Description

Technical Field

[0001] This application relates to the field of automotive chassis air suspension, and more particularly to an air suspension control method, device, electronic device, and storage medium. Background Technology

[0002] Currently, most vehicle models use an open-loop design for their air suspension systems, with both intake and exhaust pipes located on the exterior of the vehicle body. When operating, this system draws in air from the atmosphere, processes it, and then sends it to the air supply unit. When the vehicle is driving on flooded roads, the system automatically uses high-pressure gas stored in the air tank or directly drives the air springs through the air supply unit, thereby raising the vehicle's attitude.

[0003] Traditional air suspension also has the function of lifting the vehicle body when wading, but its control logic has certain limitations: in wading scenarios, regardless of the water depth, the system will first use the gas in the air tank to lift the vehicle body; only when the air pressure in the air tank drops to a level insufficient to drive the air springs will it switch to the air supply unit. However, if the water is too deep or the vehicle is traveling at a high speed, the splashing water may exceed the air intake of the air supply unit. In this case, as the air supply unit draws in air, it will also draw water into its interior, leading to corrosion and damage to the air supply unit. Summary of the Invention

[0066] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0067] Traditional air suspension also features vehicle lifting capabilities during wading, but its control logic has limitations: in wading scenarios, regardless of water depth, the system prioritizes lifting the vehicle using gas from the reservoir; only when the reservoir pressure drops insufficient to drive the air springs does it switch to the air supply unit. However, if the water is too deep or the vehicle is traveling at high speed, splashing water may exceed the air supply unit's intake. In this case, the air supply unit, while drawing in air, will also draw in moisture, leading to corrosion and damage. Therefore, this application provides an air suspension control method, device, electronic device, and storage medium.

[0068] This application provides an air suspension control method, such as... Figure 1 As shown, it includes:

[0069] Step S101: Detect whether the vehicle is currently in a state of driving through water;

[0070] In this embodiment of the application, the wading driving state can refer to the state of the wheels driving on the road surface with water accumulation. The vehicle can be equipped with a lidar to collect the current wading depth information of the vehicle, or it can be equipped with a camera to collect road surface images of the wheel area.

[0071] In this step, the wading depth information collected by the lidar can be obtained. If the wading depth information is greater than the first wading depth threshold, it can be determined that the vehicle is currently in a wading driving state. For example, the first wading depth threshold can be 1mm. Alternatively, the road surface image collected by the camera can be obtained to identify whether there is water accumulation in the road surface image (such as identifying whether the wheels are partially obscured by water accumulation or whether there is water splashing). If water accumulation is identified in the road surface image, it can be determined that the vehicle is currently in a wading driving state.

[0072] Step S102: If the vehicle is currently in a water-wading state, obtain water depth data and air pressure data of the air tank in the air suspension.

[0073] In this embodiment of the application, the wading depth data can refer to the distance between the lowest point of the wheel's contact with the road surface and the water surface, that is, the depth to which the wheel is submerged in water, such as... Figure 2 As shown, the air suspension includes: an air tank 1, air springs 2, an air supply unit 3, and a five-way valve 4. The air tank 1 can inflate each air spring 2, and the air supply unit can also inflate each air spring 2. For example, the air supply unit 3 can be an air pump, and the air pressure data is the current gas pressure data in the air tank.

[0074] In this step, wading depth data collected by lidar and air pressure data collected by the pressure measuring device in the air suspension used to measure the gas pressure in the gas tank can be obtained.

[0075] Step S103: Determine the target control object and the anti-water ingress action of the target control object in the air suspension according to the wading depth data and the air pressure data;

[0076] In this embodiment, multiple wading depth ranges and multiple air pressure ranges can be preset. Different wading depth ranges and air pressure ranges correspond to different target control objects and water ingress prevention actions. The target control object can be an air storage tank or an air supply unit, etc. The water ingress prevention action can be to inflate the air springs in the air suspension to prevent water from entering the air supply unit's air inlet by raising the chassis height; or, to disable the air supply unit and close the air inlet of the air supply unit, etc., to prevent water from entering the air supply unit's air inlet.

[0077] In this step, the wading depth data can be compared with the preset wading depth range, and the air pressure data can be compared with the preset air pressure range. Based on the wading depth range where the wading depth data is located and the air pressure range where the air pressure data is located, the corresponding target control object and the water ingress prevention action of the target object can be determined in the air suspension.

[0078] Step S104: Control the target control object in the air suspension to perform a water-proofing action.

