Abstract

A vehicle control device includes image capturing units, control equipment that extracts at least one living body from image information captured by the image capturing units and performs processing, and a door operating system capable of unlocking the doors of a vehicle and executing an opening operation for the doors. When a user of the vehicle is included among a plurality of the extracted living bodies and it is estimated that a predetermined type of living body is in contact with the user, the control equipment causes the doors to be operated in a first mode. When the user is included among the plurality of the extracted living bodies and it is estimated that the predetermined type of living body is not in contact with the user, the control equipment causes the doors to be operated in a second mode that differs from the first mode.

First claim

What is claimed is:

1. A vehicle control device, comprising:
an image capturing unit provided in a vehicle and configured to capture an image of an external environment of the vehicle;
a control unit including at least one processor configured to extract at least one living body from image information captured by the image capturing unit and perform processing; and
an opening and closing body operating unit configured to, under control of the at least one processor, switch an opening and closing body of the vehicle from a locked state to an unlocked state and execute an opening operation of the opening and closing body;
wherein the at least one processor identifies a type of the living body that was extracted; and
in a first mode a user of the vehicle is included among a plurality of the living bodies that were extracted and the at least one processor estimates that a predetermined type of living body that was identified is in contact with the user, the at least one processor causes the opening and closing body to be operated in the first mode; and
in a second mode the user is included among the plurality of living bodies that were extracted and the at least one processor estimates that the predetermined type of living body that was identified is not in contact with the user, the at least one processor causes the opening and closing body to be operated in the second mode that differs from the first mode.

2. The vehicle control device according to claim 1 , wherein:
in the first mode, the opening and closing body is unlocked, and further, the opening and closing body is made to perform the opening operation; and
in the second mode, the opening and closing body is unlocked, and the opening and closing body remains closed while being openable.

3. The vehicle control device according to claim 2 , wherein, from among a plurality of the opening and closing bodies provided on the vehicle, the opening and closing body that is operated in the first mode or the second mode is a seat adjacent to a rear seat of the vehicle.

4. The vehicle control device according to claim 2 , wherein, after the opening and closing body has been set in the second mode, the at least one processor changes the opening and closing body to the first mode, in a case it is recognized that the user and the predetermined type of living body have come into contact with each other.

5. The vehicle control device according to claim 1 , wherein:
the image capturing unit includes external environment sensors installed respectively on both sides in a lateral direction of the vehicle; and
the at least one processor causes the opening and closing body that is on a same side as one of the external environment sensors that has captured an image of the user, to be operated in the first mode or the second mode.

6. The vehicle control device according to claim 1 , wherein, when the user is recognized, the at least one processor switches, from among a plurality of the opening and closing bodies provided on the vehicle, a door adjacent to a driver's seat from a locked state into an unlocked state, and further causes the door to perform the opening operation.

7. The vehicle control device according to claim 1 , wherein the at least one processor generates a schematic skeleton figure of the living body that was extracted from the captured image information, and estimates whether or not the user and the predetermined living body are in contact with each other, based on a generated schematic skeleton figure of the user, and a generated schematic skeleton figure of the predetermined type of living body.

8. The vehicle control device according to claim 7 , wherein the at least one processor estimates that the user and the predetermined type of living body are in contact with each other, based on a skeleton figure of an arm of either one of the schematic skeleton figure of the user and the schematic skeleton figure of the predetermined type of living body being in contact with another skeleton figure.

9. The vehicle control device according to claim 1 , wherein, from among a plurality of the opening and closing bodies provided on the vehicle, the at least one processor causes the opening and closing body that is operated in the first mode or the second mode, to be settable by the user.

10. A method of operating an opening and closing body by a vehicle control device, wherein the vehicle control device includes:
an image capturing unit provided in a vehicle and configured to capture an image of an external environment of the vehicle;
a control unit including at least one processor configured to extract at least one living body from image information captured by the image capturing unit and perform processing; and
an opening and closing body operating unit configured to, under control of the at least one processor, switch an opening and closing body of the vehicle from a locked state to an unlocked state and execute an opening operation of the opening and closing body;
the method comprising: with the at least one processor,
unlocking the opening and closing body by the opening and closing body operating unit in a case that a user of the vehicle is authenticated;
estimating contact between the user and a predetermined type of living body, based on image information captured by the image capturing unit; and
causing the opening and closing body operating unit to open the unlocked opening and closing body, in a case that the at least one processor estimates that the user and the predetermined type of living body are in contact with each other.
