[0034] Example 1

[0035] Figure 1 This is a structural diagram of a vehicle control system provided by the first embodiment of the present invention. This embodiment is applicable to the case of adaptive control of vehicle lights and speed in rainy and foggy weather. The vehicle control system can be implemented in the form of hardware and software, and the vehicle control system can be configured in a vehicle terminal. Figure 1 As shown, the vehicle control system includes:

[0036] A camera 110, a rain and fog weather detection device 120 and a controller 130, wherein the controller 130 is electrically connected to the camera 110 and the rain and fog weather detection device 120 respectively; the camera 110 is used to collect images of the vehicle driving environment; the rain and fog weather detection device 120 is used to detect rain and fog weather status information, wherein the rain and fog weather status information is information representing the severity of rain and fog weather; the controller 130 is used to determine the visibility distance based on the vehicle driving environment image, and control the vehicle lights to turn on and adjust the vehicle speed based on the visibility distance and the rain and fog weather status information.

[0037] The camera 110 is used to capture images of the vehicle's driving environment and can be located above the vehicle's cab or elsewhere. The vehicle's driving environment image refers to an image captured during the vehicle's driving process, which can be an image of the environment in the vehicle's driving direction or in other directions.

[0038] The rain and fog weather detection device 120 is used to detect the severity of rain and fog in the vehicle's driving environment. For example, the rain and fog weather status information may include information such as air humidity or rainfall. The rain and fog weather detection device 120 may be composed of a rain detection device and a fog detection device, or may be an integrated rain and fog weather detection device, without limitation herein.

[0039] The controller 130 is responsible for receiving the vehicle driving environment image and rain and fog weather status information, and processing the vehicle driving environment image through image recognition or neural network model to obtain the visibility distance. The visibility distance refers to the distance of air visibility. For example, the visibility distance can be 100m, 200m or other distances.

[0040] Specifically, the visibility distance can be obtained by inputting an image of the vehicle's driving environment into a pre-trained visibility distance detection model. The training steps of the visibility distance detection model include: obtaining multiple sample images of the vehicle's driving environment and labels for each sample image, including the true visibility distance; inputting the sample images of the vehicle's driving environment into a neural network model to be trained; the neural network model outputs a predicted visibility distance; calculating a model loss based on the predicted visibility distance and the true visibility distance; and then updating the neural network model parameters based on the model loss until the model training stop condition is met, thereby obtaining a visibility distance detection model.

[0041] Furthermore, the controller 130 can control the vehicle lights to turn on and adjust the vehicle speed according to the visibility distance and rainy and foggy weather status information.

[0042] In some embodiments, the vehicle lights can be controlled based on visibility distance, and the vehicle speed can be adjusted based on rainy or foggy weather conditions. For example, if the visibility distance is less than 100 meters, the hazard lights are activated; if the humidity in the rainy or foggy weather conditions is greater than 80%, the vehicle speed is adjusted to 30 kilometers per hour.

[0043] In some embodiments, the vehicle speed can be adjusted based on visibility distance, and the vehicle lights can be controlled based on rainy and foggy weather information. For example, if the visibility distance is less than 100 meters, the vehicle speed is adjusted to 50 kilometers per hour; if the rainfall in the rainy and foggy weather information is greater than 15 millimeters, the hazard lights are turned on.

[0044] In some embodiments, the vehicle lights can be activated and the vehicle speed can be adjusted based on the visibility distance and the rain and fog weather information. For example, if the visibility distance is less than 100 meters and the rainfall in the rain and fog weather information is greater than 15 mm, the hazard lights will be activated and the vehicle speed will be adjusted to 40 kilometers per hour.

[0045] On the basis of the above embodiments, optionally, the controller 130 is further configured to: when the hazard lights are on, if the turn signal is on, turn off the hazard lights; if the turn signal is off, turn on the hazard lights.

[0046] It should be noted that the purpose of the above setting is: when turning or changing lanes in rainy and foggy weather, the vehicle control system can temporarily turn off the hazard lights to allow the turn signals to work normally, and automatically restore the hazard lights after completion. The above design not only complies with traffic regulations, but also improves the smoothness and safety of driving in rainy and foggy weather.

[0047] The technical solution of the embodiment of the present invention comprehensively controls the vehicle lights to turn on and adjusts the vehicle speed through rainy and foggy weather status information and vehicle driving environment images, thereby realizing adaptive control of vehicle lights and speed in rainy and foggy weather, thereby improving the intelligence and safety of driving.

