First Embodiment
1 to 4 show a vehicle door control device 10 mounted on a vehicle 1 according to a first embodiment of the present invention. As shown in FIG. 1 to FIG. 3, the door control device 10 detects the movement determined by the user outside the side door (hereinafter simply referred to as a door) 5 of the vehicle 1 to detect the door. It controls the door drive unit 21 which is an electric device of No. 5. In the following description, the vehicle length direction of the vehicle 1 is referred to as the X direction, the vehicle width direction of the vehicle 1 is referred to as the Y direction, and the vehicle height direction of the vehicle 1 is referred to as the Z direction.

(Outline of door control device)
As shown in FIG. 4, the door control device 10 includes a detection sensor (detection unit) 12, a door drive unit 21, an LED (display unit) 22, a collation unit 25, and a control unit 27. However, in FIG. 4, the part surrounded by the alternate long and short dash line is the configuration added this time, and the existing components mounted on the vehicle 1 are used for the door drive unit 21 and the comparison unit 25.

  In the door control device 10, when opening and closing the door 5 with respect to the vehicle body 2, the user performs, for example, the following defined movement in front of the door 5. As shown in FIGS. 1 and 2, the user moves inward in the Y direction so as to approach the door 5 of the vehicle 1 (first operation M1), and then outwards in the Y direction so as to separate from the door 5 Move (second operation M2). The control unit 27 detects the movement determined by the user based on the change in the distance obtained from the detection result of the detection sensor 12, whereby the door 5 is closed by the door drive unit 21. , And close the door 5 if the door 5 is open. Thereby, the user can automatically open and close the door 5 without using a hand.

  As shown in FIGS. 1 and 2, the detection sensor 12 detects an object to be detected located within a predetermined detection range 17 around the door 5. The detected object includes the user who holds the key (portable device), the third party other than the user, the obstacle, and the ground G. The obstacles include structures (walls and columns) existing around the vehicle, and vehicles parked next to the vehicle.

  As shown in FIG. 4, the detection sensor 12 is communicably connected to the control unit 27 by a communication cable. However, the detection sensor 12 may be communicably connected to an ECU (Electronic Control Unit) of the vehicle 1, and the control unit 27 may receive the detection result of the detection sensor 12 from the ECU. The detection sensor 12 may be wirelessly connected to the control unit 27 or the ECU.

  As the detection sensor 12, an ultrasonic sensor including a transmitter 13 and a receiver 14 is used. Referring to FIGS. 1 and 2, ultrasonic waves emitted from the transmitter 13 form a detection area 17 which spreads in a substantially conical shape along a defined direction. The reflected wave of the ultrasonic wave transmitted from the transmitter 13 is received by the receiver 14. The detection result is used to determine the presence or absence of an object in the detection range 17 and to calculate the distance from the detection sensor 12 to the object. The arrangement of the detection sensor 12 will be described in detail later.

  The door drive unit 21 drives the door 5 to open and close the vehicle body 2. Although not shown, the door drive unit 21 is configured by a motor, a gear mechanism, etc. for moving the door 5 forward in the X direction backward that opens the door 5 and in the X direction forward that closes the door 5. There is. The door drive unit 21 is communicably connected to the control unit 27 by a communication cable. However, the door drive unit 21 may be electrically connected to the ECU, and the control unit 27 may transmit the drive signal of the door drive unit 21 by the control unit 27 to the ECU, and the ECU may transmit to the door drive unit 21.

  The LED 22 provides an optical display for guiding the user. Referring to FIG. 3, the LED 22 is disposed on the vehicle body 2 so as to be located below the door 5 to be controlled. The LED 22 is mounted on a substrate in a casing, although not shown in detail. The substrate is communicably connected to the control unit 27 by a communication cable. The light of the LED 22 is configured to be able to be irradiated with an illuminance that can be viewed by the user even when the surroundings of the vehicle 1 are dark as well as when it is bright.

