Description

Technical Field

[0001] The present invention relates to a vehicle and a method for controlling the vehicle, and more particularly, to a technology for automatically returning a slidable seat to a certain position. Background Art

[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] Generally, in the case of buses traveling long distances such as city buses and express buses, seats are arranged on both sides of the aisle in the center of the bus body. In most cases, double rows of seats are arranged on both sides of the aisle, and at the rear, 5 seats for 5 passengers are provided. Not all buses have such a structure, and some buses have double rows of seats arranged on one side of the central aisle and single seats arranged on the other side, such as the recent premium buses.

[0004] In the case of long-distance buses such as intercity buses and express buses, since passengers do not move for a long time after getting on the bus, the space of the center aisle is rarely used. Therefore, if this space is used to form a space between seats, the space with adjacent passengers can be widened even with seats of the same size.

[0005] As such, recently, sliding bus seats have been developed that enable larger passengers to travel comfortably without coming into contact with adjacent passengers by moving the seats toward the center aisle, which is a space that is not used during travel of the bus.

[0006] On the other hand, we found that the distance between seats can be ensured by moving the seats toward the aisle, but in the event of a fire or collision in the vehicle, the aisle narrowed by moving the seats may hinder the rapid escape of passengers. Summary of the invention

[0007] The present invention provides a vehicle and a method for controlling the vehicle. Once an accident occurs in the vehicle, the vehicle can automatically return a slidable seat to an original position to ensure an escape route in an emergency.

[0008] Additional aspects of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

[0009] According to one aspect of the present invention, a vehicle includes a vehicle state sensor, a seat control motor and a controller; the vehicle state sensor is configured to detect the vehicle state; the seat control motor is configured to move a slidable seat; and the controller is configured to control the seat control motor to move the slidable seat to a predetermined original position when the vehicle state sensor detects that an accident of the vehicle has occurred. More specifically, the seat control motor is controlled by the controller and is configured to move the slidable seat from a predetermined original position to a predetermined position before an accident of the vehicle occurs.

[0010] The vehicle may be a bus, and the predetermined position corresponds to the aisle side position of the bus. When an accident of the vehicle is detected, the controller may control the seat control motor to move the slidable seat that has moved to the aisle side of the vehicle to the predetermined original position.

[0011] The vehicle may further include a flame detection sensor configured to detect occurrence of a fire in the vehicle. When the flame detection sensor detects occurrence of a fire in the vehicle, the vehicle state sensor may determine that an accident has occurred in the vehicle.

[0012] The vehicle may further include a collision detection sensor configured to detect a collision of the vehicle, and when the collision detection sensor detects a collision of the vehicle, the vehicle state sensor may determine that an accident has occurred in the vehicle.

[0013] The vehicle may further include a speed detector configured to detect a driving speed of the vehicle. When the vehicle state sensor detects that an accident has occurred and the controller determines that the vehicle has stopped based on the driving speed of the vehicle, the controller may control the seat control motor to move the slidable seat to a predetermined original position.

[0014] The vehicle may further include a camera and an acceleration detector, wherein the camera is configured to capture images of the surroundings of the vehicle, and the acceleration detector is configured to detect the driving acceleration of the vehicle.

[0015] The controller may determine whether the vehicle is located on an inclined road having a predetermined or greater slope based on at least one of a captured surrounding image or a detected driving acceleration.

[0016] When an accident of the vehicle is detected, if the vehicle is not located on an inclined road and the vehicle is not overturned, the controller may control the seat control motor to move the slidable seat to a predetermined original position.

[0017] The vehicle may further include an input device configured to receive a slidable seat movement command, and the controller may control the seat control motor based on the received slidable seat movement command to move the slidable seat to a predetermined original position.

[0018] According to another aspect of the present invention, a method for controlling a vehicle may include: detecting an accident of the vehicle by a vehicle state sensor; determining by a controller whether the vehicle is stopped; determining by the controller whether the vehicle is located on an inclined road; determining by the controller whether the vehicle has overturned; when the vehicle is stopped and the vehicle is not located on an inclined road and the vehicle has not overturned, controlling by the controller a sliding seat of the vehicle to move to a predetermined position.

[0019] Controlling the slidable seat to move to the predetermined position may include, when an accident of the vehicle is detected, controlling the slidable seat that has moved to the passage side of the vehicle to move to a predetermined position corresponding to a predetermined original position.

