[0024] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0025] With the advancement of intelligent and electrified vehicles, the complexity and integration of vehicle electronic systems have increased significantly, while the reliability requirements for their operating environments have also become increasingly stringent. As a critical component, the vehicle chassis can be susceptible to water intrusion due to driving through water, heavy rain, or seal failure. This can lead to electrical short circuits, sensor failure, and even high-voltage system failure, seriously impacting driving safety. Therefore, real-time monitoring of chassis water intrusion and accurate determination of water intrusion depth are crucial for vehicle safety and fault warning.

[0026] Currently, vehicle water ingress detection mainly relies on water sensors, which directly trigger an alarm when water ingress is detected.

[0027] However, the current approach of relying on water immersion sensors has the following technical problems:

[0028] 1) The depth of water inflow cannot be accurately determined under the current method;

[0029] 2),Delayed response:,When alarms are only sent through the dashboard, users may,ignore or delay processing;

[0030] 3) Single scenario: No distinction is made between the vehicle's operating status and there is no hierarchical response mechanism;

[0031] 4) No closed-loop service: cannot provide comprehensive services to maintain security.

[0032] Based on the above technical problems, the technical concept of the present invention is as follows: the conductivity of water will significantly change the resistance value between electrodes, and the resistance change is correlated with the water immersion depth. Accordingly, by arranging array electrode sensors on the chassis, when water enters different areas, the current path between the electrodes will produce differentiated resistance data due to the different water coverage area and depth. Since the conductivity of water is much higher than that of air, the real-time collected resistance data can be converted into the corresponding chassis water inlet depth through a pre-calibrated resistance-depth mapping relationship, thereby realizing high-precision, regional water level monitoring.

[0033] The following is about the above technical conception: Figure 1The schematic diagram of the principle of determining the water ingress depth of a vehicle provided by the present invention is shown as follows: Figure 1 As shown, the schematic diagram includes: central processing unit, water immersion sensor, scenario decision-making, vehicle operation status monitoring, cloud platform, response execution terminal, third-party service database, sound and light alarm, mobile phone push, and service linkage.

[0034] In combination with the above embodiments, the technical solution of the present invention is described in detail through specific embodiments. The execution subject of the present invention is a vehicle, for example, Figure 1 The central processing unit in.

[0035] It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0036] Figure 2 FIG1 is a flow chart showing a first embodiment of a method for determining a vehicle water ingress depth according to the present invention, wherein the method is executed by a vehicle. Figure 2 As shown, the method includes the following steps:

[0037] Step 21: When water ingress is detected in the chassis of the vehicle, target resistance data between electrodes collected by an array electrode sensor in the chassis is obtained;

[0038] In this step, water ingress detection can be performed using a water immersion sensor or the like installed on the chassis of the vehicle. For example, when the data detected by the water immersion sensor is compared with a preset threshold or baseline data to determine whether a water ingress event has occurred, the target resistance data between electrodes collected by the array electrode sensor installed in the chassis is obtained.

[0039] Multiple electrodes in the array electrode sensor are distributed at different positions and heights of the chassis. These electrodes will continuously or periodically measure the resistance value between each other. Because water (especially water containing impurities, i.e. rainwater, sewage, river water, seawater, etc. deposited on the road surface) is conductive, it will significantly change the resistance between the electrodes, which can reflect the water ingress.

[0040] That is, as the area of ​​the electrodes immersed in water increases, the cross-sectional area of ​​the current path increases, that is, the resistance between the electrodes decreases.

[0041] For example, if the electrodes of the array electrode sensor are parallel plate electrodes, the smaller the resistance, the greater the immersion depth; if the electrodes of the array electrode sensor are columnar electrodes, the relationship between resistance and immersion depth is nonlinear, and experimental calibration can be performed.

[0042] Optionally, step 21 may include the following implementation:

[0043] Step 1: Obtain first resistance data between electrodes collected by an array electrode sensor in a battery compartment of the chassis, second resistance data between electrodes collected by an array electrode sensor in a motor area of ​​the chassis, and / or third resistance data between electrodes collected by an array electrode sensor in a front compartment area of ​​the chassis;

[0044] In this implementation, array electrode sensors can be set in different areas of the vehicle's chassis, such as the battery compartment, motor area, and front cabin area, to determine the water ingress conditions in different areas.

