Description

Technical Field

[0001] The present disclosure relates to the field of vehicle safety technology, and in particular to a vehicle early warning method, device, vehicle, and computer-readable storage medium. Background Art

[0002] Usually, under extreme weather conditions such as heavy rain and floods, vehicles parked in low-lying areas or areas prone to water accumulation are easily damaged by water.

[0003] In related technologies, information about water accumulation on the road is obtained through on-board cameras and radars installed on the vehicle while the vehicle is driving, and a water accumulation warning is issued based on the road water accumulation information. That is, the existing method requires the vehicle to be started and the water accumulation information is obtained through sensing systems such as lidar for warning. When the vehicle is turned off, it is impossible to timely warn of rising water levels, resulting in the user being unable to respond in time, increasing the risk of vehicle damage. Summary of the Invention

[0004] In order to solve the above technical problems or at least partially solve the above technical problems, the present disclosure provides a vehicle early warning method, device, vehicle and computer-readable storage medium.

[0005] An embodiment of the present disclosure provides a vehicle warning method, which is applied to a vehicle, wherein the vehicle is in an ignition-off state and a float assembly is provided at the bottom of the vehicle. The method includes: receiving a circuit signal triggered by the float assembly, and obtaining the current water level of the vehicle based on a water level sensor; calculating a current voltage value based on the current water level, the power supply voltage of the water level sensor, and a maximum monitoring range; and when the current voltage value is greater than or equal to a preset voltage threshold, issuing a warning according to a preset warning method.

[0006] Optionally, the method further includes: obtaining the immersion volume of the float assembly, and performing calculation based on preset buoyancy calculation parameters and the immersion volume to obtain the current buoyancy of the float assembly; when the current buoyancy is greater than or equal to a preset buoyancy threshold, triggering the circuit signal according to a preset switching method.

[0007] Therefore, the circuit signal is triggered by comparing the real-time buoyancy of the float assembly with the pre-set buoyancy threshold to control the circuit switch, thereby ensuring that when the water level around the vehicle reaches a certain water level, the vehicle water level detection judgment and warning are triggered, saving vehicle energy consumption, improving water level detection efficiency and ensuring water level warning effect.

[0008] Optionally, the method further includes: obtaining a preset preload value and the weight of the float assembly; performing calculation based on the weight and preset gravity calculation parameters to obtain the gravity value of the float assembly; and determining the buoyancy threshold based on the preload value and the gravity value.

[0009] Therefore, the buoyancy threshold is determined by the preload value to avoid the float assembly from falsely triggering the circuit signal, thereby ensuring the accuracy of subsequent warnings.

[0010] Optionally, the method further includes: determining a minimum immersion volume of the float assembly based on the buoyancy threshold; obtaining vehicle information of the vehicle and the minimum immersion volume to determine a setting position and a setting height of the float assembly to set the float assembly at the bottom of the vehicle.

[0011] Therefore, the setting position and setting height of the float assembly are determined by the vehicle information and the minimum immersion volume of the vehicle to set the float assembly at the bottom of the vehicle, which can ensure the safety of the float assembly to ensure real-time and accurate detection of buoyancy, thereby accurately triggering the circuit signal and finally ensuring the accuracy and timeliness of the early warning.

[0012] Optionally, before determining that the current voltage value is greater than or equal to a preset voltage threshold and issuing an early warning according to a preset early warning method, it also includes: after a preset period of time, if the current voltage value is less than the voltage threshold, no early warning processing is performed; or, if the current voltage value is greater than or equal to the voltage threshold, an early warning is issued according to the early warning method.

[0013] Therefore, by setting an alarm waiting time, an accurate warning can be issued when the rising water level is a continuous state, ensuring the accuracy of the warning while improving the user experience of using the warning function.

[0014] Optionally, the voltage threshold includes a first voltage threshold and a second voltage threshold; wherein, the first voltage threshold is less than the second voltage threshold, and when the current voltage value is greater than or equal to a preset voltage threshold, an early warning is performed in accordance with a preset early warning method, including: when the current voltage value is greater than or equal to the first voltage threshold and less than the second voltage threshold, turning on the first light of the vehicle and displaying a prompt message on the target display screen of the vehicle, and generating a data packet of the current water level height and the vehicle status of the vehicle and sending it to a preset target device; when the current voltage value is greater than or equal to the second voltage threshold, turning on the second light of the vehicle and the target sound device, and broadcasting the prompt message by voice, and generating a data packet of the current water level height, the position coordinate information of the vehicle and the water level monitoring timestamp and sending it to the target device.

[0015] Therefore, by setting different voltage thresholds, different warning water level heights can be warned in different warning methods. While achieving warning diversity, different warning methods can be used to timely understand the warning information of different water level heights, so that the vehicle can be handled accordingly to avoid the vehicle being soaked in water, reducing maintenance costs and inconvenience in use.

