[0001] Cross-reference to related applications
[0002] This application claims priority to Korean Patent Application No. 10-2020-0181032, filed with the Korean Intellectual Property Office on December 22, 2020, the entire contents of which are incorporated herein by reference. Technical Field
[0003] This disclosure relates to a passenger safety disembarkation aid and method thereof, and more specifically, to a device and method thereof for controlling the doors of a vehicle when a passenger is safely disembarking. Background Technology
[0004] Because parking spaces are often cramped, vehicles parked close to other cars or buildings can be difficult to open their doors. To address these issues, devices have been developed to help passengers safely exit their vehicles.
[0005] Specifically, in assisted parking, there exists a technology that uses a rear-view camera to capture images behind the vehicle to see the parking space and issues an alert when there is a risk of collision based on the distance between the vehicle and obstacles, thus assisting with parking. This technology can also set virtual lines corresponding to obstacles around the vehicle while parking. Summary of the Invention
[0006] However, while there is a technology that uses virtual lines during parking, there is no technology that uses virtual lines during passenger exit and door opening, hence the need for such a technology.
[0007] This disclosure aims to solve the aforementioned problems in the prior art while maintaining the advantages achieved by the prior art.
[0008] One aspect of this disclosure provides an apparatus for controlling the speed of a vehicle door as passengers alight to help them disembark safely. Another aspect of this disclosure provides a method thereof.
[0009] Another aspect of this disclosure provides an apparatus for controlling the speed at which a vehicle door opens when a passenger manually opens it during disembarkation to prevent damage to the door due to collisions with surrounding obstacles. Another aspect of this disclosure provides a method thereof.
[0010] Another aspect of this disclosure provides an apparatus for setting parking guide lines according to the degree of door opening, the guide lines being determined by the driver to provide convenience during the process of opening the door when passengers are alighting. Another aspect of this disclosure provides its method.
[0011] Another aspect of this disclosure provides an apparatus for allowing a driver to select different modes for setting the degree of door opening as needed, and for adjusting the degree of door opening when the driver exits the vehicle according to the mode selected by the driver.

[0013] The technical problems to be solved by this disclosure are not limited to those described above. Any other technical problems not mentioned herein should be clearly understood by those skilled in the art from the following description.
[0014] According to one aspect of this disclosure, a passenger safety exit assist device may include a sensor device that obtains information about obstacles around the vehicle and the speed at which the vehicle doors open. The passenger safety exit assist device may include a controller that sets a virtual first line along the obstacles and controls the speed at which the doors open based on at least one of the first line or the door opening speed.
[0015] In one embodiment, the controller can determine whether to control the speed at which the door opens based on whether the ratio of the distance between the vehicle and the first line to the distance between the vehicle and the second line set based on the maximum opening degree of the vehicle's door is greater than a first reference ratio.
[0016] In one embodiment, when the door opens at a speed greater than a reference speed, the controller can apply torque in the opposite direction to the door opening to control the door opening speed.
[0017] In one embodiment, the sensor device can obtain the acceleration of the door opening. When the acceleration is greater than a reference acceleration, the controller can increase torque in the opposite direction to the door opening, depending on the degree of door opening.

[0023] In one embodiment, the controller can set a third line based on the degree to which the door is opened, which corresponds to a mode selected from three modes: setting the degree of door opening based on a reference body shape, setting the degree of door opening based on the driver's frontal body shape, and setting the degree of door opening based on the driver's side body shape.
[0024] In an embodiment, the degree of door opening may include: when setting a mode for the degree of door opening based on a driver's reference body shape or frontal body shape, the calculated degree reflects the extent to which the area of the reference body shape or frontal body shape can pass through. The controller may set a third line based on the degree of door opening corresponding to the selected mode and an additional degree of door opening, the additional degree of door opening being set to prevent contact with obstacles when the door is open.
[0025] In an embodiment, when the mode for setting the degree of door opening is selected based on the driver's side profile, the controller can set the third line solely based on the degree of door opening according to the driver's side profile, without considering the distance between the vehicle and obstacles.
