Abstract

PROBLEM TO BE SOLVED: To mitigate anxiety about a user being hurt by an unexpected opening motion.SOLUTION: An opening motion of a power slide door 22 is executed, when a user performs a kick motion in the vicinity of the power slide door 22 and the height of a portable apparatus 24 is larger than a reference value. In other words, the opening motion is inhibited in the case that the height of the portable apparatus 24 is equal to or smaller than the reference value even when the user performs a motion similar to the kick motion in the vicinity of the power slide door 22. A supposed motion similar to the kick motion is a motion of inserting an arm into a gap between an outer bottom surface of a vehicle and the ground.SELECTED DRAWING: Figure 2

Description

  The present invention relates to a power slide door control device, and more particularly to a power slide door control device that executes an opening operation of a power slide door when a user's movement in the vicinity of the power slide door matches a predetermined condition.

  Generally, when opening a trunk, there are means such as unlocking with a mechanical key, pressing a button on a keyless / key-free portable machine, etc., but these operations are difficult if the user is clogged with a load etc. It is. In order to solve such a difficulty, there is a technique for opening a trunk by performing a kick operation with one foot in a vehicle gap below the trunk portion.

  For example, Patent Document 1 discloses a technique for automatically opening a back door when a luggage is put into a trunk of a vehicle.

JP 2005-324675 A

  However, when the technique of opening the trunk by kick operation is used to open and close the power slide door on the side of the vehicle, the following problems occur. In other words, since the sensor that detects the user's kick operation is non-contact type, the detection target is not limited to the user's foot, and as a result, the movement of grass growing on the ground or the animal running through the vehicle gap is erroneously detected as a kick operation. May be.

  Although this erroneous detection can be reduced by mounting a plurality of sensors, it is difficult to completely eliminate the erroneous detection. For example, if the user inserts a hand near the sensor next to the power slide door (such as picking up a falling object), this movement is similar to a kick operation with one foot, and the power slide door can be opened. There is sex. When the user is crouching in front of the power slide door, the door body lifted in the vehicle side direction by the opening operation may come into contact with the user's head, and the user may be injured.

  Therefore, a main object of the present invention is to provide a power sliding door control device that can reduce a user's fear of injury due to an unexpected opening operation.

  A power slide door control device according to a first aspect of the present invention is a power slide door control device that executes an opening operation of the power slide door when the movement of the portable device holder in the vicinity of the power slide door meets a predetermined condition. In addition, a detection unit that detects the height of the portable device prior to the opening operation, and a prohibiting unit that prohibits the opening operation when the height detected by the detection unit is equal to or less than a reference.

  The power slide door control device according to the second aspect of the invention is a power slide door that is operated together with a buzzer sounding when a request switch is operated or when a user's movement in the vicinity of the power slide door matches a predetermined condition. The power sliding door control device that executes the opening operation of the opening operation, the execution timing of the opening operation when the trigger matches the predetermined condition is delayed from the execution timing of the opening operation when the trigger is an operation of the request switch This is a power slide door control device.

  According to the first invention, even if the movement of the portable device holder (user) in the vicinity of the power slide door matches the predetermined condition, if the height of the portable device is below the reference, the power slide door Opening operation is prohibited. As a result, it is possible to reduce the concern that the user may be injured due to an unexpected opening operation.

  According to the second invention, the opening operation of the power slide door is executed together with the buzzer. However, the execution timing of the opening operation differs depending on whether the trigger of the opening operation is a user movement that matches a predetermined condition or a request switch operation. That is, the opening operation when the trigger is the former is executed later than the opening operation when the trigger is the latter. As a result, it is possible to reduce the concern that the user may be injured due to an unexpected opening operation.

  The above object, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

[Example 1]
With reference to FIG. 1 (A), FIG. 1 (B), and FIG. 2, the power slide door control device 10 of this embodiment forms part of a key-free system and controls the opening operation of the power slide door 22. And is formed by the transmitters 12L, 12R, 12B, 14F, 14B, the request switch 16, the kick sensor 18, and the key-free ECU 20.

