It is housed in the space S1 where the In this embodiment, the first piezoelectric vibration microphone 90 attached to the back surface 50B of the outer panel 50 is arranged at a position that does not come into contact with the window 40 when the window 40 is housed inside the first door 30 .

Specifically, the curved portion 53 in the upper portion of the flat portion 52 is curved so as to gradually separate from the inner panel 55 as it goes downward from the upper end portion. For this reason, the space S1 gradually widens from the upper end toward the lower portion of the flat portion 52 side. That is, the space S1 is formed such that the portion corresponding to the flat portion 52 is wider than the portion corresponding to the upper portion (curved portion 53) of the flat portion 52. As shown in FIG.

A curved portion 53 at the lower portion of the flat portion 52 is curved so as to gradually separate from the inner panel 55 as it goes upward from the lower end portion. For this reason, the space S1 gradually widens from the lower end toward the upper portion on the flat portion 52 side. That is, the space S1 is formed such that the portion corresponding to the flat portion 52 is wider than the portion corresponding to the portion below the flat portion 52 (the curved portion 53).

For this reason, the first piezoelectric vibration microphone 90 attached to the back surface of the flat portion 52 is arranged in a relatively wide portion of the space S1. When the window 40 is housed inside the first door 30, the distance between the flat portion 52 of the outer panel 50 and the window 40 is greater than the thickness of the first piezoelectric vibration microphone 90 (dimension in the left-right direction in FIG. 3). is also longer.

The electronic control unit 85 is provided inside the front fender panel 11 of the vehicle and outside the first door 30 as described above. Therefore, the first wiring 91 is routed inside the vehicle 10 from a first end provided inside the first door 30 through the front end portion 31A of the first door 30 . An output signal output from the first piezoelectric vibration microphone 90 is input to the electronic control device 85 via the first wiring 91 .

The vehicle 10 also includes a second piezoelectric vibration microphone 95 attached to the second pillar 20 .
As shown in FIG. 6 , the second pillar 20 has a pillar outer 21 and a pillar inner 22 . The pillar outer 21 is made of, for example, a metal plate. The pillar outer 21 has a front surface 21A forming the outer surface of the vehicle 10 and a back surface 21B on the side opposite to the front surface 21A, that is, on the pillar inner 22 side. In the second pillar 20, the pillar outer 21 corresponds to the outer plate. The pillar inner 22 is made of resin, for example. The pillar inner 22 is provided on the vehicle inner side of the pillar outer 21 . The pillar inner 22 is partially joined to the pillar outer 21 .

The second piezoelectric vibration microphone 95 is attached to the back surface 21</b>B of the pillar outer 21 and accommodated in the space S<b>2 defined by the pillar outer 21 and the pillar inner 22 .

The second wiring 96 is routed inside the vehicle 10 . An output signal output from the second piezoelectric vibration microphone 95 is input to the electronic control device 85 via the second wiring 96 .

In such a vehicle 10, the user can open and close the second door 70 and the back door 75 by voice. That is, the voice uttered by the user outside the vehicle is transmitted as air vibrations and causes the outer panel 50 of the first door 30 and the pillar outer 21 of the second pillar 20 to vibrate. Thereby, the voice information of the user is acquired by at least one of the first piezoelectric vibration microphone 90 and the second piezoelectric vibration microphone 95 . The acquired voice information of the user is input to the electronic control unit 85 as an output signal. The electronic control unit 85 executes known voice recognition processing to determine whether or not the user outside the vehicle has uttered the first operation word for opening and closing the second door 70, and whether or not the back door 75 is opened and closed. It is determined whether or not the second operation word for is uttered. When the electronic control unit 85 determines that the user has uttered the first operation word, the electronic control unit 85 transmits a control signal to the first actuator 80 to cause the second door 70 to slide. When the electronic control unit 85 determines that the user has uttered the second operation word, the electronic control unit 85 transmits a control signal to the second actuator 88 to rotate the back door 75 . Note that the first operation word and the second operation word can be stored in the electronic control device 85 in advance.

Next, the operation and effects of this embodiment will be described.
(1) In the present embodiment, the first piezoelectric vibration microphone 90 is attached to the rear surface 50B of the outer panel 50, which is a metal outer panel forming the outer surface of the vehicle 10, in contact with the first door 30. Also, in the second pillar 20, the second piezoelectric vibration microphone 95 was attached to the rear surface 21B of the pillar outer 21, which is the outer plate of the second pillar 20, in contact therewith. Therefore, the first piezoelectric vibration microphone 90 and the second piezoelectric vibration microphone 95 are not exposed to the outside of the vehicle 10, and the electronic control device 85 provided inside the vehicle 10 from each of the piezoelectric vibration microphones 90 and 95 There is no need to form an opening in the outer surface of the vehicle 10 for routing wiring.

