[0034] Embodiment 1

[0035] Figure 1 This is a schematic diagram of the structure 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 vehicle 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] The camera 110, the rain and fog weather detection device 120 and the controller 130, 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 the vehicle driving environment image; the rain and fog weather detection device 120 is used to detect the rain and fog weather status information, and the rain and fog weather status information is the information characterizing the severity of the 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 collect vehicle driving environment images and can be set above the vehicle cab or other locations. The vehicle driving environment images refer to images collected during the vehicle driving process, which can be environment images in the vehicle driving direction or other directions.

[0038] The rain and fog weather detection device 120 is used to detect the severity of rain and fog weather in the vehicle driving environment. For example, the rain and fog weather status information can be information such as air humidity or rainfall. The rain and fog weather detection device 120 can be composed of a rain detection device and a fog detection device, or it can be an integrated rain and fog weather detection device, which is not limited here.

[0039] The controller 130 is responsible for receiving the vehicle driving environment image and rainy and foggy weather status information, and processing the vehicle driving environment image through image recognition or a 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 vehicle driving environment image can be input into a pre-trained visibility distance detection model to obtain the visibility distance. The training steps of the visibility distance detection model include: obtaining multiple vehicle driving environment sample images and labels of each vehicle driving environment sample image, the labels including the real visibility distance; inputting the vehicle driving environment sample images into the neural network model to be trained, the neural network model outputs the predicted visibility distance, the model loss is calculated based on the predicted visibility distance and the real visibility distance, and then the neural network model parameters are updated based on the model loss until the model training stop condition is met to obtain the 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 turned on according to the visibility distance, and the vehicle speed can be adjusted according to the rain and fog weather status information. For example, when the visibility distance is less than 100 meters, the double flash lights are turned on; when the air humidity in the rain and fog weather status information is greater than 80% RH, the vehicle speed is adjusted to 30 kilometers per hour.

[0043] In some embodiments, the vehicle speed can also be adjusted according to the visibility distance, and the vehicle lights can be turned on according to the rainy and foggy weather status information. For example, when the visibility distance is less than 100 meters, the vehicle speed is adjusted to 50 kilometers per hour; when the rainfall in the rainy and foggy weather status information is greater than 15 mm, the double flash lights are turned on.

[0044] In some embodiments, the vehicle lights can be turned on and the vehicle speed can be adjusted according to the visibility distance and the rainy and foggy weather status information. For example, when the visibility distance is less than 100 meters and the rainfall in the rainy and foggy weather status information is greater than 15 mm, the hazard lights are turned on and the vehicle speed is adjusted to 40 kilometers per hour.

[0045] On the basis of the above-mentioned embodiments, optionally, the controller 130 is further used for: when the hazard lights are on, if the turn signal is on, then turning off the hazard lights; if the turn signal is off, then turning 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 be turned on and adjusts the vehicle speed through rainy and foggy weather status information and the vehicle driving environment image, thereby realizing adaptive control of the vehicle lights and speed in rainy and foggy weather, thereby improving the intelligence and safety of driving.

[0048] Embodiment 2

[0049] Figure 2 This is a structural schematic diagram of a vehicle control system provided in Embodiment 2 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 rainfall sensor 121 is used to collect the rainfall in the vehicle driving environment, which is used to measure the 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 fog in the vehicle driving environment.

[0051] Specifically, in foggy weather, the vehicle lights can be turned on and the vehicle speed can be adjusted according to the visibility distance and the humidity of the vehicle driving environment, realizing adaptive control of the vehicle lights and speed in foggy weather, thereby improving the intelligent degree and safety of driving. In rainy weather, the vehicle lights can be turned on and the vehicle speed can be adjusted according to the visibility distance and the rainfall in the vehicle driving environment, realizing adaptive control of the vehicle lights and speed in rainy weather, thereby improving the intelligent degree and safety of driving.

[0052] Optionally, the vehicle lights are controlled to be turned on and the vehicle speed is adjusted based on the visibility distance and the humidity of the vehicle's driving environment, including: when the humidity of the vehicle's 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's 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's 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, the position lights, the fog lights and the 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 driving speed > the second vehicle driving speed > the third vehicle driving speed. The first visibility distance range > the second visibility distance range > the third visibility distance range.

