[0056] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0057] The present application provides a method for controlling a water trough cover. The water trough cover 1 is arranged at the water trough of a vehicle. The water trough cover 1 is used to control the opening of the water trough. Figure 1 The control method of the water trough cover provided in the embodiment of the present application includes steps 100 to 200, which are described in detail below.

[0058] Step 100, identifying the vehicle body state and / or external environment, and obtaining the identification result.

[0059] Step 200, based on the recognition result, control the opening of the water trough cover 1 so that the water trough is closed or at least partially opened.

[0060] In the embodiment of the present application, through the above technical solution, the opening of the water trough cover 1 can be adjusted according to the recognized vehicle body state and / or external environment, so that the water trough is closed or at least partially opened, thereby meeting the needs of different application scenarios. For example, the opening of the water trough cover 1 is adjusted according to the driving state of the vehicle to adjust the wind resistance, or the opening of the water trough cover 1 is adjusted according to the temperature of the engine and / or drive motor in the vehicle to ensure the heat dissipation effect, or the opening of the water trough cover 1 is adjusted according to the amount of environmental rainfall to ensure that rainwater can be discharged from the vehicle.

[0061] The vehicle body state may include the driving state of the vehicle, the temperature of the engine and / or the drive motor in the vehicle, etc., and the external environment includes weather conditions, environmental rainfall and other conditions.

[0062] In some embodiments, according to the recognition result, controlling the opening of the water trough cover 1 so that the water trough is closed or at least partially opened includes:

[0063] When the vehicle is in a parking state, the water trough cover 1 is controlled to unfold so that the water trough is closed.

[0064] See also Figure 2 When the vehicle is in a parking state, the water channel cover 1 is controlled to be unfolded to close the water channel, thereby preventing foreign matter from entering the water channel and protecting the wiper 4 from being exposed to the sun.

[0065] In some embodiments, according to the recognition result, controlling the opening of the water trough cover 1 so that the water trough is closed or at least partially opened includes:

[0066] When the vehicle is in a constant speed driving state or an accelerated driving state and rain is not detected, the water trough cover 1 is controlled to be closed or partially unfolded so that the water trough is at least partially opened.

[0067] See also Figure 3 and Figure 4 When the vehicle is in a state of constant speed or accelerated driving and rain is not detected, the engine and / or drive motor in the vehicle are working, and the engine and / or drive motor will generate heat. The water flow channel cover 1 is closed or partially unfolded, and the water flow channel is at least partially opened, so that the outside air can enter the vehicle body from the water flow channel to assist the engine and / or drive motor in heat dissipation.

[0068] In some examples, controlling the water trough cover 1 to close or partially unfold so that the water trough is at least partially open includes:

[0069] When the temperature of the engine and / or the driving motor in the vehicle is greater than or equal to a preset temperature, the water flow channel cover 1 is controlled to be closed so that the water flow channels are fully opened.

[0070] See also Figure 3 When the temperature of the engine and / or drive motor in the vehicle is greater than or equal to the preset temperature, it means that the heat generated by the engine and / or drive motor is relatively large. At this time, the water flow channel cover 1 is controlled to be closed so that the water flow channels are fully opened, thereby increasing the amount of air entering the vehicle body and improving the heat dissipation effect of the engine and / or drive motor.

[0071] In other examples, controlling the water trough cover plate 1 to be closed or partially unfolded so that the water trough is at least partially opened further includes:

[0072] When the temperature of the engine and / or the driving motor in the vehicle is lower than a preset temperature, the water trough cover 1 is controlled to at least partially unfold, so that the water trough is at least partially opened.

[0073] See also Figure 4 When the temperature of the engine and / or the drive motor in the vehicle is lower than the preset temperature, it indicates that the heat generated by the engine and / or the drive motor is relatively low. At this time, the water flow channel cover 1 is controlled to be at least partially unfolded so that the water flow channel is at least partially opened, thereby ensuring the heat dissipation effect of the engine and / or the drive motor and reducing the wind resistance of the vehicle at the water flow channel.

[0074] In some examples, when the temperature of the engine and / or the drive motor in the vehicle is lower than a preset temperature, controlling the water trough cover 1 to at least partially unfold so that the water trough is at least partially opened includes:

[0075] When the temperature of the engine and / or the drive motor in the vehicle is lower than the preset temperature, the opening of the water trough cover 1 is controlled according to the following formula so that the water trough is at least partially opened:

[0076] K = (T0-T) / (T0-T e );

[0077] Wherein, K represents the opening degree of the water trough cover 1, T represents the temperature of the engine and / or the drive motor in the vehicle, T0 represents the preset temperature, T e Indicates the ambient temperature where the vehicle is located.

[0078] That is, according to the temperature T of the engine and / or the drive motor, the preset temperature T0 and the ambient temperature T e The opening of the water trough cover 1 is controlled according to the relationship between the two, so as to balance the heat dissipation effect of the engine and / or the driving motor in the vehicle and the wind resistance of the vehicle during driving.

[0079] It can be understood that K represents the opening of the water trough cover 1. When K=1, it means that the water trough cover 1 is fully unfolded, and the water trough is in a fully closed state. When K=0, it means that the water trough cover 1 is fully retracted, and the water trough is in a fully open state.

