Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle that cooperates with another vehicle that turns while tilting an occupant, and that turns and runs parallel with an occupant of its own vehicle, and more particularly to a vehicle that can improve the comfort of the occupant. Is.

  In recent years, in view of the problem of depletion of energy resources, there has been a strong demand for fuel saving of vehicles. Accordingly, various studies have been conducted to reduce fuel consumption by reducing the size of vehicles. For example, as disclosed in Japanese Patent Application Laid-Open No. 2005-145296, it can be said that the configuration in which the vehicle is configured as a single-seat two-wheeled vehicle is the most efficient in terms of fuel saving by reducing the size of the vehicle.

  However, a vehicle that has been downsized to reduce fuel consumption is lightweight and has a narrow wheel tread width, so the turning inner wheel side tends to float due to centrifugal force during turning, and if the vehicle does not decelerate sufficiently, the vehicle rolls over. .

  Therefore, the inventor of the present application has reached a technology that uses a structure in which an occupant part on which an occupant gets in is inclined toward the turning inner wheel (however, not known at the time of filing this application). According to this technique, the center of gravity position of the vehicle can be moved to the turning inner wheel side by inclining the occupant riding the occupant portion toward the turning inner wheel side, and accordingly, the resistance force against the centrifugal force is increased accordingly. Thus, it is possible to prevent the turning inner ring from floating up.

By the way, it can be said that a single-seater vehicle is the most efficient for reducing fuel consumption by downsizing the vehicle. On the other hand, for example, when two people go out, each single-seat vehicle must be operated. It can be said that it is extremely complicated. For this reason, a technique has been developed in which two or more vehicles are linked and run together to link each of the vehicles (however, not known at the time of filing this application).
JP 2005-145296 A

  However, when each vehicle is run side by side as a running mode in the linked running, if the above-described technique (a structure in which the occupant part is inclined toward the turning inner wheel) is employed to prevent the turning inner wheel from lifting, There was a problem that communication between passengers was impaired and comfort was impaired.

  That is, when the occupant part tilts toward the turning inner wheel, the eyes of the occupant riding on the occupant part are directed downward toward the inside of the turn, and upward toward the outside of the turn. . For this reason, an occupant of a vehicle located on the inside of the turn must communicate with the appearance of looking down on an occupant of the vehicle located on the outside of the turn, while an occupant of the vehicle located on the outside of the turn You must communicate in a fashion that looks up to the crew.

  The present invention has been made in order to solve the above-described problems, and relates to a vehicle that turns in parallel with another vehicle that turns while leaning the occupant, turns the occupant of its own vehicle, It aims at providing the vehicle which can aim at the improvement of a passenger | crew's comfort.

  In order to solve this object, a vehicle according to claim 1 is a vehicle that turns with the occupant tilted and runs in parallel with another vehicle that turns with the occupant tilting, and the occupant is on the vehicle. And a support means for supporting the occupant part so as to be able to move up and down, and an elevating means for matching the relative height positions of the occupant part and the occupant part of the other vehicle by driving the support means up and down. It is equipped with.

  The vehicle according to claim 2 comprises turning information receiving means for receiving turning information from the other vehicle in the vehicle according to claim 1, wherein the lifting means is received from the other vehicle by the turning information receiving means. The support means is driven up and down according to the turning information.

  According to a third aspect of the present invention, in the vehicle according to the second aspect, the turning information receiving means uses, as the turning information, an up / down driving amount of the supporting means or an operation amount based on a turning operation of the other vehicle. Is to be received from.

  According to a fourth aspect of the present invention, there is provided the vehicle according to the second or third aspect, further comprising: other vehicle position information detecting means for detecting position information of the other vehicle, wherein the elevating means is the other vehicle position information detecting means. The support means is driven up and down in accordance with the position information of the other vehicle detected by the turning information and the turning information received by the turning information receiving means.

  According to the vehicle of the first aspect, when the support means is driven up and down by the lifting means, the occupant portion is lifted and lowered by the lift driving of the support means. Thereby, even in the case of running in parallel with another vehicle turning with the occupant tilted, by moving the occupant part up and down, the relative height position of the occupant part and the occupant part of the other vehicle, for example, The height position of the seat on which the occupant sits and the height position of the occupant's eyes can be matched. Therefore, communication must be carried out in such a way that the vehicle occupant located inside the turn looks down at the vehicle occupant located outside the turn, or the vehicle occupant located outside the turn looks up at the vehicle occupant located inside the turn. There is an effect that it is possible to eliminate the discomfort to the occupant that must be done and to improve the comfort of the occupant.

  According to the vehicle of the second aspect, in addition to the effect achieved by the vehicle of the first aspect, when turning information is received from the other vehicle by the turning information receiving means, the support means is driven to move up and down according to the received turning information. The passenger part is raised and lowered. Accordingly, the occupant portion can be lifted and lowered in synchronization with the inclination of the occupant of the other vehicle, and the synchronization accuracy between the raising and lowering of the occupant portion and the inclination of the occupant of the other vehicle can be ensured. .

  According to the vehicle of the third aspect, in addition to the effect produced by the vehicle of the second aspect, the up / down driving amount of the support means or the operation amount based on the turning operation of the other vehicle is received as turning information. Thus, when the elevation drive amount of the support means is received as turning information, it is not necessary to calculate the elevation drive amount of the support means by merely receiving the elevation drive amount of the support means by the turning information receiving means. Thus, there is an effect that the control burden can be reduced.

  On the other hand, when the operation amount based on the turning operation of the other vehicle is received as turning information, it calculates the driving amount of the support means by itself and shares the control burden with the other vehicle. Since the occupant part can be raised and lowered, there is an effect that the time lag between the raising and lowering of the occupant part and the inclination of the occupant of the other vehicle can be suppressed.

  According to the vehicle according to claim 4, in addition to the effect produced by the vehicle according to claim 2 or 3, when the position information of the other vehicle is detected by the other vehicle position information detection means, the detected position information of the other vehicle In accordance with the turning information received by the turning information receiving means, the supporting means is driven up and down to raise and lower the occupant portion. As a result, the occupant portion can be raised and lowered by the amount of elevation according to the relative position with respect to the other vehicle, so that the relative height position with the occupant portion of the other vehicle can be matched with high accuracy. is there.

  According to the vehicle of the fifth aspect, in addition to the effect produced by the vehicle according to any one of the first to fourth aspects, the position information of the own vehicle detected by the own vehicle position information detecting means and the operation amount detecting means are detected. At least one of the operation amount based on the turning operation or the up / down driving amount of the support means is transmitted to the other vehicle by the turning information transmission means as turning information. As a result, even when the occupant leans and turns in parallel with another vehicle that turns, the relative height position of the occupant portion of the other vehicle and the occupant portion of the host vehicle can be raised and lowered For example, the height position of the seat on which the occupant is seated and the height position of the occupant's eyes can be matched. Therefore, communication must be carried out in such a way that the vehicle occupant located inside the turn looks down at the vehicle occupant located outside the turn, or the vehicle occupant located outside the turn looks up at the vehicle occupant located inside the turn. There is an effect that it is possible to eliminate the discomfort to the occupant that must be done and to improve the comfort of the occupant.

  Next, the wheel support device 30 will be described with reference to FIGS. 3 and 4. FIG. 3 is a front view of the wheel support device 30, and FIG. 4 is a top view of the wheel support device 30. In FIG. 3, for ease of understanding, the drawing is simplified and the footrest 11c is not shown, and the left and right wheels 12L and 12R are viewed in cross section. In FIG. 4, the occupant portion 11 is not shown, and a part of the occupant support member 40 and the left and right wheels 12L and 12R are viewed in cross section.

  As described above, the R motor 52R is a driving device for applying a rotational driving force to the right wheel 12R. As shown in FIGS. 3 and 4, the outer side of the passenger vehicle 10 (arrow R side). Are provided with a hub 52a and an upper pivot support plate 52b and a lower pivot support plate 52c on the inner side (arrow L side) of the occupant vehicle 10, respectively. Since the R motor 52R and the L motor 52L have the same configuration, the L motor 52L is assigned the same reference numeral and the description thereof is omitted.

  The hub 52a is a part to which the wheel 12Ra of the right wheel 12R is fastened and fixed by a hub nut and a hub bolt, and is formed in a disc-like body concentric with the axis of the drive shaft of the R motor 52R. When the drive shaft of the R motor 52R is rotationally driven, the rotation is transmitted to the wheel 12Ra via the hub 52a, and as a result, the right wheel 12R is rotationally driven.

  The upper shaft support plate 52b and the lower shaft support plate 52c are members for supporting the end portions of the upper link 31 and the lower link 32, respectively. As shown in FIGS. It is fixed to the side of the arrow L by welding.

  The upper link 31 and the lower link 32 are members for constituting a four-link parallel link mechanism together with the R motor 52R and the L motor 52L, and are configured in the same shape as a substantially rectangular plate-like body in front view. ing. According to the wheel support device 30 configured as described above, both ends of the upper link 31 are rotatably supported by the upper shaft support plates 52b of the R motor 52R and the L motor 52L, respectively. Both ends of the lower link 32 are rotatably supported by the lower shaft support plate 52c of the R motor 52R and the L motor 52L, respectively, so that the upper link 31, the lower link 32, the R motor 52R, and the L motor 52L The wheel support device 30 is configured as a four-node parallel link mechanism. Therefore, the camber angle can be given to the left and right wheels 12L and 12R by inclining the wheel support device 30.

  Thus, since the R motor 52R and the L motor 52L are configured to serve as the rotation drive device 52 and the wheel support device 30, the number of parts can be reduced and the structure can be simplified. As a result, it is possible to reduce weight and reduce parts / assembly costs.

