[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the present application will be described clearly and completely below in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0038] In conjunction with Figure 1 The embodiments of the present application provide a vehicle water-encountering danger remote danger-avoiding and trouble-escaping control method. Through intelligent means, the vehicle can take timely danger-avoiding measures when encountering water-encountering crisis, so as to reduce or avoid vehicle damage. The method specifically includes the following steps:

[0039] S1, judging whether the water-encountering depth of the vehicle exceeds a set water-encountering depth threshold value, if yes, entering S2, if no, continuously judging this condition.

[0040] Specifically, the vehicle is equipped with a high-precision water level sensor 1, which is installed at the bottom or near the bottom of the vehicle to ensure that the current water-encountering depth of the vehicle can be accurately measured. The water level sensor 1 is connected with the main control unit (ECU) of the vehicle, and transmits water level data to the ECU in real time. The ECU has a pre-set water-encountering depth threshold value, and it needs to be explained that the water-encountering depth threshold value is determined comprehensively according to the type of the vehicle, the height of the chassis, the sealing performance and other factors. The ECU continuously receives and processes the water level data from the water level sensor 1, and once it is detected that the water-encountering depth exceeds the pre-set water-encountering depth threshold value, the next operation is triggered immediately.

[0041] S2, controlling the air spring of the vehicle to rise to the highest position, and sending a vehicle water-encountering risk warning signal to the vehicle owner's mobile terminal.

[0042] Specifically, after confirming that the water-encountering depth of the vehicle exceeds the standard, the ECU quickly sends an instruction to the air suspension system of the vehicle to control the air spring to inflate to its maximum stroke, so as to increase the vehicle's ground clearance, reduce the contact depth of the vehicle's bottom with the accumulated water, and reduce the risk of water flooding. At the same time, the ECU sends an emergency notification to the mobile terminal (such as a smart phone, a smart watch, etc.) previously bound by the vehicle owner through the wireless communication module (such as 4G / 5G, Bluetooth or Wi-Fi) of the vehicle, including the water-encountering depth of the vehicle, the location information and the suggested action, reminding the vehicle owner to pay attention and take corresponding measures.

[0043] S3, receiving the decision signal fed back by the owner mobile terminal, the decision signal including a remote start vehicle intelligent driving away signal or a float airbag 2 detonation signal.

[0044] Specifically, after receiving the wading risk warning, the owner can make a decision and send a feedback signal to the vehicle through a special APP on the mobile terminal or a short message reply, etc. The decision signal is divided into two types: one is the remote start vehicle intelligent driving away signal, that is, the owner authorizes the vehicle to automatically execute the risk avoidance driving route and try to drive away from the wading area; the second is the float airbag 2 detonation signal, which is suitable for the case that the owner thinks that the vehicle cannot safely drive away and needs to immediately use emergency protection measures.

[0045] S4, in response to the decision signal, controlling the vehicle to drive away from the wading area or detonate the float airbag 2, the float airbag 2 being arranged at the bottom of the vehicle body.

[0046] That is, in response to the decision signal, there are two modes, namely the intelligent driving away mode and the float airbag 2 detonation mode.

[0047] Regarding the intelligent driving away mode, after receiving the remote start vehicle intelligent driving away signal, the ECU activates the automatic driving system of the vehicle and automatically controls the vehicle to drive along the risk avoidance driving route until it leaves the wading danger area. Preferably, during this period, the vehicle will maintain communication with the owner's mobile terminal and report the driving state and position in real time.

[0048] Regarding the float airbag 2 detonation mode, if the float airbag 2 is selected to be detonated, the ECU immediately sends a detonation instruction to the float airbag 2 system installed at the bottom of the vehicle body. The float airbag 2 inflates quickly to provide additional buoyancy for the vehicle, prevent the vehicle from sinking completely, keep the vehicle stable and floating, and avoid damage to the key electrical equipment of the vehicle due to water flooding.

[0049] Through the above implementation, the self-protection ability of the vehicle in extreme weather conditions is effectively improved, a remote risk avoidance solution is provided for the owner, and the loss caused by wading of the vehicle is minimized.

[0050] In one implementation, before determining whether the vehicle wading depth exceeds the set depth threshold, the method further includes:

[0051] Obtaining the vehicle wading depth, the vehicle wading depth being collected by each water level sensor 1 arranged at the bottom of the vehicle body and close to each wheel position.