[0016] Optionally, after the current voltage value is greater than or equal to the first voltage threshold and less than the second voltage threshold, the method further includes: obtaining current rainfall data based on a rain sensor and / or obtaining predicted rainfall data based on a target platform, and determining a predicted water level height based on the current rainfall data and / or the predicted rainfall data; calculating a predicted voltage value based on the predicted water level height, the power supply voltage of the water level sensor and the maximum monitoring range; when the predicted voltage value is greater than or equal to the second voltage threshold, sending the predicted water level height to the target device.

[0017] Therefore, the current rainfall data is obtained in combination with the rain sensor and / or the predicted rainfall data is obtained based on the target platform to predict the water level height, and the user is notified when the predicted water level height meets the warning conditions, so that the user can understand the impending water accumulation in advance, so that there is sufficient time to use flexible methods to avoid the vehicle from being soaked in water, further improving the flexibility of the warning method and the safety of the vehicle.

[0018] Optionally, the method further includes: obtaining a preset maximum data transmission rate; obtaining the data volume of the data packet, and adjusting the sending interval of the data packet based on the maximum data transmission rate and the data volume.

[0019] Therefore, by adjusting the interval between sending data packets, the successful sending of data is guaranteed to ensure timely warning, thereby effectively avoiding vehicle damage.

[0020] Optionally, the method further includes: acquiring environmental information of the vehicle based on the position coordinate information of the vehicle; and adjusting the voltage threshold based on the environmental information.

[0021] Therefore, by flexibly adjusting the voltage threshold according to the vehicle's environmental information, the warning conditions can be flexibly adjusted to meet the warning needs of different vehicles and different parking positions, ensuring the timeliness and accuracy of the warning.

[0022] An embodiment of the present disclosure also provides a vehicle warning device, which is applied to a vehicle, wherein the vehicle is in an engine-off state, and a float assembly is provided at the bottom of the vehicle. The device includes: a receiving and obtaining module, which is used to receive a circuit signal triggered by the float assembly and obtain the current water level height of the vehicle based on a water level sensor; a calculation module, which is used to calculate the current voltage value based on the current water level height, the power supply voltage of the water level sensor and the maximum monitoring range; and an early warning module, which is used to issue an early warning according to a preset early warning method when the current voltage value is greater than or equal to a preset voltage threshold.

[0023] Therefore, by triggering the circuit signal through the float component, it is possible to trigger the voltage value judgment when the water accumulation at the bottom of the vehicle reaches a certain water level, saving vehicle energy consumption while ensuring effective early warning detection of the vehicle, and converting the current water level height into a voltage value and comparing it with the voltage threshold to further ensure the accuracy of the judgment, thereby improving the accuracy and timeliness of the early warning, and can effectively enhance the water level early warning capability of the vehicle when the engine is off, reduce the risk of vehicle damage, and improve vehicle safety.

[0024] An embodiment of the present disclosure also provides an electronic device, which includes: a processor; a memory for storing executable instructions of the processor; the processor is used to read the executable instructions from the memory and execute the instructions to implement the vehicle warning method provided by the embodiment of the present disclosure.

[0025] An embodiment of the present disclosure further provides a computer-readable storage medium, wherein the storage medium stores a computer program, and the computer program is used to execute the vehicle warning method provided by the embodiment of the present disclosure.

[0026] An embodiment of the present disclosure further provides a computer program product, including a computer program, wherein the computer program is executed by a processor as the vehicle warning method provided by an embodiment of the present disclosure.

[0027] The technical solution provided by the embodiments of the present disclosure has the following advantages over the prior art: the vehicle warning solution provided by the embodiments of the present disclosure, when applied to a vehicle, receives a circuit signal triggered by a float assembly located at the bottom of the vehicle when the vehicle is in the off state, obtains the current water level of the vehicle through a water level sensor, calculates the current voltage value based on the current water level, the power supply voltage of the water level sensor, and the maximum monitoring range, and issues a warning according to a preset warning method when the current voltage value is greater than or equal to a preset voltage threshold. Thus, by triggering the circuit signal by the float assembly, a voltage value judgment can be triggered when water accumulation under the vehicle reaches a certain water level, thereby ensuring effective vehicle warning detection while saving vehicle energy consumption. The current water level is converted into a voltage value and compared with the voltage threshold to ensure judgment accuracy, enabling real-time monitoring of the water accumulation condition in the vehicle's surrounding environment. When the voltage value is greater than or equal to the voltage threshold, an automatic warning is issued, thereby effectively solving the risk of the vehicle being immersed in water when the vehicle is in the off state, thereby improving the accuracy and timeliness of the warning, and effectively improving the water level warning capability of the vehicle in the off state, reducing the risk of vehicle damage, and improving vehicle safety.

[0028] The above description is only an overview of the technical solution of the present disclosure. In order to more clearly understand the technical means of the present disclosure, it can be implemented in accordance with the contents of the specification.

[0035] The following describes embodiments of the present disclosure in more detail with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.

[0036] It should be understood that the various steps described in the method embodiments of the present disclosure may be performed in different orders and / or in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present disclosure is not limited in this respect.

[0037] As used herein, the term "including" and its variations are open-ended, i.e., "including but not limited to." The term "based on" means "based, at least in part, on." The term "one embodiment" means "at least one embodiment," the term "another embodiment" means "at least one additional embodiment," and the term "some embodiments" means "at least some embodiments." Other terms are defined in the following description.

