Currently, vehicles frequently encounter water sprinkler trucks on the road. When a vehicle is ventilating with its windows open, encountering a water sprinkler truck usually has the following effects: the driver may hastily close the windows, which can distract them and potentially lead to driving safety issues; the driver may fail to close the windows in time, causing water to spray into the cabin, resulting in a poor driving experience. Summary of the Invention

Detailed Implementation

[0022] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] When a vehicle encounters a working water truck while driving, if the vehicle's windows are open, the driver's quick retraction of the windows will distract them. If the driver fails to retract the windows in time, water sprayed from the truck will enter the vehicle, resulting in a poor driving experience. Similarly, if there are sections of road with significant water accumulation, and the driver's quick retraction of the open windows will distract them, water splashing into the vehicle will enter if the driver fails to notice the water accumulation and retract the windows in time, also leading to a poor driving experience. Therefore, this application proposes a vehicle control method that can prevent water from entering the vehicle while reducing the likelihood of driver distraction, and improving vehicle safety and convenience.

[0024] The following description, with reference to the accompanying drawings, illustrates the vehicle control method, vehicle control device, and vehicle according to embodiments of the present invention.

[0025] Figure 1 This is a flowchart of a vehicle control method according to an embodiment of the present invention.

[0026] like Figure 1 As shown, the vehicle control method of this embodiment of the invention may include the following steps: S1: Obtain road environment information when it is determined that there is a risk of water ingress into the vehicle.

[0027] S2, controlling the vehicle windows and / or the vehicle's driving status based on road environment information, wherein the vehicle's driving status includes at least one of vehicle speed and driving route.

[0028] Specifically, if a vehicle's windows are open, there is a risk of water entering the vehicle under certain circumstances. For example, vehicles frequently encounter water trucks on the road. If a vehicle with its windows open for ventilation encounters a water truck and doesn't close the windows promptly, there is a risk of water entering the vehicle, especially if the vehicle is very close to the water truck. Similarly, when there is significant standing water on the road, if another vehicle is speeding past with its windows open for ventilation, there is a risk of water entering the vehicle. In cases where a risk of water entering the vehicle is confirmed, it is crucial to obtain road environment information, such as current road conditions, presence of vehicles behind, and the number of lanes on the road.

[0029] After acquiring road environment information, the system can control the vehicle windows accordingly. For example, if a vehicle is traveling in a two-lane road and encounters a water truck ahead, the windows can be automatically closed to prevent the driver from being distracted while hastily closing the windows, thus avoiding safety issues. Alternatively, the system can control the vehicle's driving status. For instance, if a vehicle is traveling in a single lane and encounters a flooded area ahead, the vehicle speed can be reduced due to uncertainty about the road conditions beneath the floodwaters. Or, if a vehicle is traveling in a two-lane road and encounters a flooded area, the speed can be increased to quickly change lanes. Alternatively, the system can control both the windows and the vehicle's driving status simultaneously. For example, if a vehicle is traveling in a three-lane road and encounters a water truck on the left front, the windows can be automatically closed, and the vehicle can be steered to another lane to accelerate and overtake.

[0030] Therefore, by obtaining road environment information when a vehicle is at risk of water ingress, and controlling the windows and / or the vehicle's driving status based on this information, it is possible to prevent water from entering the vehicle while reducing the likelihood of driver distraction and improving vehicle safety and convenience.

[0031] The specific workflow of the vehicle control method of the present invention is described in detail below.

[0032] According to one embodiment of the present invention, determining that a vehicle is at risk of water ingress includes: identifying that the water truck is in operation and the distance between the water truck and the vehicle is less than a preset distance threshold, thereby determining that the vehicle is at risk of water ingress. The preset distance threshold can be determined according to actual circumstances.

[0033] Specifically, if a driver opens the windows to ventilate the vehicle while it is in normal driving and encounters a working water truck in front of or to the left or right of the vehicle, there is a risk of water entering the vehicle. Therefore, if a risk of water ingress is identified, the first step is to determine if the water truck is currently operating. For example, a camera can be used to photograph the water truck and the image can be analyzed. If water spraying is detected, the water truck is confirmed to be operating; if no water spraying is detected, the water truck is confirmed to be not operating.

[0034] When the water truck is not in operation, there is no risk of water entering the vehicle regardless of the distance between the water truck and the vehicle. The risk of water entering the vehicle only exists when the water truck is in operation, such as when it is washing the road surface. If the distance between the water truck and the vehicle is too close, then the risk of water entering the vehicle can be determined. For example, the distance between the water truck and the vehicle can be determined by millimeter-wave radar. When the distance between the water truck and the vehicle is determined to be less than a preset distance threshold, it can be determined that the vehicle is at risk of water entering the vehicle.

[0035] It should be noted that the preset distance threshold can also be determined based on the relationship between the vehicle speed V1, the water truck speed V2, and the time it takes for the window to rise from the bottom to the top. For example, if the window takes 5 seconds to rise from the bottom to the top, and the water truck is approaching from the opposite direction, the current vehicle speed V1 can be defined as positive, the oncoming water truck speed V2 as negative, and V1 > V2, thus determining the preset distance as (V1 + V2). 5. When the water truck is traveling in the same direction as the current vehicle, the preset distance can be determined as (V1-V2). 5.

[0036] According to one embodiment of the present invention, road environment information includes lane information and the relative position of the sprinkler truck and the vehicle. Controlling the driving state of the vehicle windows and / or the vehicle based on the road environment information includes: determining that the lane information satisfies a change in driving route; when the relative position is forward, controlling the window to close, controlling the vehicle speed to increase to a first preset speed, and changing the driving route to move the vehicle away from the sprinkler truck; when the relative position is behind, controlling the vehicle speed to increase to a second preset speed, and controlling the window state and driving route to remain unchanged. The first and second preset speeds can be determined according to actual conditions.

[0037] Specifically, road environment information includes lane information and the relative position of the water truck and other vehicles. Lane information can include whether the current road is a single lane, two lanes, three lanes, or four or more lanes. The relative position of the water truck and other vehicles can vary, for example, the water truck may be to the left front, right front, left rear, right rear, directly in front, or directly behind the vehicle. When the lane is two lanes or three or more lanes, the lane information can be determined to allow the vehicle to change lanes, meaning the vehicle can move from its current lane to another lane. At this point, determine the relative position of the water truck and the vehicle. If the water truck is in front of the vehicle, for example, on a two-lane road, when the water truck is to the left front of the vehicle, the left window of the vehicle can be closed to prevent water from entering the vehicle through the left window. After closing the window, the vehicle speed can be increased, for example, to a first preset speed, and the driving route can be changed to overtake and move the vehicle away from the water truck. Similarly, if the water truck is to the right front of the vehicle, the right window of the vehicle can be closed to prevent water from entering the vehicle through the right window. After closing the window, the vehicle speed can be increased, for example, to a first preset speed, and the driving route can be changed to overtake and move the vehicle away from the water truck.

[0038] When the vehicle is positioned behind the water truck, for example, when the vehicle is traveling on a road with two or more lanes, the window can be kept in the same position if the water truck is behind the vehicle on the left or right. If the window was previously in the middle position when the vehicle encountered the water truck, the window will remain in the middle position. The vehicle speed will be increased to the second preset speed, and the current driving route will be maintained. The vehicle can continue to accelerate away from the water truck in the current lane.

[0039] According to one embodiment of the present invention, controlling the driving state of the vehicle window and / or the vehicle based on road environment information further includes: determining that the lane information does not meet the requirements for changing the driving route; when the relative position is forward, controlling the window to close and controlling the vehicle speed to remain unchanged or decrease to a third preset speed; when the relative position is backward, controlling the window state to remain unchanged and controlling the vehicle speed to increase to a fourth preset speed. The third and fourth preset speeds can be determined according to actual conditions.

[0040] Specifically, when lane information does not allow for changing the driving route, such as when a vehicle encounters a water truck in a one-way lane—meaning the vehicle cannot move away from the water truck by changing its route—the system first determines the relative position of the water truck and the vehicle. When the water truck is in front of the vehicle, the windows can be closed to prevent water sprayed from splashing into the windows when the vehicle is close. After closing the windows, the vehicle speed can be kept constant or reduced to a third preset speed to move away from the water truck. When the water truck is behind the vehicle, the windows can be kept in the same position, and the vehicle speed can be increased to a fourth preset speed to move the vehicle away from the water truck.

[0041] For example, when a vehicle is traveling on a two-lane road, and one lane is under construction, or there are many vehicles behind, making it impossible for the vehicle to change its route, the relative position of the water truck and the vehicle can be determined. When the water truck is in front of the vehicle, the windows can be closed to prevent water sprayed from splashing into the windows when the vehicle is too close. After closing the windows, the vehicle speed can be kept constant or reduced to a third preset speed to move away from the water truck. When the water truck is behind the vehicle, the windows can be kept in the same position, and the vehicle speed can be increased to a fourth preset speed to move away from the water truck. It should be noted that when encountering situations where it is impossible to move away from the water truck by changing the route on three or more lanes, the same method can be used to control the windows, or to control the windows and the vehicle's driving status.

[0042] Additionally, when approaching an intersection, such as on a designated straight road, with a red light ahead and a water truck in front of the vehicle, preventing the vehicle from changing lanes, overtaking, or accelerating away, the windows can be kept closed.

[0043] According to one embodiment of the present invention, determining that a vehicle is at risk of water ingress includes: determining that the vehicle is at risk of water ingress when the road surface is identified as being flooded.

[0044] Specifically, after a heavy rain or after the road has been sprayed with water, especially in areas with poor road conditions, the road surface is often uneven and flooded. If a vehicle drives through this flooded area with the windows open, water splashed up by the vehicle may enter the vehicle through the windows, resulting in a poor travel experience for the occupants. Therefore, when a camera identifies a flooded road surface, it indicates a risk of water entering the vehicle, and the windows should be closed.

[0045] According to one embodiment of the present invention, the road environment information includes the width of the floodwater and lane information. The driving state of the vehicle windows and / or the vehicle is controlled based on the road environment information, including: determining that the lane information meets the requirements for changing the driving route; when the width of the floodwater is greater than or equal to the lateral width of the vehicle, controlling the windows on both sides to close, controlling the vehicle speed to decrease to a fifth preset speed, and changing the driving route; when the width of the floodwater is less than the lateral width of the vehicle, controlling the state of the windows to remain unchanged or close, and changing the driving route to keep the vehicle away from the flooded road surface.

[0046] Specifically, road environment information may include the width of the floodwater and lane information. The width of the floodwater is determined by the width of the puddle, and lane information may include single-lane, two-lane, and multi-lane lanes. When the lane information allows for a change of route (i.e., when the vehicle can change lanes from its current lane to another), the width of the floodwater is compared with the lateral width of the vehicle. If the width of the floodwater is greater than or equal to the lateral width of the vehicle, for example, when the vehicle is traveling in a two-lane road and the floodwater is in front of it, the side windows of the vehicle can be closed, and the vehicle can be slowed down to a fifth preset speed to prevent excessive speed and large splashes of water from affecting other vehicles or pedestrians. Similarly, when the vehicle is traveling in a three-lane or more roadway and the floodwater is in front of it, the side windows of the vehicle can be closed, and the vehicle can be slowed down to a fifth preset speed to prevent excessive speed and large splashes of water from affecting other vehicles or pedestrians. The vehicle can also change its route from its current lane to an adjacent lane.

[0047] When the width of the floodwater is determined to be less than the lateral width of the vehicle, for example, when the vehicle is traveling in a two-lane road, if the flooded road surface is determined to be in front of the vehicle on the left, the left-side window of the vehicle can be closed, and the vehicle can be controlled to change lanes to the right to move the vehicle away from the flooded road surface. Similarly, if the flooded road surface is determined to be in front of the vehicle on the right, the right-side window of the vehicle can be closed, and the vehicle can be controlled to change lanes to the left to move the vehicle away from the flooded road surface. In this way, water splashed up when the vehicle passes through the flooded road surface can be prevented from entering the vehicle through the windows.

[0048] For example, when a vehicle is traveling on a road with three or more lanes, if it is determined that the flooded area is to the left front of the vehicle, the vehicle's windows can be kept unchanged, and the vehicle can be controlled to continuously change lanes to the right to move away from the flooded area. Similarly, if it is determined that the flooded area is to the right front of the vehicle, the vehicle's windows can be kept unchanged, and the vehicle can be controlled to continuously change lanes to the left to move away from the flooded area. This can prevent water splashed up when the vehicle passes through the flooded area from entering the vehicle through the windows.

[0049] It should be noted that before changing lanes, you need to check the rearview mirror to make sure there are no vehicles on the left or right rear side of the vehicle, or that there is safe space to change lanes, so as to avoid the roadside with water accumulation while driving safely.

[0050] According to one embodiment of the present invention, controlling the driving state of vehicle windows and / or vehicles based on road environment information includes: determining that lane information does not meet the requirements for changing the driving route; controlling the windows to close when the width of the water accumulation is greater than or equal to the lateral width of the vehicle; and controlling the windows to close when the width of the water accumulation is less than the lateral width of the vehicle, so as to keep the vehicle away from the waterlogged road surface.

[0051] Specifically, when lane information does not allow for changing the driving route, such as when the vehicle is currently traveling in a single lane and encounters a flooded area, the width of the floodwater is compared to the vehicle's lateral width. If the width of the floodwater is greater than or equal to the vehicle's lateral width, it indicates that the flood area is large and the vehicle cannot avoid it. In this case, the windows can be closed to prevent splashing water from entering the vehicle, and the vehicle should be slowly driven through the flooded area. If the width of the floodwater is less than the vehicle's lateral width, it indicates that the flood area is small. In this case, the windows can be closed to prevent splashing water from entering the vehicle, and the vehicle can be moved away from the flooded area to avoid driving the entire vehicle into the flooded area.

[0052] For example, if a vehicle is traveling in a two-lane road, one of which is under construction, or if there are many vehicles behind, making it impossible to change lanes, and encounters a flooded area, compare the width of the floodwater with the vehicle's lateral width. If the width of the floodwater is greater than or equal to the vehicle's lateral width, the flood area is large and the vehicle cannot avoid it. In this case, close the windows to prevent water from splashing into the vehicle and slowly move the vehicle through the flooded area. If the width of the floodwater is less than the vehicle's lateral width, the flood area is small. In this case, close the windows to prevent water from splashing into the vehicle and move the vehicle away from the flooded area to avoid driving the entire vehicle into the flooded area. It should be noted that when encountering flooded areas with three or more lanes where changing lanes is not an option, the same method can be used to control the windows, or to control the windows and the vehicle's movement.

[0053] According to one embodiment of the present invention, when it is determined that there is no risk of water ingress into the vehicle, the windows are controlled to return to their previous state.

[0054] Specifically, if it is determined that there is no risk of water ingress into the vehicle, the windows can be controlled to return to their previous state. For example, before the vehicle encounters a working water truck, when the distance between the two trucks is relatively far, the vehicle windows are half-open for ventilation. As the vehicle gets closer to the water truck until it is less than a preset distance threshold, the corresponding windows are controlled to close. After the vehicle drives away from the water truck, when the distance between the two trucks again exceeds the preset distance threshold, the windows can be controlled to return to their previous state, i.e., return to the half-open state.

[0055] For example, before encountering a flooded road, the vehicle's windows are half-open for ventilation. When encountering floodwater, the windows are closed. After driving for a while, once a camera confirms there is no more water ahead, the windows can be returned to their previous half-open position. Furthermore, if the vehicle's route changes while the windows are being returned to their previous position, the vehicle can be controlled to resume its original route.

[0056] In summary, by combining road environment information to perform lane changing, acceleration / deceleration to avoid obstacles, and window closing for waterproofing, after successfully avoiding a water truck or a flooded road, the vehicle can resume its original driving route and restore the windows to their pre-avoidance state without driver intervention.

[0057] In summary, the vehicle control method according to embodiments of the present invention, when determining that there is a risk of water ingress into the vehicle, acquires road environment information and controls the vehicle windows and / or the vehicle's driving state based on the road environment information. The vehicle's driving state includes at least one of vehicle speed and driving route. Therefore, this method can prevent water from entering the vehicle while reducing the probability of driver distraction, and improve the safety and convenience of vehicle operation.

[0058] Corresponding to the above embodiments, the present invention also proposes a vehicle control device.

[0059] like Figure 2 As shown, the vehicle control device 100 of this embodiment includes: an acquisition module 110 and a control module 120.

[0060] The acquisition module 110 is used to acquire road environment information when it is determined that there is a risk of water ingress into the vehicle. The control module 120 is used to control the windows and / or the driving status of the vehicle based on the road environment information, wherein the driving status of the vehicle includes at least one of vehicle speed and driving route.

[0061] According to one embodiment of the present invention, the acquisition module 110 determines that the vehicle is at risk of water ingress, specifically for: identifying that the water truck is in operation and the distance between the water truck and the vehicle is less than a preset distance threshold, and then determining that the vehicle is at risk of water ingress.

[0062] According to one embodiment of the present invention, the road environment information includes lane information and the relative position of the sprinkler truck and the vehicle. The control module 120 controls the driving state of the windows and / or the vehicle based on the road environment information, specifically for: determining that the lane information meets the requirements for changing the driving route; when the relative position is forward, controlling the windows to close, controlling the vehicle speed to increase to a first preset speed, and changing the driving route to move the vehicle away from the sprinkler truck; when the relative position is behind, controlling the vehicle speed to increase to a second preset speed, and controlling the state of the windows and the driving route to remain unchanged.

[0063] According to one embodiment of the present invention, the control module 120 controls the driving state of the windows and / or the vehicle based on road environment information, and is further configured to: determine that the lane information does not meet the requirements for changing the driving route; when the relative position is forward, control the windows to close and control the vehicle speed to remain unchanged or decrease to a third preset speed; when the relative position is backward, control the windows to remain unchanged and control the vehicle speed to increase to a fourth preset speed.

[0065] According to one embodiment of the present invention, the road environment information includes the width of the floodwater and lane information.

[0066] According to one embodiment of the present invention, the control module 120 controls the driving status of the windows and / or the vehicle based on road environment information, specifically for: determining that the lane information does not meet the requirements for changing the driving route; controlling the windows to close when the width of the water accumulation is greater than or equal to the lateral width of the vehicle; and controlling the windows to close when the width of the water accumulation is less than the lateral width of the vehicle, so as to keep the vehicle away from the waterlogged road surface.

[0067] According to one embodiment of the present invention, the control module 120 is further configured to: control the windows to return to their previous state if it is determined that there is no risk of water ingress into the vehicle.
