Technical Field

[0001] This invention relates to the field of vehicle safety technology, and in particular to a method, apparatus, equipment and storage medium for detecting vehicle water leaks. Background Technology

[0002] Vehicles parked outdoors (such as on the roadside or in outdoor parking lots) may experience water leaks after the owner leaves. These leaks can be caused by factors such as vehicle design flaws, long-term parking under trees leading to clogged drainage pipes, windshield damage from falling objects during typhoons, aging drainage pipes causing localized leaks, or regional flooding such as localized flooding. Owners may not be aware of these leaks in time. In particular, if the vehicle is not used for an extended period, the driver's compartment may even become flooded, leading to vehicle damage and financial losses.

[0003] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is prior art. Summary of the Invention

[0004] The main objective of this invention is to provide a method, apparatus, device, and storage medium for detecting vehicle water leaks, aiming to solve the technical problem that existing technologies cannot detect vehicle water leaks in a timely manner.

[0019] Optionally, before the step of obtaining the vehicle's location information and the humidity inside and outside the vehicle when the vehicle meets the leakage detection conditions, the method further includes:

[0020] Obtain the instantaneous rainfall in the area where the vehicle is located;

[0021] When the instantaneous rainfall exceeds a preset rainfall threshold and the vehicle is unoccupied, the remaining energy of the vehicle is obtained.

[0022] If the remaining energy is greater than a preset reserve threshold, then it is detected whether the vehicle is in an outdoor environment;

[0023] If the vehicle is in an outdoor environment, then the vehicle is determined to meet the leakage detection conditions.

[0024] Optionally, the step of detecting whether the vehicle is leaking water based on the leak detection value, the first humidity determination value, and the second humidity determination value includes:

[0025] The third determination value is determined based on the first humidity determination value and the preset correction coefficient;

[0026] If the water leakage detection value is less than or equal to the second humidity determination value, then the vehicle is determined not to leak water.

[0027] If the water leakage detection value is greater than the second humidity determination value and less than the first humidity determination value, then the vehicle is determined to be leaking water, and the degree of leakage indicates that there is a risk of leakage.

[0028] If the water leakage detection value is greater than the first humidity determination value and less than the third determination value, then the vehicle is determined to be leaking water, and the degree of leakage is minor.

[0029] If the water leakage detection value is greater than or equal to the third determination value, then the vehicle is determined to be leaking water, and the degree of leakage is severe.

[0030] Optionally, after the step of detecting whether the vehicle is leaking based on the leakage detection value, the first humidity determination value, and the second humidity determination value, the method further includes:

[0031] Obtain the leak detection results;

[0032] If the water leakage detection result indicates that the vehicle is leaking, then the degree of water leakage of the vehicle is obtained;

[0043] In addition, to achieve the above objectives, the present invention also proposes a vehicle water leakage detection device, which includes: a processor, a memory, and a vehicle water leakage detection program stored in the memory and executable on the processor. When the vehicle water leakage detection program is executed, it implements the steps of the vehicle water leakage detection method as described above.

[0044] Furthermore, to achieve the above objectives, the present invention also proposes a computer-readable storage medium storing a vehicle water leakage detection program, which, when executed, implements the steps of the vehicle water leakage detection method as described above.

[0045] This invention acquires the vehicle's location information and the humidity levels inside and outside the vehicle when the vehicle meets the leakage detection conditions; it then locates the corresponding first and second humidity judgment values ​​based on the location information; calculates the leakage detection value based on the humidity levels inside and outside the vehicle; and finally detects whether the vehicle is leaking based on the leakage detection value, the first humidity judgment value, and the second humidity judgment value. Because the leakage detection value is calculated based on the humidity levels inside and outside the vehicle, and compared with the first and second humidity judgment values ​​located based on the location information, the difference between the humidity levels inside and outside the vehicle can be determined based on the comparison result, thus quickly determining whether the vehicle is leaking.

[0051] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0052] Reference Figure 1 , Figure 1 This is a schematic diagram of the vehicle water leakage detection device structure in the hardware operating environment involved in the embodiments of the present invention.

[0053] like Figure 1As shown, the electronic device may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005.

The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory 1005 may be high-speed random access memory (RAM) or stable non-volatile memory (NVM), such as a disk drive. The memory 1005 may also optionally be a storage device independent of the aforementioned processor 1001.

