<Embodiment>
Hereinafter, embodiments of the present invention will be described with reference to FIGS.

<Configuration of vehicle opening / closing body control device>
The configuration of the vehicle opening / closing body control apparatus according to this embodiment will be described with reference to FIG.

  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, and a direction. The change drive unit 600, the drive control unit 700, the monitor 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 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. 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. Detect intention. Detailed configurations of the light irradiation unit 300, the operation intention detection unit 400, and the like will be described later.

  When the light irradiation unit 300 and the operation intention detection unit 400 are provided at a plurality of locations, the output control unit 500 detects the irradiation of the light irradiation unit 300 and the operation intention detection provided at the plurality of locations. The output signal with the part 400 is controlled. For example, as a control method, control is performed such that the light irradiation unit 300 and the operation intention detection unit 400 corresponding to the current position of the user detected by the current position detection unit 200 are operated. Further, when the current position detection unit 200 cannot detect the operation intention by the operation intention detection unit 400 even after a predetermined time has elapsed, the output control unit 500 detects the operation intention at another location in the detection area. The irradiation of the light irradiation unit 300 provided at a plurality of locations and the output signal of the operation intention detection unit 400 are controlled so as to form a display.

  The direction change drive unit 600 drives the motor, for example, to change the direction of the light source of the light irradiation unit 300 according to the current position where the user detected by the current position detection unit 200 exists, for example, the light irradiation unit 300. Change the irradiation direction. In this case, the output direction of the operation intention detection unit 400 is also changed in accordance with the output direction of the light irradiation unit 300.

  The drive control unit 700 controls the direction change drive unit 600. For example, the drive control unit 700 operates the direction change driving unit 600 and corresponds to the light source direction of the light irradiation unit 300 and the operation intention detection unit 400 corresponding to the current position of the user detected by the current position detection unit 200. Change the output direction of the output signal. Further, when the current position detection unit 200 cannot detect the operation intention by the operation intention detection unit 400 even after a predetermined time has elapsed, the current position detection unit 200 confirms the position of the user again, and the user exists. Depending on the position, the drive control unit 700 controls the direction change drive unit 600 so as to form a display for detecting the intention of operation at another location in the detection area.

  When the current position detection unit 200 is provided at a plurality of locations, the monitor unit 800 monitors the detection status of the current position detection unit 200 provided at the plurality of locations. When the monitor unit 800 monitors the current position detection unit 200 that detects the presence of the user, the output control unit 500 corresponds to the direction of the current position detection unit 200 that detects the presence of the user. The light irradiation unit 300 and the operation intention detection unit 400 are operated to form a display for detecting the operation intention. Further, when the current position detection unit 200 that detects the presence of the user is monitored, the drive control unit 700 corresponds to the direction of the current position detection unit 200 that detects the presence of the user. The direction of the light source 300 is changed to form a display for detecting an operation intention. In this case, the output direction of the operation intention detection unit 400 is also changed in accordance with the output direction of the light irradiation unit 300.

  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 driving unit 910 drives the vehicle opening / closing body based on a control signal from the vehicle opening / closing body control unit 900. The vehicle opening / closing body includes at least a back door and a side door (rear door).

  The device control unit 1000 receives signals from each unit, and controls the operation of the entire vehicle opening / closing body control device according to a control program stored in a ROM (Read Only Memory). For example, when a person approaches the vehicle within a predetermined distance, the light irradiation unit 300 controls to form a display for detecting the intention of operation at a predetermined location outside the vehicle.

<Configuration of authentication unit>

  Transponder 150 is built in portable device 140 that is given in advance to one vehicle. That is, when the user who owns the portable device 140 approaches a predetermined distance, the portable device 140 receives the activation signal (low frequency) output from the antenna coil 122 of the transceiver 120 by the electronic control device 110 by the transponder 150. The activation signal is an oscillation signal having a predetermined frequency output from the electronic control device 110 via the antenna coil 122. The portable device 140 is activated when the transponder 150 receives the emitted activation signal, The transponder 150 transmits the encrypted portable device side identification code IDa.

  The antenna coil 122 is activated by the electronic control unit 110 intermittently at predetermined time intervals. Then, an activation signal having a predetermined frequency is transmitted. When the transmitter / receiver 120 receives a response signal from the portable device 140, the current position detection unit 200 thereafter grasps the position of the portable device 140.

  Note that the portable device side identification code IDa of the portable device 140 is registered in advance as the vehicle-mounted side identification code IDb in the electronic control device 110, and the electronic control device 110 receives the portable device side identification code input via the transceiver 120. The code IDa is checked against the registered vehicle-side identification code IDb.

  As shown in FIG. 2, the electronic control unit 110 includes a central processing unit (hereinafter referred to as CPU) 111, a read only memory (hereinafter referred to as ROM) 112, a nonvolatile memory (hereinafter referred to as EEPROM) 113, and a readable and writable memory.

  The EEPROM 113 constitutes storage means. The RAM 114 temporarily stores the calculation processing result of the CPU 111.

  The CPU 111 intermittently transmits an oscillation signal having a predetermined frequency from the antenna coil 122 activated by the electronic control device 110 at predetermined time intervals. In response to the oscillation signal, the transmitter / receiver 120 receives the portable device side identification code IDa stored in the transponder of the portable device 140 transmitted from the portable device 140 to the transmitter / receiver 120, and inputs it to the CPU 111.

  The CPU 111 collates the input portable device side identification code IDa with the in-vehicle side identification code IDb stored in the EEPROM 113.

<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.

  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 first light field 30 is irradiated on the surface of the roadway in the direction in which the opening end opened on one side is away from the vehicle 1. In the embodiment shown, the light fields 20 and 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). . Further, in an embodiment (not shown) of the present invention, in order to trigger the automatic opening process of the corresponding opening / closing part 2 (start or release), both the light fields 20 and 30 are connected to the passenger door and / or the trunk lid. It can also be generated on the road surface in the region.

  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 changes the reflection state of both the light fields 20 and 30 as, for example, a photodiode 415 arranged in the light irradiation unit 300 and the operation intention detection unit 400 or 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.

  The light emitting diode 430 of the first optical transmitter 11 generates the first transmission light beam 5.1 in the first frequency region, for example, the infrared frequency region including the frequency of the invisible light spectrum.

In order to project a point (circle) with a predetermined diameter, an infrared diode (operation intention detection unit) 420 having a predetermined radiation angle is provided.

  In the illustrated embodiment, this projection is performed in the infrared frequency region, i.e., the region invisible to the human eye. 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. In order to make it visible, a laser diode 320 having a predetermined emission angle is provided. 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.

After confirming, the light irradiation unit 300 may form a display for detecting the intention of operation at another location in the detection area.

  Further, as shown in FIG. 11, 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 300a to 300c are provided corresponding to one current position detection unit 200, and it is determined that the current position detection unit 200 is closest to the area where U of the user is detected. You may make it form the display which detects an operation intention in another location in the detection area by either of the light irradiation parts 300a-c. 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, as shown in FIG. 10, a plurality of current position detection units 200 may be provided for each area, or the light irradiation unit 300 may be rotated to change the display position of the operation spot X.
