[0002] At present, with the increasing number of vehicles, accidents are inevitable during driving, such as vehicles accidentally falling into water, especially at night when vehicles are more likely to have accidents. After the vehicle falls into the water, due to the large overall weight of the vehicle itself, and if all four windows are closed, there is air inside the car and water outside the car. The density of air and water is different, resulting in a pressure difference of about 150 kilograms inside and outside the car.

[0043] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0044] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0045] At present, with the increasing number of vehicles, accidents are inevitable during driving, such as vehicles accidentally falling into water, especially at night when vehicles are more likely to have accidents. After the vehicle falls into the water, due to the large overall weight of the vehicle itself, and if all four windows are closed, there is air inside the car and water outside the car. The density of air and water is different, resulting in a pressure difference of about 150 kilograms inside and outside the car. It is difficult for ordinary people to open the door after the vehicle falls into the water, and the car body is usually not absolutely airtight. Therefore, the body will soon sink with the water, and the internal circuit of the vehicle is prone to short circuit after water enters, and the electric control window and door functions will fail, which will threaten the life safety of passengers in the vehicle.

[0046] The main solution of the embodiment of the present application is: the vehicle is equipped with a posture sensor, and water pressure sensors are arranged at different positions on the body of the vehicle to monitor the posture signal of the posture sensor and the water pressure signal of the water pressure sensor; after determining the tilt direction of the vehicle through the posture signal, obtaining the target water pressure signal of the target water pressure sensor in the tilt direction; determining whether the vehicle has fallen into water based on the target water pressure signal and preset vehicle falling into water judgment conditions; after determining that the vehicle has fallen into water, controlling the vehicle to enter the falling into water mode.

[0047] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or a terminal device capable of realizing the above functions, etc. The following takes the terminal as an example to illustrate this embodiment and the following embodiments.

[0048] Based on this, the embodiment of the present application provides a vehicle safety control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle safety control method of the present application.

[0049] In this embodiment, the vehicle safety control method is applied to a vehicle, the vehicle is equipped with a posture sensor, and water pressure sensors are arranged at different positions on the vehicle body. The vehicle safety control method includes steps S10 to S40:

[0050] Step S10, monitoring the posture signal of the posture sensor and the water pressure signal of the water pressure sensor;

[0051] It should be noted that the above-mentioned vehicle safety control method can be applied to a vehicle (or a controller unit in a vehicle), and a posture sensor can be provided on the vehicle. Accordingly, the posture sensor can be a gyroscope. The installation position of the gyroscope can be set by a technician according to actual needs, and the posture of the vehicle can be detected. In addition, water pressure sensors will be provided at different positions on the vehicle. Water pressure sensors can be provided at the four corners of the outside of the vehicle or at the headlights of the vehicle, and the installation position of the water pressure sensor can also be set by a technician with reference to the above-mentioned position examples, which will not be repeated here. Among them, the water pressure sensor can also be a pressure sensor.

[0052] Exemplarily, the above-mentioned posture sensor and water pressure sensor can be communicatively connected with the vehicle's VCU (Vehic le Control Unit) through the vehicle's CAN network (Controller Area Network), and the water pressure signal of the collected posture signal is sent to the VCU, so that the VCU detects the posture signal and water pressure signal in real time.

[0053] Step S20, after determining the tilt direction of the vehicle through the posture signal, acquiring a target water pressure signal of a target water pressure sensor in the tilt direction;

[0054] It should be noted that after a vehicle actually falls into water, the vehicle body will usually tilt. For example, the location where the vehicle falls into water will usually have a large position difference from the normal driving area of ​​the vehicle, thereby causing the vehicle body to tilt.

[0055] Exemplarily, the attitude signal of the gyroscope can be used to determine whether the vehicle is tilted and the tilt direction after the tilt occurs. After the vehicle tilts, the water pressure sensor in the tilt direction can be used as the target water pressure sensor, and the VCU on the vehicle then obtains the signal collected by the target water pressure sensor, that is, the target water pressure signal. It is understandable that after the vehicle falls into the water, the body of the vehicle tilts, and the water pressure sensors at some positions on the vehicle may not be underwater, or the depths underwater are different, resulting in large differences in the water pressure signals obtained by water pressure sensors at different positions. Therefore, in this embodiment, in order to ensure that the actual wading situation of the vehicle can be determined by the water pressure signal, the water pressure sensor in the tilt direction of the vehicle is selected as the target water pressure sensor, and the target water pressure signal of the target water pressure sensor is used as the basis for subsequent determination of whether the vehicle falls into the water.

