Hereinafter, the configuration of the automobile 10 will be described with reference to the drawings. FIG. 1 is a perspective view of a vehicle 10 disclosed herein. 2 is a side view of the automobile 10, and FIG. 3 is a front view of the automobile 10.

The automobile 10 disclosed in the present specification is mainly used as a movable business space, and runs on a public road by automatic driving. The mode of use of the automobile 10 can be changed as appropriate, and for example, the automobile 10 may be used as a store such as a retail store that displays and sells various products or a restaurant that provides food and drink. Further, as another form, the automobile 10 may be used as an office for office work, meetings with customers, and the like. Further, the automobile 10 may be used as a taxi, a bus, or a transportation vehicle that transports customers or luggage. Further, the usage scene of the automobile 10 is not limited to business, and for example, the automobile 10 may be used as an individual transportation means.

The automobile 10 is equipped with a large number of sensors for detecting the external environment, and automatically travels on a public road based on the information detected by these sensors. The automobile 10 is also equipped with a communication device for communicating with another communication device (for example, a communication terminal mounted on the other car 10 or a mobile terminal owned by a customer). Although various modes of operation of the automobile 10 are conceivable, for example, the automobile 10 notifies the customer of location information of the automobile 10 and business content (store name, list of products handled, etc.) via a communication device. To be done. The customer notifies the automobile 10 of the location information of the customer and the request of the customer (request for delivery service, request for moving shop, etc.) via the communication device. Then, the occupant of the vehicle 10 that has received the request from the customer executes the process according to the request.

Next, the configuration of the automobile 10 will be described. As shown in FIG. 1, the automobile 10 does not have a hood or a trunk, but has a substantially box-shaped body in which a front end face and a rear end face stand up substantially vertically. At the four corners of the automobile 10, two wheels are provided, two wheels in total, for a total of eight wheels. More specifically, the vehicle 10 includes a pair of first front wheels 12f1 arranged near the front end and at both ends in the width direction, a pair of second front wheels 12f2 arranged adjacent to the rear of the first front wheel 12f1, and a rear side. It has a pair of first rear wheels 12r1 arranged near the ends and at both ends in the width direction, and a pair of second rear wheels 12r2 arranged adjacent to the front of the first rear wheel 12r1. In the following, when the first and the second are not distinguished, the numbers after the alphabets f and r are omitted and are referred to as “front wheel 12f” and “rear wheel 12r”. When the front wheels and the rear wheels are not distinguished, they are collectively called "wheel 12".

As described above, the vehicle 10 having the eight-wheel configuration can reduce the load applied to one wheel 12 and can reduce the diameter of each wheel 12 as compared with the four-wheel configuration. Since the wheel 12 has a small diameter, the floor level of the vehicle interior can be lowered and the vehicle interior space can be secured wide. Further, since the wheel 12 has a small diameter, it is possible to secure a wide display area of the display unit 16 described later, which will be described later.

A front display portion 16f, a rear display portion 16r, and a side display portion 16s for displaying images are provided on the exterior surfaces of the front portion, the rear portion, and the side portions of the body. In the following, the subscript alphabets will be omitted and will be referred to as the "display unit 16" if the front, rear, and side are not distinguished. In FIG. 1 to FIG. 3, a portion hatched with thin black ink indicates a range that functions as the display unit 16. The video displayed on the display unit 16 is not particularly limited, but for example, a video for advertising/promotion of a product/service can be displayed. The video for advertisement/promotion includes, for example, the name of a store operated by the automobile 10 and an image of a handled product. Further, the display unit 16 may display information indicating the driving status of the automobile 10 (for example, information indicating the traveling direction or the course changing direction), a message to the surroundings, and the like.

Each display unit 16 is composed of one or more displays. Examples of the display that constitutes the display unit 16 include a liquid crystal display and an organic EL display. The display constituting these display units 16 may be an opaque display that does not transmit light, or may be a transparent display that transmits light when an image is not displayed.