[0045] Furthermore, resistance data of different regions are obtained.

[0046] Step 2: Determine target resistance data based on the first resistance data, the second resistance data, or / and the third resistance data.

[0047] In this implementation, in order to increase the accuracy of water ingress detection, the resistance data of each area can be combined to determine more accurate target resistance data.

[0048] Exemplarily, in step 2, a possible implementation is: determining the target resistance data according to at least two preset weight coefficients and at least two of the first resistance data, the second resistance data, and the third resistance data.

[0049] In this implementation, different weight coefficients are assigned according to specific conditions of the acquired first resistance data, second resistance data, and third resistance data.

[0050] For example, when only the first resistance data and the second resistance data are collected, since battery safety is higher for new energy vehicles, a higher weight coefficient, such as 60%, can be given to the first resistance data, and correspondingly, 40% can be given to the second resistance data.

[0051] Furthermore, the target resistance data is: first resistance data*60+second resistance data*40%.

[0052] For another example, when the first resistance data, the second resistance data, and the third resistance data are collected, since the safety of the battery is higher for new energy vehicles and the motor is second, a higher weight coefficient, such as 40%, can be given to the first resistance data, 35%, and correspondingly, 25% can be given to the third resistance data.

[0053] Furthermore, the target resistance data is: first resistance data*40+second resistance data*35%+third resistance data*25%.

[0054] It should be understood that: there is no limitation on the configuration of the weight coefficient, which can be determined based on the actual operating status of the vehicle; and in actual usage scenarios, the sum of the weight coefficients used is 1.

[0055] Step 22: Determine the target water ingress depth of the chassis based on the target resistance data.

[0056] In this step, after the target resistance data is obtained, the target water inflow depth of the chassis is determined based on the resistance change between the electrodes indicated by the target resistance data.

[0057] Optionally, step 22 may include: determining a target water inflow depth corresponding to the target resistance data in a relationship curve, where the relationship curve is used to indicate a corresponding relationship between resistance and water inflow depth.

[0058] In this implementation, the electrodes of the array electrode sensor in the vehicle can actually be set upward from the bottom of the chassis. The more the electrodes are submerged, the smaller the resistance between the electrodes. Therefore, the relationship curve of the water ingress depth corresponding to different resistances between the electrodes can be pre-calibrated by experimental methods.

[0059] Furthermore, when the target resistance data is obtained, the water inflow depth corresponding to the target resistance data can be read from the relationship curve and recorded as the target water inflow depth.

[0060] It should be understood that the conductivity of different water qualities may vary. At this time, the vehicle's visual sensors can also be used to detect the type of water in the environment, such as river water, rainwater, sewage, etc., and determine different relationship curves respectively. The target water inlet depth can be determined based on the relationship curve corresponding to the target resistance data and the type of water in which the vehicle is located.

[0061] The above relationship curve can be obtained from a third-party service database based on the cloud platform, or obtained from the cloud platform after being determined by R&D personnel.

[0062] The method for determining the depth of water ingress into a vehicle provided by an embodiment of the present invention obtains target resistance data between electrodes collected by an array of electrode sensors in the vehicle chassis upon detecting water ingress. Based on this target resistance data, the target water ingress depth of the chassis can be determined. This technical solution monitors the resistance data between the electrodes in the chassis in real time and, utilizing the correlation between the conductive properties of water and the water level, maps the target resistance data into a precise water ingress depth value. This enables rapid response and high-precision detection of water ingress into the chassis, providing real-time data support for vehicle water safety protection, effectively avoiding safety hazards such as electrical short circuits and battery damage caused by water ingress, and significantly improving the safety and reliability of vehicles in complex road conditions.

[0063] Based on the above embodiments, Figure 3 FIG2 shows a flow chart of a second embodiment of a method for determining a vehicle water ingress depth provided by the present invention, the method being executed by a vehicle. Figure 3 As shown, the method may further include the following steps:

[0064] Step 31: Determine a target mapping relationship corresponding to a target operating state of the vehicle from the mapping relationships corresponding to at least one operating state;

[0065] Each mapping relationship records a correspondence between at least one water ingress range and at least one response strategy under a corresponding operating state. The at least one response strategy is a strategy for controlling the vehicle to execute a user alert, risk avoidance guidance, or / and protection of vehicle components (e.g., battery, motor, etc.);

[0066] In this step, since a response strategy of a target water inflow depth corresponding to different operating states of the vehicle can be adopted, the current operating state of the vehicle is first determined and recorded as the target operating state.