[0026] In an embodiment, the controller can set the selected mode by at least one of the number of times the mode selection button is pressed, the duration of the mode selection button being pressed, or the user-selected mode (USM).
[0027] In one embodiment, the controller can store the user's body shape information in a memory, and can use the body shape information stored in the memory to set the degree of door opening based on the driver's frontal body shape, and to set the degree of door opening based on the driver's side body shape.

Controlling the door opening speed may further include: when the ratio of the distance between the vehicle and the first line to the distance between the vehicle and the second line is not greater than the second reference ratio, opening the driver's seat side door at a predetermined speed according to the ratio of the distance between the vehicle and the first line to the distance between the vehicle and the second line. Controlling the door opening speed may further include: when the driver's seat side door is open toward the first line, applying torque in the direction opposite to the direction of the driver's seat side door opening while applying force in the direction of the driver's seat side door opening.
[0032] In an embodiment, the passenger safe disembarkation assistance method may further include setting a third line based on the degree of opening of the vehicle door for safe disembarkation. Controlling the door opening speed according to at least one of the first line or the door opening speed may include: automatically opening the door different from the driver's seat door toward the third line according to a signal for automatically opening the door different from the driver's seat door.

[0045] The following is for reference. Figures 1 to 7 The embodiments of this disclosure are described in detail.
[0046] Figure 1 This is a block diagram illustrating a passenger safe disembarkation assistance device according to an embodiment of the present disclosure.
[0047] See Figure 1 The passenger safety disembarkation assistance device 100 may include a sensor device 110 and a controller 120.
[0048] The passenger safe disembarkation assist device 100 can be integrated with the vehicle or implemented as a separate configuration by being installed / attached to the vehicle. Optionally, a portion of the passenger safe disembarkation assist device 100 can be integrated with the vehicle, or other portions can be implemented as a separate configuration by being installed / attached to the vehicle.
[0049] The sensor device 110 can obtain information about obstacles around the vehicle and the speed at which the vehicle doors open.
[0050] As an example, sensor device 110 can obtain the acceleration of the vehicle door opening, sense obstacles around the vehicle, and sense the driver's body shape.
[0051] As an example, sensor device 110 can be connected directly or indirectly to controller 120 via wireless or wired communication to transmit sensed information to controller 120.
[0052] The controller 120 can perform overall control, enabling each component to perform its own function normally. Such a controller 120 can be implemented in hardware, in software, or a combination thereof. The controller 120 can be implemented as a microprocessor, but is not limited to this. Furthermore, the controller 120 can perform various data processing, calculations, etc., as described below.
[0053] The controller 120 can set a virtual first line along obstacles around the vehicle and can control the speed at which the door opens based on at least one of the first line or the door opening speed. Here, the first line can include a line connecting the exterior of the surrounding obstacles, which include another vehicle, installed objects, people, and animals present around the vehicle.
[0054] As an example, controller 120 can set a second line based on the vehicle and the maximum degree of opening of the vehicle's doors, and can determine whether to control the speed of door opening based on whether the ratio of the distance between the vehicle and the first line to the distance between the vehicle and the second line is greater than a first reference ratio. Here, the second line may include the outermost line where the door is at its maximum opening when passengers are alighting from the vehicle.
[0055] As an example, controller 120 can perform various calculations using information sent from sensor device 110, and can set virtual first to third lines. Here, the third line may include the outermost line from when the door opens to the point where the door does not collide with surrounding obstacles present around the vehicle when a passenger disembarks.
[0056] As an example, controller 120 can set a first line along obstacles around the vehicle. The first line can be used to assist in the parking process.
[0057] As an example, controller 120 can set a second line based on the maximum degree to which the vehicle door is opened. The second line can be used during assisted parking.
[0058] As an example, controller 120 can set a third line based on the degree to which the vehicle door is opened for safe exit.
