<Configuration of vehicle opening / closing body control device>
As shown in FIG. 1, the vehicle opening / closing body control apparatus according to the present invention includes an authentication unit 100, a current position detection unit 200, a light irradiation unit 300, an operation intention detection unit 400, an output control unit 500, a fault The object detection unit 600, the direction change drive unit 700, the drive control unit 800, the vehicle opening / closing body control unit 900, the vehicle opening / closing body drive unit 910, and the device control unit 1000 are configured.

  The authentication unit 100 performs a mutual authentication process between a transceiver mounted on the vehicle and a portable device owned by the user. The detailed configuration of the authentication unit 100 will be described later. Further, the mutual authentication processing described here is merely an example, and other processing methods may be used as long as the mutual authentication processing can be executed.

  The current position detection unit 200 detects a current position where the user exists. Specifically, the current position detection unit 200 emits infrared rays, millimeter wave radars, ultrasonic waves, and the like, and measures the distance from the human body and the object by the reflected light to detect the proximity state. is there. For example, a millimeter wave radar detects the current position of a user in a predetermined range using millimeter wave radio waves. Since this method uses radio waves, it can also be used in fog or during rain / snow. Currently, the available frequency bands are the 60 GHz band and the 76 GHz band, and technical conditions are defined as a low-power millimeter-wave radar. In addition to the millimeter wave radar or the like, the current position detection unit 200 may be configured to analyze an image using a camera, for example. The current position detection unit 200 preferably functions to detect an obstacle on the road while the vehicle is traveling.

  The light irradiation unit 300 forms a display for detecting the intention of operation on the road surface by irradiation with visible light. The operation intention detection unit 400 irradiates, for example, invisible light to an area including a display area for detecting an operation intention, and performs a user operation based on a change in the amount of light between the irradiation light and the reflected light.

Further, the light irradiation unit 300 and the operation intention detection unit 400 corresponding to the current position direction of the user detected by the current position detection unit 200 and the detection result of the obstacle by the obstacle detection unit 600 are operated.

  The obstacle detection unit 600 detects the presence or absence of an obstacle at a position where a display is scheduled to be detected to detect the user's intention to operate. Specifically, using conventional technology that detects reflected waves such as millimeter wave radar, ultrasonic waves, infrared rays, etc., the presence or absence of an obstacle is determined by evaluating and calculating the light reflected by the millimeter wave radar etc. on the obstacle.

  It is desirable to provide a plurality of obstacle detection units 600 according to the direction in which the light irradiation unit 300 forms a display on the road surface to detect the user's operation intention.

  The direction change driving unit 700 changes the direction of the light source of the light irradiation unit 300 and the output direction of the output signal from the operation intention detection unit 400, for example, by driving a motor in accordance with a control signal from the drive control unit 800. . Specifically, the direction change drive unit 700 changes the direction of the light source of the light irradiation unit in response to the obstacle detection unit 600 detecting an obstacle at a display formation planned position where the user senses the operation intention. For example, the motor is driven to change the direction of the light irradiation unit 300 and the output direction of the output signal from the operation intention detection unit 400 so as to be changed.

  The drive control unit 800 controls the direction change drive unit 700. For example, the drive control unit 800 operates the direction change driving unit 700 to change the direction of the light source of the light irradiation unit 300 and the output direction of the output signal from the operation intention detection unit 400.

  The vehicle opening / closing body control unit 900 controls the opening / closing operation of the vehicle opening / closing body when the operation intention detection unit 400 detects the user's operation intention. The vehicle opening / closing body includes at least a back door and a side door (rear door).

  The vehicle opening / closing body drive unit 910 drives the vehicle opening / closing body when there is an operation that blocks the display for detecting the formed operation intention.

  The device control unit 1000 receives signals from each unit and controls the operation of the entire vehicle opening / closing body control device in accordance with a control program stored in a ROM (Read Only Memory). For example, when a person approaches the vehicle within a predetermined distance, the operation intention detection unit 400 controls to display a display for detecting the operation intention at a predetermined location outside the vehicle. Further, in accordance with the obstacle detection result of the obstacle detection unit 600, control for selecting the light irradiation unit 300 and the operation intention detection unit 400 and control for driving the direction change drive unit 700 are performed, so that the obstacle is not in a position. The display formation position for detecting the user's operation intention is changed or determined. Furthermore, the current position detection unit 200 performs control for selecting the light irradiation unit 300 and the operation intention detection unit 400 and control for driving the direction change drive unit 700 according to the direction in which the presence of the user is detected. The position where the display for detecting the operation intention is changed or changed.

