Description

Technical Field

[0001] This invention relates to the technical field of automotive safety, and in particular to a method, device, and vehicle for protecting vehicles from water wading. Background Technology

[0003] For new energy vehicles, if professional inspection and treatment are not carried out in time after the vehicle has been submerged in water, it is very easy for water to enter the core components such as the battery pack, drive motor, and electronic control system, which may lead to safety hazards such as short circuits and insulation failures. In severe cases, it may cause secondary electrical failures or traffic accidents.

[0004] However, existing detection technologies still have significant shortcomings in assessing the condition of vehicles that have been submerged in water. For example, current mainstream detection methods still rely on repair personnel to visually inspect or disassemble components such as air filters and chassis skid plates, which is not only inefficient and costly, but also makes it difficult to identify hidden damage such as oxidation of the vehicle's ECU (Electronic Control Unit) circuits and failure of bearing lubrication.

[0005] Furthermore, existing vehicle systems generally adopt a passive vehicle water wading fault warning mechanism, which only issues an alarm after a fault code is triggered (such as a motor controller error). This makes it impossible to predict potential risks in the critical time after water wading, leading to the continuous deterioration of water damage to the vehicle and reducing the user's driving experience. Summary of the Invention

[0011] In conjunction with the first possible implementation of the first aspect, this embodiment of the invention provides a fourth possible implementation of the first aspect, wherein the step of generating protective measures matching the wading level includes: if the wading level is a low-risk level, sending a first warning message to the user terminal corresponding to the vehicle; and generating a recommended transfer area based on the current location information of the vehicle to guide the user to avoid wading risks.

[0012] In conjunction with the second possible implementation of the first aspect, this embodiment of the invention provides a fifth possible implementation of the first aspect, wherein the step of generating protective measures matching the wading level further includes: if the wading level is a medium-risk level, then searching for the pre-configured authorization permissions corresponding to the vehicle; if the authorization permissions are granted, then generating a recommended transfer area based on the current location information of the vehicle; controlling the vehicle to start an intelligent driving mode, and in the intelligent driving mode, controlling the vehicle to drive to the recommended transfer area.

[0013] In conjunction with the fifth possible implementation of the first aspect, this embodiment of the invention provides a sixth possible implementation of the first aspect, wherein the above method further includes: if the authorization permission is prohibited, generating a second warning message according to a pre-configured medium-risk level prompting method; and sending the second warning message to the user terminal corresponding to the vehicle to provide a warning prompt.

[0014] In conjunction with the third possible implementation of the first aspect, this embodiment of the invention provides a seventh possible implementation of the first aspect, wherein the step of generating protective measures matching the wading level further includes: if the wading level is a high-risk level, initiating a pre-configured protective operation, wherein the protective operation includes at least: circuit isolation operation, battery pack protection operation, and charging port locking operation; and generating third warning information and sending the third warning information to the user terminal corresponding to the vehicle, wherein the third warning information carries a real-time image of the vehicle.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Currently, most in-vehicle systems use a passive fault warning mechanism, which only issues an alarm after a fault code is triggered (such as a motor controller error). This makes it impossible to predict potential risks in the critical time after wading through water, leading to continuous deterioration of vehicle damage. Based on this, the present invention provides a vehicle water wading protection method, device and vehicle, which can realize dynamic assessment of water wading risk level and autonomous execution of safety protection measures according to water wading depth and data from environmental sensors, effectively improving the vehicle's safety protection capability and maintenance response time after water wading.

[0024] To facilitate understanding of this embodiment, a method for protecting vehicles from water wading, as disclosed in this embodiment of the invention, will first be described in detail.

[0025] In one possible implementation, the present invention provides a method for protecting a vehicle from water wading. The method is applied to a vehicle, and a water wading sensor and an environmental sensor are configured at a preset location on the vehicle.

