Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of methods and apparatus consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Before introducing the vehicle warning light control method, device and vehicle provided by the present disclosure, an application scenario related to various embodiments of the present disclosure is first introduced. The application scene can comprise a vehicle and a rear vehicle which runs behind the vehicle, an angle-adjustable prompting lamp is arranged behind the vehicle, the vehicle and the rear vehicle can be automobiles, but are not limited to traditional automobiles, pure electric automobiles or hybrid automobiles, and besides, the control method and the device of the vehicle prompting lamp provided by the disclosure can also be suitable for other types of automobiles or non-automobiles.
FIG. 1 is a flow chart illustrating a method of controlling a vehicle notification light, as shown in FIG. 1, according to an exemplary embodiment, including the steps of:
And 102, determining a target angle according to the running speed.
For example, the vehicle state data may be obtained in real time by a controller of the vehicle while the vehicle is traveling on a road surface. The controller may be an MCU (micro Control Unit, chinese), an ECU (Electronic Control Unit, chinese), a BCM (Body Control Module, chinese), and the like, and the disclosure is not limited thereto. The state data may include the driving speed of the vehicle, and may also include weather information, road condition information, brightness information, and the like corresponding to the current driving environment of the vehicle. The weather information, the road condition information, and the brightness information may be acquired by, for example, a humidity sensor, a drive recorder, a forward-looking camera, a light sensor, and the like provided on the vehicle. The humidity sensor may be a ceramic, organic polymer, semiconductor, electrolyte, or the like type sensor. The photometric sensor can be a rainfall illumination sensor, a fiber optic photosensor, a color sensor, a photoresistor, and the like. After acquiring the status data, the target angle may be determined based on the travel speed in the status data. For example, the corresponding relationship between the driving speed and the angle of the indicator light may be stored in a preset relationship table (e.g., relationship table a), and then the target angle corresponding to the driving speed may be determined by looking up the relationship table. In another implementation, the driving speed may also be input into a pre-established angle determination function or angle determination model, and the target angle is determined through the angle determination function or angle determination model, which is not specifically limited in this disclosure.
And 103, controlling a prompting lamp of the vehicle to adjust to a target angle, and controlling the prompting lamp to emit first prompting light according to the target angle so as to prompt a vehicle driving behind the vehicle to keep a vehicle distance.
For example, after the target angle is determined, the indicator light of the vehicle may be controlled to adjust to the target angle. Specifically, whether the warning light is adjusted to the target angle or not can be detected by an angle sensor arranged on the vehicle. Taking a vehicle running on a horizontal road as an example, when the indicator light is located in the horizontal direction, the angle detected by the angle sensor may be set to 0 °, and then when the angle of rotation of the indicator light from the horizontal direction to the direction perpendicular to the ground is consistent with the target angle, it may be determined that the indicator light has been adjusted to the target angle. Or when the prompting lamp is positioned in the direction vertical to the ground, the angle detected by the angle sensor is set to be 0 degrees, and then when the rotating angle of the prompting lamp from the direction vertical to the ground to the horizontal direction is consistent with the target angle, the prompting lamp can be determined to be adjusted to the target angle. When the warning light is adjusted to the target angle, the warning light can be continuously controlled, so that the warning light emits first warning light according to the target angle, and the first warning light can irradiate the ground behind the vehicle. The distance between the position of the first prompting light display on the ground behind the vehicle and the vehicle can be understood as the vehicle distance which can ensure the safe running of the vehicle and the vehicle behind. When a driver of the rear vehicle sees the first prompting light, the distance between the driver and the vehicle can be kept according to the prompt of the first prompting light, so that the problem that the vehicle is collided due to the fact that the distance is too small is solved. The rear vehicle and the vehicle run in the same direction, namely, the rear vehicle and the vehicle run in the same direction. The warning lamp may be disposed below the tail lamp of the vehicle, or may be disposed in the middle of two groups of tail lamps (i.e., the left and right tail lamps). The prompting lamp can be a laser lamp, a krypton lamp and the like, can be a group of laser lamps consisting of a plurality of laser lamps, and can be turned on or turned off by controlling the plurality of laser lamps in the group of laser lamps, so that the prompting lamp can display different characters or graphics on the ground.
