Abstract
Description
Technical Field
[0001] This invention belongs to the field of automotive technology. Specifically, this invention relates to a door control method, system, and vehicle. Background Technology
[0002] For vehicles with three rows of seats, doors are only located at the positions corresponding to the front and rear rows of seats. Passengers in the third row need to adjust the second row of seats before entering or exiting, creating a narrow passage that makes it difficult to escape quickly in an emergency.
[0003] In the existing technology, although a solution has been proposed to set a third-row safety door on the vehicle body, the passage for third-row passengers is widened by setting a safety door at the vehicle body position corresponding to the third-row seats. However, there is a lack of linkage control between the safety door and the surrounding moving parts.
[0004] When the safety door is operated simultaneously with other moving parts (such as the second-row side door, charging port cover, fuel filler cap, and other surrounding moving parts), there is a risk of mutual interference or even collision, which restricts the further improvement of the safety and comfort of third-row passengers getting on and off the vehicle. Summary of the Invention

[0091] To make the technical problems, technical solutions, and advantages of this invention clearer, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0092] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. The vehicle body longitudinal direction (X-direction) refers to the length direction of the vehicle body, that is, the direction defined by the forward and reverse directions when the vehicle is normally driving; the vehicle body width direction (Y-direction) refers to the direction perpendicular to the vehicle body longitudinal direction and the vehicle body height direction (Z-direction).
[0093] Furthermore, in the following embodiments, the terms "first," "second," and "third" do not represent an absolute distinction in structure and / or function, nor do they represent a sequential execution order; they are merely for the convenience of description.
[0094] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0095] In a first aspect, embodiments of the present invention provide a door control method, applied to a vehicle, such as... Figure 15 and Figure 16 As shown, the vehicle includes a body 101 and a first vehicle side door, a second vehicle side door 102, a third-row side door 103, and a sealing cover disposed on the body 101. The third-row side door 103 is located between the second vehicle side door 102 and the sealing cover. The sealing cover, the first vehicle side door, the second vehicle side door 102, and the third-row side door 103 are rotatably connected to the body 101. The sealing cover, the second vehicle side door 102, and the third-row side door 103 can rotate outward toward the body 101 to complete the opening action.
[0096] The first vehicle side door is located in front of the second vehicle side door 102, the second vehicle side door 102 is located in front of the third row side door 103, and the sealing cover is located behind the third row side door 103. The sealing cover includes a fuel filler cap or a charging cap. The fuel filler cap is used to control the opening and closing of the fuel filler cap provided on the vehicle body 101, and the charging cap is used to control the opening and closing of the charging port provided on the vehicle body 101.
[0097] The vehicle also includes a first row of seats, a second row of seats 104 and a third row of seats 105. The first row of seats, the second row of seats 104 and the third row of seats 105 are arranged sequentially along the X direction inside the vehicle body 101. The second row of seats 104 is movably installed inside the vehicle body 101. The second row of seats 104 is mounted on the floor inside the vehicle body 101 via a sliding rail assembly. It can move in the front-to-back direction of the vehicle body and also move towards the inside of the vehicle body in the width direction. The backrest of the second row of seats 104 can also be tilted forward relative to the seat cushion.
[0098] The movement of the second-row seats 104 is driven by seat drive motors. These motors can be positioned separately along the vehicle's front-to-back direction and width direction, or a single drive mechanism combined with a reversing transmission structure can achieve drive in both directions. The first-row seats are located in front of the second-row seats 104, and the third-row seats 105 are located behind them. The second vehicle side door 102 corresponds to the second-row seats 104, the third-row side door 103 corresponds to the third-row seats 105, and the first vehicle side door corresponds to the first-row seats. Sealing covers are used to conceal openings on the vehicle body and can be opened when needed.
[0099] For multi-row vehicles, third-row passengers need to use the access passage corresponding to the third-row side door 103 and the second vehicle side door 102 when getting on and off. The effective width of the access passage is directly constrained by the position of the second-row seats 104. Meanwhile, since the third-row side door 103 is located between the second vehicle side door 102 and the sealing cover, the opening action of the third-row side door 103 is also constrained by the state of adjacent components. When the sealing cover is open, it protrudes at least partially from the vehicle's outer surface. If the third-row side door 103 opens under these conditions, there is a risk of interference with the open sealing cover. Furthermore, the third-row side door 103 and the second vehicle side door 102 need to maintain a predetermined timing and gap during opening and closing to avoid interference between the two doors.
[0100] To address the aforementioned constraints, in this embodiment of the invention, the opening of the third-row side door 103 is controlled by responding to multiple opening signals and interlocking the state of the sealing cover, and the second-row seats 104 are adjusted in conjunction to provide a passage for third-row passengers to get on and off the vehicle.
[0101] like Figure 1 As shown, the door control method provided in this embodiment of the invention includes the following steps:
[0102] S101, Receive door opening request signal;
[0103] The door opening request signals include a first opening signal, a second opening signal, a third opening signal, and a fourth opening signal.
[0104] The first opening signal is used to request the opening of the second vehicle side door 102, the second opening signal is used to request the opening of the third row side door 103, the third opening signal is used to request the simultaneous opening of the second vehicle side door 102 and the third row side door 103, and the fourth opening signal is used to request the opening of the third row side door 103 alone. The triggering sources or triggering methods of the first, second, third, and fourth opening signals are different.
