Exemplary method
Fig. 1 is a schematic flow chart of a vehicle control method provided in an embodiment of the present disclosure. The embodiment can be applied to an electronic device, as shown in fig. 1, and includes the following steps:
s1: and determining the relative position relation between the vehicle and the target tunnel portal based on the current position of the vehicle and the position of the target tunnel portal.
In the embodiment of the disclosure, the current position of the vehicle can be obtained according to the positioning result by positioning the vehicle. Specifically, the current position of the vehicle may be obtained by a Positioning device of the vehicle, for example, the vehicle is positioned by a Global Positioning System (GPS) or a beidou Positioning device, so as to obtain the current position of the vehicle. In addition, the vehicle can also be located by other terminals on the vehicle, for example, the locating device of the smart terminal such as a mobile phone locates the mobile phone, and the current position of the smart terminal such as the mobile phone is used as the current position of the vehicle.
In the embodiment of the present disclosure, the position of the target tunnel portal may be obtained by navigation software. For example, the navigation software stores information such as the tunnel entrance position, the tunnel length, and the tunnel name of the target tunnel entrance. When the vehicle starts navigation or the mobile terminal in the vehicle starts navigation, if the vehicle drives to and is close to the target tunnel entrance, the navigation software can provide the position information of the target tunnel entrance.
After the current position of the vehicle and the position of the target tunnel portal are acquired, the relative position relationship between the vehicle and the target tunnel portal can be determined based on the current position of the vehicle and the position of the target tunnel portal. The relative positional relationship between the vehicle and the target tunnel portal includes a distance between the vehicle and the target tunnel portal, and also includes a relationship between a traveling direction of the vehicle and the target tunnel portal. The relation between the driving direction of the vehicle and the target tunnel entrance comprises that the vehicle drives to the target tunnel entrance or the vehicle drives away from the target tunnel entrance.
S2: the ambient brightness of the vehicle is determined. The ambient brightness of the vehicle can be obtained through the sensor, or the ambient brightness of the vehicle can be determined in an image processing mode after image acquisition is carried out through the vehicle-mounted camera.
S3: and determining the target vehicle lamp needing to be adjusted on the vehicle based on the relative position relation between the vehicle and the target tunnel entrance and the ambient brightness of the vehicle. In the related specification, the low beam lamp is required to be turned on when the vehicle enters the tunnel, and therefore, the target vehicle lamp at least includes the low beam lamp of the vehicle. In addition, if the vehicle is started with other lamps before entering the tunnel, the other lamps need to be adjusted, that is, the target lamp may include other lamps which are originally in the operating state except for the dipped headlight.
S4: and adjusting the working state of the target vehicle lamp based on the ambient brightness. The working state of the target vehicle lamp can comprise turning on the target vehicle lamp, turning off the target vehicle lamp and adjusting the brightness of the target vehicle lamp.
In this embodiment, based on the ambient brightness of the vehicle and the distance between the vehicle and the target tunnel portal, the lights of the vehicle can be automatically controlled before the vehicle enters the tunnel and after the vehicle exits the tunnel, so that on one hand, the use requirements of relevant regulations on the lights of the vehicle can be met, on the other hand, the brightness change degree of the vehicle when the vehicle enters or exits the tunnel can be reduced through reasonable control of the lights, the visual adaptability of a driver when the driver enters or exits the tunnel is improved, and the probability of traffic accidents is reduced.
In one embodiment of the present disclosure, the target tunnel portal includes a tunnel entrance of the target tunnel, and the step S3 includes:
S3-A-1: and if the relative position relationship indicates that the vehicle is about to drive into the tunnel entrance, determining the size relationship between the ambient brightness and the preset ambient brightness threshold value.
In the embodiment of the present disclosure, if the relative position relationship indicates that the vehicle is about to enter the tunnel entrance, specifically, when the distance between the vehicle and the tunnel entrance is changed from being greater than a first preset distance to being less than or equal to the first preset distance, it is determined that the vehicle is about to enter the tunnel entrance. For example, the first preset distance may be 50 meters, that is, when the distance between the vehicle and the tunnel entrance is greater than 50 meters and is reduced to a distance of 50 meters or less, it is determined that the vehicle is about to enter the tunnel entrance.
And when the fact that the vehicle is about to enter the tunnel entrance is determined, comparing the magnitude relation between the environment brightness of the vehicle at the moment and a preset environment brightness threshold value. The preset environment brightness threshold value can be a preset brightness value with a fixed numerical value, and can also be a brightness value which is set according to whether the street lamp is started or not at the entrance of the tunnel. Based on the size relationship, a specific scenario for the vehicle to enter the tunnel entrance can be determined. If the ambient brightness of the vehicle is greater than a preset ambient brightness threshold value when the vehicle is about to enter the tunnel entrance, determining the vehicle is about to enter the tunnel in the daytime; and if the ambient brightness of the vehicle is less than or equal to the preset ambient brightness threshold value when the vehicle is about to enter the tunnel entrance, determining that the vehicle is about to enter the tunnel in the dark.
