Description

Technical Field

[0001] The present application relates to the field of vehicles, and more specifically, to a vehicle control method, a device, a vehicle and a storage medium in the field of vehicles. Background Art

[0002] In some cities or areas with heavy rainfall, and roads with relatively simple drainage facilities, when there is short-term heavy rainfall or continuous rainfall, it is easy to cause water accumulation on the roads. If the vehicle is parked in these places, the accumulated water can easily submerge the vehicle, causing corresponding losses to the owner. In the relevant scheme, the amount of rainfall collected by the rainfall monitoring sensor is used to control the suspension components of the vehicle. However, after the vehicle is powered off, the risk of the vehicle being soaked cannot be avoided. Summary of the invention

[0003] The present application provides a vehicle control method, device, vehicle and storage medium. The method adjusts a suspension component according to an acquired rainfall prediction parameter and a first suspension height determined by a first water accumulation height detected by a water level monitoring sensor, thereby improving the accuracy of pre-adjustment of the suspension component.

[0004] In a first aspect, a control of a vehicle is provided, the vehicle comprising a rain monitoring sensor and a water level monitoring sensor, the method comprising: obtaining driving behavior information of a driver; if it is determined based on the driving behavior information that the driver has an intention to perform a power-off operation, obtaining a rain prediction parameter of an environment space where the vehicle is located and a first water accumulation height collected by the water level monitoring sensor, and determining a first suspension height of a suspension component of the vehicle based on the first water accumulation height and the rain prediction parameter; if it is determined based on the driving behavior information that the driver has no intention to perform a power-off operation, obtaining a rain parameter collected by the rain monitoring sensor and a second water accumulation height collected by the water level monitoring sensor, and determining a first suspension height of a suspension component of the vehicle based on the rain parameter and the second water accumulation height; and controlling the height of the suspension component to be adjusted to the first suspension height.

[0005] In an embodiment of the present application, by determining the first suspension height of the suspension assembly of the vehicle based on the rainfall prediction parameter and the first water accumulation height collected by the water level monitoring sensor when it is determined that the driver has the intention to perform the power-off operation, since the suspension assembly is adjusted in advance according to the first suspension height before the driver performs the power-off operation, it can be avoided that the driver is unable to adjust the suspension assembly after performing the power-off operation, and the suspension assembly is adjusted according to the first suspension height determined by the acquired rainfall prediction parameter and the first water accumulation height detected by the water level monitoring sensor, thereby improving the accuracy of pre-adjusting the suspension assembly; by adjusting the height of the suspension assembly according to the first suspension height determined by the rainfall parameter collected by the rainfall monitoring sensor and the second water accumulation height collected by the water level monitoring sensor when it is determined that the driver has no intention to perform the power-off operation, since the first suspension height is determined by combining the actually collected rainfall parameter and the second water accumulation height of the environmental space where the vehicle is located, the suspension assembly can be adjusted according to the actual situation, thereby improving the accuracy of adjusting the suspension height.

[0006] In combination with the first aspect, in some possible implementations, determining a first suspension height of a suspension component of a vehicle based on a rainfall parameter and a second water accumulation height includes: obtaining a third water accumulation height collected by a water level monitoring sensor at a historical moment; determining the difference between the second water accumulation height and the third water accumulation height as a change height of the second water accumulation height within a historical time threshold, wherein the historical moment is the starting moment of the historical time threshold; and determining the first suspension height of the suspension component of the vehicle based on the obtained rainfall parameter and the change height.

[0007] By adopting the above scheme, the first suspension height of the suspension component is determined by obtaining the rainfall parameter and the difference between the third water accumulation height and the second water accumulation height collected at the historical moment to obtain the change height of the second water accumulation height within the historical time length threshold. Since the change height of the water level within the historical time length threshold can reflect the water accumulation height in the future period of time to a certain extent, the accuracy of the determined first suspension height of the suspension component is improved.

