  An example in which the entrance / exit opening / closing device 10 as an opening / closing device for a vehicle entrance opening / closing device according to a first embodiment of the present invention is applied to an automobile S will be described with reference to FIGS. 1 to 5. In the figure, the arrow FR indicates the front direction of the vehicle body, and the arrow OUT indicates the outside in the vehicle width direction. When the description is made using the left and right directions, the left and right directions when viewed in the direction of the arrow FR are shown.

  FIG. 1 shows a schematic plan view of the schematic configuration of the automobile S, and FIG. 3 shows the automobile S in a perspective view. As shown in these drawings, the automobile S includes a vehicle body 12, and a vehicle compartment 14 is provided in the vehicle body 12 for a person (hereinafter referred to as an occupant before or after boarding) to get on. It has been. In addition, the vehicle body 12 is provided with an opening 16 for getting on and off for an occupant to get on and off the passenger compartment 14.

  The entrance / exit 16 is disposed between the front wheel 18 and the rear wheel 20 in the first embodiment. As shown in FIG. 3, the entrance opening 16 has a front opening 16 </ b> A for mainly accessing the front seat (driver's seat and front passenger seat) 22 in the passenger compartment 14, and in the passenger compartment 14. A rear opening 16B mainly for accessing the rear seat 24 is configured to communicate with each other over the entire height along the vertical direction of the vehicle body. That is, the automobile S includes a vehicle body structure that does not include a center pillar that partitions the front opening 16A and the rear opening 16B, and functions between the front opening 16A and the rear opening 16B. There is no clear boundary above.

  As shown in FIG. 1, the entrance / exit openings 16 are respectively provided on the left and right sides of the automobile S, and are opened or closed manually or electrically by the entrance / exit opening / closing device 10. In this embodiment, the left and right entrance / exit openings 16 and the entrance / exit opening / closing device 10 are basically symmetrical, and therefore, the left / right entrance / exit openings 16 and the entrance / exit opening / closing device 10 will be described without particular distinction. I decided to.

  The entrance / exit opening / closing device 10 includes a hinge door 26 that opens and closes the front opening 16A of the entrance 16 and a slide door 28 that opens and closes the rear opening 16B of the entrance 16. In other words, the portion of the entrance / exit 16 where the hinge door 26 opens and closes is the front opening 16A, and the portion where the slide door 28 opens and closes is the rear opening 16B. As shown in FIG. 1, the hinge door 26 is pivotally supported with respect to the vehicle body 12 by a hinge shaft 30 as a support shaft provided at a front edge portion of the opening 16 for getting on and off in the vehicle body 12.

  As a result, the hinge door 26 is moved from the closed position as shown in the right seat side (upper side of the paper) in FIG. 1 to close the front opening 16A and from the closed position as shown in the left side seat (lower side of the paper) in FIG. Around the hinge shaft 30, it is configured to be able to take an open position that rotates about 90 ° in the direction of the arrow A and enables getting on and off (access to the front seat 22) through the front opening 16 </ b> A. Further, the hinge door 26 returns from the open position to the closed position by rotating around the hinge shaft 30 in the direction of the arrow B opposite to the arrow A. In the first embodiment, the hinge door 26 is configured to rotate between a closed position and an open position by an occupant manually opening and closing.

  The slide door 28 is configured by supporting a roller guided by a guide rail provided along the front-rear direction on the vehicle body 12 of the automobile S via a bracket (both not shown), and the roller is a guide rail. It slides in the front-rear direction while being guided by. The front end of the guide rail is inclined or curved inward in the vehicle width direction.

  As a result, the slide door 28 is closed as shown in the right seat side (upper side of the paper) in FIG. 1 and in the closed position where the rear opening 16B is closed, and in the left side seat (lower side of the paper) in FIG. It is configured to be able to take an open position that allows the passenger to get on and off (access to the rear seat 24) through the rear opening 16B by sliding from the position to the rear side. The sliding door 28 is configured to slide backward while moving slightly outward in the vehicle width direction by the guide rail whose front end is inclined or curved as described above at the initial stage of the operation of moving from the closed position to the open position. The slide door 28 returns from the open position to the closed position by an operation opposite to the operation of moving from the closed position to the open position. As the sliding mechanism of the sliding door 28, other mechanisms such as providing a guide rail on the sliding door 28 side may be employed.