[0048] Example 2

[0049] Figure 2 This is a structural diagram of a vehicle control system provided in the second embodiment of the present invention. The system of this embodiment can be combined with the various optional schemes in the vehicle control system provided in the above embodiments. The vehicle control system provided in this embodiment has been further optimized. Optionally, the rain and fog weather detection device 120 includes a rain sensor 121 and a humidity sensor 122; the controller 130 is electrically connected to the rain sensor 121 and the humidity sensor 122 respectively; the humidity sensor 122 is used to collect the humidity of the vehicle driving environment; the rain sensor 121 is used to collect the rainfall in the vehicle driving environment; the controller 130 is specifically used to control the vehicle lights to turn on and adjust the vehicle speed based on the visibility distance and the vehicle driving environment humidity, or to control the vehicle lights to turn on and adjust the vehicle speed based on the visibility distance and the vehicle driving environment rainfall.

[0050] The rain sensor 121 is used to collect the amount of rainfall in the vehicle driving environment, which is used to measure the amount of rainfall in the vehicle driving environment. The humidity sensor 122 is used to collect the humidity in the vehicle driving environment, which is used to measure the amount of fog in the vehicle driving environment.

[0051] Specifically, in foggy weather, the vehicle lights can be controlled and the vehicle speed can be adjusted based on the visibility distance and the humidity of the vehicle's driving environment, achieving adaptive control of the vehicle lights and speed in foggy weather, thereby improving the intelligent and safer driving. In rainy weather, the vehicle lights can be controlled and the vehicle speed can be adjusted based on the visibility distance and the rainfall in the vehicle's driving environment, achieving adaptive control of the vehicle lights and speed in rainy weather, thereby improving the intelligent and safer driving.

[0052] Optionally, the vehicle lights are controlled to turn on and the vehicle speed is adjusted based on the visibility distance and the humidity of the vehicle driving environment, including: when the humidity of the vehicle driving environment is greater than the first preset humidity threshold and the visibility distance is within a first visibility distance range, turning on the fog lights and adjusting the vehicle speed to a first vehicle driving speed; when the humidity of the vehicle driving environment is greater than the second preset humidity threshold and the visibility distance is within a second visibility distance range, turning on the fog lights and the hazard lights and adjusting the vehicle speed to a second vehicle driving speed; when the humidity of the vehicle driving environment is greater than the third preset humidity threshold and the visibility distance is within a third visibility distance range, turning on the low beam lights, position lights, fog lights and hazard lights and adjusting the vehicle speed to a third vehicle driving speed.

[0053] The first preset humidity threshold < the second preset humidity threshold < the third preset humidity threshold. The first vehicle speed > the second vehicle speed > the third vehicle speed. The first visibility distance range > the second visibility distance range > the third visibility distance range.

[0054] For example, Figure 3A The figure is a schematic diagram of a vehicle control strategy for foggy conditions provided according to an embodiment of the present invention. The vehicle can be traveling on a highway, expressway, or other road. When the humidity in the driving environment exceeds a first preset humidity threshold X1 and the visibility distance is less than 200 meters, the fog lights are automatically activated. Simultaneously, a controller controls the vehicle's speed to not exceed 80 kilometers per hour, using a speed sensor. When the humidity in the driving environment exceeds a second preset humidity threshold X2 and the visibility distance is less than 100 meters, the fog lights and hazard lights are automatically activated. Simultaneously, a controller controls the vehicle's speed to not exceed 60 kilometers per hour, using a speed sensor. When a turn or lane change requires the turn signal to be activated, the hazard lights are temporarily deactivated. When the turn or lane change is complete and the turn signal is deactivated, the hazard lights are automatically activated. When the humidity in the driving environment exceeds a third preset humidity threshold X3 and the visibility distance is less than 50 meters, the low beam headlights, position lights, fog lights, and hazard lights are automatically activated. Simultaneously, a speed sensor controls the vehicle's speed to not exceed 40 kilometers per hour.

[0055] Optionally, the vehicle lights are controlled to be turned on and the vehicle speed is adjusted based on the visibility distance and the rainfall in the vehicle driving environment, including: when the rainfall in the vehicle driving environment is greater than the first preset rainfall threshold and the visibility distance is within a fourth visibility distance range, turning on the fog lights and adjusting the vehicle speed to a fourth vehicle driving speed; when the rainfall in the vehicle driving environment is greater than the second preset rainfall threshold and the visibility distance is within a fifth visibility distance range, turning on the fog lights and the double flash lights and adjusting the vehicle speed to a fifth vehicle driving speed; when the rainfall in the vehicle driving environment is greater than the third preset rainfall threshold and the visibility distance is within a sixth visibility distance range, turning on the low beam lights, the position lights, the fog lights and the double flash lights and adjusting the vehicle speed to a sixth vehicle driving speed.

[0056] The first preset rainfall threshold < the second preset rainfall threshold < the third preset rainfall threshold. The fourth vehicle speed > the fifth vehicle speed > the sixth vehicle speed. The fourth visibility distance range > the fifth visibility distance range > the sixth visibility distance range.