  As shown in FIGS. 3 and 4, an F actuator 53 </ b> F and a B actuator 53 </ b> B are provided on the front side (arrow F side) and the rear side (arrow B side) of the wheel support device 30, respectively. As described above, the F actuator 53F and the B actuator 53B are drive devices for inclining the wheel support device 30, and both ends thereof are connected to joint portions of the wheel support device 30 that are not adjacent to each other.

  That is, as shown in FIGS. 3 and 4, the F actuator 53F has its lower end (main body side) supported on the lower shaft support plate 52c of the R motor 52R via the support shaft 80Fc, while its upper end side. The (rod side) is pivotally supported on the upper pivot support plate 52b of the L motor 52L via the support shaft 80Fb. As a result, the F actuator 53F is knocked on the diagonal line of the wheel support device 30.

  As shown in FIG. 4, the B actuator 53B has its lower end (main body side) supported on the lower shaft support plate 52c of the L motor 52L via a support shaft 80Bd, while its upper end side (rod side). ) Is supported on the upper shaft support plate 52b of the R motor 52R via the support shaft 80Ba. As a result, the B actuator 53 </ b> B is knocked on the diagonal line of the wheel support device 30. That is, the F actuator 53F and the B actuator 53B are arranged in a direction crossing each other.

  As described above, since the F actuator 53F and the B actuator 53B are arranged so as to intersect with each other, the wheel support device 30 is equal in any direction compared to the case where they are arranged in the same direction. The tilting can be performed by the driving force, and the tilt driving can be stabilized. In the present embodiment, the wheel support device 30 is inclined by two actuators (F actuator 53F and B actuator 53B), but the two actuators (F actuator 53F and B actuator 53B) are included. You may comprise only any one actuator.

  As shown in FIGS. 3 and 4, springs 60 </ b> F and 60 </ b> B are disposed on the front side (arrow F side) and the rear side (arrow B side) of the wheel support device 30, respectively. The springs 60 </ b> F and 60 </ b> B are members for urging the wheel support device 30 to return to the neutral position even when the wheel support device 30 is inclined in any direction, and are metal coil springs. Are configured in the same shape.

  Both ends of these springs 60F and 60B are connected to joint portions of the wheel support device 30 that are not adjacent to each other, as in the case of the F actuator 53F and the B actuator 53B described above.

  That is, as shown in FIGS. 3 and 4, the lower end of the spring 60F is pivotally supported by the lower shaft support plate 52c of the L motor 52L via the support shaft 80Fd, while the upper end of the spring 60F is the upper shaft of the R motor 52R. The support plate 52b is pivotally supported via a support shaft 80Fa. Thereby, the spring 60F is knocked on the diagonal line of the wheel support device 30 while being orthogonal to the F actuator 53F.

  As shown in FIG. 4, the lower end of the spring 60B is supported by the lower shaft support plate 52c of the R motor 52R via the support shaft 80Bc, while the upper end side of the spring 60B is the upper shaft support plate 52b of the L motor 52L. Is supported by a support shaft 80Bb. As a result, the spring 60B is struck on the diagonal line of the wheel support device 30 while being orthogonal to the B actuator 53B.

  Thus, even if the wheel support device 30 is provided with the springs 60F and 60B and the wheel support device 30 is inclined in any direction, the wheel support device 30 can be urged to return to the neutral position. It is unnecessary to always drive the actuator 53F and the B actuator 53B to hold the wheel support device 30 in the neutral position. Therefore, control and driving for holding the wheel support device 30 in the neutral position are unnecessary, and the control cost and driving cost can be reduced.

  Next, the occupant support member 40 will be described with reference to FIGS. 3 and 4. The passenger | crew part support member 40 is a member which connects the wheel support apparatus 30 and the passenger | crew part 11 as above-mentioned, and is provided with the 1st member 41 and the 2nd member 42 as shown in FIG.3 and FIG.4. ing.

It is formed in a letter shape, and its upper end is connected to the second member 42. The 2nd member 42 is a member for supporting the passenger | crew part 11 (seat 11a) from the bottom face side (arrow D side, refer FIG. 3), and is formed in the front view substantially U shape from the steel material.

  According to this occupant support member 40, the first member 41 is rotatably supported at the substantially central part of the upper link 31 and the lower link 32, so that the occupant part 11 is accompanied by the inclination of the wheel support device 30. Can be tilted (see FIG. 5B).

  Next, with reference to FIG. 5, operation | movement of the wheel support apparatus 30 comprised as mentioned above is demonstrated.

And an electric motor that can be extended and retracted by using a mechanism in which the screw shaft and the nut move relative to each other when the screw shaft or the nut is rotationally driven by the electric motor.

  As described above, the information communication device 154 transmits and receives various information such as the traveling state of the occupant vehicle 10 instructed by the occupant P from the joystick device 51 to other vehicles (for example, the occupant vehicle 10) existing within a predetermined distance. The apparatus mainly includes an infrared port 154a for transmitting and receiving information by infrared rays, and a processing circuit (not shown) for outputting information transmitted and received by the infrared port 154a to the CPU 171.

Examples include sensors (not shown).

  Next, the wheel support device 130 will be described with reference to FIG. FIG. 7A is a front view of the wheel support device 130, and FIG. 7B is a top view of the wheel support device 130. In FIG. 7A, for ease of understanding, the drawing is simplified to omit the illustration of the body 111, and the left and right wheels 112L and 112R are viewed in cross section. In FIG. 7B, the body 111 is not shown, and a part of the connecting member 140 and the left and right wheels 12L and 12R are viewed in cross section.

  As described above, the wheel support device 130 is a device for supporting the left and right wheels 112L and 112R. As shown in FIG. 7, the R motor 152R and the L motor 152L, and the R motor 152R and the L motor 152L. The upper link 131 is pivotally supported at both ends thereof, and the lower link 132 is pivotally supported at both ends by the R motor 152R and the L motor 152L, similar to the upper link 131.

  As described above, the R motor 152R is a driving device for applying a rotational driving force to the right wheel 112R. As shown in FIG. 7, the R motor 152R is a hub on the outer side (the arrow R side) of the body vehicle 110. On the inner side (the arrow L side) of the body vehicle 110, an upper shaft support plate 152b and a lower shaft support plate 152c are respectively disposed. Since the R motor 152R and the L motor 152L have the same configuration, the L motor 152L is assigned the same reference numeral and the description thereof is omitted.

  The hub 152a is a portion where the wheel 112Ra of the right wheel 112R is fastened and fixed by a hub nut and a hub bolt, and is formed in a disc shape concentric with the axis of the drive shaft of the R motor 152R. When the drive shaft of the R motor 152R is rotationally driven, the rotation is transmitted to the wheel 112Ra via the hub 152a, and as a result, the right wheel 112R is rotationally driven.

  The upper shaft support plate 152b and the lower shaft support plate 152c are members for supporting the end portions of the upper link 131 and the lower link 132, respectively. As shown in FIG. 7, the side surface of the R motor 152R (the side surface of the arrow L) ) Is fixed by welding.

  The upper link 131 and the lower link 132 are members for constituting a four-link parallel link mechanism together with the R motor 152R and the L motor 152L, and are configured in the same shape as a substantially rectangular plate-like body in front view. ing. According to the wheel support device 130 configured as described above, both ends of the upper link 131 are rotatably supported by the upper shaft support plates 152b of the R motor 152R and the L motor 152L, respectively, and similarly to the upper link 131. The both ends of the lower link 132 are rotatably supported by the lower shaft support plate 152c of the R motor 152R and the L motor 152L, respectively, so that the upper link 131 and the lower link 132 and the R motor 152R and the L motor 152L The wheel support device 130 is configured as a four-joint parallel link mechanism. Therefore, camber angles can be given to the left and right wheels 112L and 112R by inclining the wheel support device 130.

  Thus, since the R motor 152R and the L motor 152L are configured to serve as the rotation drive device 152 and the wheel support device 130, the number of components can be reduced and the structure can be simplified. As a result, it is possible to reduce weight and reduce parts / assembly costs.

  Next, the connecting member 140 will be described with reference to FIG. FIG. 8A is a front view of the connecting member 140, and FIG. 8B is a side view of the connecting member 140. As described above, the connecting member 140 is a member that connects the wheel support device 130 and the body 111, and includes a first member 141 and a second member 142 as shown in FIG. The first member 141 is a member that is pivotally supported by the upper link 131 and the lower link 132 of the wheel support device 130, and is formed in a substantially U shape in a side view as shown in FIG. Is connected to the second member 142. As shown in FIG. 8A, the through hole 141a drilled above the first member 141 (arrow U side) is a part that is pivotally supported by the upper link 131, and the first member 141 has The through-hole 141b drilled downward (arrow D side) is a part pivotally supported by the lower link 132.

  The second member 142 is a member that is pivotally supported by the body 111 (the upper frame member 111a and the lower frame member 111b), and is formed in a substantially T shape in a side view. As shown in FIG. 8A, the through hole 142a drilled above the second member 142 (arrow U side) is a part pivotally supported by the upper frame member 111a of the body 111. The through hole 142b drilled below the two members 142 (arrow D side) is a part that is pivotally supported by the lower frame member 111b of the body 111.

  According to the connecting member 140, the first member 141 is rotatably supported at substantially the center of the upper link 131 and the lower link 132, and the second member 142 is supported by the upper frame member 111a and the lower frame member of the body 111. By being pivotally supported by 111b, the wheel support device 130 can be tilted along with the deformation of the body 111, and as a result, camber angles can be imparted to the left and right wheels 112L, 112R ( (See FIG. 9B).

