination of colors.
On the basis, if the color of the vehicle body of the vehicle is an achromatic color, the thickness of the reflection increasing film satisfies the following condition: the product of the thickness of the reflection increasing film and the refractive index of the reflection increasing film is positively correlated with the even number times of one quarter of the wavelength of the light emitted by the halogen lamp; if the color of the vehicle body of the vehicle is colorful, the thickness of the reflection increasing film satisfies the following conditions: the product of the thickness of the reflection increasing film and the refractive index of the reflection increasing film is positively correlated with the even number times of one quarter of the wavelength of the light corresponding to the color of the vehicle body.
In particular, the positive correlation in the present invention is understood to mean that the thickness of the reflection increasing film can be set to an even multiple of λ/4n, where n is the refractive index of the reflection increasing film and λ is the wavelength of light; if the color of the car body is black/gray/white, lambda is the wavelength of light emitted by the halogen lamp, and the halogen lamp generally emits light with a yellow color; when the vehicle body color is red, λ is the wavelength of red light.
Alternatively, the light ray sensor 1023 in the present application may be provided to the camera and/or separately provided, and the light ray sensor 1023 may be, but not limited to, a three primary color optical sensor or the like.
Optionally, the vehicle body 101 of the vehicle in the present application is further provided with an image detection device for detecting an image in front of the vehicle;
the vehicle controller is further configured to: acquiring an image detected by the image detection device; and recognizing the image, and if the vehicle in front of the vehicle is recognized to exist, sending a data detection instruction to the light ray sensor 1023.
Specifically, the camera may be disposed in the image detection device, the vehicle lamp controller 1021 may send an image capturing instruction to the image detection device, and then the image capturing device may drive the camera to capture an image in front of the vehicle after receiving the image capturing instruction, and then send the captured image to the vehicle lamp controller 1021. The vehicle light controller 1021 can recognize the image in front of the vehicle collected by the camera, and if it is recognized that the vehicle exists in front of the vehicle based on the image, that is, when the vehicle exists in front of the image collection range, the vehicle light controller sends a data detection instruction to the light sensor 1023, so that the light sensor 1023 can detect the light data emitted by the vehicle in front after receiving the data detection instruction, and thus, the situation that the light sensor 1023 is damaged due to long-time working state can be avoided.
Next, a vehicle light control method based on the vehicle described above is described, and as shown in fig. 6, the method may include the following steps:
and S61, receiving the light ray data reflected by the front vehicle detected by the light ray sensor.
Specifically, during night driving, the headlamps 1022 of the vehicle are inevitably turned on, so that the headlamps 1022 are irradiated on the vehicle body 101 of the preceding vehicle, and for the purpose of anti-glare, the light sensor 1023 is required to detect light data reflected by the light irradiated by the headlamps 1022 from the preceding vehicle.
And S62, determining the color of the front vehicle body according to the light data.
Alternatively, step S62 may be implemented according to the flow shown in fig. 7, including the following steps:
and S71, controlling the three primary colors LED lamps in the head lamp to sequentially emit single-color light of three colors of red, green and blue and light of a plurality of mixed colors.
And S72, determining the light intensity of the light reflected by the body of the front vehicle under the condition that the headlamps emit light with different colors according to the light data detected by the light sensor.
And S73, comparing the light intensity of the light reflected by the body of the front vehicle under the condition that the headlamps emit light with different colors.
And S74, determining the color of the front vehicle according to the comparison result.
In the process shown in fig. 7, in order to accurately determine the body color of the vehicle ahead, the lamp controller 1021 starts a lamp color scanning mode, and the scanning method includes: the three primary colors of LEDs in the headlamp 1022 are sequentially controlled to emit three monochromatic lights of red, green and blue and mixed colors of red, green, red, blue and green, and the light of each color is always emitted within 10ms, so that the light sensor 1023 detects the light intensity of the light reflected by the vehicle body 101 of the vehicle in front under the light of the color and sends the light intensity to the vehicle lamp controller 1021; thus, the lamp controller 1021 can acquire the light intensities corresponding to the 6 colors, compare the 6 light intensities, and determine the color of the front vehicle body according to the comparison result.
And S63, controlling the front lamp to emit light with the color matched with the color of the front vehicle body according to the color of the front vehicle body, so that the light emitted by the front lamp is reflected by a lens with the reflection and transmission functions and/or a rear windshield with the reflection and transmission functions arranged on the outside rearview mirror of the front vehicle.
In the step, if the color of the front vehicle body is determined to be achromatic, turning on a halogen lamp;
and if the color of the vehicle body of the front vehicle is determined to be colorful, controlling the color of the mixed light beam of the three primary colors LED lamps to be the same as the color of the vehicle body.
Specifically, when it is determined that the body color of the vehicle in front is gray, the head lamps 1022 are controlled to emit yellowish light (the color of light emitted from the halogen lamps), and when the yellowish light is irradiated onto the body 101 of the vehicle in front, since the body color of the vehicle in front is an antireflection film designed based on the wavelength of the yellowish light, when the light is irradiated onto the antireflection film, the yellowish light is reflected back by the antireflection film, and only a small portion of the non-yellowish light is transmitted from the antireflection film onto the exterior mirror 103 and/or the interior mirror, so that the amount of light reflected to the eye position of the driver via the exterior mirror 103 and/or the interior mirror is greatly reduced, that is, the light intensity incident to the eyes of the driver is reduced, thereby achieving the anti-glare purpose, and further, since a small amount of light can be normally incident to the eyes of the driver, thus ensuring the driver to observe the surrounding environment at night.
If it is determined that the color of the vehicle body of the vehicle in front is red, the three primary color LED lamps in the headlamp 1022 are controlled to only drive the red LEDs to emit red light, when the red light irradiates the vehicle body 101 of the vehicle in front, since the color of the vehicle body of the vehicle in front is the reflection enhancement film designed based on the wavelength of the red light, when the light irradiates the reflection enhancement film, the red light is almost completely reflected by the reflection enhancement film, and only a small part of the non-red light is transmitted from the reflection enhancement film to the exterior mirror 103 and/or the interior mirror, so that the anti-glare purpose can be achieved, and meanwhile, the night observation of the driver is not affected.
