[0030] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0034] like Figure 1 As shown, the door control system provided in this application includes multiple emergency control modules 100 and a door execution module 200 installed in each door of the vehicle. The emergency control modules 100 are communicatively connected to the door execution modules 200 respectively.
[0035] The emergency control module 100 is used to detect vehicle collision events and send a first door opening signal to the door execution module 200 based on the vehicle collision event.
[0036] The door execution module 200 is used to receive the first door opening signal and execute the door opening action according to the first door opening signal.
[0037] Based on the aforementioned door control system, the emergency control module 100 is communicatively connected to each door execution module 200. After detecting a vehicle collision, it automatically sends a door opening signal to the door execution module 200, ensuring that each door execution module 200 can receive the door opening signal.
[0038] Furthermore, by placing multiple emergency control modules 100 in different locations within the vehicle, the probability of all emergency control modules 100 being damaged simultaneously in a vehicle collision is reduced, increasing the probability of them being able to send a normal door opening signal. This, in turn, increases the likelihood of the door opening, facilitating the escape of occupants or rescue by personnel. Therefore, even if the door control module corresponding to the door execution module 200 is damaged, preventing the user from manually opening the door, the door execution module 200 can still receive at least one first door opening signal from the emergency control module 100, thus automatically executing the door opening action.
[0039] The emergency control module 100 and the door execution module 200 can be connected by wired communication.
[0040] In an embodiment, the emergency control module 100 is connected to each door execution module 200 by a wired signal line, respectively. That is, the emergency control module 100 can send a door opening signal to each door execution module 200 by a wired signal line, respectively.
[0041] Considering the wiring cost and the wired signal line being easily cut off by accident, the emergency control module 100 and the door execution module 200 can also be connected by wireless communication.
[0042] In another embodiment, the emergency control module 100 is provided with a first wireless communication unit, and the emergency control module 100 is configured to send a first door opening signal to the door execution module 200 through the first wireless communication unit according to a vehicle collision event. The door execution module 200 is provided with a second wireless communication unit, and the door execution module 200 is configured to receive the first door opening signal through the second wireless communication unit.
[0043] In this embodiment, through the first wireless communication unit and the second wireless communication unit, a wireless signal line can be established between the emergency control module 100 and each door execution module 200, respectively, to ensure that the door opening signal can be normally sent and received.
[0044] The first wireless communication unit and the second wireless communication unit communicate based on Zigbee (a wireless communication protocol) protocol. Zigbee is a two-way wireless communication technology, which has the advantages of low power consumption, low cost and easy networking.
[0045] It can be understood that the emergency control module 100 can be arranged at the front, rear and cabin of the vehicle. However, compared with the front and rear of the vehicle, the top, bottom and side of the vehicle are less likely to be damaged, and the emergency control module 100 can be arranged at these positions to avoid the emergency control module 100 being damaged at the same time as much as possible.
[0046] In an embodiment, the emergency control module 100 is arranged at at least two of the top, bottom and side of the vehicle.
[0047] For example, the door control system includes four emergency control modules 100, which are arranged on the top and bottom of the vehicle corresponding to the front seats and the rear seats, and on the two sides of the vehicle corresponding to the front seats and the rear seats.
[0048] It can be understood that the area between the front seats and the rear seats of the vehicle is always the area least affected by the collision when the vehicle collides from any side. Therefore, the emergency control module 100 is arranged in the area corresponding to the front seats and the rear seats of the vehicle, which can reduce the possibility of damage to the emergency control module 100.
[0049] The emergency control module 100 can determine whether a vehicle collision event occurs according to the acceleration of the vehicle and the smoke concentration in the vehicle.
[0050] In one embodiment, each emergency control module 100 is provided with a corresponding acceleration sensing module, and the acceleration sensing module is connected to the corresponding emergency control module 100.
[0051] The emergency control module 100 is used to obtain the real-time acceleration of the vehicle through the acceleration sensing module, and send a first vehicle door opening signal to the vehicle door execution module 200 when the absolute value of the real-time acceleration is greater than a preset acceleration.
