At present, the failure rate of cars in the process of wading driving has been relatively high, and even traffic accidents will occur frequently, seriously affecting people's lives and property safety. When a car wades, the driving conditions of the vehicle are very different from those in ordinary environments. The water flow will increase the resistance of the vehicle's forward movement, and the water flow will produce thrusts in various directions on the moving car, causing the vehicle to easily slip, the steering wheel of the vehicle is easy to lose control, etc.; in addition, the pressure between the tires and the underwater road surface is reduced, the driving force is limited, and the vehicle's driving is blocked, which will cause traffic accidents and rollovers. Therefore, car wading driving is a very dangerous driving condition.

[0029] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0030] Furthermore, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. Some of the blocks shown in the drawings are functional entities and do not necessarily correspond to physically or logically separate entities.

[0031] It should be noted that the existing technical solutions are aimed at identifying the prompt of alarm information after wading, and there is no good way to reduce the risk of wading conditions. This application uses the vehicle's built-in height sensor to collect the vehicle height signal and combines the vehicle's current speed signal, the status of the air pump, the air tank and the air distribution valve to comprehensively identify that the vehicle is in a wading state. At the same time, combined with the characteristics of the air suspension height adjustment, the vehicle height is raised to the highest level. After the adjustment is completed, the suspension adjustment function is prohibited. After the vehicle leaves the flooded area, the vehicle speed is greater than a certain threshold, and the vehicle height is automatically restored to the original height.

[0032] The embodiments of the present application provide a method, device, equipment and storage medium for processing vehicle wading, which can identify vehicle wading and adjust the height of the vehicle after wading to increase the safety and stability of wading driving, which can greatly reduce the risk of accidents. At the same time, disabling the water adjustment function can reduce the risk of damage to the air spring system.

[0033] In order to achieve the above technical effects, the general idea of ​​this application is as follows:

[0034] A method for handling vehicle wading, the method comprising the steps of:

[0035] S101: Utilize the height sensor of the vehicle's own air suspension to collect the wheel spring height signal, and combine the current vehicle speed, the status of the air pump, the air tank and the air distribution valve to determine whether the vehicle is in a wading state.

[0036] S102: When it is determined that the vehicle is in a wading state, adjust the height of the air suspension to pass through the wading area.

[0037] The embodiments of the present application are further described in detail below in conjunction with the accompanying drawings.

[0038] Reference Figure 1 , Figure 1 FIG. 1 is a flow chart of a method for processing vehicle wading provided by the present invention, such as Figure 1 As shown, the method comprises the steps of:

[0039] Step S101: Utilize the height sensor of the vehicle's own air suspension to collect the wheel spring height signal, and determine whether the vehicle is in a wading state in combination with the current vehicle speed, the status of the air pump, the air tank and the air distribution valve.

[0040] Specifically, the vehicle's own height sensor is used to collect the vehicle's four wheel height signals. At this time, the vehicle's own air suspension controller monitors the four wheel height sensor signals and the current vehicle speed, the vehicle's air pump, the air tank and the switch status of the air distribution valve to determine whether the vehicle is in a wading state. It is understandable that to determine whether the vehicle is in a wading state, it is necessary to use the vehicle's current speed signal, tire height signal, and the switch status of the air pump, the air tank and the air distribution valve. It should be noted that the vehicle's own suspension controller monitors the vehicle's current speed signal, tire height signal, and the switch status of the air pump, the air tank and the air distribution valve. It should be noted that the four wheel height signals are collected by four height sensors, namely the vehicle's left front height sensor, right front height sensor, left rear height sensor and right rear height sensor.

[0041] In one embodiment, when the vehicle speed is greater than a first preset speed and less than a second preset speed, the vehicle air suspension controller monitors the height values ​​of the four wheels and the switching status of the air pump, the air tank, and the air distribution valve; when the air pump, the air tank, and the air distribution valve are all in a closed state, the height values ​​of the four wheels rise simultaneously for a certain period of time, and the rising height is greater than the set threshold, it is judged that the vehicle is in a wading state.