  Among these, the transmitter 12L is provided on the left door mirror, the transmitter 12R is provided on the right door mirror, and the transmitter 12B is provided on the back door. The transmitter 14F is provided on the instrument panel at the front of the passenger compartment, and the transmitter 14B is provided on the rear seat of the passenger compartment. Further, the kick sensor 18 is provided in the vicinity of the power slide door 22 on the outer bottom surface of the vehicle 100, and the request switch 16 is provided on the door lever of the power slide door 22.

  The transmitters 12L, 12R, 12B, 14F, and 14B are devices that perform communication with the portable device 24 possessed by the user. When receiving the radio waves transmitted from each of the transmitters 12L, 12R, 12B, 14F, and 14B, the portable device 24 distances each of the transmitters 12L, 12R, 12B, 14F, and 14B based on the reception intensity of the radio waves. And the distance information indicating the calculated distance and its own ID are transmitted. For convenience of explanation, identification numbers “1” to “5” are assigned to the transmitters 12L, 12R, 12B, 14F, and 14B in this order.

  The request switch 16 is turned on when the user holds the door lever, and turned off when the user releases the door lever. The kick sensor 18 is specifically an electrostatic sensor, and detects the movement of an object between the outer bottom surface of the vehicle 100 and the ground.

  The key-free ECU 20 considers that a PSD opening request has been issued when the request switch 16 is turned on, or when the movement detected by the kick sensor 18 corresponds to the kick operation of the user. Then, key free ECU20 acquires distance information and ID from portable machine 24 via each of transmitter 12L, 12R, 12B, 14F, and 14B.

  When the acquired ID matches the registered ID, the key-free ECU 20 determines whether the power sliding door 22 has a different condition depending on whether the trigger for the PSD opening request is an ON operation of the request switch 16 or a detection output of the kick sensor 18. Perform opening operation.

  That is, if the trigger of the PSD opening request is an ON operation of the request switch 16, the user's intention to open the power sliding door is clear, and therefore the power sliding door 22 is independent of the distance information acquired from the portable device 24. Opening operation is performed.

  On the other hand, if the PSD opening request trigger is the detection output of the kick sensor 18, an operation different from the kick operation (for example, an operation of inserting an arm between the outer bottom surface of the vehicle 100 and the ground) may be erroneously detected as the kick operation. Therefore, the height of the portable device 24 is calculated based on the distance information acquired from the portable device 24.

  If the calculated height exceeds the reference value REF, the detection output of the kick sensor 18 is regarded as a kick operation by the user, and the power slide door 22 is opened. On the other hand, if the calculated height is less than or equal to the reference value REF, the output of the kick sensor 18 is regarded as an operation other than the kick operation, and the opening operation of the power slide door 22 is prohibited.

  The key-free ECU 20 executes processing according to the flowcharts shown in FIGS. The control program corresponding to this flowchart is stored in the memory 20m.

  First, the state of the request switch 16 is identified in step S1, and the output of the kick sensor 18 is acquired in step S3. In step S5, it is determined whether a PSD opening request has been issued based on the identification result in step S1 and the output acquired in step S3. The determination result is YES when the request switch 16 indicates the ON state or when the output of the kick sensor 18 indicates the user's kick operation. The determination result is also NO when the request switch 16 indicates an off state and the output of the kick sensor 18 indicates an operation (including no movement) different from the user's kick operation.

  If the determination result of step S5 is NO, it will return to step S1, and if the determination result of step S5 is YES, it will progress to step S7. In step S 7, communication is performed with the portable device 24 according to the subroutine shown in FIG. 4, and distance information indicating the distance from each of the transmitters 12 L, 12 R, 12 B, 14 F, 14 B to the portable device 24 and the portable information 24 are written. ID.

  In step S9, it is determined whether or not the ID acquired from the portable device 24 matches the ID registered in the memory 20m. If the determination result is NO, the process returns to step S1, while if the determination result is YES, the trigger for the PSD opening request is determined in step S11.

  If the trigger is an operation of the request switch 16, the power slide door 22 is opened in step S17, and then the process ends. On the other hand, if the trigger is a kick operation in the vicinity of the kick sensor 18, the process proceeds to step S13, and the height of the portable device 24 is calculated based on the distance information acquired in step S7.