[0038] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0039] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".

[0040] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0041] In actual applications, in scenarios such as heavy rain, vehicles parked in low-lying areas or areas prone to water accumulation are very likely to suffer from water damage. The existing method uses sensing devices such as lidar on the vehicle to obtain water accumulation information and issue warnings. However, this method only has a water level monitoring function when the vehicle is started. If the vehicle is in the off state, it cannot timely issue a warning of rising water levels, resulting in users being unable to respond in time and increasing the risk of vehicle damage.

[0042] In response to the technical problems that the above-mentioned existing methods are unable to detect water accumulation in the vehicle's surrounding environment in real time when the vehicle is turned off, and lack an effective water accumulation warning mechanism, which makes it impossible for users to respond quickly to sudden rainfall and other situations to protect the vehicle from water damage, the present disclosure proposes a vehicle warning solution, which is applied to the vehicle. After the vehicle is in the off state and receives a circuit signal triggered by a float assembly set at the bottom of the vehicle, the current water level height of the vehicle is obtained through a water level sensor, and the current voltage value is calculated based on the current water level height, the power supply voltage of the water level sensor and the maximum monitoring range. When the current voltage value is greater than or equal to the preset voltage threshold, an early warning is issued according to the preset early warning method. Therefore, by triggering the circuit signal through the float component, it is possible to trigger the voltage value judgment when the water accumulation at the bottom of the vehicle reaches a certain water level, saving vehicle energy consumption while ensuring effective early warning detection of the vehicle, and converting the current water level into a voltage value and comparing it with the voltage threshold to ensure the accuracy of the judgment, so as to realize real-time monitoring of the water accumulation condition in the vehicle's surrounding environment, and automatically issue an early warning when the voltage value is greater than or equal to the voltage threshold, thereby effectively solving the risk problem of being soaked in water when the vehicle is turned off, thereby improving the accuracy and timeliness of the early warning, and can effectively improve the water level early warning capability of the vehicle when the vehicle is turned off, reduce the risk of vehicle damage, and improve vehicle safety.

[0043] Figure 1 This is a flow chart of a vehicle warning method provided by an embodiment of the present disclosure. The vehicle warning method can be executed by a vehicle warning device, wherein the vehicle warning device can be implemented using software and / or hardware and can generally be integrated into a vehicle. Figure 1 As shown, the vehicle early warning method is applied to a vehicle, comprising:

[0044] Step 101: Receive a circuit signal triggered by a float assembly, and obtain the current water level of the vehicle based on a water level sensor.

[0045] In the embodiment of the present disclosure, the float assembly is arranged at the bottom of the vehicle and at a certain distance from the ground. As the water level at the bottom of the vehicle rises, the float assembly can contact the accumulated water and can float up and down according to the changes in the water level, thereby triggering a circuit signal; wherein, the float assembly can control a circuit switch (such as a magnetic switch or a lever switch, etc.) to trigger the circuit signal.

[0046] In the embodiment of the present disclosure, a vehicle being in an ignition-off state refers to a state in which the vehicle engine stops running and the vehicle cannot continue to travel, which can generally be understood as a scene of being parked in a fixed position.

[0047] It can be understood that only when the accumulated water level reaches a certain height will the float assembly obtain buoyancy to open the circuit switch and trigger the circuit signal. Therefore, when the circuit signal triggered by the float assembly is received, the water level sensor that controls the vehicle starts working to obtain the current water level of the vehicle; wherein, the current water level refers to the water level of the accumulated water on the ground at the current moment.

[0048] Specifically, when a vehicle is parked in a fixed parking position, a float assembly located at the bottom of the vehicle monitors the water level around it in real time. When the water level reaches a certain height, the float assembly generates buoyancy and triggers a circuit switch to open. This triggers the vehicle to receive a circuit signal and control a water level sensor to obtain the vehicle's current water level. This allows the buoyancy assembly to monitor the vehicle's water level in real time, ensuring that water level detection is triggered only when the water level around the vehicle reaches a certain height. This ensures that the vehicle effectively triggers warning detection while also saving energy.

[0049] Step 102: Calculate the current voltage value based on the current water level, the power supply voltage of the water level sensor, and the maximum monitoring range.

[0050] In an embodiment of the present disclosure, a water level sensor is provided on the vehicle. After a circuit signal is triggered, the water level sensor starts to work and obtains the current water level height of the vehicle in real time.

[0051] In the embodiment of the present disclosure, the water level sensor has a corresponding power supply voltage, which is usually a fixed voltage value such as 5V; the water level sensor has a corresponding maximum monitoring range, that is, the water level sensor can monitor the maximum water level height, such as 80 cm; it can be understood that different sensors have different corresponding power supply voltages and maximum monitoring ranges, and the water level sensor should be selected according to the actual application.

[0052] Specifically, the current voltage value is obtained by multiplying the current water level by the power supply voltage and dividing the result by the maximum monitoring range.

[0053] Step 103: When the current voltage value is greater than or equal to the preset voltage threshold, an early warning is issued according to a preset early warning method.

