DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, the embodiments of the present disclosure will be described in detail with reference to the drawings as appropriate. However, more detailed description than necessary may be omitted. For example, detailed description of already well-known matters and duplicated description of substantially the same configuration may be omitted. This is to avoid the following description becoming unnecessarily redundant and to facilitate understanding by those skilled in the art. Note that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0012] (Embodiment 1) Fig. 1 is a plan view (viewed from above) showing a configuration example of a vehicle 1 according to embodiment 1. Fig. 2 is a side view (viewed from the side) showing the configuration example of a vehicle according to embodiment 1.

[0013] For convenience of explanation, as shown in Figures 1 and 2, the overall length direction of the vehicle 1 is the Y axis, the width direction of the vehicle 1 is the X axis, and the height direction of the vehicle 1 is the Z axis. For convenience of explanation, the positive direction of the Y axis may be referred to as the "front", the negative direction of the Y axis as the "rear", the positive direction of the X axis as the "right", the negative direction of the X axis as the "left", the positive direction of the Z axis as the "up", and the negative direction of the Z axis as the "down". Note that these expressions relating to directions are used for convenience of explanation and are not intended to limit the position of the structure during actual use.

[0014] The vehicle 1 includes a vehicle body 2, a plurality of wheels (wheel group 3) connected to the vehicle body 2, a door 4 disposed on the vehicle body 2, a planar light-shielding member 5 having variable light transmittance disposed on the door 4, and an entrance / exit 6 through which people get on and off. The number of wheels may be two, three, four, five or more. The vehicle 1 can run in a predetermined direction using the wheel group 3. Examples of the vehicle 1 include passenger cars, buses, campers, trucks, etc.

[0015] The door 4 is opened in a first direction by an actuator and closed in a second direction opposite to the first direction. The door 4 is disposed on a side surface of the vehicle body 2, and the first direction may be a direction along the side surface. In this case, the door 4 may be a sliding door that opens in the first direction (e.g., the negative direction of the Y axis) and closes in the second direction (e.g., the positive direction of the Y axis) while along the side surface. However, the door 4 according to the first embodiment is not limited to a sliding door, and may be, for example, a swing door or a plug door.

[0016] 3A and 3B are diagrams for explaining the relationship between the opening operation of door 4 and the light transmittance of light blocking member 5 according to embodiment 1. FIG.

[0017] The use of light-shielding members 5 on the doors 4 has been considered for the purpose of popularizing autonomous driving, improving the efficiency of air conditioning inside the vehicle, and ensuring the privacy of passengers. However, if light-shielding members 5 are used on the doors 4, people may feel uneasy when getting off the vehicle through the doors 4 because they cannot see what is happening outside. In addition, if the entire surface of the doors 4 of the vehicle 1 is made of light-shielding members 5, people may feel inconvenienced when getting on because it is difficult to find the position of the doors 4, and may feel uneasy because they cannot see what is happening inside the vehicle.

[0018] Therefore, the vehicle 1 according to the first embodiment performs the following operation as shown in FIGS. 3A and 3B. (S11) When the vehicle 1 detects the person A standing in front of the door 4, it executes the processes from S12 onwards. (S12)-(S14) The vehicle 1 gradually makes the light blocking member 5 of the door 4 transparent in the first direction, which is the opening direction of the door 4. This allows the person A to recognize that the door 4 is about to open, and that the door 4 opens in the first direction in which it gradually becomes transparent. (S15)-(S18) After that, the vehicle 1 automatically opens the door 4 in the first direction, and the person A gets off through the entrance 6.

[0019] By the above process, person A inside the vehicle can check outside through the transparent door 4 before getting off, and can get off safely, securely, and comfortably. Also, people outside the vehicle can visually confirm through the transparent door 4 that person A is about to get off the vehicle 1. This improves the safety of people outside the vehicle.

[0020] The operations shown in FIGS. 3A and 3B will now be described in more detail.

[0021] FIG. 4 is a diagram for explaining a first example of the relationship between the opening operation of the door 4 and the change in light transmittance of the light blocking member 5 according to the first embodiment.

[0022] As shown in Fig. 4, the light blocking member 5 provided on the door 4 includes at least a first region 11 and a second region 12 divided in a first direction. Note that in Fig. 4, the dotted line between the first region 11 and the second region 12 is drawn for the sake of convenience to make the boundary between the regions easier to understand, and does not actually exist.

