[0006] In some embodiments, after the step of detecting whether the vehicle's main communication module receives a communication signal sent by the vehicle's secondary communication module, the vehicle submerged in water determination method further includes: if the main communication module receives the communication signal within the preset time period, determining that the vehicle is not in a submerged state.

[0007] In some embodiments, the number of slave communication modules includes multiple modules, and the step of determining that the vehicle is not in a state of being submerged in water if the master communication module receives the communication signal within the preset time period includes: if the master communication module does not receive any communication signal sent by any of the slave communication modules within the preset time period, determining that the vehicle is in a state of being submerged in water.

[0008] In some embodiments, the step of detecting whether the vehicle's main communication module receives a communication signal sent by the vehicle's slave communication module in response to the vehicle's real-time location being in a water area includes: in response to the vehicle's real-time location being in a water area, the main communication module sending tire pressure monitoring information to the slave communication module according to a preset time period; and detecting whether the main communication module receives the communication signal, including the tire pressure signal, fed back by the slave communication module based on the tire pressure monitoring information within the preset time period.

[0009] In some embodiments, after the step of detecting whether the vehicle's main communication module receives a communication signal sent by the vehicle's secondary communication module, the vehicle submerged in water determination method further includes: if the main communication module receives the heartbeat pulse signal within the preset time period, then comparing the heartbeat pulse signal with a preset standard pulse signal; and determining whether the vehicle is in a submerged state based on the degree of difference between the heartbeat pulse signal and the preset standard pulse signal.

[0010] In some embodiments, the step of determining whether the vehicle is in a state of being submerged in water based on the difference between the heartbeat pulse signal and the preset standard pulse signal includes: if the proportion of the high-level signal in the heartbeat pulse signal in a single pulse cycle of the heartbeat pulse signal is less than the proportion of the high-level signal in the standard pulse signal in a single pulse cycle of the standard pulse signal, then the vehicle is determined to be in a state of being submerged in water.

[0011] In some embodiments, prior to the step of detecting whether the vehicle's main communication module receives a communication signal sent by the vehicle's secondary communication module in response to the vehicle's real-time location being in a water area, the vehicle falling into water determination method further includes: acquiring the vehicle's current coordinates in real time; mapping the current coordinates to a preset map; and determining whether the vehicle's real-time location is in a water area based on the position of the current coordinates in the preset map.

[0012] To address the aforementioned problems, this application provides a vehicle submerged in water determination device. The device includes a detection module and a determination module. The detection module detects whether the vehicle's main communication module receives a communication signal sent by the vehicle's secondary communication module in response to the vehicle's real-time location being in a water area.

[0026] With the rapid development of the automotive industry, automobiles have become an indispensable means of transportation for people. The number of cars on the road is increasing year by year, and more and more people own private cars. This widespread adoption of automobiles has spurred the development of automotive parts manufacturing and design.

[0027] However, many unpredictable situations arise during vehicle operation. For example, in the event of an emergency, it is crucial to accurately and promptly determine the vehicle's predicament to facilitate a quick and appropriate response. For instance, if a vehicle falls into water and its current status cannot be accurately and efficiently monitored using specific methods, delayed information transmission could easily lead to serious consequences.

[0028] To address the technical problems existing in related technologies, this application provides a method for launching a vehicle into water, see [link to relevant documentation]. Figure 1 , Figure 1 This is a schematic flowchart of an embodiment of the vehicle submersion method provided in this application, specifically including the following steps S101 to S102.

[0029] Step S101: In response to the vehicle's real-time location being in a water area, detect whether the vehicle's main communication module receives a communication signal sent by the vehicle's slave communication module, wherein the communication signal includes at least one of a heartbeat pulse signal and a tire pressure signal of the vehicle's wheels.

[0030] Aquatic areas can be understood as rivers, lakes, fishponds, reservoirs, and other areas with a risk of drowning. During vehicle operation, the system can acquire the vehicle's real-time location and determine whether the vehicle is in aquatic areas. Once the vehicle's real-time location preliminarily determines that it is in aquatic areas, the system checks whether the communication connection between the main and secondary communication modules remains intact. The main communication module can be the communication module of the vehicle's smart cockpit host, and may include, but is not limited to, wireless communication modules such as Bluetooth, optical communication, or radio frequency communication. The secondary communication module can also include, but is not limited to, wireless communication modules such as Bluetooth, optical communication, or radio frequency communication. The secondary communication module can communicate with the vehicle's tire pressure monitoring module, receiving real-time tire pressure data from the module. Under normal conditions, the main and secondary communication modules are connected, with the main module sending control signals to the secondary module and the secondary module sending heartbeat pulse signals and / or tire pressure signals from the vehicle's wheels to the main module.

[0031] Step S102: If the main communication module does not receive a communication signal within a preset time period, it is determined that the vehicle is in a state of being submerged in water.

[0032] The preset time period can be set according to actual conditions. For example, when it is necessary to improve detection accuracy and timeliness, the duration of the preset time period can be reduced. When the communication module fails to receive a communication signal within the preset time period, it can be determined that the communication module is experiencing a communication failure due to the vehicle being submerged in water, preventing normal communication between it and the main communication module, thus confirming that the vehicle is in a submerged state. For example, the slave communication module can also receive signals from the liquid level detection module. When the liquid level detection module detects that the liquid level has reached a threshold, it can disconnect the communication connection between the main and slave communication modules.

[0033] Through the above implementation method, when it is determined that the vehicle's real-time location is in a water area and the vehicle's main communication module does not receive a communication signal from the slave communication module within a preset time period, it is determined that the vehicle is in a state of being submerged in water. Thus, by combining positioning and communication methods to detect whether the vehicle is in a state of being submerged in water, the accuracy of vehicle submersion detection can be improved in a simple and efficient way.

[0034] Furthermore, after the step of detecting whether the vehicle's main communication module receives the communication signal sent by the vehicle's secondary communication module, the method for determining whether a vehicle has fallen into water also includes: if the main communication module receives the communication signal within a preset time period, it is determined that the vehicle is not in a state of being submerged in water. When it is initially determined that the vehicle is in a water area based on its real-time location, it is then checked whether the communication connection between the secondary and main communication modules is still maintained. If the detection result shows that the main communication module can receive the communication signal within the preset time period, it can be determined that the communication function of the secondary communication module has not failed and can still maintain a normal communication connection with the main communication module, thereby determining that the vehicle is not in a state of being submerged in water.

[0035] In some embodiments, the number of slave communication modules includes multiple modules. The step of determining that the vehicle is not in a submerged state if the master communication module receives a communication signal within a preset time period includes: if the master communication module does not receive a communication signal from any slave communication module within the preset time period, determining that the vehicle is in a submerged state. For example, the vehicle has four wheels, each of which can be independently equipped with a tire pressure monitoring module. Each tire pressure monitoring module is correspondingly equipped with a slave communication module, and each slave communication module can receive tire pressure signals from its corresponding tire pressure monitoring module. Under normal conditions, each slave communication module is communicatively connected to the master communication module, and each master communication module can receive tire pressure signals and / or heartbeat pulse signals from its corresponding slave communication module. If the master communication module does not receive a communication signal from one or more slave modules within the preset time period, it can be determined that the communication function of at least one slave communication module has malfunctioned and cannot communicate normally with the master communication module, thus determining that the vehicle is in a submerged state.

[0036] In some embodiments, the step of detecting whether the vehicle's main communication module receives a communication signal sent by the vehicle's slave communication module in response to the vehicle's real-time location being in a water area includes: in response to the vehicle's real-time location being in a water area, the main communication module sends tire pressure monitoring information to the slave communication module according to a preset time period; and detecting whether the main communication module receives a communication signal including a tire pressure signal from the slave communication module based on the tire pressure monitoring information within a preset time period.

[0037] The preset time period can be set according to actual conditions; for example, the preset time period can be once per second. Under normal conditions, when the vehicle is initially determined to be in a water area based on its real-time location, the main communication module can proactively send tire pressure monitoring information to the slave communication module. After receiving the tire pressure monitoring information, the slave communication module can send the tire pressure monitoring information to the tire pressure monitoring module of its corresponding wheel. This allows the tire pressure monitoring module to monitor the tire pressure of the wheel and obtain the tire pressure signal. The tire pressure monitoring module then transmits the tire pressure signal to the slave communication module, and then to the main communication module. When the main communication module receives the communication signal including the tire pressure signal from the slave communication module based on the tire pressure monitoring information within the preset time period, it can be determined that the communication function of the slave communication module has not failed and can still communicate normally with the main communication module. Therefore, it can be determined that the vehicle is not in a state of being submerged in water. If the main communication module does not receive a communication signal, including the tire pressure signal, from the slave communication module based on tire pressure monitoring information within a preset time period, it can be determined that the communication function of the slave communication module has malfunctioned and cannot communicate normally with the main communication module, thus confirming that the vehicle is in a state of being submerged in water.