[0067] For example, the operating state may include: driving state, parking state, and leaving state.

[0068] Furthermore, after the target operating state is determined, a mapping relationship corresponding to the target operating state is determined and recorded as a target mapping relationship.

[0069] Taking the driving state as the target operating state as an example, the correspondence between at least one water inflow range corresponding to the driving state and at least one response strategy is used as the target mapping relationship.

[0070] In addition, different water inlet ranges can also set corresponding water inlet levels. Different water inlet levels correspond to different response strategies. In actual implementation, the principles are similar and must be implemented based on the water inlet range.

[0071] Optionally, the mapping relationship corresponding to at least one operating state includes at least one of the following:

[0072] 1) If the operating state is driving and the water ingress range is less than the first value, the response strategy is: the water ingress icon on the instrument panel lights up and a voice prompt is given indicating that the chassis is flooded;

[0073] In this implementation, if the water ingress range is less than the first value, it is considered that the water ingress into the vehicle is not serious. When the operating state is the driving state, it is necessary to gently remind the user through the devices in the vehicle, that is, the water ingress icon on the dashboard lights up and a voice is played, such as: water immersion is detected in the chassis.

[0074] For example, the first value may be 3 cm.

[0075] 2) If the operating state is driving and the water ingress range is equal to or greater than the first value, the response strategy is: the ambient light flashes a preset color, an alarm sound is broadcast, and a risk avoidance guidance message is displayed in the central control console;

[0076] In this implementation, if the water ingress range is equal to or greater than the first value, it is considered that the vehicle has serious water ingress. When the operating state is driving, it is necessary to use the devices in the vehicle to remind the user, that is, the ambient light flashes red, broadcasts the alarm voice, and pops up risk avoidance guidance information on the central console, such as: whether it is necessary to navigate to a nearby repair station.

[0077] Among them, information about nearby repair stations, designated repair stations for vehicle insurance, etc. can be obtained from a third-party service database based on the cloud platform.

[0078] 3) If the vehicle is in parking state and the water ingress range is any value, the response strategy is: broadcast a warning sound and push an alarm message to the vehicle owner's terminal;

[0079] In this implementation, if the vehicle is in a parked state and the water inflow range is any value, it is considered that the vehicle has stopped. If the water inflow rises or in this case, to ensure the safety of the user, it is necessary to broadcast a warning sound, such as: a looping warning sound from the vehicle horn; and push an alarm message to the owner's terminal to prompt him to check the vehicle status in time, such as: pushing an alarm message to the owner's mobile phone.

[0080] 4) If the running state is the off-vehicle state and the water inflow range is equal to or greater than the first value, the response strategy is: closing the battery valve, broadcasting a warning sound, and pushing an alarm message to the vehicle owner's terminal.

[0081] In this implementation, if the operating state is the off-vehicle state and the water inflow range is equal to or greater than the first value, it is considered that the user is not in the vehicle. When the water depth is too high, the vehicle will be damaged. At this time, the battery valve can be closed to prevent the circuit from being broken due to water inflow; a warning sound is broadcast, such as: a looping warning sound of the vehicle horn; and an alarm message is pushed to the owner's terminal to prompt the owner to check the vehicle status in time, such as: pushing an alarm message to the owner's mobile phone.

[0082] In addition, after the user confirms the alarm, a water ingress report can be generated based on the time of water ingress, target water ingress depth, vehicle positioning, etc.; and then pushed to the bound insurance company, repair shop, etc.

[0083] It should be understood that in actual implementation, the water inlet range can be further refined, and other values ​​can be set above or below the first value in addition to the first value. The principle is similar and will not be repeated here.

[0084] Step 32: Determine a target response strategy corresponding to the target water inflow depth in the target mapping relationship;

[0085] In this step, after determining the target mapping relationship corresponding to the target operating state, the water inflow range in the target mapping relationship is selected according to the target water inflow depth, and the response strategy corresponding to the corresponding water inflow range is determined as the target response strategy.