[0023] As shown in FIG. 4(1), when the vehicle 1 is in a first state, the first area 11 and the second area 12 of the light blocking member 5 of the door 4 have a first light transmittance.

[0024] As shown in (2) of FIG. 4, when the vehicle 1 is in the second state, the second region 12 maintains the first light transmittance, and the first region 11 has the second light transmittance. The second light transmittance is greater than the first light transmittance. For example, the first light transmittance may be a transmittance close to opaqueness, and the second light transmittance may be a transmittance close to transparency. The first light transmittance may also include a case where the light transmittance is reduced by diffusing transmitted light, like frosted glass.

[0025] Thereafter, as shown in FIG. 4(3), the opening operation of the door 4 in the first direction is completed.

[0026] In the above, the first state is a state in which there is no trigger to open the door 4 when the vehicle 1 is in a running state or a stopped state. The second state is a state in which there is a trigger to open the door 4 when the vehicle 1 is at least in a stopped state. An example of a trigger to open the door is when a person manually opens the door 4 when the door 4 is a manual door. An example of a trigger to open the door is when a driver performs an operation to open the door 4 when the door 4 is an automatic door, a person stands in front of the door 4, or the destination is reached by navigation or automatic driving. In addition, the second state may be a state in which the vehicle 1 is stopped, and at least one of the following may be added: the speed of the vehicle 1 is 0, the parking brake is ON, the foot brake is ON, and the door 4 is unlocked.

[0027] FIG. 5 is a diagram for explaining a second example of the relationship between the opening operation of the door 4 and the change in light transmittance of the light blocking member 5 according to the first embodiment.

[0028] As shown in FIG. 5(1), when the vehicle 1 is in a first state, the first area 11 and the second area 12 of the light blocking member 5 of the door 4 have a first light transmittance.

[0029] As shown in FIG. 5(2), when the vehicle 1 is in the second state, the second region 12 remains at the first light transmittance, and the first region 11 has the second light transmittance.

[0030] After that, as shown in FIG. 5(3), the first region 11 remains at the second light transmittance, and the second region 12 becomes the second light transmittance.

[0031] Thereafter, as shown in FIG. 5(4), the opening operation of the door 4 in the first direction is completed.

[0032] By performing the actions shown in FIG. 4 or FIG. 5, a person can see the manner in which the light-shielding member 5 of the door 4 changes sequentially from the first light transmittance to the second light transmittance in the first direction, and recognize that the door 4 is opening in the first direction.

[0033] FIG. 6 is a diagram for explaining the timing between the second state and the open state according to the first embodiment. In FIG.

[0034] As shown in FIG. 6, the first region 11 may be disposed so as to contact one end of the light blocking member 5 in the first direction, and the second region may be disposed so as to contact the other end of the light blocking member 5 in the first direction.

[0035] When the vehicle 1 is in a second state, at a first point in time, the second region 12 may remain at the first light transmittance and the first region 11 may have the second light transmittance, and then at a second point in time, the first region 11 may remain at the second light transmittance and the second region 12 may have the second light transmittance.

[0036] As a first method, the vehicle 1 may start the opening operation of the door 4 before the second time point. This allows the opening operation of the door 4 to create a light and cheerful atmosphere.

[0037] As a second method, the vehicle 1 may start the opening operation of the door 4 at the same time as the second time point. This makes the change in the light transmittance of the light blocking member 5 and the opening operation of the door 4 seamless, and the opening operation of the door 4 creates a comfortable atmosphere.

[0038] As a third method, the vehicle 1 may start the opening operation of the door 4 after the second time point. This creates a dignified and stately atmosphere during the opening operation of the door 4.

[0039] FIG. 7 is a diagram for explaining a third example of the relationship between the opening operation of door 4 and the change in light transmittance of light blocking member 5 according to the first embodiment.

[0040] 7, the light blocking member 5 includes a first region 11, a second region 12, and a third region 13. The third region 13 is adjacent to the second region 12. The first region 11, the second region 12, and the third region 13 are arranged along a first direction.

[0041] As shown in FIG. 7(1), when the vehicle 1 is in a first state, the first area 11, the second area 12, and the third area 13 of the light blocking member 5 of the door 4 have a first light transmittance.

[0042] As shown in FIG. 7(2), when the vehicle 1 is in the second state, the second region 12 and the third region 13 remain at the first light transmittance, and the first region 11 has the second light transmittance.