[0008] In combination with the first aspect, in some possible implementations, the rainfall parameters include current rainfall parameters and historical rainfall parameters collected within a historical time threshold, and a first suspension height of a suspension component of the vehicle is determined based on the rainfall parameters and the change height, including: determining a comparison result of the current rainfall parameters and the historical rainfall parameters; determining a second suspension height of the suspension component of the vehicle based on the change height; and determining the first suspension height of the suspension component based on the comparison result and the second suspension height.

[0009] By adopting the above scheme, the first suspension height can be adjusted by comparing the current rainfall parameters with the historical rainfall parameters. Since the predicted first suspension height is adjusted according to the actually collected environmental space parameters, the accuracy of the first suspension height can be improved.

[0010] In combination with the first aspect, in some possible implementations, the first suspension height of the suspension assembly is determined based on the comparison result and the second suspension height, including: if the comparison result is that the current rainfall parameter is greater than the historical rainfall parameter, then determining the difference between the current rainfall parameter and the historical rainfall parameter, and determining the suspension height change corresponding to the difference; determining the sum of the suspension height change and the second suspension height as the first suspension height of the suspension assembly.

[0011] By adopting the above scheme, when the comparison result of the current rainfall parameter and the historical rainfall parameter is that the current rainfall parameter is greater than the historical rainfall parameter, the second suspension height determined by changing the height is adjusted to obtain the first suspension height, thereby avoiding the problem that when the current rainfall parameter is greater than the historical rainfall parameter, the suspension height is still adjusted according to the second suspension height determined by changing the height, and the water level change is much greater than the second suspension height, resulting in the vehicle chassis being soaked.

[0012] In combination with the first aspect, in some possible implementations, the first suspension height of the suspension assembly is determined based on the comparison result and the second suspension height, including: if the comparison result is that the current rainfall parameter is less than or equal to the historical rainfall parameter, then the second suspension height is determined as the first suspension height of the suspension assembly.

[0013] By adopting the above scheme, when the comparison result of the current rainfall parameter and the historical rainfall parameter is that the current rainfall parameter is less than the historical rainfall parameter, the second suspension height is determined to be the first suspension height. Since the current rainfall will not cause the water level change to be greater than the predicted change height, the second suspension height can be directly determined to be the first suspension height, thereby improving the accuracy of the obtained first suspension height.

[0014] In combination with the first aspect, in some possible implementations, a first suspension height of a suspension assembly of a vehicle is determined based on a first water accumulation height and a rainfall prediction parameter, including: determining a rainfall prediction level of an environmental space in which the vehicle is located based on the rainfall prediction parameter; determining a chassis height level of the vehicle corresponding to the rainfall prediction level; and determining the first suspension height of the suspension assembly based on the chassis height level and the first water accumulation height.

[0015] By adopting the above scheme, the rainfall prediction level is determined by the rainfall prediction parameters, and the corresponding chassis height level is determined by the rainfall prediction level, and then the first suspension height of the suspension assembly is determined by the chassis height level and the first water accumulation height. Since the first suspension height is determined jointly by the rainfall prediction parameters and the actual first water accumulation height, combined with the water accumulation situation in the environmental space where the vehicle is located, the first suspension height can be accurately determined to prevent the chassis of the vehicle from being soaked.

[0016] In combination with the first aspect, in some possible implementations, before controlling the height of the suspension component to be adjusted to the first suspension height, it also includes: displaying activation request information containing the first suspension height on the display interface of the vehicle; if confirmation information is obtained, activating the suspension component, and executing the height control of the suspension component to be adjusted to the first suspension height, and the confirmation information is triggered by the user based on the activation request instruction displayed on the display interface.

[0017] By adopting the above scheme, before controlling the suspension component, an activation request including the first suspension height is displayed in the display interface of the vehicle, and the suspension component is controlled to be adjusted according to the first suspension height only after receiving the user's confirmation information. Since the suspension component is controlled to be adjusted according to the first suspension height only after receiving the user's confirmation information, the user can choose whether to adjust the suspension component according to his or her driving needs, thereby improving the user experience.

