DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0021] In the related technology, when a vehicle equipped with a traditional autonomous driving camera enters or exits a tunnel, the light difference between inside and outside the tunnel is usually large, which will cause the camera's visual exposure to fail temporarily and cause blindness. As a result, the light of the image captured by the vehicle's visual image cannot transition smoothly, making the autonomous driving image algorithm unable to operate as expected, resulting in unstable control of the autonomous driving vehicle and a safety hazard during driving.

[0022] Therefore, the vehicle lighting control method of the embodiment of the present invention is adopted, by obtaining the driving state of the vehicle in the tunnel, the light difference of the vehicle entering or exiting the tunnel, and the driving time of the vehicle in the tunnel, and controlling the state of the lighting adjustment device according to the driving state, light difference and driving time, so as to achieve a smooth transition of light in the pictures collected by the visual image when the vehicle enters and exits the tunnel, thereby improving the stability, safety and user experience of autonomous driving.

[0023] The above-mentioned vehicle lighting control method is implemented based on the vehicle lighting control system. The vehicle lighting control system is described below by way of example.

[0025] It is understandable that when the vehicle is in the first entry / exit state and the second entry / exit state, when the value of MN or NM is less than 20lux, that is, when driving from a bright-light scene to a dim-light scene or from a dim-light scene to a bright-light scene, it is considered that the difference in light intensity is not large, and the fill light device or the shading device will not be turned on.

They are arranged at the tunnel exit and the upper side of the tunnel. They can detect the speed v of the autonomous driving vehicle before it enters the lane, calculate the average speed v, direction and distance s from the tunnel entrance in real time. At the same time, when the vehicle enters the tunnel or is about to exit the tunnel, it also monitors the vehicle speed in real time, calculates the average speed v, direction and distance from the tunnel entrance, and calculates the time t that the vehicle will take to enter or exit the tunnel, t=s / v; and transmits the information to the edge computing unit for edge processing, analysis and judgment; Edge computing unit 14: connected to the light sensors inside and outside the tunnel and the tunnel lidar, receives the light intensity values ​​"N" lux and "M" lux inside and outside the tunnel transmitted by them, compares the values ​​of M and N, determines the light difference between the light inside and outside the tunnel, and combines the time t when the autonomous driving vehicle is about to enter or exit the tunnel transmitted by the lidar, performs a logical judgment on the visual light compensation of the camera of the autonomous driving vehicle, and transmits the comparison results to the cloud platform for the cloud platform to control the fill light device and shading device of the autonomous driving camera; Cloud platform 15: receiving the light intensity in the tunnel transmitted by the edge computing unit and setting it to "N" lux and the light intensity outside the tunnel and setting it to "M" lux, and issuing instructions to control the fill light device and the light shielding device of the autonomous driving camera through comprehensive judgment, so as to ensure that the visual image acquisition of the camera is smooth and transitional, and avoid the occurrence of exposure blindness due to light differences; Roadside unit 16: arranged at the upper end of the tunnel entrance and exit, receives the compensation instruction for the visual light of the autonomous driving camera transmitted by the cloud platform, and transmits the instruction to the vehicle-mounted unit through wireless communication, so that the vehicle-side receives the instruction from the cloud platform to perform visual light compensation control for the camera; The vehicle-mounted unit 17 is arranged under the main driver's seat of the autonomous driving vehicle, receives the camera visual light compensation instruction transmitted by the roadside unit, and is used to compensate and control the light of the camera; Vehicle-side controller 18: arranged at the front end of the autonomous driving vehicle, connected to the vehicle-mounted unit, receives control instructions transmitted by the vehicle-mounted unit, and performs logical control on the fill light device and shading device around the camera; Fill light device 19: a ring structure, arranged around the front-view camera, composed of 8 fill lights, which can be divided into primary fill light according to fill light control: turn on 2 fill lights, secondary fill light, turn on 4 fill lights, and tertiary fill light, turn on 8 fill lights; Sunshade device 20: arranged around the front camera fill light device, composed of a sunshade, which is divided into first-level sunshade, the sunshade extends 30mm, second-level sunshade, the sunshade extends 60mm, and third-level sunshade, the sunshade extends 100mm according to different sunshade controls.