Here, when an opaque display is arranged on the front part, the rear part, and the side part of the body, it is not possible to provide a window for visually recognizing the external environment. However, the automobile 10 disclosed in the present specification travels in the automatic driving mode as described above. Therefore, since it is not necessary for the occupant to visually recognize the external environment, there is no problem even if most of the exterior surface of the body is covered with the opaque display. However, there may be a request to visually recognize the external environment for a reason other than driving. In that case, a display may be arranged in the vehicle compartment, and an image outside the vehicle captured by an optical camera or the like attached for automatic driving may be displayed on the vehicle interior display.

As another form, a transparent display may be used, and in this case, the transparent display may be used as a window glass of the automobile 10. That is, an opening that functions as a window may be formed in the body of the automobile 10, and a transparent display may be fitted into this opening. In this case, the transparency of the window glass can be adjusted by adjusting the display range and density of the image on the transparent display. In other words, the transparent display can be used as a smoke window with variable density.

Further, in this example, the size of the display unit 16 is made larger than the size of the automobile 10 in order to further improve the advertising effect and the effect of calling attention by the display unit 16. In particular, the side display portion 16s that is easily visible from the outside of the vehicle has a size that occupies most of the side portion of the automobile 10. Specifically, as shown in FIG. 1, the side display portion 16s arranged on the side portion of the automobile 10 extends in the vertical direction from the vicinity of the upper end of the body to a position below the top of the wheel 12. ing. Further, the side display portion 16s extends to the outside from the rear end of the first front wheel 12f1 and the front end of the first rear wheel 12r1 (that is, the front-rear inner side end of the wheel 12) in the front-rear direction. As a result, the front-rear end of the lower edge of the side display portion 16 is curved or bent upward so as to avoid the wheel 12. Furthermore, in other words, the side display portion 16s has a size and shape such that the lower two corners thereof are notched so as to avoid the wheel 12 but spread beyond the wheel 12. Has become. In this way, the side display portion 16s has a size and shape that spreads beyond the wheel 12 while avoiding the wheel 12 to obtain the side display portion 16s larger than the size of the automobile 10. be able to. As a result, it is possible to further improve the effect of advertising and alerting the side display unit 16s.

Further, in this example, the front display portion 16f and the rear display portion 16r arranged in the front and rear portions of the automobile 10 are also made as large as possible. Specifically, as shown in FIG. 3, the lower ends of the front display portion 16f and the rear display portion 16r are located below the top of the wheel 12. Further, the upper ends of the front and rear portions of the automobile 10 are inclined toward the roof, but the front/rear display portions 16f and 16r extend to this inclined surface.

Such an automobile 10 is configured by combining a plurality of units 14e and 14i. FIG. 4 is a diagram in which one automobile 10 is divided into units 14e and 14i. The vehicle 10 of this example includes a pair of end units 14e and a plurality of intermediate units 14i arranged between the pair of end units 14e. In the following, when the end portion and the middle portion are not distinguished, they are simply referred to as "unit 14". The end unit 14e is a unit that functions as a front portion (front end unit) or a rear portion (rear end unit) of the automobile 10. That is, in the automobile 10 of this example, the front portion (front end unit) and the rear portion (rear end unit) have exactly the same configuration. Each end unit 14e has four wheels 12 that function as a rear wheel 12r or a front wheel 12f. A display 18 arranged so as to avoid the wheels 12 is arranged on the side of the end unit 14e. One end of the end unit 14e in the front-rear direction is closed and constitutes a front end surface or a rear end surface of the vehicle. The other end of the end unit 14e in the front-rear direction has a large opening so that it can communicate with the internal space of the intermediate unit 14i. In this example, the front part and the rear part of the vehicle have the same configuration, but they may have different configurations. Instead of the pair of end units 14e having the same configuration, a front unit and a rear unit having different configurations may be used.

The intermediate unit 14i is a substantially rectangular tube-shaped unit 14 having large openings at both ends in the front-rear direction. The intermediate unit 14i has a container-type upper that constitutes a part of the vehicle interior, and an underfloor battery that is arranged below the container-type upper (that is, below the vehicle interior floor panel). In addition, a side opening of the container-type upper is provided with a boarding/alighting opening 24 serving as a boarding/alighting opening and a door 22 for opening/closing the boarding/alighting opening 24 (see FIG. 7 ). The display 18 constituting the side display unit 16s described above is arranged on almost the entire exterior surface of the door 22. Further, the boarding/alighting opening 24 extends over the entire width of the intermediate unit 14i in the front-rear direction. Therefore, when the door 22 is opened, one large entry/exit opening 24 without pillars or the like is obtained on the side portion of the automobile 10 as shown in FIG. 7.

