Description

Technical Field

[0001] This invention relates to the field of automation control technology, and in particular to an automatic closing method and related device for vehicle doors. Background Technology

[0002] Automation control technology is widely used in various industries due to its convenience. For example, electric doors in the automotive industry require the vehicle user to close them manually or by inputting commands. These doors are semi-automatic control doors that are manually triggered.

[0003] With the continuous improvement of automation control technology, the automotive industry has increasingly higher requirements for semi-automatic car doors. For example, the patent publication CN114439347A, published on May 6, 2022, entitled "A Logic Method for Closing / Locking the Car by Double-Clicking the Tailgate Control Button," discloses a logic method for closing / locking the car by double-clicking the tailgate control button. Its features include the following steps: First, double-clicking the tailgate control button; second, judging the double-click tailgate opening / closing signal and the vehicle locking signal; third, judging the tailgate closing condition; fourth, judging the vehicle locking condition. After judging that the tailgate closing signal and the vehicle locking signal sent by the tailgate control button to the tailgate controller are valid and the tailgate closing condition is met, the judgment is made on whether the vehicle locking condition is met: if the vehicle locking condition is not met, the vehicle locking action is not performed after the tailgate closing action; if the vehicle locking condition is met, the vehicle is locked when a preset time interval t2 is reached. This invention enables the entire vehicle to be locked without pressing the lock button on the car key after the tailgate is closed.

[0004] Existing semi-automatic car doors cannot recognize the user's intention to close the door and close it automatically, lacking intelligence and convenience features, which to some extent affects the user's experience. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to realize a method and system for automatically closing vehicle doors by recognizing the vehicle user's intention to close the door, thereby improving the intelligence and convenience of the vehicle.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: an automatic closing control method for vehicle doors, comprising the following steps:

[0007] Step 1: Obtain relevant status information for the automatic closing of the car doors.

[0008] Step 2: When the relevant status information of the automatic door closing meets the preset conditions, output the door closing command;

[0009] Step 3: Execute the door closing command;

[0010] The relevant status information for automatically closing the car door includes the door opening status, whether there is a passenger on the seat, and whether the seat belt buckle is inserted into the seat.

[0011] Each door independently executes an automatic closing control method. If the relevant status information of one of the doors and the seat on its side meets the preset conditions, then only the closing command of that door will be output.

[0012] The following conditions must be met simultaneously for the doors to close automatically after boarding:

[0013] The car door is open, there are passengers in the seats, and the seatbelt buckles are inserted into the seats.

[0014] Use the open state of the car door as the trigger program for the automatic closing control method;

[0015] If, within a set time after the automatic closing control method is activated, the seat changes from being empty to having a passenger, and the seatbelt buckle changes from being free to being inserted, the seatbelt buckle signal is used as the trigger signal to execute the door closing command.

[0016] During the automatic closing control process, a prompt sound is emitted when the seat changes from being empty to having a passenger. The function of emitting the prompt sound is optional, and the prompt sound is emitted only once in a short period of time.

[0017] The following conditions must be met simultaneously for the car doors to close automatically after the passenger exits:

[0018] The car door was open, there were no passengers in the seats, and the seatbelt buckles had come off the seats.

[0019] Use the open state of the car door as the trigger program for the automatic closing control method;

[0020] If, within a set time after the automatic closing control method is activated, the seat belt buckle changes from the inserted state to the free state and the seat changes from having a passenger to not having a passenger, then the seat no-passenger status information is used as a delayed trigger signal to execute the door closing command.

[0021] During the automatic closing control process, a prompt sound is emitted when the seat belt buckle changes from the inserted position to the free position. The function of emitting the prompt sound is optional, and the prompt sound is emitted only once in a short period of time.

[0022] The automatic door closing control system includes:

[0023] The door status detection module is used to acquire door status information, specifically door open / close status information, and transmit the acquired status information to the door control module.

[0024] The seat pressure detection module is used to obtain information on whether there is someone on the seat and transmit the collected information to the door control module.

