All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, shall fall within the scope of the present application.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the application described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
According to an embodiment of the present application, there is provided an embodiment of a control method for a high beam, it being noted that the steps shown in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases the steps shown or described may be performed in an order different from that herein.
Fig. 1 is a control method of a high beam according to an embodiment of the present application, as shown in fig. 1, the method includes the steps of:
step S102, determining the illumination intensity type of a target running area to which a target vehicle belongs;
In the technical solution provided in step S102 of the present application, the type of illumination intensity of the target driving area to which the target vehicle belongs may be determined, and it should be noted that the type of illumination intensity may include a plurality of types, for example, illumination is sufficient, illumination is insufficient, where illumination is sufficient may correspond to daytime and illumination is insufficient may correspond to night.
Optionally, the illumination intensity type may be determined by an optical sensor, or the image of the target area may be acquired by the image acquisition device, the image of the target area may be identified, and the illumination intensity type to which the target area belongs may be determined, for example, by identifying, whether the target area currently belongs to the daytime or the nighttime, further, the illumination intensity type may be determined by a time period, specifically, the current time is acquired, and the illumination intensity type is determined according to the current time.
Step S104, under the condition that the illumination intensity type is the target type, obtaining high-precision map data corresponding to the target driving area;
In the technical scheme provided in step S104 of the present application, high-precision map data of the target driving area can be obtained when the illumination intensity type is the target type.
For example, in the case where the illumination intensity type is poor in illumination intensity (for example, at night), the high-precision map data of the target area is acquired from the server, it is understood that the high-precision map in the present application may be stored locally in the vehicle due to the poor communication network of some road sections, that is, the high-precision map data of the target area may be acquired from the high-precision map stored locally in the vehicle under the poor condition through the network. It is easy to note that in the case where the illumination intensity type is good in illumination intensity (e.g., daytime), it may not be necessary to acquire high-precision map data.
The high-precision map data in the present application is derived from a high-precision map, which is actually a dedicated map serving an autopilot system in comparison with a general navigation electronic map (also referred to as a high-precision map), and the high-precision map is also referred to as an autopilot map or a high-resolution map, and is a new map data pattern for an autopilot vehicle. The absolute position precision of the high-precision map is close to 1m, and the relative position precision is in the centimeter level, and can reach 10 cm to 20cm. In addition, the high-precision map can accurately and comprehensively represent road characteristics and has higher real-time performance, and in addition, the high-precision map can also record specific details of driving behaviors, including typical driving behaviors, optimal acceleration points and braking points, road condition complexity, labels of signal receiving conditions of different road segments and the like.
Step S106, at least determining the road type of the target driving area based on the high-precision map data;
In the technical solution provided in step S106 of the present application, at least the road type of the target driving area may be obtained based on the high-precision map data, and it should be noted that, in the case where the high-precision map is the origin server, other road information besides the road type, for example, driving tracks of other vehicles in the target area, tracks of pedestrians, and arrangement information of other building diagrams of the target area may also be obtained.
Step S108, collecting surrounding environment image data of the target vehicle;
In the technical scheme provided in the step S106 of the present application, the image data of the surrounding environment of the target vehicle can be collected by the image collecting devices such as the camera and the radar, so as to determine the display mode of the high beam in combination with the road type.
It should be noted that, the above camera includes but is not limited to: monocular cameras, and binocular cameras, including but not limited to: the laser radar, the millimeter wave radar, the camera and the radar may be plural and may be installed at different positions of the vehicle, for example, at the head, the tail and the roof, respectively.
Alternatively, the ambient image data may also be acquired from an image acquisition device mounted in the target area, for example, by cameras or monitoring probes disposed on both sides of the road.
Step S110, a display mode of a high beam of the target vehicle is generated according to the road type and the surrounding environment image data.
In the technical scheme provided in the step S110 of the present application, the display mode of the high beam of the target vehicle can be generated by combining the road type and the image data of the surrounding environment, and compared with the mode of determining the control strategy of the high beam based on the image data in the related art, the technical scheme provided in the present application can determine the road type of the target area based on the image data of the surrounding environment, thereby determining the display mode of the high beam.
Through the technical scheme from step S102 to step S110, the illumination intensity type of the target traveling area to which the target vehicle belongs is determined, high-precision data corresponding to the target traveling area is obtained under the condition that the illumination intensity type is the target type, the road type of the target traveling area is determined based on the high-precision map data, then, surrounding environment image data of the target vehicle is collected, finally, the display mode of the high beam of the target vehicle is generated based on the road type and the surrounding environment data, and finally, the purpose of controlling the high beam based on the road type and the surrounding environment data of the vehicle is achieved, so that the display mode of the high beam is accurately controlled, the technical effects of avoiding interference with the sight of other traveling vehicles and reducing the occurrence frequency of traffic accidents are achieved, and the technical problems that the display mode of the high beam is unreasonable, the normal traveling of the vehicle is affected, and the traffic accidents are easily caused due to the fact that the illumination intensity is poor, the road image information acquired based on a camera in the related technology are solved.
