Description

Technical Field

[0001] This application relates to the technical field of vehicle control, and particularly to a vehicle waterproofing method, device, system, storage medium, and vehicle. Background Art

[0002] If components such as the engine, electrical system, air filter, air intake, brake system, and exhaust pipe of a vehicle are flooded, the functions of these components themselves cannot be realized, or it will have a greater impact on the performance of the vehicle. Therefore, these components are greatly affected by flooding, and a vehicle being flooded essentially means these components are flooded.

[0003] In the prior art, when the vehicle is in the locked state, when rainfall or other reasons cause water accumulation on the road surface, if the vehicle is in a low-lying area, the above-mentioned components may be at risk of being flooded, thus causing losses to the vehicle owner. Therefore, how to provide a vehicle waterproofing method to reduce the risk of the vehicle being flooded has become an urgent technical problem to be solved. Summary of the Invention

[0004] This application provides a vehicle waterproofing method, device, system, storage medium, and vehicle to reduce the risk of the vehicle being flooded.

[0005] This application provides a vehicle waterproofing method, including:

[0006] Determine the water level alarm threshold related to the vehicle height information by querying the correspondence table between vehicle height information and the water level alarm threshold;

[0007] Obtain the water level in a preset area below the vehicle;

[0008] When the water level in the preset area below the vehicle reaches the water level alarm threshold, determine whether the vehicle is equipped with an air suspension system;

[0009] When the vehicle is equipped with an air suspension system and the suspension height of the air suspension system has not reached the maximum suspension height, control the vehicle to raise the suspension height of the air suspension system.

[0010] The beneficial effect of the present application is that when the water level in the preset area below the vehicle reaches the water level alarm threshold, and the vehicle can raise the suspension height of the air suspension system, the vehicle is controlled to raise the suspension height of the air suspension system to increase the height of the vehicle chassis. Since raising the chassis height is equivalent to raising the height of the components that are greatly affected by flooding, the risk of the components on the vehicle being flooded is reduced. In addition, since there is an upper limit to the water level increase, even if the water level rises, there is a maximum water level height. Therefore, the greater the height of the components that are greatly affected by flooding, the more likely it is to be greater than the maximum water level height, thereby reducing the risk of the vehicle being flooded; in addition, even if the height of the components that are greatly affected by flooding after the height is raised is still less than the maximum water level height, raising the height of these components can also delay the time when these components are flooded, buy more time for the owner to move the vehicle independently, and can also reduce the risk of the vehicle being flooded.

[0055] The drawings are used to provide a further understanding of this application, and constitute a part of the specification. Together with the embodiments of this application, they are used to explain this application and do not constitute a limitation to this application. In the drawings:

[0059] The following describes the preferred embodiments of this application with reference to the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain this application, and are not used to limit this application.

[0060] Figure 1 is a flowchart of a vehicle waterproofing method in an embodiment of this application. As Figure 1 shown, the method can be implemented as the following steps S101 - S104:

[0061] In step S101, determine the water level alarm threshold related to the vehicle height information by querying the correspondence table of vehicle height information and water level alarm threshold;

[0062] In step S102, obtain the water level in the preset area under the vehicle;

[0063] In step S103, when the water level in the preset area under the vehicle reaches the water level alarm threshold, determine whether the vehicle is equipped with an air suspension system;

[0064] In step S104, when the vehicle is equipped with an air suspension system and the suspension height of the air suspension system does not reach the maximum suspension height, control the vehicle to raise the suspension height of the air suspension system.