  The sliding door 28 is configured to be capable of opening / closing the rear opening 16B by the electric opening / closing device 32 (see FIG. 1) in addition to the opening / closing operation of the rear opening 16B by manual operation of the passenger. The electric opening / closing device 32 is configured to move the slide door 28 between the closed position and the open position by operating the hand switch of the occupant, and to stop and hold at the intermediate position. The electric opening / closing device 32 has, for example, a configuration in which a roller driven by a motor is pressed against the inner surface of the slide door 28 to transmit power to the slide door 28, and each cable for opening and closing has one end attached to the slide door 28. Various configurations, such as a configuration in which the slide door 28 is driven by winding each of these with a drum driven by a motor, can be employed.

  As shown in FIG. 1, the entrance / exit opening / closing device 10 includes a door ECU 34 as a control device that automatically operates the electric opening / closing device 32 in a predetermined case. The door ECU 34 is electrically connected to the electric opening / closing device 32. Further, the door ECU 34 is electrically connected to a courtesy switch 36 as a hinge door opening detector that detects opening / closing operation of the hinge door 26 and an obstacle sensor 38 as an obstacle detector provided in the hinge door 26. In addition, about each apparatus electrically connected to door ECU34 including the front seat drive apparatus 40 mentioned later, it shall illustrate in FIG. 1 about the thing for right seats.

  The courtesy switch 36 is a signal (ON / OFF) according to the presence / absence of an opening operation (door lever operation) of the hinge door 26, that is, the presence / absence of an occupant's intention to open the front opening 16A, in order to light an interior lamp or the like when operating the hinge door 26. This is a switch that outputs an OFF signal. A signal output by the courtesy switch 36 when the hinge door 26 is opened is referred to as an opening signal.

  As shown in FIG. 3, the obstacle sensor 38 is attached to the rear end of the outer surface of the hinge door 26. This obstacle sensor 38 determines whether or not an obstacle exists within a predetermined range on the outer side in the vehicle width direction of the hinge door 26 when the hinge door 26 is located at the closed position (an object existing on the open position side). A signal is output (changes the output timing of the signal) according to whether or not it is an obstacle. In this embodiment, the obstacle sensor 38 is an ultrasonic sensor, transmits an ultrasonic wave toward the open position side of the hinge door 26, and outputs a signal according to whether or not the reflected wave of the ultrasonic wave is detected to the door ECU 34. To output.

  When the time T from when the obstacle sensor 38 transmits an ultrasonic wave until the reflected wave is detected is equal to or greater than a preset threshold value T0, the door ECU 34 determines that there is no obstacle on the opening position side of the hinge door 26. When the time T is less than the threshold value T0, it is determined that an obstacle exists on the opening position side of the hinge door 26. This threshold value is set so as to detect whether or not an obstacle exists in a range where the hinge door 26 interferes when it tries to rotate to the open position side so that the passenger can smoothly get on and off from the front opening 16A. ing. In other words, on the basis of the output of the obstacle sensor 38, the door ECU 34 has a pivotable amount to the opening position side of the hinge door 26 at a predetermined angle that allows a passenger to smoothly get on and off from the front opening 16A. It is configured to determine whether or not there is. More specifically, in this embodiment, it is detected whether or not there is an obstacle that interferes with the rotation trajectory in which the hinge door 26 rotates to the open position (the rotation limit in the direction of arrow A). Yes.

  When the time T is less than the threshold value T0, the door ECU 34 operates the electric opening / closing device 32 to move the slide door 28 rearward by a predetermined amount M1 (for example, about 200 mm) as shown in FIG. It is supposed to let you. Accordingly, when the front opening 16A is not sufficiently opened due to the presence of the obstacle H, the rear opening 16B communicating with the rear side of the front opening 16A is opened by a predetermined amount, and the entrance / exit 16 The entire opening width is ensured. The obstacle sensor 38 may output a signal corresponding to the magnitude of the time T with respect to the threshold value T0, and a predetermined detection range (for example, a sound wave or light having a predetermined intensity emitted from the sensor is reflected). It may be a switch that outputs an ON / OFF signal depending on whether or not an obstacle exists within a limit distance (return to the sensor).

