Description

Technical Field

[0001] This invention belongs to the field of vehicle seat control, specifically relating to a method, system, and vehicle for controlling second-row seat courtesy and welcoming behavior. Background Technology

[0002] To facilitate boarding and alighting for second-row passengers, the common practice is to move the front passenger seat forward slightly and rotate its backrest forward at a certain angle to create more space for them. However, when multiple passengers are in the second row and the left rear door cannot be opened for safety reasons (e.g., when a left-hand drive vehicle is parked on the side of the road and there is potential for other vehicles to pass), passengers on the left side of the second row must enter through the right-hand door, crouching and moving along the second-row seats to their seats, resulting in a relatively poor user experience. Furthermore, the current solution also presents inconvenience when second-row passengers are elderly or have knees that are unable or difficult to bend due to fractures, falls, or other surgeries. Currently, some vehicles use welfare seats installed in the original right-hand second-row seats to meet the needs of passengers with special needs; however, welfare seats are complex in structure, expensive, and prone to malfunction. Therefore, improving the user experience by utilizing the second-row seats to meet the needs of passengers with special needs is a direction worth exploring. Summary of the Invention

[0003] The purpose of this invention is to provide a method, system, and vehicle for controlling the second-row seats to give way to passengers, so as to realize the function of the second-row seats to give way to passengers and facilitate passengers on the left side of the second row to get on and off the vehicle.

[0004] The second-row seats in this invention include: a second-row left seat cushion that can move laterally, a second-row left backrest that corresponds to and is independent of the second-row left seat cushion, a second-row right seat cushion that can rotate, and a second-row right backrest that corresponds to and is independent of the second-row right seat cushion.

[0005] In a first aspect, the present invention provides a second-row seat courtesy and welcome control system, which includes:

[0006] The left drive unit is used to move the left seat cushion of the second row along the second row transverse slide rail. Driven by the left drive unit, the left seat cushion of the second row can move to the right along the second row transverse slide rail to the right side of the second row seat, and can also move to the left along the transverse slide rail to the reset state (i.e., back to the left side of the second row seat).

[0007] The right drive unit is used to drive the second-row right seat cushion to rotate around a horizontal axis located at the front edge of the second-row right seat cushion. Driven by the right drive unit, the second-row right seat cushion can rotate forward around the horizontal axis to the correct position, and can also rotate backward around the horizontal axis to the reset position (i.e., return to the right side of the second row seat).

[0008] The passenger-side drive is used to move the passenger seat forward and backward.

[0009] The controller acquires signals from the CAN bus and controls the operation of the left driver, right driver, and passenger driver.

[0010] The left travel switch is used to detect whether the left seat cushion of the second row is in the reset state and transmits the detection result to the controller.

[0011] The right limit switch is used to detect whether the left seat cushion of the second row is in the right seat position of the second row and transmits the detection result to the controller.

[0012] The passenger side limit switch is used to detect whether the passenger seat is in a preset avoidance position and transmits the detection result to the controller.

[0013] The positive limit switch is used to detect whether the right seat cushion of the second row is in the correct position and transmits the detection result to the controller.

[0014] The reverse limit switch is used to detect whether the right seat cushion of the second row is in the reset state and transmits the detection result to the controller.

[0015] The right seat cushion sensor is used to detect whether there is anyone on the right seat cushion in the second row and transmits the detection result to the controller.

[0016] The prompt module is used to provide voice prompts under the control of the controller.

[0017] Preferably, the second-row seat courtesy and welcome control system further includes:

[0018] The "Leave to the Left" and "Leave to the Right" buttons are used to activate the "Leave to the Right" function or to confirm the prompt to move to the right.

[0019] The left and right cancel buttons for yielding are used to cancel the yielding function.

[0020] The left and right opening buttons are used to activate the welcome function or to confirm the backward rotation reset prompt.

[0021] The left and right cancel buttons for welcoming guests are used to cancel the welcoming function.