[0105] S102. Determine the type of opening signal; that is, determine whether the received door opening request signal is the first opening signal, the second opening signal, the third opening signal, or the fourth opening signal, so as to perform the corresponding door opening action according to the type of opening signal.
[0106] S103, Perform the door opening action;
[0107] Based on the determination result of the opening signal type, execute the door opening action corresponding to the door opening request signal.
[0108] If the opening signal type is the first opening signal, control the second vehicle side door 102 to open to the preset opening position, and keep the third row side door 103 in the closed state.
[0109] If the opening signal type is the second opening signal, the third row side door 103 is prohibited from being opened when the sealing cover is in the open state; when the sealing cover is in the closed state, the third row side door 103 is opened only after confirming that the second vehicle side door 102 has been opened.
[0110] If the opening signal type is the third opening signal, the third row side door 103 is prohibited from being opened when the sealing cover is in the open state; when the sealing cover is in the closed state, the second vehicle side door 102 and the third row side door 103 are controlled to open simultaneously.
[0111] Specifically, such as Figures 2 to 4 As shown, the door control method provided in this embodiment of the invention includes:
[0112] In response to the first opening signal, the second vehicle side door 102 is controlled to open to the preset opening position, while the third row side door 103 remains closed;
[0113] In response to the second opening signal, the third row side door 103 is prohibited from being opened when the sealing cover is in the open state; when the sealing cover is in the closed state, the third row side door 103 is opened only after confirming that the second vehicle side door 102 has been opened.
[0114] In response to the third opening signal, when the sealing cover is in the open state, the opening of the third row side door 103 is prohibited; when the sealing cover is in the closed state, the opening of the second vehicle side door 102 and the third row side door 103 is controlled to open simultaneously.
[0115] In this embodiment of the invention, to address the issues of insufficient safety and poor comfort for passengers getting on and off in the third row of multi-row vehicles, multiple opening signals are set up to correspond to different door opening methods, and the state of the sealing cover is used as a prerequisite for judging the opening of the third-row side door 103, thereby controlling the opening process of the third-row side door 103.
[0116] The third-row side door 103 is located between the second vehicle side door 102 and the sealing cover. When the sealing cover is open, it protrudes from the outer surface of the vehicle body. If the third-row side door 103 is opened at this time, there is a risk of collision interference between the two. In this embodiment of the invention, the state of the sealing cover is first determined when responding to the second and third opening signals. When the sealing cover is in the open state, the opening of the third-row side door 103 is prohibited. This interference risk is eliminated from the control logic, and the problem of lack of linkage judgment of the state of adjacent components when opening the door is solved.
[0117] Upon response to the second opening signal, the second vehicle side door 102 opens first, followed by the third-row side door 103 after confirmation. The opening sequence of the two doors is fixed, and the access passage for third-row passengers is already formed when the third-row side door 103 opens. Third-row passengers will not enter or exit the vehicle through the third-row side door 103 if the access passage is not yet formed. The formed access passage reduces the restriction on the body posture of third-row passengers when entering and exiting the vehicle, and passengers can enter and exit the vehicle more comfortably. Safety is guaranteed while comfort is improved simultaneously.
[0118] When the third opening signal is received, both doors open simultaneously. Under the premise of ensuring safety through interlock judgment, the total time for opening the front and rear doors is shortened, reducing the waiting time for third-row passengers and achieving a balance between safety and efficiency.
[0119] When the first opening signal is received, only the second vehicle side door 102 opens to the preset opening position, while the third-row side door 103 remains closed. When second-row passengers get on and off the vehicle normally, the third-row side door 103 does not move with the opening of the second vehicle side door 102, thus avoiding unnecessary opening of the third-row side door 103.
[0120] By setting up the above multiple door opening methods, different getting on and off scenarios can be adapted. The interlock judgment of the sealing cover and the timing control between the front and rear doors ensure opening safety, while the simultaneous opening of the front and rear doors takes into account efficiency. The safety and comfort of third-row passengers getting on and off the vehicle are improved.
[0121] In embodiments of the present invention, such as Figure 2 As shown, in response to the first enable signal, steps S201 to S202 are executed.
[0122] S201, in response to a first opening signal; the first opening signal is used to request the opening of the second vehicle side door 102;
[0123] S202, Control the second vehicle side door 102 to open to the preset opening position.
[0124] Upon responding to the first opening signal, the second vehicle side door 102 is opened to a preset opening position, while the third-row side door 103 remains closed. When second-row passengers are getting on and off the vehicle normally, the third-row side door 103 does not move in response to the first opening signal; the door opening action corresponds to the actual needs of the passengers.
[0125] In embodiments of the present invention, such as Figure 3 As shown, in response to the second enable signal, steps S301 to S302 are executed.
[0126] S301, in response to a second opening signal; the second opening signal is used to request the opening of the third row of side doors 103;
[0127] S302. Control the opening and closing states of the second vehicle side door 102 and the third row side door 103 according to the opening and closing state of the sealing cover.
