[0078] The embodiment of the present application provides a vehicle warning light adjustment method, an adjustment system, a vehicle and a storage medium. The vehicle warning light adjustment method includes: detecting environmental data of the vehicle environment; controlling the vehicle warning light to display in different modes according to the environmental data; detecting the current vehicle state of the vehicle; and adjusting the display distance and display direction of the vehicle warning light according to the current vehicle state of the vehicle.

[0079] The vehicle warning light adjustment method, adjustment system, automobile and storage medium of the embodiments of the present application. The vehicle warning light adjustment method detects the environmental data of the vehicle's environment and the vehicle's current vehicle status, and then controls the vehicle warning light to display in different modes according to the environmental data, and adjusts the display distance and display direction of the vehicle warning light according to the vehicle's current vehicle status. In this way, the display mode, display distance and display direction of the vehicle warning light are adaptively adjusted according to different environmental data and the different current states of the vehicle, so that the warning effect is obvious, the attention is increased, and the risk of accidents is reduced.

[0080] Figure 1 FIG. 1 is a flow chart of an embodiment of a vehicle warning light adjustment method of the present application. Figure 1 As shown, the vehicle warning light adjustment method includes steps S1 to S4.

[0081] Step S1, detecting environmental data of the environment in which the vehicle is located. In this embodiment, a vehicle perimeter camera is provided in the vehicle. The vehicle perimeter camera is used to detect environmental data of the environment in which the vehicle is located.

[0082] Step S2: Control the vehicle warning light to display in different modes according to the environmental data. In this embodiment, the two-dimensional mode and / or three-dimensional mode can be selected for display according to the actual environmental data.

[0083] Step S3, detecting the current vehicle state of the vehicle. In this embodiment, an inertial navigation sensor is provided in the vehicle. The inertial navigation sensor is used to detect the vehicle's tilt angle in the X / Y / Z directions and the acceleration of each axis, and the current vehicle state of the vehicle is determined based on the above information.

[0084] Step S4: adjusting the display distance and display direction of the vehicle warning light according to the current vehicle state of the vehicle. In this embodiment, the display distance and display direction of the vehicle warning light can be adaptively adjusted according to the actual vehicle state of the vehicle.

[0085] The vehicle warning light adjustment method of the embodiment of the present application detects the environmental data of the environment in which the vehicle is located and the current vehicle state of the vehicle, and then controls the vehicle warning light to display in different modes according to the environmental data, and adaptively adjusts the display distance and display direction of the vehicle warning light according to the current vehicle state of the vehicle. For example, when the vehicle is outdoors and there are people in the vehicle, the vehicle surrounding environmental data will be continuously detected, and the vehicle warning light will be actively activated and displayed in different modes based on the different environmental data detected. The display distance and display direction of the vehicle warning light can also be adaptively adjusted according to the different current states of the vehicle detected, so that the warning effect is obvious, attention is increased, and the risk of accidents is reduced.

[0086] Figure 2 Shown Figure 1 A flowchart of an embodiment of the vehicle warning light adjustment method from step S1 to step S2 is shown. Figure 2 As shown, step S1 includes step S11, and step S2 includes step S21. In this embodiment, the environmental data includes weather data. The weather data includes rain or snow or hail. In some other embodiments, the weather data also includes other complex weather data.

[0087] Step S11, detecting the flow of rain, snow or hail in the environment where the vehicle is located. In this embodiment, the real-time amount of rain, snow or hail in the environment where the vehicle is located is detected by using a sensor around the vehicle.

[0088] Step S21: When it is detected that the flow of rain, snow or hail reaches the corresponding threshold, the vehicle warning light is controlled to be displayed in a two-dimensional mode. In this embodiment, a rain threshold, a snow threshold or a hail threshold is preset. The detected real-time rain, snow or hail is compared with the preset rain threshold, snow threshold or hail threshold, and the weather condition of the vehicle's current environment is determined according to the comparison result, so as to actively activate the vehicle warning light according to the actual weather condition and display it in a two-dimensional mode, so as to enhance the warning effect, increase attention and reduce the risk of accidents.