  Next, the operation of the wheel support device 130 configured as described above will be described with reference to FIG. FIG. 9 is a schematic diagram for explaining the tilting operation of the wheel support device 130, corresponding to the front view of the wheel support device 130, in which (a) is in a neutral position and (b) is tilted. Each state is shown. In FIG. 9, the L motor 152L, the R motor 152R, and the like are schematically illustrated, and the flat plates 111d, 111e, and the like are not illustrated.

  As shown in FIG. 9A, when the body 111 is in the neutral position, the inclination angle of the connecting member 140 is 0 °. Further, the inclination angle of the wheel support device 130 is also 0 °, and the camber angles of the left and right wheels 112L and 112R are 0 °. When the C actuator 153C is driven to extend, as shown in FIG. 9B, the body 111 is given a predetermined inclination angle θB, and the connecting member 140 is also given an equivalent inclination angle θB. . Thereby, the wheel support device 130 is inclined, and predetermined camber angles θR and θL are given to the left and right wheels 112L and 112R. In the present embodiment, since the wheel support device 130 is configured as a parallel link mechanism, the camber angles θR, θL and the inclination angle θB all have the same value.

  Next, processing executed by the control device 70 of the passenger vehicle 10 will be described with reference to FIG. FIG. 10 is a flowchart showing a turning control process executed by the control device 70 of the occupant vehicle 10. Here, the description of FIG. 10 will be made with reference to FIG. 12 as appropriate. FIG. 12A is a front view of the linkage vehicle 1 and shows a state during a left turn. FIG. 12B is a front view of the linkage vehicle in which the body of the body vehicle is not deformed, and shows a state of turning left as in FIG. That is, both FIG. 12A and FIG. 12B show a state where the vehicle travels forward toward the front side of the paper and turns toward the right side of the paper. In FIG. 12B, the body of the body vehicle is schematically shown. In FIG. 12A, for ease of understanding, the drawings are simplified to omit illustration of the flat plates 111d and 111e, and only main components are denoted by reference numerals.

  The turning control process shown in FIG. 10 is a process that is repeatedly executed by the CPU 71 (for example, at intervals of 0.2 ms) while the control device 70 is powered on. In relation to the turning control process, the CPU 71 first determines whether or not to perform the initiative traveling as the initiative vehicle in the associated traveling with the body vehicle 110, that is, whether or not the traveling changeover switch 50 is turned on (S11). As a result, if it is determined that the travel changeover switch 50 is not turned on, that is, is turned off (S11: No), the initiative traveling as the initiative vehicle is not performed in the associated traveling with the body vehicle 110. Therefore, this turning control process is terminated.

  On the other hand, in the process of S11, when it is determined that the travel changeover switch 50 is turned on (S11: Yes), this means that the initiative traveling as the initiative vehicle is performed in the association traveling with the body vehicle 110. Next, the relative position with respect to the body vehicle 110 is detected by the position information detection device 55 (S12), and the process proceeds to S13 and subsequent steps.

  Next, it is determined whether or not there is a turning instruction from the occupant P, that is, whether or not the joystick device 51 (operation lever) is operated in the left-right direction (S13). As a result, when it is determined that the joystick device 51 is not operated in the left-right direction (S13: No), this means that there is no turning instruction by the occupant P, and thus this turning control process is terminated. Note that the operation of the joystick device 51 in the left-right direction is detected by the left-right sensor 51b as described above.

  On the other hand, in the process of S13, when it is determined that the joystick device 51 is operated in the left-right direction (S13: Yes), this means that there is a turning instruction from the occupant P, so the joystick device 51 ( The operation state (operation amount) in the front / rear direction of the operation lever) and the operation state (operation amount) in the left / right direction are detected by the front / rear sensor 51a and the left / right sensor 51b (S14, S15), and the process proceeds to S16 and subsequent steps. .

  In the processing after S16, first, based on the operation state (operation amount) in the front-rear direction and the operation state (operation amount) in the left-right direction of the joystick device 51 (operation lever) detected in the processing of S14 and S15, The rotation speeds of the L motor 52L and the R motor 52R are calculated (S16). That is, the rotation speeds of the L motor 52L and the R motor 52R are calculated so that the occupant vehicle 10 can travel in the traveling direction and the traveling speed corresponding to the operation state of the joystick device 51 in the front-rear direction. The differential between the L motor 52L and the R motor 52R (the difference between the rotational speeds of the left and right wheels 12L, 12R) is calculated so that the occupant vehicle 10 can turn with the turning direction and the turning radius corresponding to the operation state in the direction.

  Next, the passenger vehicle 10 is turned based on the operation state (operation amount) in the front-rear direction and the operation state (operation amount) in the left-right direction of the joystick device 51 (operation lever) detected in the processes of S14 and S15. The centrifugal force generated in this case is calculated, and the inclination angle θA (see FIG. 5B) toward the turning inner wheel of the occupant 11 that balances the centrifugal force is calculated (S17). However, in the present embodiment, as described above, since the inclination angle θA of the occupant portion 11 and the camber angles θR and θL all have the same value (see FIG. 5B), the camber angle θR or the camber angle θL is set to be the same. It may be calculated. Note that a formula for calculating the centrifugal force generated in the occupant vehicle 10 and a formula for calculating the inclination angle θA of the occupant section 11 are stored in advance in the ROM 72 (not shown).

  After calculating the inclination angle θA of the occupant 11, whether or not the calculated inclination angle θA is a value within an allowable range, that is, an inclination angle that allows the wheel support device 30 to be structurally inclined, and Then, it is determined whether or not the occupant vehicle 10 has an inclination angle that does not fall inside the turn (S18). If the calculated inclination angle θA is within the allowable range (S18: Yes), the process proceeds to S20. However, the calculated inclination angle θA exceeds the inclination angle that can be inclined due to the structure of the wheel support device 30. If the inclination angle of the occupant vehicle 10 is inclining (S18: No), the inclination angle θA of the occupant portion 11 can be inclined due to the structure of the wheel support device 30 or the occupant vehicle 10 is overturned. After recalculating the limit inclination angle that can be avoided (S19), the process proceeds to S20 and subsequent steps. Note that the tilt angle that can be tilted due to the structure of the wheel support device 30 and the limit tilt angle at which the passenger vehicle 10 can be prevented from falling are stored in advance in the ROM 72 (not shown).

  In the processing after S20, first, based on the operation state (operation amount) in the front-rear direction and the operation state (operation amount) in the left-right direction of the joystick device 51 (operation lever) detected in the processing of S14 and S15, The rotation speeds of the L motor 152L and the R motor 152R of the body vehicle 110 are calculated (S20). That is, the rotational speeds of the L motor 152L and the R motor 152R are calculated so that the body vehicle 110 can travel in the traveling direction and the traveling speed corresponding to the operation state of the joystick device 51 in the front-rear direction, and The differential between the L motor 152L and the R motor 152R (the difference in the number of revolutions of the left and right wheels 112L and 112R) is calculated so that the body vehicle 110 can turn with the turning direction and the turning radius corresponding to the operation state in the direction.

  Next, the inclination angle θB (see FIG. 9B) of the body 111 is calculated based on the inclination angle θA of the occupant portion 11 calculated in the processing of S17 or S19 (S21). The calculation of the inclination angle θB of the body 111 based on the inclination angle θA of the occupant part 11 is a table that stores a relational expression between the inclination angle θA of the occupant part 11 and the inclination angle θB of the body 111 stored in advance in the ROM 72. (Not shown). However, the inclination angle θB of the body 111 stored in this table is set such that the inclination angle at which the body 111 can be structurally inclined is the maximum inclination angle of the body 111.

  After the inclination angle θB of the body 111 is calculated, the occupant 11 and the body 111 are brought into contact with or contacted at the calculated inclination angle θB of the body 111 based on the relative position with the body vehicle 110 detected in the process of S12. It is determined whether or not fear can be avoided (S22). The determination as to whether or not the occupant part 11 and the body 111 are in contact with each other or the possibility of contact can be avoided is based on whether the relative inclination angle between the occupant part 11 and the body 111 is stored in the ROM 72 in advance. When the predetermined relative inclination angle with respect to 111 is exceeded, that is, when the interval between the occupant portion 11 and the body 111 is equal to or less than the predetermined interval, it is determined that the occupant portion 11 and the body 111 may contact or contact each other. .

  As a result of the process of S22, when it is determined that the contact between the occupant unit 11 and the body 111 can be avoided (S22: Yes), the process proceeds to the process after S24, but the occupant unit 11 and the body 111 are moved. If it is determined that the contact with the vehicle or the risk of contact cannot be avoided (S22: No), the inclination angle θB of the body 111 is recalculated based on the relative position to the body vehicle 110 detected in the process of S12. Later (S23), the process proceeds to S24 and subsequent steps. Note that the recalculation of the inclination angle θB of the body 111 based on the relative position with the body vehicle 110 is a table (not shown) that stores a correction coefficient corresponding to the relative distance from the body vehicle 110 stored in advance in the ROM 72. Is performed by multiplying the inclination angle θB of the body 111 calculated in the process of S21 by a correction coefficient.

  In the processing after S24, first, the vehicle speed of the L motor 152L and the R motor 152R calculated in the processing of S20 and the inclination angle θB of the body 111 calculated in the processing of S21 or S23 are determined by the information communication device 54 to the body vehicle 110. (S24). Next, based on the rotation speeds of the L motor 52L and the R motor 52R calculated in the process of S16, drive control (rotation speed control) of the rotation drive device 52 (L motor 52L and R motor 52R) is performed (S25). Based on the inclination angle θA of the occupant portion 11 calculated in the processing of S17 or S19, drive control (control of the expansion / contraction amount) of the actuator device 53 (F actuator 53F and B actuator 53B) is performed (S26), and this turning control is performed. The process ends.

  As a result, the left and right wheels 12L and 12R can be differentiated, and as shown in FIG. 12A, camber angles are given to the left and right wheels 12L and 12R, and the left and right wheels 12L and 12R are camber thrust. Therefore, the occupant vehicle 10 can be turned based on the turning instruction from the occupant P.

  Further, in this case, the occupant support member 40 connected to the occupant unit 11 is moved to the left and right wheels 12L and 12R simultaneously with the inclination of the left and right wheels 12L and 12R as the wheel support device 30 is inclined. It can be inclined in the same direction. As a result, as shown in FIG. 12 (a), the occupant portion 11 can be tilted toward the turning inner wheel and the center of gravity of the occupant vehicle 10 can be moved toward the turning inner wheel. The counter force against the arrow A) can be increased, and lifting of the turning inner wheel (the left wheel 12L in FIG. 12A) can be prevented. As a result, the turning performance of the passenger vehicle 10 can be improved.

  Next, processing executed by the control device 170 of the body vehicle 110 will be described with reference to FIG. FIG. 11 is a flowchart showing a turning control process executed by the control device 170 of the body vehicle 110. Here, in the description of FIG. 11, the description will be made with reference to FIG.

  The turning control process shown in FIG. 11 is a process repeatedly executed by the CPU 171 (for example, at intervals of 0.2 ms) while the power of the control device 170 is turned on. Regarding the turning control process, the CPU 171 first determines whether the information communication device 154 has received the rotation speed of the L motor 152L and the R motor 152R and the inclination angle θB of the body 111 from the passenger vehicle 10 (S31). ). As a result, when it is determined that the signal has not been received (S31: No), the turning control process is terminated.

  On the other hand, if it is determined in S31 that it has been received (S31: Yes), then, based on the rotational speeds of the L motor 152L and the R motor 152R received in S31, the rotation drive device 152 (L Drive control (rotational speed control) of the motor 152L and the R motor 152R is performed (S32), and the body deformation device 153 (C actuator 153C) is driven based on the inclination angle θB of the body 111 received in the process of S31. Control (control of expansion / contraction amount) is performed (S33), and this turning control process is terminated.

  Accordingly, as shown in FIG. 12A, the body 111 can be deformed, so that even when the occupant 11 is tilted to the turning inner wheel side and is traveling in conjunction with the occupant vehicle 10 turning, By deforming the body 111 in accordance with the inclination of the occupant portion 11, it is possible to avoid contact between the occupant portion 11 and the body 111 or a risk of contact. Therefore, the occupant portion 11 of the occupant vehicle 10 can be tilted toward the turning inner wheel as much as necessary, so that the turning performance of the occupant vehicle 10 can be improved accordingly. Here, when the body 111 is not deformed, the occupant portion 11 and the body 111 may contact or contact each other as shown in part B of FIG.

  Further, in this case, with the deformation of the body 111, the connecting member 140 connected to the wheel support device 130 can be inclined in the same direction as the body 111 simultaneously with the deformation of the body 111. As a result, camber angles can be given to the left and right wheels 112L and 112R to generate camber thrust on the left and right wheels 112L and 112R, so that the body vehicle 110 can be turned. Further, as the body 111 is deformed, camber angles are given to the left and right wheels 112L and 112R, so that an actuator device for tilting the left and right wheels 112L and 112R becomes unnecessary, and the structure is simplified accordingly. Can be planned.

  As described above, according to the body vehicle 110 in the present embodiment, the body 111 is configured by the four-node parallel link mechanism, and the four-node parallel link mechanism is configured by the body deforming device 153 (C actuator 153C). Since the body 111 is deformed by being inclined, the structure for deforming the body 111 can be simplified. That is, by configuring the body 111 with a four-link parallel link mechanism, the body 111 can be deformed if there is only at least one actuator (C actuator 153C). As a result, it is possible to reduce the vehicle weight and reduce vehicle costs such as component costs and assembly costs.

  Further, since the body 111 is deformed by tilting the four-link parallel link mechanism by the body deforming device 153 (C actuator 153C), the body deforming device 153 (C actuator 153C) is driven according to the turning operation of the occupant vehicle 10. By controlling, the time lag between the inclination of the occupant portion 11 of the occupant vehicle 10 and the deformation of the body 111 can be suppressed.

  Furthermore, since the occupant vehicle 10 is configured to calculate the rotation speed of the L motor 152L and the R motor 152R of the body vehicle 110 and the inclination angle θB of the body 111, the body vehicle 110 is connected to the body 111 by the information communication device 154. The body deformation device 153 (C actuator 153C) can be driven and controlled by merely receiving the inclination angle θB without having to calculate the inclination angle θB of the body 111 by itself. Therefore, the control burden on the body vehicle 110 can be reduced.

  Next, a second embodiment will be described with reference to FIGS. FIG. 13 is a flowchart showing a turning control process executed by the control device 70 of the passenger vehicle 10 in the second embodiment, and FIG. 14 is executed by the control device 170 of the body vehicle 110 in the second embodiment. It is a flowchart which shows the turning control process.

  In the first embodiment, the case where the occupant vehicle 10 calculates the rotation speeds of the L motor 152L and the R motor 152R of the body vehicle 110 and the inclination angle θB of the body 111 has been described. In the second embodiment, The body vehicle 110 calculates the rotation speed of the L motor 152L and the R motor 152R and the inclination angle θB of the body 111 by itself. In addition, the same code | symbol is attached | subjected to the part same as 1st Embodiment, and the description is abbreviate | omitted.

  First, with reference to FIG. 13, the turning control process of the passenger vehicle 10 will be described. In the second embodiment, after the process of S18 or S19 is executed, the processes after S220 are executed.

  In the processing after S220, first, the operation state in the front-rear direction (operation amount) and the operation state in the left-right direction (operation amount) of the joystick device 51 (operation lever) detected in the processing in S14 and S15, and S17 or S19. The information communication device 54 transmits the inclination angle θA of the occupant section 11 calculated in the above process to the body vehicle 110 (S220).

  Next, based on the rotation speeds of the L motor 52L and R motor 52R calculated in the process of S16, drive control (rotation speed control) of the rotation drive device 52 (L motor 52L and R motor 52R) is performed (S221). Based on the inclination angle θA of the occupant portion 11 calculated in the processing of S17 or S19, drive control (control of the expansion / contraction amount) of the actuator device 53 (F actuator 53F and B actuator 53B) is performed (S222). The process ends.

  Next, turning control processing of the body vehicle 110 will be described with reference to FIG. In the second embodiment, first, the information communication device 154 uses the joystick device 51 (operation lever) to operate in the front-rear direction (operation amount) and the operation state in the left-right direction (operation amount). It is determined whether or not the inclination angle θA is received from the occupant vehicle 10 (S231). As a result, when it is determined that the information has not been received (S231: No), the turning control process is terminated.

  On the other hand, if it is determined in S231 that it has been received (S231: Yes), then the relative position with respect to the passenger vehicle 10 is detected by the position information detection device 155 (S232), and the process proceeds to S233 and subsequent steps. To do.

  In the processing after S233, first, based on the operation state in the front-rear direction (operation amount) and the operation state in the left-right direction (operation amount) of the joystick device 51 (operation lever) received in the processing of S231, the L motor The rotation speeds of 152L and R motor 152R are calculated (S233).

  Next, based on the inclination angle θA of the occupant part 11 received in the process of S231 and the relative position of the occupant vehicle 10 detected in the process of S232, the possibility of contact or contact between the occupant part 11 and the body 111 is avoided. It is determined whether or not it is possible (S234). It should be noted that the determination as to whether or not contact between the occupant part 11 and the body 111 can be avoided is based on a calculation formula (not shown) for calculating the distance between the occupant part 11 and the body 111 stored in advance in the ROM 172. ), When the distance between the occupant part 11 and the body 111 is equal to or smaller than the predetermined distance between the occupant part 11 and the body 111 stored in advance in the ROM 172, the occupant part 11 and the body 111 come into contact or contact with each other. Judge that there is a risk of doing.

  As a result of the process of S234, when it is determined that the contact between the occupant part 11 and the body 111 can be avoided (S234: Yes), the process proceeds to the process after S238, but the occupant part 11 and the body 111 are moved. If it is determined that the contact with the vehicle or the risk of contact cannot be avoided (S234: No), the inclination angle θB of the body 111 (see FIG. 9 (FIG. 9)) based on the inclination angle θA of the occupant 11 received in the process of S231. b)) is calculated (S235). The calculation of the inclination angle θB of the body 111 based on the inclination angle θA of the occupant part 11 is a table that stores a relational expression between the inclination angle θA of the occupant part 11 and the inclination angle θB of the body 111 stored in advance in the ROM 172. (Not shown). However, the inclination angle θB of the body 111 stored in this table is set such that the inclination angle at which the body 111 can be structurally inclined is the maximum inclination angle of the body 111.

  After the inclination angle θB of the body 111 is calculated, the occupant 11 and the body 111 are brought into contact with or contacted at the calculated inclination angle θB of the body 111 based on the relative position with the occupant vehicle 10 detected in the process of S232. It is determined whether or not fear can be avoided (S236). It should be noted that the determination as to whether or not the contact between the occupant part 11 and the body 111 can be avoided is based on whether the relative inclination angle between the occupant part 11 and the body 111 is stored in the ROM 172 in advance. When the predetermined relative inclination angle with respect to 111 is exceeded, that is, when the interval between the occupant portion 11 and the body 111 is equal to or less than the predetermined interval, it is determined that the occupant portion 11 and the body 111 may contact or contact each other. .

