[0025] The following will describe the implementation methods of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, not for limiting the scope of protection of the present application.

[0026] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0027] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present application difficult to understand.

[0028] See also Figure 1 , Figure 1 is a schematic diagram of the structure of a vehicle protection system shown in an exemplary embodiment of the present application. Figure 1 It can be seen that the vehicle protection system may include:

[0029] A water falling data acquisition module 110 , a control module 120 , a feedback module 130 , and a vehicle door electric opening module 140 .

[0030] The water-falling data acquisition module 110 is connected to the control module 120 , and the water-falling data acquisition module 110 is used to acquire the water-falling data of the vehicle and send the water-falling data to the control module 120 .

[0031] The feedback module 130 is connected to the control module 120, and is used to receive the prompt information sent by the control module 120, generate feedback information after receiving the user's feedback operation, and send the feedback information to the control module 120, wherein the feedback operation is the user's operation on the feedback module according to the prompt information, and the prompt information is generated when the control module determines that the vehicle falls into water based on the falling water data.

[0032] It should be noted that, after receiving the water-falling data, the control module 120 can determine whether the vehicle has fallen into water. After determining that the vehicle has fallen into water, it can generate prompt information and send the prompt information to the feedback module 130.

[0033] The electric door opening module 140 of the automobile is connected to the control module 120, and the electric door opening module 140 of the automobile is used to receive the door opening control information sent by the control module 120. The door opening control information is generated after the control module 120 receives the feedback information sent by the feedback module 130, and the door opening control information is used to open the electric suction door lock of the electric door opening module 140 of the automobile, and drive the door opening actuator in the electric door opening module 140 of the automobile to open the door. The electric door opening module of the automobile can be an electric door, and the electric opening of the door is realized by a combination of door opening actuators, electric suction door locks, ECU and other parts installed on the door of the automobile. The electric door opening module of the automobile can receive the door opening control information sent by the control module 120, first open the electric suction door lock, and then control the door opening actuator to work, and open the side door and / or the back door of the automobile.

[0034] It should be noted that, at 25°C, the maximum motor speed No of the drive motor in the door opening actuator is 6000r / min, and the maximum torque Ts max =94.1mN·m. The drive motor in the door opening actuator directly drives the car door, without turbines, gears or other transmission mechanisms in the middle. The motor speed No can be set to 3r / min by reducing it by 2000 times, and the torque is increased by 200 times, with torque Ts = 188200mN·m = 188.2N·m. Assuming that the force exerted by water on the car door is 150kg, if a weight of m = 150kg needs to be pushed open, the required force is F = mg = 150x9.8 = 1470N, and the distance L from the drive motor to the door sheet metal is 0.1m, then the required torque M = FL = 1470x0.1 = 147N·m. The torque acts vertically on the car door. In its ideal state, torque Ts> torque M. It can be seen that the lower the speed of the drive motor of the door opening actuator (meeting the door opening requirement), the greater the torque required to push the door open.

[0035] The control module 120 is used to receive the water-falling data sent by the water-falling data acquisition module, and determine whether the vehicle falls into water based on the water-falling data. If the vehicle falls into water, a prompt message is sent to the feedback module. After receiving the feedback information sent by the feedback module, the door opening control information is sent to the car door electric opening module.

[0036] In a possible implementation, the control module may be a zonal control unit (ZCU), which can centrally process data of small controllers and actuators in the left / right zones of the vehicle.

[0037] See also Figure 2 , which is a structural diagram of a vehicle protection system according to another exemplary embodiment of the present application. The water-falling data acquisition module may include an optical liquid level sensor 111 and an inertial measurement unit 112 , and both the optical liquid level sensor 111 and the inertial measurement unit 112 are connected to a control module 120 .

[0038] The photoelectric liquid level sensor contains a near-infrared light-emitting diode and a photosensitive receiver. The light emitted by the near-infrared light-emitting diode is directed into the lens on the top of the photoelectric liquid level sensor. When the vehicle falls into the water, the liquid submerges the lens of the photoelectric liquid level sensor, and the light is refracted into the liquid, so that the photosensitive receiver can only receive a small amount of light or no light. The photoelectric liquid level sensor senses this change in the working condition, detects this change in the circuit inside the photoelectric liquid level sensor, converts it into a high-level signal, and reports it to the zone controller.