[0043] As shown in FIG. 7(3), thereafter, the first region 11 remains at the second light transmittance, the third region 13 remains at the first light transmittance, and the second region 12 becomes at the second light transmittance.

[0044] As shown in FIG. 7(4), thereafter, the first region 11 and the second region 12 maintain the second light transmittance, and the third region 13 changes to the second light transmittance.

[0045] As shown in FIG. 7(5), the opening operation of the door 4 in the first direction is then completed.

[0046] 7, a person can see the state in which the light blocking member 5 changes sequentially from the first light transmittance to the second light transmittance in the first direction, and recognize that the door 4 opens in the first direction.

[0047] FIG. 8 is a diagram for explaining a fourth example of the relationship between the door opening operation and the change in light transmittance of the light blocking member 5 according to the first embodiment.

[0048] In the light blocking member 5, (N-2) regions are arranged in order along the first direction between the first region and the second region, where N is an integer equal to or greater than 3, and FIG. 8 shows the case where N=4.

[0049] The first region is the first region, and the second region is the Nth region.

[0050] When the vehicle 1 is in a first state, the first region (first region) to the Nth region (Nth region) have a first light transmittance.

[0051] When the vehicle 1 is in the second state, at a first point in time, the second region (second region) to the Nth region (Nth region) maintain the first light transmittance, and the first region has the second light transmittance.

[0052] Thereafter, the second region through the (N-1)th region have the first light transmittance followed by the second light transmittance.

[0053] Then, at a second point in time, the first region through the Nth region have a second light transmittance.

[0054] Next, the opening operation of the door 4 in the first direction is completed.

[0055] Here, the first time between the first time point and the second time point corresponds to the second time between the start time point and the completion time point of the opening operation of the door 4. Note that, in Fig. 8, the start time point of the opening operation of the door 4 is the second time point, but the start time point of the opening operation of the door 4 may be earlier than the second time point or later than the second time point.

[0056] The first time corresponding to the second time may be between 60% and 140% of the second time. This allows a person to estimate the second time from the start to the completion of the opening operation of the door 4 from the first time when the light blocking member 5 changes from the first light transmittance to the second light transmittance.

[0057] FIG. 9 is a diagram showing a modified example of the method for changing the light transmittance of the light blocking member 5 according to the first embodiment.

[0058] In the present embodiment, the description that the entire area of ​​the light blocking member 5 has the first light transmittance (eg, non-transmitting) may be changed to a part having the second light transmittance (eg, transmitting) as shown in FIG. 9(1).

[0059] In addition, in this embodiment, the description that the entire area of ​​the light-shielding member 5 has the second light transmittance (e.g., transmission) may be changed to a case where only a portion of the area has the first light transmittance (e.g., non-transmission), as shown in (4) or (5) of Figure 9.

[0060] Moreover, when each region changes from the first light transmittance to the second light transmittance, the first light transmittance and the second light transmittance may be alternately repeated when focusing on smaller regions. In other words, when each region changes from the first light transmittance to the second light transmittance, the average light transmittance of each region may change from the first light transmittance to the second light transmittance. In this case, as shown in (1) to (4) of FIG. 9, the average light transmittance of each region (first region 11, second region 12, and third region 13) of the light blocking member 5 may change from the first light transmittance to the second light transmittance in sequence in the first direction, and then, as shown in (5), the door 4 may open.

[0061] FIG. 10 is a diagram showing a modified example of a portion where the light transmittance of the light blocking member 5 according to the first embodiment changes.

[0062] The portion of the light blocking member 5 where the light transmittance changes does not necessarily have to be the entire surface of the light blocking member 5, and may be, for example, a strip-like shape along the first direction as shown in Fig. 10. In this case, as shown in (1) to (4) of Fig. 10, each region (first region 11, second region 12, third region 13) of the strip-like portion of the light blocking member 5 may change from the first light transmittance to the second light transmittance in sequence in the first direction, and then, as shown in (5) of Fig. 10, the door 4 may perform an opening operation.

[0063] The portion other than the rectangular portion may have a first light transmittance (eg, non-transmitting) or a second light transmittance (eg, transparent).

[0064] FIG. 11 is a block diagram showing an example of a device provided in the vehicle 1 according to the first embodiment.

[0065] The vehicle 1 includes a door handle switch 31, a human detection sensor 32, a door control switch 33, a dimming control device 34, a door control device 35, a vehicle control device 36, a light blocking member 5, and a door 4.