[0029] Based on the above, the following Figure 1-Figure 7 A vehicle lighting control method according to an embodiment of the present invention is described.

[0030] like Figure 2 FIG. 1 is a flow chart of a vehicle lighting control method according to an embodiment of the present invention. The vehicle lighting control method according to the embodiment of the present invention at least includes step S1 and step S2.

[0031] Step S1, obtaining the driving state of the vehicle in the tunnel, the light difference when the vehicle enters or exits the tunnel, and the driving time of the vehicle in the tunnel.

[0032] In an embodiment, Figure 3 As shown, the tunnel driving state is the state of a vehicle entering the tunnel from outside the tunnel, or the state of an external vehicle driving out of the tunnel from entering the tunnel, or the state of a vehicle having entered the tunnel, or the state of a vehicle having already driven out of the tunnel, which is obtained by the edge computing unit 14 receiving and calculating the state of the vehicle about to enter or exit the tunnel transmitted by the tunnel laser radar 13; the light difference is the value of MN or the value of NM, and the edge computing unit 14 receives the light intensity values ​​"N" lux and "M" lux inside and outside the tunnel transmitted by the light sensors inside and outside the tunnel, and compares the values ​​of M and N to obtain the difference; the driving time of the vehicle in the tunnel is the time before the vehicle enters the tunnel, or the time generated from the time when the vehicle enters the tunnel, or the time before the vehicle exits the tunnel, or the time generated from the time when the vehicle exits the tunnel, which is obtained by the edge computing unit 14 receiving and calculating the time when the vehicle is about to enter or exit the tunnel transmitted by the tunnel laser radar 13. By obtaining the vehicle's driving status in the tunnel, the light difference when the vehicle enters or exits the tunnel, and the vehicle's driving time in the tunnel, a data basis is provided for realizing vehicle shading or fill light control.

[0033] Step S2, controlling the state of the light adjustment device according to the driving state, the light difference and the driving time.

[0034] In an embodiment, the light adjustment device includes a light shielding device and a light filling device, such as Figure 1 As shown, the state of the lighting adjustment device is controlled according to the driving state, light difference and driving time. For example, the edge computing unit 14 determines the driving state, light difference and driving time of the vehicle to control the shading device or the fill-light device to perform corresponding levels of shading action or fill-light action, so as to achieve a smooth transition of light in the visual image collection when the vehicle drives from a strong light environment to a weak light environment or from a weak light environment to a strong light environment, thereby avoiding the problem of blindness caused by short-term visual exposure failure of the camera, and improving the stability, safety and user experience of autonomous driving.

[0035] According to the vehicle lighting control method of an embodiment of the present invention, by obtaining the driving state of the vehicle in the tunnel, the light difference when the vehicle enters or exits the tunnel, and the driving time of the vehicle in the tunnel, the state of the lighting adjustment device is controlled according to the driving state, light difference and driving time, so as to achieve a smooth transition of light in the pictures collected by the visual image when the vehicle enters and exits the tunnel, thereby improving the stability, safety and user experience of autonomous driving.

[0036] In some embodiments, the light difference includes a first light difference, and the state of the light adjustment device is controlled according to the driving state, the light difference and the driving time, including: when the vehicle is in a first entry state and the first light difference is greater than a preset light threshold and the driving time is a first preset time, the shading device in the light adjustment device is controlled to perform a first-level shading action; when the vehicle is in the first entry state and the first light difference is greater than the preset light threshold and the driving time is a second preset time, the shading device in the light adjustment device is controlled to perform a second-level shading action; when the vehicle is in the first entry state and the first light difference is greater than the preset light threshold and the driving time is a third preset time, the shading device in the light adjustment device is controlled to perform a third-level shading action.