[0019] An acquisition unit, used for acquiring driving behavior information of a driver;

[0020] A first determination unit is used to obtain a rainfall prediction parameter of an environment space where the vehicle is located and a first water accumulation height collected by a water level monitoring sensor if it is determined based on the driving behavior information that the driver has an intention to perform a power-off operation, and determine a first suspension height of a suspension assembly of the vehicle based on the first water accumulation height and the rainfall prediction parameter;

[0021] a second determination unit, configured to obtain a rainfall parameter collected by a rainfall monitoring sensor and a second water accumulation height collected by a water level monitoring sensor if it is determined based on the driving behavior information that the driver has no intention to perform a power-off operation, and determine a first suspension height of a suspension assembly of the vehicle based on the rainfall parameter and the second water accumulation height;

[0022] The control unit is used to control the height of the suspension assembly to be adjusted to a first suspension height.

[0023] In a third aspect, a vehicle is provided, comprising: a memory for storing executable program code;

[0024] A processor is used to call and run executable program code from a memory so that the vehicle executes the method in the above-mentioned first aspect or any possible implementation of the first aspect.

[0026] In a fifth aspect, a computer-readable storage medium is provided, which stores a computer program code.

[0034] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0035] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0036] Please refer to Figure 1 , Figure 1 A schematic diagram of a scenario of a vehicle control method provided in an embodiment of the present application. In the related art, vehicles are usually equipped with rain monitoring sensors to monitor precipitation in real time and automatically adjust suspension components to prevent the vehicle from being soaked. However, this solution still has a potential problem. Since the rain monitoring sensor and the suspension adjustment system usually require power supply to operate, if the driver controls the vehicle to perform a power-off operation, the suspension system will lose its adjustment function and cannot adjust the vehicle's suspension, thereby failing to accurately prevent the risk of the vehicle being soaked.

[0037] Therefore, in the present application, by determining the first suspension height of the suspension assembly of the vehicle based on the rainfall prediction parameters and the first water accumulation height collected by the water level monitoring sensor when it is determined that the driver has the intention to perform the power-off operation, since the suspension assembly is adjusted in advance according to the first suspension height before the driver performs the power-off operation, it can be avoided that the driver is unable to adjust the suspension assembly after performing the power-off operation, and the suspension assembly is adjusted according to the first suspension height determined by the acquired rainfall prediction parameters and the first water accumulation height detected by the water level monitoring sensor, thereby improving the accuracy of pre-adjusting the suspension assembly; by adjusting the height of the suspension assembly according to the first suspension height determined by the rainfall parameters collected by the rainfall monitoring sensor and the second water accumulation height collected by the water level monitoring sensor when it is determined that the driver has no intention to perform the power-off operation, since the first suspension height is determined by combining the actually collected rainfall parameters and the second water accumulation height of the environmental space where the vehicle is located, the suspension assembly can be adjusted according to the actual situation, thereby improving the accuracy of adjusting the suspension height.

[0038] based on Figure 1 The flow chart shown below will be combined with Figure 2-Figure 4 , the vehicle control method provided in the embodiment of the present application is introduced in detail.

[0039] See also Figure 2 , is a flow chart of a vehicle control method provided in an embodiment of the present application. Figure 2 As shown, the method of the embodiment of the present application may include the following steps S101-S104.

[0040] S101, obtaining driving behavior information of a driver;

[0041] In one embodiment, the driving behavior information is the behavior characteristics of the driver in the process of using the vehicle, and the driving behavior information of the driver can be obtained through the vehicle's dashboard, sensor, camera, etc. For example, in the embodiment of the present application, the driving behavior information of the driver includes gear shifting behavior information, accelerator pedaling behavior, brake pedaling behavior, phone call behavior, parking gear, etc.