[0052] It should be noted that when the vehicle collides, the vehicle speed will instantaneously slow down to 0, that is, the real-time acceleration is actually a negative number, but the absolute value of the real-time acceleration is much greater than the acceleration when the vehicle is normally accelerated. Therefore, when the emergency control module 100 detects that the absolute value of the real-time acceleration is greater than the preset acceleration, it can be determined that a vehicle collision event has occurred, and then automatically sends a first vehicle door opening signal to the vehicle door execution module 200.
[0053] In another embodiment, each emergency control module 100 is provided with a corresponding smoke sensing module, and the smoke sensing module is connected to the corresponding emergency control module 100.
[0054] The emergency control module 100 is used to obtain the internal smoke concentration of the vehicle through the smoke sensing module, and send a first vehicle door opening signal to the vehicle door execution module 200 when the internal smoke concentration is greater than a preset concentration.
[0055] It should be noted that the collision of the vehicle may cause a fire, thereby generating smoke. At this time, the smoke concentration in the vehicle will rapidly increase and be much greater than the smoke concentration generated by smoking at ordinary times. Therefore, when the emergency control module 100 detects that the smoke concentration in the vehicle is greater than the preset concentration, it can be determined that a vehicle collision event has occurred, and then automatically sends a first vehicle door opening signal to the vehicle door execution module 200.
[0056] Each emergency control module 100 can also be provided with a corresponding acceleration sensing module and a smoke sensing module. The emergency control module 100 can determine that a vehicle collision event has occurred according to one of the acceleration and the smoke concentration, and then automatically sends a first vehicle door opening signal to the vehicle door execution module 200.
[0057] For example, the acceleration sensing module can employ an acceleration sensor to convert the acceleration signal into an electric signal. The smoke sensing module can employ a smoke sensor to convert the smoke concentration signal into an electric signal. The emergency control module 100 and the door control module can employ various units capable of generating adjustable signals, such as various single-chip microcomputers, microcontrollers, DSPs (Digital Signal Processors), FPGAs (Field-Programmable Gate Arrays), host computers, or CPUs (Central Processing Units).
[0058] In this embodiment, the emergency control module 100 can employ a single-chip microcomputer, and various control functions can be realized by programming the single-chip microcomputer. For example, the electric signals converted from the collected acceleration and smoke concentration can be used to detect whether a vehicle collision event has occurred. When a vehicle collision event is detected, the emergency control module 100 can automatically send a first door opening signal to the door actuator module 200.
[0059] However, considering the possibility of false positives in determining whether a vehicle collision event has occurred based on acceleration or smoke concentration, the first door opening signal sent by the emergency control module 100 can be shielded when the door actuator module 200 and the corresponding vehicle controller can normally communicate.
[0060] On a vehicle, each door actuator module 200 has a corresponding door control module, and the door actuator module 200 is communicatively connected to the corresponding door control module on the vehicle. The door control module is configured to send a second door opening signal to the corresponding door actuator module 200 based on user operation.
[0061] In one embodiment, the door actuator module 200 is further configured to shield the first door opening signal when the communication connection between the door actuator module 200 and the corresponding door control module is normal, receive the second door opening signal sent by the door control module, and perform a door opening action based on the second door opening signal.
[0062] In this embodiment, the door actuator module 200 can theoretically receive both the first door opening signal from the emergency control module 100 and the second door opening signal from the corresponding door control module. However, when the communication connection between the door actuator module 200 and the corresponding door control module is normal, the first door opening signal can be shielded to prevent misoperation.
[0063] In addition, the door actuator module 200 is usually powered by a vehicle power supply module. However, considering the possibility of accidental disconnection of the power supply line, a corresponding backup power supply can be provided for each door actuator module 200.
[0064] In one embodiment, each door execution module 200 is connected with a vehicle power supply module, which is configured to supply power to the door execution module based on a power supply line; and each door execution module is further provided with a corresponding first power supply module, which is configured to supply power to the corresponding door execution module 200 when the corresponding power supply line is disconnected.