Configurations of the light irradiation unit, the operation intention detection unit, and the like according to the present embodiment will be described with reference to FIGS. 3 to 6.

  As a result, the light irradiation unit 300, the operation intention detection unit 400, and the like generate at least one optical transmitter 11, 12, 13, 14 that generates the transmission light rays 5.1, 5.2 and emits them to the monitoring region 3. And at least one optical receiver 15 for receiving the resulting received radiation 7.1, 7.2 from the monitoring area. The evaluation and control unit 19 evaluates the received rays 7.1, 7.2 in order to recognize the object.

At least one first optical transmitter 11 generates a first light irradiation field 30 having a predetermined shape on the surface of the monitoring region 3 by transmitting the first transmission light 5.1 whose direction is adjusted, The at least one second optical transmitter 12, 13 transmits the second transmitted light beam 5.2 having the direction adjusted to change the second light irradiation field 20 having a predetermined shape into the first light irradiation field 30. Generated in the adjacent peripheral part. The evaluation and control unit 19 produces a first received light beam 7.1 reflected by the surface of the first light irradiation field 30 and a second received light beam 7.2 reflected by the surface of the second light irradiation field 20. Receive via at least one optical receiver 15. The evaluation and control unit 19 recognizes during the evaluation that there has been a change in the second received light beam 7.2 reflected by the trigger object (eg the user's foot) 9 recognized in the monitoring area 3. An output signal (S _Aus ) is generated when it is recognized that the first received ray 7.1 has not been changed by the trigger object 9.

  As shown in FIG. 3, the invisible first light irradiation field 30 forms a first detection field, and in the illustrated embodiment, a shape in which one side composed of a plurality of invisible light point portions 32 is opened, Preferably it has a U shape and / or a horseshoe shape. The visible second light field 20 forms a second detection field, is located at the open end of the first light field 30 and is partially surrounded by the first light field 30. Is a single visible light point portion. The light point portions of the second light irradiation field 20 have a predetermined distance with respect to the individual light point portions 32 of the first light irradiation field 30.

  As shown in FIG. 3, the light irradiation field 30 is irradiated on the surface of the roadway in a direction in which the opening end opened on one side is away from the vehicle 1. In the embodiment shown, the light irradiation fields 20, 30 are generated on the road surface in the rear area of the vehicle 1 in order to automatically open the automatic opening and closing part 2 configured as a rear hatch (tailgate). The Further, in the embodiment (not shown) of the present invention, in order to trigger the automatic opening process of the corresponding opening / closing section 2 as a trigger (activation or release), both the light irradiation fields 20 and 30 are used as a passenger door and / or a trunk lid. It can also be generated on the road surface in the region of

  A trigger object 9 entering one of the two illumination fields 20, 30 changes the reflection of the corresponding illumination field 20, 30 and can therefore be detected. The two light fields 20, 30 are directed in one direction, and the user can, for example, place a foot 9 with a shoe on the second light field 20, which is formed as a light point part. The trigger object 9 or the foot is prevented from affecting the second light irradiation field 20. For example, when an object such as an animal or a ball crosses the monitoring area 3, both light irradiation fields 20, 30, that is, the area of the U-shaped first light irradiation field 30 and the light point portion are formed. A change of reflection is brought about in the region of the second light field 20. However, when the trigger object 9, here the foot, is placed in the opening area of the U-shaped first light irradiation field 30, only the second light irradiation field 20 formed as a light point portion can be distinguished. Is done.

  As shown in FIG. 4, the optical measurement device 10 of the vehicle 1 sets the reflection state of both the light irradiation fields 20 and 30 as, for example, a photodiode 415 arranged in the light irradiation unit 300 and the operation intention detection unit 400. Alternatively, the reflection of the two illumination fields 20, 30 is measured using correspondingly connected LEDs or an optical receiver 15 formed as a camera 15 '.