[0025] The seat belt status detection module is used to acquire the status information of the seat belt buckle and transmit the acquired status information to the door control module;

[0026] The door control module receives status information from the door status detection module, seat pressure detection module, and seat belt status detection module. If the status information received from the three modules in sequence meets the preset conditions, the module outputs a command to close the door.

[0027] The door drive module is used to receive the door closing command from the door control module and perform the action of electrically closing the door.

[0028] The vehicle door refers to a car door, and the car includes, but is not limited to, fuel-powered vehicles, pure electric vehicles, range-extended vehicles, hybrid vehicles, and hydrogen fuel cell vehicles.

[0029] The door drive module has an anti-pinch function unit.

[0030] A storage medium, the storage medium being a computer-readable storage medium for storing software program code, the software program code being for executing an automatic closing control method for a vehicle door.

[0031] This invention determines whether an automatic door closing command has been issued by sequentially detecting the vehicle's door status, whether there are passengers sitting in the seats, and whether the seat belt buckle is inserted into the seat, thereby controlling the automatic door closing and improving the vehicle's intelligence and convenience, and enhancing the user experience to a certain extent. Attached Figure Description

[0032] The following is a brief explanation of the content represented by each figure in this specification:

[0033] Figure 1 A flowchart illustrating the automatic closing method of the car doors;

[0034] Figure 2 This is a schematic diagram of the automatic door closing device. Detailed Implementation

[0035] The following description, with reference to the accompanying drawings, details the specific implementation of the present invention, including the shape and structure of each component, the relative positions and connections between the parts, the function and working principle of each part, the manufacturing process, and the operation and use methods, to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of the present invention.

[0036] Automatic door closing control system, such as Figure 2 As shown, it includes the following modules:

[0037] The door status detection module 201 is used to detect whether the door is in an open state, and outputs a corresponding feedback signal to the door control module 204 according to the current status of the door.

[0038] The seat pressure detection module 202 is used to detect whether the pressure value on the seat is not less than a set threshold. If it is, it means that no one is sitting on the seat; otherwise, it means that someone is sitting on the seat. Based on the current seat pressure data, the module outputs a corresponding feedback signal to the door control module 204.

[0039] The seat belt status detection module 203 is used to detect whether the seat belt buckle is inserted into the buckle holder. If yes, it means that the seat belt buckle is inserted into the buckle holder. If no, it means that the seat belt buckle is free. The module outputs a corresponding feedback signal to the door control module 204 according to the current seat belt buckle status.

[0040] The door control module 204 is used to determine whether to receive feedback data from the door status detection module 201, the seat pressure detection module 202 and the seat belt status detection module 203 in sequence, and output a door closing command according to the preset control logic.

[0041] The door drive module 205 is used to receive output commands from the door control module 204. If a door closing command is received, the door drive module 205 drives the door to perform a closing action. Because it is a non-manually operated system, the door drive module has an anti-pinch function unit. The control logic of the system is stored in a computer-readable storage medium. The computer-readable storage medium is used to store the program code of the automatic door closing method. The storage medium is generally located in the control unit within the automatic door closing control system. The automatic door closing control system can be applied to any type of vehicle, such as fuel vehicles, pure electric vehicles, range-extended vehicles, hybrid vehicles, and hydrogen fuel cell vehicles.

[0042] The automatic door closing control system includes the boarding and alighting phases;

[0043] Control methods during the boarding phase:

[0044] Step 101: The door status detection module detects whether the door is open; if the door status detection module detects that the door is open, it provides positive feedback to the door control module.

[0045] Step 102: The seat pressure detection module detects whether there is a passenger sitting on the seat; if the seat pressure detection module detects that the pressure on the seat is not less than the set threshold, it determines that there is a passenger sitting on the seat and gives positive feedback to the door control module.

[0046] Step 103: The seat belt status detection module detects whether the seat belt buckle is inserted into the buckle holder; if the seat belt status detection module detects that the seat belt buckle has been inserted into the buckle holder, it provides positive feedback to the door control module.

[0047] Step 104: The door control module outputs a door closing command based on the data fed back from the three detection modules. The door control module outputs a door closing command if it receives positive feedback data from the door status detection module, seat pressure detection module, and seat belt status detection module in sequence.