[0066] The door 4 and the light blocking member 5 are as described above.

[0067] The door handle switch 31, the human detection sensor 32, the door control switch 33, the dimmer control device 34, the door control device 35, and the vehicle control device 36 can transmit and receive information to and from each other via an in-vehicle network 37. Examples of the in-vehicle network 37 include a Controller Area Network (CAN), a Local Interconnect Network (LIN), and FlexRay.

[0068] The door handle switch 31 is a switch for detecting whether or not the handle (door handle) of the door 4 is gripped. The door handle switch 31 may be turned OFF when the door handle is not gripped, and turned ON when the door handle is gripped.

[0069] The human detection sensor 32 is a sensor for detecting a person standing in front of the door 4 inside the vehicle (a person about to get off). In addition, the human detection sensor 32 may be a sensor for detecting a person standing in front of the door 4 outside the vehicle (a person about to get on). Examples of the human detection sensor include a photoelectric sensor, an infrared sensor, and a LiDAR.

[0070] The door control switch 33 is a switch that switches whether the door 4 is automatically opened or closed. For example, when the door control switch 33 is ON, the door 4 is automatically opened when a predetermined condition is satisfied. The predetermined condition is, for example, the second state described above. When the door control switch 33 is OFF, the door 4 is automatically closed.

[0071] The light control device 34 is a device that controls the light transmittance of the light blocking member 5 of the door 4. The change from the first light transmittance to the second light transmittance and the change from the second light transmittance to the first light transmittance in the first region 11, the second region 12, the third region 13, etc. of the light blocking member 5 described above may be caused by the light control device 34.

[0072] The door control device 35 is a device that uses an actuator to control the opening and closing of the door 4. The opening and closing of the door 4 described above may be performed by the door control device 35.

[0073] The vehicle control device 36 manages the running state and the stopped state of the vehicle 1. When the door handle switch 31 detects the gripping of the handle of the door 4, the vehicle control device 36 controls the light transmittance of the light blocking member 5 through the light control device 34 as described above, and controls the opening and closing of the door 4 through the door control device 35 as described above. When the human detection sensor 32 detects a human, the vehicle control device 36 controls the light transmittance of the light blocking member 5 through the light control device 34 as described above, and controls the opening and closing of the door 4 through the door control device 35 as described above. The vehicle control device 36 may be read as an Electronic Control Unit (ECU), a processor, a Central Processing Unit (CPU), a controller, or the like. The vehicle control device 36 may include a volatile storage medium and a non-volatile storage medium such as a memory and a storage. The vehicle control device 36 may realize the function according to the present embodiment by executing a predetermined computer program. Further examples of the processing performed by the vehicle control device 36 will be described later.

[0074] <Overall flow> 12 is a flowchart showing an example of a door control process according to the embodiment 1. The vehicle control device 36 may execute the following process.

[0075] The vehicle control device 36 determines whether or not the human detection sensor 32 detects a person in front of the door 4 (S101).

[0076] In step S101, when it is determined that a person is detected in front of the door 4 (S101: YES), the vehicle control device 36 executes a transmission process on the light blocking member 5 (S102). The details of this transmission process will be described later (see FIG. 13), and as a result, at least a part of the light blocking member 5 becomes the second light transmittance (for example, a transmission state) as described above. Then, the vehicle control device 36 determines whether the door control switch 33 is ON (S103).

[0077] In step S103, if the door control switch 33 is OFF (S103: NO), the vehicle control device 36 returns the process to step S101. That is, the vehicle control device 36 does not start the door opening operation. This is because when the door control switch 33 is OFF, the door 4 is in a state to be closed.

[0078] In step S103, if the door control switch 33 is ON (S103: YES), the vehicle control device 36 executes control to open the door 4 via the door control device 35 (S104). This opens the door 4. Then, the vehicle control device 36 returns the process to step S101.

[0079] In step S101, if it is determined that no person is detected in front of the door 4 (S101: NO), the vehicle control device 36 determines whether the door handle switch 31 is ON or not (i.e., whether the door handle is being gripped or not) (S110).

[0080] In step S110, if the door handle switch 31 is ON (S110: YES), the vehicle control device 36 advances the process to step S120.

[0081] In step S110, if the door handle switch 31 is OFF (S110: NO), the vehicle control device 36 determines whether the door control switch 33 is ON (S111).