[0054] In the embodiment of the present disclosure, a voltage threshold is set in advance, and the minimum warning water level height can be determined based on vehicle information such as the vehicle chassis height, that is, the water level height at which a warning is required, and the product value of the minimum warning water level height and the power supply voltage is divided by the maximum monitoring range to obtain the voltage threshold.

[0055] Specifically, the current voltage value is compared with a preset voltage threshold value. When the current voltage value is greater than or equal to the preset voltage threshold value, an early warning is issued according to a preset early warning method.

[0056] In an embodiment of the present disclosure, when the current voltage value is greater than or equal to a preset voltage threshold, there are many ways to issue an early warning according to a preset early warning method. In some embodiments, when the current voltage value is greater than or equal to the voltage threshold, the vehicle alarm is controlled, and a data packet is generated for the current water level height and the vehicle status and sent to a preset target device.

[0057] In other embodiments, the voltage threshold includes a first voltage threshold and a second voltage threshold; wherein the first voltage threshold is less than the second voltage threshold, and when the current voltage value is greater than or equal to the first voltage threshold and less than the second voltage threshold, the first light of the vehicle is turned on and a prompt message is displayed on the target display screen of the vehicle, and a data packet of the current water level height and the vehicle status is generated and sent to a preset target device; when the current voltage value is greater than or equal to the second voltage threshold, the second light of the vehicle and the target sound device are turned on, and a prompt message is broadcast by voice, and a data packet of the current water level height, the position coordinate information of the vehicle and the water level monitoring timestamp is generated and sent to the target device. The above two methods are only examples. The embodiments of the present disclosure do not compare the current voltage value with the preset voltage threshold. When the current voltage value is greater than or equal to the preset voltage threshold, specific restrictions are made according to the preset warning method.

[0058] It should be noted that when the current voltage value is less than the voltage threshold, the current water level voltage value is obtained in real time for comparison and judgment to ensure the timeliness of the early warning.

[0059] The vehicle warning scheme provided by the embodiments of the present disclosure is applied to a vehicle. When the vehicle is in the off state, after receiving a circuit signal triggered by a float assembly disposed at the bottom of the vehicle, the vehicle's current water level is obtained through a water level sensor. The current voltage value is calculated based on the current water level, the supply voltage of the water level sensor, and the maximum monitoring range. When the current voltage value is greater than or equal to a preset voltage threshold, an early warning is issued according to a preset early warning method. Thus, by triggering the circuit signal by the float assembly, a voltage value judgment can be triggered when water accumulation under the vehicle reaches a certain water level, thereby ensuring effective early warning detection of the vehicle while saving vehicle energy consumption. The current water level is converted into a voltage value and compared with the voltage threshold to ensure judgment accuracy, thereby achieving real-time monitoring of the water accumulation condition in the vehicle's surrounding environment. When the voltage value is greater than or equal to the voltage threshold, an automatic early warning is issued, thereby effectively resolving the risk of the vehicle being immersed in water when the vehicle is in the off state, thereby improving the accuracy and timeliness of early warning, and effectively enhancing the water level early warning capability of the vehicle in the off state, reducing the risk of vehicle damage, and improving vehicle safety.

[0060] In some embodiments, the vehicle warning method further includes: obtaining the immersed volume of the float assembly, and performing calculations based on preset buoyancy calculation parameters and the immersed volume to obtain the current buoyancy of the float assembly; when the current buoyancy is greater than or equal to a preset buoyancy threshold, triggering a circuit signal according to a preset switching method.

[0061] In the embodiment of the present disclosure, the immersed volume refers to the volume of the float assembly in contact with water; the pre-set buoyancy calculation parameters include the density of water (1000kg / m3) and the acceleration of gravity of 9.8m / s 2 .

[0062] Specifically, as the water level around the vehicle continues to rise, a float assembly, located at the bottom of the vehicle and a certain distance from the ground, can contact the water, thereby obtaining the submerged volume of the float assembly in real time. The submerged volume is then multiplied by the density of water and then by the acceleration of gravity to obtain the float assembly's current buoyancy. The current buoyancy is then compared with a preset buoyancy threshold. When the current buoyancy is greater than or equal to the preset buoyancy threshold, a circuit signal is triggered according to a preset switching method. Thus, by comparing the real-time buoyancy of the float assembly with the preset buoyancy threshold, the circuit switch triggers the circuit signal, ensuring that the vehicle water level detection and warning is triggered when the water level around the vehicle reaches a certain level, saving vehicle energy consumption, improving water level detection efficiency, and ensuring water level warning effectiveness.

[0063] It should be noted that when the current buoyancy is less than the buoyancy threshold, the immersed volume of the float assembly is obtained in real time to calculate the current buoyancy for comparison and judgment to ensure timely warning.

[0064] In the embodiment of the present disclosure, a switching mode of the trigger circuit signal is pre-set, such as a magnetic switch or a lever switch. Taking the lever switch as an example, as the current buoyancy increases, the lever starts to move with the fulcrum, thereby turning on the switch to trigger the circuit signal.