[0037] In an embodiment, Figure 4 FIG. 1 is a schematic diagram of a light-filling device and a light-shielding device according to an embodiment of the present invention. Figure 6 FIG. 2 is a schematic diagram of a shading device according to an embodiment of the present invention. A front-view camera 25 is arranged at the front end of the front windshield of the vehicle, and is used to collect visual perception of the front of the automatic driving. A fill light device 19 and a shading device 20 are arranged around the front-view camera 25. The fill light device 19 and the shading device 20 can play a role in compensating the visual light of the front-view camera 25. Figure 4 The shading device 20 is arranged around the front view camera 25 fill light device 19, Figure 6 The shading hood 35 is arranged around the front-view camera 25 and can be extended. When shading, the shading hood 35 will extend outward to different distances according to different levels of instructions to play a shading role. According to different shading controls, it is divided into first-level shading, the shading hood 35 extends 30mm, second-level shading, the shading hood 35 extends 60mm, and third-level shading, the shading hood 35 extends 100mm. Figure 3, the light intensity in the tunnel is set to "N" lux and the light intensity outside the tunnel is set to "M" lux; the light difference is the difference between the light intensity in the tunnel and the light intensity outside the tunnel; the first light difference is the value of MN; the first entry state is the state of the vehicle entering the tunnel from outside the tunnel; the preset light threshold is the critical value for performing shading action obtained through requirements and experiments, and is set to 20lux; the first preset time, the second preset time and the third preset time are all the time before the vehicle enters the tunnel, which is the critical time for performing corresponding level of shading action obtained through requirements and experiments, and the first preset time is set to 5s; the second preset time is set to 3s; the third preset time is set to 1s.

[0038] When the state of the light adjustment device is controlled according to the driving state, the light difference and the driving time, the driving state of the vehicle is from outside the tunnel into the tunnel, and the value of MN is greater than 20lux, that is, from a scene with strong light to a scene with weak light, and 5s before the vehicle enters the tunnel, the shading device 20 is controlled to perform a first-level shading action, and the first-level shading action is that the shading hood 35 extends 30mm; then, 3s before the vehicle enters the tunnel, the shading device 20 is controlled to perform a second-level shading action, and the first-level shading action is that the shading hood 35 extends 60mm; then, 1s before the vehicle enters the tunnel, the shading device 20 is controlled to perform a third-level shading action, and the third-level shading action is that the shading hood 35 extends 100mm. By judging the first entry state, the first light difference and the driving time, different levels of shading actions are realized, thereby ensuring that the light of the visual image captured when the vehicle enters the tunnel from a strong light environment to a weak light environment is smoothly transitioned.

[0039] In some embodiments, the light difference includes a second light difference, and the state of the light adjustment device is controlled according to the driving state, the light difference and the driving time, including: when the vehicle is in a first exiting state and the second light difference is greater than a preset light threshold and the driving time is a first preset time, the shading device in the light adjustment device is controlled to perform a first-level shading action; when the vehicle is in the first exiting state and the second light difference is greater than the preset light threshold and the driving time is a second preset time, the shading device in the light adjustment device is controlled to perform a second-level shading action; when the vehicle is in the first exiting state and the second light difference is greater than the preset light threshold and the driving time is a third preset time, the shading device in the light adjustment device is controlled to perform a third-level shading action.

[0040] In an embodiment, in combination Figure 3 , Figure 4 and Figure 6 As shown, the first exit state is a state in which the vehicle exits the tunnel from inside the tunnel; and the second light difference is a value of NM.