Each of the piezoelectric vibration microphones 90 and 95 acquires the voice information of the user outside the vehicle by converting the vibration of the outer plate into an electric signal. Therefore, it is not necessary to form an opening in the outer plate for transmitting air vibration to each of the piezoelectric vibration microphones 90 and 95 .

Thus, user's voice information can be input to the electronic control unit 85 from the piezoelectric vibration microphones 90 and 95 without forming an opening in the outer plate. Therefore, it is possible to realize the vehicle 10 that enables operation by voice while suppressing deterioration of the waterproofness of the outer surface.

In the present embodiment, the first piezoelectric vibration microphone 90 is attached to the rear surface 50B of the outer panel 50 of the first door 30 and housed in the space S1 defined by the outer panel 50 and the inner panel 55 . Therefore, it is possible to easily generate vibrations in the outer plate and to easily acquire the voice information of the user outside the vehicle. Therefore, it can contribute to increasing the sensitivity of the user's voice operation. Moreover, since the first piezoelectric vibration microphone 90 is accommodated inside the first door 30, water resistance of the first piezoelectric vibration microphone 90 can be ensured.

(3) The central portion of the outer panel 50 of the first door 30 that is not joined to the inner panel 55 transmits vibration more easily than the peripheral portion 51 that is joined to the inner panel 55 . In addition, in the outer panel 50, the flat portion 52 formed in a flat plate shape has lower flexural rigidity than the curved portion 53 formed in a curved plate shape, and easily transmits vibrations.

In this embodiment, since the first piezoelectric vibration microphone 90 is attached to the back surface of the flat portion 52 arranged on the center side of the outer panel 50 of the first door 30, the user's voice information is transmitted through the outer panel 50. can be suitably obtained. In this embodiment, the first piezoelectric vibration microphone 90 is attached not to the second door 70 that slides, but to the first door 30 that rotates. Therefore, it is not necessary to route the first wiring 91 connected to the first piezoelectric vibration microphone 90 long in consideration of the sliding movement of the door. Further, in the present embodiment, the electronic control unit 85 controls the driving of the first actuator 80 so that the second door 70, which is the left rear seat door, can be opened and closed by voice operation. Therefore, when the vehicle 10 is stopped, it is possible to encourage passengers to get on and off from the second door 70, which is likely to be arranged on the sidewalk side instead of the roadway side.

As described above, according to the present embodiment, it is possible to further facilitate the acquisition of voice information, facilitate the handling of the first wiring 91 connected to the first piezoelectric vibration microphone 90, and further improve the safety of passengers. can also contribute.

(4) In the present embodiment, the first piezoelectric vibration microphone 90 is arranged near the service hall 57 by arranging it on the front side of the vehicle at the first door 30 in the same manner as the service hall 57 . With such a configuration, even when the first door 30 is assembled by joining the outer panel 50 and the inner panel 55, the space S1 defined by the outer panel 50 and the inner panel 55 can be accessed through the service hole 57. It can be realized by attaching the first piezoelectric vibration microphone 90 to the back surface 50B of the outer panel 50 . Therefore, the work for attaching the first piezoelectric vibration microphone 90 to the outer panel 50 can be facilitated.

Also, the first piezoelectric vibration microphone 90 is arranged at a position that does not come into contact with the window 40 . Therefore, the first piezoelectric vibration microphone 90 does not interfere with the window 40 when the window 40 is opened or closed. As a result, it is also possible to secure the durability of the first piezoelectric vibration microphone 90 .

Therefore, it is possible to further improve the durability while improving the mounting workability of the first piezoelectric vibration microphone 90 .
(5) In the present embodiment, the second piezoelectric vibration microphone 95 is attached to the rear surface 21B of the pillar outer 21 in the second pillar 20 forming the opening 10A that the back door 75 opens and closes. Therefore, compared to the case where the second piezoelectric vibration microphone 95 is attached to the back door 75 , the shock when opening and closing the back door 75 is less likely to act on the second piezoelectric vibration microphone 95 . Therefore, the durability of the second piezoelectric vibration microphone 95 can be improved.

(6) In this embodiment, the first piezoelectric vibration microphone 90 arranged on the front side of the vehicle and the second piezoelectric vibration microphone 95 arranged on the rear side of the vehicle serve as piezoelectric vibration microphones for converting the vibration of the outer plate into an electric signal. and Therefore, it is possible to prevent the distance from the piezoelectric vibration microphones 90 and 95 to the user from becoming excessively long, thereby increasing the sensitivity of the user's voice operation.

(7) In the first door 30 , the sound absorbing material 65 is arranged on the inside of the vehicle with respect to the first piezoelectric vibration microphone 90 . Therefore, it is possible to make it difficult for the first piezoelectric vibration microphone 90 to detect the voice in the vehicle compartment.