[0020] Detecting an accident of the vehicle may include determining that an accident has occurred in the vehicle when a flame detection sensor detects occurrence of a fire in the vehicle.

[0021] Detecting an accident of the vehicle may include determining that an accident has occurred in the vehicle when a collision detection sensor detects a collision of the vehicle.

[0022] The method for controlling a vehicle may further include: detecting a driving speed of the vehicle by a speed detector; when an accident of the vehicle is detected, determining by a controller whether the vehicle stops based on the detected driving speed, and when the vehicle stops, controlling the seat control motor by the controller to move the slidable seat to a predetermined position.

[0023] The method for controlling a vehicle may further include: photographing the surrounding image of the vehicle by a camera; and detecting the driving acceleration of the vehicle by an acceleration detector.

[0024] The method for controlling a vehicle may further include determining, by the controller, whether the vehicle is located on an inclined road having a predetermined or greater slope and whether the vehicle has overturned based on at least one of a captured surrounding image or a detected driving acceleration.

[0025] The method for controlling a vehicle may further include: when an accident of the vehicle is detected, if the vehicle is not on an inclined road and the vehicle is not overturned, controlling a seat control motor to move the slidable seat to a predetermined position.

[0026] The method for controlling a vehicle may further include: receiving a slidable seat movement command; and controlling the slidable seat to move to a predetermined position based on the received slidable seat movement command.

[0043] Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings.

[0044] Figure 1 The exterior view of a typical bus. Figure 2 FIG. 1 is a schematic diagram showing a seat structure of a bus according to an embodiment of the present invention. Figure 3 for Figure 2 A detailed view of the seat is shown, specifically a stereoscopic view before the seat is moved. Figure 4 for Figure 2 A detailed view of the seat is shown, specifically a stereoscopic view after the seat has been moved. Figure 5 is a control block diagram of a vehicle according to an embodiment of the present invention, and Figure 6 is a flowchart illustrating a method for controlling a vehicle according to another embodiment of the present invention.

[0045] like Figure 1 As shown, a vehicle and a method of controlling the vehicle according to an embodiment of the present invention will be described using a bus 1 as an example. However, the present invention can also be applied to vehicles other than buses.

[0046] Typically, in situations such as Figure 1 In the van of bus 1, such as Figure 2 The two-person seat shown is installed in a bus. Since these two-person seats are usually determined by standard passenger sizes, sitting side by side with a larger passenger will not only bring the shoulders closer together (making the seat uncomfortable), but the seat on either side may be pushed back, which, especially in the summer, will become hot and uncomfortable if sitting too close.

[0047] Therefore, in order to solve this problem, the seats arranged on the bus 1 can be provided with two rows of seats on at least one side of the central channel (which corresponds to the aisle of the bus 1 body).

[0048] In addition, the seat structure of the bus 1 is configured to form a space between the seats by moving one seat toward the central aisle (which is a space that is not used during the travel of the bus 1), so that larger passengers can travel comfortably without contacting adjacent passengers.

[0049] The seat can be implemented in the form of a slidable seat that can move left and right. Specifically, the slidable seat can be operated in a manual manner that can be manually moved by the operation of the user, or in an automatic manner that can automatically move under the control of the controller.

[0050] In the case of the automatic movement type, the seat control motor 150 for moving the seat under the control of the controller 100 may move the slidable seat in a predetermined direction. In addition, the user may move the slidable seat from one side to the other side by inputting a user command.

[0051] refer to Figures 2 to 4 The slidable seat structure of the bus 1 according to one embodiment of the present invention is provided with a double row of seats 50 on at least one side of a passage 60 in the center of the vehicle body. The double row of seats 50 may be configured as: a fixed seat 51 fixed to the bottom surface of the vehicle body, a slidable seat 52 disposed beside the fixed seat 51 and capable of laterally moving, a moving rail 53 for guiding the movement of the slidable seat 52, a guide rail 54 for guiding the movement of the moving rail 53, and a position fixing portion for fixing the position of the slidable seat 52 by fixing the moving rail 53 to the guide rail 54.

[0052] The fixed seat 51 is installed on the window side, and the slidable seat 52 can be installed on the side of the aisle 60 in the center of the vehicle body. In addition, in the case of a general bus 1, the double-row seats 50 are installed on both sides of the central aisle 60, while in a new bus (such as a high-end bus), the double-row seats 50 will be installed on one side of the central aisle 60.