[0039] An inertial measurement unit (IMU) is a device that measures the three-axis attitude angle (or angular rate) and acceleration of an object. Generally, an IMU contains three single-axis accelerometers and three single-axis gyroscopes. The accelerometers detect the acceleration signals of the object in the three independent axes of the carrier coordinate system, while the gyroscopes detect the angular velocity signals of the carrier relative to the navigation coordinate system, measure the angular velocity and acceleration of the object in three-dimensional space, and use this to calculate the attitude of the object. When the vehicle is driving, the IMU detects the acceleration and angular velocity information of the vehicle's X-axis (pitch), Y-axis (roll), and Z-axis (yaw) in real time, and reports it to the control module via CAN signals.

[0040] The inertial measurement unit can output the CAN signal of the vehicle body posture information (that is, the water falling data) to the regional controller in real time.

[0041] In a possible implementation, the feedback module 130 may include a cockpit domain controller 131 and a central control screen 132, the central control screen 130 is connected to the cockpit domain controller 131, and the control module 120 is connected to the cockpit domain controller 131. The cockpit domain controller 131 may receive the prompt information sent by the control module 120, and display the prompt information through the central control screen, and may obtain the user's feedback operation through the central control screen, and generate feedback information, and the cockpit domain controller 131 may send the feedback information to the control module 120.

[0042] Exemplarily, the prompt message may be "The vehicle fell into water, please confirm whether to open the door". The central control screen may display "The vehicle fell into water, please confirm whether to open the door" and display two options "Yes" and "No". If the user clicks "Yes", the central control screen obtains the user's feedback operation, and the cockpit domain controller generates feedback information "The user needs to open the door". The cockpit domain controller may send the feedback information to the control module.

[0043] In a possible implementation, the feedback module 130 may include a door handle detection unit 133, which is connected to the control module 120. After the control module 120 determines that the vehicle falls into water, it can send a prompt message to the door handle detection unit 133. After the door handle detection unit 133 receives the prompt message, it can control the alarm component ( Figure 2 The door handle detection unit 133 generates feedback information after obtaining the user's feedback operation and sends the feedback information to the control module 120.

[0044] Exemplarily, the prompt message may be "The vehicle fell into water, confirm whether to open the door". After receiving the prompt message, the door handle detection unit sounds an alarm. At the same time, the door handle detection unit detects the user's door opening time and the number of times the door is opened. If the number of times the user opens the door within a preset time period is greater than a preset number, the door handle detection unit receives the user's feedback operation, and generates feedback information "The user needs to open the door" based on the feedback operation. The door handle detection unit can send the feedback information to the control module.

[0045] In a possible implementation, the feedback module 130 may include a voice unit 134, and the voice unit 134 is connected to the control module 120. After the control module 120 determines that the vehicle falls into the water, it can send a prompt message to the voice unit 134, and the voice unit 134 can broadcast the prompt message after receiving the prompt message. After obtaining the feedback operation of the user feedback, the voice unit 134 can generate feedback information according to the feedback operation and send the feedback information to the control module 120.

[0046] Exemplarily, the prompt message may be “The vehicle fell into water, confirm whether to open the door”. After receiving the prompt message, the voice unit may voice broadcast “The vehicle fell into water, confirm whether to open the door”. If the user voice feedback is “Open the door”, the voice unit obtains the user's feedback operation, and may generate feedback information “The user needs to open the door” based on the feedback operation. The voice unit may send the feedback information to the control module 120.

[0047] It should be noted that the feedback module 130 may include only the cockpit domain controller 131 and the central control screen 132, the feedback module 130 may include only the door handle detection unit 133, the feedback module 130 may include only the voice unit 134, and the feedback module 130 may include any combination of the above devices.

[0048] In a possible implementation, the vehicle protection system may further include a seat belt pop-up module 150. The seat belt pop-up module 150 may be connected to the control module 120. After the control module 120 determines that the vehicle falls into water and receives the feedback information sent by the feedback module 130, the control module 120 may send the seat belt pop-up information to the seat belt pop-up module 150 while sending the door opening control information to the vehicle door electric opening module 140. After receiving the seat belt pop-up information, the seat belt pop-up module 150 may open the seat belt buckle.

[0049] See also Figure 3 , which is a schematic diagram of the installation position of the water falling data acquisition module and the inertial measurement unit shown in an exemplary embodiment of the present application. The photoelectric liquid level sensor 111 can be installed on the A-pillar and C-pillar of the car. The photoelectric liquid level sensor 111 can also be installed on the main driver's side and the co-driver's side.

[0050] In a possible implementation, the inertial measurement unit 112 may be installed on a vehicle chassis.

[0051] In a possible implementation, the vehicle protection system further includes a waterproof battery, which is used to supply power to the vehicle to ensure that the vehicle protection system can operate stably after the vehicle falls into water.