[0022] Pressing the left-hand-to-the-way button will send a command to activate the courtesy function or a confirmation message indicating a rightward movement, and transmit this message to the controller. Pressing the right-hand-to-the-way button will also send a command to activate the courtesy function or a confirmation message indicating a rightward movement, and transmit this message to the controller.

[0023] Pressing the left cancel button will send a command to cancel the courtesy function and transmit it to the controller; pressing the right cancel button will send a command to cancel the courtesy function and transmit it to the controller.

[0024] Pressing the left welcome button will send a command to activate the welcome function or a confirmation message indicating that the function has been reset by rotating it backward, and then transmit this message to the controller. Pressing the right welcome button will also send a command to activate the welcome function or a confirmation message indicating that the function has been reset by rotating it backward, and then transmit this message to the controller.

[0025] Pressing the left cancel button will send a command to cancel the welcome function to the controller; pressing the right cancel button will send a command to cancel the welcome function to the controller.

[0026] Preferably, the second-row seat courtesy and welcome control system further includes: a front passenger seat sensor for detecting whether there is someone in the front passenger seat and transmitting the detection result to the controller; and a front passenger seat movement button for manually pressing to issue a front passenger seat movement command and transmitting it to the controller.

[0027] Secondly, the present invention provides a method for controlling the courtesy and welcome of guests by second-row seats, employing the aforementioned second-row seat courtesy and welcome control system; the method includes:

[0028] Upon receiving the command to activate the courtesy function and meeting the activation conditions, the system checks whether the second-row right seat cushion is in the correct position. If so, after the second-row right-side door is open or the rightward movement prompt is confirmed, the system controls the left drive to move the second-row left seat cushion to the right and onto the second-row right-side seat. The control prompt module then provides a voice prompt indicating that the courtesy movement is complete. If not, the system first controls the right drive to rotate the second-row right seat cushion forward to the correct position. Then, after the second-row right-side door is open or the rightward movement prompt is confirmed, the system controls the left drive to move the second-row left seat cushion to the right and onto the second-row right-side seat. The control prompt module then provides a voice prompt indicating that the courtesy movement is complete.

[0029] Upon receiving the welcome function activation command and meeting the activation conditions, the system first controls the left drive to move the second-row left seat cushion (from the second-row right seat) to the left to the reset state (i.e., back to the second-row left seat). Then, it checks whether the rearward rotation reset prompt is confirmed within a third preset time. If confirmed, the system controls the right drive to rotate the second-row right seat cushion to the reset state (i.e., back to the second-row right seat), and the prompt module provides a voice prompt indicating that the second-row seats have completed the welcome function. Otherwise, the system directly provides a voice prompt indicating that the second-row seats have completed the welcome function.

[0030] Preferably, if conditions 1a, 1b, 1c, 1d, and 1e are met simultaneously, it means that the conditions for activating the courtesy function are met.

[0031] If conditions 1a, 1b, 1d, and 1f are met simultaneously, it means that the conditions for activating the welcoming function are met.

[0032] Among them, condition 1a: the vehicle is in P gear; condition 1b: the left door of the second row is closed; condition 1c: there is no one on the right seat cushion of the second row; condition 1d: the front passenger seat is in the preset avoidance position; condition 1e: the left seat cushion of the second row is located on the left side of the second row; condition 1f: the left seat cushion of the second row is located on the right side of the second row.

[0033] To ensure passenger safety, the vehicle must be in Park (P) as one of the conditions for activating the courtesy and welcome functions. To prevent passengers from accidentally falling out of the vehicle while the second-row left seat cushion slides, the second-row left door must be closed as one of the conditions for activating the courtesy and welcome functions. Since the second-row right seat cushion needs to rotate, it must be empty as one of the conditions for activating the courtesy function to ensure passenger safety. To ensure that the second-row right seat cushion can rotate forward to its final position without bumping or interfering with the front passenger seat, there must be sufficient space in front of the second-row right seat cushion; therefore, the front passenger seat must be in a preset avoidance position as one of the conditions for activating the courtesy and welcome functions.