[0128] Specifically, when the sealing cover is open, the third-row side door 103 is prohibited from being opened; when the sealing cover is closed, the third-row side door 103 is opened only after confirming that the second vehicle side door 102 is open. Therefore, the opening process corresponding to the second opening signal is a sequential opening process: the second vehicle side door 102 opens first, forming the passageway for third-row passengers to get on and off; after the third-row side door 103 opens, it facilitates the entry and exit of third-row passengers. Whether the second vehicle side door 102 and the third-row side door 103 are open can be detected and confirmed by door lock position sensors installed on the second vehicle side door 102 and the third-row side door 103, respectively.
[0129] In embodiments of the present invention, such as Figure 4 As shown, in response to the third enable signal, steps S401 to S402 are executed.
[0130] S401, in response to a third opening signal; the third opening signal is used to request the opening of the third-row side door 103, and the difference between the third opening signal and the second opening signal is that the opening sequence of the two doors is different.
[0131] S402. Control the opening and closing states of the second vehicle side door 102 and the third row side door 103 according to the opening and closing state of the sealing cover.
[0132] Specifically, when the sealing cover is open, the third-row side door 103 is prohibited from being opened; when the sealing cover is closed, the second vehicle side door 102 and the third-row side door 103 are opened simultaneously. Therefore, the opening process corresponding to the third opening signal is a simultaneous opening process for the second vehicle side door 102 and the third-row side door 103, thus shortening the total time required for the second vehicle side door 102 and the third-row side door 103 to fully open.
[0133] In this embodiment of the invention, the state of the sealing cover is detected by at least one of the following methods. The first method is to acquire a microswitch signal of the sealing cover. The microswitch is linked to the opening and closing action of the sealing cover; when the sealing cover is open, the microswitch outputs a switch signal indicating an open state, and when the sealing cover is closed, it outputs a switch signal indicating a closed state. The second method is to detect a detection signal from a position sensor of the sealing cover. The position sensor is used to detect the opening degree or position of the sealing cover relative to the vehicle body. The third method is to communicate with the control module to acquire the state of the sealing cover. The above three methods can be used individually or in combination to improve the reliability of the state determination.
[0134] like Figure 8 and Figure 9As shown, the door control method of this embodiment of the invention further includes:
[0135] In response to a second or third opening signal, when the sealing cover is in the open state, the opening of the third row side door 103 is prohibited, and a first prompt message is issued, prompting the sealing cover to be closed.
[0136] The first prompt message can be presented in at least one of the following forms: dashboard display, indicator light flashing, or sound prompt, to guide the user to close the sealing cover in a timely manner. After the sealing cover is closed, the user can request to open the third-row side door 103 again.
[0137] In embodiments of the present invention, such as Figure 9 As shown, in response to the third opening signal, the second vehicle side door 102 and the third row side door 103 are controlled to open simultaneously, including:
[0138] First, control the second vehicle side door 102 to open to the first preset angle;
[0139] After the second vehicle side door 102 is opened to the first preset angle, the third row side door 103 is controlled to unlock and open, and the second vehicle side door 102 continues to be opened synchronously.
[0140] The first preset small angle is less than the angle corresponding to the second vehicle side door 102 when it is fully opened. Specifically, in one embodiment, the first preset small angle is 5 degrees; in another embodiment, the first preset small angle can be taken in the range of 5 degrees to 10 degrees. The specific value of the first preset small angle can be determined according to the vehicle model layout, and is not specifically limited here.
[0141] After the second vehicle side door 102 opens to the first preset angle, it can provide clearance for the unlocking and opening of the third-row side door 103, avoiding interference between the two doors in the initial opening stage; then the two second vehicle side doors 102 and the third-row side door 103 open simultaneously, which can shorten the total time for opening the two doors while ensuring safety.
[0142] In embodiments of the present invention, such as Figure 9 As shown, during the process of controlling the simultaneous opening of the second vehicle side door 102 and the third row side door 103, the relative distance between the second vehicle side door 102 and the third row side door 103 is monitored in real time.
[0143] If the relative distance between the second vehicle side door 102 and the third row side door 103 is less than a preset safety threshold, the opening speed of at least one side door will be dynamically adjusted, or the opening action of one side door will be suspended, until the relative distance between the second vehicle side door 102 and the third row side door 103 is greater than or equal to the preset safety threshold.
[0144] Specifically, in one embodiment, during the simultaneous opening of the second vehicle side door 102 and the third row side door 103, a distance sensor monitors the relative distance between the second vehicle side door 102 and the third row side door 103 in real time. If the relative distance between the second vehicle side door 102 and the third row side door 103 is less than a preset safety threshold, the opening speed of at least one door is dynamically adjusted, or the opening action of one door is paused, until the relative distance between the second vehicle side door 102 and the third row side door 103 is greater than or equal to the preset safety threshold. For example, the opening speed of the third row side door 103 is dynamically reduced, or the opening action of one of the doors is temporarily paused, and the opening continues after the relative distance is restored.
[0145] Finally, the second vehicle side door 102 and the third row side door 103 each reach their respective preset opening positions, achieving coordinated opening of both doors.