  The collation unit 25 includes a transceiver having an out-of-vehicle LF transmission / reception antenna that communicates with a key and an LF (Low Frequency) signal and performs authentication of the out-of-vehicle key. The transceiver is communicably connected to the control unit 27 by a communication cable, but may be communicably connected to the ECU. The transceiver is activated in response to an instruction from the ECU, and performs communication regarding key authentication processing. In the key authentication process, the collation means 25 sends a request for transmission of an authentication code to the key, compares the authentication code received from the key with the registered regular code, and is a user if they match (establish) I will judge.

  The control unit 27 controls the door drive unit 21 based on the result of the key authentication by the collation unit 25 and the detection result of the detection sensor 12. The control unit 27 includes a storage unit 28, a measurement unit 29, a determination unit 30, and a display drive unit 31, and is communicably connected to the ECU. The control unit 27 is configured of a single or a plurality of microcomputers and other electronic devices.

  The storage unit 28 stores a control program, setting data such as a threshold used in the control program and the determination value D, and a data table for calculating a distance from the detection result of the detection sensor 12. Further, the storage unit 28 is configured to be able to store the detection result of the detection sensor 12 for the set number of times (for example, 10 times).

  The measurement unit 29 detects the detection object from the detection sensor 12 based on the time (detection result) from when the transmitter 13 transmits (radiates) ultrasonic waves to when the receiver 14 receives reflected waves. Measure the distance to the object. That is, the measuring unit 29 and the detection sensor 12 constitute a distance measurement sensor that measures the distance from the detection sensor 12 to the object to be detected. The measurement result is stored in the storage unit 28 as distance information. When the storage unit 28 exceeds the settable number of times that can be stored, the measurement results are erased in order from the oldest one.

  The judging unit 30 judges the movement of the object to be detected based on the change of the distance which is the measurement result (the position of the object to be detected) of the measuring unit 29. That is, the determination unit 30 determines whether the object to be detected has moved or stopped based on the difference (change amount) between the current measurement result and the previous measurement result. If the amount of change is large, the movement distance is large, and if the amount of change is small, the movement distance is small. The determination unit 30 determines that the object to be detected has moved if the amount of change exceeds a predetermined determination value D, and determines that the object to be detected is stopped if the amount of change is less than the determination value D.

  The display driving unit 31 switches the LED 22 to the lighting state, the blinking state, and the extinguishing state. For example, when the determination unit 30 determines that the user has entered the detection range 17 and the key authentication by the comparison unit 25 is established, the display drive unit 31 switches the LED 22 from the off state to the on state. In addition, when the determination unit 30 determines that the user has performed the determined movement, the display drive unit 31 causes the LED 22 to blink. Then, when the open drive or close drive of the door 5 by the door drive unit 21 is completed, the display drive unit 31 turns off the LED 22. As described above, the user can understand the detection state by the detection sensor 12 to improve the operability by the user. Note that the circular mark 23 (see FIGS. 8 and 10) is displayed on the ground G and the detection position of the detection sensor 12 is displayed as in the second embodiment to be described later, instead of visually recognizing the lighting state of the LED 22. You may make it visually recognize.

(Placement of detection sensor)
As shown most clearly in FIG. 1, the detection sensor 12 is fixed to the bottom 3 of the vehicle body 2. The detection sensor 12 is disposed on the side 4 opposite to the door 5 in the Y direction such that the detection sensor 12 is positioned at a predetermined interval in the Y direction with respect to the door 5 to be controlled. This interval is a distance required to detect the movement of the user by the detection sensor 12, and is preferably set to 60 cm or more. Further, the detection sensor 12 is disposed so as to form a detection range 17 extending along the horizontal direction (horizontal line H) from the detection sensor 12 toward the door 5 to be controlled.

  Referring to FIG. 5, the detection sensor 12 is disposed in the casing 15 and configured such that the output of the transmitter 13 and the input of the receiver 14 are located on the same plane of the casing 15. A horn 16 for enhancing the directivity of the ultrasonic wave transmitted by the transmitter 13 is disposed on one surface of the casing 15 on which the output unit and the input unit are located. The horn 16 is formed in a conical cylinder shape having a first opening 16a surrounding the output of the transmitter 13 and the input of the receiver 14, and a second opening 16b having a diameter larger than the first opening 16a. There is.