[0034] Preferably, upon receiving a command to activate the courtesy function: if the vehicle is not in Park (P) gear, the control prompt module will issue a voice prompt stating, "Incorrect gear, second-row courtesy function cannot be activated." If the second-row left door is open, the control prompt module will issue a voice prompt stating, "Please close the second-row left door before activating the second-row courtesy function." If someone is on the second-row right seat cushion, the control prompt module will issue a voice prompt stating, "Someone is on the second-row right seat cushion, second-row courtesy function cannot be activated." If the second-row left seat cushion is not in the second-row left seat area, the control prompt module will issue a voice prompt stating, "Second-row courtesy function is malfunctioning and cannot be activated." These voice prompts inform the user of the specific reason why the courtesy function cannot be activated, allowing the user to take appropriate remedial measures.

[0035] Upon receiving a command to activate the welcome function: If the vehicle is not in Park (P) gear, the control prompt module will issue a voice prompt stating, "Incorrect gear, unable to activate the second-row seat welcome function." If the left second-row door is open, the control prompt module will issue a voice prompt stating, "Please close the left second-row door before activating the second-row seat welcome function." If the left second-row seat cushion is not in the right second-row seat position, the control prompt module will issue a voice prompt stating, "Second-row seat welcome function malfunction, cannot be activated." These voice prompts inform the user of the specific reason why the welcome function cannot be activated, allowing the user to take appropriate remedial measures.

[0036] Preferably, if the front passenger seat is not in the preset clearance position, the system first determines whether there is someone in the front passenger seat. If there is, the control prompt module will issue a voice prompt saying "Please adjust the front passenger seat to the preset clearance position." Upon receiving a front passenger seat movement command within a first preset time, the system will control the front passenger seat driver to move the front passenger seat forward to the preset clearance position. Otherwise, if there is no front passenger seat, the system will directly control the front passenger seat driver to move the front passenger seat forward to the preset clearance position. If there is someone in the front passenger seat, a voice prompt will be issued to solicit the passenger's consent to move the front passenger seat. If the passenger agrees, they will press the front passenger seat movement switch within a first preset time to move the front passenger seat to the preset clearance position. If the passenger does not agree, they will not press the front passenger seat movement button within a first preset time, and the controller will not receive a front passenger seat movement command within the first preset time, at which point the second-row seat courtesy / welcome control will be discontinued. Moving the front passenger seat forward reduces the space occupied by the passenger, causing discomfort. Therefore, asking for their consent via voice prompt takes into account their comfort, resulting in a better experience for the passenger.

[0037] Preferably, when the second-row right-side door is closed, the control prompt module provides a voice prompt: "The second-row right-side door is not open. Please confirm whether to move to the right." If the second-row right-side door is opened within a second preset time or a confirmation message for moving to the right is received within the second preset time (i.e., the right-side movement prompt is confirmed), the left drive unit moves the second-row left seat cushion to the right to the second-row right-side seat, and the control prompt module indicates that the second-row seat has been moved to the right. If the second-row right-side door is not opened within the second preset time and no confirmation message for moving to the right is received (i.e., the right-side movement prompt is not confirmed within the second preset time), the control prompt module provides a voice prompt: "Moving to the right has stopped." When the second-row left seat cushion (from the second-row right-side seat) moves to the left to the reset state (i.e., back to the second-row left-side seat), the control prompt module provides a voice prompt: "Please confirm whether the second-row right seat cushion has rotated back to reset."

[0038] Considering the possibility that a passenger on the left side of the second row might have their knee bent and their leg directly collide with or be crushed by the right-side door during the yielding process, a voice prompt is implemented when the right-side door is closed. The user then determines if this situation exists. If not, the user can confirm and move to the right within a second preset time to continue yielding. If this situation exists and the user does not act within the second preset time, a second voice prompt will say "Stop yielding." If this situation exists, but the user opens the right-side door within the second preset time, the yielding process continues. This double-confirmation method improves the user experience and avoids injury to passengers on the left side of the second row.