[0026] In practical use, the vehicles in this embodiment of the invention include fuel-powered vehicles, new energy vehicles, and other vehicles equipped with intelligent control systems. Furthermore, the wading sensor can monitor whether the vehicle is wading through water and the water depth beneath and around the vehicle. Therefore, the wading sensor is generally installed in a location corresponding to the vehicle's chassis. Environmental sensors typically include rain sensors and humidity sensors. The rain sensor can monitor rainfall information to determine if the current weather is rainy. The humidity sensor is installed in a preset location; for example, for new energy vehicles, the preset location may include the location of the preset motor, the location corresponding to the battery system, the location corresponding to the charging port, etc., and can monitor the amount of water wading in the battery and motor, or monitor whether the charging port is dry, etc. For fuel-powered vehicles, the humidity sensor can be installed in the location corresponding to the engine. The specific setting of the environmental sensors depends on the actual usage, and this embodiment of the invention does not impose any limitations on this.

[0027] Specifically, such as Figure 1 The flowchart shown illustrates a method for protecting vehicles from water erosion, including the following steps: Step S102: Respond to the activation of the wading mode and acquire the wading information collected by the wading sensor; In practical use, the aforementioned wading mode is typically activated when the vehicle is parked. For example, after parking the vehicle at a preset location, the user can activate the wading mode according to actual needs, such as current weather conditions, regional characteristics, and geographical location. This allows the vehicle to be protected from water damage after the user leaves the vehicle. Furthermore, the vehicle can also automatically activate the wading mode after detecting that it is parked, based on its configuration. For example, in rainy seasons or cloudy weather, the vehicle controller can automatically activate the wading mode after detecting that the vehicle is parked. The specific activation of the wading mode can be set according to actual usage, and this embodiment of the invention does not impose any limitations on this.

[0028] Step S104: Determine whether the vehicle has been through water based on the water wading information; In practical use, after the wading mode is activated, the vehicle controller can acquire wading information collected by the wading sensor at preset time intervals to determine whether the vehicle has waded through water. Specifically, the wading sensor can monitor water level and flow information through devices such as ultrasonic radar sensors and water level sensors to determine whether the vehicle has waded through water.

[0029] Step S106: If so, extract the wading depth contained in the wading information, and obtain the environmental parameters collected by the environmental sensors; Step S108: Determine the vehicle's current wading level based on wading depth and environmental parameters; Step S110: Generate protective measures that match the water wading level to protect the vehicle from water wading.

[0030] In practical use, different wading depths have different wading levels. In this embodiment of the invention, in addition to the wading depth, environmental parameters collected by environmental sensors, such as rainfall information and humidity information of the current environment, are also integrated. This enables the potential risks of wading to be identified in time, and thus the current wading level of the vehicle can be determined. This allows for the generation of protective measures that match the wading level, effectively alleviating the problems of delayed response and misjudgment of risks in traditional vehicle wading protection.

[0031] This invention provides a vehicle wading protection method that responds to the activation of the wading mode and acquires wading information collected by a wading sensor; determines whether the vehicle has waded through water based on the wading information; if so, extracts the wading depth contained in the wading information and acquires environmental parameters collected by an environmental sensor; determines the vehicle's current wading level based on the wading depth and environmental parameters; and generates protective measures matching the wading level to protect the vehicle from wading. Since the wading level is determined based on the wading depth and environmental parameters, a graded response to vehicle wading can be achieved through multi-source data, effectively predicting potential risks of vehicle wading and avoiding post-flood alarms. It also helps optimize user experience and emergency response efficiency.

[0032] In practical use, vehicles are typically equipped with a central controller. The wading sensor, environmental sensor, and other devices described in this embodiment can all be connected to this central controller to collect, receive, and process environmental sensor data. Specifically, the central controller can be a separate controller that communicates with the vehicle controller, such as the vehicle controller or vehicle ECU. Alternatively, the vehicle controller can be used directly as the central processor, which can also receive and process data collected by the wading sensor, environmental sensor, and other devices. The specific implementation of the central controller depends on the actual usage, and this embodiment does not impose any limitations on it.