[0065] In an embodiment of the present disclosure, a buoyancy threshold is pre-set. In some embodiments, a preset preload value and the weight of the float assembly are obtained; a calculation is performed based on the weight and preset gravity calculation parameters to obtain the gravity value of the float assembly; and the buoyancy threshold is determined based on the preload value and the gravity value.

[0066] Among them, the pre-set preload value is understood to be that the pre-set switch mode, such as magnetic switch or lever switch, has a connection relationship. In order to avoid false triggering and enhance the reliability and tightness of the connection, the pre-set force value is added. Among them, the pre-set gravity calculation parameters include the gravity acceleration of 9.8m / s 2 .

[0067] In this disclosed embodiment, the float assembly's gravity value is obtained by multiplying its weight by the acceleration of gravity. This gravity value and the preload value are then added together to form the buoyancy threshold. Thus, the preload value is used to determine the buoyancy threshold, preventing the float assembly from falsely triggering circuit signals and ensuring the accuracy of subsequent warnings.

[0068] Specifically, after setting the buoyancy threshold, the buoyancy threshold can be used as the minimum buoyancy of the trigger circuit signal, so that the minimum buoyancy is divided by the density of water and then by the acceleration of gravity to obtain the minimum immersion volume of the float assembly.

[0069] It is understandable that the setting position and setting height of the float assembly at the bottom of the vehicle are different, and the current buoyancy of the float assembly is different at different water levels. In order to further ensure the accuracy of vehicle early warning, in some embodiments, the minimum immersion volume of the float assembly is determined based on the buoyancy threshold, and the vehicle information and the minimum immersion volume are obtained to determine the setting position and setting height of the float assembly to set the float assembly at the bottom of the vehicle.

[0070] Among them, vehicle information refers to the distance between the vehicle chassis and the ground, the distance between the lowest point of the vehicle bottom and the ground, and the vehicle's waterproof settings; the setting position refers to the specific position where the float assembly is set at the bottom of the vehicle; and the setting height refers to the distance between the float assembly and the ground.

[0071] It's understandable that for the same water level, float assemblies set at different heights will produce different immersed volumes. The minimum height of the float assembly can be determined based on the minimum immersed volume, and the minimum height can be adjusted based on vehicle information to determine the final height. Furthermore, the placement of the float assembly must be determined based on the layout of the various components on the vehicle's underside. Therefore, by determining the float assembly's placement and height based on vehicle information and the minimum immersed volume, and thus positioning the float assembly on the vehicle's underside, the safety of the float assembly can be ensured, enabling accurate real-time buoyancy detection. This accurately triggers circuit signals, ultimately ensuring the accuracy and timeliness of early warnings.

[0072] In the above scheme, the real-time buoyancy trigger circuit signal of the float component ensures that the vehicle effectively triggers the early warning detection while saving vehicle energy consumption. At the same time, it ensures that the water level detection is triggered when the water level around the vehicle reaches a certain water level, and the buoyancy threshold is determined by the preload value to avoid the float component from falsely triggering the circuit signal, thereby ensuring the accuracy of subsequent early warnings, and setting the setting position and setting height of the float component according to vehicle information such as the minimum immersion volume and the specific chassis height of the vehicle to meet the accurate early warning needs of different vehicles.

[0073] In some embodiments, before determining that the current voltage value is greater than or equal to a preset voltage threshold and issuing an early warning according to a preset early warning method, it also includes: after a preset time period, the current voltage value is less than the voltage threshold and no early warning processing is performed; or, the current voltage value is greater than or equal to the voltage threshold and an early warning is issued according to the early warning method.

[0074] In actual application scenarios, vehicles are parked in fixed locations, and the water level around the vehicle may temporarily rise due to other vehicles passing by. Therefore, after determining that the current voltage value is greater than or equal to the preset voltage threshold, a waiting period can be pre-set, that is, the preset period. If the current voltage value is still greater than or equal to the voltage threshold, an early warning is issued according to the early warning method. If the current voltage value is less than the voltage threshold, no early warning is processed. Therefore, by setting an alarm waiting period, it is possible to accurately issue an early warning when the water level rise is a continuous state, ensuring the accuracy of the early warning while improving the user experience of using the early warning function.

[0075] In some embodiments, the voltage threshold includes a first voltage threshold and a second voltage threshold; wherein, the first voltage threshold is less than the second voltage threshold, and when the current voltage value is greater than or equal to the preset voltage threshold, an early warning is performed in accordance with a preset early warning method, including: when the current voltage value is greater than or equal to the first voltage threshold and less than the second voltage threshold, turning on the first light of the vehicle and displaying a prompt message on the target display screen of the vehicle, and generating a data packet of the current water level height and the vehicle status of the vehicle and sending it to a preset target device; when the current voltage value is greater than or equal to the second voltage threshold, turning on the second light of the vehicle and the target sound device, and broadcasting the prompt message by voice, and generating a data packet of the current water level height, the vehicle's position coordinate information and the water level monitoring timestamp and sending it to the target device.