As shown in FIG. 7, when the entry/exit opening 24 is made pillarless, the entry/exit opening 24 is provided only on one side of the vehicle 10 on the opposite side in order to secure the strength of the body. It is desirable not to provide the boarding/alighting opening 24 on the side portion. Of course, if a frame such as a pillar is provided in the passenger compartment 24 or the passenger compartment, the passenger compartment 24 may be provided on both sides of the vehicle 10.

The intermediate unit 14i can be mechanically and electrically connected to the end unit 14e or another intermediate unit 14i. The form of this connection is not particularly limited, and for example, the end face of each unit 14 may be provided with a connection mechanism capable of being mechanically connected to the end face of another unit 14. As another form, each unit 14 may be mechanically connected using a connecting member (for example, a connecting hood) provided separately from the unit 14. Moreover, each unit 14 may be electrically connected using various connectors. Therefore, the plurality of displays 18 forming the side display unit 16s are also electrically connected so as to function as one screen linked with each other. Such connection of the units 14 may be performed at a production site such as a factory, or may be performed at a premises owned by an automobile dealer or the owner of the automobile 10.

The number of intermediate units 14i arranged in one automobile 10 is not particularly limited and may be changed as appropriate. For example, the automobile 10 may have a “middle” configuration in which two intermediate units 14i are arranged between two end units 14e. Alternatively, as shown in FIG. 5, the vehicle 10 may have a “short” structure having one intermediate unit 14i, or, as shown in FIG. 6, a “long” structure having four intermediate units 14i. It may be configured. Further, so far, only two types of the end unit 14e and the intermediate unit 14i forming the pillarless entry/exit opening 24 are combined, but if necessary, three or more types of units 14 may be combined. Good. For example, in addition to or instead of the intermediate unit 14i described above, a unit provided in the middle of the pair of end units 14e and provided with the wheels 12 or a pillar is provided in the entry/exit opening 24. Units and the like may be combined.

As described above, the door 22 is provided on the side portion of the intermediate unit 14i, but the form of the door 22 is not particularly limited as long as the opening/closing opening 24 can be completely opened. Therefore, for example, the door 22 provided in the intermediate unit 14i may be a slide door. As shown in FIG. 7, the slidably moved door 22 is located on the side of the end unit 14e so as to cover the side of the end unit 14e. Further, when the door is opened, two or more slide doors may be stacked in the thickness direction. In this way, by stacking two or more slide doors in the thickness direction, all the doors 22 can be arranged on the side of the end unit 14e, and the entry/exit opening 24 can be widened.

When the door 22 is a slide door, a guide mechanism for guiding the slide of the door 22 is provided. Although various configurations of the guide mechanism are conceivable, for example, the slide mechanism of the door 22 may be configured using the guide rail 30 and the slide roller 32. FIG. 8 is a diagram showing an example of the slide mechanism, and is a schematic vertical cross section of the periphery of the lower portion of the automobile 10. In FIG. 8, the right side of the drawing is the outer side in the vehicle width direction, and the upper side of the drawing is the upper side of the vehicle.

In the example of FIG. 8, a slide roller 32 is provided below the door 22. Further, the battery mounting surface 34 is provided with a guide rail 30 for guiding the moving direction of the slide roller 32. That is, the underfloor battery 36 is provided below the floor panel 38, but there is a slight space between the floor panel 38 and the mounting surface 34 of the underfloor battery 36. The guide rail 30 is provided in this space. Further, similar slide rollers 32 and guide rails 30 are also provided on the upper portion of the door 22 and the upper portion of the automobile 10.

FIG. 9 is a view of the guide rail 30 placed on the battery mounting surface 34 as seen from above, showing how the door 22 slides. In FIG. 9, the lower side of the drawing is the outer side in the vehicle width direction, and the left side of the drawing is the front-rear direction end side. Further, the guide rail 30 shown in FIG. 9 is a guide rail 30 for sliding two doors 22, which are continuously arranged in the front-rear direction, in one direction and stacking them in the thickness direction. In the following, the door 22 closer to the front and rear ends of the two doors 22 is referred to as an "end door 22e", and the remaining doors 22 are referred to as "center doors 22c".