[0056] Step S30, determining whether the vehicle falls into water based on the target water pressure signal and a preset vehicle falling into water determination condition;

[0057] Exemplarily, whether the vehicle falls into water is determined by the target water pressure signal and the preset vehicle falling into water judgment condition. The preset vehicle falling into water judgment condition may include a water pressure signal judgment condition, such as a water pressure signal judgment condition that the target water pressure signal is greater than a preset water pressure signal threshold. Correspondingly, if the target water pressure signal exceeds the preset water pressure signal threshold, it can be determined that the vehicle meets the water pressure signal judgment condition, that is, meets the vehicle falling into water judgment condition, thereby determining that the vehicle falls into water. The preset water pressure signal threshold can be obtained by technicians through two scene tests: normal wading of the vehicle and vehicle falling into water. No specific restrictions are made here.

[0058] Step S40, after determining that the vehicle falls into water, controlling the vehicle to enter a water falling mode.

[0059] Exemplarily, after the vehicle's VCU determines that the vehicle has fallen into water through the signals of various sensors, it can control the vehicle to enter the water-falling mode. It is worth noting that after entering the water-falling mode, the vehicle will automatically execute the pre-set emergency measures for falling into water. For example, in order to facilitate the escape of passengers, the vehicle can automatically open the skylight on the roof. At the same time, the vehicle can also send a distress message to the outside through the built-in communication module. The distress message may include the current location of the vehicle, or, in the case of failure of the positioning function, the last recorded location information before sending the distress message. In addition, the emergency measures in the water-falling mode can also be set by technicians according to actual needs.

[0060] In this embodiment, the vehicle is equipped with a posture sensor, and water pressure sensors are arranged at different positions on the vehicle body. The vehicle can monitor the posture signal of the posture sensor and the water pressure signal of the water pressure sensor in real time; after determining the tilt direction of the vehicle through the posture signal, obtain the target water pressure signal of the target water pressure sensor in the tilt direction; determine whether the vehicle falls into the water based on the target water pressure signal and the preset vehicle falling into the water judgment condition; after determining that the vehicle falls into the water, control the vehicle to enter the falling into the water mode. That is, the vehicle will detect the posture signal and the water pressure signal, wherein the posture signal can be used to determine the tilt direction of the vehicle and obtain the target water pressure signal of the target water pressure sensor in the tilt direction. It can be understood that after the vehicle falls into the water, the body tilts, and the water pressure sensors at some positions on the vehicle may not be underwater, or the depths underwater are different, resulting in large differences in the water pressure signals obtained by the water pressure sensors at different positions. Therefore, in this implementation, in order to ensure that the actual wading situation of the vehicle can be determined through the water pressure signal, the water pressure sensor in the clear tilt direction of the vehicle is selected as the target water pressure sensor, and then the target water pressure signal of the target water pressure sensor is combined with the preset vehicle falling into water judgment conditions to determine whether the vehicle has fallen into water, and automatically enter the falling water mode after determining that the vehicle has fallen into water, so as to ensure the safety of the vehicle's occupants and reduce the safety risks after the vehicle falls into water.

[0061] In a feasible implementation manner, the step of controlling the vehicle to enter the water-falling mode includes step S41:

[0062] Step S41, outputting water-falling mode waiting confirmation information, after receiving the confirmation instruction corresponding to the water-falling mode waiting confirmation information, or, if no feedback information corresponding to the water-falling mode waiting confirmation information is received within a preset time period after outputting the water-falling mode waiting confirmation information, the main circuit of the vehicle is turned off, and when the sunroof of the vehicle is closed, the backup power supply of the vehicle is started, and the control motor of the sunroof is driven by the backup power supply to open the sunroof to enter the water-falling mode, wherein the backup power supply is arranged in the roof area of ​​the vehicle.

[0063] It should be noted that in actual applications, after the vehicle is determined to have fallen into water, it can be directly controlled to automatically enter the water-falling mode. In order to ensure the accuracy of the determined water-falling result, the vehicle can also enter the water-falling mode after confirmation.

[0064] For example, after the vehicle determines that it has fallen into the water, it can output the water mode to be confirmed information, such as by outputting a confirmation button corresponding to the water mode to be confirmed information on the vehicle computer, such as Figure 2As shown, the vehicle machine outputs the water-falling mode to be confirmed information popped up on the vehicle machine screen, and the occupants in the vehicle can send a confirmation instruction to the vehicle by clicking the confirmation button. Alternatively, the voice prompt corresponding to the water-falling mode to be confirmed information can be sent to the occupants through the voice interaction system on the vehicle, and accordingly, the occupants can also send a voice confirmation instruction to the vehicle in the form of voice. Accordingly, after receiving the confirmation instruction, the water-falling mode is entered. In addition, after the vehicle falls into the water, it may be unable to interact with the vehicle due to being frightened, such as not noticing the water-falling mode to be confirmed information output by the vehicle. Therefore, if the feedback information corresponding to the water-falling mode to be confirmed information is not received within a preset period after the output of the water-falling mode waiting confirmation information, the water-falling mode can also be directly entered. Correspondingly, the emergency measures corresponding to the water-falling mode may include shutting down the main circuit of the vehicle to avoid the main circuit short-circuiting after the vehicle falls into the water and burning the entire control system of the vehicle. In addition, a backup power supply is also provided on the vehicle, and the backup power supply can be set in the roof area of ​​the vehicle, for example, it can be set at the edge of the vehicle sunroof. Similarly, the control motor supporting the backup power supply can also be set in the roof area. The emergency measures corresponding to the water-fall mode may include, in addition to shutting down the main circuit of the vehicle, driving the control motor of the sunroof through the backup power supply to open the sunroof to facilitate the escape route of the occupants in the vehicle.