[0042] For easier understanding, let's take an example. When the vehicle speed is greater than 5km / h and less than 40km / h, the air suspension controller monitors the four wheel height sensor signals and the switching status of the air pump, air tank, and air distribution valve. When the air pump, air tank, and air distribution valve are all in a closed state, the four wheel height values ​​rise simultaneously for a certain period of time, and the rising height is greater than a certain value, the air suspension controller sends a vehicle wading signal.

[0043] It should be noted that the air suspension controller monitors the signals of the air pump, air tank, and air distribution valve to determine the status of the air pump, air tank, and air distribution valve, and the current speed of the vehicle is issued through the vehicle IPB.

[0044] In one embodiment, when the vehicle speed is greater than 5km / h and less than 40km / h, the air suspension controller monitors the height of the four wheels and rises simultaneously for 5 seconds; when the rising height value is greater than 8mm and it is determined that the air pump, air tank, and air distribution valve are in the closed state, the controller sends a wading signal to determine that the vehicle is currently in a wading state.

[0045] Optionally, when the four wheels are not rising continuously, the controller will exit monitoring. Only when the four wheels rise simultaneously for 5 seconds and the rising height value is greater than 8mm, will the wading signal be issued.

[0046] Step S102: When it is determined that the vehicle is in a wading state, adjust the height of the air suspension to pass through the wading area.

[0047] Specifically, when the air suspension controller sends a vehicle wading signal, in order to reduce the risk of the vehicle wading, the air suspension controller actively adjusts the air suspension to the highest level height, reduces the wading depth, increases the pressure of the wheels on the road, increases the driving force and grip, and ensures smooth driving; after the adjustment is completed, the air spring adjustment function is prohibited to avoid other adjustments during the wading process, which increases the risk of air pump damage; thereafter, when the vehicle speed is higher than 50km / h, the vehicle wading signal is eliminated, and the air suspension controller restores the vehicle body height to the previous height level.

[0048] In one embodiment, when the vehicle leaves the wading area, the vehicle air suspension is restored to the original height. It can be understood that when the vehicle speed is higher than 50km / h, the vehicle wading signal is eliminated, and the air suspension controller restores the vehicle body height to the previous height level.

[0049] In one embodiment, after the vehicle leaves the wading area, before automatically restoring the vehicle air suspension to the initial height, it also includes determining whether the vehicle has left the wading area according to the current vehicle speed, and when the current vehicle speed is greater than a third preset speed, determining that the vehicle has left the wading area. It is understandable that when the vehicle speed is higher than 50 km / h, the vehicle wading signal disappears, and at this time the air suspension controller restores the vehicle height to the previous height level.

[0050] In one embodiment, when it is determined that the vehicle is in a wading state, the vehicle air suspension is adjusted to the maximum height. It can be understood that when the vehicle air suspension controller identifies the wading state, the vehicle's own suspension controller is used to send a wading signal inside the vehicle air suspension controller, and the vehicle air suspension is adjusted to the maximum height according to the wading signal.

[0051] It should be noted that when the air suspension controller recognizes the wading state, it will send a wading signal inside the controller. After this signal comes out, the suspension controller will increase the vehicle's air suspension level.

[0052] In one embodiment, when it is determined that the vehicle is in a wading state, the vehicle air suspension is adjusted to the maximum height, and then the vehicle air spring is adjusted through the vehicle air suspension controller. It is understandable that when the air suspension controller sends a vehicle wading signal, in order to reduce the risk of the vehicle wading, the air suspension controller actively adjusts the air suspension to the highest level height, reduces the wading depth, increases the wheel pressure on the road surface, increases the driving force and grip, and ensures smooth driving; after the adjustment is completed, the air spring adjustment function is prohibited to avoid other adjustments during the wading process, which increases the risk of air pump damage.