[0042] S102, if it is determined based on the driving behavior information that the driver has an intention to perform a power-off operation, obtaining a rainfall prediction parameter of the environment space where the vehicle is located and a first water accumulation height collected by a water level monitoring sensor, and determining a first suspension height of a suspension assembly of the vehicle based on the first water accumulation height and the rainfall prediction parameter;

[0043] In one embodiment, the power-off operation intention refers to the operation that the driver intends to shut down the vehicle's power system; the environmental space is the space of the area where the vehicle is currently located; and the rainfall prediction parameter is the predicted rainfall amount. Optionally, the vehicle can send the current location information to the meteorological data platform through the network connection module to obtain the rainfall prediction parameters of the space environment where it is located in the future.

[0044] In some implementations, the driver's driving behavior information is obtained through the gear information displayed on the instrument panel to indicate that the vehicle is in the parking gear, and then it is determined that the driver intends to perform a power-off operation.

[0045] In other embodiments, when the driver's driving behavior information indicates that parking is completed, it can be determined by using sensors such as radars or cameras in front and behind the vehicle to determine that the vehicle is completely parked in the parking space and the position is suitable. If so, it is determined that the driver has the intention to perform the power-off operation.

[0046] In some embodiments, a water level monitoring sensor installed at the bottom of the vehicle can directly contact the accumulated water that may enter the vehicle, thereby accurately measuring the first accumulated water height. In addition, the first accumulated water height can also be obtained by multiple water level monitoring sensors, wherein the multiple water level monitoring sensors can be respectively arranged at the front of the vehicle to monitor the wading position of the front of the vehicle and at the rear of the vehicle to monitor the wading position of the rear of the vehicle.

[0047] Specifically, after obtaining the first water accumulation height and rainfall prediction parameter, if it is determined that the rainfall prediction parameter is greater than the predicted rainfall threshold, and the first water accumulation height is greater than the water accumulation height threshold, the first suspension height of the vehicle's suspension assembly is determined to be a preset height.

[0048] Exemplarily, the first water accumulation height may be 50 millimeters (mm), the rainfall prediction parameter is 80 mm, the first water accumulation height is greater than the water accumulation height threshold (20 mm), and the rainfall prediction parameter is greater than the predicted rainfall threshold (30 mm). Since the first water accumulation height is high and the rainfall prediction parameter is large, it is determined that the vehicle is at risk of chassis being soaked in water, and the height of the suspension assembly is increased according to the first suspension height as the preset height (160 mm).

[0049] It is understandable that after the driver triggers the power-off operation, the vehicle will no longer be in a drivable state, and related systems (such as motors, drives, etc.) will stop working. At this time, the vehicle will not be able to drive, accelerate, brake, control the lifting and lowering of suspension components, etc.

[0050] In an embodiment of the present application, by predicting the driver's power-off operation based on the driver's driving behavior information, the first suspension height of the vehicle's suspension assembly is determined based on rainfall prediction parameters and water level monitoring data, so that the suspension assembly is controlled to adjust to the first suspension height before the driver performs the power-off operation, thereby avoiding the situation where the vehicle is unable to raise the suspension assembly after the driver performs the power-off operation, resulting in the chassis of the vehicle being soaked.

[0051] S103, if it is determined based on the driving behavior information that the driver has no intention to perform a power-off operation, obtaining a rainfall parameter collected by a rainfall monitoring sensor and a second water accumulation height collected by a water level monitoring sensor, and determining a first suspension height of a suspension assembly of the vehicle based on the rainfall parameter and the second water accumulation height;

[0052] In one embodiment, if it is determined that the driver does not have the above-mentioned driving behavior information of engaging the parking gear or completing parking, and it is determined that the driver has no intention to perform the power-off operation, that is, the driver will not trigger the power-off operation within a certain period of time, the vehicle's rainfall parameters and the second water accumulation height can be obtained in real time through the rainfall monitoring sensor and the water level monitoring sensor.