[0065] Determine the water level alarm threshold related to the vehicle height information by querying the correspondence table of vehicle height information and water level alarm threshold. In the prior art, when it rains or there is water accumulation on the road surface for other reasons, if the vehicle is in a low-lying area, there may be a risk that some components of the vehicle are flooded, thus causing losses to the vehicle owner. To determine whether there is a risk of the vehicle being flooded, this application determines the water level alarm threshold of the vehicle at the current moment by querying the preset correspondence table of vehicle height information and water level alarm threshold. Among them, the water level alarm threshold can be a preset fixed value; and since the angle information between the vehicle and the ground and the height of the air suspension system will both cause the relative positions of the vehicle and the water level under the vehicle to be different, therefore, the water level alarm threshold can also be dynamically adjusted. In an embodiment of this application, first, obtain the angle information between the vehicle and the ground and the height information of the vehicle's air suspension system. Specifically, the angle information between the vehicle and the ground and the height information of the air suspension system can be directly obtained through the body controller, or the vehicle environment information can be collected through a camera, and the angle information between the vehicle and the ground and the height information of the air suspension system can be determined through image recognition. Then, query the correspondence table of vehicle height information and water level alarm threshold according to the angle information between the vehicle and the ground and the height information of the vehicle's air suspension system to determine the water level alarm threshold corresponding to the current vehicle height information. Among them, the correspondence table of vehicle height information and water level alarm threshold includes the correspondence between the angle information between the vehicle and the ground and the height information of the vehicle's air suspension system and the vehicle water level alarm threshold.

[0066] While obtaining the water level alarm threshold of the current vehicle, the water level in a preset area below the vehicle is obtained. To determine the water level below the vehicle, a laser level gauge can be used to judge the water level below the vehicle. For example, four laser level gauges are set at four positions of the left front, right front, left rear, and right rear of the vehicle chassis, and then the body controller controls the laser level gauges to periodically obtain the liquid level below the vehicle, and determines whether the maximum detection value among the detection values of the four laser level gauges exceeds the water level alarm threshold. When the maximum detection value exceeds the water level alarm threshold, it is determined that the water level in the area where the laser level gauge corresponding to the maximum detection value is located has reached the water level alarm threshold. Another example is that the number of preset laser level gauges with a relatively low absolute height from the ground can be determined according to the angle information between the vehicle and the ground, and the corresponding laser level gauges are turned on to periodically obtain the liquid level below the vehicle, and the detection value of the laser level gauge is compared with the water level alarm threshold. When the water level alarm threshold is reached, it is determined that the water level in the area where the turned-on laser level gauge is located has reached the water level alarm threshold. Another example is that when the water levels detected by the four laser level gauges exceed a preset threshold for two or more, it can also be determined that the water level in the preset area below the vehicle has reached the water level alarm threshold. Of course, the corresponding water level height can also be determined according to the image of the area below the vehicle collected by the camera; the number of cameras and level gauges can be increased or decreased according to the actual vehicle situation. In addition, for the frequency of water level acquisition, it can be adjusted according to the water level situation under the vehicle. If it is detected that the water level does not reach the preset threshold, the detection period is reduced. For example, data is collected at a period of 1 minute during the sleep period; if it is detected that the water level reaches the preset threshold, data can be collected at a period of 1 second.

[0067] When the water level in the preset area below the vehicle reaches the water level alarm threshold, it is judged whether the vehicle is equipped with an air suspension system. To determine whether the height of the air suspension system of the current vehicle can be increased, first, it is judged whether the vehicle is equipped with an air suspension system. Since whether different vehicle models are equipped with an air suspension system is predetermined, it is possible to determine whether the vehicle is equipped with an air suspension system according to the vehicle model of the current vehicle. When the vehicle is equipped with an air suspension system, the suspension height of the air suspension system is obtained. Specifically, it can be obtained by querying through the vehicle's on-board information system. When the suspension height of the air suspension system reaches the maximum suspension height, it is determined that the height of the vehicle's air suspension system cannot be increased; when the suspension height of the air suspension system does not reach the maximum suspension height, it is determined that the height of the vehicle's air suspension system can be increased. In addition, when the vehicle is not equipped with an air suspension system, it is determined that the vehicle cannot increase the suspension height of the air suspension system.

