Door opening and closing device
First Claim
1. A door opening and closing device comprising:
- a door opening and closing drive unit capable of opening and closing a door with respect to a vehicle body;
a first detection unit and a second detection unit configured to detect a detection object around the door; and
a control unit configured to perform an opening and closing control of the door by way of the door opening and closing drive unit based on a detection result of the first detection unit and a detection result of the second detection unit, whereinthe first detection unit has a first detection range where the detection object is detectable, the second detection unit has a second detection range where the detection object is detectable, and one operation zone is set by making a portion of the first detection range and a portion of the second detection range overlap with each other,the control unit is configured to perform the opening and closing control of the door only when set movement of the detection object is detected within the operation zone based on at least one of the detection result of the first detection unit and the detection result of the second detection unit,wherein each of the first detection unit and the second detection unit has a transmission part configured to transmit a radio signal and a reception part configured to receive a reflection signal formed by the reflection of the radio signal on the detection object,the operation zone has two or more operation detection sub zones, andthe control unit includes a determination part configured to determine the operation detection sub zone in which the detection object is present among the two or more operation detection sub zones, based on the reflection signal which the reception part receives.

Abstract
A door opening and closing device includes: a door opening and closing drive unit capable of opening and closing a door with respect to a vehicle body; detection units configured to detect a detection object; and a control unit configured to perform an opening and closing control of the door based on detection results of the detection units. One operation zone is set by making a portion of a first detection range of the first detection unit and a portion of a second detection range of the second detection unit overlap with each other. The control unit is configured to perform the opening and closing control of the door only when set movement of the detection object is detected within the operation zone, based on at least one of the detection result of the first detection unit and the detection result of the second detection unit.

13. A door opening and closing device comprising:
-
a door opening and closing drive unit capable of opening and closing a door with respect to a vehicle body; a detection part disposed on the vehicle body and configured to detect a detection object around the door; an optical display unit configured to perform an optical display so as to guide a user to a set position, and a control unit configured to control the optical display unit and to perform an open/close control of the door by way of the door opening and closing drive unit, based on a detection result of the detection part, wherein the detection part includes a transmission part configured to transmit a radio signal such that the radio signal expands radially, and a reception part configured to receive a reflection signal formed by the reflection of the radio signal on the detection object, wherein the transmission part is disposed such that an output center of the radio signal is outputted in a horizontal direction from the vehicle body, the detection part includes at least a first detection unit and the second detection unit, the first detection unit has a first detection range formed by the radio signal, the second detection unit has a second detection range formed by the radio signal, and one operation zone is set by making a portion of the first detection range and a portion of the second detection range overlap with each other, the control unit is configured to perform an open/close control of the door only when set movement of the detection object is detected within the operation zone, based on at least one of a detection result of the first detection unit and a detection result of the second detection unit, and the operation zone has two or more operation detection sub zones depending on a distance from the detection part, and the optical display unit is configured to perform an optical display on a vehicle body side with respect to the first operation detection zone so as to guide a user to the first operation detection sub zone closest to the vehicle body.