As an alternative embodiment, the display mode of the high beam of the target vehicle generated according to the road type and the surrounding environment image data may be implemented by the following modes: determining whether other moving vehicles exist in a preset surrounding range of the target vehicle according to the surrounding environment image data; and in the case that other moving vehicles exist in the preset peripheral range of the target vehicle, at least determining the relative distance between the other moving vehicles and the target vehicle, and determining the first irradiation range of the high beam according to the relative distance and the road type. The predetermined peripheral range may be an area having a radius of 70 meters with respect to the center of the target vehicle, and the irradiation range of the high beam may be determined according to the relative distance and the road type in the case where it is determined that other moving vehicles exist in the predetermined peripheral range of the target vehicle based on the surrounding environment image data.
Specifically, determining whether other moving vehicles exist in the preset peripheral range of the target vehicle according to the surrounding environment image data can be achieved by the following steps: detecting whether image data of a predetermined shape exists in surrounding environment image data, wherein the predetermined shape includes: a vehicle headlight shape, or a vehicle taillight shape; in the case that the surrounding environment image data has image data of a predetermined shape, determining that other moving vehicles exist in a preset surrounding area of the target vehicle; in the case where the surrounding environment image data does not have image data of a predetermined shape, it is determined that no other moving vehicle exists within a preset surrounding range of the target vehicle. That is, in the case where there is a vehicle headlight or a vehicle tail lamp around the target vehicle, it is determined that there is another moving vehicle around the target vehicle.
In some examples of the present application, determining a first irradiation range of the high beam according to the relative distance and the road type includes: and under the condition that the road type is determined to be a curve type, adjusting the current state of the high beam lamp to be an operation state corresponding to the low beam lamp, wherein the curve type comprises one of the following components: right angle bend and S-bend; under the condition that the road type is determined to be a non-curve type, acquiring an effective adjusting range of the high beam; controlling the light distance of the high beam to be smaller than a preset threshold under the condition that the relative distance is within an effective adjusting range, wherein the preset threshold is determined according to the visual field range of the target object in other moving vehicles; and under the condition that the relative distance does not belong to the effective adjusting range, adjusting the current running state of the high beam lamp to the running state corresponding to the low beam lamp. That is, in the case where the road type is a right angle bend or an S-bend, the high beam is directly adjusted to the low beam, and in the case where the road type is a non-bend, the effective adjustment range of the high beam is obtained, for example, the effective adjustment range of the high beam is 100 to 200 meters, and in the case where the relative distance is 120 meters, the light distance of the high beam is controlled to 140 meters, and it is noted that the 140 meters is a distance that does not affect the visual field of other vehicle drivers. For another example, the effective adjusting range of the high beam is 100-200 meters, and in the case that the relative distance is 80 meters, the light distance of the high beam is directly set as the irradiation distance of the low beam because the light distance of the high beam cannot be set within 80 meters anyway.
As an alternative embodiment, in the case where no other moving vehicle is present in the predetermined peripheral range of the target vehicle, the traveling direction of the target vehicle is determined, and the second irradiation range of the high beam is determined according to the traveling direction and the road type.
Specifically, the determination of the second irradiation range of the high beam according to the traveling direction and the road type can be achieved by: predicting a driving track of a target vehicle along a driving direction; obtaining a dangerous driving area of the target vehicle in the driving process according to the predicted driving track and the road type; the second irradiation range is determined according to the dangerous driving area.
In some embodiments of the present application, determining the type of illumination intensity of the target driving area to which the target vehicle belongs may be implemented by, specifically, acquiring environmental image data of the target driving area; recognizing environment image data, and determining the illumination intensity type according to the recognition result of the image data; or acquiring the current running time of the target vehicle, and determining the illumination intensity type according to the running time, wherein the illumination intensity type is used for indicating whether high-precision image data are required to be acquired when determining the display mode of the high-beam, namely whether the display mode of the high-beam is required to be determined by combining the road type and the surrounding environment image data, or whether the display mode of the high-beam can be determined only based on the surrounding environment image data.
Optionally, determining the illumination intensity type according to the driving time includes: determining a target period corresponding to the driving time; and acquiring the illumination intensity level corresponding to the target period, and according to the illumination intensity type of the illumination intensity level. For example, if the current driving time is 20:00, it may be determined that the target period corresponding to the driving time is a night period, and then it may be determined that the illumination intensity type is an illumination intensity difference.