[0076] Among them, a first voltage threshold and a second voltage threshold are set in advance, and the first voltage threshold is smaller than the second voltage threshold; based on the description of the above embodiment, it can be determined that different voltage thresholds correspond to different warning water level heights, and a higher voltage threshold indicates a greater warning water level height.

[0077] In an embodiment of the present disclosure, when the current voltage value is greater than or equal to the first voltage threshold and less than the second voltage threshold, it indicates that the current water level is greater than or equal to the warning water level corresponding to the first voltage threshold but less than the warning water level corresponding to the second voltage threshold. An early warning is issued by turning on the first light of the vehicle and displaying a prompt message on the target display screen of the vehicle, as well as generating a data packet of the current water level and the vehicle status of the vehicle and sending it to a preset target device.

[0078] Among them, the first light refers to the vehicle's yellow warning light, the target display screen refers to the vehicle's central control screen; the vehicle status refers to the vehicle's battery level and window switch light information, and the specific settings are selected according to the actual scenario; the target device can be a mobile phone, smart wearable device, and tablet computer, etc., and the specific settings are selected according to the actual scenario.

[0079] In the embodiment of the present disclosure, the current voltage value is continued to be obtained for comparison and judgment. When the current voltage value is greater than or equal to the second voltage threshold, it indicates that the current water level is greater than or equal to the warning water level corresponding to the second voltage threshold, that is, the current water level is higher than before, and further warning is required, thereby turning on the second light and target sound device of the vehicle, and announcing the prompt information by voice, and generating a data packet of the current water level, the vehicle's position coordinate information and the water level monitoring timestamp and sending it to the target device.

[0080] Among them, the second light refers to the red light of the vehicle; the target sound device refers to the vehicle's buzzer and other voice devices; the vehicle's position coordinate information refers to the vehicle's latitude and longitude coordinates, which can be obtained through the vehicle's positioning system.

[0081] Therefore, by setting different voltage thresholds, different warning water level heights can be warned in different warning methods. While achieving warning diversity, different warning methods can be used to timely understand the warning information of different water level heights, so that the vehicle can be handled accordingly to avoid the vehicle being soaked in water, reducing maintenance costs and inconvenience in use.

[0082] It is understandable that in a rainy scenario, factors such as the amount of rain and duration at the vehicle's location can affect the length of time the water level around the vehicle rises. Therefore, after the current voltage value is greater than or equal to the first voltage threshold and less than the second voltage threshold, in order to further improve the accuracy of the early warning, in some embodiments, current rainfall data is obtained based on the rain sensor and / or predicted rainfall data is obtained based on the target platform, and the predicted water level height is determined based on the current rainfall data and / or the predicted rainfall data; the predicted voltage value is calculated based on the predicted water level height, the power supply voltage of the water level sensor, and the maximum monitoring range; when the predicted voltage value is greater than or equal to the second voltage threshold, the predicted water level height is sent to the target device.

[0083] Among them, the rain sensor installed on the vehicle can obtain the specific rainfall at the current moment, that is, the current rainfall data; the target platform can be a cloud-based weather forecast platform, which can obtain the specific rainfall within the predicted time period, such as half an hour or one hour, based on the vehicle's location information, that is, the predicted rainfall data.

[0084] Next, the current rainfall data and / or predicted rainfall data are processed by a water level prediction algorithm to obtain the predicted water level height. That is to say, the current water level height of the vehicle half an hour or an hour later can be predicted according to the current rainfall data and / or predicted rainfall data, that is, the predicted water level height; wherein, the water level prediction algorithm can be determined by processing historical rainfall data.

[0085] Furthermore, a predicted voltage value is calculated based on the predicted water level, the power supply voltage of the water level sensor, and the maximum monitoring range; when the predicted voltage value is greater than or equal to the second voltage threshold, the predicted water level is sent to the target device. That is, the predicted voltage value being greater than or equal to the second voltage threshold indicates that the predicted water level is greater than or equal to the warning water level corresponding to the second voltage threshold. Therefore, the predicted water level can be sent to the target device. For example, the predicted water level of the vehicle will be greater than the warning water level in half an hour, and the vehicle needs to be moved in time. Therefore, the water level is predicted by further combining the current rainfall data obtained by the rain sensor and / or obtaining the predicted rainfall data based on the target platform, and notifying the user when the predicted water level meets the warning conditions. This allows the user to understand the impending waterlogging situation in advance, so that they have sufficient time to use flexible methods to prevent the vehicle from being soaked in water, further improving the flexibility of the warning method and the safety of the vehicle.

[0086] Based on the above embodiments, warning data is sent to the target device via data packets. Therefore, it is necessary to ensure the real-time and effectiveness of data transmission. In some embodiments, a preset maximum data transmission rate is obtained; the data volume of the data packet is obtained, and the interval between sending the data packet is adjusted based on the maximum data transmission rate and the data volume.

[0087] The preset maximum data transmission rate refers to the maximum data transmission rate that the communication module on the vehicle can support.

[0088] Specifically, the data volume of the data packet is obtained, the data volume is divided by the maximum data transmission rate to obtain a sending interval, and the data packet is sent according to the sending interval.