[0079] In this step, the air supply unit in the air suspension can be controlled to inflate the air spring, or the air supply unit can be disabled, or the air inlet of the air supply unit can be closed.

[0080] This application embodiment can determine the target control object and the anti-water ingress action of the target control object in the air suspension based on the wading depth data and air pressure data when the vehicle is currently in a wading driving state. It can then control the target control object to perform the anti-water ingress action. By selecting the target control object and anti-water ingress action that are adapted to the current wading situation and air suspension status based on the wading depth data and air pressure data, it can achieve targeted anti-water ingress control of the vehicle's air suspension according to the actual application scenario, thereby preventing water from entering the air intake of the vehicle's air supply unit and thus preventing the air supply unit from rusting and being damaged.

[0081] In another embodiment of this application, step S103 determines the target control object and the water-proofing action of the target control object in the air suspension based on the wading depth data and the air pressure data, such as... Figure 3 As shown, it includes:

[0082] Step S201: Determine the flood control type based on the air pressure data and the wading depth data;

[0083] In this step, the type of water ingress prevention control can be determined by comprehensively considering the air pressure range and the wading depth range of the wading depth data. The types of water ingress prevention control can include: Type 1, Type 2, Type 3, and Type 4. Different types of water ingress prevention control can correspond to different water ingress prevention control strategies, so that water ingress prevention control strategies adapted to vehicle conditions and wading conditions can be used according to different air pressure data and different wading depth data. The water ingress prevention control strategy includes: target control object and water ingress prevention action.

[0084] In one embodiment of this application, step S201 determines the flood ingress control type based on the air pressure data and the wading depth data, such as... Figure 4 As shown, it includes:

[0085] Step S301: Determine whether the air pressure data is greater than a preset air pressure threshold;

[0086] In this embodiment of the application, a preset air pressure threshold can be set in advance. For example, the preset air pressure threshold is 10 bar. In actual applications, the preset air pressure threshold can be set according to actual needs. This invention does not limit this setting.

[0087] In this step, the air pressure data can be compared with a preset air pressure threshold to determine whether the air pressure data is greater than the preset air pressure threshold.

[0088] Step S302: If the air pressure data is greater than a preset air pressure threshold, determine whether the wading depth data is greater than or equal to a first wading depth threshold and less than a second wading depth threshold.

[0089] In this embodiment of the application, a first wading depth threshold and a second wading depth threshold can be preset. The first wading depth threshold is less than the second wading depth threshold. For example, the first wading depth threshold can be 1 mm and the second wading depth threshold can be 300 mm. In actual applications, the first wading depth threshold and the second wading depth threshold can be set according to actual needs. This invention does not limit them.

[0090] In this step, if the air pressure data is greater than a preset air pressure threshold, such as air pressure data greater than 10 bar, it can be further determined whether the wading depth data is within the wading depth range formed by the first wading depth threshold and the second wading depth threshold. For example, it can be determined whether the wading depth data is within the range of 1 mm to 300 mm.

[0091] Step S303: If the wading depth data is greater than or equal to the first wading depth threshold and less than the second wading depth threshold, determine the flood prevention control type as the first type.

[0092] In one embodiment of this application, step S201 determines the flood ingress control type based on the air pressure data and the wading depth data, such as... Figure 5 As shown, it includes:

[0093] Step S401: Determine whether the air pressure data is greater than a preset air pressure threshold;

[0094] Step S402: If the air pressure data is greater than a preset air pressure threshold, determine whether the wading depth data is greater than or equal to a second wading depth threshold and less than a third wading depth threshold.

[0095] In this embodiment of the application, a third wading depth threshold can be preset. The third wading depth threshold is greater than the second wading depth threshold. For example, the third wading depth threshold can be 600mm. In actual applications, the third wading depth threshold can be set according to actual needs. This invention does not limit this setting.

[0096] In this step, if the air pressure data is greater than the preset air pressure threshold, such as air pressure data greater than 10 bar, it can be further determined whether the wading depth data is within the wading depth range formed by the second wading depth threshold and the third wading depth threshold. For example, it can be determined whether the wading depth data is within the range of 300mm-600mm.

[0097] Step S403: If the wading depth data is greater than or equal to the second wading depth threshold and less than the third wading depth threshold, determine the flood ingress control type as the second type.

[0098] In one embodiment of this application, step S201 determines the flood ingress control type based on the air pressure data and the wading depth data, such as... Figure 6 As shown, it includes:

[0099] Step S501: Determine whether the air pressure data is less than or equal to a preset air pressure threshold.