[0057] For example, Figure 3B The figure is a schematic diagram of a rainy day vehicle control strategy provided by an embodiment of the present invention. The vehicle can be traveling on a highway, expressway, or other road. When the rainfall in the driving environment exceeds a first preset rainfall threshold Y1 and the visibility distance is less than 200 meters, the fog lights are automatically turned on, and the vehicle speed is controlled to not exceed 70 kilometers per hour via a speed sensor. When the rainfall in the driving environment exceeds a second preset rainfall threshold Y2 and the visibility distance is less than 100 meters, the fog lights and hazard lights are automatically turned on, and the vehicle speed is controlled to not exceed 50 kilometers per hour via a speed sensor. When the turn signal is turned on to turn or change lanes, the hazard lights are temporarily turned off. When the turn signal is turned off after the turn or change is completed, the hazard lights are automatically turned on. When the rainfall in the driving environment exceeds a third preset rainfall threshold Y3 and the visibility is less than 50 meters, the low beam headlights, position lights, fog lights, and hazard lights are automatically turned on, and the vehicle speed is controlled to not exceed 30 kilometers per hour via a speed sensor.

[0058] The technical solution of the embodiments of the present invention can control the vehicle lights and adjust the vehicle speed in foggy weather based on the visibility distance and the humidity of the vehicle's driving environment, achieving adaptive control of vehicle lights and speed in foggy weather, thereby improving the intelligent and safe driving level. In rainy weather, the vehicle lights can be controlled and the vehicle speed can be adjusted based on the visibility distance and the rainfall in the vehicle's driving environment, achieving adaptive control of vehicle lights and speed in rainy weather, thereby improving the intelligent and safe driving level.

[0059] Example 3

[0060] Figure 4 This is a schematic diagram of the structure of a vehicle control system provided in the third embodiment of the present invention. The system of this embodiment can be combined with the various optional solutions of the vehicle control systems provided in the previous embodiments. The vehicle control system provided in this embodiment is further optimized. Optionally, the vehicle control system also includes: a rainwater collection device 140 for collecting and storing rainwater; and a controller 130 for injecting rainwater and windshield washer fluid concentrate into a mixing container based on a preset ratio when the remaining windshield washer fluid level is detected to be below a preset threshold.

[0061] The rainwater collection device 140 includes, but is not limited to, an inlet valve, a water storage container, and a filter. The inlet valve is electrically connected to the controller 130 and controls whether rainwater collection is enabled. In other words, when the inlet valve is open, rainwater can enter the water storage container. The water storage container stores rainwater. The filter removes impurities from the rainwater. The preset remaining threshold is an empirically determined windshield washer fluid remaining threshold, such as 100ml, 200ml, or other values. The preset ratio is an experimentally determined mixing ratio of rainwater to windshield washer fluid concentrate, such as 10:1, 20:1, or other ratios.

[0062] For example, Figure 5 The following is a schematic diagram of a process for converting rainwater into windshield washer fluid according to an embodiment of the present invention. Specifically, rainwater is collected by a rainwater collection device 140, then filtered for impurities by a filtration device. A liquid level sensor located in the windshield washer fluid container monitors the remaining windshield washer fluid level in real time. If the remaining windshield washer fluid level is less than 100 ml, filtered rainwater and windshield washer fluid concentrate are injected into a mixing container at a ratio of 10:1. The mixed windshield washer fluid in the mixing container is then pumped into the windshield washer fluid container via a pump.

[0063] On the basis of the above embodiments, optionally, the controller 130 is further configured to: open the water inlet valve to activate the rainwater collection function when the rainfall in the vehicle driving environment meets the rainwater collection conditions.

[0064] The rainwater collection condition may be that the rainfall in the vehicle driving environment is greater than 5 ml or other rainfall thresholds.

[0065] For example, when the rainfall in the vehicle driving environment is greater than 5 ml, the water inlet valve is opened to activate the rainwater collection function to allow rainwater to enter the water storage container.

[0066] Figure 6This is a logical schematic diagram of converting rainwater into windshield washer water provided according to an embodiment of the present invention. A liquid level sensor set in a windshield washer water container is used to detect the remaining windshield washer water in real time. When the remaining windshield washer water is lower than the windshield washer water remaining threshold, the rainfall detection in the vehicle driving environment is performed. When the rainfall in the vehicle driving environment meets the rainwater collection conditions, the water inlet valve is opened, that is, the rainwater collection function is activated, allowing rainwater to enter the water storage container, and the rainfall detection in the vehicle driving environment is continued. When the rainfall in the vehicle driving environment does not meet the rainwater collection conditions or the remaining windshield washer water is not lower than the windshield washer water remaining threshold, the water inlet valve is closed, that is, the rainwater collection function is turned off.

[0067] The technical solution of the embodiment of the present invention realizes the effective utilization of rainwater resources by automating the process of converting rainwater into windshield washer fluid. At the same time, it ensures that the windshield washer fluid tank is always in a suitable state without manual intervention by the driver. This convenience not only improves the user experience, but also reduces vehicle failures that may be caused by improper maintenance, bringing convenience to the driver.