[0086] In a possible implementation, taking the driving state as the target operating state as an example, when the target water inflow depth is determined to be 3.1 cm, the target response strategy is determined to be 2) in the embodiment of the above step 31.

[0087] Step 33: Control the vehicle to execute the target response strategy.

[0088] In this step, according to the target response strategy, relevant devices in the vehicle are controlled to execute the implementation of the target response strategy.

[0089] In one possible implementation, taking the target response strategy as 2) in the embodiment of the above step 31 as an example, the ambient light in the vehicle is controlled to be red and flashing, the audio unit is controlled to play an alarm sound, and the central control of the vehicle is controlled to pop up hazard avoidance guidance information, such as: whether it is necessary to navigate to a nearby repair station.

[0090] The method for determining the depth of water ingress into a vehicle provided by an embodiment of the present invention determines a target mapping relationship corresponding to the target operating state of the vehicle in a mapping relationship corresponding to at least one operating state; each mapping relationship records a corresponding relationship between at least one water ingress range and at least one response strategy in the corresponding operating state, and at least one response strategy is used to control the vehicle to execute a strategy of reminding the user, guiding risk avoidance, or / and protecting vehicle components; determines a target response strategy corresponding to the target water ingress depth in the target mapping relationship; and controls the vehicle to execute the target response strategy. In this solution, a preset mapping relationship is automatically matched according to the real-time operating state of the vehicle, and then combined with high-precision water ingress depth detection, a differentiated response strategy is triggered, thereby avoiding excessive intervention while ensuring safety. At the same time, the system response speed and decision accuracy are significantly improved through the predefined strategy library, so as to achieve a fully automatic water wading protection effect that takes into account real-time, reliability, and scenario adaptability.

[0091] Based on the above embodiments, Figure 4 FIG. 3 is a flow chart showing a third embodiment of a method for determining a vehicle water ingress depth according to the present invention, the method being executed by a vehicle. Figure 4 As shown, step 21 may include the following steps:

[0092] Step 41: Obtain vehicle navigation information and / or vehicle weather information;

[0093] In this step, in order to improve the accuracy of the target resistance data, the vehicle's navigation information can be obtained. Since the navigation information contains the road conditions, slope, etc. of the path, this has a certain impact on water ingress; the vehicle's weather information can also be obtained. When it rains, the vehicle is more likely to ingress water and rainwater is more likely to accumulate on the road surface.

[0094] Optionally, weather information can be obtained from a cloud platform based on the vehicle's location.

[0095] Step 42: If the navigation information indicates that the road ahead is a wading section or a sloped section, and / or the weather information indicates that the current weather is rainy, target resistance data between electrodes collected by the array electrode sensor in the chassis is obtained at a first preset frequency.

[0096] In this step, when the navigation information indicates that the road ahead is a wading section or a slope section, and / or the weather information indicates that the current weather is rainy, since the vehicle's chassis is more likely to be infiltrated with water, at this time, the frequency of obtaining the target resistance data should be increased, that is, obtained at the first preset frequency.

[0097] The first preset frequency is greater than the acquisition frequency of the vehicle under normal circumstances.

[0098] The method for determining the depth of water ingress into a vehicle provided by an embodiment of the present invention obtains the vehicle's navigation information and / or the vehicle's weather information; if the navigation information indicates that the road ahead is a flooded section or a sloped section, and / or the weather information indicates that the current weather is rainy, the target resistance data between electrodes collected by the array electrode sensor in the chassis is obtained at a first preset frequency. This solution dynamically adjusts the detection frequency of the electrode sensor by combining navigation prediction with real-time weather data, achieving proactive prevention and control of water ingress risks. That is, when the navigation indicates a flooded section or steep slope ahead, or when the weather system detects rainfall, it automatically switches to the first preset frequency, capturing the risk of water ingress into the chassis in advance and enhancing monitoring sensitivity. This ensures the real-time nature of water ingress detection under complex environmental changes, while optimizing system energy consumption and data processing load through intelligent frequency adjustment, ultimately achieving a balance between risk warning and resource efficiency.

[0099] Figure 5 FIG. 1 is a schematic diagram showing the structure of an embodiment of a device for determining the depth of water ingress into a vehicle provided by the present invention. Figure 5 As shown, the device includes:
