Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by those of ordinary skill in the art without making creative work are within the scope of protection of the present application.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

[0025] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "set", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or connected through an intermediate medium. For ordinary technicians in this field, the above-mentioned specific meanings belonging to this application can be connected according to specific circumstances.

[0026] With the rapid development of the automobile industry, cars have become one of the indispensable means of transportation for people to travel. The number of cars has increased year by year, and more and more people have private cars. The popularity of cars has brought development to the manufacturing and design of auto parts.

[0027] However, there are many unpredictable situations in the process of driving. For example, if an emergency occurs during driving, it is necessary to promptly and accurately determine the predicament of the vehicle so as to quickly respond correctly. For example, if a vehicle falls into a water area during driving and the current status of the vehicle cannot be accurately and efficiently monitored through a specific monitoring method, it is easy to cause serious consequences due to untimely information transmission.

[0028] In order to solve the technical problems existing in the related art, the present application provides a vehicle falling into water method, see Figure 1 , Figure 1 It is a flow chart of an embodiment of the method for a vehicle falling into water provided by the present application, specifically, it includes the following steps S101 to S102.

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

[0030] Water areas can be understood as areas with drowning risks such as rivers, lakes, fish ponds, reservoirs, etc. The vehicle can obtain the real-time position of the vehicle during driving, and then determine whether the vehicle is in a water area based on the real-time position. When the vehicle is initially determined to be in a water area based on the real-time position of the vehicle, it is detected whether the communication connection between the slave communication module and the main communication module is still maintained. Among them, the main communication module can be a communication module of the vehicle's smart cockpit host, for example, the main communication module can include but is not limited to wireless communication modules such as Bluetooth modules, optical communication modules or radio frequency communications. The slave communication module can also include but is not limited to wireless communication modules such as Bluetooth modules, optical communication modules or radio frequency communications. The slave communication module can be connected to the tire pressure monitoring module of the vehicle in communication, and the slave communication module can receive the tire pressure data of the vehicle monitored by the tire pressure monitoring module in real time. Under normal conditions, the main communication module and the slave communication module are in a communication connection state, and the main communication module can send control signals to the slave communication module, etc., and the slave communication module can send heartbeat pulse signals and / or tire pressure signals of vehicle wheels to the main communication 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 water-falling state.

[0032] The preset time period can be set according to the actual situation. For example, when it is necessary to improve the detection accuracy and timeliness of the detection, the length of the preset time period can be reduced. When it is detected that the communication module does not receive the communication signal in the preset time period, it can be determined that the communication function of the slave communication module fails due to the vehicle wading, and it is unable to communicate normally with the main communication module, and then it can be determined that the vehicle is in a state of falling into the water. For example, the slave communication module can also receive a liquid level detection module. When the liquid level detection module detects that the liquid level height reaches a threshold, the communication connection between the main communication module and the slave communication module can be disconnected.

[0033] Through the above-mentioned implementation, when it is determined that the real-time position of the vehicle is in a water area and the main communication module of the vehicle does not receive the communication signal from the slave communication module within a preset time period, it is determined that the vehicle is in a water state. Therefore, by combining positioning and communication to jointly detect whether the vehicle is in a water state, the accuracy of vehicle water fall detection can be improved in a simple and efficient way.

[0034] Furthermore, after the step of detecting whether the main communication module of the vehicle receives the communication signal sent by the slave communication module of the vehicle, the method for determining that the vehicle has fallen into water further includes: if the main communication module receives the communication signal within a preset time period, determining that the vehicle is not in a state of falling into water. When it is preliminarily determined that the vehicle is in a water area based on the real-time position of the vehicle, it is detected whether the slave communication module and the main communication module are still in communication connection. 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 slave communication module has not failed and can still communicate and connect normally with the main communication module, and then it can be determined that the vehicle is not in a state of falling into water.

[0035] In some embodiments, the number of slave communication modules includes multiple, if the main communication module receives a communication signal within a preset time period, the step of determining that the vehicle is not in a state of falling into water includes: if the main communication module does not receive a communication signal sent by any slave communication module within a preset time period, it is determined that the vehicle is in a state of falling into water. Exemplarily, the vehicle includes four wheels, each wheel can be independently configured with a tire pressure monitoring module, each tire pressure monitoring module is correspondingly configured with a slave communication module, and the slave communication module can receive the tire pressure signal of the wheel monitored by the corresponding tire pressure monitoring module. Under normal conditions, each slave communication module is connected to the main communication module for communication, and each main communication module can receive tire pressure signals and / or heartbeat pulse signals from the corresponding slave communication modules. If the main communication module does not receive a communication signal sent by one or more slave communication modules within a preset time period, it can be determined that the communication function of at least one slave communication module fails and cannot be normally connected to the main communication module for communication, and then it can be determined that the vehicle is in a state of falling into water.

[0036] In some embodiments, in response to the real-time position of the vehicle being in a water area, the step of detecting whether the main communication module of the vehicle receives the communication signal sent by the slave communication module of the vehicle includes: in response to the real-time position of the vehicle 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; 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 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 every 1 second, etc. Under normal conditions, when it is preliminarily determined that the vehicle is in a water area based on the real-time position of the vehicle, the main communication module can give priority to actively sending tire pressure monitoring information to the slave communication module, and the slave communication module can send the tire pressure monitoring information to the tire pressure monitoring modules of the corresponding wheels after receiving the tire pressure monitoring information, so that the tire pressure monitoring module can monitor the tire pressure of the wheel according to the tire pressure monitoring information to obtain a tire pressure signal, and the tire pressure monitoring module then transmits the tire pressure signal to the slave communication module, and then transmits it to the main communication module through the slave communication module. When the main communication module receives a communication signal including a tire pressure signal fed back by the slave communication module based on the tire pressure monitoring information within a preset time period, it can be determined that the communication function of the slave communication module has not failed, and it can still communicate normally with the main communication module, and then it can be determined that the vehicle is not in a water state. When the main communication module does not receive the communication signal including the tire pressure signal from the slave communication module based on the tire pressure monitoring information feedback within the preset time period, it can be determined that the communication function of the slave communication module has failed and cannot communicate normally with the main communication module, and it can be determined that the vehicle is in a water state.

[0038] In some embodiments, before the step of detecting whether the main communication module of the vehicle receives the communication signal sent by the slave communication module of the vehicle in response to the real-time position of the vehicle being in a water area, the method for determining whether the vehicle falls into water also includes: acquiring the current coordinates of the vehicle in real time; mapping the current coordinates to a preset map, and determining whether the real-time position of the vehicle is in a water area based on the position of the current coordinates in the preset map.

[0039] During the driving process of the vehicle, the global navigation satellite system (GNSS) of the vehicle T-BOX can be used to send data to the smart cockpit host. After decoding the data, the smart cockpit host obtains the current coordinates with longitude and latitude, and then maps the current coordinates to the preset map to obtain the position of the current coordinates in the preset map. If the current coordinates correspond to the position in the preset map as a water area, it can be determined that the real-time position of the vehicle is in the water area, otherwise it is determined that the real-time position of the vehicle is in a non-water area. In order to further improve the accuracy of detection, the residence time of the vehicle in the water area can also be detected. If the residence time exceeds the threshold, it can be preliminarily determined that the vehicle is in the water area.

[0040] See also Figure 2 , Figure 2 yes Figure 1 Specifically, refer to step S201 to step 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 tire pressure signal and the heartbeat pulse signal can be transmitted simultaneously between the master communication module and the slave communication module, that is, the transmission of the heartbeat pulse signal and the transmission of the tire pressure signal share a communication channel. In this embodiment, in order to more accurately determine whether the vehicle is in a water state, if the master communication module can receive the communication signal within a preset time period, it is necessary to further compare the heartbeat pulse signal in the communication signal with the preset pulse signal, and further determine whether the vehicle is in a water state based on the comparison result.

[0043] Step S202: Determine whether the vehicle is in a water-falling state 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 the actual situation. After the heartbeat pulse signal and the preset standard pulse signal are compared, the 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 then it can be determined that the vehicle is in a state of falling into the water. When the difference between the two is small, it can be determined that the received heartbeat pulse signal is normal, and then it can be determined that the vehicle is not in a state of falling into the water.

[0045] Furthermore, based on the difference between the heartbeat pulse signal and the preset standard pulse signal, the step of determining whether the vehicle is in a state of falling into water includes: if the proportion of the high-level signal in the heartbeat pulse signal in a single pulse period of the heartbeat pulse signal is less than the proportion of the high-level signal in the standard pulse signal in a single pulse period of the standard pulse signal, it is determined that the vehicle is in a state of falling into 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 periods of both can include but are not limited to 1 second or 2 seconds, etc. In a single pulse period of the standard pulse signal, a high-level signal and a low-level signal can be included at the same time. Exemplarily, the time of a single pulse period is 2 seconds, and the high-level signal and the low-level signal occupy 1 second respectively in the single pulse period. At this time, if the high-level signal of a single pulse period of the heartbeat pulse signal is detected to be less than 1 second, it can be determined that the vehicle is in a state of falling into the water. If the high-level signal of a single pulse period of the heartbeat pulse signal is detected to be higher than or equal to 1 second, it can be determined that the vehicle is in a state of not falling into the water.

[0047] To sum up, when it is determined that the real-time position of the vehicle is in a water area and the main communication module of the vehicle has not received the communication signal from the slave communication module within a preset time period, it is determined that the vehicle is in a water state. Therefore, by combining positioning and communication to jointly detect whether the vehicle is in a water state, the accuracy of vehicle water fall 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 water-falling state if the main communication module does not receive a communication signal within a preset time period.