S3-A-2: and determining the target lamp needing to be adjusted on the vehicle based on the size relation.
In the disclosed embodiment, when it is determined that a scene is about to enter a tunnel during daytime, the target vehicle that needs to be adjusted includes a low beam. Thereafter, in step S4, adjusting the operating state of the target vehicle includes turning on the low beam (when the low beam is not turned on before the vehicle enters the tunnel), and may further include adjusting the brightness of the low beam according to the ambient brightness at the entrance of the tunnel.
When the situation that the vehicle is about to enter the tunnel in the dark day is determined, the target vehicle lights needing to be adjusted comprise low beam lights and high beam lights. Thereafter, in step S4, adjusting the operating state of the target vehicle includes turning on the low beam (when the low beam is not turned on before the vehicle enters the tunnel) and turning off the high beam (when the high beam is already turned on before the vehicle enters the tunnel), and may further include adjusting the brightness of the low beam according to the ambient brightness at the entrance of the tunnel.
Fig. 2 is a schematic diagram of a light control flow when a vehicle is about to enter a tunnel entrance in one example of the present disclosure. As shown in fig. 2, it is determined whether the vehicle is about to enter the tunnel entrance based on the position of the tunnel entrance and the current position of the vehicle, and it is determined that the vehicle is about to enter the tunnel entrance when, for example, the distance between the vehicle and the tunnel entrance changes from greater than 50 meters to 50 meters or less. When the fact that the vehicle is about to enter the tunnel entrance is determined, whether the environment brightness of the vehicle is larger than a preset environment brightness threshold value or not is detected. If the ambient brightness is larger than the preset ambient brightness threshold value, determining that the vehicle is about to enter the tunnel in the daytime, and turning on the dipped headlight at the moment; and if the ambient brightness is less than or equal to the preset ambient brightness threshold value, determining that the vehicle is about to enter the tunnel in the dark, and detecting whether the high beam of the vehicle is started. If the high beam is turned on at the moment, the dipped headlight needs to be turned on and the high beam needs to be turned off; if the high beam is in the off state in the scene of entering the tunnel in the dark, only the low beam needs to be turned on.
In the embodiment, when a vehicle is about to enter the tunnel, whether the vehicle is about to enter the tunnel in the daytime or in the dark is determined according to the ambient brightness of the vehicle, and the corresponding target vehicle lamp needing to be adjusted is selected based on the determined scene, so that the vehicle light can be automatically, quickly and accurately controlled, the probability of vehicle accidents is reduced, the safety of the vehicle entering the tunnel is improved, and the situation that the vehicle accidents are caused by the fact that the mistaken use of the light is not in accordance with the light use requirements in relevant regulations on one hand and the driver cannot adapt to the brightness at the entrance of the tunnel on the other hand is avoided.
In another embodiment of the present disclosure, the target tunnel portal includes a tunnel exit of the target tunnel, and the step S3 includes:
S3-B-1: and if the relative position relationship indicates that the vehicle reaches the tunnel exit, determining the size relationship between the ambient brightness and the preset ambient brightness threshold value.
In the embodiment of the present disclosure, if the relative position relationship indicates that the vehicle reaches the tunnel exit, specifically, when the distance between the vehicle and the tunnel exit is reduced from being greater than the second preset distance to being less than or equal to the second preset distance, it is determined that the vehicle reaches the tunnel exit. For example, the second preset distance may be 5 meters, that is, when the distance between the vehicle and the tunnel entrance is reduced from more than 5 meters to a distance of less than or equal to 5 meters, it is determined that the vehicle reaches the tunnel exit.
And when the vehicle reaches the exit of the tunnel, comparing the magnitude relation between the environment brightness of the vehicle at the moment and a preset brightness threshold value. The preset brightness threshold value may be a preset brightness value with a fixed numerical value, or a brightness value set according to whether the street lamp is turned on at the tunnel exit. Based on the size relationship, a specific scenario for the vehicle to reach the tunnel exit can be determined. If the ambient brightness of the vehicle is greater than a preset ambient brightness threshold value when the vehicle reaches the exit of the tunnel, determining that the vehicle is about to exit the tunnel in the daytime; and if the ambient brightness of the vehicle is less than or equal to the preset ambient brightness threshold when the vehicle reaches the exit of the tunnel, determining that the vehicle is about to exit the tunnel in the dark.