[0065] It is understandable that in this embodiment, the backup power supply is set in the roof area, and in general, when a vehicle falls into water, the roof is usually the last place to wade into water, which can ensure that the backup power supply has the longest working time during the falling into water process. In addition, the backup drive motor that controls the sunroof switch is closest to the sunroof, which can effectively reduce costs and reduce opening time.

[0066] In a feasible implementation manner, the main support column on the vehicle is provided with a water-falling airbag, and after the step of starting the backup power supply of the vehicle, the method further includes step S411:

[0067] Step S411, for any target water-falling airbag on the vehicle that has not been popped out, driving the activation motor corresponding to the target water-falling airbag by the backup power supply to activate the gas generator of the target water-falling airbag to pop out the target water-falling airbag.

[0068] It should be noted that the main support columns on the vehicle are also equipped with water-falling airbags, and the main support columns usually refer to the four columns of the vehicle A, B, C, and D. Accordingly, the emergency measures corresponding to the water-falling mode also include popping out the water-falling airbags, thereby providing additional buoyancy for the vehicle that falls into the water, slowing down or preventing the vehicle from sinking.

[0069] For example, for any unpopped target water-falling airbag on the vehicle, the above-mentioned backup power source can be used to drive the activation motor corresponding to the target water-falling airbag, so as to activate the gas generator of the target water-falling airbag through the activation electrode, thereby popping out the target water-falling airbag. The buoyancy of the airbag is used to slow down the sinking speed of the vehicle, or to prevent the vehicle from sinking, so as to buy time for the vehicle occupants to escape.

[0070] like Figure 3 As shown, it is a simplified schematic diagram of the vehicle in this application. Figure 3 As shown, airbags A to D are water-falling airbags arranged on the four pillars of vehicles A, B, C, and D in this application. And the backup power supply is arranged at the edge of the skylight.

[0071] In a feasible implementation manner, before the step of driving the activation motor corresponding to the target water-falling airbag by the backup power supply, the method includes steps S01 to S03:

[0072] Step S01, monitoring the tilt direction of the vehicle;

[0073] Step S02, if the position of the target water-falling airbag matches the tilt direction, executing the step of driving the activation motor corresponding to the target water-falling airbag by the backup power supply;

[0074] Step S03: if the position of the target water-falling airbag does not match the tilt direction, return to the step of monitoring the tilt direction of the vehicle.

[0075] It should be noted that in actual applications, the vehicle body may remain tilted after falling into water. Therefore, in order to ensure the balance of the vehicle body, the vehicle will also monitor the tilt direction of the vehicle in real time, and pop out the airbag according to the tilt direction to raise the tilted part of the vehicle to keep the vehicle balanced.

[0076] Exemplarily, the vehicle can monitor its tilt direction in real time. If the position of the target waterbag matches the tilt direction, such as the target waterbag of the vehicle is located in the tilt direction, it can be considered that the target waterbag matches the tilt direction. In this case, the step of driving the activation motor corresponding to the target waterbag through the backup power supply is performed again. On the contrary, if the position of the target waterbag does not match the tilt direction, the step of monitoring the tilt direction of the vehicle is returned to be performed. That is, if the target waterbag is not in the tilt direction, the tilt direction of the vehicle is continuously monitored until all waterbags of the vehicle are popped out.

[0077] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction and will not be repeated later.

[0078] In this embodiment, the vehicle headlight is provided with a temperature sensor, and the vehicle falling into water determination condition includes a water pressure signal determination condition and a temperature determination condition. On this basis, please refer to Figure 4 The step of determining whether the vehicle falls into water based on the target water pressure signal and the preset vehicle falling into water determination condition comprises S31 to S33:

[0079] Step S31, if the target water pressure signal exceeds a preset water pressure signal threshold, it is determined that the vehicle meets the water pressure signal determination condition;

[0080] Step S32, when the headlight of the vehicle is not turned on, monitoring the temperature signal of the temperature sensor, and determining a first temperature change rate of the headlight according to the temperature signal, and if the first temperature change rate is greater than a preset first temperature change rate threshold, determining that the vehicle meets the temperature determination condition;

[0081] Step S33, after the vehicle satisfies the water pressure signal determination condition and the temperature determination condition, determining that the vehicle falls into water.

