  By the way, as described above, in a vehicle in which the door is opened by operating the opener switch in the vehicle interior, it is not preferable that the door is opened during traveling. Therefore, even if the opener switch is operated during traveling, the door does not open. I am doing so. However, if the door is not opened when the opener switch is operated during driving, if you notice that it is a half-door after driving, you need to stop the vehicle, open the door, and then close the door. There is a lack of convenience.

  The vehicle door control device according to the present invention detects the opening / closing state of the vehicle door including the half door state by the door detection means, detects the vehicle speed by the vehicle speed detection means, and opens the vehicle door by the operation of the occupant by the operation command means. Is commanded, the opening / closing of the vehicle door is permitted or prohibited based on the detected opening / closing state of the vehicle door and the vehicle speed.

  According to the present invention, when the opening of the vehicle door is commanded by the occupant's operation, the opening or closing of the vehicle door is permitted or prohibited based on the opening / closing state of the vehicle door including the half door state and the vehicle speed. If the user notices that the door is a half-door after traveling, the half-door state can be eliminated at an early stage, and convenience is improved.

  FIG. 1 is a block diagram showing a configuration example of a control device according to an embodiment of the present invention, which is applied to a swing type vehicle door. This control device is configured by connecting a controller 10 to an in-vehicle opener switch 11, an out-of-vehicle opener switch 12, a door switch 13, a combination meter 14, and a release actuator 15. As will be described in detail below, in the control device according to the present embodiment, if the door 20 is in a half-door state and the vehicle speed is less than the predetermined value V2, the opener switch 11 can be operated even during traveling. The opening operation of the door 20 by operation is permitted.

  The in-car opener switch 11 is operated by a switch button (not shown) installed in the passenger compartment. This switch button is an alternative to the vehicle door handle used when opening the door 20 from the vehicle interior. When the in-car opener switch 11 is operated by the user, a door opening input signal of the operated door 20 is transmitted to the controller 10.

  The vehicle opener switch 12 is operated by a switch button (not shown) provided near the knob on the outer surface of each vehicle door. This switch button is an alternative to the outside door handle used when opening the door 20 from outside the vehicle. When the outside opener switch 12 is operated by the user, the door opening input signal of the operated door 20 is transmitted to the controller 10. To do.

  The door switch 13 is a switch provided in the latch mechanism of each door 20, and is turned off when the door 20 is fully latched, and is turned on when the door 20 is in any other state (latch release or half latch). Become. The door switch 13 is provided to detect the closed state (full latch) and the half door state (half latch) of the door 20, and the ON / OFF state of the door switch 13 can be read from the controller 10. .

  The combination meter 14 displays vehicle speed information detected by a vehicle speed sensor (not shown), and the vehicle speed information is output to the controller 10. In addition, the combination meter 13 is provided with a display lamp 16 for notifying whether or not the input of the opener switch 11 is permitted by turning on and off. When the display lamp 16 is turned on, the input permission state of the opener switch 11 is notified, and when the display lamp 16 is turned off, the input prohibited state of the opener switch 11 is notified.

  A release actuator 15 constituted by an electric motor or the like is provided in the latch mechanism of the door 20. The release actuator 15 controls the drive of the latch mechanism from the full latch to the latch release or from the half latch to the latch release based on a command from the controller 10. In the full latch state or the half latch state, the striker is engaged with the notch of the latch and the door 20 is closed. When the latch release state is established, the striker is detached from the notch, and at this time, the assist pin is moved to the door 20. By pushing, the door 20 opens toward the outside of the vehicle.

  FIG. 2 is a flowchart showing an example of processing executed by the controller 10 of the control device of FIG. This flowchart starts, for example, when the IGN switch is turned on, and is repeated every predetermined time.

  First, in step S101, it is determined whether or not the opener switch 11 has been operated, that is, whether or not the opener switch 11 has changed from OFF to ON. If step S101 is affirmed, the process proceeds to step S102, and it is determined whether or not the door 20 is a half-door by a signal from the door switch 13. If step S102 is negative, that is, if it is determined that the door 20 is closed (full latched) and the opener switch 11 is operated, the process proceeds to step S106.

  In step S106, the vehicle speed output from the combination meter 14 is read, and it is determined whether the vehicle speed is equal to or higher than a predetermined value V1. This is a process for determining whether or not an operation command for the opener switch 11 is permitted under the closed state of the door 20, and the predetermined value V1 is, for example, near 0, that is, whether or not the vehicle is running. Is set to such a value.

  If step S106 is negative, the process proceeds to step S107, where an input of an operation command for the opener switch 11 is permitted. As a result, a drive signal is output to the release actuator 15, and the door 20 is opened in a latch release state. Next, in step S108, the display lamp 16 is turned on to notify the occupant that the operation command for the opener switch 11 is permitted.

  On the other hand, if step S106 is affirmed, the process proceeds to step S104, and the input of the operation command for the opener switch 11 is ignored. As a result, a drive signal is not output to the release actuator 15, the full latch state is maintained, and the door 20 remains closed. Next, in step S105, the display lamp 16 is turned off to notify the occupant that the operation command for the opener switch 11 is prohibited.