(Setting of detection range)
The radiation angles R1 and R2, the maximum length L, and the inclination angle i of the detection range 17 are as follows in order to reliably detect a user by the detection sensor 12 and to suppress false detections other than the user. It is set to.

  As shown in FIGS. 1 and 2, the detection range 17 of the detection sensor 12 is wider in the X direction in the bottom view (XY plane) than in the Z direction in the rear view (YZ plane). It is set to be fan-shaped. That is, the detection range 17 is set such that the radiation angle R1 in the rear view shown in FIG. 1 is smaller than the radiation angle R2 in the bottom view shown in FIG.

  If the radiation angle R1 in the rear view is too narrow, detection of the user by the detection sensor 12 becomes difficult, and if too wide, the bottom 3 of the vehicle body 2 and the ground G are detected by the detection sensor 12, which is not preferable. In order to prevent these problems, it is preferable to set the radiation angle R1 as large as possible without detecting the bottom 3 of the vehicle body 2 and the ground G. If the radiation angle R2 in the bottom view is too narrow, detection of the user by the detection sensor 12 becomes difficult, and if too wide, the possibility of false detection of the tire of a third party or vehicle 1 by the detection sensor 12 increases. Unfavorable. In order to prevent these disadvantages, the radiation angle R2 is preferably set so that the width in the X direction of the tip 17a is substantially the same as the width in the X direction of the door 5.

  If the maximum length L of the detection range 17 from the detection sensor 12 to the tip 17a is too short, detection of the user by the detection sensor 12 becomes difficult, and if too long, the vehicle parked next by the detection sensor 12 It is not preferable because the possibility of false detection is high. In order to prevent these disadvantages, the maximum length L of the detection range 17 is set to a dimension that protrudes outward from the side surface 4 of the vehicle body in a bottom view and is shorter than the distance to the next adjacent vehicle. It is done.

  As shown in FIG. 1, the inclination angle i in the rear view is defined as an angle formed by the horizontal line H extending in the Y direction through the detection sensor 12 and the output center C of the detection range 17. The upper edge 17b of the detection range 17 is located on the bottom 3 side of the vehicle body 2, and the lower edge 17c of the detection range 17 is located on the ground G side. The inclination angle i is not preferable because the bottom 3 of the vehicle body 2 enters the detection range 17 when the inclination angle i is excessively narrowed, and the ground G enters the detection range 17 when the inclination angle i is excessively wide. In order to prevent these disadvantages, the inclination angle i is set to a half of the radiation angle R1.

  The inclination angle i of the detection range 17 in this embodiment is set to an inclination that the output center C passes through the approximate center between the bottom 3 of the vehicle body 2 and the ground G on the side 4 where the door 5 to be controlled is disposed. ing. Further, the radiation angle R1 of the detection range 17 is set to a size such that the upper edge 17b coincides with the horizontal line H. The maximum length L of the detection range 17 is set to be shorter than the dimension at which the lower edge 17 c intersects the ground G.

  As shown in FIG. 2, the output center C of the detection range 17 in a bottom view is configured to coincide with the Y direction in the present embodiment. However, the output center C of the detection range 17 may be inclined at a predetermined angle with respect to a horizontal line H extending in the Y direction through the detection sensor 12.

  The detection range 17 set in this manner passes between the bottom 3 of the vehicle body 2 and the ground G along the horizontal direction (horizontal line H) and extends from the inside (lower side) to the outside of the vehicle body 2 in bottom view. It extends. Further, the detection range 17 is inclined downward at an inclination angle i at which the bottom 3 of the vehicle body 2 and the ground G are not detected.

  Since the detection sensor 12 is disposed on the bottom 3 of the vehicle body 2, mounting the door control device 10 does not affect the design of the vehicle 1. Further, since the detection sensor 12 is disposed at an interval in the Y direction with respect to the door 5, even if the side surface 4 of the vehicle 1 has a small space around, the distance necessary for detection can be secured.