[0053] First, when the slidable seat 52 is in a manually operated form that is manually moved by the user's operation, the position fixing part may include a handle 55, a fastener 56, and a return spring 57; the handle 55 is hinged to a bracket 58 formed below the slidable seat 52; the fastener 56 is connected to the handle 55 and is inserted into the groove of the guide rail 54 through a hole formed in the movable rail 53 to limit the movement of the movable rail 53; one end of the return spring 57 is engaged to the slidable seat 52, and the other end is engaged to the handle 55 to bounce the handle 55.

[0054] In this case, at least two grooves may be formed in the guide rail 54 to change the position of the slidable seat 52. In addition, the grooves of the guide rail 54 and the holes of the moving rail 53 may be formed to be inclined in the lateral direction to facilitate the entry and exit of the fastener 56.

[0055] The structure of the slidable seat 52 of the bus 1 can promote the convenience of the passengers by moving the slidable seat 52 a predetermined distance from the fixed seat 51 when the bus 1 is traveling.

[0056] When the slidable seat 52 is implemented in an automatic moving form capable of automatically moving under the control of the controller 100, as Figure 3 and Figure 4 As shown, the moving rail 53 moves leftward and rightward along the guide rail 54 by the driving of the seat control motor 150 according to the control command of the controller 100, so that the slidable seat 52 can move in a predetermined direction.

[0057] That is, the user does not manually move the slidable seat 52 by operating the handle 55 , but the user inputs a movement command of the slidable seat 52 through the input device 130 or under the judgment of the controller 100 , and the slidable seat 52 can be automatically moved.

[0058] When passengers board the bus 1, the slidable seats 52 of the double-row seats 50 are fitted with the fixed seats 51 to provide enough space for the passage 60 to allow passengers to move through the passage 60. When the passengers have boarded, the slidable seats 52 of the double-row seats 50 are moved toward the central passage 60 so that the slidable seats 52 and the fixed seats 51 have a predetermined interval.

[0059] In this case, as the moving rail 53 installed under the slidable seat 52 moves along the guide rail 54, the position of the slidable seat 52 changes, and when the slidable seat 52 is manually moved to a predetermined position, a position fixing unit is used to fix the position so that the slidable seat 52 does not move.

[0060] That is, when the slidable seat 52 moves to a suitable distance so that the hole of the moving rail 53 is aligned with the groove of the guide rail 54, the handle 55 moves so that the fastener 56 is fitted into the groove of the guide rail 54 through the hole of the moving rail 53. Therefore, the movement of the moving rail 53 is restricted so that the slidable seat 52 does not move.

[0061] On the other hand, in a state where the slidable seat 52 is automatically moved to a predetermined position, when the seat control motor 150 is stopped, the slidable seat 52 is also stopped and fixed at the moved position.

[0062] In this way, when the slidable seat 52 is moved so that the slidable seat 52 has a predetermined distance from the fixed seat 51, passengers riding in the slidable seat 52 or the fixed seat 51 will be able to travel comfortably without physical contact with each other. In particular, for passengers traveling alone without a companion, discomfort caused by physical contact with adjacent passengers will not occur, so that they can enjoy a pleasant journey. According to the preference of the passenger, the slidable seat 52 can also be used in conjunction with the fixed seat 51 without moving it, and the distance between the slidable seat 52 and the fixed seat 51 can also be adjusted to adjust the distance between the adjacent passengers.

[0063] When the bus stops and passengers want to get off, the slidable seat 52 is attached to the fixed seat 51 by manual operation or automatic control to ensure space in the passage 60, so that the passengers can move smoothly.

[0064] On the other hand, although the movement of the slidable seat 52 toward the aisle 60 can ensure the distance between the seats, when a fire or collision occurs in the bus 1, the narrowing of the aisle 60 due to the movement of the slidable seat 52 may hinder the rapid escape of passengers.

[0065] Therefore, when an accident occurs in the bus 1 or as needed, the slidable seat 52 is automatically reset to the fixed seat 51, thereby ensuring the necessity of an escape passage in an emergency.