[0059] In detail, the controller 120 can set a third line based on the degree to which the door is opened, which is determined according to the safe exit mode input by the user. The third line can be used to assist in the parking process.
[0060] The controller 120 can apply torque in the opposite direction to the opening direction of the door, can increase or decrease the torque in the opposite direction to the opening direction of the door, and can control the door to open to a specific degree.
[0061] Figure 2 This is a block diagram illustrating a detailed configuration of a passenger safe disembarkation assistance device according to an embodiment of the present disclosure.
[0062] The sensor device 210 may include a vehicle side status and distance measuring device 211, a driver body shape measuring device 212, a door opening speed measuring device 213, a door opening acceleration measuring device 214, and a door opening load measuring device 215.
[0063] The vehicle side status and distance measuring device 211 can identify obstacles around the vehicle in the side direction and can measure the distance between the vehicle door and the obstacle.
[0064] As an example, the vehicle side status and distance measuring device 211 may include at least one of radar or camera.
[0065] The driver body measurement device 212 can measure at least one of the driver's frontal body shape and side body shape by means of a camera.
[0066] As an example, the driver body measurement device 212 may include at least one of a driver front camera or a driver side camera disposed in the vehicle.
[0067] The door opening speed measuring device 213 can obtain the speed at which the vehicle door opens.
[0068] The door opening acceleration measuring device 214 can obtain the acceleration of the vehicle when the door is opened.
[0069] The door opening load measuring device 215 can measure the force applied in the direction in which the vehicle door opens.
[0070] The controller 220 can be directly or indirectly connected to the vehicle side status and distance measuring device 211, driver body shape measuring device 212, door opening speed measuring device 213, door opening acceleration measuring device 214, door opening load measuring device 215, door opening negative torque adding device 230, alarm device 240 and input device 250 via wireless or wired communication to receive information or transmit control signals, thereby controlling the components.
[0071] The door opening negative torque applying device 230 can apply negative torque in the opposite direction to the direction in which the vehicle door is opened.
[0072] As an example, the door opening negative torque application device 230 can receive a control signal from the controller 220 and can apply negative torque in the opposite direction to the direction in which the vehicle door is opened.
[0073] The alarm device 240 may include at least one of an alarm sign display device 241 or an alarm sound generator 242.
[0074] The alarm sign display device 241 can receive alarm control signals from the controller 220 and can display or turn the alarm signs on / off via at least one of the vehicle's instrument panel or audio, video, and navigation (AVN) devices.
[0075] The alarm sound generator 242 can receive alarm control signals from the controller 220 and can output alarm sounds through at least one of the vehicle's horn, audio, and AVN.
[0076] The input device 250 may include a safe disembarkation mode input device 251 and an automatic door opening input device 252.
[0077] The safe exit mode input device 251 can receive the vehicle's safe exit mode from the user.
[0078] As an example, the safe disembarkation mode input device 251 can receive the safe disembarkation mode from the user via a mode selection button and a user-selected mode (USM).
[0079] As an example, the safe disembarkation mode input device 251 can receive the safe disembarkation mode from the user by the number of times the mode selection button is pressed or the duration of pressing the mode selection button.
[0080] Specifically, when the mode selection button of the safe exit mode input device 251 is pressed once, the controller 220 determines that a mode has been entered that sets the door opening degree based on a reference body shape. When the mode selection button is pressed twice, the controller 220 determines that a mode has been entered that sets the door opening degree based on the driver's frontal body shape. When the mode selection button is pressed three times, the controller 220 determines that a mode has been entered that sets the door opening degree based on the driver's side profile.
[0081] As an example, when the safe exit mode input device 251 receives the driver mode, the controller 220 can use the body shape information stored in the memory to set the degree to which the door is opened based on the driver's frontal body shape and the degree to which the door is opened based on the driver's side body shape.
[0082] Therefore, the controller 220 can pre-store the user's body shape information in the memory.
[0083] When the driver mode is selected, the controller 220 can directly use previously stored values without measuring body size via a camera. When the driver mode is not selected, the controller 220 can use the degree to which the door is opened based on the driver's body size.
