<Configuration of light irradiation unit, operation intention detection unit, etc.>
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.

  The light irradiation unit 500, the operation intention detection unit 600, 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 region of the vehicle 1 in order to automatically open the automatic opening / 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 500 and the operation intention detection unit 600. 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 '. The optical measuring device 10 comprises a first light transmitter 11, which has a desired shape of the first light irradiation field 30 on the road surface of the monitoring area 3, for example a U shape or a horseshoe shape. The light emitting diodes 430 are arranged at specific angles with respect to each other and each have a predetermined radiation angle. In an alternative embodiment not shown, the at least one first optical transmitter 11 has only one transmission diode to generate the individual light point portions 32 and the individual light points of the first light field 30. In order to project the portion 32 on the road surface in a desired shape, an optical system that disperses the light of the transmission diode at various predetermined radiation angles is provided.

In order to distinguish the resulting received light rays 7.1, 7.2, the first transmitted light beam 5.1 and the second transmitted light beam 5.2 are emitted in a time-shifted manner in a time multiplexed manner. This time multiplexing scheme makes it possible to better allocate the reflected received light rays 7.1, 7.2 to the first or second illumination field 30,20. In order to make the second light irradiation field 20 visible, the optical measuring device 10 has a third optical transmitter 13. The third optical transmitter is used for marking a second light irradiation field 20 having a desired shape on the road surface around the first light irradiation field 30, for example, a point (circle) having a predetermined diameter, and a user.

Therefore, the laser diode 320 of the third optical transmitter 13 generates radiated light in the frequency region of the visible light spectrum.

  In the present embodiment, at least one first optical transmitter 11 generates a first transmission beam 5.1 in the first frequency domain, and at least one second optical transmitter 12 is different from the first frequency domain. 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.

  As shown in FIG. 5, the evaluation and control unit 19 connects at least one first optical transmitter 11 and at least one second optical transmitter 12 to a Halios (registered trademark): High Ambient Light Independent Optical System. ) Based on the measurement principle, the received rays 7.1, 7.2 received by the at least one optical receiver 15 for evaluating the object are evaluated according to this Harris measurement principle.

  For this purpose, the optical measuring device 10 comprises a fourth optical transmitter 14, which comprises at least one compensating light emitting diode, the first optical transmitter 11 and the second optical transmitter 12. A first modulator 16 for modulating, a second modulator 17 for modulating the fourth optical transmitter 14, and a synchronous demodulator 18 are included. In order to apply the Harios measurement principle, the fourth optical transmitter 14 has compensation light-emitting diodes (not shown) for the first optical transmitter 11 and the second optical transmitter 12, and this compensation light-emitting diode is also a first light-emitting diode. Similar to the first optical transmitter 11 and the second optical transmitter 12, it operates in a time multiplexing manner.

If the optical receiver according to FIG. 6 consists of at least one camera 15 ′, the image acquired by this camera is transmitted to the evaluation and control unit 19 for evaluation in order to generate an output signal _SAus . This evaluation can be performed, for example, by pixel evaluation of image pixels.