[0082] It should be noted that, in the present embodiment, the vehicle headlights are provided with temperature sensors, and accordingly, the water-fall determination conditions include a water pressure signal determination condition and a temperature determination condition.

[0083] Exemplarily, if the target water pressure signal exceeds the preset water pressure signal threshold, the vehicle can determine that it meets the water pressure signal determination condition. And when the headlights of the vehicle are not turned on, the temperature signal of the temperature sensor can be monitored, and the first temperature change rate of the headlights can be determined by the change in the temperature signal. It should be noted that the first temperature change rate refers to the temperature change rate determined when the headlights of the vehicle are not turned on. Accordingly, the first temperature change rate is compared with the preset first temperature change rate threshold. If the first temperature change rate is greater than the preset first temperature change rate threshold, it can be determined that the vehicle meets the temperature determination condition. After determining that the vehicle meets the water pressure signal determination condition and the temperature determination condition, it can be determined that the vehicle has fallen into water.

[0084] It is understandable that if a vehicle accidentally falls into water while driving, the front of the vehicle usually enters the water first. Accordingly, the headlights will quickly enter the water and cool down quickly. Therefore, in this embodiment, the temperature change rate of the headlights is added to the conditions for determining whether the vehicle has fallen into water to ensure the accuracy of the determination result.

[0085] In a feasible implementation manner, a light sensor is provided on the roof of the front side of the vehicle, and the light sensor is used to sense the light intensity in front of the vehicle and generate a light intensity signal. The vehicle falling into water determination condition also includes a light intensity determination condition. After the step of determining that the vehicle meets the water pressure signal determination condition, the method further includes steps S310 to S330:

[0086] Step S310, when the headlight of the vehicle is turned on, monitoring the light intensity signal of the light sensor and the temperature signal of the temperature sensor, and determining the light intensity change rate in real time through the light intensity signal, and determining the second temperature change rate of the headlight through the temperature signal;

[0087] Step S320, if the light intensity change rate is greater than a preset light intensity change rate, it is determined that the vehicle meets the light intensity determination condition, and if the second temperature change rate is greater than a preset second temperature change rate threshold, it is determined that the vehicle meets the temperature determination condition, wherein the preset second temperature change rate threshold is greater than the preset first temperature change rate threshold;

[0088] Step S330, determining that the vehicle falls into water after the vehicle meets the water pressure signal determination condition, the temperature determination condition and the light intensity determination condition.

[0089] It should be noted that, in this embodiment, a light sensor is also provided on the roof of the front side of the vehicle, and the light sensor is used to sense the light intensity in front of the vehicle and generate a corresponding light intensity signal. Accordingly, the vehicle falling into water judgment condition also includes a light intensity judgment condition. For example, when a vehicle accidentally falls into water at night, the light sensor can receive the light beam and light spot from the tilt of the vehicle body, the reflection and refraction of the light from the headlights after it hits the water, so the signal of the light sensor can be used as one of the conditions for falling into water judgment. Figure 3 As shown, the light sensor can be arranged at the roof position on the front side of the vehicle, and the temperature sensor and the water pressure sensor can be arranged at the headlight of the vehicle.

[0090] Exemplarily, if the headlights of the vehicle are turned on, the light intensity signal of the light sensor and the temperature signal of the temperature sensor are monitored simultaneously. Then the light intensity change rate, that is, the amount of light intensity change per unit time, is determined in real time through the light intensity signal. And the second temperature change rate of the headlight is determined through the temperature signal, and the second temperature change rate represents the temperature change rate of the headlight when the headlight is turned on. Correspondingly, if the light intensity change rate is greater than the preset light intensity change rate, it is determined that the vehicle meets the light intensity determination condition. If the second temperature change rate is greater than the preset second temperature change rate threshold, it is determined that the vehicle meets the temperature determination condition. It is worth noting that the preset second temperature change rate threshold is greater than the above-mentioned preset first temperature change rate threshold. That is, since the temperature of the headlights of the vehicle is relatively high when it is turned on, the temperature change of the headlights will more easily reach the first temperature change rate. Therefore, in this embodiment, if the headlights of the vehicle are turned on, the temperature change will be compared with the higher preset second temperature change rate threshold to ensure the accuracy of the vehicle falling into water determination result. After the vehicle meets the water pressure signal determination condition, the temperature determination condition and the light intensity determination condition, it can be determined that the vehicle falls into water. It can be understood that, in this embodiment, a series of state changes that may be caused by a vehicle falling into water are added as the judgment conditions for falling into water, so as to ensure the accuracy of the judgment result of falling into water.

[0091] In addition, refer to Figure 5 This is a schematic diagram of the overall framework of the vehicle falling into water mode in this application.
