Detailed Description
The utility model provides a vehicle light control method. As shown in fig. 1, the vehicle 101 includes a warning light projector 102, and the warning light projector 102 projects a warning light 111 toward the ground, and the warning light 111 is located behind the vehicle 101 (the vehicle 101 travels rightward in fig. 1). Specifically, the warning light 111 is elongated in shape, and is directed parallel to the vehicle tail (perpendicular to the center axis of the vehicle). In the present embodiment, the first direction is defined as the rear of the vehicle. The control method provided by the utility model is shown in fig. 2, and comprises a step a 251: acquiring information of whether an object exists in the first direction or not; comprising a step B252: acquiring the distance L from the object to the vehicle; comprising step 253 of: controlling the lighting state of the warning projector 102 according to the distance L includes: if the distance L is larger than the specific safety distance, the warning projector is in a first normal working state; if the distance L is smaller than the specific safety distance, the warning projection lamp is in a first warning working state, wherein the visual effect of the warning light in the first normal working state is different from that in the first warning working state.
The working principle of the present utility model is specifically described below. Step a 251 is used to find out whether there are other vehicles (or objects) behind the host vehicle (in the first direction), and if there are other vehicles, the distance L from the host vehicle to the host vehicle can be obtained according to step B252. In step 253, if the distance L is greater than the specific safety distance (e.g., 10 meters), the warning light projector is in the first normal working state. In this embodiment, the first normal operating state is normally on. If the judgment distance L is smaller than the specific safety distance, the possible collision risk is considered to be very high, and the warning projector is in the first warning working state. In this embodiment, the first alert operation state is flashing. The flashing warning light 111 can form visual stimulus to the driver of the vehicle approaching behind the vehicle, so that the driver can pay attention to the distance maintenance of the vehicle, and the purpose of reducing the collision risk is achieved. Of course, the first normal working state may be off, and the first warning working state is flashing or normally bright, so that the change of the visual effect of the warning light also prompts the driver of the rear vehicle to have collision risk. As another example, the first normal operating state may also be a low frequency flicker, the first alert operating state is a high frequency flicker, or the first normal operating state is white and the first alert operating state is red. In summary, a change in the visual effect of the warning light may indicate to the driver of the rear vehicle that there is a risk of collision. The change in visual effect may include a change in frequency, a change in color, a change in shade, etc., which are not illustrated herein.
In this embodiment, the step a 251 and the step B252 may be performed simultaneously, that is, the distance L from the object to the host vehicle is measured while the object behind is found. For example, using range radar, both a 251 and B252 steps may be implemented. Of course, the a step 251 and the B step 252 may be implemented separately. For example, step a 251 may be implemented using an inexpensive camera-based recognition algorithm. And B252 may be implemented using a radar or binocular camera. In summary, in the description of the present utility model, step number A, B, C … … is merely a code for convenience of description and does not represent the order of steps, and it can be seen that step E or F precedes step C in the following examples.
In this embodiment, the warning light is in a long bar shape, which is the most effective way, and also a striking output of high brightness is easily achieved. Preferably, the aspect ratio of the elongated alert light is greater than 5:1, i.e., sufficiently elongated, for best visual effect. In practice, the warning light may be of other shapes or projected to form a pattern, which falls within the scope of the present utility model.
In the present embodiment, the first direction refers to the rear of the vehicle. The first direction may actually be the front of the vehicle. As shown in fig. 3, unlike the embodiment shown in fig. 1, the vehicle 301 of the present embodiment includes a warning projector 302, the warning projector 302 projecting a warning light 312 toward the ground, the warning light 312 being located in front of the vehicle 301. According to the working principle of the present utility model shown in fig. 2, when the vehicle or object in front of the vehicle reaches within a specific safety distance, the warning light 312 changes state to alert the driver of the vehicle to the collision risk. Further, the first direction may be a front left direction, a front right direction, a rear left direction, or a rear right direction. As shown in fig. 4, unlike the foregoing embodiment, the vehicle 401 of the present embodiment includes a warning light projector 402, the warning light projector 402 projects a warning light 413 toward the ground, and the warning light 413 is located at the rear left of the vehicle 401, so that the first direction may be the rear left, and the strip-shaped direction of the test warning light projector is parallel to the vehicle center axis direction. According to the working principle of the present utility model shown in fig. 2, when the rear left vehicle is within a certain safety distance from the host vehicle, the warning light 413 changes its state, so as to alert the driver of the rear left vehicle to the risk of collision. Similarly, the vehicle 401 of the present embodiment includes a warning light projector 403, and the warning light projector 403 projects a warning light 414 toward the ground, and the warning light 414 is located at the rear right of the vehicle 401, so that the first direction may be the rear right. According to the working principle of the present utility model shown in fig. 2, when the distance between the right rear vehicle and the host vehicle is within a specific safety distance, the warning light 414 changes its state, so as to alert the driver of the right rear vehicle to the collision risk. Similarly, the vehicle 401 of the present embodiment includes a warning light projector 404, and the warning light projector 404 projects a warning light 415 toward the ground, and the warning light 415 is located in the left front of the vehicle 401, so that the first direction may be the left front. According to the working principle of the present utility model shown in fig. 2, when the distance from the vehicle to the front left vehicle or object is within a specific safety distance, the warning light 415 changes its state, so as to alert the driver of the vehicle to the risk of collision. Similarly, the vehicle 401 of the present embodiment includes a warning light projector 405, and the warning light projector 405 projects a warning light 416 toward the ground, and the warning light 416 is located in the front right of the vehicle 401, so that the first direction may be the front right. According to the working principle of the present utility model shown in fig. 2, when the distance from the vehicle to the front right vehicle or object is within a specific safety distance, the warning light 416 changes state to alert the driver of the vehicle to the collision risk. In summary, the first direction may be any direction, and the elongated directions of the warning lights in different directions may be different.
In another embodiment of the present utility model, as shown in fig. 5, the vehicle light control method further includes a step D562: and acquiring state information of the vehicle. Based on the status information of the host vehicle, the C step 553 further includes: if the vehicle is in a flameout state, if the distance L is greater than a specific safety distance, the warning projection lamp is in a second normal working state; if the distance L is smaller than the specific safety distance, the warning projection lamp is in a second warning working state, wherein the visual effect of the warning light in the second normal working state is different from that of the warning light in the second warning working state. It will be appreciated that the vehicle may be subject to an external collision even in the off state, and thus when an external object (e.g., another vehicle, a pedestrian, an electric vehicle, etc.) approaches the vehicle, the warning light projector is in the second warning operating state to alert the external object to avoid the collision. For example, the second normal working state is the off state, the second warning working state is normally bright or blinks, and the state change of the warning light can remind the external object and the controller thereof of paying attention to the collision risk.
Another difference between this embodiment and the embodiment shown in fig. 2 is that the two steps of obtaining the information about whether the host vehicle has an object in the first direction in the step a and obtaining the distance L from the object to the host vehicle in the step B are combined into one step 551, and for example, the two functions can be simultaneously implemented by using a range radar.
In the above embodiments, specific safe distances are mentioned. The distance is used to determine whether there is a risk of collision with other objects or the distance L of the object to the host vehicle. In practice, this particular safe distance may be related to the real-time speed of the host vehicle. It is known that the faster the vehicle speed, the farther the safety distance is, so in practice, the specific safety distance may not be a specific value, but a safety distance calculated from the vehicle speed in real time.
In another embodiment of the present utility model, as shown in fig. 6, step 653 further includes: and if the distance L is smaller than the specific safety distance, prompting the personnel in the vehicle. The prompting may be visual or audible, and is not limited herein. Therefore, the driver of the vehicle can be more clearly aware of the occurrence of risks, and take the risk avoiding measures in time.
In another embodiment of the present utility model, as shown in fig. 7, the method further includes an E step 763: luminance information of ambient light outside the vehicle is acquired. Step 753 further includes adjusting driving power of the warning projector according to brightness information of the ambient light outside the vehicle. Here, adjusting the driving power of the warning projector is not equivalent to changing the lighting state as described above. For example, when the warning projector is in a normally-on state (first normal working state) and the external ambient light is relatively dark, the driving power of the warning projector can be adjusted to reduce the brightness so as to avoid glaring due to overhigh brightness. It can be understood that adjusting the driving power of the warning projector does not change the lighting states such as normal lighting, flickering, etc.
In another embodiment of the present utility model, as shown in fig. 8, the method further includes step 863: and acquiring weather information outside the vehicle. Step 853 further includes turning off the warning projector if the vehicle exterior is in snowy and rainy weather. If the outside of the vehicle is in rainy and snowy weather, the ground can reflect light due to the rainy and snowy weather. At this time, for safety reasons, the warning light projector is turned off, so that glare of eyes of drivers of other vehicles due to reflection of light on the ground can be avoided.
The utility model also provides a vehicle light control system, wherein the vehicle comprises a warning light projector, the warning light projector projects warning light to the ground, and the warning light is positioned in a first direction of the vehicle. The vehicle light control system of the present utility model includes: the detection device is used for acquiring information of whether the vehicle has an object in a first direction or not and acquiring the distance L between the object and the vehicle; the control device is used for controlling the lighting state of the warning projection lamp according to the distance L, and comprises: if the distance L is larger than the specific safety distance, the warning projector is in a first normal working state; if the distance L is smaller than the specific safety distance, the warning projection lamp is in a first warning working state, wherein the visual effect of the warning light in the first normal working state is different from that in the first warning working state.
As previously mentioned, in particular, it is preferred that the detection means comprise a camera or radar. In order to make the warning light more striking, it is preferable that the warning light is in a long strip shape. More preferably, the warning light is a striking yellow or green color. Of course, white warning lights are also possible in view of the appearance effect. In fact, the shape and color of the warning light are not limited by the present utility model.
Preferably, the warning projector uses laser as a light source, and has the advantages of high brightness and easy attention of human eyes. Considering that pure laser has the injury risk of human eyes, therefore, the warning projecting lamp can also use laser as an excitation source for exciting fluorescent materials to form wide-spectrum white light or the laser of chromatic light, so that the high-brightness output is realized, and the safety of lamplight is also ensured.
As can be seen from the above description, the present utility model also provides a vehicle, which includes a warning light projector mounted on an outer surface of the vehicle, and the warning light projector projects a long-strip-shaped warning light (as shown in fig. 1) toward the ground behind the vehicle, and the long-strip-shaped warning light direction of the warning light is perpendicular to the direction of the central axis of the vehicle. The aspect ratio of the warning light is greater than 5:1. Preferably, the vehicle further comprises a detection device, which is used for acquiring information of whether the vehicle has an object at the rear or not, and also used for acquiring the distance L from the object to the vehicle; still include controlling means for according to the illumination state of distance L control warning projecting lamp, include: if the distance L is larger than the specific safety distance, the warning projector is in a first normal working state; if the distance L is smaller than the specific safety distance, the warning projection lamp is in a first warning working state, wherein the visual effect of the warning light in the first normal working state is different from that in the first warning working state. For example, the first normal operation state is normally bright, and the first warning operation state is blinking.
The warning light may be white or yellow or green or yellowish green, which is not limited in the present utility model.
As shown in fig. 1, the vehicle includes two warning lights 102, which may be formed separately. In the embodiment shown in fig. 1, the two warning lights coincide, which results in a relatively high brightness. In practice, this is just one case distance. Preferably, the two warning lights are located on the same straight line. For example, in fig. 1, two warning lights formed by two warning light projectors are only on the same straight line, and can be visually seen as a whole, so that each warning light can be shorter, and the design difficulty is reduced. Preferably, the two warning lights are at least partially overlapped to form a whole, so that fusion can be formed visually. Of course, the extreme case is that the two warning lights are completely coincident, as shown in fig. 1.
In order to improve the brightness of the warning light, preferably, the warning projector comprises a laser generator and a fluorescent material, wherein the laser generator emits laser as an excitation source, and the laser excites the fluorescent material to generate laser light. The laser has the characteristic of high brightness, and the laser-receiving light generated by exciting the fluorescent material by the high-brightness laser also has the characteristic of high brightness. Preferably, the strip-shaped trend of the warning light is parallel to the fast axis direction of the laser. As shown in fig. 9, the laser generator 901 emits laser light to form a laser spot 931, and the laser generator emits light not isotropically but with a fast axis direction and a slow axis direction orthogonal to each other, the fast axis direction being a direction B and the slow axis direction being a direction a in fig. 9, and the divergence angle of the laser light emitted from the laser generator in the fast axis direction is larger than the divergence angle thereof in the slow axis direction. The direction of the long strip of the warning light is parallel to the fast axis direction of the laser, so that the characteristic that the divergence angles of the fast axis direction and the slow axis direction of the laser light are different can be utilized, uniform long strip light spots can be formed more easily, the optical design is simpler, and the cost is lower. More preferably, the warning projector further comprises a filter at the rear end of the fluorescent material light path, and the filter is used for guiding the laser to emit and at least partially filtering out the laser. For example, the filter may transmit lasing light (e.g., yellow or green light) while reflecting excitation light (e.g., blue light) such that the lasing light may be directed out through transmission while the excitation light is not. For another example, the filter may reflect the laser light while transmitting the laser light, and the optical path of the rear end may receive the laser light from the reflected optical path, such that the transmitted laser light is not received by the rear end optical path and is filtered. In a word, the filter is used for reducing or even eliminating laser components in the emergent light, so that the biosafety of the emergent light can be improved, and the possibility and proportion of the emergent laser are reduced.
Preferably, the vehicle further comprises a second warning light projecting in a strip form to the ground in front of the vehicle, the strip form of the warning light running perpendicular to the direction of the central axis of the vehicle, as shown in fig. 3. Alternatively, the second warning projector projects a long-strip warning light to the ground in front of the vehicle side or behind the vehicle side or to the side, and the long-strip direction of the warning light is parallel to the direction of the vehicle center axis, for example, as shown in fig. 4. The periphery of the vehicle is surrounded by the warning light, so that the vehicle can be protected in a best light mode.
It should be noted that the term "lamp" as used herein refers to a lamp in a broad sense, and the term "lamp" refers to a lamp for vehicles traveling on a road, and does not necessarily refer to an automobile lamp, but includes an electric lamp, a bicycle lamp, and the like.
It should be noted that the distinguishing technical features between the embodiments of the present utility model are not limited to the application to the respective embodiments, but may be applied to the respective embodiments, and it is impossible to enumerate all possible combinations in the description of the present utility model, so that the implementation principles and advantages of the respective technical features are described by way of example, and those skilled in the art will realize the advantages by using the implementation principles when applied to other embodiments.
The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