[0089] In some embodiments, when rain is detected, the detected real-time rainfall is compared with a preset rainfall threshold. When the real-time rainfall reaches the rainfall threshold, it indicates that the vehicle is in a heavy rainy environment at this time. The vehicle warning light is actively activated, and the vehicle warning light is displayed in a two-dimensional mode, so that the warning effect is obvious, attention is increased, and the risk of accidents is reduced. Similarly, when snow is detected, the detected real-time snow volume is compared with a preset snow volume threshold. When the real-time snow volume reaches the snow volume threshold, it indicates that the vehicle is in a heavy snowy environment at this time. The vehicle warning light is actively activated, and the vehicle warning light is displayed in a two-dimensional mode, so that the warning effect is obvious, attention is increased, and the risk of accidents is reduced. When hail is detected, the detected real-time hail volume is compared with a preset hail volume threshold. When the real-time hail volume reaches the hail volume threshold, it indicates that the vehicle is in a heavy haily environment at this time. The vehicle warning light is actively activated, and the vehicle warning light is displayed in a two-dimensional mode, so that the warning effect is obvious, attention is increased, and the risk of accidents is reduced. In some embodiments, when rain or snow weather of a specific density (the specific density can be modified by the user) or complex weather of rain, snow, or hail is detected, the two-dimensional vehicle warning lights (double flash lights) can be actively activated to avoid driving safety factors caused by nervousness / searching for warning lights during driving.

[0090] Figure 3 Shown Figure 1Flow chart of another embodiment of the vehicle warning light adjustment method from step S1 to step S2. Figure 3 As shown, step S1 includes step S12, and step S2 includes step S22. In this embodiment, the environmental data includes visibility data. The visibility data includes visible distance.

[0091] Step S12, detecting the visible distance of the environment in which the vehicle is located. In this embodiment, a visible light camera / TOF camera, a millimeter wave radar, and an ultrasonic radar are provided in the vehicle. At least one of the visible light camera / TOF camera, the millimeter wave radar, and the ultrasonic radar is used to detect the real-time visible distance of the environment in which the vehicle is located.

[0092] Step S22, when it is detected that the visible distance is less than the visible distance threshold, the vehicle warning light is controlled to be displayed in a three-dimensional mode. In this embodiment, a visible distance threshold is preset. The real-time visible distance detected is compared with the preset visible distance threshold, and the visibility of the vehicle's current environment is determined according to the comparison result, so that according to the visibility data, the vehicle warning light is actively activated and displayed in a two-dimensional mode, thereby enhancing the warning effect, increasing attention, and reducing the risk of accidents. In this embodiment, at least one of a visible light camera / TOF camera, a millimeter wave radar, and an ultrasonic radar is used to comprehensively determine the real-time visible distance of the vehicle's environment. If it is detected that the real-time visible distance is less than the visible distance threshold, the vehicle warning light is actively activated and displayed in a three-dimensional mode, thereby enhancing the warning effect, increasing attention, and reducing the risk of accidents.

[0093] In step S22, the vehicle warning light is controlled to be displayed in a three-dimensional mode and displayed at a preset position on the side of the vehicle, and perpendicular to the horizontal plane. In this embodiment, a holographic grating module is provided in the vehicle. The spatial position characteristics of the corresponding target are recorded in the holographic grating module during the exposure process using the holographic grating module. During the projection process, the holographic grating module is illuminated by a light source, and the virtual image of the original target can be effectively seen. The virtual image of the original target can be a three-dimensional virtual image of the vehicle warning light. The three-dimensional virtual image of the vehicle warning light is located at a preset position on the side of the vehicle, and the preset position is generally fixed. And the three-dimensional vehicle warning light is projected in a plane perpendicular to the ground, so that the warning effect is obvious and the attention is increased. For vehicles coming from the same direction, in a driving environment with poor visibility, the vehicle warning light can be observed first at a position farther away from the vehicle, and a safe distance can be maintained to reduce the risk of accidents.

[0094] Figure 4 Shown Figure 1 The flowchart of an embodiment of the vehicle warning light adjustment method from step S3 to step S4 is shown. Figure 4 As shown, step S3 includes step S31, and step S4 includes step S41.

[0095] Step S31, detecting that the vehicle is currently in a driving state. In this embodiment, when the inertial navigation sensor detects that the speed and acceleration of the vehicle are both greater than 0, it is determined that the vehicle is currently in a driving state.

[0096] Step S41, when it is detected that the vehicle is currently in a driving state, determine whether the road on which the vehicle is traveling has road markings. Wherein, when it is determined that the road on which the vehicle is traveling has road markings, the display direction of the vehicle warning light is adjusted to be in the opposite direction of the vehicle's driving direction, and the display distance on both sides of the vehicle does not exceed the edge of the lane where the vehicle is located. In this embodiment, when it is detected that the vehicle is currently in a driving state, it is further identified that the vehicle is driving on a road section with road markings, and the vehicle warning light is not activated in the vehicle's forward direction, but is activated in the opposite position of the driving direction, and the vehicle warning light is displayed in a three-dimensional mode. The display distance on both sides of the vehicle does not exceed the edge of the lane where the vehicle is located, and according to the specific position, the characteristic emission angle (not exceeding one lane) allows the three-dimensional warning light to meet the user's adjustment, and will not affect the vehicles in other lanes, thereby reducing the risk of accidents.