  If it is determined in step S102 that the door is in the half door state based on a signal from the door switch 13, the process proceeds to step S103. In step S103, the vehicle speed output from the combination meter 14 is read, and it is determined whether the vehicle speed is equal to or higher than a predetermined value V2. This is a process for determining whether or not to permit the operation command of the opener switch 11 under the half door state of the door 20, and the predetermined value V2 is at least larger than the predetermined value V1, for example, the vehicle is slow. The value is set so as to determine whether or not the vehicle is running. If step S103 is affirmed, the process proceeds to step S104, and the operation command for the opener switch 11 is ignored. If step S103 is negative, the process proceeds to step S107, and an operation command for the opener switch 11 is permitted.

The operation of the control device according to the present embodiment is summarized as follows.
(1) Door closed state If the opener switch 11 is operated while the door 20 is in a closed state and the vehicle speed is greater than or equal to the predetermined value V1, the input of the switch 11 is ignored and the door 20 is kept closed. (Step S106 → Step S104). Therefore, even if the opener switch 11 is accidentally operated during traveling, the door 20 does not open. When the opener switch 11 is operated while the vehicle is stopped, the input of the switch 11 is permitted because the vehicle speed is smaller than the predetermined value V1, and the door 20 is opened (step S106 → step S107). As a result, the vehicle can be moved on and off by operating the switch 11 when the vehicle is stopped.

(2) Half-door state When the opener switch 11 is operated while the door 20 is in the half-door state and the vehicle speed is running at a predetermined value V2 or more, the input of the switch 11 is ignored and the door 20 is kept closed. (Step S103 → Step S104). Therefore, when the traveling speed is relatively high, the door 20 does not open even if the opener switch 11 is operated in order to cancel the half-door state. In this case, since the display lamp 16 is turned off (step S105), the occupant can recognize that the operation command for the opener switch 11 is prohibited.

  When the opener switch 11 is operated in a state where the traveling speed is lower than the predetermined value V2, the input of an operation command for the opener switch 11 is permitted, and the door is opened (step S103 → step S105). Therefore, when the user notices that the vehicle is in the half-door state during traveling, the half-door state can be canceled by opening the door 20 once and then closing it, without decelerating the vehicle to V1 or less. In this case, since the display lamp 16 is lit (step S108), the occupant can recognize that the operation command for the opener switch 11 is permitted.

According to the present embodiment, the following operational effects can be achieved.
(1) When the door 20 is in the closed state, an operation command for the opener switch 11 is permitted until the vehicle speed becomes equal to or higher than the predetermined value V1. Until now, the operation command of the opener switch 11 is permitted. Accordingly, it is not necessary to lower the vehicle speed to the predetermined value V1 in order to eliminate the half-door state, and the half-door state can be eliminated at an early stage, which increases convenience.
(2) If the opener switch 11 is operated when the door 20 is in the half-door state, it is considered that the occupant consciously operated the switch 11, but the opener switch 11 is operated when the door 40 is in the closed state. The switch 11 is likely to be erroneously operated, and when the door 20 is closed, the opening of the door 20 by the operation of the switch 11 is prohibited until the vehicle speed becomes less than the predetermined value V1 smaller than the predetermined value V2. As a result, undesired opening of the door 20 during traveling can be prevented.
(3) Since the display lamp 16 notifies whether or not the operation of the operation switch 11 is permitted, the occupant can easily recognize whether or not the operation switch 11 can be operated. Therefore, when the half-door state is canceled during traveling, the occupant can operate the opener switch 11 with good timing by seeing that the display lamp 16 is lit.

  In the above-described embodiment, the door switch 13 that is turned off when the latch is full is used to detect the closed state and the half-door state of the door 20, but the door detection means other than the door switch and the switch that are turned on when the half is latched. These may be detected by. Although the vehicle speed detection value from the vehicle speed sensor is taken in by the output from the combination meter 14, the configuration of the vehicle speed detection means is not limited to this. Although the opening of the vehicle door is commanded by operating the opener switch 11, the operation command means is not limited to this. Although the latch is released by the release actuator 15 to open the door 20, other door opening means may be used. If the opening of the door 20 is permitted or prohibited based on the opening / closing state of the door 20 and the vehicle speed, the processing in the controller 10 as the opening control means is not limited to the above.

  The opening of the door 20 by the operation of the opener switch 11 is notified by turning on the display lamp 16, and the opening of the door 20 is prohibited by turning off the display lamp 16. The configuration of the notification means is not limited to this. For example, the fact that the opening of the door 20 is prohibited may be notified by blinking of the display lamp 16 or may be notified using a display form other than the display lamp. You may make it alert | report that the opening of a door is permitted / prohibited only in the half door state.

  When the door 20 is in a closed state, the opening of the door 20 is prohibited when the vehicle speed is equal to or higher than V1 as the first predetermined value (opening of the door 20 is permitted when the vehicle speed is lower than V1). When the vehicle speed is V2 or more as the second predetermined value, the door 20 is prohibited from being opened (when the vehicle speed is less than V2, the door 20 is allowed to be opened), but when the door 20 is in the half-door state, the door 20 is in the closed state. As long as the opening of the door 20 by the operation command is permitted at a higher vehicle speed, the predetermined values V1 and V2 may be set to any value.

  Although the above embodiment is applied to a swing type vehicle door, it can be similarly applied to a slide type vehicle door. That is, the present invention is not limited to the vehicle door control device of the embodiment as long as the features and functions of the present invention can be realized. The above description is merely an example, and when interpreting the invention, there is no limitation or restriction on the correspondence between the items described in the embodiment and the items described in the claims.

It is a block diagram which shows the control structural example of the control apparatus of the vehicle door by embodiment of this invention. It is a flowchart explaining the processing operation in the controller of FIG.