[0146] In embodiments of the present invention, such as Figure 6 , Figure 8 and Figure 9 As shown, the door control method also includes:
[0147] In response to a second or third opening signal, the second-row seats 104 are adjusted according to the seat linkage adjustment strategy before the third-row side door 103 is opened.
[0148] In other words, regardless of whether the user requests to open the two doors sequentially via the second opening signal or requests to open the two doors simultaneously via the third opening signal, the control module adjusts the position of the second-row seats 104 before controlling the third-row side door 103 to open, so that the access passage is already formed when the third-row side door 103 is opened.
[0149] Furthermore, according to the seat linkage adjustment strategy, the second-row seat 104 is adjusted, specifically including the following steps:
[0150] First, obtain the occupancy status type and current position information of the second row seat 104; the occupancy status type includes no passengers on the second row seat 104 and passengers on the second row seat 104;
[0151] Then, the corresponding linkage adjustment method is determined according to the occupancy status type; different occupancy status types result in different linkage adjustment methods, which will be explained in detail in subsequent embodiments.
[0152] Then, according to the determined linkage adjustment method, the position and / or backrest angle of the second row seat 104 are adjusted;
[0153] Finally, after adjusting the second-row seats 104 to the target position and / or target backrest angle, control the third-row side door 103 to open to the target opening position. The target opening position can be the same as the aforementioned preset opening position. This step defines the sequence between seat adjustment and the opening of the third-row side door 103, that is, the third-row side door 103 is opened only after the seat adjustment is completed, ensuring that the passage between the two rows of seats is formed when the third-row side door 103 is opened.
[0154] The occupancy status type indicates whether there is a passenger on the corresponding seat. Occupancy status types include two categories: no passenger on the seat and passenger on the seat. The occupancy status type can be detected by the occupancy detection sensor 2031 installed on the seat. The current position information indicates the position of the second-row seat 104 in the fore-and-aft direction and the position in the width direction of the vehicle body, and is detected by the seat position sensor. The control module determines the starting point of seat adjustment based on the current position information and calculates the amount of movement accordingly. Simultaneously, it monitors whether the second-row seat 104 has reached the target position during the adjustment process.
[0155] When the third-row side door 103 is unlocked or open, the second-row seats 104 remain in the position after the seat linkage adjustment action. The seat linkage adjustment action refers to the position or backrest angle adjustment action performed on the second-row seats 104 according to the seat linkage adjustment strategy. Throughout the entire period of third-row passenger alighting and alighting, the second-row seats 104 remain in a yielding position to ensure that the aisle for alighting and alighting remains at the adjusted width.
[0156] The movement distance of the second-row seat 104 or the forward rotation angle of the second-row seat 104 during the seat linkage adjustment is an adjustable parameter determined by the control module based on a preset position or learned from historical usage habits. In one embodiment, the control module determines the movement distance of the second-row seat 104 according to a pre-calibrated preset position, and the preset position and preset angle are written into the control module during vehicle calibration. In another embodiment, the control module records historical usage habits, such as records of passengers manually correcting their seat positions after linkage adjustment, and uses the corrected position as the learning result. During subsequent linkage adjustments, the movement distance of the second-row seat 104 or the forward rotation angle of the second-row seat 104 is determined according to the learning result, so that the adjustment gradually conforms to the passenger's usage habits.
[0157] Furthermore, such as Figure 8 As shown, the corresponding linkage adjustment method is determined according to the occupancy status type, specifically including:
[0158] If there are no passengers in the second row of seats 104, the corresponding linkage adjustment mode is set to the first linkage adjustment mode.
[0159] In embodiments of the present invention, such as Figure 8As shown, the first linkage adjustment method specifically includes:
[0160] The second-row seats 104 are moved forward along the front-rear direction of the vehicle body to the mechanical limit position, and the second-row seats 104 are moved inward along the width direction of the vehicle body to the limit position.
[0161] When there are no passengers in the second-row seats 104, the seats do not need to consider the seating posture and can be adjusted to their maximum range. The second-row seats 104 are moved forward along the vehicle's longitudinal direction to their mechanical limit, that is, moved forward to the maximum allowable position by the front limit of the slide rail assembly; simultaneously, the second-row seats 104 are moved inward along the vehicle's width direction to their innermost position, that is, moved inward to the innermost position allowed by the vehicle's width direction. Through this first linkage adjustment, the degree of accommodation of the second-row seats 104 is maximized, and the width of the passageway for getting in and out between the second-row seats 104 and the third-row seats 105 is maximized.
[0162] In embodiments of the present invention, such as Figure 8 As shown, the first linkage adjustment method also includes:
[0163] While moving the second-row seat 104 to its mechanical limit position, the backrest of the second-row seat 104 is tilted forward to a horizontal or nearly horizontal flat position.
[0164] Folding the backrests of the second-row seats 104 forward can further free up the space occupied by the second-row seats 104 above the aisle for getting in and out of the vehicle. In conjunction with the forward and inward movement of the seats, it can maximize the space-saving effect and further improve the comfort of getting in and out of the third-row passengers.
[0165] Furthermore, such as Figure 8 As shown, the corresponding linkage adjustment method is determined according to the occupancy status type, which specifically includes:
[0166] If there are passengers in the second row of seats 104, the corresponding linkage adjustment mode is set to the second linkage adjustment mode.