[0084] The automatic door opening input device 252 can receive a signal from the user for automatically opening the vehicle door.
[0085] As an example, the automatic door opening input device 252 may include at least one of an automatic door opening switch or an automatic door opening handle.
[0086] As an example, the automatic door opening input device 252 can detect the operation of at least one of the automatic door opening switch or the automatic door opening handle, and can receive a signal from the user for automatic door opening.
[0087] Figure 3 This is a flowchart illustrating the process of controlling the speed of a vehicle door in manual mode in a passenger safety disembarkation assistance device according to an embodiment of the present disclosure.
[0088] refer to Figure 3 In S301, Figure 1 The passenger safety disembarkation assist device 100 can determine that the driver has selected the safe disembarkation mode.
[0089] As an example, Figure 2 The controller 220 can recognize the safe exit mode selected by the driver among multiple modes. One mode may set the door opening degree based on a reference body shape. Another mode may set the door opening degree based on the driver's frontal body shape. Yet another mode may be achieved by using... Figure 2 The safe exit mode input device 251 sets the degree of door opening based on the driver's side profile.
[0090] After confirming that the driver has selected the safe disembarkation mode, in S302, the passenger safe disembarkation assistance device 100 can generate a third line.
[0091] As an example, controller 220 can set a third line based on the degree to which the door is opened corresponding to a mode selected from multiple modes. In one example, these modes may include a mode that sets the degree of door opening based on a reference body shape, a mode that sets the degree of door opening based on the driver's frontal body shape, and a mode that sets the degree of door opening based on the driver's side body shape.
[0092] As an example, when the mode of setting the degree of door opening based on the driver's reference body shape or frontal body shape is selected, the controller 220 can set a third line based on the degree of door opening and the degree of additional door opening. The degree of door opening is calculated to allow the area reflecting the reference body shape or frontal body shape to pass through, and the degree of additional door opening is set to prevent contact with obstacles when the door is opened.
[0093] As an example, when the mode that sets the door opening degree according to the driver's side profile is selected, the controller 220 can set the third line based solely on the degree to which the door opens according to the driver's side profile, without considering the distance between the vehicle and obstacles.
[0094] After the third line is generated, in S303, the passenger safety disembarkation assistance device 100 can identify the parking space and generate the first line.
[0095] As an example, controller 220 can identify parking spaces using images of the area around the vehicle, obtained via a camera.
[0096] As an example, controller 220 can generate a virtual first line along obstacles around the parking space.
[0097] After identifying the parking space and generating the first line, in S304, the passenger safety disembarkation assistance device 100 can determine whether parking is permissible.
[0098] As an example, controller 220 can determine whether parking is permissible based on the vehicle's intended parking path and whether the first lines overlap.
[0099] When it is determined that stopping is not permissible, in S305, the passenger safety disembarkation assist device 100 can turn the alarm sign on / off and can emit an alarm sound.
[0100] As an example, controller 220 can transmit alarm signals to Figure 2 The alarm device 240 is configured to display or turn on / off an alarm sign via at least one of the instrument panel or AVN, and to output an alarm sound via at least one of the vehicle's horn, audio, or AVN.
[0101] After the alarm sign is turned on / off and the alarm sound is emitted, the passenger safety disembarkation assist device 100 can execute S303 again.
[0102] When it is determined that parking is permissible, in S306, the passenger safety disembarkation assist device 100 can determine whether the distance between the vehicle and the first line is less than 90% of the distance between the vehicle and the second line, which is set based on the maximum degree to which the vehicle door is opened.
[0103] As an example, controller 220 can set the second line based on the maximum extent to which the door is opened, and can determine whether the ratio of the distance between the vehicle and the first line to the distance between the vehicle and the second line is greater than a first reference ratio.
[0104] Here, the value 90% can be a randomized example value to give a first reference ratio, and can actually be set to another ratio.