When the target angle is an angle at which the warning light is turned from the horizontal direction to a direction perpendicular to the ground (i.e., the angle at which the warning light is positioned in the horizontal direction is 0 °), the vehicle distance that the rear vehicle needs to maintain is negatively correlated with the target angle, that is, the smaller the target angle, the larger the vehicle distance that the rear vehicle needs to maintain. When the target angle is an angle at which the warning light is turned from a direction perpendicular to the ground to a horizontal direction (that is, the angle at which the warning light is located in the direction perpendicular to the ground is 0 °), the distance that the rear vehicle needs to maintain is positively correlated with the target angle, that is, the larger the target angle is, the larger the distance that the rear vehicle needs to maintain is.
In summary, in the disclosure, the state data of the vehicle is first obtained, where the state data includes the driving speed of the vehicle, then the target angle is determined according to the driving speed, then the indicator light of the vehicle is controlled to adjust to the target angle, and the indicator light is controlled to emit the first indicator light according to the target angle, so as to indicate that the vehicle driving behind the vehicle maintains the inter-vehicle distance. The target angle of the prompting lamp is determined according to the state data, the prompting lamp is controlled to emit the prompting light according to the target angle, the target angle can be adjusted according to different state data, the first prompting light can be displayed at the corresponding distance, the distance between the vehicles at the rear is prompted to be kept, the problem that the vehicles collide due to the fact that the distance between the vehicles is too small is avoided, and the safety degree of vehicle driving is improved.
Fig. 2 is a flowchart illustrating another method for controlling a vehicle notification light according to an exemplary embodiment, where the status data further includes environmental information about a current driving of the vehicle, as shown in fig. 2, and the environmental information includes: at least one of weather information, road condition information and brightness information.
Step 102 comprises:
And step 1023, determining a target angle according to the initial angle and the adjustment angle.
For example, after the vehicle determines the target angle according to the driving speed, the first prompting light can be emitted according to the target angle, so that the rear vehicle can keep the distance between the vehicles. However, different environmental information may also affect the distance between the vehicle and the vehicle behind the vehicle. For example, rainy and snowy weather may cause the road surface on which the vehicle runs to be slippery, and the vehicle behind needs to increase the distance between the vehicle and the vehicle. Or rain, snow and foggy weather may cause the driver of the rear vehicle to have a blurred vision, so that the driver cannot observe the outline marker lamp of the vehicle, or even if the outline marker lamp is observed, the driver cannot accurately judge the vehicle distance, so that the driver cannot timely operate the rear vehicle, and the like. In a scene where a vehicle is running on an inclined road surface, the position on the ground surface of the warning light emitted by the warning light at a given angle is displayed differently from the position on the horizontal road surface irradiated with the warning light, and therefore, it is necessary to further determine the target angle in consideration of the inclination angle of the running road surface. That is, in determining the target angle, it is necessary to consider environmental information on the current running of the vehicle in addition to the running speed of the vehicle. Therefore, when the driving speed in the state data is obtained, the current driving environment information of the vehicle in the state data can also be obtained, wherein the environment information can include weather information, road condition information, brightness information and the like.
Specifically, the weather information may be determined by a humidity sensor, a rainfall sensor, or the like. If the humidity detected by the humidity sensor is greater than or equal to the preset humidity threshold value, which indicates that the humidity in the running environment of the vehicle is very high, the weather information can be determined as the rain, snow and fog weather. If the humidity detected by the humidity sensor is smaller than the preset humidity threshold value, which indicates that the humidity in the running environment of the vehicle is not high, the weather information can be determined to be clear weather. Or, if the rainfall detected by the rainfall sensor is greater than or equal to a preset rainfall threshold value, which indicates that the vehicle is raining in the driving environment, the weather information may be determined as the rainfall weather. If the rainfall detected by the rainfall sensor is smaller than the preset rainfall threshold value, which indicates that the vehicle does not rain in the driving environment, the weather information can be determined as clear weather. The road condition information can be determined by a vehicle event data recorder, a forward-looking camera and the like of the vehicle. For example, an image of a road where a vehicle is located may be acquired by a vehicle data recorder, and then the acquired image may be processed by an image processing model to determine whether a plurality of water accumulation portions exist in the acquired image. If the quantity of the collected water accumulation parts in the image exceeds the preset quantity, the road where the vehicle is located is slippery, and then the road condition information can be determined as a slippery road. If the quantity of the accumulated water in the collected image does not exceed the preset quantity, the road where the vehicle is located is dry, and then the road condition information can be determined as a dry road. Further, when determining the road condition information, the inclination angle of the vehicle can be measured by pressure sensors distributed at various positions of the vehicle body, angle measuring instruments arranged on the vehicle and the like, so as to determine the inclination angle of the running road surface of the vehicle. For example, if an acute angle between the direction from the front to the rear of the vehicle and the horizontal line is measured to be 20 °, which indicates that the vehicle is inclined upward and the inclination angle is 20 °, the road condition information may be determined to be 20 ° uphill. If the acute angle between the direction from the tail to the head of the vehicle and the horizontal line is measured to be 20 degrees, the vehicle inclines downwards and the inclination angle is 20 degrees, the road condition information can be determined as 20 degrees of downhill. The brightness information (e.g., strong light, normal light, weak light) can be determined by a photometric sensor provided on the vehicle.