  The door ECU 34 receives various vehicle information from various sensors provided in the automobile S, other ECUs, and the like, and determines whether the automobile S is stopped based on these information. It has become. Specifically, for example, when the automobile S is configured to include an automatic transmission, when a signal corresponding to the shift lever being in the parking range is input, or the shift lever is in the neutral range. When both the corresponding signal and the signal corresponding to the parking brake being locked are input, it is determined that the vehicle S is stopped. Further, for example, when the vehicle S is configured to include a manual transmission, when the signal corresponding to the parking brake being locked is input or when the signal corresponding to the engine stop is input, the vehicle It is determined that S is stopped.

  The door ECU 34 is configured not to operate the obstacle sensor 38 or to operate the electric opening / closing device regardless of the input signal from the obstacle sensor 38 when the automobile S is not stopped. . That is, when the door ECU 34 determines that the automobile S is traveling, the door ECU 34 does not automatically move the slide door 28 to the open position side.

  Furthermore, the entrance / exit opening / closing device 10 includes a front seat drive device 40 as a seat drive device. The front seat drive device 40 includes, for example, a motor and a motion conversion mechanism that converts the rotational force of the motor into a moving force along the front-rear direction of the front seat 22. The front seat drive device 40 is electrically connected to and controlled by the door ECU 34. Specifically, the door ECU 34 operates the front seat drive device 40 as shown in FIG. 2 at the same time as driving the electric opening / closing device 32 to slide the slide door 28 rearward or with a slight time difference. Thus, the front seat 22 is moved backward by a predetermined amount M2. Therefore, in this embodiment, the front seat 18 corresponds to the seat in the present invention.

  In the entrance / exit opening / closing device 10 described above, the door ECU 34 controls the left and right sliding doors 28 (electrical opening / closing device 32) based on outputs from the courtesy switch 36 and the obstacle sensor 38 respectively corresponding to the left and right hinge doors 26. The left and right front seats 22 (front seat drive device 40) are independently controlled.

  Next, the operation of the first embodiment will be described with reference to the flowchart shown in FIG.

  In the automobile S to which the entrance / exit opening / closing device 10 having the above configuration is applied, the door ECU 34 determines whether or not the automobile S is surely stopped based on various vehicle information in step S10. When it is determined that the car S has not stopped, the process returns to step S10 and is repeated until the car S stops.

  If it is determined in step S10 that the vehicle has stopped reliably, the process proceeds to step S12. In step S12, based on the output of the obstacle sensor 38, it is determined whether there is an obstacle on the open position side of the hinge door 26 on the outer side in the vehicle width direction. If it is determined that no obstacle exists, the process returns to step S10. When the hinge door 26 is opened during the period in which the steps S10 and S12 are repeated, there is no obstacle, so the occupant can rotate the hinge door 26 in the direction of arrow A to the open position. When the hinge door 26 is rotated to the open position, the front opening 16A of the passenger opening 16 is opened widely, and the front seat occupant can get on and off smoothly.

  On the other hand, if it is determined in step S12 that an obstacle exists, the process proceeds to step S14. In step S14, it is determined whether or not the hinge door 26 is opened based on an input signal from the courtesy switch 36. If no opening signal is input from the courtesy switch 36, it is determined that the hinge door 26 has not been opened, and the process returns to step S10. If an open signal is input from the courtesy switch 36, that is, if it is determined that the hinge door 26 has been opened, the process proceeds to step S16. In step S16, by operating the electric opening / closing device 32, the slide door 28 is moved rearward by a predetermined amount M1. Next, the process proceeds to step S18. In step S18, by operating the front seat drive device 40, the front seat 22 is moved backward by a predetermined amount M2. Steps S16 and S18 may be performed in the reverse order or may be executed simultaneously.