[0033] Furthermore, based on the aforementioned central processing unit, it is possible to receive data from environmental sensors and dynamically evaluate this data using intelligent decision-making algorithms, autonomously triggering graded response strategies. This includes pushing emergency alarm information to user terminals via the cloud platform's backend server, or performing safety operations on the vehicle, such as intelligent power-off protection of high-voltage relays according to safety protocols. Therefore, to enable communication between the vehicle and the backend server, the vehicles in this embodiment typically include a communication module. For example, a multimodal interaction design can be adopted to send warning information to the vehicle owner via SMS, user terminal interface, telephone, etc., based on real-time risk level assessment results.

[0034] In addition, vehicles equipped with intelligent control systems typically include a positioning module and an intelligent driving module. The positioning module usually integrates GPS (Global Positioning System) and high-precision electronic maps to ensure the vehicle can determine its location when wading through water and to help the driver plan a safe route. The intelligent driving module enables the vehicle to move autonomously when the driver authorizes the activation of intelligent driving mode.

[0035] Furthermore, this embodiment of the invention uses a new energy vehicle as an example to further illustrate the protection method for vehicles wading through water. Specifically, for example... Figure 2 The flowchart shown here illustrates another method for protecting vehicles from water wading, further explaining the specific steps for determining the water wading level and generating protective measures, including the following steps: Step S202: Respond to the activation of the wading mode and acquire the wading information collected by the wading sensor; Step S204: Determine whether the vehicle has been through water based on the water wading information; If yes, proceed to step S206; otherwise, return to step S202.

[0036] Step S206: Monitor whether the wading depth has reached the preset wading depth threshold; If no, proceed to step S208; if yes, proceed to step S214. Step S208: Determine whether the rainfall information monitored by the rain sensor is less than the preset rainfall threshold. If yes, proceed to step S210; if no, return to step S206 and continue monitoring the wading depth.

[0037] Step S210: Determine the vehicle's current water wading level as low risk. In practical use, the wading sensor can monitor the water level of the vehicle in real time. Furthermore, based on the characteristics of different vehicle models (such as the difference in ground clearance between sedans and SUVs), users can customize the threshold settings according to the vehicle model characteristics. At the same time, the cloud platform's backend server can also combine cloud big data analysis of the vehicle's chassis height parameters to dynamically optimize and intelligently recommend a reasonable threshold range. Therefore, the above-mentioned wading depth threshold can be set according to actual usage conditions, and this embodiment of the invention does not impose any restrictions on this.

[0038] Furthermore, when the wading sensor detects that the wading depth is below the wading depth threshold, i.e., it has not reached the preset wading depth threshold, the monitoring data from the environmental sensor is further acquired. In this embodiment of the invention, the environmental sensor includes a rain sensor. After the wading mode is activated, the rain sensor can be activated and linked to meteorological data in the cloud to obtain the rainfall situation in the future. If the rain information monitored in real time by the rain sensor shows that there is currently no rainfall, and there will be no rainfall in the future, it can be determined that there is no risk of wading for the core components of the vehicle. Therefore, the wading level at this time can be determined to be a low-risk level. That is, in this embodiment of the invention, if the wading depth is detected to be below the preset wading depth threshold, and the rainfall information monitored by the rain sensor is less than the preset rainfall threshold, the current wading level of the vehicle is determined to be a low-risk level. The rainfall information at this time can be linked to the meteorological data in the cloud for comprehensive judgment.

[0039] Furthermore, once the vehicle's current water wading level is determined to be low-risk, protective measures matching the low-risk level can be generated. Specifically, this includes the following steps: Step S212: Send the first warning information to the user terminal corresponding to the vehicle; and generate a recommended transfer area based on the vehicle's current location information to guide the user to avoid the risk of wading through water. In other words, if the flood risk level is low, a first warning message is sent to the user terminal corresponding to the vehicle; and a recommended evacuation area is generated based on the vehicle's current location information to guide the user to avoid flood risks. Specifically, for low-risk levels, the vehicle controller can send a first warning message to the user terminal corresponding to the vehicle, such as the owner's mobile phone. This first warning message may include the vehicle's current location information. Simultaneously, the vehicle's corresponding application (APP) can also recommend safe evacuation and avoidance areas based on the electronic map corresponding to the current location information, guiding the user to proactively avoid potential flood risks.