[0054] For example, Figure 3A : This is a schematic diagram of a foggy vehicle control strategy provided according to an embodiment of the present invention. The vehicle can be driven on a highway, expressway or other road. When the humidity of the vehicle driving environment is greater than the first preset humidity threshold value X1 and the visibility distance is less than 200 meters, the fog lights are automatically turned on, and at the same time, the controller controls the vehicle speed to not exceed 80 kilometers per hour through the vehicle speed sensor. When the humidity of the vehicle driving environment is greater than the second preset humidity threshold value X2 and the visibility distance is less than 100 meters, the fog lights and the double flash lights are automatically turned on, and at the same time, the controller controls the vehicle speed to not exceed 60 kilometers per hour through the vehicle speed sensor; when the turn signal is turned on when turning and changing lanes, the double flash lights are automatically turned off temporarily, and when the turn signal is turned off after turning and changing lanes, the double flash lights are automatically turned on. When the humidity of the vehicle driving environment is greater than the third preset humidity threshold value X3 and the visibility distance is less than 50 meters, the low beam headlights, clearance lights, fog lights and double flash lights are automatically turned on, and at the same time, the vehicle speed is controlled by the vehicle speed sensor 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 hazard 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 hazard 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 driving speed > the fifth vehicle driving speed > the sixth vehicle driving speed. The fourth visibility distance range > the fifth visibility distance range > the sixth visibility distance range.

[0057] For example, Figure 3B : This is a schematic diagram of a rainy day vehicle control strategy provided according to an embodiment of the present invention. The vehicle can be driven on a highway, expressway or other road. When the rainfall in the driving environment of the vehicle is greater than the first preset rainfall threshold value 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 through the vehicle speed sensor. When the rainfall in the driving environment of the vehicle is greater than the second preset rainfall threshold value Y2 and the visibility distance is less than 100 meters, the fog lights and double flash lights are automatically turned on, and the vehicle speed is controlled to not exceed 50 kilometers per hour through the vehicle speed sensor; when the turn signal is turned on when turning and changing lanes, the double flash lights are automatically turned off temporarily, and when the turn signal is turned off after turning and changing lanes, the double flash lights are automatically turned on. When the rainfall in the driving environment of the vehicle is greater than the third preset rainfall threshold value Y3 and the visibility is less than 50 meters, the low beam headlights, clearance lights, fog lights and double flash lights are automatically turned on, and the vehicle speed is controlled to not exceed 30 kilometers per hour through the vehicle speed sensor.

[0058] The technical solution of the embodiment of the present invention can control the vehicle lights to turn on and adjust the vehicle speed according to the visibility distance and the humidity of the vehicle driving environment in foggy weather, realizing adaptive control of the vehicle lights and speed in foggy weather, thereby improving the intelligent degree and safety of driving. In rainy weather, the vehicle lights can be controlled to turn on and adjust the vehicle speed according to the visibility distance and the rainfall in the vehicle driving environment, realizing adaptive control of the vehicle lights and speed in rainy weather, thereby improving the intelligent degree and safety of driving.

[0059] Embodiment 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 in the vehicle control system provided in the above 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; a controller 130, which is also used to inject rainwater and glass water concentrate into a mixing container based on a preset ratio when it is detected that the remaining amount of glass water is lower than a preset remaining amount threshold.

[0061] The rainwater collection device 140 includes but is not limited to a water inlet valve, a water storage container, and a filtering device, wherein the water inlet valve is electrically connected to the controller 130, and the water inlet valve is used to control whether rainwater collection is performed. In other words, when the water inlet valve is opened, rainwater can enter the water storage container. The water storage container is used to store rainwater. The filtering device is used to filter out impurities in rainwater. The preset residual threshold is a glass water residual threshold set based on experience, for example, the preset residual threshold can be 100ml, 200ml or other. The preset ratio is a mixing ratio of rainwater and glass water concentrate set based on experiments, for example, the preset ratio can be 10:1, 20:1 or other ratios.

[0062] For example, Figure 5 The present invention is a schematic diagram of a process of converting rainwater into glass water according to an embodiment of the present invention. Specifically, rainwater is collected by the rainwater collection device 140, and then the rainwater is filtered for impurities by the filtering device, and then the remaining amount of glass water is detected in real time by the liquid level sensor set in the glass water container. When it is detected that the remaining amount of glass water is less than 100 ml, the filtered rainwater and glass water concentrate are injected into the mixing container based on a ratio of 10:1, and then the mixed glass water in the mixing container is transported to the glass water container by the pump.

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

[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] Exemplarily, 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 6The present invention is a logical schematic diagram of converting rainwater into glass water provided in accordance with an embodiment of the present invention. The remaining amount of glass water is detected in real time by a liquid level sensor arranged in a glass water container. When the remaining amount of glass water is lower than a glass 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 condition, the water inlet valve is opened, that is, the rainwater collection function is activated to allow 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 condition or the remaining amount of glass water is not lower than the glass water remaining threshold, the water inlet valve is closed, that is, the rainwater collection function is closed.

[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, the driver can ensure that the windshield washer fluid tank is always in a suitable state without manual intervention. 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.