[0068] When the vehicle is capable of raising the suspension height of the air suspension system, control the vehicle to raise the suspension height of the air suspension system. That is, when the vehicle is equipped with an air suspension system and the suspension height of the air suspension system has not reached the maximum suspension height, by waking up the body controller, control the air suspension system to raise. For example, the height of the air suspension system can be raised to the highest, and then the chassis height of the vehicle can be raised to the highest to reduce the risk of some components of the vehicle being flooded.

[0069] Furthermore, to prevent the vehicle from being flooded, after controlling the vehicle to raise the suspension height of the air suspension system, or in the case where the vehicle cannot raise the suspension height of the air suspension system, such as when the vehicle is not equipped with an air suspension, or the suspension height of the air suspension system of the vehicle has reached the maximum suspension height, send an alarm prompt to the user terminal to remind the user to move the vehicle. In addition, after sending the alarm prompt, it can also be monitored whether the user moves the vehicle within a preset time. When the user does not move the vehicle, control the vehicle to automatically move the vehicle. Or, after sending the alarm prompt, monitor the rising speed of the water level. When the rising speed of the water level exceeds the preset speed, control the vehicle to automatically move the vehicle. For example, when the time interval between the current moment and the moment when the alarm prompt is sent reaches the preset time interval, judge whether there is at least one target area within the preset range centered on the vehicle where the water level is lower than the alarm threshold. For example, collect images of the current environment where the vehicle is located through a camera, and determine whether there is at least one parking space where the water level is lower than the alarm threshold through an image recognition model, and determine the parking space as the target area. When there is at least one target area within the preset range centered on the vehicle where the water level is lower than the alarm threshold, request the user for the automatic driving permission. And the image of the target area collected by the camera can be sent to the user synchronously to facilitate the user's decision-making and improve the user's decision-making efficiency. When the request for automatic driving permission is successful, control the vehicle to drive to the target area with the lowest water level. Another example is that the image collected by the camera can also be used to determine whether there is a parking space with an absolute height higher than the current position, and determine the parking space as the target area. When the target area is detected, request the user for the automatic driving permission. When the request for automatic driving permission is successful, control the vehicle to drive to the target area with the highest absolute height.

[0070] In an embodiment of the present application, to prevent danger, when the water level in the preset area below the vehicle reaches the water level alarm threshold, judge whether the vehicle is currently in a charging state. When the vehicle is currently in a charging state, control the vehicle to disconnect the main positive relay and the main negative relay.

[0071] In another embodiment of the present application, in order not to affect the user's vehicle movement or other vehicle control functions, when the water level in the preset area below the vehicle reaches the water level alarm threshold, it is determined whether the vehicle has an ongoing software update task or a scheduled task to update the software within a preset time period; when the vehicle is in the process of performing a software update operation, the software update operation is suspended; when the vehicle has a scheduled task to update the software within a preset time period, the scheduled task is canceled. Of course, before suspending the software update operation or canceling the scheduled task, an inquiry message can be sent to the user, and the suspension of the software update operation or the cancellation of the scheduled task can be determined based on the user's decision, and the upgrade time can be changed based on the user's decision.

[0072] In addition, when the water level in the preset area below the vehicle reaches the water level alarm threshold, the vehicle sends the vehicle location and a warning message that it is flooded to the cloud platform, so that the cloud platform can send flood warning information to other vehicles or owners of other vehicles within the preset area where the current vehicle is located.

[0073] The beneficial effect of the present application is that when the water level in the preset area below the vehicle reaches the water level alarm threshold, and the vehicle can raise the suspension height of the air suspension system, the vehicle is controlled to raise the suspension height of the air suspension system to increase the height of the vehicle chassis. Since raising the chassis height is equivalent to raising the height of the components that are greatly affected by flooding, the risk of the components on the vehicle being flooded is reduced. In addition, since there is an upper limit to the water level increase, even if the water level rises, there is a maximum water level height. Therefore, the greater the height of the components that are greatly affected by flooding, the more likely it is to be greater than the maximum water level height, thereby reducing the risk of the vehicle being flooded; in addition, even if the height of the components that are greatly affected by flooding after the height is raised is still less than the maximum water level height, raising the height of these components can also delay the time when these components are flooded, buy more time for the owner to move the vehicle independently, and can also reduce the risk of the vehicle being flooded.