[0040] Furthermore, if meteorological data indicates that there will be continuous rainfall in the near future and the wading depth will continue to rise, the wading depth will be continuously monitored. If the wading depth is detected to reach the preset wading depth threshold, step S214 will be executed.

[0041] Step S214: If the wading depth is detected to reach the wading depth threshold, and the rainfall information monitored by the rain sensor reaches the preset rainfall threshold, then the current wading level of the vehicle is determined to be medium risk level. Specifically, in this process, the wading sensor and the rainfall sensor can work together to analyze meteorological data. For example, if current meteorological data shows continued rainfall, and the wading sensor further detects that the wading depth has reached or exceeded the wading depth threshold, and the rainfall sensor is monitoring rainfall in real time, indicating precipitation, and meteorological data shows that precipitation will continue in the future, it can be determined that continuing to park the vehicle in this location may result in the vehicle wading through water. Therefore, a medium-risk level warning will be automatically triggered. Under this medium-risk level, protective measures matching the medium-risk level can be generated, specifically including the following steps: Step S216: Find the pre-configured authorization permissions corresponding to the vehicle. If the authorization permission is "agree to authorization", generate a recommended transfer area based on the vehicle's current location information. Step S218: Control the vehicle to start the intelligent driving mode, and in the intelligent driving mode, control the vehicle to drive to the recommended transfer area; In practice, if the water level is classified as medium risk, step S216 is executed to locate the pre-configured authorization permissions for the vehicle. Further, if the user of the vehicle, i.e., the vehicle owner, has pre-configured authorization permissions via their user terminal that grant permission, the vehicle can then drive to a safe area (recommended transfer area) using intelligent driving mode. If the owner does not grant authorization and automatically activates intelligent driving mode (i.e., if authorization is denied), a second warning message is generated according to the pre-configured medium risk level prompt method; this second warning message is then sent to the user terminal of the vehicle for warning purposes. The first warning message can be sent to the owner via urgent phone call or SMS, and includes the vehicle's current location information, instructing the owner to autonomously drive away from the safe area to the recommended transfer area to help them plan their route.

[0042] Furthermore, monitoring the wading depth is a continuous process after the vehicle has driven through water until the driver leaves the wading area. Therefore, after step S214 above, the vehicle's wading status can continue to be monitored, and data from environmental sensors can be acquired. Specifically, in this embodiment of the invention, taking a new energy vehicle as an example, the environmental sensors, in addition to the aforementioned rain sensor, also include a humidity sensor located at a preset position; the preset position includes at least one of the following: the position of the preset motor, the position corresponding to the battery system, and the position corresponding to the charging port; furthermore, in this embodiment of the invention, determining the vehicle's current wading level based on the wading depth and environmental parameters also includes the following steps: Step S220: If the wading depth is detected to reach the wading depth threshold, and the humidity parameter collected by the humidity sensor reaches the preset humidity threshold, then the current wading level of the vehicle is determined to be high risk level. In practical use, in this embodiment of the invention, in addition to detecting the wading depth as a factor in determining the wading risk mode, step S220 further integrates the humidity parameters monitored by the humidity sensor. For example, if the humidity parameters of the battery, motor, or charging port are detected, it can be further determined whether a high-risk mode has been reached. Furthermore, considering that there are multiple temperature sensors, the monitoring method can be configured so that if the humidity parameter monitored by at least one humidity sensor reaches a preset humidity threshold, it can be determined as a high-risk level.

[0043] Furthermore, the aforementioned humidity threshold can also be set as a dynamic threshold. This dynamic humidity threshold can be set based on the characteristic parameters of the humidity sensor, historical data, and interference factors, and it can be determined whether to update it based on the current actual situation. The specific method of setting the humidity threshold can be set according to the actual usage situation, and the embodiments of the present invention do not limit it in this regard.

[0044] Furthermore, if the detected humidity parameter does not reach the preset humidity threshold, it means that the water wading situation, including rainfall, has little impact on the vehicle's battery, motor, and charging port at preset locations. The owner can drive to a safe area on their own or authorize the use of intelligent driving mode through the user terminal to drive to a safe area. Furthermore, if the detected humidity parameter reaches the humidity threshold, it means that the humidity of the battery, motor, or charging port is high, and water may have entered. Starting the vehicle directly would cause secondary damage to the vehicle. In this case, protective measures matching the high-risk level can be generated, specifically including the following steps.