After the state data is acquired, the specific implementation manner of determining the target angle according to the state data may be: the method comprises the steps of firstly inquiring a preset relation table A to determine an initial angle corresponding to the driving speed, and then determining an adjustment angle according to environmental information. When the adjustment angle is determined according to the environment information, for example, the relationship tables (e.g., relationship table B, relationship table C, and relationship table D) corresponding to the weather information, the road condition information, and the brightness information may be respectively queried to determine the adjustment angle corresponding to different environment information. For example, the corresponding relationship between the weather information and the adjustment angle of the indicator light may be stored in the preset relationship table B, the corresponding relationship between the road condition information and the adjustment angle of the indicator light may be stored in the preset relationship table C, the corresponding relationship between the brightness information and the adjustment angle of the indicator light may be stored in the preset relationship table D, and the adjustment angle may be determined according to the weather information, the road condition information, the brightness information, and the corresponding relationship tables. The adjustment angle may be the maximum value of adjustment angles corresponding to the weather information, the road condition information, and the brightness information, the minimum value of adjustment angles corresponding to the weather information, the road condition information, and the brightness information, or the average value of adjustment angles corresponding to the weather information, the road condition information, and the brightness information, and the like. In another implementation, if the environment information includes weather information and road condition information, but does not include brightness information, the adjustment angle may be determined according to the weather information, the road condition information, and a corresponding relationship table, which is not specifically limited in this disclosure. After the initial angle and the adjustment angle are determined, the target angle may be determined according to a preset functional relationship according to the initial angle and the adjustment angle, for example, the sum of the initial angle and the adjustment angle may be determined as the target angle, which is not limited by the present disclosure.
FIG. 3 is a flow chart illustrating another method of controlling a vehicle notification light, as shown in FIG. 3, prior to step 101, the method further comprising:
Step 101 comprises:
and if the first illumination intensity is smaller than a preset first light intensity threshold value, acquiring state data.
For example, when the vehicle travels on a road surface, the first illumination intensity of the current traveling environment of the vehicle may be detected in real time by a plurality of photometric sensors provided on the vehicle. The first illumination intensity may be an average value of illumination intensities detected by the plurality of photometric sensors, may also be a maximum value of illumination intensities detected by the plurality of photometric sensors, and may also be a minimum value of illumination intensities detected by the plurality of photometric sensors, which is not specifically limited in this disclosure. If the first illumination intensity is greater than or equal to the preset first light intensity threshold value, the visibility of the current running environment of the vehicle is high, the view of a driver of the vehicle behind is clear, and the driver can make a judgment in time when encountering an emergency (for example, the vehicle decelerates suddenly), so that the vehicle can prompt the driver of the vehicle behind without controlling the prompting lamp. If the first illumination intensity is smaller than the preset first light intensity threshold value, the visibility of the current running environment of the vehicle is low, the field of vision of a driver of the vehicle behind is fuzzy, and the driver is difficult to make a judgment in time when encountering an emergency, so that the vehicle can start to acquire state data, and the prompting lamp is controlled to emit first prompting light according to a target angle determined according to the state data so as to prompt the driver of the vehicle behind to keep the distance between the vehicles.
FIG. 4 is a flow chart illustrating another method of controlling a vehicle notification light, according to an exemplary embodiment, as shown in FIG. 4, the method further comprising:
and 105, acquiring a second illumination intensity behind the vehicle.
And 106, if the second illumination intensity is greater than a preset second light intensity threshold value, determining that the high beam of the rear vehicle is turned on.
And step 107, controlling the prompting lamp to emit second prompting light according to the target angle so as to prompt a rear vehicle to turn off the high beam.