S3-B-2: and determining the target lamp needing to be adjusted on the vehicle based on the size relation.
In the disclosed embodiment, when it is determined that a scene is about to exit the tunnel during the daytime, the target vehicle that needs to be adjusted includes a low beam. Thereafter in step S4, adjusting the operating state of the target vehicle includes turning off the low beam.
When the situation that the vehicle is about to exit the tunnel in the dark day is determined, the target vehicle lights needing to be adjusted comprise low beam lights and high beam lights. Thereafter, in step S4, adjusting the operating state of the target vehicle includes keeping the low beam light on, or turning off the low beam light, and turning on the high beam light. Specifically, when the ambient brightness at the exit of the tunnel is greater than a preset high beam turn-on brightness threshold, turning on the low beam is kept; and when the ambient brightness at the exit of the tunnel is less than or equal to the given high beam opening brightness threshold and no other vehicle is in the vicinity of the vehicle within 100 meters, closing the dipped headlight and opening the high beam.
Fig. 3 is a schematic diagram of a light control flow path when a vehicle reaches a tunnel exit in one example of the present disclosure. As shown in fig. 3, it is determined whether the vehicle is about to enter or exit the tunnel exit based on the position of the tunnel exit and the current position of the vehicle, and it is determined that the vehicle is about to exit the tunnel exit when, for example, the distance between the vehicle and the tunnel exit changes from greater than 5 meters to 5 meters or less. When the vehicle is determined to be about to exit the tunnel exit, whether the ambient brightness of the vehicle is greater than a preset ambient brightness threshold value is detected. If the ambient brightness is larger than the preset ambient brightness threshold value, determining that the vehicle is about to exit from the tunnel in the daytime, and turning off the dipped headlight at the moment; if the environment brightness is smaller than or equal to the preset environment brightness threshold, determining that the vehicle is about to exit the tunnel in the dark, and detecting whether the high beam opening condition is met at the moment (for example, no vehicle exists in 100 meters nearby and the environment brightness is lower than the high beam opening brightness threshold). If the high beam light starting condition is not met, the dipped headlight works, namely the dipped headlight is kept in a starting state; if the high beam light starting condition is met, the high beam light works, namely the dipped headlight is turned off and the high beam light is turned on.
In this embodiment, when the vehicle reaches the tunnel exit, the scene that will be exited from the tunnel in daytime when the ambient brightness of the vehicle is determined, or the scene that will be exited from the tunnel in dark day, the corresponding target vehicle lamp that needs to be adjusted is selected based on the determined scene, so that the vehicle light can be automatically, quickly and accurately controlled, the probability of vehicle accidents is reduced, the safety when the vehicle enters the tunnel is improved, and the situation that the vehicle accidents occur due to the wrong use of the light is avoided, on one hand, the use requirement of the light in relevant regulations is not met, and on the other hand, the driver cannot adapt to the brightness at the entrance of the tunnel, which leads to the occurrence of the vehicle accidents.
In an embodiment of the present invention, after step S4, the method further includes: and controlling the vehicle to decelerate according to the inching brake mode, and/or performing deceleration prompt. The deceleration prompt mode comprises a voice mode, a mode of equipment vibration in the vehicle (such as seat vibration) or other modes for deceleration prompt.
In this embodiment, when the vehicle passes in and out of the tunnel, besides reasonable light control, the speed can be reduced in a snubbing mode, and speed reduction prompt is carried out, so that the probability of vehicle accidents at the entrance of the tunnel can be further reduced, and the safety of the vehicle passing in and out of the tunnel is improved.
In one embodiment of the present disclosure, step S2 includes: the environment brightness is determined through a brightness sensor arranged on the vehicle, or the environment brightness is determined after the shot vehicle environment image is subjected to image analysis. Wherein, confirm the ambient brightness through carrying out image analysis to the vehicle environment image of shooing, include: shooting an environment image of the vehicle through a camera of the vehicle; after the vehicle environment image is converted into a gray level image, acquiring the brightness values of all pixels in the gray level image; calculating the average brightness value of all pixels based on the brightness values of all pixels in the gray level image; the ambient brightness of the vehicle is determined based on the average brightness value of all the pixels and camera parameters including sensitivity, shutter time, and aperture size. The sensitivity affects the imaging quality, the lower the sensitivity brings finer imaging quality, and the higher the sensitivity the noise of the image quality is larger. The amount of light entering increases with longer shutter time, but the time is too long, and the picture is blurred by the shake. The larger the aperture is, the more the light input quantity is, the brighter the picture is, the narrower the focal plane is, and the larger the blurring of the main body background is; the smaller the aperture, the smaller the amount of light entering, the darker the screen, the wider the focal plane, and the sharper the front and back of the subject.