  That is, the slide door 28 and the front seat 22 shown in FIG. 3 are automatically moved backward by executing steps S16 and S18 from the state shown in FIG. 4 in which the hinge door 26 is opened in step S14. It will be in the state. Thereby, when the other vehicle parked on the side of the automobile S, a wall located on the side of the automobile S, or the like exists as an obstacle H, the front door is opened by turning the hinge door 26 to the arrow A side. Although 16A cannot be opened widely, a part (or all) of the rear opening 16B communicating with the front opening 16A can be used to secure an opening width for passenger getting on and off.

  Therefore, the occupant seated on the front seat 22 can get off via the wide opening 16 for getting on and off, and the occupant who gets on and sits on the front seat 22 has wide opening. It is possible to board via the opening 16 for getting on and off. Moreover, since the front seat 22 has moved to the rear opening 16B side, as shown in FIG. 2, the width Wa of the foot space on the road surface when getting on and off does not include the entrance opening / closing device 10. It is significantly enlarged compared to the width Wb of the foot space. For this reason, the occupant can get on and off the front seat in the passenger compartment 14 with a comfortable posture without twisting his / her waist.

  As described above, in the entrance opening / closing device 10 according to the first embodiment, by operating the hinge door 26, the opening 16 for getting on and off the vehicle body 12 can be opened so that a front passenger can get on and off, and the front door The boarding / exiting ability of the seat occupants is good.

  Next, a gate opening / closing device 50 according to a second embodiment of the present invention will be described with reference to FIGS. In addition, when it has the fundamentally the same component and part as the said 1st Embodiment, the same code | symbol as 1st Embodiment or the same may be attached | subjected and illustration and description may be abbreviate | omitted.

  FIG. 6 shows a schematic plan view of an automobile S to which the entrance opening / closing device 50 is applied, corresponding to FIG. As shown in this figure, the entrance / exit opening / closing device 50 includes a door ECU 52 instead of the door ECU 34, and an obstacle sensor 54 as a rotation amount detector instead of the obstacle sensor 38. It differs from the gate opening / closing device 10 according to the embodiment.

  The obstacle sensor 54 is basically different from the obstacle sensor 38 that detects the presence or absence of an obstacle in that it outputs an analog signal corresponding to the distance from the obstacle (for the purpose of distance detection). In this embodiment, the obstacle sensor 54 is an ultrasonic or optical distance sensor, for example, and when there is an object that reflects the transmitted ultrasonic wave or light within the detection range, this reflected wave is present. A signal corresponding to the time until receiving, that is, the distance to the object is output. When no reflected wave is received, a 0 signal is output. The state in which the obstacle sensor 54 outputs a 0 signal corresponds to a state in which no obstacle exists within the range in which the hinge door 26 is rotated from the closed position to the open position. In other words, when the obstacle sensor 54 outputs a signal corresponding to the distance to the object, there is an obstacle within the range in which the hinge door 26 is rotated from the closed position to the open position. The signal corresponds to the distance between the rear end of the hinge door 26 (obstacle sensor 54) and the obstacle. This signal is called a distance signal.

  As the obstacle sensor 54, a sensor that outputs a signal corresponding to the detection of the reflected wave is used similarly to the obstacle sensor 38, and the obstacle is based on the time from the ultrasonic wave transmission to the reception of the reflected wave on the door ECU 52 side. The presence / absence of an object and the distance to the obstacle may be detected and calculated. Conversely, a sensor that outputs a signal corresponding to the distance, such as the obstacle sensor 54, can be used as the obstacle sensor 38.

  The door ECU 52 calculates a required movement amount L to the rear side of the sliding door 28 when there is an obstacle based on a distance signal input from the obstacle sensor 54. Specifically, as shown in FIG. 7, the door ECU 52 stores an opening width L0 along the front-rear direction sufficient for the passenger to get on and off smoothly as a set value. Further, the door ECU 52 calculates the opening width L1 of the front opening 16A when the hinge door 26 is rotated in the direction of arrow A within a range not interfering with an obstacle. Thereby, the required moving amount L to the rear side of the slide door 28 when there is an obstacle can be calculated as L = L0−L1. In this embodiment, the opening width L0 is set to substantially coincide with the opening width L1 when the hinge door 26 is located at the open position.

The opening width L1 of the front opening 16A is a distance Lh along the vehicle width direction between the rear end of the hinge door 26 and the obstacle H obtained from a distance signal input from the obstacle sensor 54, and a hinge door stored in advance. It can be calculated as L1 = Ld− (Ld ² −Lh ² ) ^1/2 from the length 26 (turning radius) Ld. Needless to say, the required movement amount L to the rear side of the slide door 28 may be directly calculated as L = L0−Ld + (Ld ² −Lh ² ) ^1/2 . In the second embodiment, the door ECU 52 is configured to move the slide door 28 to the rear side by the required movement amount L or more. Further, the door ECU 52 changes the amount of rearward movement of the front seat 22 in accordance with the required amount of movement L. In the second embodiment, the front seat 22 is moved rearward by the actual movement amount Ls (≧ L) of the slide door 28.

  Other configurations of the entrance / exit opening / closing device 50 are the same as those of the entrance / exit opening / closing device 10.

  Next, the operation of the second embodiment will be described with reference to the flowchart shown in FIG.

  In the automobile S to which the entrance / exit opening / closing device 50 having the above-described configuration is applied, the door ECU 52 determines whether or not the automobile S is surely stopped based on various vehicle information in step S20. When it is determined that the car S is not stopped, the process returns to step S20 and is repeated until the car S stops.

  If it is determined in step S20 that the vehicle has stopped reliably, the process proceeds to step S22. In step S22, it is determined whether or not a 0 signal is input from the obstacle sensor 54, that is, whether or not there is an obstacle on the open position side of the hinge door 26 on the outer side in the vehicle width direction. If it is determined that no obstacle exists, the process returns to step S20. When the hinge door 26 is opened during the period in which the steps S20 and S22 are repeated, there is no obstacle, so the occupant can turn the hinge door 26 in the direction of arrow A to the open position. When the hinge door 26 is rotated to the open position, the front opening 16A of the passenger opening 16 is opened widely, and the front seat occupant can get on and off smoothly.

On the other hand, if it is determined in step S22 that an obstacle exists, the process proceeds to step S24. In step S24, a distance Lh along the vehicle width direction between the rear end of the hinge door 26 and the obstacle H is obtained based on the distance signal input from the obstacle sensor 54. Then, the process proceeds to step S26, and in step S26, the required movement amount L (= L0−L1 = L0−Ld + (Ld ² −Lh ² ) ^1/2 ) of the slide door 28 is calculated using the distance Lh. When the necessary movement amount L is calculated, the process proceeds to step S28.

  In step S28, it is determined whether or not the hinge door 26 is opened based on an input signal from the courtesy switch 36. If no opening signal is input from the courtesy switch, it is determined that the hinge door 26 has not been opened, and the process returns to step S20. If an open signal is input from the courtesy switch, that is, if it is determined that the hinge door 26 has been opened, the process proceeds to step S30. In step S30, by operating the electric opening / closing device 32, the slide door 28 is moved to the rear side by a distance Ls that is equal to or greater than the necessary movement amount L. Next, the process proceeds to step S32. In step S32, by operating the front seat drive device 40, the front seat 22 is moved rearward by a distance Ls. Steps S30 and S32 may be executed in reverse order or simultaneously.

  That is, the slide door 28 and the front seat 22 are automatically moved backward by executing steps S30 and S32 from the state in which the hinge door 26 is opened in step S28 (a state corresponding to FIG. 4). A state (a state corresponding to FIG. 3) is obtained. Thereby, when the other vehicle parked on the side of the automobile S, a wall located on the side of the automobile S, or the like exists as an obstacle H, the front door is opened by turning the hinge door 26 to the arrow A side. Although 16A cannot be opened widely, a part (or all) of the rear opening 16B communicating with the front opening 16A can be used to secure an opening width for passenger getting on and off.

  Therefore, the occupant seated on the front seat 22 can get off via the wide opening 16 for getting on and off, and the occupant who gets on and sits on the front seat 22 has wide open. It is possible to board via the opening 16 for getting on and off. Then, the door ECU 52 calculates the necessary moving amount L of the sliding door 28 according to the distance Lh between the hinge door 26 and the obstacle H, and based on this result, the actual moving amount Ls of the sliding door 28 is set to Ls ≧ L. Even when there is an obstacle H on the rotation trajectory of the hinge door 26 from the closed position to the open position, the entrance opening 16 has an opening having an opening width L0 or more sufficient for the passenger to get on and off smoothly. The width is secured. That is, the front seat occupant can smoothly get on and off regardless of the presence of the obstacle H and the distance from the hinge door 26.

  In addition, since the front seat 22 has moved to the rear opening 16B side, although not shown in FIG. 7, the width Wa of the foot space on the road surface at the time of getting on and off is similar to that shown in FIG. However, it is remarkably enlarged as compared with the width Wb of the foot space of the configuration without the entrance opening / closing device 10. For this reason, the occupant can get on and off the front seat in the passenger compartment 14 with a comfortable posture without twisting his / her waist.

  As described above, in the entrance opening / closing device 50 according to the second embodiment, by operating the hinge door 26, the entrance 16 for the entrance / exit of the vehicle body 12 can be opened so that the front passenger can get on / off, and the front door The boarding / exiting ability of the seat occupants is good.

  Next, an entrance opening / closing device 60 according to a third embodiment of the present invention will be described with reference to FIGS. 9 and 10. In addition, in the case of having basically the same components / parts as those in the first or second embodiment, the same reference numerals as those in the first or second embodiment are attached, and the illustration and description are omitted. is there.

  FIG. 9 shows a schematic plan view of the automobile S to which the doorway opening / closing device 60 is applied, corresponding to FIG. 6. As shown in this figure, the entrance / exit opening / closing device 60 includes a door ECU 62 instead of the door ECU 52, and includes a front seat detection sensor 64 instead of the front seat driving device 40. It differs from the gate opening / closing apparatus 50 which concerns on.

  The front seat detection sensor 64 is fixed to a floor or the like that forms the bottom of the passenger compartment, and outputs an ON signal when the front seat 22 is present at a boarding / alighting position within a predetermined range. In the third embodiment, the boarding / alighting position is a position sufficiently separated (for example, about 200 mm) rearward from the normal use position (driving position or the like) of the front seat 22.

  The door ECU 62 is common to the door ECU 52 in that the presence / absence of the obstacle, the distance Lh between the rear end of the hinge door 26 and the obstacle is calculated based on the output of the obstacle sensor 54, and the required movement amount L of the sliding door 28 is calculated. . This door ECU 62 is electrically connected to the front seat detection sensor 64, and is provided that an ON signal is input from the front seat detection sensor 64 in addition to an open signal input from the courtesy switch 36. Further, the electric opening / closing device 32 is operated to move the slide door 28 to the rear side. That is, in the entrance / exit opening / closing devices 10 and 50 according to the first and second embodiments, the position of the front seat 22 is a control target to be automatically moved, but the entrance / exit opening / closing according to the third embodiment is performed. In the device 60, the position of the front seat 22 is handled as trigger information when the slide door 28 is moved.

  Other configurations of the entrance / exit opening / closing device 60 are the same as those of the entrance / exit opening / closing device 10.

  Next, the operation of the third embodiment will be described with reference to the flowchart shown in FIG. The operation from step S20 to step S26 in the flowchart shown in FIG. 10 is exactly the same as the operation from step S20 to step S26 indicated by the same reference numerals in FIG.

  When the door ECU 62 calculates the required movement amount L in step S26, the door ECU 62 proceeds to step S40. In step S40, it is determined whether or not the hinge door 26 is opened based on an input signal from the courtesy switch 36. If no opening signal is input from the courtesy switch 36, it is determined that the hinge door 26 has not been opened, and the process returns to step S20. If an open signal is input from the courtesy switch 36, that is, if it is determined that the hinge door 26 has been opened, the process proceeds to step S42.