[0097] exist Figure 4 In the illustrated embodiment, after detecting that the vehicle is currently in a driving state, the vehicle warning light adjustment method further includes steps S51 to S61. Step S51 is executed after step S31.

[0098] Step S51, detecting the road surface information of the road on which the vehicle is traveling. In this embodiment, a camera is used to detect the real-time road surface information of the road on which the vehicle is traveling. The road surface information may be features such as ice, snow, and long water surface.

[0099] Step S61, according to the road surface information of the road on which the vehicle is traveling, the display distance and display direction of the vehicle warning light are adjusted. In this embodiment, pictures of features such as ice, snow, and long water surface are pre-stored. During the driving process of the vehicle, if the real-time road surface information detected by the camera is compared with the pre-stored pictures to determine whether there are ice, snow, and long water surface features on the road surface, the display distance and display direction of the vehicle warning light are adjusted, so as to enhance the warning effect and increase the attention, thereby timely reminding the user to reduce the speed, reminding the driver of the vehicle and the surrounding vehicles to pay attention to driving safety and keep a distance.

[0100] Figure 5 Shown Figure 1 Flow chart of another embodiment of the vehicle warning light adjustment method from step S3 to step S4. Figure 5 As shown, step S3 includes step S32, and step S4 includes step S42.

[0101] Step S32, detecting that the vehicle is currently in a stopped state. In this embodiment, when the inertial navigation sensor detects that the speed and acceleration of the vehicle are both 0, it is determined that the vehicle is currently in a stopped state.

[0102] Step S42: when it is detected that the vehicle is currently in a stopped state, determine whether the road on which the vehicle is traveling has road markings; wherein, when it is determined that the road on which the vehicle is traveling has road markings, adjust the display brightness of the vehicle warning light to the maximum brightness, and the display distance to the maximum display distance, and issue a warning message, the warning message including voice warning information and / or text warning information. In this embodiment, when it is detected that the vehicle is currently in a stopped state, it is further identified that the vehicle is traveling on a road section with road markings, and the three-dimensional mode vehicle warning light is activated. At this time, the display brightness of the vehicle warning light is adjusted to the maximum brightness, and the display distance is the maximum display distance, and a warning message is issued, the warning message can be text and / or voice, so as to enhance the information transmission capability, strengthen the warning effect, improve the attention, and reduce the risk of accidents.

[0103] exist Figure 5 In the illustrated embodiment, after detecting that the vehicle is currently in a stopped state, the vehicle warning light adjustment method further includes steps S52 to S62. Step S52 is executed after step S32.

[0104] Step S52, detecting the current lane information where the vehicle is parked. In this embodiment, if it is detected that the vehicle is currently in a stopped state, the camera is further used to detect the current lane information where the vehicle is parked. The current lane information may be the specific lane where the vehicle is currently parked, such as the left lane, the middle lane, or the right lane.

[0105] Step S62: Based on the current lane information where the vehicle is parked, indication information indicating that the vehicle should avoid the current lane information and drive toward the adjacent lane is indicated. In this embodiment, based on the specific lane information, indication information indicating that the vehicle should drive toward the adjacent lane is given, and the indication information may be an arrow indication. For example, if the specific lane where the vehicle is parked is identified as lane 1, the holographic grating module is used to project arrow indication information pointing to lane 2 or lane 3 behind the vehicle, and the arrow indication information may be a suggested avoidance direction for vehicles coming from behind to reduce the risk of accidents.

[0106] exist Figure 5 In the illustrated embodiment, after detecting that the vehicle is currently in a stopped state, the vehicle warning light adjustment method further includes steps S53 to S63.

[0107] Step S53, detecting the topographic information of the road where the vehicle is parked. In this embodiment, if it is detected that the vehicle is currently in a stopped state, the camera is further used to detect the real-time topographic information of the road where the vehicle is parked, and the topographic information may be the ground topography.

[0108] Step S63, according to the terrain information, determine the terrain flatness of the surrounding side of the vehicle. Wherein, when it is determined that the terrain flatness of the surrounding side of the vehicle exceeds the flatness threshold, a prompt information for indicating avoiding the terrain is indicated. In this embodiment, the terrain flatness threshold of the road where the vehicle is parked is pre-stored. According to the specific real-time terrain information, the real-time terrain flatness of the surrounding side of the vehicle is determined and compared with the pre-stored flatness threshold. When the real-time terrain flatness is greater than the flatness threshold, it means that the terrain where the vehicle is located is uneven at this time, and a safety instruction needs to be given. The flatness threshold here can be positive (higher than the plane) and reverse (lower than the plane). For example, when the vehicle is parked on a mountain road and the side is a mountain wall or a valley, a holographic grating module is used to project a prompt information for pointing to avoid the mountain wall or valley at the rear of the vehicle, thereby giving a driving suggestion in a safe direction to remind the rear driving safety, enhance the warning effect, and increase attention.

