In step 403, the server detects whether the distance between the real-time location and the target location in the navigation route of the vehicle is less than a distance threshold and whether the real-time brightness is greater than a first brightness threshold.
The ambient brightness of the target position is smaller than the second brightness threshold value, and the second brightness threshold value is smaller than the first brightness threshold value. The distance threshold, the first brightness threshold and the second brightness threshold are all fixed values stored in the server in advance. For example, the distance threshold may be 5 meters, and the first brightness threshold may be a brightness value determined according to the brightness of the daytime ambient light, for example, the first brightness threshold may be 10000 nit (nit). The target location may be the location where a tunnel or bridge opening is located.
After receiving the real-time position and the real-time brightness sent by the vehicle, the server may detect whether a distance between the real-time position and a target position located in a navigation route of the vehicle is less than a distance threshold and whether the real-time brightness is greater than a first brightness threshold. If the distance between the real-time location and the target location is less than the distance threshold and the real-time brightness is greater than the first brightness threshold, it may be determined that the vehicle will enter the darker environment from the lighter environment, and step 404 may be performed.
If the distance between the real-time position and the target position is not less than the distance threshold value, and the real-time brightness is greater than a first brightness threshold value. Or the distance between the real-time position and the target position is smaller than a distance threshold, and the real-time brightness is not larger than a first brightness threshold.

After receiving the real-time location sent by the vehicle, the server may determine, from the electronic map, one or more target locations in the navigation route of the vehicle where the ambient brightness is less than a second brightness threshold. The server can then detect whether the real-time location of the vehicle is within the electronic fence of any of the target locations. If the electronic fence is located at a target position, it can be determined that the distance between the real-time position and the target position is less than the distance threshold.
Optionally, the server may generate one or more navigation routes upon receiving the destination sent by the vehicle, and may then send the one or more navigation routes to the vehicle. The vehicle may display the one or more navigation routes via the display screen after receiving the one or more navigation routes. After receiving a selection instruction of any navigation route from the user, the vehicle can send the navigation route selected by the user to the server. The server may determine the target location based on the navigation route sent by the vehicle.
The server determines the weather at the real-time location and the local time, step 404.
The server may determine weather and local time at the real-time location after determining that the distance between the real-time location and the target location is less than a distance threshold and the real-time brightness is greater than the first brightness threshold.
Alternatively, the server may send the real-time location to a third party platform and receive the weather at the real-time location and the local time at the real-time location returned by the third party platform.
Step 405, the server detects whether the local time is within the target time range and whether the weather is the target weather.
The server may have a target time range and a target weather stored therein in advance. After determining the weather at the real-time location and the local time, the server may detect whether the local time is within the target time range and whether the weather is the target weather, respectively. If the local time is within the target time range and the weather is the target weather, step 406 may be executed. If the local time is not within the target time range, and the weather is the target weather. Or the local time is within the target time range and the weather is not the target weather. Or the local time is not within the target time range and the weather is not the target weather, the process may be ended.
For example, the target time range may be a time range of day, such as 9 am to 5 pm. The target weather may be clear.
Step 406, the server sends a prompt to the vehicle.
The server can send prompt information to the vehicle after determining that the distance between the real-time position and the target position is smaller than a distance threshold value, the real-time brightness is larger than the first brightness threshold value, the local time is within a target time range, and the weather is target weather, wherein the prompt information is used for prompting a driver that the vehicle will reach the target position. The reliability of determining whether the vehicle is driven from a brighter environment to a darker environment is improved due to the consideration of multiple factors.

In the embodiment of the disclosure, after the vehicle displays the prompt message, the vehicle lamp can be controlled to be turned on in response to the confirmation instruction aiming at the prompt message, so that the driver can know the front road condition information in advance before the vehicle enters the darker environment from the brighter environment. Illustratively, the vehicle light may be a headlamp external to the vehicle.
Optionally, if the vehicle plays the prompt message in voice, after receiving a voice confirmation instruction triggered by the driver, the vehicle may confirm that a confirmation instruction for the prompt message is received, and then may control the vehicle light to turn on in response to the confirmation instruction.
For example, the vehicle may play the prompt message "enter a tunnel ahead and please start the tunnel mode", after receiving a voice confirmation instruction triggered by the driver, the vehicle may confirm that the confirmation instruction for the prompt message is received, and may control the vehicle lights to turn on in response to the confirmation instruction. The voice confirmation instruction may be voice "on" or voice "confirm".
Optionally, if the vehicle displays the prompt message on the display screen, a confirmation button and a cancel button may also be displayed on the display screen. After detecting the selection instruction for the confirmation button, the vehicle may confirm that the confirmation instruction for the prompt message is received, and may further control the lamps to be turned on in response to the confirmation instruction.
For example, the vehicle may display "enter tunnel ahead, please turn on tunnel mode", a confirm button, and a cancel button on the display screen. After detecting the selection instruction for the confirmation button, the vehicle may confirm that the confirmation instruction for the prompt message is received, and may further control the lamps to be turned on in response to the confirmation instruction.
Alternatively, the vehicle may automatically control the lights to turn on. Or, the vehicle is provided with a lamp starting button, and the vehicle can control the lamp to be turned on after detecting a selection instruction of the lamp starting button.
And step 409, responding to the confirmation instruction aiming at the prompt message, and opening the camera.
In the disclosed embodiment, the exterior of the vehicle is provided with a camera. If the vehicle plays the prompt message by voice, the vehicle can confirm that the confirmation command aiming at the prompt message is received after receiving the voice confirmation command triggered by the driver, and then can respond to the confirmation command and open the camera.
For example, the vehicle may play the prompt message "the vehicle is about to enter the tunnel ahead and please start the tunnel mode", after receiving the voice confirmation instruction triggered by the driver, the vehicle may confirm that the confirmation instruction for the prompt message is received, and then may open the camera in response to the confirmation instruction. The voice confirmation instruction may be voice "on" or voice "confirm".
If the vehicle displays the prompt message on the display screen, a confirmation button and a cancel button can also be displayed on the display screen. After detecting the selection instruction for the confirmation button, the vehicle can confirm that the confirmation instruction for the prompt message is received, and then can open the camera in response to the confirmation instruction.
For example, the vehicle may display "enter tunnel ahead, please turn on tunnel mode", a confirm button, and a cancel button on the display screen. After detecting the selection instruction for the confirmation button, the vehicle can confirm that the confirmation instruction for the prompt message is received, and then can open the camera in response to the confirmation instruction.
It should be noted that, after the vehicle displays the prompt message, the vehicle may control the vehicle light to turn on and turn on the camera at the same time in response to the confirmation instruction for the prompt message.
Alternatively, the vehicle may automatically turn on the camera. Or the vehicle can be provided with a camera opening button, and the camera is opened after a selection instruction of the driver for the camera opening button is detected.
Optionally, an augmented reality head up display (AR HUD) system may be installed in the vehicle, and the vehicle may open the AR HUD system while opening the camera.
And step 410, shooting the front road condition information of the vehicle through a camera.