  In step S42, whether or not the front seat 22 has been slid from the normal position to the boarding / exiting position based on the input signal from the front seat detection sensor 64, that is, whether there is an intention to get off the passenger in the front seat 22 It is determined whether or not. When the ON signal is not input from the front seat detection sensor 64, it is determined that there is no intention to get off the passenger in the front seat 22, and the process returns to step S20. If an ON signal is input from the front seat detection sensor 64, that is, if it is determined that the occupant of the front seat 22 is willing to get off, the process proceeds to step S44. In step S44, by operating the electric opening / closing device 32, the slide door 28 is moved to the rear side by a distance Ls that is equal to or greater than the necessary movement amount L.

  As a result, the vehicle S is moved to a wide open portion in the entrance opening 16 by the front seat 22 being retracted to a predetermined position by the occupant and the slide door 28 automatically moving to the rear side by the distance Ls. A state (front state corresponding to FIG. 3) in which the front seat is located. Thus, in the third embodiment in which the front seat 22 is moved rearward for the purpose of the occupant, the front seat 22 is automatically moved rearward, although the operation is different from the second embodiment, but the final It will be the same state when getting on and off. Therefore, the entrance / exit opening / closing device 60 according to the third embodiment can basically obtain the same effect as the entrance / exit opening / closing device 50 according to the second embodiment.

  Moreover, in the entrance / exit opening / closing device 60, when the passenger of the front seat 22 opens the hinge door 26 without intention to get off, the slide door 28 is prevented from being moved rearward carelessly. A front seat for automatically moving the front seat 22 to a position suitable for getting off is detected in order to detect that the occupant moves the front seat 22 to a boarding / alighting position suitable for getting off. A simple configuration in which the sheet driving device 40 is not provided can be achieved.

  As described above, in the entrance / exit opening / closing device 60 according to the third embodiment, by operating the hinge door 26, the entrance 16 for the entrance / exit of the vehicle body 12 can be opened so that a passenger in the front seat can get on / off. In addition, the boarding and alighting ability of the front seat occupant is good.

  In each of the above embodiments, an example in which the front seat is moved backward when there is an obstacle is shown. However, the present invention is not limited to this, and for example, the front seat 22 is seated. It is good also as a structure which a passenger | crew rotates in the direction which faces an outer side. Further, the movement of the front seat 22 may be prohibited or the amount of movement may be limited in relation to the rear seat 24.

  Moreover, in the said 2nd and 3rd embodiment, although opening width L0, L1 along the front-back direction of the motor vehicle S was used for calculation of the required moving amount L of the slide door 28, this invention is not limited to this, For example, depending on the thickness and shape of the hinge door 26 and the slide door 28 and the shape of the opening surface of the opening 16 for getting on and off the vehicle body 12, the required movement amount L can be set using the dimension in the direction intersecting the front-rear direction of the automobile S You may calculate (evaluate boarding / alighting property).

  Furthermore, in each said embodiment, it was set as the structure which judges whether the pivotable amount of the hinge door 26 is more than a threshold value based on the output of the obstacle sensors 38 and 54, or obtained the pivotable amount itself. The present invention is not limited to this. For example, a rotation angle sensor that directly detects the rotation amount of the hinge door 26 is provided around the hinge shaft 30, and the actual rotation angle of the hinge door 26 (the opening width of the front opening 16A) is predetermined. When it is determined that the value is less than or equal to the value, the electric switchgear 32 may be operated.

  Furthermore, in each of the above embodiments, when the hinge door 26 cannot be rotated to the open position (the rotation limit on the arrow A side), the slide door 28 is automatically moved to the rear side (the opening width L0 is set to the hinge door). However, the present invention is not limited to this, and the hinge door 26 does not reach the open position but is within a range where a sufficient opening width for getting on and off can be obtained. When is located, the slide door 28 may be set not to move backward. In other words, the opening position that is the mechanical rotation limit of the hinge door 26 does not need to coincide with the opening position that is a threshold value for determining whether the sliding door 28 is required to operate.