[0039] Preferably, when a command to activate the courtesy function is received and the conditions for activating the courtesy function are met, the control prompt module will announce "The courtesy function is about to be activated" via voice; when a command to activate the welcoming function is received and the conditions for activating the welcoming function are met, the control prompt module will announce "The welcoming function is about to be activated" via voice.

[0040] During the forward rotation of the second-row right seat cushion: if a command to cancel the courtesy function is received, the right drive will be controlled to stop rotating the second-row right seat cushion, and the prompt module will be controlled to give a voice prompt "courtesy function canceled".

[0041] During the process of the second-row left seat cushion moving to the right: if a command to cancel the courtesy function is received, the left drive will be controlled to stop the second-row left seat cushion from moving laterally, and the prompt module will be controlled to give a voice prompt "courtesy function canceled".

[0042] During the rearward rotation of the second-row right seat cushion: if a welcome function cancellation command is received, the right drive will be controlled to stop rotating the second-row right seat cushion, and the prompt module will be controlled to give a voice prompt "Welcome function cancelled".

[0043] During the leftward lateral movement of the second-row left seat cushion: if a welcome function cancellation command is received, the left drive will be controlled to stop the lateral movement of the second-row left seat cushion, and the prompt module will be controlled to provide a voice prompt "Welcome function cancelled".

[0044] In the process of yielding / welcoming guests, it can be canceled at any time if special circumstances arise, which expands the flexibility of the yielding / welcoming function and greatly reduces the possibility of accidentally injuring second-row passengers when the seat cushion moves or rotates.

[0045] Thirdly, the present invention provides a vehicle that includes the aforementioned second-row seat courtesy and welcome control system.

[0046] This invention utilizes a second-row seat courtesy and welcome control system to implement a courtesy and welcome function for second-row seats, facilitating boarding and alighting for passengers on the left side of the second row and improving the user experience. Furthermore, the control method incorporates multiple conditions for activating the courtesy / welcome function, ensuring passenger safety during the courtesy and welcome process. In addition, compared to welfare seats, the control method of this invention is simpler, lower in cost, and has a lower probability of seat malfunction. Attached Figure Description

[0060] To gain a more detailed understanding of the features and technical content of the embodiments of the present invention, the implementation of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference and illustration only and are not intended to limit the embodiments of the present invention.

[0061] 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 is for the purpose of describing embodiments of the invention only and is not intended to limit the invention.

[0062] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0063] like Figures 1 to 3 As shown, the second-row seats in this embodiment of the invention include: a second-row left seat cushion 1 capable of lateral movement, a second-row left backrest 3 corresponding to and independent of the second-row left seat cushion 1, a second-row right seat cushion 2 capable of rotation, and a second-row right backrest 4 corresponding to and independent of the second-row right seat cushion 2. The front passenger seat in this embodiment of the invention can move forward or backward.

[0064] like Figures 1 to 4 As shown, the second-row seat courtesy and welcome control system in this embodiment of the invention includes: a left driver 5, a right driver 6, a passenger driver 7, a controller 8, a left limit switch 9, a right limit switch 10, a passenger driver limit switch 11, a forward limit switch 12, a reverse limit switch 13, a right seat cushion sensor 14, and a prompting module 15. The left limit switch 9, right limit switch 10, passenger driver limit switch 11, forward limit switch 12, reverse limit switch 13, and right seat cushion sensor 14 are electrically connected to the controller 8, and the controller 8 is electrically connected to the left driver 5, right driver 6, passenger driver 7, and prompting module 15.

[0065] The left drive 5 is used to drive the second-row left seat cushion 1 to move along the second-row transverse slide rail (mounted on the floor below the second-row seat cushion) under the control of the controller 8. Driven by the left drive 5, the second-row left seat cushion 1 can move to the right along the second-row transverse slide rail to the right side of the second-row seat, and can also move to the left along the transverse slide rail to the reset state (i.e., return to the left side of the second-row seat).