[0054] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the electronic device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0055] like Figure 1 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and a vehicle water leakage detection program.

[0056] exist Figure 1 In the electronic device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the electronic device of the present invention can be set in the vehicle water leakage detection device. The electronic device calls the vehicle water leakage detection program stored in the memory 1005 through the processor 1001 and executes the vehicle water leakage detection method provided in the embodiment of the present invention.

[0057] This invention provides a method for detecting vehicle water leaks, referring to... Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of a vehicle water leakage detection method according to the present invention.

[0058] In this embodiment, the vehicle water leakage detection method includes the following steps:

[0059] Step S10: When the vehicle meets the leakage detection conditions, obtain the vehicle's location information and the humidity inside and outside the vehicle.

[0060] It should be noted that the executing entity in this embodiment can be the vehicle water leakage detection device, which can be a personal computer or a server. The vehicle water leakage detection device is equipped with a system that can remotely control the vehicle. Of course, the executing entity in this embodiment can also be other devices that can achieve the same or similar functions. This embodiment does not limit this. In this embodiment, the vehicle water leakage detection method of the present invention is described using a vehicle water leakage detection device as an example.

[0061] It should be noted that the leak detection conditions can be pre-set by the personnel managing the vehicle leak detection equipment. If a vehicle meets the leak detection conditions, it indicates that a leak detection test is needed to determine if the vehicle is leaking. To facilitate leak detection, the vehicle's location information and the humidity levels inside and outside the vehicle can be obtained. The humidity levels inside and outside the vehicle can include the humidity value inside the vehicle and the humidity value of the area where the vehicle is located.

[0062] In practical implementation, the vehicle leak detection device can remotely wake up the vehicle's GPS positioning module to obtain the vehicle's location information, thus determining the vehicle's current location. Alternatively, it can obtain the vehicle's parking location information from the cloud or a mobile terminal and use that as the vehicle's current location. After obtaining the vehicle's location information, the device can retrieve the corresponding weather information from a weather monitoring application. Based on the weather information, it determines the vehicle's ambient humidity value and then wakes up the vehicle's internal humidity sensor to collect the ambient humidity value inside the vehicle, thereby obtaining the vehicle's internal and external humidity levels. The weather monitoring application can be software provided by a weather monitoring agency or a third-party organization. The humidity sensor can be a unit-installed sensor or a sensor integrated into other vehicle components, such as a sensor integrated into the vehicle's air conditioning system.

[0063] In practical implementation, vehicles will only leak water on rainy days, especially when the rainfall is heavy. Therefore, it is possible to first check whether it is raining in the area where the vehicle is located, and whether the rainfall exceeds a certain amount. If so, it can be determined that the vehicle meets the leakage detection conditions. In this case, before step S10 described in this embodiment, the following steps may also be included:

[0064] Obtain the instantaneous rainfall in the area where the vehicle is located;

[0065] If the instantaneous rainfall exceeds a preset rainfall threshold, the vehicle is determined to meet the leakage detection conditions.

[0066] It should be noted that the vehicle's location area can be determined based on the last location information uploaded by the vehicle before parking. For example, when the owner locks the vehicle, the vehicle system uploads the vehicle's location information to the vehicle leak detection device before entering sleep mode. The instantaneous rainfall in the vehicle's location area can be obtained from weather information in the area provided by a weather monitoring application, and the instantaneous rainfall can be extracted from that information. The preset rainfall threshold can be pre-set by the vehicle leak detection device administrator according to actual needs, for example, setting the preset rainfall threshold to 10 nm / 24 hours.

[0067] Furthermore, if there are people in the vehicle, performing a leak detection at this time would affect the user's use of the vehicle. Also, if there are people in the vehicle, even if a leak occurs, the driver or passengers can respond promptly, so a leak detection is not actually necessary. Therefore, when the instantaneous rainfall exceeds a preset rainfall threshold, it is possible to detect whether there are people in the vehicle. Only if no one is present should a leak detection be performed. In this case, the step described in this embodiment of determining that the vehicle meets the leak detection conditions when the instantaneous rainfall exceeds the preset rainfall threshold can include:

[0068] If the instantaneous rainfall exceeds a preset rainfall threshold and there is no one in the vehicle, the vehicle is determined to meet the conditions for vehicle leakage.

