Description
Technical Field
The present invention relates to a vehicle door opening/closing device and a failure detection method for the vehicle door opening/closing device.
Background
Some vehicles such as automobiles are provided with a door opening/closing device that opens and closes a door formed in a vehicle body by a door or the like in response to a user operation. For example, in a Vehicle such as a small van or an SUV (Sport Utility Vehicle), a tailgate opening/closing device having a door and a tailgate for opening and closing the door is provided at a rear end portion of a Vehicle body, and a luggage room provided at the rear end portion of the Vehicle body is opened and closed by the tailgate opening/closing device.
Since the back door of such a back door opening and closing device is configured to be opened and closed in the vertical direction, it may not be easy for women, elderly people, and the like to perform the opening and closing operation. Therefore, there has been developed an electric tailgate opening and closing device configured to automatically open and close a tailgate using an electric motor as a drive source (see, for example, patent documents 1 and 2).
The electric tailgate opening and closing device drives a drive unit that drives opening and closing of the tailgate based on an operation state of an opening and closing switch by a user. Specifically, when the user turns on an open switch among the opening and closing switches, the back door is driven to the open state. On the contrary, when a user turns on a closing switch among the opening and closing switches, the back door is driven to a closed state.

Disclosure of Invention
Problems to be solved by the invention
However, the on-off switch subjected to the user operation described above sometimes gets stuck in an on state (i.e., short-circuited) due to a failure. If such a jam occurs, the following situation may occur: the open switch is turned on although the user does not operate the open switch, so that the back door is unexpectedly turned on, or the close switch is turned on although the user does not operate the close switch, so that the back door is unexpectedly turned off.
As one method for preventing such a situation in advance, there is a method in which: the time length of the on state of the open/close switch is monitored by a timer, and when the on state of the open/close switch continues for a predetermined time (that is, a timer time) or longer, it is determined that a failure has occurred due to the open/close switch being stuck. When it is determined that a failure has occurred, the operation of the on-off switch is disabled, and an alarm display indicating the failure is displayed.
However, in the method of detecting a failure of the on/off switch using the timer, it takes at least a time corresponding to the timer time until the determination as to whether or not the failure has occurred is completed, and as a result, the following disadvantages occur: before the back door can be electrically driven by the open/close switch, a waiting time corresponding to the timer time is generated. For example, if it is assumed that the detection of the malfunction of the open/close switch is started when the ignition switch is turned on, if the timer time is 5 seconds, the electric driving of the back door by the open/close switch cannot be performed until 5 seconds after the ignition switch is turned on.
The present invention has been made in view of the above problems, and provides a vehicle door opening/closing device and a failure detection method for a vehicle door opening/closing device, which can quickly determine a failure of an opening/closing switch without using a timer.
Means for solving the problems
In one aspect of the vehicle door opening/closing device of the present invention, the vehicle door opening/closing device includes:
an opening/closing member that opens and closes a door provided in a vehicle;
an external switch and an internal switch that receive an opening/closing operation of the opening/closing member by a user;
a drive unit that drives the opening/closing member to open/close based on the states of the external switch and the internal switch; and
and a failure detection unit that detects a failure of the external switch and/or the internal switch based on a relationship between a state of the external switch and a vehicle speed and/or a relationship between a state of the internal switch and an open/close state of the opening/closing member.
In one aspect of the method for detecting a failure in a door opening/closing device of a vehicle according to the present invention, the method includes the steps of:
receiving an opening and closing operation of the opening and closing member by a user via the outer switch and the inner switch; and
and detecting a failure of the external switch and/or the internal switch based on a relationship between a state of the external switch and a vehicle speed and/or a relationship between a state of the internal switch and an open/close state of the opening/closing member.

Detailed Description
Embodiments of the present invention will be described below with reference to the drawings.
The inventors of the present invention considered that, if (i) the relationship between the state of the outer/inner switch and the vehicle speed, or (ii) the relationship between the outer/inner switch and the open/close state of the door, it is possible to detect whether or not the outer/inner switch of the door opening/closing device of the vehicle is stuck (i.e., short-circuited) without using a timer.
Next, the above idea will be explained. Fig. 1 is a diagram showing a rear door 10, an outer switch 21, and an inner switch 22 of a vehicle. As shown in fig. 1A, the outer switch 21 is provided outside the back door 10. The external switch 21 is turned on when a user performs a pressing operation with a finger. As shown in fig. 1B, the inner switch 22 is provided at a lower portion of the back door 10. The inner switch 22 is turned on when a user presses it with a finger.
When the external switch 21 is turned on, the driving unit drives the back door 10 to the open state. Conversely, when the inner switch 22 is turned on, the drive unit drives the back door 10 to the closed state.
The above (i) is based on the following idea: since the external switch 21 located outside the vehicle cannot be operated by a person during the traveling of the vehicle, the external switch 21 is not turned on. Thus, in the present embodiment, if it is detected that the outer switch 21 is in the on state during traveling, it is determined that the outer switch 21 is stuck (i.e., short-circuited).