[0052] That is, before formally entering the wading depth judgment process, the real-time wading depth of the vehicle is first obtained through a series of water level sensors 1. The water level sensors 1 are arranged at the bottom of the vehicle body and close to each wheel to ensure that the wading conditions of the vehicle in different areas can be fully and accurately reflected.

[0053] As shown in Figure 3a and 3b , d (1≤d≤4) water level sensors 1 are arranged at the bottom of the vehicle body and close to each wheel. When the vehicle is in an off state, the water level sensors 1 start to work and accurately identify the water depth of the wading road surface in real time. The accuracy of the water level sensors 1 can reach 100%, ensuring that the collected data is reliable and effective. In combination with Figure 2a , 2b and 2c, a wading depth threshold a is preset, which can be set in the range of 200mm~1000mm according to factors such as vehicle type and road conditions. When the wading depth of the vehicle monitored by the water level sensors 1 exceeds the set wading depth threshold a, the water level sensors 1 send a network wake-up signal. The network wake-up signal is used to wake up the CIC chassis domain control and the TBOX remote / vehicle communication module of the vehicle, and the collected wading depth is sent to these two modules at the same time. After receiving the network wake-up signal and the wading depth, the CIC chassis domain control is woken up and enters the working state. At this time, the chassis domain control sends instructions to the air spring controller to control the air spring to rise to the highest position, so as to increase the ground clearance of the vehicle and avoid the vehicle being submerged due to wading too deep. At the same time of the response of the chassis domain control, the TBOX remote / vehicle communication module also starts to work, ready to receive and execute subsequent remote risk avoidance instructions.

[0054] Preferably, the water level sensors 1 collect data in an alternating sleep and work mode, and the sleep time and the work time are 1s~10s respectively. That is, in order to reduce the static current loss of the vehicle, an optimized water level sensor 1 working mode is adopted, that is, the sleep and work are alternated. After the vehicle is turned off and parked, the water level sensors 1 enter a cycle sleep and work state. Specifically, the water level sensors 1 wake up automatically after a period of sleep (sleep time M, adjustable in the range of 1s~10s), and collect data for a period of time (work time L, also adjustable in the range of 1s~10s), and then enter the sleep state again. This intermittent working mode not only ensures that the water level sensors 1 can respond to water level changes in time, but also effectively controls the static current loss.

[0055] Preferably, the water level sensors 1 are powered by the vehicle battery; when the SOC of the vehicle battery is less than a set power threshold, the vehicle power battery is controlled to charge the vehicle battery.

[0056] That is, the water level sensor 1 is powered by the vehicle battery. For example, the vehicle battery provides KL30 electricity (i.e. always on, not controlled by the ignition switch), ensuring that the water level sensor 1 can still work normally after the vehicle is turned off and parked. This power supply mode ensures the reliability of the water level sensor 1 in critical situations. An EBS battery sensor is used to monitor the remaining power (SOC) of the vehicle battery in real time. The EBS battery sensor can accurately measure the power state of the vehicle battery and transmit data to the ECU in real time. When the SOC of the battery is lower than the set power threshold c% (c can be set to a specific value within the range of 5%~50%, the specific value is determined according to the vehicle model and use scenario), the EBS battery sensor sends a request for power signal to the power battery BMS (battery management system). After receiving the signal, the BMS determines whether the power state of the power battery allows power compensation. If the power battery has sufficient power and allows power compensation, the BMS controls the CDU (integrated OBC & DCDC module) to realize the power compensation function of the battery. The OBC (on-board charger) in the CDU is responsible for converting external alternating current into direct current, while the DCDC module is responsible for converting high-voltage direct current from the power battery into low-voltage direct current suitable for the vehicle battery. During the power compensation process, the CDU accurately controls the charging current and voltage to ensure safe charging of the battery. When the SOC of the battery reaches a safe level, the BMS stops the power compensation operation through the CDU. At the same time, the EBS battery sensor continues to monitor the SOC of the battery in order to trigger the power compensation process again when needed.

[0057] In an implementation manner, when the vehicle water risk warning signal is sent to the vehicle owner mobile terminal, the vehicle sentinel mode is started, and the vehicle owner mobile terminal is sent the vehicle surrounding environment condition monitored by the sentinel mode; the decision signal is determined by the vehicle surrounding environment condition, if the vehicle surrounding environment condition meets the vehicle driving off condition, the decision signal is the remote start vehicle intelligent driving off signal; if the vehicle surrounding environment condition does not meet the vehicle driving off condition, the decision signal is the float water airbag 2 detonation signal.