  Since the detection range 17 has a flat shape in which the dimension in the bottom view (XY plane) is larger than the dimension in the rear view (YZ plane), the detection sensor 12 suppresses erroneous detection of the bottom 3 or the ground G of the vehicle body 2 it can. In addition, the arrangement of the horn 16 effectively narrows the detection range 17 of the detection sensor 12. Moreover, the maximum length L of the detection range 17 can be easily set so that the detection sensor 12 does not erroneously detect the adjacent vehicle. Therefore, the malfunctioning of the door 5 accompanying the misdetection by the detection sensor 12 can be suppressed.

(Control by control unit)
The automatic opening / closing control of the door 5 by the control unit 27 is started when the vehicle 1 is parked and the engine is stopped. When the control unit 27 determines that the key authentication by the collation unit 25 is established and the user has performed the determined movement within the detection range 17, the door drive unit 21 opens or closes the door 5.

  The detection range 17 of the detection sensor 12 is divided into a trigger section 18 and a start section 19 according to the difference in distance from the detection sensor 12. The trigger section 18 is apart from the detection sensor 12 and extends from a first setting distance located below the vehicle body 2 to a second setting position further away from the detection sensor 12 than the first setting position and located near the door 5. In between, it is set. The start section 19 is set from the second set distance to a third set distance which is farther from the detection sensor 12 than the second set position and spaced apart from the door 5 to the outside.

  The movement of the user determined by the determination unit 30 includes the movement between the trigger section 18 and the start section 19. That is, a first operation M1 of moving from the start section 19 to the trigger section 18 to approach the door 5 and a second operation M2 of moving from the trigger section 18 to the start section 19 so as to be away from the door 5 are included. ing. The movement for controlling the door 5 is not limited to this, and an operation of stopping for a predetermined time may be added between the operations M1 and M2, and can be changed as necessary.

  Thus, by setting the movement by the user as movement across the two operation sections 18 and 19, the movement of the third party existing around the vehicle 1 matches the defined movement. The possibility of doing so can be reduced. Therefore, the erroneous operation of the door 5 due to the erroneous detection of the detection sensor 12 can be reduced. Also, the user only needs to move toward and / or away from the door 5. That is, in order to drive the door 5 to open and close, it is not necessary for the user to be in an unstable one-foot standing posture, so that the stability and operability of the user at the time of operation can be improved.

  Next, the operation of the door control device 10 will be described according to the flowcharts shown in FIGS. 6A and 6B.

  As shown in FIG. 6A, the control unit 27 first waits until a predetermined detection time has elapsed (step S1). When the detection time has elapsed, the control unit 27 causes the transmitter 13 to transmit the ultrasonic wave and causes the receiver 14 to receive the reflected wave (step S2).

  When the detection sensor 12 does not detect the detected object (step S3: No), the control unit 27 causes the display driving unit 31 to switch the LED 22 to the light-off state and clears the key authentication state (step S4).

  When the detection sensor 12 detects the detected object (step S3: Yes), it is read whether or not the key authentication is established (step S5). Then, when the key authentication is not established (step S5: No), the control unit 27 requests the key authentication (step S6). In the authentication process, the collation means 25 requests the key to transmit an authentication code, compares the authentication code received from the key with the registered regular code, and determines that the user is the user if they match.

  When the key authentication is not established (step S7: No), the control unit 27 turns off the LED 22 and clears the key authentication state (step S4). When the key authentication is established (step S7: Yes), the control unit 27 switches the LED 22 to the lighting state by the display driving unit 31 as shown in FIG. 6B (step S8).

  When the key authentication is established (steps S5 and S7: Yes), the control unit 27 determines the movement of the user based on the measurement result (step S9).

  If the change in the distance obtained by the detection result of the detection sensor 12 does not match the determined movement (step S10: No), the process waits for the next detection time.