[0105] When it is determined that the distance between the vehicle and the first line is not less than 90% of the distance between the vehicle and the second line set based on the maximum degree to which the vehicle door is opened, in S307, the passenger safety disembarkation assist device 100 can be controlled to open the door in accordance with the passenger's wishes (i.e., the door is opened by the passenger without torque being applied by the passenger safety disembarkation device).
[0106] As an example, because there is enough space to open the door, the controller 220 may fail to provide torque to the door so that the door is opened according to the passenger's wishes.
[0107] When it is determined that the distance between the vehicle and the first lane is less than 90% of the distance between the vehicle and the second lane, in S308, the passenger safety disembarkation assist device 100 can detect the load applied to the door.
[0108] As an example, controller 220 can be achieved by means of Figure 2 The door opening load measuring device 215 is used to detect the load applied to the door.
[0109] After detecting the load applied to the door, in S309, the passenger safety disembarkation assist device 100 can determine whether the speed at which the door is opened is greater than a reference speed.
[0110] As an example, controller 220 can be accessed via... Figure 2 The door opening speed measuring device 213 obtains the speed at which the door is opened, and can compare the obtained speed with a reference speed stored in the memory to determine whether the speed at which the door is opened is greater than the reference speed.
[0111] When it is determined that the speed at which the door is opened is not greater than the reference speed, in S312, the passenger safety disembarkation assist device 100 can control the door to open toward the first line.
[0112] As an example, when it is determined that there is no damage to the vehicle or surrounding obstacles as the passenger slowly opens the door, the controller 220 can control the door to open to the first line without applying torque to the door.
[0113] When it is determined that the speed at which the door opens is greater than the reference speed, in S310, the passenger safety disembarkation assist device 100 can apply a negative torque in the direction in which the door opens.
[0114] As an example, when the door opens at a speed greater than a reference speed, the controller 220 can apply torque in the opposite direction to the door opening to control the door opening speed.
[0115] As an example, when the door opens at a speed greater than a reference speed, the controller 220 can transmit a control signal to... Figure 2 The door opening negative torque amplification device 230 shown can distribute torque in the opposite direction to the door opening direction.
[0116] After distributing negative torque in the door opening direction, in S311, the passenger safety disembarkation assist device 100 can be controlled to make the door open slowly.
[0117] As an example, controller 220 can distribute torque in the direction opposite to the direction the door opens to control the door to open at a reference speed.
[0118] After the door is opened slowly, in S312, the passenger safety disembarkation assist device 100 can be controlled to open the door toward the first line.
[0119] Figure 4 This is a flowchart illustrating the process of controlling the speed of the vehicle door in manual mode according to the acceleration of the door in a passenger safety disembarkation assistance device according to an embodiment of the present disclosure.
[0120] See Figure 4 In S401, Figure 1 The passenger safety disembarkation assist device 100 shown can determine whether the acceleration of opening the door is greater than a reference acceleration.
[0121] As an example, Figure 2 The controller 220 shown can be used by means of Figure 2 The door opening acceleration measuring device 214 obtains the acceleration of opening the car door. It can then compare the obtained acceleration with a reference acceleration stored in a memory to determine whether the door opening acceleration is greater than the reference acceleration.
[0122] When it is determined that the acceleration for opening the door is not greater than the reference acceleration, in S405, the passenger safety disembarkation assist device 100 can be controlled to open the door toward the first line.
[0123] As an example, when the acceleration of the door opening is not greater than the reference acceleration, the controller 220 can control the door to open towards the first line without increasing the torque applied to the door.
[0124] When it is determined that the acceleration of the door opening is greater than the reference acceleration, in S402, the passenger safety disembarkation assist device 100 can increase the negative torque according to the degree of door opening.
[0125] As an example, controller 220 can transmit control signals to Figure 2 The door opening negative torque amplification device 230 shown increases the negative torque according to the degree to which the door is opened.
[0126] After increasing the negative torque according to the degree of door opening, in S403, the passenger safety exit assist device 100 can determine whether the door opening acceleration is not greater than the reference acceleration.
[0127] As an example, the controller 220 can obtain the acceleration of opening the door by means of the door opening acceleration measuring device 214, and can compare the obtained acceleration with the reference acceleration stored in the memory in the same way as in S401 to determine whether the acceleration of opening the door is greater than the reference acceleration.
[0128] When it is determined that the acceleration for opening the door is greater than the reference acceleration, the passenger safety disembarkation assist device 100 can execute S402 again.
[0129] When it is determined that the acceleration of opening the door is not greater than the reference acceleration, in S404, the passenger safety disembarkation assist device 100 can fix the negative torque.
[0130] After the fixed negative torque is applied, in S405, the passenger safety disembarkation assist device 100 can be controlled to open the door toward the first line.
[0131] Figure 5 This is a flowchart illustrating the process of controlling the speed of a vehicle door when opening the driver's seat side door in automatic mode in a passenger safety disembarkation assistance device according to an embodiment of the present disclosure.
[0132] See Figure 5 In S501, Figure 1 The passenger safety disembarkation assist device 100 shown can determine that the driver has selected the safe disembarkation mode.
[0133] After confirming that the driver has selected the safe disembarkation mode, in S502, the passenger safe disembarkation assistance device 100 can generate a third line.
[0134] After the third line is generated, in S503, the passenger safety disembarkation assistance device 100 can identify the parking space and generate the first line.
[0135] After identifying the parking space and generating the first line, in S504, the passenger safety disembarkation assistance device 100 can determine whether parking is possible.
[0136] When it is determined that stopping is not possible, in S505, the passenger safety disembarkation assist device 100 can turn the alarm sign on / off and can emit an alarm sound.
[0137] After the alarm sign is turned on / off and the alarm sound is emitted, the passenger safety disembarkation assist device 100 can execute S503 again.
[0138] Because S501 to S505 and Figure 3 S301 to S305 are the same, and their detailed descriptions are omitted.
[0139] When it is determined that parking is permissible, in S506, the passenger safety disembarkation assist device 100 can determine whether the distance between the vehicle and the first line is less than 90% of the distance between the vehicle and the second line set based on the maximum degree of opening of the vehicle door.
[0140] As an example, Figure 2 The controller 220 can determine whether the ratio of the distance between the vehicle and the first line to the distance between the vehicle and the second line set based on the maximum opening degree of the door is greater than a second reference ratio.
[0141] Here, the value 90% can be a value that is randomly set to give an example of the second reference ratio, and can be set to the same value as the first reference ratio, or it can be set to a value different from the first reference ratio.
[0142] When it is determined that the distance between the vehicle and the first line is not less than 90% of the distance between the vehicle and the second line, in S507, the passenger safety exit assist device 100 can determine that the door opening switch or automatic opening handle on the driver's seat side has been operated.
[0143] As an example, controller 220 can be accessed via... Figure 2 The automatic door opening input device 252 determines whether the driver's seat door opening switch or the automatic door opening handle is operated.
[0144] After determining that the driver's seat door switch or automatic opening handle has been activated, in S508, the passenger safety exit assist device 100 can be controlled to open the driver's seat door at a specific speed.
[0145] As an example, controller 220 can automatically open the driver's seat door toward the first line based on a signal for automatically opening the driver's seat door.
[0146] As an example, when it is determined that the distance between the vehicle and the first line is not less than 90% of the distance between the vehicle and the second line, and when it is determined that the driver's seat door opening switch or automatic opening handle is operated, the passenger safety exit assist device 100 can be controlled to open the driver's seat door at a specific speed pre-stored in the memory.
[0147] When it is determined that the distance between the vehicle and the first line is less than 90% of the distance between the vehicle and the second line, in S509, the passenger safety exit assist device 100 can determine that the driver's seat door opening switch or automatic opening handle has been operated.
[0148] As an example, controller 220 can determine that the driver's seat door opening switch or automatic door handle is operated via automatic door opening input device 252 in the same manner as in S507.
[0149] After determining that the driver's seat door opening switch or automatic opening handle has been operated, in S510, the passenger safety exit assist device 100 can be controlled to slowly open the door toward the first line.
[0150] As an example, controller 220 can control the vehicle to open the driver's seat door toward the first line at a predetermined speed based on the ratio of the distance between the vehicle and the first line to the distance between the vehicle and the second line.
[0151] As an example, compared to less than or equal to 80%, when the ratio of the distance between the vehicle and the first line to the distance between the vehicle and the second line is less than or equal to 60%, the controller 220 can control the driver's seat door to open towards the first line at a lower predetermined speed.
[0152] After controlling the door to open slowly toward the first line, in S511, the passenger safety disembarkation assist device 100 can determine whether additional load is detected in the direction the door is opening.
[0153] As an example, controller 220 can be achieved by means of Figure 2 The door opening load measuring device 215 determines whether additional load is detected in the direction the door is opened.
[0154] When it is determined that additional load is detected in the direction of door opening, in S512, the passenger safety disembarkation assist device 100 can apply negative torque in the direction of door opening to prevent the door from opening suddenly.
[0155] As an example, controller 220 can transmit control signals to Figure 2The door opening negative torque amplification device 230 shown can distribute torque in the opposite direction to the door opening direction of the driver's seat, so that the door will not open suddenly.
[0156] Figure 6 This is a flowchart illustrating the process of controlling the door speed when opening a door different from the door on the driver's seat side (i.e., a different door) in automatic mode in a passenger safety disembarkation assistance device according to an embodiment of the present disclosure.
[0157] See Figure 6 In S601, Figure 1 The passenger safety disembarkation assist device 100 shown can determine that the driver has selected the safe disembarkation mode.
[0158] After confirming that the driver has selected the safe disembarkation mode, in S602, the passenger safe disembarkation assistance device 100 can generate a third line.
[0159] After the third line is generated, in S603, the passenger safety disembarkation assistance device 100 can identify the parking space and generate the first line.
[0160] After identifying the parking space and generating the first line, in S604, the passenger safety disembarkation assistance device 100 can determine whether parking is possible.
[0161] When it is determined that stopping is not possible, in S605, the passenger safety disembarkation assist device 100 can turn the alarm sign on / off and can emit an alarm sound.
[0162] After the alarm sign is turned on / off and the alarm sound is emitted, the passenger safety disembarkation assist device 100 can execute S603 again.
[0163] When it is determined that parking is permissible, in S606, the passenger safety disembarkation assist device 100 can determine whether the distance between the vehicle and the first line is less than 90% of the distance between the vehicle and the second line.
[0164] Because S601 to S606 and Figure 5 S501 to S506 are the same, and their detailed descriptions are omitted.
[0165] When it is determined that the distance between the vehicle and the first line is not less than 90% of the distance between the vehicle and the second line, in S607, the passenger safety exit assist device 100 can determine that the door opening switch or automatic opening handle of the door (i.e., the different door) that is different from the driver's seat door can be operated.
[0166] As an example, controller 220 can be accessed via... Figure 2The automatic door opening input device 252 determines that the door opening switch or automatic opening handle of a door different from the driver's seat door is operated.
[0167] After determining that the door opening switch or automatic opening handle of the door different from the driver's seat door has been operated, in S608, the passenger safety exit assist device 100 can be controlled to open the door different from the driver's seat door at a specific speed.
[0168] As an example, controller 220 can automatically open a door that is different from the driver's seat door to a third line based on a signal for automatically opening a door that is different from the driver's seat door.
[0169] When it is determined that the distance between the vehicle and the first line is not less than 90% of the distance between the vehicle and the second line, and when it is determined that the door opening switch or automatic opening handle of a door different from the driver's seat door has been operated, the controller 220 can control the door different from the driver's seat door to open at a specific speed pre-stored in the memory.
[0170] When it is determined that the distance between the vehicle and the first line is less than 90% of the distance between the vehicle and the second line, in S609, the passenger safety exit assist device 100 can determine that the door opening switch or automatic opening handle of the door different from the driver's seat door can be operated.
[0171] As an example, controller 220 can determine whether to operate the door opening switch or automatically open the handle of a door different from the driver's seat door via automatic door opening input device 252 in the same manner as in S607.
[0172] After it is determined that the door opening switch or automatic opening handle of the door different from the driver's seat door has been operated, in S610, the passenger safety disembarkation assist device 100 can be controlled to slowly open the different door toward the third line.
[0173] As an example, controller 220 can control the vehicle based on the ratio of the distance between the vehicle and the first line to the distance between the vehicle and the second line, so that the door, which is different from the driver's seat door, opens toward the first line at a predetermined speed.
[0174] After controlling the different doors to open slowly toward the third line, in S611, the passenger safety disembarkation assist device 100 can determine whether additional load is detected in the different door opening directions.
[0175] As an example, controller 220 can be achieved by means of Figure 2 The door opening load measuring device 215 determines whether additional load is detected in different door opening directions.
[0176] When it is determined that additional load is detected in the direction of door opening, in S612, the passenger safety disembarkation assist device 100 can apply negative torque in different directions of door opening.
[0177] As an example, controller 220 can transmit control signals to Figure 1 The door opening negative torque amplification device 230 is shown. It can distribute torque in the opposite direction to the opening direction of the door to the driver's seat door, preventing the door from opening suddenly.
[0178] After distributing negative torque in different door opening directions, in S613, the passenger safety disembarkation assist device 100 can be controlled to make the different doors open towards the first line again.
[0179] As an example, controller 220 can be controlled to reflect the passenger's wishes, causing a door that is separate from the driver's seat door to open additionally to the first line.

Figure 2 The sensor device 210 performs the operation using the vehicle side status and distance measuring device 211 and the door opening speed measuring device 213.
[0183] Setting a virtual first line along the obstacle (S720) can be performed during assisted parking, or can be done by... Figure 2 The controller 220 uses images for execution, which are acquired by means of sensor device 210 through a separate process.
[0184] The door opening speed is controlled based on at least one of the first line or the door opening speed (S730). This can be achieved by means of controller 220 and... Figure 2 The negative torque device 230 in the middle is used to perform the opening.
[0185] As an example, controlling the door opening speed based on at least one of the first line or the door opening speed (S730) may include determining whether to control the door opening speed based on the ratio of the distance between the vehicle and the first line to the distance between the vehicle and the second line set based on the maximum degree of opening of the vehicle door.

[0187] As an example, controlling the door opening speed (S730) based on at least one of the first line or the door opening speed may include: when the ratio of the distance between the vehicle and the first line to the distance between the vehicle and the second line set based on the maximum opening degree of the vehicle door is greater than a second reference ratio, opening the driver's seat door at a specific speed based on a signal for automatically opening the driver's seat door. Controlling the door opening speed (S730) may also include: when the ratio of the distance between the vehicle and the first line to the distance between the vehicle and the second line is not greater than the second reference ratio, opening the driver's seat door at a predetermined speed based on the ratio of the distance between the vehicle and the first line and the distance between the vehicle and the second line, using a signal for automatically opening the driver's seat door. Controlling the door opening speed (S730) may also include, while the driver's seat door is open toward the first line, applying torque in the direction opposite to the opening direction of the driver's seat door when a force is applied in the direction of the driver's seat door opening.
[0188] As an example, controlling the door opening speed (S730) based on at least one of the first line or the door opening speed may include: automatically opening the door different from the driver's seat door to the third line according to a signal for automatically opening the door different from the driver's seat door. Controlling the door opening speed (S730) may also include: when the door different from the driver's seat door is opened to the third line, when a force is applied in the direction of opening of the door different from the driver's seat door, applying torque in the opposite direction of opening of the door different from the driver's seat door to open the door different from the driver's seat door to the first line.