[0069] It's important to note that determining whether someone is inside a vehicle can be done by checking if the vehicle is in lock / sleep mode (i.e., the vehicle's systems are in sleep mode and the doors are locked). If the vehicle is in lock / sleep mode, it means the vehicle is currently parked and the driver is not nearby; in this case, it can be determined that no one is inside. Alternatively, it can be determined by activating the vehicle's wireless module and checking if the car key's signal can be detected. If the car key's signal cannot be detected, it can be determined that no one is inside.

[0070] Furthermore, since collecting the relevant data required for each leak detection necessitates activating certain modules in the vehicle to assist in data collection, insufficient vehicle power may render the vehicle unusable for the owner. Moreover, if the vehicle is a new energy vehicle, it may even experience a power outage. To avoid this drawback, the step described in this embodiment of determining that the vehicle meets the conditions for a leak when the instantaneous rainfall exceeds a preset rainfall threshold and no one is inside the vehicle may include:

[0071] When the instantaneous rainfall exceeds a preset rainfall threshold and the vehicle is unoccupied, the remaining energy of the vehicle is obtained.

[0072] If the remaining energy is greater than a preset reserve threshold, the vehicle is determined to meet the leakage detection conditions.

[0073] It should be noted that different indicators can be collected as the remaining energy level depending on the type of vehicle. For example, if the vehicle uses gasoline, the remaining fuel level can be collected as the remaining energy level; if the vehicle is a new energy vehicle, the remaining electricity level can be collected as the remaining energy level. The preset reserve threshold can be pre-set by the administrator of the vehicle leak detection equipment according to actual needs, for example, setting the preset reserve threshold to 20%. Different preset reserve thresholds can be set for vehicles using different energy sources.

[0074] Understandably, if the vehicle's remaining energy is greater than the preset threshold, it indicates that the vehicle has ample remaining energy, and detection can proceed normally. However, since new energy vehicles do not experience depletion of power even when charging, even with low battery levels, it's possible to determine if the vehicle is a new energy vehicle before acquiring its remaining energy. If it is a new energy vehicle and is currently charging, then acquiring the remaining energy is unnecessary; the vehicle can be directly deemed to meet the leak detection criteria.

[0075] Furthermore, since vehicles parked indoors are generally not affected by factors such as rain, leak detection is unnecessary. To avoid unnecessary testing, the step described in this embodiment, which determines that the vehicle meets the leak detection conditions if the remaining energy level is greater than a preset reserve threshold, may include:

[0076] If the remaining energy is greater than a preset reserve threshold, then it is detected whether the vehicle is in an outdoor environment;

[0077] If the vehicle is in an outdoor environment, then the vehicle is determined to meet the leakage detection conditions.

[0078] It should be noted that if the vehicle is detected to be in an outdoor environment, it indicates that the vehicle is parked outdoors and may be leaking, requiring a leak detection test. In this case, the vehicle can be determined to meet the leak detection criteria. Specifically, to detect whether the vehicle is in an outdoor environment, the vehicle's onboard communication module (GPS module) can be activated to check if GPS satellite signals can be detected. If not, the vehicle is determined to be in an indoor environment; if so, it is determined to be in an outdoor environment.

[0079] Furthermore, in order to accurately determine whether the vehicle is truly outdoors and affected by rainfall, after determining that the vehicle is in an outdoor environment, the vehicle leakage detection equipment can also activate the rain sensor installed on the vehicle. The rain sensor will detect whether rainfall is detected. Only if rainfall is detected will the vehicle be deemed to meet the leakage detection conditions.

[0080] Step S20: Find the corresponding first humidity determination value and second humidity determination value based on the location information.

[0081] It should be noted that finding the corresponding first and second humidity judgment values ​​based on location information can be achieved by matching the location information with a preset area to determine the vehicle's region, and then searching for the corresponding first and second humidity judgment values ​​in the leak calibration database. The leak calibration database can be a database storing first and second humidity judgment values ​​for different regions to determine whether a vehicle has a leak. The leak calibration database can be pre-set by the administrator of the vehicle leak detection equipment. It can be located locally on the vehicle leak detection equipment or on a remote server; this embodiment does not impose any restrictions. The preset area can be pre-divided according to streets, towns, districts, counties, provinces, cities, or tropical regions, etc.

[0082] Step S30: Calculate the leakage detection value based on the humidity inside and outside the vehicle.