[0167] In embodiments of the present invention, such as Figure 8 As shown, the second linkage adjustment method specifically includes:
[0168] Move the second-row seat 104 forward a first preset distance along the front-rear direction of the vehicle body, and move the second-row seat 104 inward a second preset distance along the width direction of the vehicle body.
[0169] The first preset distance is less than the movable travel of the second-row seat 104 along the front-rear direction of the vehicle body, and the second preset distance is greater than or equal to zero. Among them, the movable travel is the maximum distance that the second-row seat 104 can be adjusted along the front-rear direction of the vehicle body, that is, the distance that the seat travels on the slide rail assembly from the rearmost position (mechanical limit rear position) to the frontmost position (mechanical limit front position).
[0170] In one embodiment, the movable travel of the second-row seat 104 of a certain vehicle model is 200 mm. The first preset distance in the second linkage adjustment method can be 50% of the movable travel, i.e., 100 mm; the second preset distance can be zero, i.e., no movement in the width direction, or it can be a smaller value to achieve a slight inward movement of the second-row seat 104 towards the inside of the vehicle. The first preset distance and the second preset distance together define the target position reached by the second-row seat 104 after adjustment.
[0171] The first preset distance is less than the movable travel, ensuring that even when passengers are on the second-row seats 104, a gap remains between the seats and the in front structure after the seats are moved forward, thus accommodating the legroom of the second-row passengers. The second preset distance is greater than or equal to zero, allowing the width-direction clearance to be flexibly configured according to the vehicle's layout. Therefore, the second linkage adjustment method creates a passageway for third-row passengers while avoiding excessive encroachment on the seating space of second-row passengers. The second linkage adjustment method also includes controlling the backrest of the second-row seats 104 to tilt forward moderately, for example, at an angle of approximately 10 degrees, to avoid excessively affecting the seating posture of second-row passengers while reducing the obstruction of the rear access passageway by the backrest.
[0172] As the second-row seats 104 move forward and the backrests recline forward, the control module issues a voice prompt through the vehicle's audio system. The voice prompt may specifically state: "Adjusting seats for third-row passengers, please maintain your posture," to remind second-row passengers to keep their posture.
[0173] In embodiments of the present invention, such as Figure 7 and Figure 8 As shown, according to the seat linkage adjustment strategy, the second-row seat 104 is adjusted, which also includes:
[0174] The second-row seats 104 are monitored in real time during movement. The running resistance includes resistance along the front-to-back direction of the vehicle body and resistance along the width direction of the vehicle body.
[0175] When the detected running resistance exceeds the preset threshold, the second row seat 104 is controlled to stop moving and is controlled to retract a fixed distance in the opposite direction of movement, while a second prompt message is issued.
[0176] During the movement of the second-row seats 104, the running resistance can be obtained by detecting the current of the drive motor of the seat drive mechanism. The control module monitors the current change of the drive motor in real time to calculate the running resistance.
[0177] In one implementation, when the resistance of the second-row seat 104 along the front-to-back direction or along the width direction of the vehicle body exceeds 1.5 times the normal operating resistance of the second-row seat 104, it is determined that the operating resistance exceeds a preset threshold. When the detected operating resistance exceeds the preset threshold, the second-row seat 104 is controlled to stop moving and is controlled to retract a fixed distance in the opposite direction of movement. The fixed distance is a preset retraction amount, for example, it can be set to 10% of the forward travel distance. At the same time, a second prompt message is issued. The second prompt message is used to indicate that the seat movement is obstructed. For example, the content of the second prompt message can be: "Seat movement is obstructed, please clear the obstacle." This can be communicated to the user through the instrument display or voice broadcast, informing them that the seat movement is obstructed and requesting the removal of the obstacle. After the user confirms or the obstacle is cleared, the adjustment can be attempted again.
[0178] In embodiments of the present invention, such as Figure 5 As shown, the door control method also includes:
[0179] In response to the fourth opening signal and when the vehicle is in a preset emergency state, the third-row side door 103 is opened independently without detecting the status of the sealing cover.
[0180] Specifically, the fourth opening signal is used to request the separate opening of the third-row side door 103. The preset emergency state determination conditions can be pre-set by the vehicle designers according to the vehicle model requirements. The control module determines whether the vehicle is in a preset emergency state based on the vehicle status signal. For example, the preset emergency state can be a vehicle collision, and the vehicle status signal can include the detection signal from the collision sensor.
[0181] In normal operation, the opening of the third-row side door 103 is constrained by the state of the sealing cover and the opening state of the second vehicle side door 102. However, in the preset emergency state, the above constraints are released, the control module no longer detects the current state of the sealing cover, and the third-row side door 103 opens directly and independently. Even if the second vehicle side door 102 is not open, it does not obstruct the opening of the third-row side door 103, thereby ensuring the unobstructed passage of the third-row escape route in an emergency.
[0182] In embodiments of the present invention, such as Figure 5 As shown, the door control method also includes:
[0183] In response to the fourth opening signal and when the vehicle is not in a preset emergency state, the individual opening action of the third-row side door 103 is refused, and a third prompt message is issued, which instructs the second vehicle side door 102 to be opened first.