[0038] In some embodiments, prior to the step of detecting whether the vehicle's main communication module receives a communication signal sent by the vehicle's secondary communication module in response to the vehicle's real-time location being in a water area, the vehicle falling into water determination method further includes: acquiring the vehicle's current coordinates in real time; mapping the current coordinates to a preset map; and determining whether the vehicle's real-time location is in a water area based on the position of the current coordinates in the preset map.

[0039] During vehicle operation, data can be transmitted from the vehicle's T-BOX Global Navigation Satellite System (GNSS) to the intelligent cockpit host. The intelligent cockpit host decodes the data to obtain the current coordinates with latitude and longitude, then maps these coordinates onto a preset map to determine the vehicle's location. If the location on the preset map corresponds to a water area, the vehicle's real-time location is determined to be in a water area; otherwise, it is determined to be in a non-water area. To further improve detection accuracy, the vehicle's dwell time in a water area can also be detected. If the dwell time exceeds a threshold, it can be preliminarily determined that the vehicle is in a water area.

[0040] See Figure 2 , Figure 2 yes Figure 1 A schematic diagram of an embodiment following step S101. Specifically, see steps S201 to S202.

[0041] Step S201: If the main communication module receives a heartbeat pulse signal within a preset time period, the heartbeat pulse signal is compared with a preset standard pulse signal.

[0042] The main communication module and the slave communication module can simultaneously transmit tire pressure signals and heartbeat pulse signals, meaning that the transmission of heartbeat pulse signals and tire pressure signals share a single communication channel. In this embodiment, to more accurately determine whether the vehicle is submerged, if the main communication module receives a communication signal within a preset time period, it further compares the heartbeat pulse signal in the communication signal with a preset pulse signal, and further determines whether the vehicle is submerged based on the comparison result.

[0043] Step S202: Determine whether the vehicle is in a state of being submerged in water based on the difference between the heartbeat pulse signal and the preset standard pulse signal.

[0044] The preset standard pulse signal can be set according to actual conditions. After comparing the heartbeat pulse signal with the preset standard pulse signal, the degree of difference between the two can be determined. When the difference between the two is large, it can be determined that the received heartbeat pulse signal is abnormal, and thus it can be determined that the vehicle is in a state of being submerged in water. When the difference between the two is small, it can be determined that the received heartbeat pulse signal is normal, and thus it can be determined that the vehicle is not in a state of being submerged in water.

[0045] Furthermore, the step of determining whether a vehicle is in a state of being submerged in water based on the difference between the heartbeat pulse signal and the preset standard pulse signal includes: if the proportion of the high-level signal in the heartbeat pulse signal in a single pulse cycle of the heartbeat pulse signal is less than the proportion of the high-level signal in the standard pulse signal in a single pulse cycle of the standard pulse signal, then the vehicle is determined to be in a state of being submerged in water.

[0046] The single pulse period of the heartbeat pulse signal and the single pulse period of the standard pulse signal can be the same or substantially the same; for example, the single pulse period of both can be, but is not limited to, 1 second or 2 seconds. The single pulse period of the standard pulse signal can simultaneously include a high-level signal and a low-level signal. For example, the duration of a single pulse period is 2 seconds, with the high-level signal and the low-level signal each occupying 1 second within this single pulse period. If the detected high-level signal of the single pulse period of the heartbeat pulse signal is less than 1 second, it can be determined that the vehicle is in a state of being submerged in water; if the detected high-level signal of the single pulse period of the heartbeat pulse signal is greater than or equal to 1 second, it can be determined that the vehicle is not in a state of being submerged in water.

[0047] In summary, when the vehicle's real-time location is determined to be in a water area, and the vehicle's main communication module does not receive a communication signal from the slave communication module within a preset time period, it is determined that the vehicle is in a state of being submerged in water. Thus, by combining positioning and communication methods to detect whether a vehicle is in a state of being submerged in water, the accuracy of vehicle submersion detection can be improved in a simple and efficient way.

[0051] The determination module 32 is used to determine that the vehicle is in a state of being submerged in water if the main communication module does not receive a communication signal within a preset time period.