A second transmission ray 5.2 in the second frequency domain is generated. This likewise advantageously makes it possible to easily assign the reflected first or second received beam 7.1, 7.2 to the first or second illumination field 30,20. . Accordingly, the at least one first optical transmitter 11 may have a first frequency region including a frequency of an invisible optical spectrum. The second optical transmitter 12 may have a second frequency region that includes frequencies of the invisible or visible light spectrum. This means that the second optical transmitter 12 can generate an invisible second light irradiation field 20 or a visible second light irradiation field 20 on the surface of the monitoring region 3. Again, if the second optical transmitter 12 emits a second transmitted light beam 5.2 with an invisible light spectrum, the third optical transmitter 13 is used for marking or visualization of the second light irradiation field 20. can do.

The relationship between an obstacle and / or a user's current position, the light irradiation part 300, and the operation intention detection part 400 is demonstrated using FIG. 7 and FIG. 7 and 8 are views of the vehicle as viewed from above. The fan-shaped portion indicates the detection area of the obstacle detection unit 600, the black triangle indicates the obstacle S, the black circle indicates the current position of the user U, A hollow circle (solid line, alternate long and short dash line) indicates an operation spot X.

  In this description, the current position detection unit 200 has the same detection area as that of the obstacle detection unit 600, but the detection area of the current position detection unit 200 is preferably larger than the detection area of the obstacle detection unit 600. This is because the detection area of the obstacle detection unit 600 only needs to include the operation spot X for detecting the user's intention to operate.

  FIG. 7 illustrates a state in which the obstacle detection unit 600, the light irradiation unit 300, and the operation intention detection unit 400 are arranged at a plurality of locations in the vehicle. The obstacle detection unit 600, the light irradiation unit 300, and the operation intention detection unit 400 may not be arranged on the same vertical axis.

  The obstacle detection unit 600 arranged corresponding to the light irradiation unit 300 and the operation intention detection unit 400 that irradiates a preset operation spot X (X1 in this figure) is activated, and the obstacle of the operation spot X1 The presence or absence of is detected. As shown in the figure, when there is an obstacle S in the operation spot X1, the obstacle detection unit 600 detects the obstacle S, and in response to this, the apparatus control unit 1000 changes the operation spot X1 to the operation spot X2. To do. Priorities are set in advance for the operation spots X, and the apparatus control unit 1000 changes the operation spots X accordingly. In this way, the operation spot X where the obstacle S is not detected is specified, and the light irradiation unit irradiates the specified operation spot.

  When the current position detection unit 200 is provided, the obstacle detection unit 600 corresponding to the current position detection unit 200 that detects the user U is activated to detect the presence or absence of an obstacle at the operation spot X (X3 in the figure). To do. The obstacle detection unit 600 is activated at the same time, and from the operation spots X where the obstacle S is not detected, the device control unit 1000 determines the operation spot that the light irradiation unit 300 irradiates according to the priority order. Also good.

  Further, as shown in FIG. 8, when the obstacle S is detected at a preset operation spot X (X10 in this figure), the direction change driving unit 700 detects the light irradiation unit 300 and the operation intention detection. The direction of the part 400 may be changed to form the operation spot X (X11 in this figure) at another position where no obstacle is detected.

  Furthermore, as shown in FIG. 9, in a predetermined door, for example, a back door, the direction approaching the door may approach from the side door side as in the problem in the prior art. In that case, a plurality of light irradiation units 300 a to 300 c may be provided corresponding to one current position detection unit 200. An obstacle detection unit 600 arranged corresponding to the light irradiation unit 300a that irradiates a preset operation spot X (X1 in the figure) and the operation intention detection unit 400a is activated, and an obstacle of the operation spot X1 The presence or absence of is detected. As shown in the figure, when there is an obstacle S in the operation spot X1, the obstacle detection unit 600 detects the obstacle S. At the same time, the current position detection unit 200 is activated, and the operation spot where the obstacle S is not detected by any of the light irradiation units 300a to 300c determined to be closest to the area where the user's U is detected. You may make it form the display which detects an operation intention in another location in the detection area determined to be nearest to the user U among X. This configuration is effective particularly for the back door because a plurality of directions in which the user approaches can be considered from the parking situation. In this case, a plurality of current position detection units 200 may be provided for each area as shown in FIG. 7, and the display position of the operation spot X is changed by rotating the light irradiation unit 300 as shown in FIG. It may be configured.