[0053] Optionally, in the embodiment of the present application, the rain monitoring sensor can be installed near the rearview mirror of the vehicle or on the upper part of the windshield. These positions can better monitor the falling conditions of rain and ensure that the rain monitoring sensor can receive enough reflected light to judge the size of the rain. It can also avoid the rain monitoring sensor from being directly interfered by weather factors such as wind, rain, and snow, thereby improving its accuracy and stability. It is understandable that, considering the influence of the parking position of the vehicle, for example, if there is an obstruction on one side where the rain monitoring sensor is installed, the rain monitoring sensor cannot accurately obtain the rainfall parameters. Therefore, in the embodiment of the present application, rain monitoring sensors can also be installed at relative positions outside the vehicle to improve the accuracy of the obtained rainfall parameters.

[0054] Specifically, in an embodiment of the present application, the first suspension height of the suspension assembly of the vehicle is determined based on the rainfall parameter and the second water accumulation height: after obtaining the second water accumulation height and the rainfall parameter, if it is determined that the rainfall parameter is greater than the rainfall threshold, and the second water accumulation height is greater than the height threshold, then the first suspension height of the suspension assembly of the vehicle is determined to be a preset height.

[0055] Exemplarily, the second water accumulation height can be 50 millimeters (mm), the rainfall parameter is 80 mm, the second water accumulation height is greater than the height threshold (20 mm), and the rainfall parameter is greater than the rainfall threshold (30 mm). Since the second water accumulation height is high and the rainfall parameter is large, it is determined that the vehicle is at risk of chassis being soaked in water, then the height of the suspension assembly is increased according to the first suspension height as the preset height (160 mm).

[0056] S104, controlling the height of the suspension assembly to be adjusted to a first suspension height.

[0057] In one embodiment, if it is determined that the driver intends to perform a power-off operation, after determining the first suspension height of the vehicle's suspension assembly according to the rainfall prediction parameters of the environment space where the vehicle is located and the first water accumulation height collected by the water level monitoring sensor, if the driver triggers the power-off operation during the process of the vehicle controlling the suspension assembly to adjust according to the first suspension height (the adjustment has not been completed), since the adjustment of the suspension assembly according to the first suspension height has not been completed at this time, the vehicle can be controlled to delay the power-off operation until the adjustment of the suspension assembly is completed. Optionally, if it is determined that the vehicle needs to be controlled to delay the power-off operation, a prompt message is sent to remind the driver that the current vehicle is adjusting the suspension assembly, delay the power-off operation, and inform the driver of the vehicle's current operation, thereby improving the driver's user experience.

[0058] In an embodiment of the present application, by determining the first suspension height of the suspension assembly of the vehicle based on the rainfall prediction parameter and the first water accumulation height collected by the water level monitoring sensor when it is determined that the driver has the intention to perform the power-off operation, since the suspension assembly is adjusted in advance according to the first suspension height before the driver performs the power-off operation, it can be avoided that the driver is unable to adjust the suspension assembly after performing the power-off operation, and the suspension assembly is adjusted according to the first suspension height determined by the acquired rainfall prediction parameter and the first water accumulation height detected by the water level monitoring sensor, thereby improving the accuracy of pre-adjusting the suspension assembly; by adjusting the height of the suspension assembly according to the first suspension height determined by the rainfall parameter collected by the rainfall monitoring sensor and the second water accumulation height collected by the water level monitoring sensor when it is determined that the driver has no intention to perform the power-off operation, since the first suspension height is determined by combining the actually collected rainfall parameter and the second water accumulation height of the environmental space where the vehicle is located, the suspension assembly can be adjusted according to the actual situation, thereby improving the accuracy of adjusting the suspension height.

[0059] See also Figure 3 , is a flow chart of a vehicle control method provided in an embodiment of the present application. Figure 3 As shown, the method of the embodiment of the present application may include the following steps S201-S207.