[0083] It should be noted that calculating the leak detection value based on the humidity inside and outside the vehicle can be done by reading the humidity value inside the vehicle and the humidity value of the region where the vehicle is located, then subtracting the humidity value of the region where the vehicle is located from the humidity value inside the vehicle, and using the difference as the leak detection value.

[0084] Step S40: Detect whether the vehicle is leaking water based on the leak detection value, the first humidity determination value, and the second humidity determination value.

[0085] It should be noted that detecting whether a vehicle is leaking water based on the leak detection value, the first humidity judgment value, and the second humidity judgment value can be achieved by comparing the leak detection value with the first humidity judgment value and the second humidity judgment value to determine whether the vehicle is leaking water and to determine the severity of the leak.

[0086] Furthermore, in order to quickly determine whether the vehicle is leaking water and to determine the severity of the leak, step S40 of this embodiment may include:

[0087] The third determination value is determined based on the first humidity determination value and the preset correction coefficient;

[0088] If the water leakage detection value is less than or equal to the second humidity determination value, then the vehicle is determined not to leak water.

[0089] If the water leakage detection value is greater than the second humidity determination value and less than the first humidity determination value, then the vehicle is determined to be leaking water, and the degree of leakage indicates that there is a risk of leakage.

[0090] If the water leakage detection value is greater than the first humidity determination value and less than the third determination value, then the vehicle is determined to be leaking water, and the degree of leakage is minor.

[0091] If the water leakage detection value is greater than or equal to the third determination value, then the vehicle is determined to be leaking water, and the degree of leakage is severe.

[0092] It should be noted that the preset correction factor is greater than 1. The preset correction factor can be set in advance by the administrator of the vehicle leak detection equipment, for example, setting the preset correction factor to 1.2. Determining the third judgment value based on the first humidity judgment value and the preset correction factor can be done by multiplying the first humidity judgment value by the preset correction factor and using the product as the third judgment value.

[0093] In practice, if the water leakage detection value is less than or equal to the second humidity judgment value, it means that the humidity difference between the inside and outside of the vehicle is very small. At this time, the relative humidity inside the vehicle is normal. Therefore, it can be determined that the vehicle is not leaking water.

[0094] If the water leakage detection value is greater than the second humidity judgment value but less than the first humidity judgment value, it means that the difference between the humidity inside and outside the vehicle is normal and the difference value is still within the normal range. However, the vehicle may already have a water leakage. In order to ensure that the car owner pays attention, it can be determined that the vehicle has a water leakage, but the degree of water leakage is a water leakage risk.

[0095] If the water leakage detection value is greater than the first humidity judgment value but less than the third judgment value, it means that there is a large difference in humidity between the inside and outside of the vehicle, and the difference value has exceeded the normal range. However, the amount of the difference is not extremely large. That is, the vehicle is leaking water, but the degree of leakage is not extremely large. At this time, it can be determined that the vehicle is leaking water, and the degree of leakage is minor.

[0096] If the water leakage detection value is greater than the third judgment value, it means that the humidity difference between the inside and outside of the vehicle is extremely large and has exceeded the normal range. At this time, the vehicle may have a serious water leakage, or even be submerged in water. In this case, it can be determined that the vehicle has a water leakage and the degree of leakage is a serious water leakage.

[0097] In a specific implementation, to minimize the loss to the car owner, after step S40 in this embodiment, the following may also be included:

[0098] Obtain the leak detection results;

[0099] If the water leakage detection result indicates that the vehicle is leaking, then the degree of water leakage of the vehicle is obtained;

[0100] Obtain the corresponding handling strategy for the degree of leakage;

[0101] The vehicle is controlled according to the aforementioned handling strategy to prevent damage to the vehicle.

[0102] It should be noted that obtaining the corresponding handling strategy for the degree of leakage can be done by searching for the corresponding handling strategy in a handling strategy library based on the degree of leakage. This handling strategy library can include handling strategies for different degrees of leakage, and different degrees of leakage require different handling strategies. The handling strategy library can be pre-configured by the administrators of the vehicle leakage detection equipment.

[0103] For example, the handling strategy for a water leakage level of "there is a risk of water leakage" is set as follows: obtain the car owner's reserved communication method (SMS, email or communication software, etc.), notify the car owner to park the vehicle properly according to the reserved communication method to avoid water leakage, and re-inspect the vehicle for water leakage at regular intervals (such as ten minutes).