[0082] In step S111, if the door control switch 33 is ON (S111: YES), the vehicle control device 36 advances the process to step S120.

[0083] In step S120, the vehicle control device 36 executes a transmission process for the light blocking member 5 (S120). Details of the transmission process will be described later (see FIG. 13). Then, the vehicle control device 36 executes control to open the door 4 through the door control device 35 (S121). This opens the door 4. However, if the door 4 is a manual door, the vehicle control device 36 may automatically unlock the door in step S121 so that the door can be opened by hand. Then, the vehicle control device 36 returns the process to step S101.

[0084] In step S11, if the door control switch 33 is OFF (S111: NO), the vehicle control device 36 executes control to close the door through the door control device 35 (S130). As a result, the door 4 closes. However, if the door 4 is a manual door, the door may be automatically locked in S130 so that it cannot be opened by hand. Then, the vehicle control device 36 executes an opacity process on the light-shielding member 5 (S131). Note that the details of the opacity process will be described later (see FIG. 14). As a result, at least a part of the light-shielding member 5 has the first light transmittance (for example, an opaque state). Then, the vehicle control device 36 returns the process to step S101.

[0085] <Transparency processing> 13 is a flowchart showing an example of the transparency process according to Embodiment 1. This process corresponds to details of the processes in steps S102 and S120 in FIG.

[0086] The vehicle control device 36 determines whether or not the entire area of ​​the light blocking member 5 already has the second light transmittance (for example, a transmissive state) (S201).

[0087] If all the regions already have the second light transmittance (S201: YES), the vehicle control device 36 completes this process and returns to the process that called it.

[0088] If at least a portion of the area does not have the second light transmittance (S201: NO), the vehicle control device 36 sets the variable i to 1 (initial value) (S202).

[0089] The vehicle control device 36 changes the light transmittance of the i-th area of ​​the light blocking member 5 from the first light transmittance to the second light transmittance through the light adjustment control device 34 (S203).

[0090] The vehicle control device 36 adds (increments) 1 to i (S204).

[0091] The vehicle control device 36 judges whether or not "i>number of regions" (S205). The number of regions is the number of regions in the light blocking member 5. For example, in the case of FIG. 4, FIG. 5 or FIG. 6, the number of regions is 2, in the case of FIG. 7, FIG. 9 or FIG. 10, the number of regions is 3, and in the case of FIG. 8, the number of regions is N.

[0092] In step S205, if it is determined that "i≦the number of regions" (S205: NO), the vehicle control device 36 returns the process to step S203.

[0093] In step S205, if it is determined that "i>the number of regions" holds (S205: YES), the vehicle control device 36 ends this process and returns the process to the caller.

[0094] Through the above process, the regions of the light blocking member 5 are sequentially changed in the first direction from the first light transmittance (eg, non-transmitting) to the second light transmittance (eg, transmitting).

[0095] <Opacity processing> 14 is a flowchart showing an example of the opacity process according to Embodiment 1. This process corresponds to details of the process of step S131 in FIG.

[0096] The vehicle control device 36 determines whether or not all the areas already have the first light transmittance (S301).

[0097] If all the areas already have the first light transmittance (S301: YES), the vehicle control device 36 completes this process and returns to the process that called it.

[0098] If at least a portion of the regions does not have the first light transmittance (S301: NO), the vehicle control device 36 sets the variable n to the number of regions (initial value) (S302).

[0099] The control device changes the light transmittance of the nth region from the second light transmittance to the first light transmittance through the dimming control device 34 (S303).

[0100] The vehicle control device 36 subtracts (decrements) 1 from n (S304).

[0101] The vehicle control device 36 determines whether or not "n≦0" (S305).

[0102] In step S305, if it is determined that "n>0" holds (S305: NO), the vehicle control device 36 returns the process to step S303.

[0103] In step S305, if it is determined that "n≦0" holds (S305: YES), the vehicle control device 36 ends this process and returns the process to the caller.

[0104] Through the above process, the regions of the light blocking member 5 are sequentially changed in the second direction from the second light transmittance (eg, transmission) to the first light transmittance (eg, non-transmission).

This allows the person A to recognize that the door 114 can be opened in the first direction in which the door becomes gradually transparent. (S35) to (S38) Person A manually opens the door 114. Note that the operations of steps S35 to S38 can be performed by Person A at any time, regardless of whether the processing of steps S32 to S34 is completed or not.