[0041] When the state of the light adjustment device is controlled according to the driving state, the light difference and the driving time, the driving state of the vehicle is driving out of the tunnel, and the NM value is greater than 20lux, that is, driving from a scene with strong light to a scene with weak light, and 5s before the vehicle drives out of the tunnel, the shading device 20 is controlled to perform a first-level shading action, and the first-level shading action is that the shading hood 35 extends 30mm; then, 3s before the vehicle drives out of the tunnel, the shading device 20 is controlled to perform a second-level shading action, and the first-level shading action is that the shading hood 35 extends 60mm; then, 1s before the vehicle drives out of the tunnel, the shading device 20 is controlled to perform a third-level shading action, and the third-level shading action is that the shading hood 35 extends 100mm. By judging the first exit state, the second light difference and the driving time, different levels of shading actions are realized, thereby ensuring that when the vehicle drives out of the tunnel, the visual image captured when the vehicle drives from a strong light environment to a weak light environment has a smooth transition of light.

[0042] In some embodiments, after controlling the state of the light adjustment device according to the driving state, light difference and driving time, it also includes: when the vehicle is in the second driving-in state and the driving time is the third preset time, controlling the shading device in the light adjustment device to switch from the third-level shading action to the second-level shading action; when the vehicle is in the second driving-in state and the driving time is the second preset time, controlling the shading device in the light adjustment device to switch from the second-level shading action to the first-level shading action; when the vehicle is in the second driving-in state and the driving time is the first preset time, controlling the shading device in the light adjustment device to switch from the first-level shading action to the initial action.

[0043] In an embodiment, in combination Figure 3 , Figure 4 and Figure 6 As shown, the second entry state is the state where the vehicle has entered the tunnel from outside the tunnel; the third preset time, the second preset time and the first preset time are all the times when the vehicle needs to perform corresponding levels of shading actions from the start of entering the tunnel to continue driving. The third preset time is set to 1s, the second preset time is set to 3s and the first preset time is set to 5s.

[0044] After controlling the state of the lighting adjustment device according to the driving state, the light difference and the driving time, when the driving state of the vehicle is that it has entered the tunnel from outside the tunnel, and the time for continued driving from the time when the vehicle enters the tunnel is 1s, the shading device 20 is controlled to switch from the three-level shading in the above embodiment to the two-level shading, that is, the shading cover 35 is switched from extending 100mm to extending 60mm; then, when the time for continued driving from the time when the vehicle enters the tunnel is 3s, the shading device 20 is controlled to switch from the two-level shading to the one-level shading, that is, the shading cover 35 is switched from extending 60mm to extending 30mm; then, when the time for continued driving from the time when the vehicle enters the tunnel is 5s, the shading device 20 is controlled to switch from the one-level shading to the initial shading, that is, the shading cover 35 is switched from extending 30mm to the initial state before the shading cover performs the above-mentioned shading action, that is, the state of the shading cover is switched to the shading state before the vehicle enters the tunnel 5s and does not perform the first-level shading action. By judging the second entry state and driving time, different levels of shading recovery actions can be implemented to ensure that the initial shading state of the sunshade is restored when the vehicle enters the tunnel, thereby achieving a smooth transition of light in the visual image acquisition.

[0045] In some embodiments, after controlling the state of the light adjustment device according to the driving state, light difference and driving time, it also includes: when the vehicle is in the second exiting state and the driving time is the third preset time, controlling the shading device in the light adjustment device to switch from the third-level shading action to the second-level shading action; when the vehicle is in the second exiting state and the driving time is the second preset time, controlling the shading device in the light adjustment device to switch from the second-level shading action to the first-level shading action; when the vehicle is in the second exiting state and the driving time is the first preset time, controlling the shading device in the light adjustment device to switch from the first-level shading action to the initial action.