  When the change in the distance obtained by the detection result of the detection sensor 12 matches the defined movement (step S10: Yes), the control unit 27 detects whether the door 5 is in the closed state or in the open state. . When the door 5 is in the closed state (step S11: Yes), the control unit 27 performs a door open output for opening the door 5 by the door drive unit 21 (step S12). When the door 5 is in the open state (step S11: No), the control unit 27 performs a door close output for closing the door 5 by the door drive unit 21 (step S13).

  Subsequently, the control unit 27 switches the LED 22 to the blinking state (step S14), and stands by until the open drive or close drive by the door drive unit 21 is completed (step S15). Then, when the driving of the door drive unit 21 is completed, the control unit 27 turns off the LED 22, clears the key authentication state (step S16), and stands by for the next detection time.

  As described above, in the door control device 10 according to the present embodiment, since the detection sensor 12 is disposed at an interval from the door 5, even the side 4 with a small space around it is necessary for detection. The distance can be secured. Further, the control unit 27 improves the stability and operability of the user at the time of driving the door 5 because the movement determined by the user is detected by the change of the distance obtained from the detection result of the detection sensor 12. it can.

Second Embodiment
FIGS. 7 to 9 show a vehicle door control device 10 according to a second embodiment mounted on a vehicle 1. The door control device 10 is mounted on a vehicle 1 in which electrically driven side doors 5A and 5B are respectively disposed on a pair of side surfaces 4 formed to face in the Y direction of the vehicle body 2.

  As shown in FIG. 9, the door control device 10 includes two detection sensors 12A and 12B, two door drive units 21A and 21B, two LEDs 22A and 22B, a collating means 25 similar to the first embodiment, And a control unit 27.

  As shown in FIGS. 7 and 8, the first detection sensor 12A detects an object to be detected around the left side door (first side door) 5A positioned on the upper side in FIG. It is arrange | positioned at the bottom 3 of the vehicle body 2 so that it may be located in the right side door (2nd side door) 5B side located in the side. The second detection sensor 12B detects an object to be detected around the right side door 5B, and is disposed on the bottom 3 of the vehicle body 2 so as to be located on the left side door 5A side. As shown in FIG. 9, as the detection sensors 12A and 12B, as in the first embodiment, ultrasonic sensors including a transmitter 13 and a receiver 14 are respectively used, and are communicably connected to the control unit 27. ing.

  The first door driver 21A is for opening and closing the left side door 5A with respect to the vehicle body 2, and the second door driver 21B is for opening and closing the right side door 5B with respect to the vehicle body 2. It is communicably connected to the unit 27.

  As shown in FIGS. 9 and 10, the first LED 22A is driven by the detection of the user by the first detection sensor 12A, and is disposed in the casing 15 of the second detection sensor 12B. The second LED 22B is driven by the detection of the user by the second detection sensor 12B, and is disposed in the casing 15 of the first detection sensor 12A. Thus, since LED22B, 22A is integrally attached to the casing 15 of detection sensor 12A, 12B, the attachment workability | operativity to the vehicle 1 can be improved.

  The LEDs 22A and 22B are communicably connected to the control unit 27, and illuminate the ground G in the detection range 17 when the detection sensors 12A and 12B detect a user. In the present embodiment, the circular marks 23 (see FIGS. 8 and 10) are displayed on the ground G by lighting or blinking of the LEDs 22A and 22B, and the visibility of the user is improved. Also, the LEDs 22A and 22B may be welcome lights. In this case, when the doors 5A and 5B are unlocked after the key authentication is established, and / or lighted during opening and closing of the doors 5A and 5B, display is performed to indicate the positions of the doors 5A and 5B being driven. As described above, characters and patterns may be displayed as needed instead of the circular marks.

  The detection sensors 12A and 12B including the LEDs 22B and 22A are disposed on the bottom 3 of the vehicle body 2 so that the individual detection ranges 17 are set in the same manner as in the first embodiment.