[0074] In one embodiment, the above step S101 may be implemented as the following steps A1-A2:

[0075] In step A1, the angle information between the vehicle and the ground and the height information of the air suspension system of the vehicle are obtained, and the air suspension system is a height-adjustable suspension system;

[0076] In step A2, a correspondence table between the vehicle height information and the water level alarm threshold is queried based on the angle information between the vehicle and the ground and the height information of the vehicle's air suspension system to determine the water level alarm threshold related to the vehicle height information, wherein the correspondence table between the vehicle height information and the water level alarm threshold includes the correspondence between the angle information between the vehicle and the ground and the height information of the vehicle's air suspension system and the vehicle's water level alarm threshold.

[0077] In this embodiment, the angle information between the vehicle and the ground and the height information of the vehicle's air suspension system are obtained. The air suspension system is a suspension system with adjustable height. Among them, the angle information between the vehicle and the ground can be directly collected and monitored by the vehicle's sensor system; the height information of the air suspension system refers to the body height or ground clearance set by the suspension system when the vehicle is equipped with an air suspension system, and the body height can be changed by adjusting the air pressure in the airbag. Since both the angle information between the vehicle and the ground and the height of the air suspension system will cause the relative position between the vehicle and the water level to be different, therefore, in this embodiment, the body controller is used to obtain the current angle information between the vehicle and the ground and the height information of the vehicle's air suspension system. Of course, it is also possible to determine the ground height in the current environment of the vehicle by collecting images of the current vehicle environment through a camera, and then determine the angle information between the vehicle and the ground and the height information of the air suspension system. The specific acquisition method is not limited in this embodiment.

[0078] Query the correspondence table between the vehicle height information and the water level alarm threshold according to the angle information between the vehicle and the ground and the height information of the vehicle's air suspension system to determine the water level alarm threshold related to the vehicle height information. Among them, the correspondence table between the vehicle height information and the water level alarm threshold includes the correspondence between the angle information between the vehicle and the ground and the height information of the vehicle's air suspension system and the vehicle water level alarm threshold. In order to determine the vehicle water level alarm threshold, the system pre-stores the correspondence table between the angle information between the vehicle and the ground and the height information of the vehicle's air suspension system to query the vehicle height information and the water level alarm threshold, so as to determine the corresponding vehicle water level alarm threshold under different angle information between the vehicle and the ground and the height of the vehicle air suspension system. Through the slope information and the height information of the air suspension system of the current vehicle, query the correspondence table between the vehicle height information and the water level alarm threshold, and then determine the current vehicle water level alarm threshold.

[0079] In one embodiment, the method can also be implemented as the following steps:

[0080] When the vehicle is not equipped with an air suspension, or the suspension height of the vehicle's air suspension system reaches the maximum suspension height, control the vehicle to drive to a target area with the lowest water level.

[0081] In one embodiment, the method can also be implemented as the following step B1:

[0082] In step B1, when the vehicle is not equipped with an air suspension, or the suspension height of the vehicle's air suspension system reaches the maximum suspension height, send an alarm prompt to the user terminal.

[0083] In this embodiment, it is determined whether the vehicle is equipped with an air suspension system. Since whether different vehicle models are equipped with an air suspension system is pre-determined, it is possible to determine whether the vehicle is equipped with an air suspension system according to the current vehicle model. To determine whether the vehicle chassis can be lifted, when the vehicle is equipped with an air suspension system, the suspension height of the air suspension system is obtained. Specifically, it can be obtained by querying through the vehicle's on-board information system. When the suspension height of the air suspension system reaches the maximum suspension height, it is determined that the vehicle cannot lift the suspension height of the air suspension system; when the suspension height of the air suspension system does not reach the maximum suspension height, it is determined that the vehicle can lift the suspension height of the air suspension system. In addition, when the vehicle is not equipped with an air suspension system, it is determined that the vehicle cannot lift the suspension height of the air suspension system.