[0184] In non-emergency situations, the fourth opening signal is rejected to prevent accidental triggering that could lead to the unintended opening of the third-row side door 103. At the same time, the third prompt message guides the user to follow the normal procedure of opening the second vehicle side door 102 first.
[0185] In this embodiment of the invention, the door control method further includes:
[0186] Real-time monitoring of vehicle collision status or body structure damage status;
[0187] When a vehicle collision occurs or the second vehicle side door 102 is damaged, the interlock logic between the second vehicle side door 102 and the third row side door 103 is released, allowing the third row side door 103 to be opened in response to the fourth opening signal.
[0188] The interlock logic is the aforementioned logic that controls the opening of the third-row side door 103 only after confirming that the second vehicle side door 102 has been opened. Collision status can be detected by collision sensors. For example, when a collision is determined or the second vehicle side door 102 cannot be opened due to structural damage, the control module immediately releases the interlock logic between the second vehicle side door 102 and the third-row side door 103, no longer requiring the second vehicle side door 102 to be open before the third-row side door 103 can be opened. Therefore, when the second vehicle side door 102 cannot be opened due to a collision or damage, the release of the interlock logic allows the third-row side door 103 to still serve as an escape route for third-row passengers.
[0189] In this embodiment of the invention, the door control method further includes:
[0190] In response to the first closing signal, the second vehicle side door 102 and / or the third row side door 103 are controlled according to a preset door closing strategy.
[0191] Furthermore, such as Figure 10 As shown, according to the preset door closing strategy, the second vehicle side door 102 and / or the third row side door 103 are controlled, specifically including the following steps:
[0192] S1102. Determine that the current state of the third row side door 103 is fully locked;
[0193] S1103, Control the second vehicle side door 102 to perform a closing operation.
[0194] Specifically, the fully locked state can be detected by a door lock position sensor installed on the third-row side door 103. During the closing process, the door lock typically goes through unlocked, partially locked, and fully locked states. When the third-row side door 103 is detected to be in an intermediate state such as partially locked, it can be considered not fully closed. In this case, the third-row side door 103 must be controlled to close completely and reach the fully locked state before the closing operation of the second vehicle side door 102 is executed. Figure 10 The control strategy corresponds to the scenario where the third-row side door 103 has been closed first, and at this time the object to be closed is only the second vehicle side door 102.
[0195] Furthermore, such as Figure 11 As shown, according to the preset door closing strategy, the second vehicle side door 102 and / or the third row side door 103 are controlled, specifically including the following steps:
[0196] S1202. Determine that the current state of the third row side door 103 is open;
[0197] S1203 If a passenger is detected on the third-row seat 105, the anti-pinch protection function is activated and a warning sound is turned on, and the second vehicle side door 102 and the third-row side door 103 are controlled to perform a linkage closing operation.
[0198] If no passengers are detected in the third row of seats 105, the second vehicle side door 102 and the third row side door 103 will be controlled to close in a coordinated manner without the need to activate the anti-pinch protection or sound an alarm.
[0199] When there are passengers in the third row of seats 105, there is a risk of pinching injury during the closing process. Therefore, the anti-pinch protection function is activated and the warning sound is turned on at the same time as closing the door. The warning sound is used to remind the passengers in the vehicle to pay attention to the closing action.
[0200] Specifically, if the third-row side door 103 is currently open, it means that both the second vehicle side door 102 and the third-row side door 103 are open. At this time, it is further detected whether there are passengers on the third-row seats 105, and the corresponding linkage closing operation is performed according to the detection result.
[0201] If there are passengers in the third row of seats 105, and there is a risk of pinching or injuring the third row passengers during the closing process, the warning sound will be activated first and the anti-pinch protection function will be activated, and then the second vehicle side door 102 and the third row side door 103 will be controlled to perform a linkage closing operation.
[0202] When the alert tone is activated, the controller will control the car audio system to emit a door closing alert tone, such as two "beep" sounds or a voice prompt saying "The door is about to close," to remind third-row passengers to pay attention to the door closing action.
[0203] When the anti-pinch protection function is activated, the control module reduces the closing speed of the third-row side door 103 to 50% of the normal closing speed and limits the maximum torque of the drive motor to 60% of the maximum torque of the drive motor when closing normally, in order to reduce the risk of squeezing during the closing process, and then performs a linkage closing operation.
[0204] Furthermore, during the linkage closing process, if the closing resistance of the third-row side door 103 is detected to exceed a preset threshold, the closing will immediately stop, and the third-row side door 103 will be controlled to open in the opposite direction at a third preset angle, while simultaneously emitting a warning sound. For example, the preset threshold is set to 30N.
[0205] If the closing resistance exceeds the preset threshold twice in a row, the closing action will be paused and a prompt message will be displayed on the central control screen. The prompt message may be: "Please check the third row and close it again after confirming that it is safe." After the user confirms that it is safe, the linkage closing operation will be performed again.
[0206] If there are no passengers on the third-row seats 105, there is no risk of pinching during the closing process. The second vehicle side door 102 and the third-row side door 103 are directly controlled to perform a linkage closing operation without the need to turn on the prompt sound or activate the anti-pinch protection function, making the closing process faster.