[0058] Specifically, while sending the water risk warning signal, the ECU starts the vehicle sentry mode. It should be understood that the sentry mode is a vehicle safety monitoring function that can monitor the vehicle's surrounding environment in real time, including multimedia information such as video and audio. The sentry mode transmits the monitored vehicle surrounding environment condition data to the vehicle cloud interconnection APP of the owner's mobile terminal in real time. The owner can remotely view the water situation, road conditions and other potential obstacles around the vehicle through the APP. The owner decides whether to execute the function of automatically starting the vehicle to avoid danger and drive away from the water area according to the vehicle surrounding environment condition monitored by the sentry mode. If the vehicle surrounding environment condition meets the vehicle driving away condition (such as unobstructed road, no other obstacles, etc.), the owner can choose to remotely start the vehicle intelligent driving away signal. The owner sends the remote start signal to the ECU through the vehicle cloud interconnection APP. After receiving the signal, the ECU activates the automatic driving system of the vehicle, plans a safe escape path and automatically controls the vehicle to drive to a safe area. If the vehicle surrounding environment condition does not meet the vehicle driving away condition (such as the road is flooded, there are other obstacles, etc.), the owner can choose to send the water balloon 2 detonation signal. The owner sends the detonation signal to the ECU through the vehicle cloud interconnection APP. After receiving the detonation signal, the ECU immediately sends the detonation instruction to the water balloon 2 system. After receiving the instruction, the water balloon 2 inflates quickly to provide additional buoyancy for the vehicle to avoid sinking.

[0059] Preferably, the remote vehicle intelligent driving away signal comprises a driving away route; if the vehicle surrounding environment condition meets the vehicle driving away condition, the vehicle intelligent driving away from the water area is controlled according to the driving away route.

[0060] Specifically, the owner decides whether to execute the function of automatically avoiding danger and driving away from the water area according to the vehicle surrounding environment condition monitored by the sentry mode. If it is decided to execute, the owner plans the escape route through the mobile interconnection APP and sends the remote vehicle ignition instruction and the vehicle automatic avoidance driving away from the water area instruction.

[0061] For example, the remote vehicle ignition instruction and the vehicle automatic risk-avoiding driving-off the water-involved site instruction issued by the vehicle owner through the mobile phone interconnection APP are received by the vehicle networking TSP (vehicle cloud interconnection) and forwarded to the TBOX remote / vehicle-mounted communication module. The TBOX sends the instruction to the VCU vehicle control unit, and the VCU sends the high-voltage signal and the vehicle power-on start signal to complete the remote start of the vehicle. After receiving the vehicle automatic risk-avoiding driving-off the water-involved site instruction, the ADCC intelligent driving calculation center controls the vehicle to automatically drive off the water-involved site according to the route planned by the vehicle owner on the mobile phone interconnection APP. During driving, the ADCC intelligent driving calculation center continuously monitors the vehicle state and the surrounding environment to ensure safe risk avoidance. When the vehicle safely drives off the water-involved site according to the planned route, the ADCC intelligent driving calculation center controls the vehicle to slow down and park, and notifies the ECU that the vehicle risk-avoiding operation is completed. After receiving the notification that the risk-avoiding operation is completed, the ECU controls the vehicle to power off, and ends the risk-avoiding operation.

[0062] Through the above embodiments, the present application not only improves the self-protection ability of the vehicle in the water-involved dangerous situation, but also provides an intelligent solution for the vehicle owner to remotely avoid risks and get out of trouble. At the same time, through the real-time monitoring of the sentinel mode, the intelligent path planning and the automatic driving risk-avoiding function, the reliability of the risk-avoiding operation is further enhanced.

[0063] It should be noted that in the above embodiments, the present application is combined with Figure 4a and 4b As shown, the floating water air bag 2 is fixed under the vehicle body chassis by F (4≤F≤20) bolts or buckles, without the need to develop a vehicle body chassis protection plate. The floating water air bag 2 can play the role of the vehicle body chassis protection plate. After the floating water air bag 2 is opened, the vehicle is driven off the water-involved site, and the floating water air bag 2 can be repaired and reused.
