[0045] It should be understood that the specific embodiments described here are only used to explain the technical solutions of the application, and are not used to limit the application.

[0046] In order to better understand the technical solutions of the application, the following will be described in detail with reference to the drawings and specific embodiments in the specification.

[0047] The main solution of the embodiment of the application is: when the current state of the target vehicle is a target water-falling state, the running state of the door lock is acquired; when the running state of the door lock is a locking state, a door unlocking signal is generated; the door lock of the target vehicle is unlocked according to the door unlocking signal, and the door of the target vehicle is opened according to the target opening force duty ratio of the driving mechanism.

[0048] At present, more and more electric suction and release door handles and hidden door handles are configured in new energy vehicles. Due to some factors, the hidden handle cannot be popped out or stuck, the door is not easy to open from the outside, the rescue time is affected, and serious water-falling personnel casualty events are caused. At present, only the window glass can be opened when the vehicle falls into water, and the personnel needs to climb out of the glass. If the vice driver or the rear passenger is not easy to move, it is difficult to escape.

[0049] The application determines the running state of the door lock when the target vehicle is in the water-falling state, controls the door lock to be unlocked according to the door unlocking signal when the running state of the door lock is the locking state, and controls the door to be opened according to the target opening force duty ratio of the driving mechanism, so that the electric door can be immediately and automatically opened without additional switch signal input when falling into water, and the personnel can quickly evacuate the vehicle, thereby avoiding the risk that the door cannot be opened due to water pressure and reducing personnel casualties.

[0050] It should be noted that the execution subject of the 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 an electronic device, a door unlocking device, etc. capable of realizing the above functions. The door unlocking device is taken as an example to illustrate the embodiment and the following embodiments.

[0051] Based on this, the application provides a door unlocking method, which is described below with reference to Figure 1 , Figure 1 The flowchart of the first embodiment of the door unlocking method of the application is shown in the figure.

[0052] In the embodiment, the method includes steps S10-S30:

[0053] Step S10, when the current state of the target vehicle is a target water-falling state, the running state of the door lock is acquired;

[0054] It should be noted that the target vehicle is integrated with a door assembly, an electric door driving mechanism, an electric door controller, a collision acceleration sensor, a vehicle slope sensor and a water pressure sensor. In the embodiment, the water pressure sensor can be designed on the plastic part of the door, and the design height is h1, which can be set to less than 800-1000 mm from the ground, or other values, which are not limited in the embodiment.

[0055] It can be understood that the data collected by the collision acceleration sensor, the vehicle slope sensor and the water pressure sensor are used to determine the current state of the target vehicle, and when the data collected by the three satisfies the falling into water condition, it is determined that the target vehicle has a falling into water event, and the current state of the target vehicle is a target falling into water state.

[0056] In a specific implementation, when the BCM (Body Control Module, vehicle body controller) identifies that the target vehicle is in the target falling into water state, the BCM acquires the running state of the door lock, which includes the central control state and the child lock state, and the door lock includes the central control lock and the child lock.

[0057] Step S20, when the running state of the door lock is in the locked state, a door unlocking signal is generated;

[0058] It should be noted that when the child lock state is in the locked state, or the central control state is in the locked state, or both are in the locked state, the running state of the door lock is in the locked state. When the running state of the door lock is in the locked state, the door unlocking signal is generated.

[0059] Step S30, according to the door unlocking signal, the door lock of the target vehicle is unlocked, and according to the target opening force duty ratio of the driving mechanism, the door of the target vehicle is opened.

[0060] It should be noted that according to the door unlocking signal, the door lock of the target vehicle is unlocked, and the BCM sends a falling into water signal to the electric door controller, and the electric door controller controls the opening force duty ratio of the electric door driving mechanism to adjust to the target opening force duty ratio. In the embodiment, the target opening force duty ratio of the electric door driving mechanism is a set value, and in general cases, the opening force of the driving mechanism is 30N, and the opening force duty ratio is about 1 / 15 to open the door, and in the embodiment, the target opening force duty ratio is set to 0%, and the opening force is increased to the extreme value of 500N.

[0061] It can be understood that the electric door driving mechanism controls the opening of the door of the target vehicle according to the target opening force duty ratio, without additional switch signal input to unlock the door.

[0062] In an embodiment, in step S30, controlling the door opening of the target vehicle according to the target opening force duty ratio of the driving mechanism can further include steps A11-A12:

[0063] In step A11, the target opening force duty ratio of the driving mechanism, the stopper opening force, and the unlocking time window are determined according to the door unlocking strategy.

[0064] In step A12, the door opening of the target vehicle is controlled according to the target opening force duty ratio, the stopper opening force, and the unlocking time window.