[0066] refer to Figure 5 According to one embodiment, the bus 1 may include a flame detection sensor 70, a collision detection sensor 80, a vehicle state sensor 90, a controller 100, a speed detector 110, an acceleration detector 120, a camera 125, an input device 130, a memory 140, a seat control motor 150 and a display 160; the flame detection sensor 70 detects the occurrence of a fire in the bus 1; the collision detection sensor 80 is used to detect a collision of the bus 1; the vehicle state sensor 90 is used to detect the state of the bus 1, such as whether an accident occurs; the controller 100 is used to control the operation of each component of the bus 1; the speed detector 110 detects the driving speed of the bus 1; the acceleration detector 120 detects the acceleration of the body of the bus 1 when the bus 1 is driving; the camera 125 captures the surrounding images of the bus 1; the input device 130 receives operation-related control commands; the memory 140 stores operation-related data of the bus 1; the seat control motor 150 is used to move the slidable seat 52; the display 160 is used to display operation-related information of each component of the bus 1.

[0067] As described above, when an accident occurs in the bus 1 or when necessary, the slidable seat 52 automatically returns to the fixed seat 51 to ensure an escape route in an emergency, but if an accident occurs, unconditionally returning the slidable seat 52 may cause other risks.

[0068] In other words, even when the bus 1 has an accident, if the bus 1 continues to travel without stopping, or the bus 1 overturns or stops in a dangerous position, the slidable seat 52 may not return. For example, even when the bus 1 overturns, if the slidable seat 52 is forcibly returned to its original position, the passengers may suffer secondary injuries due to the seat being stuck.

[0069] Therefore, when an accident occurs in the bus 1 , it is necessary to consider the current driving state and driving conditions of the bus 1 to determine whether to move the slidable seat 52 .

[0070] refer to Figure 6 , the vehicle state sensor 90 can detect the occurrence of an accident of the bus 1 (1000).

[0071] When the flame detection sensor 70 detects occurrence of a fire in the bus 1 , the vehicle state sensor 90 may determine that an accident has occurred in the bus 1 , and when the collision detection sensor 80 detects a collision of the bus 1 , the vehicle state sensor 90 may determine that an accident has occurred in the bus 1 .

[0072] The flame detection sensor 70 and the collision detection sensor 80 are provided at predetermined positions of the bus 1 to detect a fire occurring on the bus 1 and a collision between the bus 1 and other objects, and transmit data to the vehicle state sensor 90 .

[0073] In addition, the vehicle state sensor 90 can determine the occurrence of a collision of the bus 1 based on a deployment signal indicating that the airbag provided in the bus 1 has been deployed. Alternatively, when it is determined that the current driving state of the bus 1 is difficult to avoid a collision with an object based on a detection result of a detection sensor (not shown) that acquires position information and speed information of another object around the bus 1 and the driving speed of the bus 1 detected by the speed detector 110, the vehicle state sensor 90 can determine that the bus 1 has collided.

[0074] When the vehicle state sensor 90 detects that an accident has occurred in the bus 1, the speed detector 110 can detect the current travel speed of the bus 1, and the controller 100 can determine whether the travel of the bus 1 has stopped according to the detection result of the speed detector 110 (1200).

[0075] That is, even when the vehicle state sensor 90 detects an accident of the bus 1 , if the travel of the bus 1 is not stopped, the controller 100 can control the seat control motor 150 so that the slidable seat 52 does not move toward the fixed seat 51 to the original position.

[0076] In addition, the camera 125 provided on the bus 1 can capture the surrounding images of the road on which the bus 1 is traveling (1300), and the acceleration detector 120 can detect the body acceleration of the bus 1 to obtain the acceleration information of the bus 1 (1400). The acceleration detector 120 can be implemented as an acceleration sensor, and the acceleration information of the bus 1 can be obtained by the acceleration sensor.

[0077] On the other hand, the controller 100 can obtain data on the slope of the road where the bus 1 is parked and data on whether the bus 1 has overturned based on the wheel acceleration information obtained by differentiating the rotation speed of the wheel of the bus 1 and the acceleration information detected by the acceleration detector 120. That is, the controller 100 can obtain the slope value of the road where the bus 1 is currently parked by the following method: receiving the rotation speed of the wheel detected at a predetermined time interval and a predetermined number of times; averaging the detected wheel rotation speed a predetermined number of times; dividing the averaged wheel rotation speed by a predetermined time to determine the wheel acceleration; and comparing the acceleration of the bus 1 detected by the acceleration detector 120 with the wheel acceleration.

[0078] Furthermore, the controller 100 may determine whether the bus 1 is overturned by using the difference between the slope value of the current position of the bus 1 and the acceleration value of the z-axis with respect to the traveling direction of the bus 1 .

[0079] The controller 100 can also determine whether the vehicle is located on a steep slope and whether the bus 1 has overturned based on the image data around the bus 1 received from the camera 125, the acceleration information of the bus 1 received from the acceleration detector 120, and the slope value information of the road corresponding to the current parking position of the bus 1.