[0065] Similarly, the emergency control module 100 can also be powered by a vehicle power supply module. However, considering that the power supply line is easily disconnected by accident, and the emergency control module 100 needs to be replaced conveniently after being damaged, an independent power supply module can be provided for each emergency control module 100.
[0066] In one embodiment, each emergency control module 100 is provided with a corresponding second power supply module, which is connected with the corresponding emergency control module 100 and configured to supply power to the corresponding emergency control module 100.
[0067] The door control system can be used as an execution carrier of a line structure, for example, each module / unit is configured as a component of a product, and the connection between each module / unit is configured as a certain connection relationship between components of the product. The signal can be collected, processed and output through the components of the product, so as to achieve the purpose of automatically opening the door after detecting the vehicle collision event.
[0068] In the following, the door control system will be described through a specific example.
[0069] The door control system includes a plurality of emergency control modules 100 arranged at different positions of the vehicle.
[0070] As shown in Figure 2 The emergency control module 100 is connected with the corresponding acceleration sensing module 102, smoke sensing module 103 and second power supply module 104 respectively, and is integrated in an entity emergency control device 300, which is convenient for installation and replacement.
[0071] That is, the door control system includes a plurality of emergency control devices 300 arranged at different positions of the vehicle. Each emergency control device 300 includes an emergency control module 100, an acceleration sensing module 102, a smoke sensing module 103 and a second power supply module 104. The emergency control module 100 is electrically connected with the acceleration sensing module 102, the smoke sensing module 103 and the second power supply module 104 respectively.
[0072] The second power supply module 104 is configured to supply power to the corresponding emergency control module 100. The acceleration sensing module 102 and the smoke sensing module 103 are respectively configured to collect the real-time acceleration of the vehicle and the smoke concentration in the vehicle, and feed back to the emergency control module 100.
[0073] Each emergency control module 100 is provided with a first wireless communication unit 101. The emergency control module 100 can determine whether a vehicle collision event occurs according to the real-time acceleration fed back by the acceleration sensing module 102 and the smoke concentration in the vehicle fed back by the smoke sensing module 103. If a vehicle collision event is detected, the emergency control module 100 will automatically send a first door opening signal to the door execution module 200 through the first wireless communication unit 101.
[0074] As shown in Figure 3 The door execution module 200 provided on each door of the vehicle is in communication connection with the corresponding door control module 400.
[0075] Under normal circumstances, the door control module 400 and the door execution module 200 are both connected to the vehicle power supply module 500 and powered by the vehicle power supply module 500.
[0076] Each door execution module 200 is also connected to its corresponding first power supply module 202. When the power supply line between the door execution module 200 and the vehicle power supply module 500 is disconnected, the door execution module 200 is powered by the first power supply module 202.
[0077] Each door execution module 200 is provided with a second wireless communication unit 201 for receiving the first door opening signal sent by the emergency control module 100 and executing the door opening action according to the first door opening signal, so as to automatically open the door after a vehicle collision event occurs.
[0078] The door control module 400 is in communication connection with the corresponding door execution module 200. The door control module 400 can send a second door opening signal to the door execution module 200 based on the wired signal line according to user operation.
[0079] When the communication connection between the door control module 400 and the door execution module 200 is normal, i.e. the wired communication line is not disconnected, the door execution module 200 can receive both the first door opening signal and the second door opening signal at the same time, but in order to avoid false positives and ensure the safety of the people in the vehicle, the first door opening signal will be shielded. That is, when the communication connection between the door control module 400 and the door execution module 200 is normal, if the first door opening signal is received but the second door opening signal is not received, the door opening action will not be executed.
[0080] When the communication connection between the door control module 400 and the door execution module 200 is disconnected, the door execution module 200 can only receive the first door opening signal sent by multiple emergency control modules 100, and then automatically open the door.
[0081] In addition, if the vehicle collision event is detected and the door is automatically opened immediately, the occupant in the vehicle can be thrown out during the collision of the vehicle, so a certain delay time can be set. That is, the emergency control module 100 can delay a certain period of time after detecting the vehicle collision event before sending the first door opening signal.
[0082] The technical features of the above embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.
[0083] The above embodiments only express several implementation manners of the present application, and the description is specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