[0052] Exemplarily, the photoelectric liquid level sensor can be installed on the A-pillar and C-pillar of the car, and two photoelectric liquid level sensors are installed on the main driver's side and the co-driver's side respectively; the IMU is installed on the chassis of the car to calibrate the posture information of the whole vehicle (including the calibration of acceleration and angular velocity of the three-axis direction X-axis (pitch), Y-axis (roll), and Z-axis (yaw)), and output the body posture information in real time. The first judgment condition: IMU detects the acceleration and angular velocity information of the vehicle's X-axis (pitch), Y-axis (roll), and Z-axis (yaw) in real time, and reports it to the regional controller with a CAN signal; the second judgment condition: the photoelectric liquid level sensor reports the detection data to the regional controller in real time (the photoelectric liquid level sensor outputs a hard-line signal, a high level indicates water, and a low level indicates normal conditions). The regional controller receives the acceleration and angular velocity of the vehicle, determines whether the X-axis (pitch), Y-axis (roll), and Z-axis (yaw) exceed the normal calibration range (first judgment condition), and the regional controller PIN angle detection level signal (second judgment condition); when the first judgment condition and the second judgment condition both reflect that the vehicle has fallen into the water, the regional controller generates a prompt message. When the feedback module includes a cockpit domain controller and a central control screen, the regional controller can report the prompt message to the cockpit domain controller through the vehicle Ethernet. When the cockpit domain controller obtains the prompt message, it triggers the "water door open" pop-up box to be displayed on the central control screen. The user can click on the central control screen and perform other operations. If the user clicks to confirm that the "water door open" function is started, the cockpit domain controller reports the feedback information to the regional controller through the vehicle Ethernet. The domain controller generates door opening control information based on the feedback information and sends the door opening control information to the electric opening module of the car door. After the electric door opening module of the car receives the door opening control information, it opens the electric suction door lock of the electric door opening module of the car, and drives the door opening actuator in the electric door opening module of the car to open the door. After the electric door opening module of the car receives the door opening control information, the regional controller detects that the vehicle Ethernet signal of the electric door opening module of the car changes from Inactive to Active, and can send an enhanced service signal to the drive motor of the door opening actuator to adjust the drive power of the drive motor to the highest gear to open the door. When the door is fully opened, the regional controller detects that the release signal of the electric suction door lock changes from high level (closed) to low level (opened), and reversely drives the release motor of the electric suction door lock to reset. Finally, the information that the door has been opened can be fed back to the central control screen through the cockpit domain controller.

[0053] Among them, the IMU mainly uses the pitch angle of the X-axis as the standard. Within the specified cycle period (for example: 500ms), it detects whether the pitch angle exceeds the threshold of ±30°. The pitch angle calculation formula is as follows: Angle = arctan (ΔZ / ΔX). The logic is processed and calculated by the regional controller to perform threshold judgment. If the pitch angle exceeds the threshold, it is determined that the vehicle has fallen into the water.

[0054] It should be noted that when the feedback module includes a cockpit domain controller and a central control screen, the vehicle protection system provided by the embodiment of the present application can adopt the following communication methods: ① Photoelectric liquid level sensor: output hard-line signal, high level means water is present, low level means normal situation; ② Regional controller: one is to input and output hard-line signals, such as high and low levels, resistance, etc., through the PIN angle (pin) of the interface end of the domain controller, and the other is to input and output vehicle bus signals for other controllers or actuators; ③ Cockpit domain controller: receive the vehicle Ethernet signal input by the regional controller, output the corresponding function request to the central control screen for display, receive the feedback information fed back by the central control screen, and send the feedback information to the regional controller; ④ Central control screen: as an actuator, receive the prompt information sent by the cockpit domain controller for correct display, receive the user's feedback operation, and generate feedback information; ⑤ IMU: real-time output of vehicle body posture information CAN signal to the regional controller; ⑥ Automobile door electric opening module: one is to receive the vehicle bus input and output control of the regional controller, and the other is to drive the drive motor of the door opening actuator through hard-line signals, high and low levels.

[0055] In summary, the embodiment of the present application provides a vehicle protection system, which includes a water-falling data acquisition module, a control module, a feedback module, and an electric door opening module for automobiles; the water-falling data acquisition module is connected to the control module, the feedback module is connected to the control module, and the electric door opening module for automobiles is connected to the control module. After the control module determines that the vehicle has fallen into water through the data transmitted by the water-falling data acquisition module, the feedback module receives the user's feedback operation to open the electric suction door lock of the electric door opening module for automobiles, and drives the door opening actuator in the electric door opening module for automobiles to open the door, so that it can detect whether the vehicle has fallen into water, and automatically open the door according to the feedback operation of the occupants, so as to help the occupants escape.