For example, the second illumination intensity at the rear of the vehicle may be acquired by a photometric sensor disposed at the rear of the vehicle. If the second illumination intensity is greater than the preset second light intensity threshold value, it is indicated that the light behind the vehicle is dazzling, and the field of vision of the driver of the vehicle is affected, and then it can be determined that the rear vehicle turns on the high beam at the moment. Correspondingly, the vehicle can control the warning light to launch second warning light according to the target angle to the warning rear vehicle closes the high beam. If the second illumination intensity is smaller than or equal to the preset second light intensity threshold value, the fact that light behind the vehicle is soft is indicated, the view of a driver of the vehicle cannot be affected, then it can be determined that the high beam is not turned on by the vehicle behind, and at the moment, the prompting lamp can be continuously controlled to emit first prompting light according to the target angle, so that the vehicle behind is prompted to keep the distance between the vehicles. The second threshold may be the same as the first threshold or different from the first threshold (e.g., the second threshold is greater than the first threshold). The second prompting light may be a text prompting light (for example, "please turn off the high beam"), or an icon prompting light (for example, an icon corresponding to the high beam on the vehicle is crossed), which is not specifically limited in this disclosure. Further, a shield may be added to the photometric sensor disposed behind the vehicle to limit the range of light acquired by the photometric sensor. For example, the shading may be set at a preset angle (e.g., 45 °) at the upper edge and the lower edge of the luminosity sensor, respectively, so as to prevent the strong light in other directions from affecting the determination result of the vehicle.
FIG. 5 is a flow chart illustrating another method of controlling a vehicle notification light, according to an exemplary embodiment, where the status data further includes a steering status, and/or a safety status, as shown in FIG. 5. The method further comprises the following steps:
and step 108, if the steering state is left steering, controlling the prompting lamp to emit third prompting light according to the target angle.
And step 109, if the steering state is right steering, controlling the prompting lamp to emit fourth prompting light according to the target angle.
And step 110, if the safety state is abnormal, controlling the prompting lamp to emit fifth prompting light according to the target angle.
For example, the status data may further include a steering status, which may include a left turn, a right turn, a safety status, which may include a normal, an abnormal, etc. For example, the controller may acquire the states of a left turn indicator light, a right turn indicator light, and a hazard flasher light on the dashboard of the vehicle in real time. If the left turn indicator light is on, then the steering state may be determined to be left turn. If the right turn indicator light is on, then the steering state may be determined to be a right turn. If the hazard warning flash lights are on, the safety state can be determined to be abnormal. In another implementation, the controller may also make the determination of the steering status upon detection of a specified operation. For example, the controller may determine that the turning state is a left turn when detecting an operation of dialing the light lever down, and may determine that the turning state is a right turn when detecting an operation of dialing the light lever up. The controller may also acquire an operating state of each device (e.g., an engine, etc.) on the vehicle, and may determine that the safety state is abnormal if the number of devices whose operating states are abnormal exceeds a preset number (e.g., 3).
Specifically, if the steering state is left-turning, the indicator light can be controlled to emit third indicator light according to the target angle, and the third indicator light can be in a text form (for example, leftward) or an icon form (for example, an icon corresponding to left-turning on the vehicle). The driver of the rear vehicle can determine that the vehicle is about to turn left based on the third warning light. If the steering state is right-turning, the prompting lamp can be controlled to emit fourth prompting light according to the target angle, and the fourth prompting light can be in a text form (such as 'right') or an icon form (such as an icon corresponding to right-turning on the vehicle). The driver of the rear vehicle can determine that the vehicle is about to turn right based on the fourth cue light. If the safety state is abnormal, the prompting lamp can be controlled to emit fifth prompting light according to the target angle, and the fifth prompting light can be in a text form (for example, abnormal) or an icon form (for example, an icon corresponding to a danger alarm flash lamp on the vehicle). The driver of the rear vehicle can determine that the vehicle is abnormal according to the fifth warning light. Therefore, the driver of the rear vehicle can determine the state of the vehicle according to the prompt light emitted by the vehicle while keeping the distance, and timely make proper operation according to the state of the vehicle so as to ensure the driving safety of the rear vehicle and the vehicle.
In summary, in the disclosure, the state data of the vehicle is first obtained, where the state data includes the driving speed of the vehicle, then the target angle is determined according to the driving speed, then the indicator light of the vehicle is controlled to adjust to the target angle, and the indicator light is controlled to emit the first indicator light according to the target angle, so as to indicate that the vehicle driving behind the vehicle maintains the inter-vehicle distance. The target angle of the prompting lamp is determined according to the state data, the prompting lamp is controlled to emit the prompting light according to the target angle, the target angle can be adjusted according to different state data, the first prompting light can be displayed at the corresponding distance, the distance between the vehicles at the rear is prompted to be kept, the problem that the vehicles collide due to the fact that the distance between the vehicles is too small is avoided, and the safety degree of vehicle driving is improved.