  As a result of the process of S236, when it is determined that the contact between the occupant part 11 and the body 111 can be avoided (S236: Yes), the process proceeds to the process after S238, but the occupant part 11 and the body 111 are moved. If it is determined that the contact with the passenger or the fear of contact cannot be avoided (S236: No), the inclination angle θB of the body 111 is recalculated based on the relative position to the passenger vehicle 10 detected in the process of S232. Later (S237), the process proceeds to S238 and subsequent steps. The recalculation of the inclination angle θB of the body 111 based on the relative position with respect to the occupant vehicle 10 is a table (not shown) that stores a correction coefficient corresponding to the relative distance from the occupant vehicle 10 stored in advance in the ROM 172. Is used by multiplying the inclination angle θB of the body 111 calculated in the process of S235 by the correction coefficient.

  In the processing after S238, drive control (rotational speed control) of the rotational drive device 152 (L motor 152L and R motor 152R) is performed based on the rotational speeds of the L motor 152L and R motor 152R calculated in the processing of S233. At the same time (S238), on the basis of the inclination angle θB of the body 111 calculated in the process of S235 or S237, drive control (control of the expansion / contraction amount) of the body deforming device 153 (C actuator 153C) is performed (S239). The process ends. When the process of S235 or S237 is skipped, the drive control of the body deformation device 153 (C actuator 153C) in the process of S239 is not performed.

  As described above, according to the body vehicle 110 in the present embodiment, the body vehicle 110 itself calculates the rotation speed of the L motor 152L and the R motor 152R and the inclination angle θB of the body 111. The vehicle 110 can calculate the inclination angle θB of the body 111 in parallel with the calculation of the inclination angle θA of the occupant section 11 by the occupant vehicle 10. Thereby, the time lag in drive control with the actuator device 53 (F actuator 53F and B actuator 53B) and the body deformation device 153 (C actuator 153C) can be suppressed.

  Further, the relative position with respect to the passenger vehicle 10 detected by the position information detection device 155, the operation state (operation amount) in the front-rear direction of the joystick device 51 (operation lever) received by the information communication device 154, and the operation in the left-right direction Based on the state (amount of operation), whether or not the occupant portion 11 and the body 111 are in contact with each other or can be prevented from being touched (whether or not the interval between the occupant portion 11 and the body 111 is equal to or less than a predetermined interval). When it is determined by the contact determination means (S234), the contact determination means (S234) cannot avoid contact or contact between the occupant part 11 and the body 111 (the interval between the occupant part 11 and the body 111 is equal to or less than a predetermined interval). ) (S234: No), the body 111 is deformed. Thereby, it is possible to prevent the body 111 from being unnecessarily deformed and to reduce the control cost. In addition, the body 111 is determined only when it is determined by the contact determination means (S234) that the occupant part 11 and the body 111 cannot be contacted or contacted (the distance between the occupant part 11 and the body 111 is equal to or less than a predetermined distance). Therefore, the durability of the body 111 can be improved accordingly.

  Furthermore, since the inclination angle θB of the body 111 can be calculated according to the inclination angle θA of the occupant part 11 received by the information receiving means 154 and the body 111 can be deformed, the contact or contact between the occupant part 11 and the body 111 is possible. The fear of doing so can be avoided with high accuracy.

  In the flowchart shown in FIG. 14 (turning control process), the contact determination means according to claim 4 corresponds to the process of S234.

  Next, a third embodiment will be described with reference to FIGS. 15 to 17. FIG. 15 is a front view of the linkage vehicle 200 in the third embodiment, and FIG. 16 is a flowchart showing a turning control process executed by the control device 70 of the passenger vehicle 10 in the third embodiment. FIG. 17A is a flowchart showing a turning control process executed by the control device 70 of the occupant vehicle 210, and FIG. 17B is executed by the control device 170 of the body vehicle 110 in the third embodiment. It is a flowchart which shows the turning control process. FIG. 15 shows a state where the occupant P gets on the occupant part 11 of the occupant vehicle 10 and the occupant Ps gets on the occupant part 11 of the occupant vehicle 210. In FIG. 15, the flat plates 111d and 111e are not shown.

  The linkage vehicle 1 in the first embodiment is composed of one occupant vehicle 10 and a body vehicle 110, and the case has been described in which the occupant vehicle 10 and the body vehicle 110 travel together. The third embodiment The linked vehicle 200 includes two occupant vehicles 10 and 210 and a body vehicle 110, and the two occupant vehicles 10 and 210 and the body vehicle 110 are configured to travel together. In addition, the same code | symbol is attached | subjected to the part same as 1st Embodiment, and the description is abbreviate | omitted. Further, since the occupant vehicle 10 and the occupant vehicle 210 have the same configuration, the occupant vehicle 210 is assigned the same reference numeral, and the description thereof is omitted.

  First, a schematic configuration of the linkage vehicle 200 will be described with reference to FIG. The linking vehicle 200 includes an occupant vehicle 10 on which the occupant P rides, an occupant vehicle 210 on which the occupant Ps rides, and the occupant P that covers the occupant portions 11 of the two occupant vehicles 10 and 210 and rides on the occupant portions 11. , Ps, and a body vehicle 110 having a body 111 for protecting Ps, and the two passenger vehicles 10 and 210 and the body vehicle 110 are configured to travel together.

  The occupant vehicle 210 uses the information communication device 54 (for example, the traveling direction, the traveling speed, the turning direction, or the turning radius) transmitted from the information communication device 54 (see FIG. 2) of the occupant vehicle 10. 2) and based on the received travel information, the rotation drive device 52 (L motor 52L and R motor 52R, see FIG. 2) and actuator device 53 (F actuator 53F and B actuator 53B, see FIG. 2) It is comprised so that it can drive | work with the passenger | crew vehicle 10 by driving-controlling.

  Next, with reference to FIG. 16, the turning control process of the passenger vehicle 10 will be described. In the third embodiment, first, it is determined whether or not the initiative traveling as the initiative vehicle is performed in the associated traveling with the passenger vehicle 210 and the body vehicle 110, that is, whether or not the traveling changeover switch 50 is turned on ( S311). As a result, when the travel changeover switch 50 is not turned on, that is, when it is determined that it is turned off (S311: No), the initiative traveling as the initiative vehicle in the linkage traveling with the occupant vehicle 210 and the body vehicle 110 is performed. Therefore, the turning control process is terminated.

  On the other hand, in the process of S311, when it is determined that the travel changeover switch 50 is turned on (S311: Yes), the initiative traveling as the initiative vehicle is performed in the associated traveling with the occupant vehicle 210 and the body vehicle 110. Therefore, the relative position between the passenger vehicle 210 and the body vehicle 110 is detected by the position information detection device 55 (S312), and the process proceeds to S313 and subsequent steps.

  Next, it is determined whether or not there is a turning instruction from the occupant P, that is, whether or not the joystick device 51 (operation lever) is operated in the left-right direction (S313). As a result, when it is determined that the joystick device 51 is not operated in the left-right direction (S313: No), this means that there is no turning instruction by the occupant P, and thus this turning control process is terminated. Note that the operation of the joystick device 51 in the left-right direction is detected by the left-right sensor 51b as described above.

  On the other hand, in the process of S313, when it is determined that the joystick device 51 is operated in the left-right direction (S313: Yes), it means that there is a turning instruction from the occupant P, so the joystick device 51 ( The operation state (operation amount) in the front / rear direction of the operation lever) and the operation state (operation amount) in the left / right direction are detected by the front / rear sensor 51a and the left / right sensor 51b (S314, S315), and the process proceeds to S316 and subsequent steps. .

  In the processing after S316, first, based on the operation state (operation amount) in the front-rear direction and the operation state (operation amount) in the left-right direction of the joystick device 51 (operation lever) detected in the processing of S314 and S315, The rotational speeds of the L motor 52L and the R motor 52R are sent out (S316). In the present embodiment, the calculated rotation speeds of the L motor 52L and R motor 52R, the rotation speeds of the L motor 52L and R motor 52R of the occupant vehicle 210, and the L motor 152L and R motor 152R of the body vehicle 110 are calculated. The number of rotations is the same value. However, it may be calculated individually.

  Next, the occupant vehicle 10 is turned based on the operation state (operation amount) in the front-rear direction and the operation state (operation amount) in the left-right direction of the joystick device 51 (operation lever) detected in the processes of S314 and S315. The centrifugal force generated in this case is calculated, and the inclination angle θA (see FIG. 5B) of the occupant portion 11 toward the turning inner wheel that is balanced with the centrifugal force is calculated (S317). In the present embodiment, the calculated inclination angle θA of the occupant section 11 and the inclination angle of the occupant section 11 of the occupant vehicle 210 are configured to have the same value. However, it may be calculated individually.

  After calculating the inclination angle θA of the occupant 11, whether or not the calculated inclination angle θA is a value within an allowable range, that is, an inclination angle that allows the wheel support device 30 to be structurally inclined, and Then, it is determined whether or not the occupant vehicles 10 and 210 have an inclination angle that does not fall inside the turn (S318). If the calculated inclination angle θA is within the allowable range (S318: Yes), the process proceeds to S320, but the calculated inclination angle θA exceeds the inclination angle that can be inclined due to the structure of the wheel support device 30. If it is the inclination angle that causes the occupant vehicle 10 or 210 to fall (S318: No), the inclination angle θA of the occupant portion 11 can be inclined due to the structure of the wheel support device 30 or the occupant vehicle 10, After recalculating the tilt angle to a limit that can avoid the fall of 210 (S319), the process proceeds to S320 and subsequent steps. Note that the tilt angle that can be tilted due to the structure of the wheel support device 30 and the limit tilt angle at which the occupant vehicles 10 and 210 can be prevented from falling are stored in the ROM 72 in advance.

  In the processing after S320, first, the inclination angle θB (see FIG. 9B) of the body 111 is calculated based on the inclination angle θA of the occupant portion 11 calculated in the processing of S317 or S319 (S320). The calculation of the inclination angle θB of the body 111 based on the inclination angle θA of the occupant part 11 is a table that stores a relational expression between the inclination angle θA of the occupant part 11 and the inclination angle θB of the body 111 stored in advance in the ROM 72. (Not shown). However, the inclination angle θB of the body 111 stored in this table is set such that the inclination angle at which the body 111 can be structurally inclined is the maximum inclination angle of the body 111.

  After the inclination angle θB of the body 111 is calculated, each occupant of the occupant vehicles 10 and 210 is calculated at the calculated inclination angle θB of the body 111 based on the relative position between the occupant vehicle 210 and the body vehicle 110 detected in the process of S312. It is determined whether the contact between the part 11 and the body 111 or the possibility of contact can be avoided (S321). It should be noted that the relative inclination angle between each occupant part 11 and the body 111 is determined in advance in the ROM 72 to determine whether or not contact between each occupant part 11 of the occupant vehicles 10 and 210 and the body 111 can be avoided. When the stored relative angle between each occupant part 11 and the body 111 exceeds a predetermined relative inclination angle, that is, when the distance between each occupant part 11 and the body 111 is equal to or less than the predetermined distance, each occupant part 11 and the body 111 are Judge that there is a risk of contact or contact.

  As a result of the process of S321, when it is determined that the contact between the occupant parts 11 of the occupant vehicles 10 and 210 and the body 111 can be avoided (S321: Yes), the process proceeds to S323 and subsequent processes. When it is determined that the contact between the occupant parts 11 of the occupant vehicles 10 and 210 and the body 111 cannot be avoided (S321: No), the occupant vehicle 210 and the body vehicle 110 detected in the process of S312. Based on the relative position, the inclination angle θB of the body 111 is recalculated (S322), and the process proceeds to S323 and subsequent steps. The recalculation of the inclination angle θB of the body 111 based on the relative position between the occupant vehicle 210 and the body vehicle 110 is performed by calculating a correction coefficient corresponding to the relative distance between the occupant vehicle 210 and the body vehicle 110 stored in advance in the ROM 72. This is performed by multiplying the inclination angle θB of the body 111 calculated in the process of S320 by a correction coefficient using a stored table (not shown).

  In the processing after S323, first, the information communication device 54 uses the information communication device 54 to determine the rotation speed of the L motor 52L and the R motor 52R calculated in the processing of S316 and the inclination angle θA of the occupant portion 11 calculated in the processing of S317 or S319. 210, and the rotational speed of the L motor 152L and the R motor 152R calculated in the process of S316 and the inclination angle θB of the body 111 calculated in the process of S320 or S322 are transmitted to the body vehicle 110 by the information communication device 54. Transmit (S323). Next, based on the rotation speeds of the L motor 52L and the R motor 52R calculated in the process of S316, drive control (rotation speed control) of the rotation drive device 52 (L motor 52L and R motor 52R) is performed (S324). Based on the inclination angle θA of the occupant portion 11 calculated in the process of S317 or S319, the actuator device 53 (F actuator 53F and B actuator 53B) is driven (expansion / contraction amount control) (S325). The process ends.

  Next, turning control processing of the passenger vehicle 210 will be described with reference to FIG. In the occupant vehicle 210, first, the information communication device 54 determines whether or not the rotation speed of the L motor 52L and the R motor 52R and the inclination angle θA of the occupant portion 11 are received from the occupant vehicle 10 (S331). As a result, when it is determined that the information has not been received (S331: No), the turning control process ends.

  On the other hand, if it is determined in step S331 that it has been received (S331: Yes), then, based on the rotational speeds of the L motor 52L and the R motor 52R received in step S331, the rotational drive device 52 (L The drive control (rotation speed control) of the motor 52L and the R motor 52R is performed (S332), and the actuator device 53 (the F actuator 53F and the B actuator is based on the inclination angle θA of the occupant 11 received in the process of S331). 53B) is performed (expansion / contraction amount control) (S333), and the turning control process is terminated.

  Next, turning control processing of the body vehicle 110 will be described with reference to FIG. In the third embodiment, first, the information communication device 154 determines whether or not the rotation speeds of the L motor 152L and the R motor 152R and the inclination angle θB of the body 111 are received from the passenger vehicle 10 (S341). . As a result, when it is determined that the information has not been received (S341: No), the turning control process is terminated.

  On the other hand, if it is determined in step S341 that it has been received (S341: Yes), then, based on the rotational speeds of the L motor 152L and the R motor 152R received in step S341, the rotational drive device 152 (L Drive control (rotational speed control) of the motor 152L and the R motor 152R is performed (S342), and the body deformation device 153 (C actuator 153C) is driven based on the inclination angle θB of the body 111 received in the process of S341. Control (control of expansion / contraction amount) is performed (S343), and this turning control process is terminated.

  Next, a fourth embodiment will be described with reference to FIGS.

  The linking vehicle 300 includes two occupant vehicles 310, and the two occupant vehicles 310 are linked to each other. When turning, the occupant portions 11 of the two occupant vehicles 310 are inclined toward the turning inner wheel side, respectively.

In addition, as shown to Fig.21 (a), the through-holes 341a1 and 341a2 drilled by the link support part 341a are the parts pivotally supported by the upper link 31 and the lower link 32, respectively.

  As shown in FIGS. 21 (c) and 21 (d), the second member 342 has a seat support portion 342a formed from a steel material in a substantially U shape in front view, and a substantially rectangular shape in front view from the steel material. The hollow portion 342b is formed, and one end of the hollow portion 342b is connected to the substantially bottom center portion (see FIG. 21D) of the seat support portion 342a. Further, as shown in FIG. 21C, a through hole 342b1 is formed in the hollow portion 342b. In addition, the 2nd member 342 is slidably supported by the 1st member 341 by inserting the T-shaped part 341b of the 1st member 341 mentioned above in the hollow part 342b (refer FIG. 20).

  According to this occupant support member 340, the first member 341 is rotatably supported at the substantially central part of the upper link 31 and the lower link 32, so that the occupant part 11 is accompanied by the inclination of the wheel support device 30. Can be inclined (see FIG. 25A).

  As shown in FIG. 20, a UD actuator 58UD is disposed on the front side (arrow F side) of the occupant support member 340. As described above, the UD actuator 58UD is a driving device for applying a driving force to the first member 341 and the second member 342 of the occupant support member 340 to raise and lower the occupant 11, and both ends of the UD actuator 58UD are occupant portions.

  Next, processing executed by the control device 370 of the passenger vehicle 310 will be described with reference to FIGS. First, with reference to FIG. 22, the turning control process of the passenger vehicle 310 will be described. FIG. 22 is a flowchart showing a turn control process executed by the control device 370 of the passenger vehicle 310 according to the fourth embodiment.

  The turning control process shown in FIG. 22 is a process repeatedly executed by the CPU 71 (for example, at intervals of 0.2 ms) while the power of the control device 370 is turned on. In relation to the turning control process, the CPU 71 first determines whether or not to perform the lead travel as the lead vehicle in the linked travel with the other vehicle, that is, whether or not the travel switch 50 is turned on (S411). As a result, when it is determined that the travel changeover switch 50 is turned on (S411: Yes), it means that the initiative traveling as the initiative vehicle is performed in the association traveling with the other vehicle. Is executed (S412), and the turning control process is terminated.

  On the other hand, when it is determined that the travel changeover switch 50 is not turned on, that is, is turned off (S411: No), the initiative traveling as the initiative vehicle is not performed in the associated traveling with the other vehicle. Since it is to perform the dependent traveling as the dependent vehicle, the dependent turning control process is executed (S413), and the turning control process is ended.

  Next, with reference to FIG. 23, the initiative turning control process of the passenger vehicle 310 will be described. FIG. 23 is a flowchart showing a lead turning control process executed by the control device 370 of the passenger vehicle 310 according to the fourth embodiment. Here, the description of FIG. 23 will be made with reference to FIG. 25 as appropriate. FIG. 25A is a front view of the linkage vehicle 300 and shows a state in which the vehicle is turning left. FIG. 25B is a front view of a conventional linkage vehicle, and shows a state of turning left as in FIG. That is, both FIG. 25A and FIG. 25B show a state where the vehicle is traveling forward toward the front side of the paper and turning toward the right side of the paper. In FIG. 25, only the main components are denoted by reference numerals for easy understanding.

  In the initiative turn control process (S412) shown in FIG. 23, as described above, in the process of S411 in the turn control process shown in FIG. In this case (S411: Yes), the process is executed. Regarding the initiative turning control process (S412), the CPU 71 first determines whether or not there is a turning instruction from the occupant P, that is, whether or not the joystick device 51 (operation lever) is operated in the left-right direction (S421). . As a result, when it is determined that the joystick device 51 is not operated in the left-right direction (S421: No), this means that there is no turning instruction by the occupant P, and thus this initiative turning control process is terminated. Note that the operation of the joystick device 51 in the left-right direction is detected by the left-right sensor 51b as described above.

  On the other hand, in the process of S421, when it is determined that the joystick device 51 is operated in the left-right direction (S421: Yes), it means that there is a turning instruction from the occupant P, so the joystick device 51 ( The operation state (operation amount) in the front / rear direction of the operation lever) and the operation state (operation amount) in the left / right direction are detected by the front / rear sensor 51a and the left / right sensor 51b (S422, S423), and the process proceeds to S424 and subsequent steps. .

  In the processing after S424, first, based on the operation state (operation amount) in the front-rear direction and the operation state (operation amount) in the left-right direction of the joystick device 51 (operation lever) detected in the processing of S422 and S423, The rotational speeds of the L motor 52L and the R motor 52R are calculated (S424). That is, the rotation speeds of the L motor 52L and the R motor 52R are calculated so that the occupant vehicle 310 can travel in the traveling direction and the traveling speed corresponding to the operation state of the joystick device 51 in the front-rear direction. The differential between the L motor 52L and the R motor 52R (the difference in the number of revolutions of the left and right wheels 12L and 12R) is calculated so that the occupant vehicle 310 can turn with the turning direction and turning radius corresponding to the operation state in the direction. In the present embodiment, the calculated rotation speeds of the L motor 52L and the R motor 52R are equal to the rotation speeds of the L motor 52L and the R motor 52R of another vehicle that performs the dependent traveling as the dependent vehicle in the linked traveling. It is comprised so that. However, it may be calculated individually.

  Next, the occupant vehicle 310 is turned based on the operation state (operation amount) in the front-rear direction and the operation state (operation amount) in the left-right direction of the joystick device 51 (operation lever) detected in the processes of S422 and S423. The centrifugal force generated in this case is calculated, and the inclination angle θA (see FIG. 5B) toward the turning inner wheel of the occupant portion 11 that balances the centrifugal force is calculated (S425). Note that a formula for calculating the centrifugal force generated in the occupant vehicle 310 and a formula for calculating the inclination angle θA of the occupant section 11 are stored in advance in the ROM 72 (not shown). Further, in the present embodiment, the calculated inclination angle θA of the occupant portion 11 and the inclination angle of the occupant portion 11 of the other vehicle that performs the dependent traveling as the dependent vehicle in the linked traveling to the turning inner wheel side have the same value. It is configured as follows. However, it may be calculated individually.

  After calculating the inclination angle θA of the occupant 11, whether or not the calculated inclination angle θA is a value within an allowable range, that is, an inclination angle that allows the wheel support device 30 to be structurally inclined, and Then, it is determined whether or not the occupant vehicle 310 has an inclination angle that does not fall inside the turn (S426). If the calculated inclination angle θA is a value within the allowable range (S426: Yes), the process proceeds to S428, but the calculated inclination angle θA exceeds the inclination angle that can be inclined due to the structure of the wheel support device 30. If the vehicle has a tilt angle that causes the occupant vehicle 310 to fall (S426: No), the tilt angle θA of the occupant portion 11 can be tilted by the structure of the wheel support device 30 or the occupant vehicle 310 can be tilted. After recalculating the limit inclination angle that can be avoided (S427), the process proceeds to S428 and subsequent steps. Note that the tilt angle that can be tilted due to the structure of the wheel support device 30 and the limit tilt angle at which the passenger vehicle 310 can be prevented from falling are stored in advance in the ROM 72 (not shown).

  In the processing after S428, first, the relative position with respect to another vehicle is detected by the position information detection device 55 (S428). Next, based on the inclination angle θA of the occupant unit 11 calculated in the process of S425 or S427 and the relative position with respect to the other vehicle detected in the process of S428, the lift amount L of the occupant unit 11 (see FIG. 25B). ) Is calculated (S429). It should be noted that the calculation formula for the lift amount L of the occupant section 11 is stored in advance in the ROM 72 (not shown).

  After calculating the raising / lowering amount L of the occupant section 11, the rotation speed of the L motor 52L and the R motor 52R calculated in the process of S424, the inclination angle θA of the occupant section 11 calculated in the process of S425 or S427, and S429 The lift amount L of the occupant unit 11 calculated in the process is transmitted to the other vehicle that performs the dependent traveling as the dependent vehicle in the linked traveling by the information communication device 54 (S430). Next, based on the rotation speeds of the L motor 52L and the R motor 52R calculated in the process of S424, drive control (rotation speed control) of the rotation drive device 52 (L motor 52L and R motor 52R) is performed (S431). Based on the inclination angle θA of the occupant section 11 calculated in the process of S425 or S427, drive control (control of the expansion / contraction amount) of the actuator device 53 (F actuator 53F and B actuator 53B) is performed (S432), and this leading turning The control process ends.

  As a result, the left and right wheels 12L and 12R can be differentiated, and as shown in FIG. 25A, camber angles are given to the left and right wheels 12L and 12R, and the left and right wheels 12L and 12R are camber thrust. Therefore, the occupant vehicle 310 can be turned based on the turning instruction from the occupant P.

  Further, in this case, the occupant support member 340 coupled to the occupant unit 11 is moved to the left and right wheels 12L and 12R simultaneously with the inclination of the left and right wheels 12L and 12R as the wheel support device 30 is inclined. It can be inclined in the same direction. As a result, as shown in FIG. 25 (a), the occupant portion 11 can be tilted toward the turning inner wheel and the center of gravity of the occupant vehicle 310 can be moved toward the turning inner wheel. The counter force against the arrow A) can be increased, and lifting of the turning inner wheel (the left wheel 12L in FIG. 25A) can be prevented. As a result, the turning performance of the passenger vehicle 310 can be improved.

  Next, with reference to FIG. 24, the dependent turning control process executed by the control device 370 of the passenger vehicle 310 will be described. FIG. 24 is a flowchart showing a dependent turning control process executed by the control device 370 of the passenger vehicle 310 in the fourth embodiment. Here, the description of FIG. 24 will be made with reference to FIG. 25 as appropriate, similarly to the description of FIG.

  As described above, the dependent turning control process (S413) shown in FIG. 24 does not perform the lead running as the leading vehicle in the linked running with the other vehicle in the process of S411 of the turning control process shown in FIG. This process is executed when it is determined that the subordinate vehicle is to be subordinated (S411: No). Regarding the dependent turning control process (S413), the CPU 71 first uses the information communication device 54 to determine the rotation speed of the L motor 52L and the R motor 52R, the inclination angle θA of the occupant portion 11, and the lift amount L of the occupant portion 11. It is determined whether or not it has been received from another vehicle that performs the initiative run as the lead vehicle in the linked running (S441). As a result, when it is determined that the information has not been received (S441: No), this dependent turning control process is terminated.

  On the other hand, if it is determined that the signal has been received in the process of S441 (S441: Yes), then, based on the rotational speeds of the L motor 52L and the R motor 52R received in the process of S441, the rotational drive device 52 (L Drive control (rotational speed control) of the motor 52L and the R motor 52) is performed (S442). Thereafter, based on the inclination angle θA of the occupant section 11 received in the process of S441, the actuator device 53 (F actuator 53F and B actuator 53B) is driven (expansion / contraction amount control) (S443), and the process of S441 is performed. On the basis of the lift amount L of the occupant unit 11 received in (5), drive control (control of expansion / contraction amount) of the occupant lift device 58 (UD actuator 58UD) is performed (S444), and this dependent turning control process is terminated.

  As a result, the left and right wheels 12L and 12R can be differentiated, and as shown in FIG. 25A, camber angles are given to the left and right wheels 12L and 12R, and the left and right wheels 12L and 12R are camber thrust. Therefore, the occupant vehicle 310 can be turned based on the turning instruction from the occupant P.

  Further, in this case, the occupant support member 340 coupled to the occupant unit 11 is moved to the left and right wheels 12L and 12R simultaneously with the inclination of the left and right wheels 12L and 12R as the wheel support device 30 is inclined. It can be inclined in the same direction. As a result, as shown in FIG. 25 (a), the occupant portion 11 can be tilted toward the turning inner wheel and the center of gravity of the occupant vehicle 310 can be moved toward the turning inner wheel. The counter force against the arrow A) can be increased, and lifting of the turning inner wheel (the left wheel 12L in FIG. 25A) can be prevented. As a result, the turning performance of the passenger vehicle 310 can be improved.

  As described above, according to the passenger vehicle 310 in the present embodiment, as shown in FIG. 25A, the relative height positions of the passenger portions 11 of the two passenger vehicles 310, that is, the passenger P , Ps can be made to coincide with each other in the height position of each seat 11a (sitting surface view 11a1). Therefore, even when two occupant vehicles 310 that turn while tilting the occupant portion 11 toward the turning inner wheel side in order to improve turning performance, the occupant P that is located inside the turning is located outside the turning The discomfort to the passengers P and Ps, such as the appearance of looking down at the occupant Ps, or the appearance of the occupant Ps located outside the turn having to look up at the occupant P located inside the turn, is eliminated (FIG. 25). (See (a)), the comfort of the passengers P and Ps can be improved.

  In addition, the occupant vehicle 310 that performs the dependent traveling as the dependent vehicle in the coordinated traveling can change the occupant unit 11 in accordance with the turning information received by the information communication device 54 (in the present embodiment, the lift L of the occupant unit 11). Since it raises / lowers, while raising / lowering of the passenger | crew part 11 can be performed synchronizing with the inclination of the passenger | crew part 11, the synchronization precision with the raising / lowering of this passenger | crew part 11 and the inclination of the passenger | crew part 11 is securable.