[0104] The handling strategy for minor water leakage is set as follows: obtain the owner's reserved communication method, notify the owner that the vehicle has leaked water through the reserved communication method, and shut down the electronic components in the vehicle after the notification to avoid vehicle damage (if the vehicle is a new energy vehicle, it can also detect whether the vehicle is charging, and if so, stop charging).

[0105] The handling strategy for severe water leakage is set as follows: execute the handling strategy for minor water leakage, and additionally obtain the water leakage detection results of other vehicles to determine whether there are other vehicles with severe water leakage in the same area and road section as this vehicle (such as in the same open-air parking lot or the same low-lying road section). If so, the information is reported to the traffic management department to remind them to conduct on-site public disaster investigation.

[0106] Of course, in actual use, for vehicles that do not leak according to the leak detection result, a leak detection can be performed again after a certain period of time (such as ten minutes) to ensure that vehicles with leaks are detected in a timely manner.

[0107] This embodiment acquires the vehicle's location information and the humidity inside and outside the vehicle when the vehicle meets the leakage detection conditions; it then finds the corresponding first and second humidity judgment values ​​based on the location information; calculates the leakage detection value based on the humidity inside and outside the vehicle; and detects whether the vehicle is leaking based on the leakage detection value, the first humidity judgment value, and the second humidity judgment value. Since the leakage detection value is calculated based on the humidity inside and outside the vehicle and compared with the first and second humidity judgment values ​​found based on the location information, the comparison result indicates whether the difference between the humidity inside and outside the vehicle is within the normal range, thus quickly determining whether the vehicle is leaking.

[0108] refer to Figure 3 , Figure 3 This is a flowchart illustrating a second embodiment of a vehicle water leakage detection method according to the present invention.

[0109] Based on the first embodiment described above, the vehicle water leakage detection method of this embodiment further includes, before step S10:

[0110] Step S01: Collect the location information and the humidity inside and outside the vehicle corresponding to the vehicle that meets the preset humidity collection conditions.

[0111] It should be noted that vehicles that meet the preset humidity collection conditions can be those that meet the leakage detection conditions and have been determined to have no risk of leakage. The determination of whether a vehicle has a risk of leakage can be confirmed by the vehicle owner and uploaded, or it can be confirmed manually by the management personnel of the vehicle leakage detection equipment (such as by calling the monitoring equipment around the vehicle for confirmation).

[0112] In practice, the vehicle leak detection device can remotely wake up the GPS positioning module in the vehicle and obtain the vehicle's location information through the GPS positioning module.

[0113] In its implementation, after acquiring the vehicle's location information, the vehicle leak detection equipment can obtain the corresponding weather information from a weather monitoring application. Based on the weather information, it determines the vehicle's ambient humidity value and then activates the vehicle's internal humidity sensor to collect the ambient humidity value inside the vehicle, thereby obtaining the humidity inside and outside the vehicle. The weather monitoring application can be software provided by a weather monitoring agency or by a third-party organization.

[0114] Furthermore, to ensure the accuracy of the collected humidity, step S01 in this embodiment may include:

[0115] Vehicles that meet the preset humidity collection conditions will be selected as target vehicles;

[0116] Turn on the vehicle's air conditioning and control it to operate in warm air recirculation mode;

[0117] When the vehicle air conditioner runs continuously in warm air recirculation mode for a preset duration, the location information of the target vehicle and the humidity inside and outside the vehicle are collected.

[0118] It should be noted that since the moisture inside the vehicle may not have completely evaporated into the air, and because the humidity sensors are installed in different locations inside the vehicle, directly collecting the humidity inside the vehicle may lead to inaccurate results. To avoid this, after selecting the target vehicle (i.e., the vehicle being collected from), you can remotely control the vehicle's air conditioning to turn on and run it in warm air recirculation mode to allow the moisture inside the vehicle to fully evaporate into the air. When the air conditioning is running in warm air mode for a preset time, it can be determined that the moisture inside the vehicle has fully evaporated. At this time, you can collect the location information of the target vehicle and the humidity inside and outside the vehicle.

[0119] The preset duration can be set in advance by the administrator of the vehicle leak detection equipment, for example, the preset duration can be set to 5 minutes.