[0089] In the disclosed embodiment, it is also possible to prioritize the importance of each data in the data packet, so that the data is sent according to the priority of the data, further improving the timeliness of the data warning.

[0090] Therefore, by adjusting the interval between sending data packets, the successful sending of data is guaranteed to ensure timely warning, thereby effectively avoiding vehicle damage.

[0091] In some embodiments, the vehicle warning method further includes: acquiring environmental information of the vehicle based on the location coordinate information of the vehicle; and adjusting the voltage threshold based on the environmental information.

[0092] In the disclosed embodiment, the vehicle's location coordinate information, such as longitude and latitude coordinates, can be obtained through the vehicle's positioning system, thereby obtaining the vehicle's environmental information, such as whether there is a river around the vehicle's location and the river water level. Based on the vehicle's environmental information, it can be determined that the river water level at the vehicle's location often rises, and therefore, it is necessary to lower the warning water level, that is, lower the voltage threshold. Thus, by flexibly adjusting the voltage threshold based on the vehicle's environmental information, the warning conditions can be flexibly adjusted to meet the warning requirements of different vehicles and different parking locations, ensuring the timeliness and accuracy of the warning.

[0093] Based on the description of the above embodiment, the water accumulation condition of the vehicle's surrounding environment can be monitored in real time. When the water level reaches a certain level, an early warning message is automatically sent to the target device, thereby effectively solving the risk of the vehicle being soaked by rainwater when parked. Figure 2 Provide a detailed description.

[0094] Figure 2 This is a flow chart of another vehicle warning method provided by an embodiment of the present disclosure. Based on the above embodiment, this embodiment further optimizes the above vehicle warning method.

[0095] like Figure 2 As shown, the method includes:

[0096] Step 201: Obtain the immersed volume of the float assembly, and calculate based on the preset buoyancy calculation parameters and the immersed volume to obtain the current buoyancy of the float assembly. When the current buoyancy is greater than or equal to the preset buoyancy threshold, trigger the circuit signal according to the preset switching method.

[0097] Step 202: Receive a circuit signal triggered by the float assembly, obtain the current water level of the vehicle based on the water level sensor, and calculate the current voltage value based on the current water level, the power supply voltage of the water level sensor, and the maximum monitoring range.

[0098] Step 203: If the current voltage value is greater than or equal to a preset first voltage threshold, and the current voltage value is less than the first voltage threshold after a preset time period, no warning processing is performed.

[0099] Step 204: After a preset time, when the current voltage value is greater than or equal to the first voltage threshold and less than the second voltage threshold, turn on the first light of the vehicle and display a prompt message on the target display screen of the vehicle, and generate a data packet of the current water level height and the vehicle status and send it to the preset target device.

[0100] Step 205: Obtain current rainfall data based on the rain sensor and / or obtain predicted rainfall data based on the target platform, determine the predicted water level based on the current rainfall data and / or the predicted rainfall data, calculate the predicted voltage value based on the predicted water level, the power supply voltage of the water level sensor and the maximum monitoring range, and when the predicted voltage value is greater than or equal to the second voltage threshold, send the predicted water level to the target device.

[0101] Step 206: When the current voltage value is greater than or equal to the second voltage threshold, turn on the second light of the vehicle and the target sound device, and broadcast the prompt information by voice, and generate a data packet including the current water level height, the vehicle's position coordinate information and the water level monitoring timestamp and send it to the target device.

[0102] Specifically, a float assembly is set at the bottom of the vehicle. The float assembly rises and falls with the water level and can trigger a circuit signal switch (such as a reed switch or a lever switch light) through mechanical displacement, so that the float assembly trigger signal can be converted into a circuit signal. After receiving the circuit signal, it is determined whether the warning voltage threshold is reached, and the warning and data transmission are started. It can control the sound and light alarm, the warning on the vehicle's central control screen, and the in-vehicle voice broadcast such as "The road is flooded, please pay attention to prevention", "The water level is dangerous! Please move immediately!", etc., and send warning data to the cloud server or mobile phone application through the wireless network; in addition, the vehicle has a power supply (for example, the power supply voltage is 12V), supports water short-circuit protection, and further improves vehicle safety.