[0048] Step 105: The door drive module receives the instruction from the door control module to close the door; the door drive module will only control the door to close when it receives the instruction from the door control module to close the door.

[0049] To improve system reliability, prevent accidental door opening, and reduce the workload of the control system, the automatic door closing function is normally disabled. The automatic closing control method is triggered when the door is open. After the door is opened, the automatic door closing function is activated. If the door closing function is not triggered within a set time, the automatic door closing function will be disabled again, usually after a delay of about 1 minute. This is to prevent the function from being misoperated in special circumstances such as door sensor failure or car repair, which could cause inconvenience to passengers or staff.

[0050] The automatic door closing function is an independent control of each door and its corresponding seat. For example, when the driver's side door is opened, the information of the driver's seat and seat belt is directly obtained. If other doors are opened, they are also controlled independently. The automatic closing functions of seats and doors in the same position are independent of each other and do not affect each other.

[0051] When the automatic door closing function is activated, if the seat changes from being empty to having a passenger and the seatbelt buckle changes from being free to being inserted, the seatbelt buckle signal serves as the trigger signal for executing the door closing command. As a trigger signal, this allows the driver and passengers to immediately feel the door closing when they buckle their seatbelts, linking buckling the seatbelt with door closing and providing a strong sense of linkage. This not only enhances the driver and passengers' awareness of actively buckling their seatbelts but also improves door closing efficiency and user experience.

[0052] During the automatic closing control process, a prompt sound is emitted when the seat changes from being empty to having a passenger, such as an audio prompt saying "Fasten your seatbelt and the door will close automatically." This helps people know how to activate the automatic door closing function. For non-commercial vehicles, this function can be turned off in the vehicle's infotainment system. The prompt sound function is optional and can be selected in a user-friendly way. Furthermore, the prompt sound will only be emitted once in a short period of time, such as not emitting another prompt sound within 20 seconds of the initial sound, to avoid triggering the prompt sound continuously when multiple people board the vehicle one after another, which could cause discomfort to the user.

[0053] Disembarkation phase control methods:

[0054] Step 101: The door status detection module detects whether the door is open; if the door status detection module detects that the door is open, it provides positive feedback to the door control module; if the door status detection module detects that the door is closed, it provides negative feedback to the door control module.

[0055] Step 102: The seat pressure detection module detects whether there is a passenger sitting on the seat; if the seat pressure detection module detects that the pressure on the seat is less than the set threshold, it determines that there is no passenger on the seat and sends a negative feedback to the door control module.

[0056] Step 103: The seat belt status detection module detects whether the seat belt buckle is inserted into the buckle holder; if the seat belt status detection module detects that the seat belt buckle is not inserted into the buckle holder, it sends negative feedback to the door control module.

[0057] Step 104: The door control module outputs a door closing command based on the data fed back from the three detection modules. The door control module outputs a door closing command if it receives positive feedback data from the door status detection module, negative feedback data from the seat pressure detection module, and negative feedback data from the seat belt status detection module in sequence.

[0058] Step 105: The door drive module receives the instruction from the door control module to close the door; the door drive module will only control the door to close when it receives the instruction from the door control module to close the door.

[0059] To reduce system reliability, prevent accidental door opening, and reduce the workload of the control system, the automatic door closing function is normally disabled. The system uses the open door state as the trigger for automatic closing. Once the door is opened, the automatic door closing function is activated. If the door does not close within a set time, it is deactivated again, typically after a delay of about one minute. If the occupants have unbuckled their seatbelts and are still not out of the vehicle, this indicates a special situation where automatic closing is no longer necessary. This prevents accidental operation during vehicle repairs, driver rest, or other special circumstances. If the occupants are still not out of the vehicle after the delay time, they will need to manually close the door. If the door closes again, the automatic closing function restarts and will be triggered again the next time the door is opened.