  The control unit 27 includes a first unit including a first detection sensor 12A, a first LED 22A, and a first door drive unit 21A, and a second unit including a second detection sensor 12B, a second LED 22B, and a second door drive unit 21B. Is different from the first embodiment in that it is selectively driven. Specifically, the control unit 27 drives both of the two detection sensors 12A and 12B until the user who has the key is detected. When the user who possesses the key is detected, the control unit 27 drives only a unit including one of the two detection sensors 12A and 12B that detects the user.

  Specifically, when the detection target is detected by the first detection sensor 12A and the authentication by the collation unit 25 is established, the control unit 27 then controls the first detection sensor 12A, the first LED 22A, and the first door drive unit 21A. Drive only. That is, the control unit 27 does not perform the detection by the second detection sensor 12B and the display by the second LED 22B, as well as the driving of the second door drive unit 21B. In addition, when the second detection sensor 12B detects an object to be detected and the authentication by the collation unit 25 is established, the control unit 27 drives only the second unit and does not drive the first unit.

  Next, the operation of the door control device 10 of the second embodiment will be described according to the flowcharts shown in FIGS. 11A and 11B.

  As shown in FIG. 11A, the control unit 27 stands by until a predetermined detection time elapses (step S20), and when the detection time elapses, the control unit 27 transmits ultrasonic waves from the transmitter 13 and receives the receiver. The reflected wave is received by step S14 (step S21). At this time, of the two detection sensors 12A and 12B, only one set in step S24 or step S39 described later or only one set in step S28 is driven.

  When the detection sensors 12A and 12B do not detect the detected object (step S22: No), the control unit 27 causes the display drive unit 31 to switch the LEDs 22A and 22B into the extinguished state and clears the key authentication state (step S23). . Further, the drive setting is changed so that the two detection sensors 12A and 12B are driven thereafter (step S24).

  When the detection sensor 12A or 12B detects the detected object (step S22: Yes), it is read whether or not the key authentication is established (step S25). Then, when the key authentication is not established (step S25: No), the control unit 27 requests the key authentication (step S26).

  When the key authentication is not established (step S27: No), the control unit 27 turns off the LEDs 22A and 22B and clears the key authentication state (step S23). Further, the drive setting is changed so that the two detection sensors 12A and 12B are driven thereafter (step S24).

  When the key authentication is established (step S27: Yes), the control unit 27 changes the drive setting so that only one of the two detection sensors 12A and 12B that detects the user is driven (step S28). ). Further, the drive setting is changed such that only one of the two LEDs 22A and 22B corresponding to the detection sensor 12A or 12B to be driven is driven (step S29). For example, when the detection sensor 12A is driven, the LED 22A disposed on the detection sensor 12B is set to be driven, and when the detection sensor 12B is driven, the LED 22B disposed on the detection sensor 12A is set to be driven. Do. After that, as shown in FIG. 11B, the display driving unit 31 switches the LED 22A or 22B to be driven to the lighting state (step S30).

  When the key authentication is established (steps S25 and S27: Yes), the control unit 27 determines the movement of the user based on the measurement result (step S31).

  If the change in the distance obtained by the detection result of the detection sensor 12A or 12B does not match the defined movement (step S32: No), the process waits for the next detection time.

  If the change in the distance obtained by the detection result of the detection sensor 12A or 12B matches the defined movement (step S32: Yes), the control unit 27 determines whether the corresponding door 5A or 5B is in the closed state or in the open state To detect When the door 5A or 5B is in the closed state (step S33: Yes), the control unit 27 performs a door open output for opening the door 5A or 5B by the door drive unit 21A or 21B (step S34). When the door 5A or 5B is in the open state (step S33: No), the control unit 27 performs door closing output for closing the door 5A or 5B by the door drive unit 21A or 21B (step S35).

  Subsequently, the control unit 27 switches the LED 22A or 22B to the blinking state (step S36), and stands by until the open drive or close drive by the door drive unit 21A or 21B is completed (step S37). When driving of the door drive unit 21A or 21B is completed, the control unit 27 turns off the LED 22A or 22B and clears the key authentication state (step S38). Further, the drive setting is changed so that the two detection sensors 12A and 12B are driven thereafter (step S39), and the process waits for the next detection time.