[0065] It should be noted that the door unlocking strategy is a set door unlocking mode when the vehicle falls into water, and in this embodiment, the door unlocking strategy includes adjusting the opening force duty ratio of the electric door driving mechanism to the target opening force duty ratio, allowing the electric stopper to provide a 150N opening force, and increasing the door unlocking time window. In this embodiment, the opening force provided by the electric stopper is the stopper opening force.

[0066] It can be understood that the electric door driving mechanism and the electric stopper continuously provide the opening force, and the length of time that the door remains in the unlocked state is extended to cope with the internal and external pressure difference. Specifically, when the electric door controller determines that the target vehicle falls into water, the opening force duty ratio of the electric door driving mechanism is adjusted to 0%, the opening force is increased to an extreme value of 500N, and at the same time, the electric stopper provides a 150N opening force, which forcibly opens the door of the target vehicle to a predetermined angle. In this state, the door unlocking time window is adjusted at the same time, the length of time that the door remains in the unlocked state is extended, and the electric driving mechanism and the stopper continuously provide the opening force to cope with the internal and external pressure difference.

[0067] In this embodiment, the target opening force duty ratio of the driving mechanism, the stopper opening force, and the unlocking time window are determined according to the door unlocking strategy, and the door opening of the target vehicle is controlled according to the target opening force duty ratio, the stopper opening force, and the unlocking time window. Through the above-mentioned manner, the door can be quickly unlocked without additional switch signal input, so that the driver and passenger can push the door open and then quickly evacuate the vehicle.

[0068] The above is only one of the embodiments of step S30 provided by the present embodiment, in which the door opening of the target vehicle is controlled according to the target opening force duty ratio of the driving mechanism. The present embodiment is not limited to the specific implementation of step S30.

[0069] In an embodiment, after step S30, steps B11-B13 can be further included.

[0070] In step B11, the current state of the safety belt of the target vehicle is detected.

[0071] Step B12, generating a seat belt unlocking signal when the seat belt current state is the locking state;

[0072] Step B13, controlling the seat belt of the target vehicle to be opened based on the seat belt unlocking signal.

[0073] It should be noted that after determining that the target vehicle is in the target falling into water state, the seat belt current state of the target vehicle is obtained in time. The seat belt current state can reflect whether each seat belt of the target vehicle is in the locking state. When the seat belt current state is the locking state, it indicates that the seat belt of the target vehicle is locked. At this time, the seat belt unlocking signal is generated, and the seat belt of the target vehicle that is locked is controlled to be opened based on the seat belt unlocking signal.

[0074] In this embodiment, the seat belt current state of the target vehicle is detected. When the seat belt current state is the locking state, the seat belt unlocking signal is generated. The seat belt of the target vehicle is controlled to be opened based on the seat belt unlocking signal. Through the above manner, the driver and passenger of the target vehicle can quickly evacuate.

[0075] In a possible implementation, after step S30, steps C11-C12 can be further included.

[0076] Step C11, generating a car light control signal and a falling into water alarm information based on the target falling into water state;

[0077] Step C12, controlling the car light of the target vehicle to be turned on based on the car light control signal, and sending the falling into water alarm information to a terminal of a rescuer.

[0078] It should be noted that when it is determined that the target vehicle is in the target falling into water state, the car light control signal and the falling into water alarm signal are generated based on the target falling into water state. The car light control signal is sent to the interior light of the vehicle, and the interior light of the target vehicle is controlled to be turned on to increase the interior lighting and warning of the vehicle.

[0079] It can be understood that the falling into water alarm information includes the falling into water time and the falling into water address. The falling into water alarm information is sent to the terminal of the rescuer, so that the rescuer can timely know the related information of the target vehicle falling into water and timely take rescue measures. In this embodiment, the rescuer can be set as a firefighter, or can be set as an emergency contact person set by the user.

[0080] In this embodiment, the car light control signal and the falling into water alarm information are generated based on the target falling into water state. The car light of the target vehicle is controlled to be turned on based on the car light control signal, and the falling into water alarm information is sent to the terminal of the rescuer. Through the above manner, the safety of the vehicle is further improved.

[0081] The embodiment provides a vehicle door unlocking method, and the method of the embodiment acquires a door lock running state when a current state of a target vehicle is a target falling-into-water state; generates a vehicle door unlocking signal when the door lock running state is a locking state; controls the door lock of the target vehicle to be unlocked according to the vehicle door unlocking signal, and controls the door of the target vehicle to be opened according to a target opening force duty ratio of a driving mechanism. In the foregoing manner, when the target vehicle is determined to be in a falling-into-water state, the door lock running state is determined, and when the door lock running state is a locking state, the door lock is controlled to be unlocked according to the vehicle door unlocking signal, and the door is controlled to be opened according to the target opening force duty ratio of the driving mechanism, so that the electric vehicle door can be immediately and automatically opened when falling into water without additional switch signal input, and then personnel can quickly evacuate the vehicle, the risk that the door cannot be opened due to water pressure is avoided, and personnel casualties are reduced.