[0080] That is, the controller 100 can determine whether the bus 1 is located on a sloped road with a predetermined slope or greater based on the image capture result of the camera 125 ( 1500 ), and can also determine whether the bus 1 is currently overturned ( 1600 ).

[0081] Based on the detection result of the driving speed of bus 1 by speed detector 110 and the detection result of the acceleration of bus 1 by acceleration detector 120, when bus 1 is parked, when the longitudinal acceleration value remains within a predetermined value for a predetermined time, controller 100 can determine that bus 1 is located on an inclined road with a slope above a predetermined slope.

[0082] Furthermore, when the bus 1 is parked, if the lateral acceleration value is greater than or equal to a predetermined value, the controller 100 may determine that the bus 1 has overturned.

[0083] When an accident of the bus 1 is detected, and the bus 1 is parked and not on a sloped road and the bus 1 is not overturned, the controller 100 may control the seat control motor 150 to move the slidable seat 52 to a predetermined original position ( 1700 ).

[0084] That is, when an accident occurs in the bus 1, if the current state of the bus 1 satisfies certain conditions, the controller 100 controls the slidable seat 52 to move toward the fixed seat 51, which can provide space for the passage 60 and ensure an escape passage in an emergency.

[0085] like Figure 3 As shown, the position where the slidable seat 52 is positioned next to the fixed seat 51 is defined as the first position. Figure 4 As shown, the position where the slidable seat 52 is positioned toward the passage 60 is defined as the second position, and the controller 100 can control the seat control motor 150 so that the slidable seat 52 is in the second position during normal travel of the bus 1, thereby providing a comfortable space between passengers.

[0086] Once an accident occurs in the bus 1 , the controller 100 controls the seat control motor 150 to move the slidable seat 52 from the second position to the first position to ensure the escape passage of the passage 60 .

[0087] As described above, the bus 1 may include an input device 130 that receives control commands related to the operation of the bus 1, and the controller 100 may control the seat control motor 150 to move the sliding seat 52 to a predetermined first position or second position based on a movement command of the sliding seat 52 received from a user.

[0088] The memory 140 may be implemented by using at least one of a nonvolatile storage element, a volatile storage element, or a storage medium, wherein the nonvolatile storage element is, for example, a cache, a read-only memory (ROM), a programmable ROM (PROM), an erasable programmable ROM (EPROM), an electrically erasable programmable ROM (EEPROM), and a flash memory, a volatile storage element is, for example, a random access memory (RAM), and a storage medium is, for example, a hard disk drive (HDD) and a CD-ROM. The implementation of the memory 90 is not limited thereto. The memory 90 may be a memory implemented by a memory chip independent of a processor associated with the above-mentioned controller 100, or the memory 90 may be implemented by a processor and a separate chip.

[0089] Furthermore, the bus 1 may include a display 160 , and the display 160 displays a control state of the slidable seat 52 according to the control of the controller 100 , and thus information on the position and movement of the slidable seat 52 may be provided to the driver.

[0090] According to the vehicle and the method for controlling the vehicle according to the exemplary embodiment of the present invention, there is the following effect: once the vehicle has an accident, the slidable seat automatically returns to its original position, thereby ensuring an escape route in the event of an emergency, thereby helping to quickly evacuate passengers and protect lives. In addition, since the slidable seat automatically returns to the original position, there is an effect that the vehicle can be easily organized after all passengers get off the vehicle.

[0091] The disclosed embodiments may be implemented in the form of a recording medium storing computer executable instructions. The instructions may be stored in the form of program code, and when executed by a processor, the operations of the disclosed embodiments may be performed by creating a program module. The recording medium may be implemented as a computer readable recording medium.

[0092] The computer-readable recording medium may include various recording media having stored therein instructions decrypted by a computer system. For example, the computer-readable recording medium may include a read-only memory (ROM), a random access memory (RAM), a magnetic tape, a magnetic disk, a flash memory, and an optical data storage device.

[0093] As is apparent from the above description, according to the proposed vehicle and method for controlling the same, once a vehicle accident occurs, the slidable seat automatically returns to its original position to ensure an escape route in the event of an emergency, thereby helping passengers to evacuate quickly and save lives. In addition, the automatic return of the slidable seat to the original position has the effect of easily organizing the vehicle after all passengers have gotten off.

[0094] Although a few embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention.