  In step S15, it is determined whether or not the calculated height exceeds the reference value REF. If the determination result is NO, the process returns to step S1, and if the determination result is YES, the power slide door 22 is opened in step S17, and then the process ends. Therefore, if the height of the portable device 24 is equal to or less than the reference value REF, the opening operation of the power slide door 22 is prohibited.

  In the subroutine shown in FIG. 4, first, the variable K is set to “1” in step S21, and radio waves are transmitted from the Kth transmitter in step S23. The portable device 24 that has received this radio wave calculates the distance to the Kth transmitter based on the intensity of the received radio wave, and transmits distance information indicating the calculated distance to the Kth transmitter along with its own ID.

  In step S25, it is determined whether or not the reception from the portable device 24 is successful. If the determination result is NO, the process proceeds to step S29 as it is. If the determination result is YES, the received distance information and ID are stored in the memory 20m. After temporarily saving, the process proceeds to step S29. In step S29, it is determined whether or not the variable K has reached “5”. If the determination result is NO, the variable K is incremented in step S31 and then the process returns to step S23. If the determination result is YES, the process returns to the upper layer routine.

As can be understood from the above description, the opening operation of the power slide door 22 is performed when the movement in the vicinity of the power slide door 22 corresponds to the kick operation of the user and the height of the portable device 24 exceeds the reference value REF. Executed. In other words, even if the user performs an operation similar to the kick operation in the vicinity of the power slide door 22 (for example, an operation of inserting an arm between the outer bottom surface of the vehicle 100 and the ground), the portable device 24 at this time If the height is less than or equal to the reference value REF, the opening operation is prohibited. As a result, it is possible to reduce the concern that the user may be injured in the head, for example, due to the unexpected opening operation.
[Example 2]

  In the power slide door control device 10 of another embodiment, a buzzer (not shown) is added, and the key-free ECU 20 executes a process according to the flowchart shown in FIG. 5 instead of the process according to the flowchart shown in FIGS. Since it is the same as the power slide door control apparatus 10 shown in FIG.

  Referring to FIG. 5, in steps S <b> 41 to S <b> 45, the same processing as steps S <b> 1 to 5 shown in FIG. 3 is executed. If the determination result in step S <b> 45 is YES, the ID is acquired from the portable device 24 by communication with the portable device 24. In step S49, it is determined whether or not the acquired ID matches the ID registered in the memory 20m. If the determination result is NO, the process returns to step S41. If the determination result is YES, the buzzer is sounded in step S51. Let

  In step S53, the trigger for the PSD opening request is determined as in step S11 shown in FIG. It is determined whether the trigger is an operation of the request switch 16 or a kick operation in the vicinity of the kick sensor 18. If the trigger is an operation of the request switch 16, the process directly proceeds to step S57 to open the power slide door 22. On the other hand, if the trigger is a kick operation in the vicinity of the kick sensor 18, the process waits for a predetermined time in step S55, and then proceeds to step S57, where the power slide door 22 is opened.

  Therefore, when the PSD opening request shown in FIG. 6A is issued with the operation of the request switch 16 as a trigger, the opening operation of the power slide door 22 is executed almost simultaneously with the buzzer sounding (FIG. 6B). FIG. 6 (C)). On the other hand, when the PSD opening request shown in FIG. 6A is issued with a kick operation in the vicinity of the kick sensor 18 as a trigger, the power slide door is opened after a predetermined time has elapsed since the start of the buzzer. 22 is performed (see FIGS. 6B and 6D).

  Similar to the first embodiment, if the PSD opening request trigger is the detection output of the kick sensor 18, an operation different from the kick operation (for example, an operation of inserting an arm between the outer bottom surface of the vehicle 100 and the ground) is erroneously detected as the kick operation. The possibility of being detected cannot be denied. Therefore, in this embodiment, the buzzer is sounded to notify the opening operation of the power slide door 22, and the opening operation is executed after that.

  The user is prompted to retreat from the vicinity of the power slide door 22 by the buzzer. As a result, the concern that the user may be injured in the head due to an unexpected opening operation can be reduced by a simpler method than in the first embodiment.

  In the first embodiment, it is not assumed that the buzzer is sounded. However, the buzzer may be sounded when the opening operation of the power slide door 22 is prohibited. Thereby, the user can know the reason why the power slide door 22 does not open.
