Abstract

A vehicle operation detection device includes sensors laid out in a vehicle along an axis in an opening-closing direction of a door of the vehicle. When the user moves a part of a body toward the sensors and a motion of moving the part of the body along the axis is detected, the sensors detect an opening-closing operation for the door. The vehicle operation detection device further includes light-emitting members laid out in the vehicle along the axis in the opening-closing direction and an operation direction indicator configured to drive the light-emitting members in sequence in a first direction in a fully-closed state of the door and drives the light-emitting members in sequence in a second direction in a fully-open state of the door.

First claim

1 . A vehicle operation detection device comprising:
sensors laid out in a vehicle along an axis in an opening-closing direction of a door of the vehicle and configured to individually output a detection signal that changes when a part of a body of a user moves toward the sensors, wherein when the user moves the part of the body toward the sensors and a motion of moving the part of the body along the axis is detected, the sensors detect an opening-closing operation for the door, and the vehicle operation detection device further comprises: light-emitting members laid out in the vehicle along the axis in the opening-closing direction; and an operation direction indicator configured to drive the light-emitting members in sequence in a first direction extending along the axis and corresponding to an opening direction in a fully-closed state of the door and configured to drive the light-emitting members in sequence in a second direction extending along the axis and corresponding to a closing direction in a fully-open state of the door.

2 . The vehicle operation detection device according to claim 1 , wherein
the number of the light-emitting members is three or more, one of the light-emitting members that is located on a middle in the axis being a middle light-emitting member, and when the door is in a semi-open state, the operation direction indicator is configured to drive the light-emitting members in sequence in the first direction toward the middle light-emitting member and drive the light-emitting members in sequence in the second direction toward the middle light-emitting member.

3 . The vehicle operation detection device according to claim 1 , wherein, when ID authentication executed by a communication member that wirelessly communicates with a portable device carried by the user is established, the operation direction indicator is configured to drive the light-emitting members in correspondence with a position of one of the sensors toward which the user should initially move the part of the body.

4 . The vehicle operation detection device according to claim 1 , wherein, when the opening-closing operation for the door is detected, the operation direction indicator is configured to drive the light-emitting members such that all the light-emitting members turn on or blink, or such that all the light-emitting members turn off.

5 . The vehicle operation detection device according to claim 1 , wherein one of the sensors is any one of an electrode of a capacitance sensor, an optical sensor, an ultrasonic sensor, and a heat sensor.

6 . A vehicle operation detection device comprising:
a set of sensors laid out in a vehicle in a first direction corresponding to an opening direction of a door of the vehicle, wherein each of the sensors is configured to detect a part of a body of a user, and the vehicle operation detection device is configured to detect an opening operation for the door when the user moves the part of the body toward one of the sensors and moves the part of the body in the first direction, and detect a closing operation for the door when the user moves the part of the body toward another one of the sensors and moves the part of the body in a second direction that is opposite to the first direction; a set of light-emitting members laid out in the vehicle in the first direction; and processing circuitry configured to drive the light-emitting members in sequence in the first direction when the door is in a fully-closed state and configured to drive the light-emitting members in sequence in the second direction when the door is in a fully-open state.

7 . The vehicle operation detection device according to claim 6 , wherein
the set of light-emitting members includes a first light-emitting member, a second light-emitting member, and a third light-emitting member laid out in sequence in the first direction, and when the door is in a semi-open state, the processing circuitry is configured to drive the first light-emitting member and the second light-emitting member in sequence and configured to drive the third light-emitting member and the second light-emitting member in sequence.

8 . The vehicle operation detection device according to claim 6 , wherein
the set of light-emitting members includes a first light-emitting member and a second light-emitting member laid out in sequence in the first direction, the set of the sensors includes a first sensor and a second sensor laid out in sequence in the first direction, the first sensor and the second sensor respectively corresponding to the first light-emitting member and the second light-emitting member, when the door is in the fully-closed state, the processing circuitry is configured to drive the first light-emitting member and drive, upon detection of the part of the body by the first sensor, the second light-emitting member, and when the door is in the fully-open state, the processing circuitry is configured to drive the second light-emitting member and drive, upon detection of the part of the body by the second sensor, the first light-emitting member.

9 . The vehicle operation detection device according to claim 6 , wherein
the set of light-emitting members includes a first light-emitting member and a second light-emitting member laid out in sequence in the first direction, when the door is in the fully-closed state, the processing circuitry is configured to drive the first light-emitting member and the second light-emitting member in sequence, and when the door is in the fully-open state, the processing circuitry is configured to drive the second light-emitting member and the first light-emitting member in sequence.

10 . The vehicle operation detection device according to claim 6 , wherein, when reception of the opening operation or the closing operation for the door is completed, the processing circuitry is configured to drive the light-emitting members such that all the light-emitting members turn on, blink, or turn off.

11 . The vehicle operation detection device according to claim 6 , wherein
the door is a sliding door arranged at a side part of the vehicle and configured to move in a horizontal direction, the sliding door is configured to move in a rearward direction to change from the fully-closed state to the fully-open state and configured to move in a frontward direction to change from the fully-open state to the fully-closed state, and the first direction is the rearward direction and the second direction is the frontward direction.

12 . The vehicle operation detection device according to claim 6 , wherein
the door is a back door coupled to a rear part of the vehicle by a door hinge and configured to move in a vertical direction while pivoting around the door hinge, the back door is configured to move in an upward direction to change from the fully-closed state to the fully-open state and configured to move in a downward direction to change from the fully-open state to the fully-closed state, and the first direction is the upward direction and the second direction is the downward direction.