[0053] It should be noted that prohibiting the air spring adjustment function is the internal logic of the suspension controller, because any function has prerequisites to be triggered. When wading is detected, the internal logic of the controller will send a logic signal that cannot be adjusted, so that the execution signal cannot be sent 1, and the air spring cannot be adjusted at this time. It is understandable that the benefit of prohibiting adjustment is to protect the air pump, because the air pump needs to suck air from the outside to inflate the air spring. After wading, it sucks water, which will burn the pump.

[0054] It can be understood that the present application does not require the use of additional sensors, but only requires the use of the vehicle's own height sensor, combined with the vehicle's current speed, the air pump, the air tank, and the switch status of the air distribution valve to determine whether the vehicle is in a wading state.

[0055] In summary, when the vehicle speed is greater than 5km / h and less than 40km / h, the air suspension controller monitors the four wheel height sensor signals and the switch status of the air pump, air tank, and air distribution valve. When the air pump, air tank, and air distribution valve are all in a closed state, the height values ​​of the four wheels rise simultaneously for a certain period of time, and the rising height is greater than a certain value, the air suspension controller sends a vehicle wading signal. When the air suspension controller sends a vehicle wading signal, in order to reduce the risk of wading, the air suspension controller actively adjusts the air suspension to the highest level, reduces the wading depth, increases the wheel pressure on the road, increases the driving force and grip, and ensures smooth driving; after the adjustment is completed, the air spring adjustment function is prohibited to avoid other adjustments during the wading process, which increases the risk of air pump damage; afterwards, when the vehicle speed is higher than 50km / h, the vehicle wading signal is eliminated, and the air suspension controller restores the vehicle height to the previous height level.

[0056] It can be understood that the present application saves the additional sensors required by the prior art solutions to identify vehicle wading, and adds the adjustment of the vehicle height after wading to increase the safety and stability of wading driving, which can greatly reduce the risk of accidents. At the same time, prohibiting the underwater adjustment function can reduce the risk of damage to the air spring system.

[0057] Reference Figure 2 , Figure 2 FIG. 1 is a schematic diagram of a processing device for a vehicle wading provided by the present invention, such as Figure 2 As shown, the device comprises:

[0058] Judgment module 201: It is used to collect wheel spring height signals using the height sensor of the vehicle's own air suspension, and determine whether the vehicle is in a wading state in combination with the current vehicle speed, the status of the air pump, the air tank and the air distribution valve.

[0059] The suspension controller 202 is used to adjust the height of the vehicle's air suspension when it is determined that the vehicle is in a wading state, so as to pass through the wading area.

[0060] Furthermore, in a possible implementation manner, the suspension controller 202 is also used to restore the vehicle air suspension to an initial height after the vehicle leaves the wading area.

[0061] Further, in a possible implementation manner, the judgment module 201 is further configured to, when the vehicle speed is greater than a first preset speed and less than a second preset speed, the vehicle air suspension controller monitors the height values ​​of the four wheels and the switch states of the air pump, the air tank, and the air distribution valve;

[0062] When the air pump, the air tank, and the air distribution valve are all in a closed state, and the height values ​​of the four wheels rise simultaneously for a certain period of time, and the rising height is greater than a set threshold, it is determined that the vehicle is in a wading state.

[0063] Furthermore, in a possible implementation manner, the judgment module 201 is further configured to determine whether the vehicle has left the wading area according to the current speed of the vehicle;

[0064] When the current vehicle speed is greater than the third preset speed, it is determined that the vehicle leaves the wading area.

[0065] Furthermore, in a possible implementation manner, the first preset speed is 5 km / h; the second preset speed is 40 km / h; and the third preset speed is 50 km / h.

[0066] Further, in a possible implementation manner, the suspension controller 202 is further configured to, when the vehicle air suspension controller identifies a wading state, use the vehicle's own suspension controller to send a wading signal inside the vehicle air suspension controller;

[0067] The vehicle air suspension is adjusted to a maximum height according to the wading signal.

[0068] Furthermore, in a possible implementation manner, the suspension controller 202 is also used to adjust the vehicle air spring via a vehicle air suspension controller.