[0100] In this step, the air pressure data can be compared with a preset air pressure threshold to determine whether the air pressure data is less than or equal to the preset air pressure threshold.

[0101] Step S502: If the air pressure data is less than or equal to a preset air pressure threshold, determine whether the wading depth data is greater than or equal to a first wading depth threshold and less than a second wading depth threshold.

[0102] In this step, if the air pressure data is less than or equal to a preset air pressure threshold, such as air pressure data less than or equal to 10 bar, it can be further determined whether the wading depth data is within the wading depth range formed by the first wading depth threshold and the second wading depth threshold. For example, it can be determined whether the wading depth data is within the range of 1 mm to 300 mm.

[0103] Step S503: If the wading depth data is greater than or equal to the first wading depth threshold and less than the second wading depth threshold, determine the flood prevention control type as the third type.

[0104] In one embodiment of this application, step S201 determines the flood ingress control type based on the air pressure data and the wading depth data, such as... Figure 7 As shown, it includes:

[0105] Step S601: Determine whether the air pressure data is less than or equal to a preset air pressure threshold.

[0106] Step S602: If the air pressure data is less than or equal to a preset air pressure threshold, determine whether the wading depth data is greater than or equal to a second wading depth threshold and less than a third wading depth threshold.

[0107] Step S603: If the wading depth data is greater than or equal to the second wading depth threshold and less than the third wading depth threshold, determine the flood ingress control type as the fourth type.

[0108] Step S202: Determine the target control object and the anti-water ingress action of the target control object according to the anti-water ingress control type.

[0109] If the water ingress prevention control type is the first type, the air supply unit in the air suspension is determined as the target control object; the water ingress prevention action of the target control object is determined to be to inflate the air spring in the air suspension.

[0110] In this embodiment, when the air pressure data is greater than a preset air pressure threshold and the wading depth data is within the wading depth range formed by the first wading depth threshold and the second wading depth threshold, the water ingress prevention control type can be determined as the first type. At this time, the air supply unit can be determined as the target control object, and the inflation of the air spring can be determined as the water ingress prevention action.

[0111] If the water ingress prevention control type is the second type, the air tank in the air suspension is identified as the target control object; the water ingress prevention action of the target control object is identified as inflating the air spring in the air suspension.

[0112] In this embodiment, when the air pressure data is greater than a preset air pressure threshold and the wading depth data is within the wading depth range formed by the second wading depth threshold and the third wading depth threshold, the water ingress prevention control type can be determined to be the second type. At this time, the air tank can be determined as the target control object, and the inflation of the air spring can be determined as the water ingress prevention action.

[0113] If the water ingress prevention control type is the third type, the air supply unit in the air suspension is determined to be the target control object; the water ingress prevention action of the target control object is determined to be to inflate the air spring in the air suspension.

[0114] In this embodiment of the application, when the air pressure data is less than or equal to a preset air pressure threshold and the wading depth data is within the wading depth range formed by the first wading depth threshold and the second wading depth threshold, the water ingress prevention control type can be determined to be the third type. At this time, the air supply unit can be determined as the target control object, and the inflation of the air spring can be determined as the water ingress prevention action.

[0115] If the water ingress prevention control type is the fourth type, the air supply unit in the air suspension is determined as the target control object; the water ingress prevention action of the target control object is determined to be to prohibit the air supply unit from working and to close the air inlet of the air supply unit.

[0116] In this embodiment of the application, when the air pressure data is less than or equal to a preset air pressure threshold and the wading depth data is within the wading depth range formed by the second wading depth threshold and the third wading depth threshold, the water ingress prevention control type can be determined to be the fourth type. At this time, the air supply unit can be determined as the target control object, and the operation of the air supply unit can be prohibited. The closing of the air inlet of the air supply unit is determined as the water ingress prevention action.

[0117] In another embodiment of this application, step S104 controls the target control object in the air suspension to perform a water-proofing action, including:

[0118] If the water ingress prevention control type is the first type, the air supply unit in the air suspension is controlled to inflate the air springs until the vehicle chassis height reaches the target height.

[0119] In this embodiment of the application, the target height may refer to the vehicle chassis height when the air spring is fully inflated and the vehicle chassis is raised to its highest position, or the vehicle chassis height when the air spring is inflated to 2 / 3 of its maximum height.