[0120] In practice, to avoid affecting the normal use of the vehicle by the owner, if the owner remotely controls or unlocks the vehicle during the process of detecting whether the vehicle meets the preset humidity collection conditions or controlling the vehicle air conditioner to operate in the warm air recirculation mode, the step of collecting location information and humidity inside and outside the vehicle can be terminated until the next time the owner controls the vehicle to enter the lock sleep mode, then the vehicle will be checked again to see if it meets the preset humidity collection conditions. If it does, then the above step S01 will be executed.

[0121] Step S02: Calculate the humidity difference value based on the humidity inside and outside the vehicle.

[0122] In practice, calculating the humidity difference value based on the humidity inside and outside the vehicle can be done by reading the humidity value inside the vehicle and the humidity value of the region where the vehicle is located, then subtracting the humidity value of the region where the vehicle is located from the humidity value inside the vehicle, and using the difference as the humidity difference value.

[0123] Step S03: Classify the humidity difference values ​​based on the location information to obtain multiple difference datasets.

[0124] It should be noted that classifying humidity difference values ​​based on location information to obtain multiple difference datasets can be achieved by storing humidity difference values ​​corresponding to the same location information in the same set, so that each region belongs to a different difference dataset, thus obtaining multiple difference datasets. Here, "the same location information" refers to location information belonging to the same region.

[0125] Step S04: Determine the first humidity determination value and the second humidity determination value corresponding to different location information based on the multiple difference datasets.

[0126] It should be noted that determining the first and second humidity judgment values ​​corresponding to different location information based on multiple difference datasets can be done by taking the difference dataset corresponding to any location information as the target difference dataset, calculating the average and maximum values ​​of each humidity difference value in the target difference dataset, taking the maximum value as the first humidity judgment value corresponding to the combination, and taking the average value as the second humidity judgment value corresponding to the combination.

[0127] Understandably, to facilitate subsequent queries and prevent data loss, the first and second humidity determination values ​​corresponding to different location information can be stored in the leakage calibration database.

[0128] For example: Suppose a location information A, the corresponding difference dataset contains data {B1(T X B2(T) X )).......B n (T X )};

[0129] The calculated average is B. ave (T X The maximum value is B. max (T X If the location information (location information A) is such that the first humidity determination value is B, then the first humidity determination value corresponding to this location information (location information A) is B. max (T X The second humidity judgment value is B. ave (T X ).

[0130] In order to ensure the accuracy of the judgment based on the judgment value, when collecting data, it is necessary to ensure that the number of data in each difference dataset reaches a preset number (such as setting the preset number to 100).

[0131] In practical applications, since ambient temperature can also affect humidity, when classifying humidity differences, the ambient temperature of the vehicle's location can also be obtained. Humidity differences can be classified based on both ambient temperature and location information, allowing different combinations of location information and ambient temperature values ​​to correspond to different first and second humidity judgment values. Therefore, when detecting leaks in a vehicle, the corresponding first and second humidity judgment values ​​can be found based on the vehicle's location and ambient temperature.

[0132] Furthermore, to avoid the influence of vehicle model information on the leak detection results, step S20 in this embodiment may include:

[0133] Obtain the vehicle model information of the vehicle;

[0134] Based on the vehicle model information and the location information, find the corresponding first humidity determination value and second humidity determination value.

[0135] It should be noted that different vehicle models may have different levels of airtightness and interior space, and the methods for determining whether a vehicle is leaking may also differ. To avoid the impact of vehicle model on the accuracy of vehicle leak detection, when classifying humidity difference values, the vehicle model information of each vehicle can also be used for classification, so that different vehicle model information and different location information can correspond to different first humidity judgment values ​​and second humidity judgment values.

[0136] Understandably, since vehicle model information was also included in the classification of humidity difference values, the vehicle model information was also included in the search when obtaining the first and second humidity judgment values ​​for leak detection. This ensures that the obtained judgment values ​​and the vehicle to be tested are calculated based on data collected from vehicles of the same model, thereby avoiding the influence of vehicle model on vehicle leak detection.

[0137] This embodiment collects location information and internal and external humidity of vehicles that meet preset humidity collection conditions; calculates humidity difference values ​​based on the internal and external humidity; classifies the humidity difference values ​​based on the location information to obtain multiple difference datasets; and determines a first humidity judgment value and a second humidity judgment value corresponding to different location information based on the multiple difference datasets. Because data from vehicles meeting the conditions is collected in advance, and the calculated humidity difference values ​​are classified according to the vehicle's location information, and then the first and second humidity judgment values ​​corresponding to different location information and different environments are calculated after classification, it ensures that when vehicle inspection is required, the first and second humidity judgment values ​​needed for leak detection can be quickly obtained, providing a foundation for vehicle leak detection.