In this case, as shown in FIG. 9, the guide rail 30 includes three rows of slide rails 30a extending in the vehicle front-rear direction and a shift rail 30b extending in the vehicle width direction to connect the three rows of slide rails 30a. Further, the slide roller 32 provided at the lower portion of the vehicle is capable of moving along these rails 30a and 30b and turning 90 degrees. The slide roller 32 is driven by a motor or the like.

When the door 22 is opened, as shown in FIG. 9, the door 22 is slid in the vehicle front-rear direction while being shifted in the vehicle width direction as necessary. More specifically, when the door 22 is closed, as shown in FIG. 9A, the slide rollers 32 of the end door 22e and the central door 22c are both positioned on the innermost slide rail 30a. .. When opening the door 22, first, as shown in FIG. 9B, each slide roller 32 is swung 90 degrees so that it can be moved in the width direction, and then slides along the shift rail 30b. The roller 32 is moved outward by one line. Then, as shown in FIG. 9(c), each slide roller 32 is swung again so as to be movable in the front-rear direction, and then each slide roller 32 is moved along the middle slide rail 30a toward the end side. Move to. After that, when the end door 22e reaches the side of the end unit 14e, as shown in FIG. 9(d), only the slide roller 32 of the central door 22c is rotated 90 degrees and then the shift rail 30b is moved. Along which the central door 22c alone is moved outward by one row. Then, the central door 22c is slid along the outermost slide rail 30a toward the front and rear direction end side, and the opening operation of the door 22 is completed.

Note that the configuration of the door 22 described here is an example, and other configurations may be used as long as the opening/closing opening 24 can be widely opened. For example, although the door 22 is slid using the rail in the above description, the door 22 may be slid using magnetic force, for example.

Further, the door 22 is not limited to the slide door, and may be a door of another type. For example, as shown in FIG. 10, the door 22 may be a flip-up type door that flips upward by rotating around a hinge 40 provided at the upper end of the door 22. At this time, in order to reduce the pop-out amount of the door 22 that is flipped up, an additional hinge 42 that bends the door 22 into two or more may be provided at the center in the height direction of the door 22. Further, the flipped-up door 22 may be housed in the attic of the automobile 10. In any case, when the door 22 is opened, the door 22 is moved to a position where it does not overlap the boarding/alighting opening 24, so that a large opening can be obtained. It should be noted that the display 18 provided on the exterior surface of each door 22 may be turned off when the door 22 is opened or may continue to display an image while the power is on.

Here, as is clear from the above description, the automobile 10 of the present example has a pair of end units 14e (vehicle end portions) at both ends in the vehicle front-rear direction. The two end units 14e have both a function as a vehicle front part and a function as a vehicle rear part. For example, usually, a headlight is provided at the front of the vehicle and a taillight is provided at the rear of the vehicle. As shown in FIG. 3, the end unit 14e of this example is provided with a light 20 that functions as a headlight and also as a taillight. When the end unit 14e functions as the vehicle front part, the light 20 is turned on in a color (white or the like) suitable for the headlight according to the brightness of the surrounding environment, and the end unit 14e functions as the vehicle rear part. In this case, the light (or red) that is suitable for the taillight is turned on or blinks depending on the use condition of the brake.

Then, in the vehicle 10 of this example, when the traveling direction of the vehicle 10 is reversed, the rotation direction of the wheels 12 is reversed instead of making a U-turn of the vehicle 10. In conjunction with the reversal of the traveling direction of the automobile 10, the end unit 14e that functions as the vehicle front part before the reversal functions as the vehicle rear part, and the end unit 14e that functions as the vehicle rear part before the reversal advances the vehicle front part. The functions of the two end units 14e are switched so as to function as a unit. As a result, the traveling direction can be reversed without the vehicle making a U-turn.