[0060] S201, obtaining driving behavior information of the driver;

[0061] S202, if it is determined based on the driving behavior information that the driver has an intention to perform a power-off operation, obtaining a rainfall prediction parameter of the environment space where the vehicle is located and a first water accumulation height collected by a water level monitoring sensor, and determining a first suspension height of a suspension assembly of the vehicle based on the first water accumulation height and the rainfall prediction parameter;

[0062] S203, if it is determined based on the driving behavior information that the driver has no intention to perform a power-off operation, obtaining a rainfall parameter collected by a rainfall monitoring sensor and a second water accumulation height collected by a water level monitoring sensor;

[0063] Specifically, in the embodiment of the present application, when it is determined that the driver's driving behavior information has an intention to perform a power-off operation, the specific steps of determining the first suspension height; and when it is determined that the driver's driving behavior information has no intention to perform a power-off operation, the specific steps of obtaining the rainfall parameters collected by the rainfall monitoring sensor and the second water accumulation height collected by the water level monitoring sensor, please refer to the description of steps S101-S103 in the embodiment of the above specification, which will not be repeated here.

[0064] S204, obtaining a third water accumulation height collected by the water level monitoring sensor at a historical moment;

[0065] In one embodiment, after determining that the driver has no intention to perform a power-off operation and the rainfall parameters and the second water accumulation height are collected, it is necessary to obtain the change height of the second water accumulation within the historical time threshold from the current moment, and it is necessary to obtain the starting moment of the historical time threshold, that is, the third water accumulation height detected at the historical moment.

[0066] It can be understood that in an embodiment of the present application, if multiple second water accumulation heights and third water accumulation heights are collected by multiple water level monitoring sensors, the water accumulation height obtained by averaging the multiple second water accumulation heights and the multiple third water accumulation heights is determined as the second water accumulation height and the third water accumulation height for calculating the changing height.

[0067] S205, determining the difference between the second water accumulation height and the third water accumulation height as the change height of the second water accumulation height within the historical time threshold, wherein the historical moment is the starting moment of the historical time threshold;

[0068] In one embodiment, after the second water accumulation height and the third water accumulation height are collected, the difference between the second water accumulation height and the third water accumulation height is calculated, and then the change height of the second water accumulation height within the historical time threshold is determined. It can be understood that by calculating the change height of the second water accumulation height within the historical time threshold, the water accumulation height of the environment space where the vehicle is located in the future period of time can be calculated.

[0069] For example, if the second water accumulation height is collected to be 180 mm and the third water accumulation height is collected to be 140 mm, it can be determined that the change in height of the second water accumulation height within the historical time threshold is 40 mm.

[0070] S206, determining a first suspension height of a suspension assembly of the vehicle based on the obtained rainfall parameter and the change height;

[0071] In one embodiment, the first suspension height of the suspension component of the vehicle is determined by changing the height and the rainfall parameter obtained by the rainfall monitoring sensor. When it is determined that the rainfall parameter is greater than the rainfall threshold, it is determined that the suspension component is adjusted up according to the changed height based on the current suspension height, that is, the first suspension height is the sum of the changed height and the current suspension height.

[0072] Furthermore, the rainfall parameters include current rainfall parameters and historical rainfall parameters collected within a historical time threshold, and a first suspension height of a suspension component of the vehicle is determined based on the rainfall parameters and the change height, including: determining a comparison result of the current rainfall parameters and the historical rainfall parameters, determining a second suspension height of the suspension component of the vehicle based on the change height, and determining the first suspension height of the suspension component based on the comparison result and the second suspension height.

[0073] Specifically, the current rainfall parameter is the rainfall amount collected by the rainfall monitoring sensor at the current moment; the historical rainfall parameter is the rainfall amount collected within the historical duration threshold. Optionally, in an embodiment of the present application, multiple historical rainfall parameters within the historical duration threshold can be obtained at preset time intervals, thereby obtaining the changes in the historical rainfall parameters at multiple moments within the historical duration threshold, thereby improving the accuracy of the comparison results obtained when comparing the historical rainfall parameters with the current rainfall parameters. Optionally, in determining the second suspension height of the suspension assembly of the vehicle based on the change height, specifically, the sum of the change height and the suspension height of the current suspension assembly is the second suspension height.