  As described above, in the door control device 10 according to the second embodiment, the first unit including the first detection sensor 12A, the first LED 22A, and the first door drive unit 21A, the second detection sensor 12B, the second LED 22B, and the second unit Since it is equipped with the 2nd unit which consists of 2 door drive part 21B, it can respond to vehicles 1 of double-sided side door 5A, 5B. Moreover, since only one of the two detection sensors 12A and 12B that has detected the user is driven, it is possible to suppress false detection by a third party other than the user. Furthermore, since the LEDs 22A and 22B are disposed in the casing 15 of the detection sensors 12A and 12B, respectively, and the other LED can be used when one of the detection sensors is being driven, it is possible to provide the detection sensor and the LEDs separately. The number of parts can be reduced.

  Further, as in the first embodiment, even at the side portion of the vehicle 1 with a small space around it, the distance necessary for detection can be secured, and therefore, the stability of the user when driving the doors 5A, 5B. Operability can be improved.

  In addition, the vehicle door control apparatus 10 of this invention is not limited to the structure of the said embodiment, A various change is possible.

  For example, as shown in FIG. 7, in a vehicle 1 equipped with a back sonar that monitors the rear during traveling, two or more (four in the drawing) back sonar sensors (ultrasonic sensors) 33A to 33D are used. The unit to be driven by the control unit 26 may be set. That is, based on the order in which the back sonar sensors 33A to 33D arranged at intervals in the Y direction of the vehicle body 2 detect the detection object, the control unit 26 determines which direction the user is moving in the left or right direction. Do. Then, the control unit 26 may drive the detection sensor 12A or 12B corresponding to the door 5A or 5B in which the user moves, and the LED 22A or 22B.

  As shown in FIG. 12, the detection sensor 12 may be disposed at the center of the bottom 3 of the vehicle body 2 in the Y direction. Further, at the center of the bottom 3 of the vehicle body 2, a detection sensor 12A for the left side door 5A and a detection sensor 12B for the right side door 5B may be disposed. In this case, the LEDs 22A and 22B are preferably disposed below the side doors 5A and 5B of the vehicle body 2, as in the first embodiment.

  The detection sensor 12 may be configured by an infrared sensor including a light emitting element and a light receiving element. When an infrared sensor is used as the detection sensor 12, the directivity of the detection range can be enhanced without using the horn 16 shown in FIG. Therefore, the operation failure of the door 5 due to the erroneous detection of the detection sensor 12 can be effectively suppressed. Further, the sensor is not limited to the ultrasonic sensor or the infrared sensor, and any sensor that can detect the detected object and can determine the distance to the detected object based on the detection result can be changed as needed.

  The detection sensor 12 arranges the detection sensor 12 at the center between the bottom 3 of the vehicle body 2 and the ground G so that the inclination angle i becomes 0 degree (horizontal), and outputs the output center C of the detection range 17 and the horizontal line H May be matched. The detection range 17 of the detection sensor 12 may be set only between the bottom 3 of the vehicle body 2 and the ground G so as not to protrude outward from the vehicle body 2 in bottom view.

  The control unit 27 may divide the detection range 17 into three or more operation sections to detect the movement set by the user. Further, the movement to be determined may be set by combining the change in distance (movement), the stop, the number of movements, and the number of stops as necessary. Further, the movement to be defined may be configured by a combination of approach and stop without dividing the detection range 17 into two or more operation sections.

  The electric device of the door 5 is not limited to the door drive unit 21 that drives the door 5 to open and close, and may be a door lock device that locks the door 5 to the vehicle body 2 so as not to be opened. Moreover, the door to be controlled is not limited to the side door, but may be a back door.

  The detection range 17 of the detection sensor 12 may be a maximum length L including a vehicle parked next. In this case, the control unit 27 (judging unit 30) determines that the detected object having no change in the distance (position) for a predetermined time or more is an obstacle, and the measurement result is not used to detect the movement of the user. It is preferable to set it as a structure.