[0138] Furthermore, this embodiment of the invention also proposes a storage medium storing a vehicle water leakage detection program, which, when executed by a processor, implements the steps of the vehicle water leakage detection method described above.

[0139] Reference Figure 4 , Figure 4 This is a structural block diagram of the first embodiment of the vehicle water leakage detection device of the present invention.

[0140] like Figure 4 As shown, the vehicle water leakage detection device proposed in this embodiment of the invention includes:

[0141] The information acquisition module 10 is used to acquire the vehicle's location information and the humidity inside and outside the vehicle when the vehicle meets the water leakage detection conditions.

[0142] The data lookup module 20 is used to look up the corresponding first humidity determination value and second humidity determination value based on the location information;

[0143] The numerical calculation module 30 is used to calculate the leakage detection value based on the humidity inside and outside the vehicle;

[0144] The water leakage detection module 40 is used to detect whether the vehicle is leaking water based on the water leakage detection value, the first humidity determination value and the second humidity determination value.

[0145] This embodiment acquires the vehicle's location information and the humidity inside and outside the vehicle when the vehicle meets the leakage detection conditions; it then finds the corresponding first and second humidity judgment values ​​based on the location information; calculates the leakage detection value based on the humidity inside and outside the vehicle; and detects whether the vehicle is leaking based on the leakage detection value, the first humidity judgment value, and the second humidity judgment value. Since the leakage detection value is calculated based on the humidity inside and outside the vehicle, and compared with the first and second humidity judgment values ​​found based on the location information, the comparison result indicates whether the difference between the humidity inside and outside the vehicle is within a normal range, thus quickly determining whether the vehicle is leaking.

[0146] Furthermore, the information acquisition module 10 is also used to collect the location information and the humidity inside and outside the vehicle corresponding to the vehicle that meets the preset humidity collection conditions; calculate the humidity difference value based on the humidity inside and outside the vehicle; classify the humidity difference value based on the location information to obtain multiple difference datasets; and determine the first humidity judgment value and the second humidity judgment value corresponding to different location information based on the multiple difference datasets.

[0147] Furthermore, the information acquisition module 10 is also used to select vehicles that meet the preset humidity collection conditions as target vehicles; turn on the vehicle air conditioner of the target vehicle and control the vehicle air conditioner to operate in the warm air recirculation mode; when the vehicle air conditioner operates in the warm air recirculation mode for a preset duration, collect the location information corresponding to the target vehicle and the humidity inside and outside the vehicle.

[0148] Furthermore, the information acquisition module 10 is also used to acquire the instantaneous rainfall in the area where the vehicle is located; when the instantaneous rainfall is greater than a preset rainfall threshold and there is no one in the vehicle, acquire the remaining energy of the vehicle; if the remaining energy is greater than a preset reserve threshold, detect whether the vehicle is in an outdoor environment; if the vehicle is in an outdoor environment, determine that the vehicle meets the leakage detection conditions.

[0149] Furthermore, the leakage detection module 40 is also used to determine a third judgment value based on the first humidity judgment value and a preset correction coefficient; if the leakage detection value is less than or equal to the second humidity judgment value, the vehicle is determined not to leak; if the leakage detection value is greater than the second humidity judgment value and less than the first humidity judgment value, the vehicle is determined to leak, and the leakage level is considered to be at risk; if the leakage detection value is greater than the first humidity judgment value and less than the third judgment value, the vehicle is determined to leak, and the leakage level is considered to be minor; if the leakage detection value is greater than or equal to the third judgment value, the vehicle is determined to leak, and the leakage level is considered to be severe.

[0150] Furthermore, the leakage detection module 40 is also used to acquire leakage detection results; if the leakage detection result is that the vehicle is leaking, then the degree of leakage of the vehicle is acquired; the handling strategy corresponding to the degree of leakage is acquired; and the vehicle is controlled according to the handling strategy to avoid damage to the vehicle.

[0151] Furthermore, the data lookup module 20 is also used to obtain the vehicle model information of the vehicle; and to look up the corresponding first humidity determination value and second humidity determination value based on the vehicle model information and the location information.