  In addition, since the occupant vehicle 310 that performs the lead travel as the lead vehicle in the linked travel is configured to calculate the lift L of the occupant portion 11 of the passenger vehicle 310 that performs the slave travel as the slave vehicle, The occupant vehicle 310 that performs the dependent travel of the vehicle only receives the lift amount L of the occupant part 11 by the information communication device 54, and does not need to calculate the lift amount L of the occupant part 11 by itself. 58UD) can be driven and controlled. Accordingly, the control burden can be reduced accordingly.

  Furthermore, the occupant vehicle 310 that performs the dependent traveling as the dependent vehicle in the coordinated traveling, the relative position with respect to the other vehicle detected by the position information detecting device 55, and the turning information received by the information communication device 54 (in this embodiment, Since the occupant unit 11 is moved up and down according to the lift amount L) of the occupant unit 11, the occupant unit 11 can be moved up and down by the lift amount L according to the relative position of the two occupant vehicles 310. The relative height positions of the occupant portions 11 of the occupant vehicle 310 can be matched with high accuracy.

  Next, a fifth embodiment will be described with reference to FIGS. 26 and 27. FIG. FIG. 26 is a flowchart showing a lead turning control process executed by the control device 370 of the occupant vehicle 310 according to the fifth embodiment, and FIG. 27 is executed by the control device 370 of the occupant vehicle 310 according to the fifth embodiment. It is a flowchart which shows the dependent turning control process performed.

  In the fourth embodiment, a case has been described in which the occupant vehicle 310 that performs the lead travel as the lead vehicle in the linked travel calculates the lift L of the occupant portion 11 of the passenger vehicle 310 that performs the slave travel as the subordinate vehicle. In the fifth embodiment, an occupant vehicle 310 that performs subordinate travel as a subordinate vehicle in linked travel calculates the lift amount L of the occupant unit 11 itself. In addition, the same code | symbol is attached | subjected to the part same as 4th Embodiment, and the description is abbreviate | omitted.

  First, with reference to FIG. 26, the initiative turning control process of the passenger vehicle 310 will be described. In the fifth embodiment, after the processing of S426 or S427 is executed, the processing after S528 is executed.

  In the processing after S528, first, the information communication device 54 indicates the operation state (operation amount) in the front-rear direction and the operation state (operation amount) in the left-right direction of the joystick device 51 (operation lever) detected in the processing of S422 and S423. Is transmitted to the other vehicle performing the dependent traveling as the dependent vehicle in the linked traveling (S528).

  Next, based on the rotation speeds of the L motor 52L and the R motor 52R calculated in the process of S424, drive control (rotation speed control) of the rotation drive device 52 (L motor 52L and R motor 52R) is performed (S529). Based on the inclination angle θA of the occupant portion 11 calculated in the process of S425 or S427, drive control (control of the expansion / contraction amount) of the actuator device 53 (F actuator 53F and B actuator 53B) is performed (S530). The control process ends.

  Next, with reference to FIG. 27, the dependent turning control process of the passenger vehicle 310 will be described. In the fifth embodiment, first of all, the information communication device 54 uses the joystick device 51 (operation lever) to operate in the front-rear direction (operation amount) and the operation state in the left-right direction (operation amount). It is judged whether it received from the other vehicle which performs a leading run as (S541). As a result, when it is determined that the information has not been received (S541: No), this dependent turning control process is terminated.

  On the other hand, if it is determined in S541 that it has been received (S541: Yes), then the operation state (operation amount) in the front-rear direction of the joystick device 51 (operation lever) received in S541 and the left and right Based on the operation state (operation amount) in the direction, the rotation speeds of the L motor 52L and the R motor 52R are calculated (S542). That is, the rotation speeds of the L motor 52L and the R motor 52R are calculated so that the occupant vehicle 310 can travel in the traveling direction and the traveling speed corresponding to the operation state of the joystick device 51 in the front-rear direction. The differential between the L motor 52L and the R motor 52R (the difference in the number of revolutions of the left and right wheels 12L and 12R) is calculated so that the occupant vehicle 310 can turn with the turning direction and turning radius corresponding to the operation state in the direction.

  Next, when the occupant vehicle 310 is turned based on the operation state (operation amount) in the front-rear direction and the operation state (operation amount) in the left-right direction of the joystick device 51 (operation lever) received in the process of S541 Is calculated, and an inclination angle θA (refer to FIG. 5B) of the occupant portion 11 toward the turning inner wheel that is balanced with the centrifugal force is calculated (S543). Note that a formula for calculating the centrifugal force generated in the occupant vehicle 310 and a formula for calculating the inclination angle θA of the occupant section 11 are stored in advance in the ROM 72 (not shown).

  After calculating the inclination angle θA of the occupant 11, whether or not the calculated inclination angle θA is a value within an allowable range, that is, an inclination angle that allows the wheel support device 30 to be structurally inclined, and Then, it is determined whether or not the occupant vehicle 310 has an inclination angle that does not fall inside the turn (S544). If the calculated tilt angle θA is within the allowable range (S544: Yes), the process proceeds to S546. However, the calculated tilt angle θA exceeds the tilt angle at which the wheel support device 30 can tilt because of the structure of the wheel support device 30. If the vehicle has a tilt angle that causes the occupant vehicle 310 to fall (S544: No), the tilt angle θA of the occupant portion 11 can be tilted by the structure of the wheel support device 30 or the occupant vehicle 310 can be tilted. After recalculating the limit inclination angle that can be avoided (S545), the process proceeds to S546 and subsequent steps. Note that the tilt angle that can be tilted due to the structure of the wheel support device 30 and the limit tilt angle at which the passenger vehicle 310 can be prevented from falling are stored in advance in the ROM 72 (not shown).

  In the processing after S546, first, the relative position with respect to another vehicle is detected by the position information detection device 55 (S546). Next, according to the inclination angle θA of the occupant section 11 calculated in the process of S543 or S545 and the relative position with respect to the other vehicle detected in the process of S546, the lift amount L of the occupant section 11 (see FIG. 25B). ) Is calculated (S547). It should be noted that the calculation formula for the lift amount L of the occupant section 11 is stored in advance in the ROM 72 (not shown).

  After calculating the raising / lowering amount L of the occupant 11, the drive control of the rotation drive device 52 (L motor 52L and R motor 52R) is performed based on the rotation speeds of the L motor 52L and R motor 52R calculated in the processing of S542 ( (Rotational speed control) is performed (S548). Next, based on the inclination angle θA of the occupant portion 11 calculated in the processing of S543 or S545, drive control (control of expansion / contraction amount) of the actuator device 53 (F actuator 53F and B actuator 53B) is performed (S549), and S547. Based on the lift amount L of the occupant unit 11 calculated by the above process, drive control (control of the expansion / contraction amount) of the occupant unit lifting device 58 (UD actuator 58UD) is performed (S550), and this dependent turning control process is terminated.

  As described above, according to the occupant vehicle 310 in the present embodiment, the occupant vehicle 310 that performs the dependent traveling as the dependent vehicle in the linked traveling is configured to calculate the elevation amount L of the occupant unit 11 by itself. Therefore, it is possible to share the control burden with the occupant vehicle 310 that performs the lead running as the lead vehicle, and to suppress the time lag between the raising and lowering of the occupant part 11 and the inclination of the occupant part 11.

In this case, when turning, the inclination angle θA of the occupant part 11, the inclination angle θB of the body 111, or the elevation amount L of the occupant part 11 is calculated from the inclination angle actually acting on the occupant part 11 by centrifugal force. Therefore, the inclination angle θA of the occupant portion 11 and the inclination angle θB of the body 111 that are balanced with the centrifugal force can be calculated with high accuracy. As a result, the elevation amount L of the occupant portion 11 can be calculated with high accuracy. it can.

However, the present invention is not necessarily limited to this. For example, the occupant unit 11 of the occupant vehicle 310 that performs the initiative run as the initiative vehicle may be lifted or lowered relative to the other vehicle detected by the position information detection device 55. From the position, the occupant portion 11 of any of the occupant vehicles 310 located inside or outside the turn may be lifted or lowered.

  Moreover, although the said 4th and 5th embodiment demonstrated the case where the passenger | crew part 11 of any one of the two passenger vehicles 310 which carry out linked traveling was raised / lowered, it is not necessarily restricted to this. Instead, the occupant portions 11 of the two occupant vehicles 310 may be raised and lowered. In this case, the occupant portions 11 of the two occupant vehicles 310 are raised and lowered in opposite directions, that is, the occupant portions 11 of the occupant vehicle 310 located on the outer side of the turn are raised, while the occupants located on the inner side of the turn. By lowering the occupant part 11 of the vehicle 310, the amount of elevation of the occupant part 11 of the occupant vehicle 310 located on the outer side of the turn can be suppressed. The turning performance of the occupant vehicle 310 can be improved. In addition, the raising / lowering amount of the passenger | crew part 11 of each passenger vehicle 310 is not necessarily restricted to the ratio of 1: 1, and may be the ratio of 1: 2 or 1: 3.

  Moreover, although the said 4th and 5th embodiment demonstrated the case where the height of each seat 11a (seat surface part 11a1) where each passenger | crew P, Ps seated corresponded, it is not necessarily restricted to this. For example, a sight line position detection device that detects the height of the line of sight of each occupant P, Ps is provided, and the occupant unit 11 is configured to match the heights of the lines of sight of each occupant P, Ps detected by the line of sight position detection device. It may be raised and lowered. In this case, the height of the line of sight can be matched regardless of the difference in seating height between the passengers P and Ps, so that further improvement in comfort can be realized.