[0046] In an embodiment, in combination Figure 3 , Figure 4 and Figure 6As shown, the second exiting state is a state in which the vehicle has exited the tunnel from the tunnel. After controlling the state of the lighting adjustment device according to the driving state, the light difference and the driving time, when the driving state of the vehicle is that it has already driven out of the tunnel and the time for continued driving from the time when the vehicle drives out of the tunnel is 1 second, the shading device 20 is controlled to switch from the three-level shading in the above embodiment to the two-level shading, that is, the shading cover 35 is switched from extending 100 mm to extending 60 mm; then, when the time for continued driving from the time when the vehicle drives out of the tunnel is 3 seconds, the shading device 20 is controlled to switch from the two-level shading to the one-level shading, that is, the shading cover 35 is switched from extending 60 mm to extending 30 mm; then, when the time for continued driving from the time when the vehicle drives out of the tunnel is 5 seconds, the shading device 20 is controlled to switch from the one-level shading to the initial shading, that is, the shading cover 35 is switched from extending 30 mm to the initial state before the shading cover performs the above-mentioned shading action, that is, the state of the shading cover is switched to the shading state before the vehicle drives out of the tunnel 5 seconds before performing the first-level shading action. By judging the second exit state and driving time, different levels of shading recovery actions can be implemented to ensure that the initial shading state of the sunshade is restored when the vehicle exits the tunnel, thereby achieving a smooth transition of light in the visual image acquisition.

[0047] In some embodiments, the light difference includes a second light difference, and the state of the light adjustment device is controlled according to the driving state, the light difference and the driving time, including: when the vehicle is in a first entering state and the second light difference is greater than a preset light threshold and the driving time is a first preset time, the fill light device in the light adjustment device is controlled to perform a first-level fill light action; when the vehicle is in the first entering state and the second light difference is greater than the preset light threshold and the driving time is a second preset time, the fill light device in the light adjustment device is controlled to perform a second-level fill light action; when the vehicle is in the first entering state and the second light difference is greater than the preset light threshold and the driving time is a third preset time, the fill light device in the light adjustment device is controlled to perform a third-level fill light action.

[0048] In an embodiment, Figure 5 FIG. 1 is a schematic diagram of a fill light device according to an embodiment of the present invention. Figure 4 The fill light 30 is arranged in the annular circle of the fill light device 19, with a total of 8 fill lights, which are evenly distributed in the annular circle, and the brightness of each fill light is 3lux; it plays the role of fill light, and when the fill light device 19 turns on 2 fill lights, it is the first-level fill light, when turning on 4 fill lights, it is the second-level fill light, and when turning on 8 fill lights, it is the third-level fill light.

[0049] Combination Figure 3 and Figure 5As shown, when the state of the light adjustment device is controlled according to the driving state, the light difference and the driving time, the driving state of the vehicle is driving from outside the tunnel into the tunnel, and the difference of NM is greater than 20lux, that is, the scene of weak light enters the scene of strong light, and 5s before the vehicle enters the tunnel, the fill light device 19 is controlled to perform the first-level fill light action, and the first-level fill light action is to turn on 2 fill lights; then, 3s before the vehicle enters the tunnel, the fill light device 19 is controlled to perform the second-level fill light action, and the second-level fill light action is to turn on 4 fill lights; then, 1s before the vehicle enters the tunnel, the fill light device 19 is controlled to perform the third-level fill light action, and the third-level fill light action is to turn on 8 fill lights. By judging the first driving-in state, the second light difference and the driving time, different levels of fill light actions are realized, thereby ensuring that when the vehicle enters the tunnel, the light of the visual image captured when the vehicle enters the strong light environment from the weak light environment is smoothly transitioned.

By judging the second entry state and driving time, different levels of fill light recovery actions can be implemented to ensure that the initial fill light state of the fill light device is restored when the vehicle enters the tunnel, thereby achieving a smooth transition of the light of the visual image acquisition picture.

[0054] In some embodiments, after controlling the state of the lighting adjustment device according to the driving state, the light difference and the driving time, it also includes: when the vehicle is in the second exiting state and the driving time is a third preset time, controlling the fill light device in the lighting adjustment device to switch from the third-level fill light action to the second-level fill light action; when the vehicle is in the second exiting state and the driving time is the second preset time, controlling the fill light device in the lighting adjustment device to switch from the second-level fill light action to the first-level fill light action; when the vehicle is in the second exiting state and the driving time is the third preset time, controlling the fill light device in the lighting adjustment device to switch from the first-level fill light action to the initial fill light action.