[0103] For example, Figure 3As shown, step 3.1 monitors the water level in real time, that is, when the vehicle is in the off state, the water level is monitored in real time by the float component set at the bottom of the vehicle to obtain the current water level; step 3.2 determines whether the current water level is less than or equal to the preset first water level threshold, that is, by comparing the current voltage value with the preset first voltage threshold; wherein, the total distance of the vehicle from the ground is obtained, the total distance is multiplied by a preset ratio (such as 0.4) to determine the first water level threshold, and the first water level threshold is multiplied by the power supply voltage of the water level sensor and divided by the maximum monitoring range of the water level sensor to obtain the first voltage threshold; step 3.3, when the current voltage value is less than or equal to the first voltage threshold, that is, when the current water level is less than or equal to the preset first water level threshold, the water level continues to be monitored; step 3.4 when the current water level is greater than the preset first water level threshold, a first-level warning is triggered, such as triggering a yellow warning light plus a mild prompt sound, and step 3.5 generates a first-level warning data packet and sends it to a cloud server, mobile phone application, etc. For the target device, data packet transmission can be transmitted in a normal state, that is, basic data (such as water level value, vehicle status, etc.) is sent every 30 seconds; step 3.6 records and sends primary data, and determines whether the current water level is greater than or equal to the preset second water level threshold, that is, by comparing the current voltage value with the preset second voltage threshold; wherein, the total distance of the vehicle from the ground is obtained, the total distance is multiplied by a preset ratio (such as 0.7) to determine the second water level threshold, and the second water level threshold is multiplied by the power supply voltage of the water level sensor and divided by the maximum monitoring range of the water level sensor to obtain the second voltage threshold; step 3.7 When the current voltage value is greater than the second voltage threshold, that is, the current water level is greater than the preset second water level threshold, a secondary warning is triggered, triggering a red flashing plus a high-intensity buzzer plus a voice broadcast, and step 3.8 generates a secondary warning data packet, that is, a high-priority data packet (including water level, positioning coordinates, timestamp, etc.) is immediately uploaded to the cloud server, mobile phone application and other target devices.

[0104] As an example scenario, a vehicle is parked on a low-lying road and encounters heavy rain. The ground water level rises, and the float component rises with the water level, for example, 10 cm. The water level monitoring is not triggered; when the water level climbs to 32 cm (for example, 40% of the total height threshold), the yellow light is controlled to light up, and the central control screen prompts "Road flooding, please pay attention to prevention"; the ground water level continues to rise, and the water level reaches 56 cm (for example, % of the total height threshold), the buzzer controls the high-frequency alarm, the red light flashes, and the voice broadcast "Water level danger! Please move immediately!"; the positioning coordinates and water level value (for example, 32 or 56 cm) are sent to the application and background server; the user's mobile phone can also receive a text message: "Your vehicle XX has an alarm for water accumulation at XX intersection, please move immediately or seek rescue!"

[0105] In this way, the water level height under the vehicle chassis is obtained. When the water level exceeds the safety threshold (for example, the set value is 40% or 70% of the chassis height), an audible and visual alarm is triggered and the vehicle status is automatically reported to achieve real-time monitoring; an alarm message is sent to the user's mobile phone application, management platform or emergency center via a wireless network, providing vehicle location and water level data; reducing vehicle stalling, engine damage or people trapped due to wading too deep, thereby reducing risks and improving vehicle safety.

[0106] The vehicle warning solution provided by the embodiment of the present disclosure obtains the immersed volume of the float component, and calculates based on the preset buoyancy calculation parameters and the immersed volume to obtain the current buoyancy of the float component. When the current buoyancy is greater than or equal to the preset buoyancy threshold, the circuit signal is triggered according to the preset switching method, the circuit signal triggered by the float component is received, the current water level of the vehicle is obtained based on the water level sensor, the current voltage value is calculated based on the current water level, the power supply voltage of the water level sensor and the maximum monitoring range, and the current voltage value is greater than or equal to the preset first voltage threshold. After the preset time, if the current voltage value is less than the first voltage threshold, no warning processing is performed. After the preset time, when the current voltage value is greater than or equal to the first voltage threshold and less than the second voltage threshold, the first light of the vehicle is turned on and the vehicle is turned on. The target display screen displays a prompt message, and generates a data packet of the current water level height and the vehicle status and sends it to a preset target device, obtains current rainfall data based on the rain sensor and / or obtains predicted rainfall data based on the target platform, and determines the predicted water level height based on the current rainfall data and / or predicted rainfall data, calculates the predicted voltage value based on the predicted water level height, the power supply voltage of the water level sensor and the maximum monitoring range, and sends the predicted water level height to the target device when the predicted voltage value is greater than or equal to a second voltage threshold. When the current voltage value is greater than or equal to the second voltage threshold, turns on the second light and target sound device of the vehicle, and voice broadcasts the prompt message, and generates a data packet of the current water level height, the vehicle's position coordinate information and the water level monitoring timestamp and sends it to the target device. In this way, water accumulation warnings can be broadcast immediately, effectively avoiding vehicle damage and ensuring the real-time nature of vehicle warnings; the disclosed embodiments can also reduce false alarms and improve warning accuracy; that is, in an emergency, the owner can be automatically notified without manual operation, which is convenient to use and improves the user experience; early warnings can be given to avoid vehicles being soaked in water, reducing maintenance costs and inconvenience; and the vehicle's ability to perceive environmental changes can be increased, thereby improving overall driving and parking safety.

[0107] In this disclosed embodiment, after issuing a warning using a pre-set warning method, the vehicle's current water level and location coordinates can be sent to a target server. The target server then generates a waterlogging heat map based on all the current water level and location coordinates and sends it to the vehicle, which then controls the vehicle's driving based on the heat map. This allows for fleet networking, where multiple vehicles can share waterlogging data, creating a real-time road waterlogging heat map, further enriching vehicle warning scenarios and improving vehicle safety.

[0108] In some embodiments, for vehicle driving scenarios, the vehicle can be controlled to automatically deviate to avoid deep water areas for automatic driving, thereby further improving vehicle safety.