[0082] Based on the first embodiment of the application, in the second embodiment of the application, the same or similar contents as the above-mentioned first embodiment can be referred to the above introduction, and the subsequent will not be described in detail. On this basis, please refer to Figure 2 , before step S10, the vehicle door unlocking method further includes steps S11-S14:

[0083] Step S11, determining a current pressure value according to water pressure data collected by a water pressure sensor;

[0084] Step S12, determining a current vehicle slope according to slope data collected by a slope sensor;

[0085] Step S13, determining a current acceleration according to acceleration data collected by a collision acceleration sensor;

[0086] Step S14, judging a state according to the current pressure value, the current vehicle slope and the current acceleration to determine a current state of the target vehicle.

[0087] It should be noted that the target vehicle is integrated with a vehicle door assembly, an electric vehicle door driving mechanism, an electric vehicle door controller, a collision acceleration sensor, a vehicle slope sensor and a water pressure sensor. In the embodiment, the water pressure sensor can be designed on a vehicle door plastic part, and the design height is h1, which can be set to less than 800-1000mm from the ground, or other values, which are not limited in the embodiment.

[0088] It can be understood that the current pressure value of the target vehicle is determined in real time according to the water pressure data collected by the water pressure sensor; the current vehicle slope of the target vehicle is determined in real time according to the slope data collected by the slope sensor; and the current acceleration of the target vehicle is determined in real time according to the acceleration data collected by the collision acceleration sensor. The current pressure value, the current vehicle slope and the current acceleration of the target vehicle are combined to determine the current state of the target vehicle.

[0089] In a possible implementation, the step S14 can further include steps D11-D14.

[0090] In step D11, when the current pressure value is greater than a preset pressure threshold, slope detection is performed according to the current vehicle slope and a preset slope range.

[0091] It should be noted that the preset pressure threshold refers to a preset pressure threshold value. When the current pressure value is greater than the preset pressure threshold, it indicates that the target vehicle has a risk of falling into water. At this time, slope detection is performed according to the current vehicle slope and the preset slope range to determine whether the current vehicle slope is within the preset slope range. In this embodiment, the preset pressure threshold can be set to ρgh1, where h1 is the design height of the water pressure sensor on the target vehicle. The preset slope range is a preset slope range corresponding to the vehicle inclination. When the target vehicle is in an emergency falling into water or an emergency being flooded, the vehicle head will be inclined, and the current vehicle slope will be within the preset slope range.

[0092] In step D12, when the current vehicle slope is within the preset slope range, acceleration detection is performed according to the current acceleration and a preset acceleration value.

[0093] It should be noted that when the current vehicle slope is within the preset slope range, it indicates that the risk of the target vehicle falling into water is further increased. At this time, acceleration detection is performed according to the current acceleration and the preset acceleration value to determine whether the current acceleration is the preset acceleration value. In this embodiment, the preset acceleration value can be set to 0 m / s 2 .

[0094] In step D13, when the current acceleration is the preset acceleration value, the state duration is determined.

[0095] It should be noted that when the current acceleration is the preset acceleration value, the duration corresponding to the current pressure value of the target vehicle being greater than the preset pressure threshold, the current vehicle slope being within the preset slope range, and the current acceleration being the preset acceleration value is obtained. The above duration is the state duration.

[0096] In step D14, the current state of the target vehicle is determined according to the state duration.

[0097] It should be noted that when the current pressure value of the target vehicle is greater than the preset pressure threshold, the current vehicle slope is within the preset slope range, the current acceleration is the preset acceleration value, and the state duration exceeds the preset time threshold, it indicates that the current state of the target vehicle is the target water landing state. In the embodiment, the preset time threshold can be set to 2s, or other values, and the embodiment does not limit this. When any one of the four conditions is not met, that is, the current pressure value of the target vehicle is not greater than the preset pressure threshold, the current vehicle slope is not within the preset slope range, the current acceleration is not the preset acceleration value, and the state duration does not exceed the preset time threshold, it indicates that the current state of the target vehicle is not the target water landing state, and at this time the electric door controller will not drive the door to open, such as normal rain flooding, slope parking, etc. to prevent the door from opening and causing people to fall out of the cabin.

[0098] It can be understood that the embodiment can also be directly based on the current pressure value, the current vehicle slope, and the current acceleration to determine that when the current pressure value is greater than the preset pressure threshold, the current vehicle slope is within the preset slope range, and the current acceleration is the preset acceleration value, it is determined that the target vehicle is water landing; if the three conditions do not occur at the same time, it is determined that the target vehicle has not landed in water.