[0045] Step S222: If the water wading level is high-risk, then initiate the pre-configured protection operation.

[0046] Specifically, if the water wading level is high-risk, a pre-configured protective operation is initiated. The protective operation in this embodiment of the invention includes at least: circuit isolation operation, battery pack protection operation, and charging port locking operation; and a third warning message is generated and sent to the user terminal corresponding to the vehicle. The third warning message carries a real-time image of the vehicle.

[0047] In actual use, the above-mentioned protective operations can be achieved through coordinated control between the Battery Management System (BMS) and the Vehicle Control Unit (VCU). Specifically, the high-voltage relay can be disconnected first to achieve physical-level circuit isolation. At the same time, the multi-layer composite sealing protection layer of the battery pack is activated to form a double barrier. The charging port is forcibly locked by an electromagnetic locking mechanism, and the air pressure expansion device in the door seal is linked to create an airtight chamber. The vehicle network can be used to remotely lock the vehicle's starting permission. For vehicles equipped with standard air suspension, the air suspension can also be automatically adjusted to the highest point of travel under the control of the VCU.

[0048] Furthermore, for third-party early warning information, vehicle owners can be notified via urgent phone calls or text messages. The notification information includes the vehicle's current location information, and real-time video feeds of the vehicle can be pushed through the vehicle's corresponding application app.

[0049] Furthermore, at high-risk levels, AI algorithms can analyze wading depth and component damage probability to automatically generate rescue plans. For example, the vehicle can automatically connect with insurance companies, dealerships, and towing services, providing multiple options for the owner to choose from. Additionally, the vehicle controller can be instructed to encrypt and store vehicle sensor data for a period before and after wading, such as 30 minutes, including data on water level changes, battery, motor, and wiring harness data. This data is then used by insurance companies to determine liability and is simultaneously uploaded to a cloud platform.

[0050] Furthermore, after the water recedes as detected by the wading sensor, the new energy vehicle can also check whether charging conditions are met using the humidity sensor at the charging port. If charging conditions are not met, the charging port cover will remain locked until the charging port is completely dry. A battery airtightness test can then be initiated, and a maintenance suggestion list will be generated. Specific analysis content can be pushed to the vehicle's corresponding app and simultaneously stored on the in-vehicle terminal.

[0051] In summary, based on Figure 2 The vehicle water wading protection method shown in this embodiment of the invention can achieve the following functions: (1) Based on the fusion function of multiple sensors, such as wading sensors and environmental sensors, the vehicle's wading depth and humidity parameters inside the power system (battery, motor compartment, charging port, etc.) are monitored in real time, and the wading level (low risk level, medium risk level, high risk level) is dynamically evaluated through fuzzy logic algorithm. (2) Construct a graded response mechanism to trigger differentiated treatment strategies for different water wading levels, that is, generate protective measures that match the water wading level to protect vehicles from water wading. (3) Introduce an authorization mechanism to perform autonomous driving operations through an authorized intelligent driving mode in order to leave the waterlogged area; (4) Under high-risk conditions, it can intelligently perform circuit isolation operations to avoid secondary damage to water-contaminated batteries and motors; (5) It can analyze the correlation between wading depth and the failure probability of core components, and intelligently link with insurance company loss assessment platforms and 4S store service systems to generate rescue routes; (6) Record all sensor data of the vehicle for a period of time before and after wading through water, such as 30 minutes, and upload it to the cloud platform. Integrate the charging port intelligent protection system, which is controlled by the humidity sensor and the electronic lock. The charging port will be unlocked after the vehicle is completely dry.

[0052] Therefore, the vehicle water wading protection method provided in this embodiment of the invention can achieve accurate identification of water wading damage, dynamic assessment of water wading level, and autonomous execution of protection strategies, effectively improving the safety protection capability and maintenance response time of vehicles, especially new energy vehicles, after water wading.