[0120] In this embodiment of the application, when the water ingress control type is the first type, that is, when the air pressure in the air tank is relatively high and the wading depth is relatively low, since there is no risk of water entering the air inlet of the air supply unit, the air supply unit is used to inflate the air spring. This can ensure that the air inlet of the air supply unit does not enter water while retaining the gas in the air tank for use when the vehicle wades into deeper water.

[0121] If the water ingress prevention control type is the second type, the air tank in the air suspension is controlled to inflate the air springs until the vehicle chassis height reaches the target height.

[0122] In this embodiment, when the air pressure in the air tank is high and the wading depth is deep, the air in the air tank is sufficient to inflate the air spring, and there is a risk of water entering the air inlet of the air supply unit. Therefore, by inflating the air spring with the air tank, the vehicle chassis can be raised, ensuring that water does not enter the air inlet of the air supply unit, thereby avoiding corrosion and damage to the air supply unit.

[0123] If the water ingress prevention control type is the third type, the air supply unit in the air suspension is controlled to inflate the air springs until the vehicle chassis height reaches the target height.

[0124] In this embodiment, when the air pressure in the air tank is low and the wading depth is low, since the air in the air tank is insufficient to inflate the air spring, and there is no risk of water entering the air inlet of the air supply unit, the air supply unit can be used to inflate the air spring. This can ensure that water does not enter the air inlet of the air supply unit while retaining the gas in the air tank for use when the vehicle is wading in deeper water.

[0125] If the water ingress prevention control type is the fourth type, the air supply unit in the air suspension is controlled to close, and the air intake of the air supply unit is closed until the vehicle chassis height reaches the target height.

[0126] In this embodiment, when the air pressure inside the air tank is low and the wading depth is large, the air inside the air tank is insufficient to inflate the air spring, and there is a risk of water entering the air inlet of the air supply unit. Therefore, the air supply unit is controlled to shut down, and the air inlet of the air supply unit is closed to ensure that water does not enter the air inlet of the air supply unit, thereby avoiding corrosion and damage to the air supply unit.

[0127] In another embodiment of this application, before step S102, as follows: Figure 8 As shown, the method further includes:

[0128] Step S701: Obtain the current chassis height of the vehicle;

[0129] In this step, the current chassis height can be collected using LiDAR cameras or similar devices.

[0130] Step S702: Determine whether the current chassis height is greater than or equal to the target height;

[0131] Step S703: If the current chassis height is less than or equal to the target height, execute the process of acquiring wading depth data and air pressure data of the air tank in the air suspension.

[0132] Step S704: If the current chassis height is less than the target height, keep the vehicle chassis height unchanged.

[0133] In this embodiment, wading depth data and air pressure data can be acquired only when the current chassis height of the vehicle is low. Then, based on the wading depth data and air pressure data, the target control object and the anti-water ingress action of the target control object are determined in the air suspension, and the target control object is controlled to perform the anti-water ingress action. Otherwise, the chassis height of the vehicle is not adjusted in order to save vehicle resources.

[0134] In another embodiment of this application, an air suspension control device is also provided, such as... Figure 9 As shown, it includes:

[0135] Detection module 11 is used to detect whether the vehicle is currently driving through water;

[0136] The acquisition module 12 is used to acquire wading depth data and air pressure data of the air tank in the air suspension if the vehicle is currently in a wading driving state.

[0137] The determination module 13 is used to determine the target control object and the anti-water ingress action of the target control object in the air suspension based on the wading depth data and the air pressure data.

[0138] Control module 14 is used to control the target control object in the air suspension to perform water ingress prevention actions.

[0139] In another embodiment of this application, an electronic device is also provided, including a processor, a communication interface, a memory, and a communication bus, wherein the processor, the communication interface, and the memory communicate with each other through the communication bus.

[0140] Memory, used to store computer programs;

[0141] The processor, when executing a program stored in memory, implements the air suspension control method described in any of the foregoing method embodiments.

[0142] The electronic device provided in this embodiment of the invention allows the processor to execute a program stored in the memory. When the vehicle is currently in a wading driving state, the processor can determine the target control object and the anti-water ingress action of the target control object in the air suspension based on the wading depth data and air pressure data, and control the target control object to perform the anti-water ingress action. By selecting the target control object and anti-water ingress action that are adapted to the current wading situation and air suspension status based on the wading depth data and air pressure data, the anti-water ingress control of the vehicle's air suspension can be targeted according to the actual application scenario, preventing water from entering the air intake of the vehicle's air supply unit, thereby preventing the air supply unit from rusting and being damaged.