[0084] To prevent the vehicle from being flooded, after controlling the vehicle to lift the chassis height, or in the case where the vehicle cannot lift the chassis height, that is, when the vehicle is not equipped with an air suspension or the suspension height of the vehicle's air suspension system reaches the maximum suspension height, an alarm prompt is sent to the user terminal to remind the user to move the vehicle. In addition, after sending the alarm prompt, it is also possible to monitor whether the user moves the vehicle within a preset time, and control the vehicle to automatically move when the user does not move the vehicle. Alternatively, after sending the alarm prompt, monitor the rising speed of the water level, and control the vehicle to move automatically when the rising speed of the water level exceeds the preset speed.

[0085] In one embodiment, after step B1, the method can also be implemented as the following steps C1, C2 or steps C1, C3:

[0086] In step C1, when the time interval between the current moment and the moment when the alarm prompt is sent reaches a preset time interval, it is determined whether there is at least one target area within a preset range centered on the vehicle where the water level is lower than the alarm threshold; in step C2, when there is at least one target area within a preset range centered on the vehicle where the water level is lower than the alarm threshold, control the vehicle to drive to the target area with the lowest water level.

[0087] In step C3, when there is at least one target area within a preset range centered on the vehicle where the water level is lower than the alarm threshold, request the user for the right of autonomous driving; when the request for the right of autonomous driving is successful, control the vehicle to drive to the target area with the lowest water level.

[0088] In this embodiment, in order to further reduce the risk of the vehicle being flooded, after an alarm prompt is issued, it is monitored whether the user moves the vehicle within a preset time, and the vehicle is automatically moved when the user does not move the vehicle. Specifically, when the time interval between the current moment and the moment when the alarm prompt is issued reaches a preset time interval, it is determined whether there is at least one target area within a preset range centered on the vehicle where the water level is lower than the alarm threshold. For example, images of the environment where the current vehicle is located are collected by a camera, and an image recognition model is used to determine whether there is at least one parking space where the water level is lower than the alarm threshold, and the parking space is determined as the target area.

[0089] When there is at least one target area within a preset range centered on the vehicle where the water level is lower than the alarm threshold, control the vehicle to drive to the target area with the lowest water level. Of course, it is also possible to request the user for autonomous driving permission when there is at least one target area within a preset range centered on the vehicle where the water level is lower than the alarm threshold. And, the images of the target area collected by the camera can be sent to the user synchronously to facilitate the user's decision-making and improve the user's decision-making efficiency. When the request for autonomous driving permission is successful, control the vehicle to drive to the target area with the lowest water level.

[0090] Of course, it is also possible to determine whether there is a parking space with an absolute height higher than the current position through the images collected by the camera, and determine the parking space as the target area. When a target area is detected, request the user for autonomous driving permission, and when the request for autonomous driving permission is successful, control the vehicle to drive to the target area with the highest absolute height.

[0091] In one embodiment, the method can also be implemented as the following steps D1-D2:

[0092] In step D1, it is judged whether the vehicle is currently in a charging state;

[0093] In step D2, when the vehicle is currently in a charging state, control the vehicle to disconnect the main positive relay and the main negative relay.

[0094] In this embodiment, when the water level in the preset area below the vehicle reaches the water level alarm threshold, it is judged whether the vehicle is currently in a charging state. When the vehicle is currently in a charging state, control the vehicle to disconnect the main positive relay and the main negative relay.

[0095] In one embodiment, the method can also be implemented as the following steps E1-E3:

[0096] In step E1, it is judged whether the vehicle has an ongoing software update task or a reservation task for software update within a preset time period;

[0097] In step E2, when the vehicle is performing a software update operation, pause the software update operation;

[0098] In step E3, when the vehicle has a reservation task for software update within a preset time period, cancel the reservation task.