[0099] In the embodiment, when the current pressure value is greater than the preset pressure threshold, the slope is detected according to the current vehicle slope and the preset slope range; when the current vehicle slope is within the preset slope range, the acceleration is detected according to the current acceleration and the preset acceleration value; when the current acceleration is the preset acceleration value, the state duration is determined; and the current state of the target vehicle is determined according to the state duration. Through the above manner, the current state of the target vehicle can be accurately determined by combining the current pressure value, the current vehicle slope, and the current acceleration, and the misjudgment condition is avoided.

[0100] In a possible implementation, step D14 can further include steps E11-E12:

[0101] Step E11, when the state duration exceeds the preset time threshold, it is determined that the current state of the target vehicle is the target water landing state.

[0102] Step E12, when the state duration does not exceed the preset time threshold, it is determined that the current state of the target vehicle is not the target water landing state.

[0103] It should be noted that when the state duration of the target vehicle exceeds the preset time threshold, it indicates that the sensor misperception does not occur at this time, and it is determined that the current state of the target vehicle is the target water landing state; when the state duration of the target vehicle does not exceed the preset time threshold, it indicates that the sensor misperception occurs at this time, and it is determined that the current state of the target vehicle is not the target water landing state.

[0104] In the embodiment, when the state duration exceeds the preset time threshold, it is determined that the current state of the target vehicle is the target water landing state; when the state duration does not exceed the preset time threshold, it is determined that the current state of the target vehicle is not the target water landing state. Through the above-mentioned manner, the occurrence of the water landing event can be accurately determined.

[0105] The embodiment provides a vehicle door unlocking method, and the embodiment determines a current pressure value according to water pressure data collected by a water pressure sensor; determines a current vehicle slope according to slope data collected by a slope sensor; determines a current acceleration according to acceleration data collected by a collision acceleration sensor; and performs state judgment according to the current pressure value, the current vehicle slope and the current acceleration to determine the current state of the target vehicle. Through the above-mentioned manner, the current state of the target vehicle can be accurately determined by combining the current pressure value, the current vehicle slope and the current acceleration, and the misjudgment can be avoided.

[0106] Exemplarily, to facilitate understanding of the implementation process of the vehicle door unlocking method obtained by combining the above-mentioned embodiment with the embodiment, specifically:

[0107] The vehicle door unlocking method of the embodiment judges the water landing event in the following manner: when an emergency water landing or an emergency water immersion condition occurs, the water pressure sensor collects a water pressure value, under normal circumstances, the vehicle head is inclined, the vehicle slope sensor collects the state of the vehicle, and the acceleration sensor collects the acceleration of the vehicle. After the water landing event occurs: the water pressure sensor (design height h1, recommended value less than 800-1000mm from the ground) designed on the vehicle door plastic part detects that the pressure value is greater than ρgh1; the vehicle slope sensor collects the state of the vehicle and sends the slope information to the electric door controller POD to detect whether the vehicle slope is within a predetermined range; and the collision acceleration sensor sensing value will be 0m / s 2, the BCM receives the 3 values in parallel and judges that the falling into water event occurs after 2 seconds. After the falling into water event occurs: the BCM sends the falling into water event information to the electric vehicle door controller POD, the POD sends a signal to the electric door opening and closing function through software. The electric door controller door lock is unlocked, and the electric door mechanism is driven to open the vehicle door to a predetermined angle. The electric door driving mechanism opening force is designed to be 30N under normal working conditions, which can open the vehicle door. Under normal conditions, the opening force duty cycle is about 1 / 15, and the vehicle door unlocking time is about 500ms-800ms; under the set working condition, when the vehicle is in water, the electric door driving mechanism opening force duty cycle is adjusted to 0% after the electric door controller POD judges that it falls into water, and the opening force is increased to the extreme value of 500N, and the electric limit stopper provides an opening force of 150N, which opens the vehicle door through the force. Under this condition, the vehicle door unlocking time window is increased, and the electric driving mechanism and the limit stopper continuously provide the opening force to cope with the internal and external pressure difference.

[0108] In the above manner, the following effects can be achieved: 1. The vehicle door is automatically opened by the electric vehicle door when falling into water, avoiding the risk that the vehicle door cannot be opened due to water pressure and the like; 2. With frequent severe weather in cities, the electric vehicle door can be automatically opened under severe working conditions through software extension, reducing personnel casualties; 3. The vehicle state information is sensed through the vehicle slope sensor, avoiding the risk that the passenger falls out of the cabin when the vehicle door is opened at an abnormal slope.

[0109] It should be noted that the above examples are only used to understand the present application and do not limit the vehicle door unlocking method of the present application. More forms of simple changes based on this technical concept are within the protection scope of the present application.