[0109] In this embodiment, when the vehicle warning lights are displayed in three-dimensional mode, if it is recognized that the display distance, display position, display angle and size are inappropriate, they can also be adjusted manually. In this embodiment, the display distance, display position, display angle and size of the vehicle warning lights in three-dimensional mode are adaptively adjusted through the adjustment function of the vehicle's central control setting, and the adjustment is more flexible.

[0110] Figure 6 Shown Figure 1 A flow chart of another embodiment of a vehicle warning light adjustment method is shown in FIG. Figure 6 As shown, the vehicle warning light adjustment method further includes steps S7 to S8.

[0111] Step S7, detecting the illumination information of the environment where the vehicle is located. In this embodiment, an illumination sensor and a light color sensor are provided in the vehicle. The illumination sensor is used to detect the real-time illumination intensity of the environment where the vehicle is located. The light color sensor is used to detect the real-time ambient light color of the environment where the vehicle is located.

[0112] Step S8: Adjust the display brightness or display color of the vehicle warning light according to the illumination information of the environment in which the vehicle is located. In this embodiment, the display brightness or display color of the vehicle warning light is adjusted according to the detected real-time illumination intensity and real-time ambient light color to enhance the warning effect and improve the attention. In this embodiment, the display brightness or display color of the two-dimensional or three-dimensional vehicle warning light is adjusted.

[0113] Figure 7Shown Figure 6 FIG. 1 is a flow chart of an embodiment of the vehicle warning light adjustment method from step S7 to step S8. Figure 7 As shown, step S7 includes step S71, and step S8 includes step S81. In this embodiment, the illumination information includes illumination intensity.

[0114] Step S71, detecting the light intensity in different directions of the environment where the vehicle is located. In this embodiment, an illumination sensor is used to detect the real-time light intensity in different directions of the environment where the vehicle is located.

[0115] Step S81, when the illumination intensity in different directions of the environment in which the vehicle is located reaches the intensity threshold, the vehicle warning light is controlled to be displayed in two-dimensional mode and three-dimensional mode, and the display brightness is adjusted to the maximum value. In this embodiment, after the illumination intensity in different directions around the vehicle is detected by the illumination sensor, when the vehicle 3D lighting application is activated, the light brightness displayed in the same direction will be adaptively adjusted based on the light intensity data detected in the corresponding direction to reasonably control the energy consumption of the whole vehicle. For example, in a darker environment (the vehicle is parked in the basement), the display brightness of the vehicle warning light is controlled to be in a darker state. In a brighter environment, the display brightness of the vehicle warning light is controlled to be in a high-brightness state to ensure the contrast of the prompt information and the effectiveness of personnel's attention. After detecting the illumination intensity and direction, the display brightness, display angle, display distance, display image size, and display clarity of the vehicle warning light will be adaptively adjusted to reasonably control energy consumption on the basis of meeting regulatory requirements. When the illumination intensity is greater than the intensity threshold, the two-dimensional mode and three-dimensional mode display are activated at the same time to increase the attention of outsiders.

[0116] Figure 8 Shown Figure 6 Flow chart of another embodiment of the vehicle warning light adjustment method from step S7 to step S8. Figure 8 As shown, step S7 includes step S72, and step S8 includes step S82. In this embodiment, the illumination information includes the color temperature of the ambient light.

[0117] Step S72, detecting the color temperature of the ambient light in the environment where the vehicle is located. In this embodiment, a light color sensor is used to detect the color temperature of the ambient light in the environment where the vehicle is located. The color temperature of the ambient light refers to the characteristics of the color of the light source perceived by the human eye, usually expressed in Kelvin (K). The unit of color temperature is Kelvin, which is used to describe the color of the light emitted by the light source, from lower values ​​representing warmer light to higher values ​​representing cooler light.

[0118] Step S82: According to the color temperature of the ambient light in the environment where the vehicle is located, the display color of the vehicle warning light is adjusted to a color that is complementary to the color temperature of the ambient light in the environment where the vehicle is located. After detecting the color temperature characteristics of the ambient light, the display color of the vehicle warning light is adaptively adjusted. For example, for the evening when the ambient color temperature is high (red) and the noon when the ambient color temperature is low (blue), the display color of the vehicle warning light is adjusted to a complementary color. The complementary color can be obtained through a color temperature table to enhance the contrast chromaticity, enhance the effectiveness of the prompt information in the background environment, and make the warning effect obvious.