[0207] Furthermore, such as Figure 11 As shown, controlling the second vehicle side door 102 and the third row side door 103 to perform a coordinated closing operation specifically includes:
[0208] First, close the third-row side door 103, then close the second vehicle side door 102;
[0209] Alternatively, first control the second vehicle side door 102 to close to the second preset angle, then control the third row side door 103 to close, and finally control the second vehicle side door 102 to close completely;
[0210] Finally, control the second-row seats 104 to reset to their initial state.
[0211] The second preset angle is less than the angle corresponding to the complete closure of the second vehicle side door 102, and its specific value can be pre-calibrated according to the structure of the two doors.
[0212] Both closing sequences ensure that the second vehicle side door 102 remains open enough to allow for observation and avoidance of the third-row side door 103 before the third-row side door 103 is completely closed, thus preventing interference between the two doors during the closing process.
[0213] In embodiments of the present invention, such as Figure 12 As shown, the door control method also includes:
[0214] In response to the second closing signal, the third-row side door 103 is controlled to perform a closing operation, while the current state of the second vehicle side door 102 is maintained;
[0215] Finally, control the second-row seats 104 to reset to their initial state.
[0216] If the second-row seat 104 has undergone a seat adjustment action, after the third-row side door 103 closes and locks, the control module will reset the second-row seat 104 to its initial state before the seat adjustment action. The initial state includes the position of the second-row seat 104 in the fore-and-aft direction, its position in the width direction, and its backrest angle. The control module records the initial state before performing the seat adjustment action. After confirming the third-row side door 103 is closed and locked via the door lock sensor, it restores the position and backrest angle of the second-row seat 104 according to the recorded initial state, so second-row passengers do not need to readjust the seats when they re-enter the vehicle.
[0217] The second closing signal is used to request the closing of the third-row side door 103 separately; the second vehicle side door 102 does not operate with the second closing signal.
[0218] In this embodiment of the invention, the door control method further includes:
[0219] When the third-row side door 103 is open, if it is detected that the user manually closes the second vehicle side door 102 and the manual closing speed is lower than the preset speed threshold, the follow-up function is triggered to control the second vehicle side door 102 and the third-row side door 103 to automatically complete the closing action.
[0220] Specifically, during the door closing process, if the third-row side door 103 is open and the system detects that the user is manually closing the second vehicle side door 102, and the closing speed is lower than a preset speed threshold, the follow-up function is triggered, automatically taking over the closing action of the second vehicle side door 102. If the third-row side door 103 is still open at this time, the control module can issue a prompt after the second vehicle side door 102 closes, or further process the situation according to the aforementioned linkage closing logic.
[0221] If the manual closing speed reaches or exceeds the preset speed threshold, the follow-up function will not be triggered, and the control module will allow the user to manually close the door completely. However, after the manual closing is completed, the control module will automatically adjust the second vehicle side door 102 to the preset safe opening angle and then pause, and issue a prompt, waiting for the user's confirmation before closing the third row side door 103.
[0222] In this embodiment of the invention, the door control method further includes:
[0223] When the sensor used to collect the status or position information of the second-row seat 104 malfunctions, the system switches to safety mode, prohibiting any linked adjustment actions of the second-row seat 104 and continuously issuing the first fault warning message. Sensor malfunctions can be identified through signal loss, detection values exceeding the measurement range, or communication interruption. After switching to safety mode, linked seat adjustment actions are disabled to prevent blindly moving the seat when its status is unknown. The first fault warning message continues to be issued to remind the user to have the seat repaired promptly.
[0224] In this embodiment of the invention, the third-row side door 103 can be a swing door, a sliding door, or other openable door type. The specific type is determined according to the vehicle model layout, and the door control method described in the foregoing embodiments is applicable to different door types.
[0225] In one embodiment, the third-row side door 103 is a swing-out door, which adopts an outward swing-out opening structure, providing a larger entry and exit space for third-row passengers.
[0226] The above embodiments describe in detail the door control method provided by the embodiments of the present invention. In a second aspect, the embodiments of the present invention provide a door control system such as... Figure 13 As shown, Figure 13 This is a schematic diagram of a vehicle door control system provided in an embodiment of the present invention. The vehicle door control system includes a signal receiving module 202, a status detection module 203, a drive execution module 204, and a control module 201. The control module 201 is communicatively connected to the signal receiving module 202, the status detection module 203, and the drive execution module 204. The control module 201 has a built-in memory and processor, storing executable computer programs for executing the vehicle door control methods of the above embodiments.
[0227] The signal receiving module 202 is used to receive an opening signal and a closing signal. The opening signal is used to request the opening of the second vehicle side door 102 and / or the third row side door 103, and the closing signal is used to request the closing of the second vehicle side door 102 and / or the third row side door 103.
[0228] In this embodiment of the invention, the opening signal includes a first opening signal, a second opening signal, a third opening signal, and a fourth opening signal. Specifically, the first opening signal is used to request the opening of the second vehicle side door 102; the second opening signal is used to request the opening of the third row side door 103; the third opening signal is used to request the simultaneous opening of both the second vehicle side door 102 and the third row side door 103; and the fourth opening signal is used to request the opening of only the third row side door 103 when the vehicle is in a preset emergency state.