[0099] In this embodiment, when the water level in the preset area below the vehicle reaches the water level alarm threshold, in order not to affect the user's vehicle moving or other vehicle control functions, it is determined whether the vehicle has an ongoing software update task or a reservation task for software update within a preset time period; when the vehicle is performing a software update operation, pause the software update operation; when the vehicle has a reservation task for software update within a preset time period, cancel the reservation task.

[0100] Of course, before pausing the software update operation or canceling the reservation task, an inquiry message can be sent to the user, and based on the user's decision, determine whether to pause the software update operation or cancel the reservation task, and change the upgrade time according to the user's decision.

[0101] In one embodiment, when the water level in the preset area below the vehicle reaches the water level alarm threshold, the method further includes F1 - F2:

[0102] In step F1, determine whether there is a target vehicle belonging to the same cloud platform as the vehicle within a preset range centered on the vehicle;

[0103] In step F2, when there is a target vehicle, send a first alarm prompt indicating that the target vehicle is at risk of being flooded to the cloud platform, so that the cloud platform sends a second alarm prompt indicating that the target vehicle is at risk of being flooded to the user terminal corresponding to the target vehicle, where the first alarm prompt includes the identification information and / or location information of the target vehicle.

[0104] In this embodiment, when the water level in the preset area below the vehicle reaches the water level alarm threshold, determine whether there is a target vehicle belonging to the same cloud platform as the vehicle within a preset range centered on the vehicle. Among them, the target vehicle of the same cloud platform can be a vehicle of a preset model. For example, the vehicle can autonomously identify and detect whether there are other vehicles of the same manufacturer around, such as identifying the vehicle logo and the shape contour of the vehicle. Specifically, it can be determined whether there is a vehicle of a preset model by the images collected by the current vehicle's camera, and when there is, determine the vehicle of the preset model as the target vehicle. In addition, a preset signal can be sent from the vehicle to the surrounding vehicles, and when it belongs to the target vehicle of the same cloud platform, a corresponding return signal can be received.

[0105] When the target vehicle exists, send a first alarm prompt indicating that the target vehicle has a risk of being flooded to the cloud platform, so that the cloud platform sends a second alarm prompt indicating that the target vehicle has a risk of being flooded to the user terminal corresponding to the target vehicle. Wherein, the first alarm prompt includes the identification information and / or location information of the target vehicle, and thus the cloud platform can determine the corresponding target vehicle according to the representation information and / or location information of the target vehicle.

[0106] In an embodiment of the present application, a vehicle waterproofing method for a cloud platform is further provided. The method can be implemented as the following steps G1 - G3:

[0107] In step G1, when receiving a first alarm prompt reported by a pre - bound vehicle indicating that the target vehicle has a risk of being flooded, obtain the identification information and / or location information of the target vehicle included in the first alarm prompt;

[0108] In step G2, match the identification information and / or location information of the target vehicle with a vehicle information database to obtain the user terminal corresponding to the target vehicle stored in the vehicle information database;

[0109] In step G3, send a second alarm prompt indicating that the target vehicle has a risk of being flooded to the user terminal corresponding to the target vehicle.

[0110] In this embodiment, when receiving a first alarm prompt reported by a pre - bound vehicle indicating that the target vehicle has a risk of being flooded, obtain the identification information and / or location information of the target vehicle included in the first alarm prompt. Match the identification information and / or location information of the target vehicle with a vehicle information database to obtain the user terminal corresponding to the target vehicle stored in the vehicle information database; for example, when the license plate number of the target vehicle is included in the first alarm prompt information, match the license plate number of the target vehicle with the vehicle information database to determine the user terminal corresponding to the target vehicle. Then send a second alarm prompt indicating that the target vehicle has a risk of being flooded to the user terminal corresponding to the target vehicle. Furthermore, send a second alarm message to the vehicles that have not been flooded temporarily to remind the users of the target vehicles to move their vehicles in advance.