The above technical solution of this embodiment is further exemplified below.
In this embodiment, the road condition of the current vehicle driving road section is identified through the high-precision map, and then the irradiation range of the high beam is automatically adjusted by combining the information of the vehicle and other vehicles, so as to achieve the purpose of anti-dazzle control, thereby reducing the occurrence rate of safety accidents, and specifically comprising the following steps:
the first step: judging whether the ambient light is sufficient or not in daytime or at night and according to the self-light-sensing sensor, and if the ambient light is insufficient in the daytime or at night, requesting a user to turn on an intelligent high beam system;
and a second step of: the current driving road condition is determined according to the high-precision map, and fig. 2 is a road type in the embodiment, as shown in fig. 2.
And a third step of: the required information is obtained from structured data provided by the high-precision map, for example: road geometry, lane width, grade, curvature, and lane start and end distance, for example, in fig. 2a and b require high precision maps to provide real-time curvature, and c, d, and e require lanes to be provided in which the vehicle is currently traveling.
Fourth step: it may be assumed that the road types in fig. 2 are all the cases without other vehicles, and a and b in fig. 2 need to control the irradiation range of the high beam in combination with curvature information provided by the high-precision map so that the irradiation range of the high beam irradiates as much as possible the road condition inside the curve, as shown by a and b in fig. 3.
C, d and e in fig. 2 need to be comprehensively analyzed in combination with the position information of the vehicle and the road type provided by the high-precision map, if the vehicle is driven to the intersection and turns left, turns around or goes straight in the rightmost lane, the irradiation range of the high beam is distributed to the intersections on the left and right sides as much as possible, and the road condition and the vehicle condition on the left and right sides are maximally irradiated, as shown in c and e in fig. 3; if the vehicle is traveling to the intersection and turns right in the rightmost lane, it is necessary to adjust the irradiation range of the high beam as much as possible to the right-side intersection as shown by d in fig. 3; if the vehicle is traveling to the T-intersection and turns right in the rightmost lane, it is necessary to adjust the high beam irradiation range to the right-side intersection to the maximum extent, as indicated by f in fig. 3. If the vehicle runs to the ramp and directly moves in the rightmost lane or enters the ramp entrance, the irradiation range of the high beam needs to be adjusted to the ramp to the greatest extent, and the sudden occurrence of the vehicle in the ramp is prevented, as shown by g, h and i in fig. 3; if the vehicle exits the ramp exit, the irradiation range of the high beam needs to be adjusted to the left side of the ramp exit direction as much as possible so as to prevent the sight from being blocked by the obstacle during driving, and the vehicle or the pedestrian is suddenly flushed out from the rear of the obstacle to generate traffic accidents, and the control condition of the high beam is shown as j in fig. 3.
Fifth step: the high beam control needs to be adjusted in advance according to the road type provided by the high-precision map, then other vehicle position information, direction information and the like are estimated according to the vehicle head lamp or tail lamp information identified by the camera, and then other vehicle judgment is carried out. If the camera recognizes that the vehicle is a headlight, the situation that the vehicle and other vehicles meet is indicated, otherwise, the situation is a following situation, and the situation is specifically shown in fig. 4.
Sixth step: identifying the head lamp or tail lamp conditions of other vehicles according to the conditions shown in fig. 4, and adjusting the light to avoid the visual field range of drivers of other vehicles if the other vehicles are in the effective adjustment range of the high beam; if the effective adjusting range of the high beam is exceeded, the high beam is directly adjusted to the low beam. In all road types of fig. 3, if other vehicles are stably running in front of the front, the high beam needs to be adjusted to the low beam. If the other vehicles in fig. 3 are all within the adjustment range of the high beam, the adjustment is performed according to the control strategy of fig. 5. In fig. 5a and b, other vehicles all run in a narrower curve, and the high beam needs to be adjusted to the low beam at the moment, so that the anti-dazzle function is achieved; c. d, e, f, g, i, j and k will make a high beam adjustment according to the road type and other vehicle locations provided by the high precision map, minimizing the impact of the high beam on the driver.
It is easy to note that, according to the road type provided by the high-precision map and the sensing condition of the camera to the lamps of other vehicles, the specific algorithm flow of the high beam control can be performed according to the flow shown in fig. 6.
In this example, first, the ambient light information can be determined by means of the own sensor, if the night is recognized and the ambient light is dark, the road condition information of the current vehicle running is obtained through the high-precision map, and if the moving vehicle is not present, the irradiation range of the high beam needs to be adjusted according to the running direction of the own vehicle, so that the dangerous area is irradiated as much as possible, and the sudden occurrence of the danger is prevented.