[0066] The right drive unit 6, under the control of the controller 8, drives the second-row right seat cushion 2 to rotate around a transverse axis located at the front edge of the second-row right seat cushion. Driven by the right drive unit 6, the second-row right seat cushion 2 can rotate forward around the transverse axis at the front edge of the second-row right seat cushion to a final position (e.g., rotate 180°–270°), and can also rotate backward around the transverse axis at the front edge of the second-row right seat cushion to a reset position (i.e., return to the right side of the second-row seat). In some embodiments, when the second-row right seat cushion 2 rotates forward 225° and maintains a 45° tilt relative to the vehicle floor, it indicates that it has rotated forward to the final position.

[0067] The passenger drive 7 is used to drive the passenger seat to move back and forth under the control of the controller 8.

[0068] Controller 8 is connected to the CAN bus and can obtain the vehicle gear position signal, the status signal of the left second-row door (i.e., open and closed) and the status signal of the right second-row door (i.e., open and closed) from the CAN bus.

[0069] The left travel switch 9 is used to detect whether the second row left seat cushion 1 is in the reset state and transmits the detection result to the controller 8. In some embodiments, the left travel switch 9 can be installed at the left end of the second row transverse slide rail.

[0070] The right limit switch 10 is used to detect whether the left seat cushion 1 of the second row is in the right seat position of the second row, and transmits the detection result to the controller 8. In some embodiments, the right limit switch 10 can be installed at the right end of the second row transverse slide rail.

[0071] The passenger-side limit switch 11 is used to detect whether the passenger seat is in a preset avoidance position and transmits the detection result to the controller 8. In some embodiments, the right limit switch 10 can be installed on the passenger-side slide rail.

[0072] The positive limit switch 12 is used to detect whether the right seat cushion 2 of the second row is in the correct position and transmits the detection result to the controller 8.

[0073] The reverse limit switch 13 is used to detect whether the second row right seat cushion 2 is in the reset state and transmits the detection result to the controller 8.

[0074] The right seat cushion sensor 14 is used to detect whether there is anyone on the right seat cushion 2 in the second row and transmits the detection result to the controller 8.

[0075] The prompting module 15 is used to provide voice prompts under the control of the controller 8.

[0076] In some embodiments, the second-row seat courtesy and welcome control system further includes: a passenger seat sensor 16 and a passenger seat movement button 17; the passenger seat sensor 16 and the passenger seat movement button 17 are electrically connected to the controller 8. The passenger seat sensor 16 is used to detect whether there is a person in the passenger seat and transmit the detection result to the controller 8; the passenger seat movement button 17 is used to manually press to issue a passenger seat movement command and transmit it to the controller 8.

[0077] In some embodiments, the second-row seat courtesy and welcome control system further includes: a courtesy left opening button 18, a courtesy right opening button 19, a courtesy left cancellation button 20, a courtesy right cancellation button 21, a welcome left opening button 22, a welcome right opening button 23, a welcome left cancellation button 24, and a welcome right cancellation button 25. The courtesy left opening button 18, courtesy right opening button 19, courtesy left cancellation button 20, courtesy right cancellation button 21, welcome left opening button 22, welcome right opening button 23, welcome left cancellation button 24, and welcome right cancellation button 25 are all electrically connected to the controller 8. In some embodiments, the courtesy left opening button 18, courtesy left cancellation button 20, and welcome left opening button 22 and welcome left cancellation button 24 are located on the left side of the second row. The courtesy right opening button 19, courtesy right cancellation button 21, and welcome right opening button 23 and welcome right cancellation button 25 are located on the right side of the second row or on the front passenger side, thus making it easier for passengers to operate.