The automobile 10 of this example is of an in-wheel motor type in which a traveling motor is arranged inside each wheel 12. Then, as shown in FIG. 11A, a wheel cover 44 is provided on the axially outer end surface of the wheel 12. The wheel cover 44 is provided with a duct for sending cooling air to the traveling motor (in-wheel motor). When reversing the traveling direction of the automobile 10, as shown in FIG. 11B, the wheel cover 44 is rotated so that the direction of the intake port 46 of this duct rotates 180 degrees. As a result, the intake port 46 always faces the front side in the traveling direction, and the traveling wind can be effectively taken into the duct. Further, the wheel cover 44 is provided with a mark 48 (for example, an arrow) indicating the traveling direction, and when the wheel cover 44 rotates, the direction of the mark 48 is also reversed by 180 degrees. And thereby, the advancing direction of the motor vehicle 10 can be more reliably notified to the surroundings. The well-known technology can be adopted for the configuration of the in-wheel motor, and therefore detailed description thereof is omitted here.

By the way, as described above, two such wheels 12 are provided, two in each of the four corners of the automobile 10, in total. In this example, when the vehicle 10 is turned largely, only the four outer wheels 12 (the first front wheel 12f1 and the first rear wheel 12r1) of the eight wheels 12 are steered. Specifically, first, as shown in FIG. 12A, first, only the first front wheel 12f1 and the first rear wheel 12r1 are lowered downward, and the second front wheel 12f2 and the second rear wheel 12r2 are floated in the air. Then, in this state, as shown in FIG. 12(b), only the first front wheel 12f1 and the first rear wheel 12r1 are turned and run. When the turning operation is completed, the first front wheel 12f1 and the first rear wheel 12r1 are raised and the eight wheels are run again.

With such a configuration, the automobile 10 can be turned on the spot, and the small turning performance can be improved. Further, since the first front wheel 12f1 and the first rear wheel 12r1 are arranged on the outer side in the vehicle front-rear direction, the vehicle can make a large turn without interfering with the floor panel 38. This will be described with reference to FIG. FIG. 13 is a diagram showing a positional relationship between the first front wheel 12f1, the second front wheel 12f2, and the floor panel 38. In FIG. 13, circles C1 and C2 indicate spaces required for turning the first front wheel 12f1 and the second front wheel 12f2, respectively.

As shown in FIG. 13, in this example, the second front wheel 12f2 is located rearward of the front end of the floor panel 38. The side edge of the second front wheel 12f2 is close to the side edge of the floor panel 38. Therefore, when trying to make a large turn of the second front wheel 12f2, the second front wheel 12f2 interferes with the floor panel 38. On the other hand, the rotation center and the turning center of the first front wheel 12f1 are located in front of the front end of the floor panel 38. Further, the front edge of the floor panel 38 has a convex arc in the front, and the width thereof becomes narrower toward the front. Therefore, even if the first front wheel 12f1 makes a large turn, interference between the first front wheel 12f1 and the floor panel is unlikely to occur.

In the above description, the first front wheel 12f1 and the first rear wheel 12r1 are turned while they are in contact with the ground, but the first front wheel 12f1 and the first rear wheel 12r1 may be turned in the air and then are in contact with the ground. .. That is, when turning, first, the second front wheel 12f2 and the second rear wheel 12r2 are lowered to float the first front wheel 12f1 and the first rear wheel 12r1 and then the first front wheel 12f1 and the first rear wheel 12r1. To turn. Then, after that, the first front wheel 12f1 and the first rear wheel 12r1 may be lowered and the second front wheel 12f2 and the second rear wheel 12r2 may be raised so that the first front wheel 12f1 and the first rear wheel 12r1 are grounded. With such a configuration, it is possible to significantly reduce the load when turning the first front wheel 12f1 and the first rear wheel 12r1.

In addition, the above description is an operation for a large turn, and when the turning amount is small, the second front wheel 12f2 and the second rear wheel 12r2 may also be turned. That is, while keeping the eight wheels 12f1, 12f2, 12r1, 12r2 in contact with the ground, the second front wheel 12f2 and the second rear wheel 12r2 are turned together with the first front wheel 12f1 and the first rear wheel 12r1 as necessary. May be.

Further, the configuration described so far is an example, and at least the display unit 16 provided on the side portion of the automobile 10 extends below the top of the wheel 12 in the vertical direction, and the front and rear of the wheel 12 in the front-back direction. Other configurations may be appropriately changed as long as they extend from the inner end in the direction to the outer side.