[0080] In some embodiments, according to the recognition result, controlling the opening of the water trough cover 1 so that the water trough is closed or at least partially opened includes:

[0081] When the vehicle is in a decelerating driving state and rain is not detected, the water trough cover 1 is controlled to be closed so that the water troughs are fully opened.

[0082] When the vehicle is decelerating and rain is not detected, the water trough cover 1 is controlled to be closed so that the water trough is fully opened, which can increase the wind resistance of the vehicle and assist the vehicle in decelerating.

[0083] See also Figure 3 and Figure 6 When the water trough cover 1 is closed, the water troughs are all opened, thereby enhancing the backflow vortex, increasing the wind resistance of the vehicle, and helping to assist the deceleration effect.

[0084] In some embodiments, according to the recognition result, controlling the opening of the water trough cover 1 so that the water trough is closed or at least partially opened includes:

[0085] When the vehicle is in a driving state and the ambient rainfall is less than the first preset rainfall, the water trough cover 1 is controlled to be unfolded so that the water trough is completely closed.

[0086] When the ambient rainfall is less than the first preset rainfall, the pollution degree of rainwater to the vehicle is low, and there is no need to turn on the wiper 4. The water trough cover 1 can be unfolded and the water trough remains in a completely closed state, which can reduce the wind resistance of the vehicle during driving.

[0087] See also Figure 2 and Figure 5 When the ambient rainfall is small, there is no need to start the wiper 4, and the water trough cover 1 can be unfolded, and the water trough remains closed, thereby reducing the backflow vortex formed at the water trough, thereby reducing the wind resistance of the vehicle during driving.

[0088] In some embodiments, according to the recognition result, controlling the opening of the water trough cover 1 so that the water trough is closed or at least partially opened includes:

[0089] When the vehicle is in a driving state and the ambient rainfall is greater than or equal to the first preset rainfall and less than the second preset rainfall, the water trough cover 1 is controlled to be partially unfolded so that the water trough is partially opened.

[0090] See also Figure 3 and Figure 4 When the ambient rainfall increases to a certain extent, the rain will pollute the front windshield 5 of the vehicle, and the rain needs to be discharged. Therefore, when the ambient rainfall is greater than or equal to the first preset rainfall and less than the second preset rainfall, the water channel cover 1 can be partially unfolded to partially open the water channel, which can balance the wind resistance and drainage effect of the vehicle during driving, and can facilitate the wiper 4 to wipe the front windshield 5, reducing the impact of rain on vision.

[0091] In some embodiments, according to the recognition result, controlling the opening of the water trough cover 1 so that the water trough is closed or at least partially opened includes:

[0092] When the vehicle is in a driving state and the ambient rainfall is greater than or equal to the second preset rainfall, the water trough cover 1 is controlled to be closed so that the water troughs are fully opened.

[0093] See also Figure 3 If the ambient rainfall continues to increase and is greater than or equal to the second preset rainfall, in order to allow the rainwater to be discharged in time and reduce the risk of rainwater entering the interior of the vehicle body, the water trough cover 1 is controlled to be closed so that the water troughs are fully opened.

[0094] In some examples, when the vehicle is in a driving state and the ambient rainfall is greater than or equal to the first preset rainfall and less than the second preset rainfall, the water trough cover 1 is controlled to be partially unfolded so that the water trough is partially opened, including:

[0095] When the vehicle is in a driving state and the rainfall is greater than or equal to the first preset rainfall and less than the second preset rainfall, the opening of the water trough cover 1 is controlled according to the following formula so that the water trough is partially opened:

[0096] K = MIN[(Q2-Q) / (Q2-Q1), 1];

[0097] Wherein, K represents the opening of the water channel cover 1, Q represents the ambient rainfall, Q1 represents the first preset rainfall, and Q2 represents the second preset rainfall.

[0098] That is, the opening of the water trough cover 1 is adjusted according to the relationship between the ambient rainfall Q, the first preset rainfall Q1 and the second preset rainfall Q2. Specifically, when the ambient rainfall is less than the second preset rainfall and greater than or equal to the first preset rainfall, the opening of the water trough cover 1 can be adjusted according to the ratio of the difference between the second preset rainfall and the ambient rainfall and the difference between the second preset rainfall and the first preset rainfall.

[0099] It can be understood that K represents the opening of the water trough cover 1. When K=1, it means that the water trough cover 1 is fully unfolded, and the water trough is in a fully closed state. When K=0, it means that the water trough cover 1 is fully retracted, and the water trough is in a fully open state.

[0100] In some embodiments, after controlling the opening of the water channel cover 1 according to the recognition result so that the water channel is closed or at least partially opened, the method further includes:

[0101] When the vehicle is in a driving state, the working state of the wiper 4 in the vehicle is controlled according to the ambient rainfall.

[0102] Specifically, when the ambient rainfall is less than or equal to the first preset rainfall, the wiper 4 can be kept in a closed state because the pollution degree of rainwater to the front windshield 5 is low. When the ambient rainfall is greater than or equal to the second preset rainfall, the wiper 4 can be turned on to the continuous operation (HI) gear to improve the wiping ability. When the ambient rainfall is greater than or equal to the first preset rainfall and less than the second preset rainfall, the wiper 4 can be turned on to the normal wiping gear or the low-speed continuous operation (L0) gear according to the ambient rainfall.