[0078] The "Left-Open" button 18 and "Right-Open" button 19 are used to activate the courtesy function or to confirm the rightward movement prompt. Pressing the "Left-Open" button 18 sends a message confirming the courtesy function activation or the rightward movement prompt to the controller 8. Pressing the "Right-Open" button 19 sends a message confirming the courtesy function activation or the rightward movement prompt to the controller 8. The "Left-Cancel" button 20 and "Right-Cancel" button 21 are used to cancel the courtesy function. Pressing the "Left-Cancel" button 20 sends a message canceling the courtesy function to the controller 8. Pressing the "Right-Cancel" button 21 sends a message canceling the courtesy function to the controller 8. The "Left-Open" button 22 and "Right-Open" button 23 are used to activate the welcome function or to confirm the backward rotation reset prompt. Pressing the "Left-Open" button 22 sends a message confirming the welcome function activation or the backward rotation reset prompt to the controller 8. Pressing the right welcome button 23 sends a welcome function activation command or a confirmation message (reset by rotating backward) to the controller 8. The left welcome button 24 and the right welcome button 25 cancel the welcome function. Pressing the left welcome button 24 sends a welcome function cancellation command to the controller 8. Pressing the right welcome button 25 sends a welcome function cancellation command to the controller 8.

[0079] The second-row right seat cushion 2 rotates forward to its final position, or the second-row right seat cushion 2 is in its final position, making enough room for the second-row left seat cushion 1 to move laterally to the right side of the second-row seat, facilitating passenger seating or alighting. This process is called the second-row seat yielding process, realizing the second-row seat yielding function. Therefore, by Figure 1 → Figure 2 → Figure 3 The process can be called the process of giving up the second row of seats.

[0080] After passengers are seated or alight, the second-row left seat cushion 1 moves laterally to the left to its reset position. If the second-row right seat cushion 2 needs to be reset, it rotates backward to its reset position. If it does not need to be reset, it remains in its original position. This process is called the second-row seat welcoming process, which realizes the second-row seat welcoming function. Therefore, by Figure 3 → Figure 2 → Figure 1 The process can be called the second-row seat welcoming process.

[0081] like Figure 5 , Figure 6 As shown, the second-row seat courtesy control method in this embodiment of the invention is executed by the controller 8, and specifically includes:

[0137] Figure 9 → Figure 10 This illustrates a welcoming application scenario where a passenger 100 on the left seat cushion 1 of the second row cannot bend their knees or finds it inconvenient to bend them, and the space between the left seat of the second row and the driver's seat is insufficient to accommodate the passenger's legs.

[0138] Figure 11 → Figure 12 → Figure 13 This illustrates another welcoming application scenario: if the passenger 100 on the second-row left seat cushion 1 cannot bend their knees or has difficulty bending them, but the space between the second-row left seat and the driver's seat is sufficient to accommodate the passenger's legs, this seating arrangement can be used. The second-row right seat cushion 2 can also be used after it has been reset. Because the second-row right seat cushion 2 maintains a 45° angle with the vehicle floor when rotated forward to its final position, similar to a "leg rest" on the second-row right side seat, it does not hinder the passenger from moving to the second-row left seat using the second-row left seat cushion 1.

[0139] Figure 11 This demonstrates an application scenario after yielding to another passenger. If the passenger on the left seat cushion 1 in the second row cannot bend their knees or finds it inconvenient to bend them, and the space between the left seat in the second row and the driver's seat is insufficient to accommodate the passenger's legs, but the space on the right side is sufficient after the front passenger seat is moved forward to the preset yielding position, then this method of seating can be adopted. The right seat cushion 2 in the second row, as a "leg rest", can also support the passenger's knees and calves.

[0140] Additionally, if the second-row seats are long and have a middle seat cushion and a middle backrest, then the middle seat cushion and the right-side seat cushion are integrated together to form the second-row right seat cushion 2, and the middle backrest and the right-side backrest are integrated together to form the second-row right backrest 4. In this case, the second-row right-side seat refers to the position corresponding to the right-side seat cushion.

[0141] In addition, this invention also provides a vehicle that includes the aforementioned second-row seat courtesy and welcome control system.

[0142] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