[0074] Further, if the comparison result is that the current rainfall parameter is greater than the historical rainfall parameter, the difference between the current rainfall parameter and the historical rainfall parameter is determined, and the suspension height change corresponding to the difference is determined, and the sum of the suspension height change and the second suspension height is determined to be the first suspension height of the suspension assembly.

[0075] Optionally, in an embodiment of the present application, the difference between the current rainfall parameter and the historical rainfall parameter can be pre-associated with the suspension height change, so that when the difference between the current rainfall parameter and the historical rainfall parameter is determined, the suspension height change can be determined.

[0076] For example, if the difference is [0, 10) mm, the corresponding suspension height change is 3 mm; if the difference is [10, 25) mm, the corresponding suspension height change is 5 mm; if the difference is [25, 50) mm, the corresponding suspension height change is 10 mm. If the current rainfall parameter is 90 mm and the historical rainfall parameter is 60 mm, it is determined that the current rainfall parameter is greater than the historical rainfall parameter, and it is determined that the difference between the current rainfall parameter and the historical rainfall parameter is 30 mm, then it can be determined that the suspension height change corresponding to the difference between the current rainfall parameter and the historical rainfall parameter is 10 mm. If the second suspension height is 180 mm, the first suspension height is determined to be 190 mm.

[0077] Further, if the comparison result is that the current rainfall parameter is less than or equal to the historical rainfall parameter, the second suspension height is determined to be the first suspension height of the suspension assembly.

[0078] For example, if the current rainfall parameter is 50 mm and the historical rainfall parameter is 20 mm, it is determined that the current rainfall parameter is less than the historical rainfall parameter, and it is determined that the current rainfall is decreasing. The height of the suspension assembly can be directly adjusted according to the second suspension height determined by changing the height, that is, the second suspension height is the first suspension height.

[0079] It is understandable that when it is determined that the current rainfall parameter is less than the historical rainfall parameter, it can be determined that the second suspension height determined by changing the height is sufficient to cope with the current rainfall and water level conditions, and there is no need to adjust the second suspension height.

[0080] It can be understood that in the embodiment of the present application, if multiple historical rainfall parameters are obtained, the average value of the historical rainfall parameters is calculated as the historical rainfall parameter to be compared with the current rainfall parameter.

[0081] S207, controlling the height of the suspension assembly to be adjusted to a first suspension height.

[0082] In an embodiment of the present application, the first suspension height of the suspension component is determined by obtaining the difference between the rainfall parameter and the third water accumulation height and the second water accumulation height collected at the historical moment, and obtaining the change height of the second water accumulation height within the historical time threshold. Since the change height of the water level within the historical time threshold can reflect the water accumulation height in a future period of time to a certain extent, the accuracy of the determined first suspension height of the suspension component is improved; and the first suspension height can be adjusted by comparing the current rainfall parameter with the historical rainfall parameter. Since the first suspension height obtained by prediction is adjusted by the actually collected environmental space parameter, the accuracy of the first suspension height can be improved; and the comparison between the current rainfall parameter and the historical rainfall parameter is carried out. When the comparison result of the numbers is that the current rainfall parameter is greater than the historical rainfall parameter, the second suspension height determined by the change in height is adjusted to obtain the first suspension height, thereby avoiding the problem that when the current rainfall parameter is greater than the historical rainfall parameter, the suspension height is still adjusted according to the second suspension height determined by the change in height, and the change in water level is much greater than the second suspension height, resulting in the vehicle chassis being soaked; and when the comparison result of the current rainfall parameter and the historical rainfall parameter is that the current rainfall parameter is less than the historical rainfall parameter, the second suspension height is determined to be the first suspension height. Since the current rainfall will not cause the change in water level to be greater than the predicted change in height, the second suspension height can be directly determined to be the first suspension height, thereby improving the accuracy of the obtained first suspension height.

[0083] See also Figure 4 , is a flow chart of a vehicle control method provided in an embodiment of the present application. Figure 4 As shown, the method of the embodiment of the present application may include the following steps S301-S303.