[0060] The automatic door closing function is an independent control of each door and its corresponding seat. For example, when the driver's side door is opened, the information of the driver's seat and seat belt is directly obtained. If other doors are opened, they are also controlled independently. The automatic closing functions of seats and doors in the same position are independent of each other and do not affect each other.

[0061] When the automatic closing function of a certain door is activated, if the seat belt buckle of the seat changes from the inserted state to the free state, and the seat changes from having a passenger to not having a passenger, then the information of the seat not having a passenger is used as a delayed trigger signal to execute the door closing command. The delay is generally about 10 seconds and can be set automatically, so as to give people enough time to get out of the car and the route to leave the closed door.

[0062] During the automatic closing control process, a prompt sound is emitted when the seat belt buckle changes from the inserted position to the free position, such as "The door will automatically close 10 seconds after you get out of the vehicle." This helps people know how to activate the automatic door closing function. For non-commercial vehicles, this function can be turned off in the vehicle's infotainment system. The prompt sound function is optional and can be selected in a user-friendly way. The prompt sound will only be emitted once in a short period of time, such as not emitting another prompt sound within 20 seconds of the initial sound, to avoid triggering the prompt sound continuously when multiple people get out of the vehicle one after another, which could cause discomfort to the users.

[0063] In the exit phase control method, if there is a passenger in the middle position of the rear seat, a special control logic is activated. When the rear door is opened, the exit door's built-in closing control function is activated. If there is a passenger in the middle rear seat at this time, the special control logic is activated.

[0064] Special control logic: If the left rear door is opened, the automatic closing function is activated. Information on whether there is a passenger in the middle position is obtained. If there is, when the seat belt buckle on the left seat changes from the inserted state to the free state and the seat changes from having a passenger to not having a passenger, the information on the seat not having a passenger is used as a delayed trigger signal to execute the door closing command. During the delay time, the pressure signal of the left rear seat is collected.

[0065] If the left seat generates a pressure signal and fluctuates, eventually becoming 0, the delay time will be extended (approximately 3-8 seconds), and the door will automatically close after the extended delay time is reached.

[0066] If no pressure signal is generated, or if the pressure signal fluctuates after being generated and eventually becomes a relatively stable value, the door will automatically close after the initial delay time is reached.

[0067] Similarly, if the rear right door is opened, the automatic closing function is activated to obtain information on whether there is a passenger in the middle position. If there is, when the seat belt buckle on the right seat changes from the inserted state to the free state and the seat changes from having a passenger to not having a passenger, the information on the seat not having a passenger is used as a delayed trigger signal to execute the door closing command. During the delay time, the pressure signal of the rear right seat is collected.

[0068] If the right-side seat generates a pressure signal and fluctuates, eventually becoming 0, the delay time will be extended (approximately 3-8 seconds), and the door will automatically close after the extended delay time is reached.

[0069] If no pressure signal is generated, or if the pressure signal is generated but fluctuates and eventually becomes a relatively stable value, the door will automatically close after the initial delay time is reached.

[0070] If both rear doors are open, the automatic closing function of the two rear doors is activated. Information on whether there is a passenger in the middle position is obtained. If there is, the information on whether the seat belt buckle on the seat on the middle side changes from the inserted state to the free state, and whether the seat changes from having a passenger to not having a passenger is obtained. The information on the seat not having a passenger is used as a delayed trigger signal to execute the door closing command. During the delay time, the pressure signals of the rear seats on both sides are collected.

[0071] If a pressure signal is generated on one side of the seat and fluctuates, eventually becoming zero, the delay time will be extended (approximately 3-8 seconds), and the door on that side will be automatically closed after the extended delay time is reached.

[0072] If one of the seats does not generate a pressure signal, or if the pressure signal fluctuates after it is generated and eventually becomes a relatively stable value, the door on that side will automatically close after the initial delay time is reached.

[0073] The aforementioned system and control method enable the car doors to close intelligently and automatically, reducing the need for getting in and out of the vehicle. In particular, if you have a lot of things in your hands after getting out, the doors can close automatically, enhancing the vehicle's premium feel and intelligence. This solution is intelligent and convenient to operate, which can improve the user experience to a certain extent.

[0074] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
