[0011] In addition, since the placement regions of both electrodes are completely separated, the size of the sensor requires an area equal to or greater than the sum of the areas of both sensors, and there is also a limit to the miniaturization of the sensor.

[0071] (overall overview)

[0072] figure 1 The structure of the vehicle door control device U (hereinafter, abbreviated as "control device U") according to the first embodiment of the present invention is shown. figure 2 The detection mode of the control device U is schematically shown. This control device U is provided, for example, in a door handle H of a vehicle, inside parts around a door, inside appearance parts of an exterior, or the like. According to this control device U, it is possible to detect the opening and closing operation of the direct contact sensor S as the opening and closing operation of the vehicle door D by the user of the vehicle, the opening and closing operation of waving the hand away from the sensor S, and the like. Also, the installation area of ​​the sensor S can be reduced. Hereinafter, this control apparatus U is demonstrated based on each figure.

[0119] Such as Figure 6 As shown, the outer shapes of the first electrode 1 and the second electrode 2 only need to be such that the second electrode 2 protrudes to one side of the first electrode 1 . For example, when the door handle H is positioned above the sliding door D1, and the door handle H is provided on a horizontally extending protrusion formed on the surface of the sliding door D1, the user's hand, body, and sliding A case where the position where the door D1 contacts is limited to the area below the door handle H. As shown in FIG. In this case, when a finger or the like is brought close to the door handle H to instruct opening and closing of the door, the operation may be performed by putting the finger on the door handle H from slightly above the door handle H.

[0120] In such a case, the first electrode 1 can be shifted upward so that the second electrode 2 protrudes only downward relative to the first electrode 1 .

[0121] According to this configuration, ...

Abstract

Provided is a small vehicle door control device capable of accurately discriminating the presence of a detection object. A vehicle door control device (U) is provided with: a first electrode (1) thatis an electrostatic sensor electrode provided with a first detection surface (1F) facing the outside of a vehicle door (D); a second electrode (2), which is an electrostatic sensor electrode that faces the first electrode, is positioned on the outside of the vehicle door with respect to the first detection surface, and faces the outside of the vehicle door; the second electrode is provided with asecond detection surface (2F) having an overlapping region and a non-overlapping region in the plane direction of each other with respect to the first detection surface; and a control part (3) that controls the first electrode and the second electrode and switches between a first detection state in which the first electrode is driven and the potential of the second electrode is set to a floating state and a second detection state in which the second electrode is driven and the potential of the first electrode is set to a ground state. An operation instruction to the vehicle door is determinedon the basis of the capacitance values measured by the first electrode and the second electrode.

Description

technical field [0001] The present invention relates to a vehicle door control device that detects a user's door opening and closing instruction, the vehicle door control device having two electrostatic sensor electrodes provided toward the outside of the vehicle door and a control unit that controls them . Background technique [0002] Conventionally, as such a door control device for a vehicle, there are devices described in the following Patent Document 1 (see paragraphs [0038] to [0041] and paragraphs [0057] to [0059], etc.), for example. [0003] In this vehicle door control device, for example, there are a sensor electrode on the center side of a rectangle and auxiliary electrodes arranged around it. The sensor electrodes detect a detection target such as a person positioned on the detection surface side. The auxiliary electrode changes the isocapacitance line on the detection surface side of the sensor electrode, and provides directivity to both electrodes. [0004...