[0084] S301, determining a rainfall prediction level of an environment space where a vehicle is located based on rainfall prediction parameters;

[0085] S302, determining a chassis height level of the vehicle corresponding to the rainfall forecast level;

[0086] S303: Determine a first suspension height of the suspension assembly based on the chassis height level and the first water accumulation height.

[0087] In one embodiment, when the driver intends to perform a power-off operation, the rainfall prediction level is determined by the rainfall prediction parameters. In the embodiment of the present application, the rainfall prediction level is divided into four levels, including light rain level, moderate rain level, heavy rain level, and torrential rain level. Different rainfall prediction levels correspond to different rainfall prediction parameters. For example, the rainfall prediction parameter corresponding to the light rain level is [0, 30); the rainfall prediction parameter corresponding to the moderate rain level is [30, 50); the rainfall prediction parameter corresponding to the heavy rain level is [50, 70); the rainfall prediction parameter corresponding to the torrential rain level is [70, 120) in units of mm. The chassis height level is divided into three levels, namely the first height level, the second height level, and the third height level. The chassis height level corresponding to the light rain level and the moderate rain level is determined to be the first height level, the chassis height level corresponding to the heavy rain level is the second height level, and the chassis height level corresponding to the rainstorm level is the third height level. Furthermore, the adjustment height corresponding to the first height level is determined to be 30mm, the adjustment height corresponding to the second height level is 60mm, and the adjustment height corresponding to the third height level is 100mm. Furthermore, the sum of the adjustment height and the first water accumulation height is determined as the first suspension height of the suspension assembly.

[0088] Further, in an embodiment of the present application, activation request information including the first suspension height is displayed on the display interface of the vehicle, and optionally, the activation request information carrying the first suspension height can also be broadcasted by voice. The user triggers the confirmation information through a button on the display interface or other preset confirmation methods. After the vehicle obtains the confirmation information, it activates the suspension component and controls the height of the suspension component to be adjusted to the first suspension height, wherein the confirmation information is triggered by the user based on the activation request instruction displayed on the display interface.

[0089] In an embodiment of the present application, a rainfall prediction level is determined by rainfall prediction parameters, and a corresponding chassis height level is determined by the rainfall prediction level, and then a first suspension height of the suspension assembly is determined by the chassis height level and the first water accumulation height. Since the first suspension height is determined by the rainfall prediction parameters and the actual first water accumulation height, combined with the water accumulation situation in the environmental space where the vehicle is located, the first suspension height can be accurately determined to avoid the chassis of the vehicle being soaked; and before controlling the suspension assembly, an activation request including the first suspension height is displayed on the display interface of the vehicle, and the suspension assembly is controlled to be adjusted according to the first suspension height only after receiving the user's confirmation information. Since the suspension assembly is controlled to be adjusted according to the first suspension height only after receiving the user's confirmation information, the user can choose whether to adjust the suspension assembly according to his or her driving needs, thereby improving the user experience.

[0090] The following will be combined Figure 5-Figure 6 , the vehicle control device provided in the embodiment of the present application is introduced in detail.

[0098] The first determining subunit 133 is used to determine a first suspension height of a suspension assembly of the vehicle based on the obtained rainfall parameter and the change height.

[0099] Optionally, the first determining subunit 133 is specifically configured to:

[0100] Determine the comparison results of current rainfall parameters and historical rainfall parameters;

[0101] determining a second suspension height of a suspension assembly of the vehicle based on the changed height;

[0103] Optionally, the first determining subunit 133 is specifically configured to:

[0104] If the comparison result is that the current rainfall parameter is greater than the historical rainfall parameter, then the difference between the current rainfall parameter and the historical rainfall parameter is determined, and the change in suspension height corresponding to the difference is determined;

[0105] The sum of the suspension height change and the second suspension height is determined as the first suspension height of the suspension assembly.

[0106] Optionally, the first determining subunit 133 is specifically configured to:
