The embodiment of the application provides a car lamp lighting method, which is used for controlling a car lamp to automatically switch the lighting mode of the car lamp according to traffic conditions. The vehicle lamp in the embodiment of the present application may refer to various types of vehicle lamps such as a head lamp, a tail lamp, a turn lamp, and a license plate lamp. The car light in this application embodiment has multiple illumination mode, and the light effect of different illumination mode car lights is different, like head-light has high beam illumination mode and low beam illumination mode.
The related art has a technical means of automatically switching the illumination mode of the vehicle lamp so as to adapt the vehicle lamp to various traffic conditions, but the switching accuracy is relatively poor. The following is an analysis of the reason why the switching of the illumination mode of the lamp is not accurate enough in the related art, and it should be noted that the analysis process and the analysis conclusion are part of the inventive aspects of the present application.
In the related art, the type of the road is judged through single information, and then the lamp is controlled to switch the illumination mode based on the type of the road. For example, the illumination mode of the lamp is switched according to the vehicle speed, the high beam illumination mode is selected when the vehicle speed is high, and the low beam illumination mode is adopted when the vehicle speed is low. Judging the type of the road through single information is not reliable enough, for example, the failure of an acquisition device for acquiring the information can lead to failure of information acquisition or the occurrence of error information acquisition, and further the type of the road cannot be effectively judged. Moreover, even if the information is accurately acquired, the single information often cannot accurately reflect the type of the road.
In view of this, an embodiment of the present application provides a vehicle lamp illumination mode, referring to fig. 1, the vehicle lamp illumination method includes:
s101, starting the vehicle.
S102, acquiring vehicle motion information.
S103, visual information of a road in front of the vehicle is acquired.
S104, judging the type of the road;
it should be noted that this means that the type of road is judged based on the vehicle motion information and the visual information.
S105, generating a target control instruction;
it should be explained that this means that the target control instruction is generated based on the type of the road.
S106, switching the illumination mode of the car lamp;
it should be noted that this means that the lighting mode of the lamp is switched according to the target control command, so that the lighting effect is changed.
According to the car lamp lighting method, the type of the road is judged through the vehicle motion information and the visual information, so that the type judgment of the road has higher accuracy. The target control instruction for controlling the lamp lighting mode is generated based on the judgment of the type of the road, the judgment accuracy of the type of the road is high, and the switching accuracy of the lamp lighting mode can be high. Therefore, the vehicle lamp illumination method provided by the embodiment of the application can improve the accuracy of switching the vehicle lamp illumination modes.
It should be noted that, in the embodiment of the present application, the vehicle motion information may be vehicle speed information, whether the vehicle is turning, a steering angle of the vehicle, and the like. In some embodiments of the present application, the vehicle speed information may be obtained by a vehicle speed sensor.
It should be noted that, the roads in the embodiments of the present application refer to roads in front of the vehicle, that is, in front of the traveling direction of the vehicle. In some embodiments of the present application, a road may refer to a road within 100 meters, 150 meters, or 200 meters in front of a vehicle.
It should be noted that the types of roads may include urban roads, town roads, expressways, plant roads, forest roads, country roads, rail transit lines, field roads, public parking lots, curves of different curvatures, curves of different kinds, and the like.
The visual information acquisition module can be adjusted according to the actual service scene of the vehicle, so that the visual information acquisition module only acquires information aiming at the characteristic information of a specific road. For example, the vehicle is a car, and the visual information acquisition module can only acquire the characteristics of urban roads, town roads, expressways and curves. If the vehicle is an off-road vehicle, the visual information acquisition module also needs to acquire the characteristics of an off-road. In some embodiments of the present application, the visual information acquisition module is a camera. The camera may be a forward facing camera or the like.
It should be explained that, in the embodiment of the present application, the determination of the type of the road according to the vehicle movement information and the visual information of the road refers to the determination of the type of the road only by the vehicle movement information and the visual information of the road, and the type of the road can be determined only by the two information.
Illustratively, in some embodiments of the present application, the vehicle lamp is a headlight, and determining the type of road based on the vehicle motion information and the visual information of the road includes any one or more of:
when the visual information of the road represents that the road type is an urban road and the vehicle speed information represents that the vehicle speed is smaller than or equal to a first threshold value, judging that the road type is the urban road. In some embodiments of the present application, the first threshold may be 80km/h. In some embodiments of the present application, the visual information characterizing the type of road as an urban road may include: visual information representation road has street lamp illumination, and the representation road is people car reposition of redundant personnel road.
And when the visual information of the road represents that the road type is the expressway and the vehicle speed information represents that the vehicle speed is greater than or equal to a second threshold value, judging that the road type is the expressway. In some embodiments of the present application, the second threshold may be 80km/h. In some embodiments of the present application, the visual information characterizing the type of road as an expressway may include: the visual information represents that the two sides of the road are provided with isolation bars.
When the visual information of the road represents the road type as the town road and the vehicle speed information represents the vehicle speed less than or equal to a third threshold value, judging the road type as the town road. In some embodiments of the present application, the third threshold may be 60km/h. In some embodiments of the present application, the visual information characterizing the type of road as town road may include: the visual information characterizes the road as a bi-directional lane.
And when the visual information of the road represents that the road type is a curve and the vehicle speed information represents that the vehicle speed is smaller than or equal to a fourth threshold value, judging that the road type is the curve. In some embodiments of the present application, the fourth threshold may be 40km/h. In some embodiments of the present application, the visual information characterizing the type of road as a curve may include: the visual information characterizes the road as having a curvature.
The road type is urban road, and the head lamp can be switched to a conventional illumination mode. The road type is expressway, and the headlight can be switched to a high beam illumination mode. The road type is town road, and the head lamp can be switched to the low beam illumination mode. The road type is a curve, and the head lamp can be switched to a steering illumination mode. The illumination range is a high beam illumination mode, a normal mode, and a low beam illumination mode in this order from a large to a small along the longitudinal direction of the vehicle body. The steering mode is used to direct light to one side of the vehicle to illuminate the steering side of the vehicle.
The following describes, with reference to specific embodiments, judging the type of a road based on vehicle motion information and visual information of the road. Referring to fig. 2, fig. 2 is a flow chart for determining the type of a road, which mainly includes the following steps:
s201, starting the vehicle.
S202, motion information of a vehicle is acquired.
S203, visual information of a road in front of the vehicle is acquired.
S204, generating first state data;
it should be explained that this refers to generating the first state data based on the movement information of the vehicle. For example, when the vehicle speed represented by the vehicle speed information is greater than 40km/h, one type of first state data is generated, and when the vehicle speed represented by the vehicle speed information is less than 40km/h, the other type of first state data is generated. For example, when the vehicle speed is greater than 40km/h, a high-level digital signal is generated, and when the vehicle speed is less than or equal to 40km/h, a high-level digital signal is generated.
Similarly, in some embodiments of the present application, when the vehicle motion information includes a steering angle of the vehicle, different first state data may be generated according to a difference in an angle range in which the steering angle of the vehicle is located. In the case where the vehicle motion information includes steering angle information, vehicle speed information, and the like, different first state data and the like may also be generated according to a difference in combination of an angle range in which the steering angle is located and a vehicle speed range in which the vehicle speed is located.
S205, second state data is generated.
It is to be explained that this means that the second state data is generated based on the visual information of the road in front of the vehicle. For example, the road type represented by the visual information of the road is an urban road, and second state data is generated; the road type represented by the visual information of the road is town road, and another second state data is generated.
S206, generating a state data set.
It is to be explained that this refers to generating the state data set based on the first state data and the second state data. Illustratively, in some embodiments of the present application, the vehicle motion state includes a high vehicle speed state and a low vehicle speed state, the visual information of the road includes first road type state information and second road type state information, and the generated state data set may have four types.
S207, comparing the state data set with a preset data set in a database.
It should be noted that the database may be stored in a storage medium.
S208, judging whether a preset data set corresponding to the state data set is stored in the database.
S209, if yes, determining a corresponding preset data set, and judging the type of the road based on the preset data set corresponding to the state data set.
If not, return to steps S202 and S203. The database may not store the preset data set corresponding to the state data set, so that steps S202 and S203 are returned to continue to acquire the vehicle movement information and the visual information of the road, so as to avoid the error of the acquired information. For example, when the vehicle is traveling on a road with a low required vehicle speed, such as a curve road or town road, the vehicle speed sensor detects that the vehicle speed is high, and the database may not store the corresponding preset data set, steps S202 and S203 may be returned to acquire information again, so as to avoid error in acquiring the vehicle speed information or the visual information of the road. In the process, the illumination mode of the car lamp can be kept unchanged, and the car lamp can also be switched to a manual mode, so that a driver can select the illumination mode by himself.
Of course, in some embodiments of the present application, step 208 may not be provided, and referring to fig. 3, the preset data set stored in the database may be completely corresponding to the state data set one by one.
In this embodiment of the present invention, the generation of the first state data and the generation of the second state data may be independent of each other, for example, in a vehicle motion state having two states of a high vehicle speed and a low vehicle speed, the visual information of the road has a first road type state information and a second road type state information, and then the state data set has four different states. In this embodiment of the present application, the generation of the first state data and the generation of the second state data may not be independent of each other. For example, in some embodiments of the present application, please refer to fig. 4, fig. 4 is a flow chart illustrating the determination of the road type in some embodiments of the present application.
S301, starting the vehicle.
S302, motion information of a vehicle is acquired.
S303, road visual information in front of the vehicle is acquired.
S304, a judgment rule of the vehicle motion state is selected.
It should be noted that the determination rule for selecting the vehicle motion state based on the visual information of the road is referred to herein.
S305, judging the motion state of the vehicle.
It is to be noted that this refers to determining the vehicle motion state based on the state determination rule.
S306, determining the type of the road, it should be explained that the determination of the type of the road based on the vehicle motion state is referred to herein.
It will be appreciated that the vehicle motion state determination rule is selected based on the visual information of the road, i.e., the difference in the visual information of the road causes the determination rule of the vehicle motion state to be different. The following description is made with reference to specific examples.

The car light lighting system provided by the embodiment of the application can achieve the same technical effect, namely, can improve the accuracy of switching the lighting modes of the car light 4 because the car light lighting system is used for implementing the car light lighting method provided by the embodiment of the application. In some embodiments of the present application, a vehicle lamp lighting system includes a computer storage medium 2. The computer storage medium 2 has computer-executable instructions for execution by the processor 3 to implement the vehicle lamp lighting method provided in the embodiments of the present application.
In some embodiments of the present application, referring to fig. 10 to 13, the vehicle lamp 4 includes a light emitting member 41, a first lens 42 and a second lens 43. The light-emitting member 41 has a light-emitting surface; the first lens 42 is fixed relative to the light emitting element 41, and the first lens 42 is arranged relative to the light emitting surface along the first direction a; the second lens 43 can move relative to the first lens 42 according to the output signal of the processor 3 to be in a first position and a second position; wherein, in the case that the second lens 43 is in the first pose, the first lens 42 and the second lens 43 are disposed opposite to each other along the first direction a so that the vehicle lamp 4 is in an illumination mode; with the second lens 43 in the second position, the first lens 42 is offset from the second lens 43 in the first direction a to place the lamp 4 in another illumination mode.
According to the car lamp 4 provided by the embodiment of the application, under the condition that the second lens 43 is in the first pose, the first lens 42 is opposite to the second lens 43, and the light emitted by the light emitting element 41 can be irradiated into the external environment through the first lens 42 and the second lens 43, so that a lamplight effect is generated by the head lamp. When the second lens 43 is in the first position, the first lens 42 and the second lens 43 are staggered, that is, the light emitted by the light emitting element 41 passes through the first lens 42 and then does not pass through the second lens 43, so that another light effect is formed by the headlamp device. That is, the movement of the second lens 43 changes the propagation path of the light, thereby changing the illumination mode of the front lamp 4. Therefore, the headlamp of the embodiment of the application can realize the switching of the illumination mode only by controlling the movement of the second lens 43 according to the output signal of the processor 3, and the switching process is more convenient and the cost is lower.
Referring to fig. 10 to 13, in some embodiments of the present application, the vehicle lamp 4 may further include other lenses such as a third lens 44 and a fourth lens 45, and when the second lens 43 and the first lens 42 are offset in the first direction a, any one of the third lens 44 and the fourth lens 45 may be moved to a position opposite to the first lens 42, so as to generate a corresponding light effect on the vehicle lamp 4. Thus, each lens capable of moving to a position opposite to the first lens 42 can generate a corresponding light effect on the vehicle lamp 4, and a plurality of lenses can enable the vehicle lamp 4 to have various light effects, which is beneficial to enabling the vehicle lamp 4 to adapt to complex and changeable traffic conditions.
Of course, in some embodiments of the present application, where the second lens 43 is offset from the first lens 42, light may be transmitted through only the first lens 42, not through any other lens of the headlamp, to create a lighting effect.
The following describes a headlight as an example. Referring to fig. 10 to 13, in some embodiments of the present application, the vehicle lamp 4 includes a light emitting member 41, a first lens 42, a second lens 43, a third lens 44, a fourth lens 45, and a rotating motor 46. The second lens 43, the third lens 44 and the fourth lens 45 are all connected to the same rotating shaft, and the plurality of second lenses 43 are arranged along the circumferential direction of the rotating shaft, so that the first lens 42, the second lens 43, the third lens 44 and the fourth lens 45 can synchronously rotate when the rotating shaft rotates relative to the first lens 42 under the driving action of the rotating motor 46. In this way, when the illumination mode is switched, only one rotating motor 46 is needed for control, which is convenient.
The focal point of the second lens 43 in the first posture, the focal point of the third lens 44 in the first posture, and the focal point of the first lens 42 are aligned in the first direction a and aligned in the first direction a. The curvature of the second lens 43 is larger than that of the first lens 42, and the curvature of the third lens 44 is smaller than that of the first lens 42. The focal point of the fourth lens 45 in the first posture is spaced apart from the focal point of the first lens 42 in the second direction. The second lens 43, the third lens 44 and the fourth lens 45 can make the vehicle lamp 4 have four working illumination modes, which can be a normal illumination mode, a town illumination mode, a high-speed illumination mode and a turning illumination mode, respectively. Fig. 10 is a schematic structural view of a vehicle lamp in a normal lighting mode according to some embodiments of the present application, fig. 11 is a schematic structural view of a vehicle lamp in a town lighting mode according to some embodiments of the present application, fig. 12 is a schematic structural view of a vehicle lamp in a high-speed lighting mode according to some embodiments of the present application, and fig. 13 is a schematic structural view of a vehicle lamp in a turning lighting mode according to some embodiments of the present application.
Specifically, referring to fig. 10, when the vehicle lamp 4 is in the normal illumination mode, the second lens 43, the third lens 44 and the fourth lens 45 are staggered from the first lens 42 in the first direction a, and the light emitted from the light emitting surface only passes through the first lens 42, so that the vehicle lamp can be used for illumination of normal road conditions, and the light has both illumination length and illumination width.
Referring to fig. 11, when the lamp 4 is in town lighting mode, the second lens 43 and the first lens 42 are disposed opposite to each other along the first direction a, the curvature of the second lens 43 is larger than that of the first lens 42, and the irradiation length and the irradiation width of the light emitted from the lamp 4 are smaller, so that the user can better observe the road conditions at two sides, and effectively identify pedestrians, bicycles and animals at two sides of the road, thereby preventing sudden fleeing out to cause accidents.
Referring to fig. 12, when the lamp 4 is in the high-speed illumination mode, the third lens 44 and the first lens 42 are disposed opposite to each other along the first direction a, the curvature of the third lens 44 is smaller than that of the first lens 42, and the irradiation length and the irradiation width of the light emitted from the lamp 4 are larger, so that a user can recognize the road condition ahead in advance, effectively recognize the falling rocks, sundries and road blocks on the road ahead, and reserve sufficient time for avoiding the lane change of the vehicle.
Referring to fig. 13, when the lamp 4 is in the steering illumination mode, the fourth lens 45 and the first lens 42 are disposed opposite to each other along the first direction a, and the light emitted from the lamp 4 is guided by the fourth lens 45 to increase the illumination intensity on the steering side. So that the user can better observe the road condition at the steering side, effectively identify the road shoulder, the pothole or the obstacle at the near front side of the vehicle, and ensure that the user can better pass through the current road condition.
The foregoing is merely an embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think about changes or substitutions within the technical scope of the present application, and the changes or substitutions are covered in the protection scope of the present application.