[0229] The closing signals include a first closing signal and a second closing signal. The first closing signal is used to request the simultaneous closing of the second vehicle side door 102 and the third row side door 103; the second closing signal is used to request the individual closing of the third row side door 103.

The fourth open signal can be triggered by the emergency switch located inside the vehicle, and the emergency operation signal receiving unit 2027 is used to receive the emergency operation signal triggered by the emergency switch.
[0234] like Figure 17 As shown, the status detection module 203 includes an occupancy detection sensor 2031, a seat position sensor 2032, a seat movement resistance detection sensor 2033, a door lock position sensor 2034, and a collision sensor 2035.
[0235] The occupancy detection sensor 2031 is used to detect the occupancy status of the second-row seats 104 and the third-row seats 105. For example, the occupancy detection sensor 2031 may include a pressure sensor disposed under the seat cushion of the second-row seats 104 and an occupancy sensor disposed on the third-row seats 105.
[0236] The seat position sensor 2032 is used to detect the position information of the second-row seat 104.
[0237] The seat movement resistance detection sensor 2033 is used to detect the running resistance of the second-row seat 104 during movement. For example, the seat movement resistance detection sensor 2033 can be a current detection module, which determines the running resistance of the second-row seat 104 by detecting the current of the drive motor of the second-row seat 104.
[0238] The door lock position sensor 2034 is used to detect the door lock position information of the second vehicle side door 102 and the third row side door 103 to determine the locking status of the two doors. For example, after the third row side door 103 is closed, the door lock position sensor 2034 confirms whether the third row side door 103 has been closed and locked.
[0239] The collision sensor 2035 is used to detect whether a collision has occurred. The detection signal from the collision sensor 2035 can be used as a basis for determining whether the vehicle is in a preset emergency state.
[0240] Furthermore, such as Figure 17 As shown, the state detection module 203 also includes a door opening angle sensor 2036 and a distance sensor 2037. The door opening angle sensor 2036 is used to detect the opening angle of the second vehicle side door 102 and the third row side door 103; the distance sensor 2037 is used to detect the relative distance between the second vehicle side door 102 and the third row side door 103 in real time, for example, to monitor the relative distance between the two doors in real time when both doors are opened simultaneously.
[0241] like Figure 19 As shown, the drive execution module 204 includes a second-row seat drive mechanism 2041, a second side door drive mechanism 2042, and a third side door drive mechanism 2043.
[0242] The second-row seat drive mechanism 2041 includes an X-axis sliding motor for driving the second-row seat 104 to move along the front-rear direction of the vehicle body, a Y-axis sliding motor for driving the second-row seat 104 to move along the width direction of the vehicle body, and a backrest angle adjustment motor for adjusting the backrest angle of the second-row seat 104, so as to perform the linkage adjustment of the second-row seat 104 when the third-row passengers request to get on or off the vehicle, and to perform the reset of the second-row seat 104.
[0243] The second side door drive mechanism 2042 includes a second door drive motor and a second door lock motor. The second door drive motor is used to drive the opening and closing of the second vehicle side door 102, and the second door lock motor is used to drive the unlocking and locking of the door lock of the second vehicle side door 102.
[0244] The third side door drive mechanism 2043 includes a third door drive motor and a third door lock motor. The third door drive motor is used to drive the opening and closing of the third row side door 103, and the third door lock motor is used to drive the unlocking and locking of the door lock of the third row side door 103.
[0245] The solution provided by the embodiments of the present invention has at least the following effects:
[0246] First, by setting the response strategies for the first, second, third, and fourth opening signals, users can choose to open the second vehicle side door 102 individually, open the two doors sequentially, or open the two doors simultaneously, depending on the actual scenario. The door opening method matches the actual needs of passengers getting on and off the vehicle.
[0247] Secondly, by setting an interlock strategy between the state of the sealing cover and the opening action of the third-row side door 103, the opening of the third-row side door 103 is prohibited when the sealing cover is in the open state, and a first prompt message is issued, which can eliminate the risk of interference between the third-row side door 103 and the open sealing cover.
[0248] Third, during the simultaneous opening of the second vehicle side door 102 and the third row side door 103, the second vehicle side door 102 opens to the first preset angle first and then opens synchronously with the third row side door 103. At the same time, the relative distance between the two doors is monitored in real time and the door opening is dynamically adjusted, which can take into account both door opening efficiency and safety.
[0249] Fourth, by controlling the linkage adjustment of the seats, when there are no passengers on the second-row seats 104, the seats move to the mechanical limit position or the position within the limit and the backrest is tilted back, which can maximize the degree of space clearance; when there are passengers on the second-row seats 104, the seats move forward by a preset distance, which makes room for the passage while taking into account the legroom of the second-row passengers.
[0250] Thirdly, such as Figure 14 As shown, this embodiment of the invention also provides a vehicle 100, including a door control system 200 with the above-described structure. The vehicle 100 is a model equipped with three rows of seats. Since the vehicle 100 of this embodiment includes the door control system 200 and the corresponding door control method described in the above embodiments, it possesses all the advantages of the aforementioned door control system 200 and door control method.
[0251] 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.