The above (ii) is based on the following idea: according to the arrangement of the inner switch 22, when the back door 10 is closed, the user cannot operate the inner switch 22 (specifically, the inner switch 22 is blocked), and therefore, the inner switch 22 does not become the on state. Thus, in the present embodiment, if it is detected that the inner switch 22 is in the on state when the back door 10 is closed, it is determined that the inner switch 22 is stuck (i.e., short-circuited).
Fig. 2 is a block diagram showing a configuration of a main part of the door opening and closing device of the present embodiment. When a driver of a vehicle or the like (hereinafter referred to as a "user") operates the outer switch 21 and the inner switch 22, the door opening/closing device 100 automatically opens and closes an opening/closing member 101 such as the back door 10 (fig. 1) using an electric motor as a drive source. In the present embodiment, the door opening/closing device 100 is mounted on a Vehicle such as a small truck or an SUV (Sport Utility Vehicle).
The door opening/closing device 100 includes an outer switch 21, an inner switch 22, an opening/closing member 101, a control unit 102, a drive unit 103, an alarm unit 104, a vehicle speed sensor 105, and an opening/closing sensor 106. The control unit 102 also functions as a failure detection unit, a drive control unit, and an alarm control unit.
As described with reference to fig. 1, the portion of the external switch 21 operated by the user is provided on the outer surface of the vehicle. The portion of the inner switch 22 operated by the user is provided at a position that is not visible to the user when the opening/closing member 101 (back door 10) is closed, in other words, at a position that is not operable by the user when the opening/closing member 101 is closed.
The opening/closing member 101 is a member that can open or close an opening provided in a vehicle, such as the back door 10 or a slide door.
Although not shown, the control Unit 102 includes, for example, a storage medium such as a CPU (Central Processing Unit), a ROM (Read Only Memory) in which a control program is stored, and a work Memory such as a RAM (Random Access Memory), and the control Unit 102 implements each function of failure detection, drive control, and alarm control by executing the control program by the CPU.
The driving unit 103 is implemented by an electric motor or the like, and drives the opening and closing member 101 (the back door 10 in the present embodiment) to open and close.
When detecting a failure of the outer switch 21 and the inner switch 22, the alarm unit 104 outputs a warning indicating that the door opening/closing device 100 cannot be used. The alarm unit 104 is realized by, for example, a meter display unit, and when a failure of the outer switch 21 or the inner switch 22 is detected, a system error indicating that the door opening/closing device 100 cannot be used is displayed on the meter display unit.
The opening/closing sensor 106 is a sensor that detects whether the opening/closing member 101 is in the open state or the closed state. In the case of the present embodiment, the opening/closing sensor 106 is provided in, for example, a lock mechanism on the vehicle body side where an engagement claw (not shown) of the back door 10 engages, and detects that the opening/closing member 101 (the back door 10) is in the closed state when the engagement claw of the back door 10 engages with the lock mechanism on the vehicle body side, and otherwise detects that the opening/closing member is in the open state.
Next, the operation of the door opening/closing device 100 according to the present embodiment will be described with reference to fig. 3 and 4. Fig. 3 is a flowchart showing the operation of the door opening/closing device 100 when the outer switch 21 is turned on, and fig. 4 is a flowchart showing the operation of the door opening/closing device 100 when the inner switch 22 is turned on.
As shown in fig. 3, when the external switch 21 is turned on in step S10, the controller 102 of the door opening/closing device 100 proceeds to step S11. In step S11, control unit 102 determines whether the vehicle speed is greater than 0km/h based on the input from vehicle speed sensor 105. When determining that the vehicle speed is greater than 0km/h, control unit 102 proceeds to step S12, determines that external switch 21 has failed (i.e., has stuck), stores the fact that the failure has occurred, and causes alarm unit 104 to display the failure in subsequent step S13. That is, when the vehicle speed is not 0km/h and the external switch 21 is in the on state, the control unit 102 determines that the external switch 21 has failed (that is, has stuck). On the other hand, if a negative result is obtained in step S11 (that is, if a result of the vehicle speed being 0km/h is obtained), control unit 102 proceeds to step S14. When the control unit 102 determines in step S14 that the failure of the external switch 21 is not stored, the process proceeds to step S15, and the drive unit 103 is controlled to open and drive the opening and closing member 101 (back door 10).
As shown in fig. 4, when the internal switch 22 is turned on in step S20, the controller 102 of the door opening/closing device 100 proceeds to step S21. In step S21, the control unit 102 determines whether the opening/closing member 101 (back door 10) is in the closed state based on the input from the opening/closing sensor 106. When determining that shutter 101 (back door 10) is in the closed state, control unit 102 proceeds to step S22, determines that inner switch 22 has failed (i.e., has stuck), stores the fact that the failure has occurred, and causes alarm unit 104 to display the failure in subsequent step S23. That is, when the opening/closing member 101 (back door 10) is in the closed state and the inner switch 22 is in the on state, the control unit 102 determines that the inner switch 22 has failed (that is, has become stuck). On the other hand, if a negative result is obtained in step S21 (that is, if a result that the opening/closing member 101 (back door 10) is in the open state is obtained), the control unit 102 proceeds to step S24. When the control unit 102 determines in step S24 that the internal switch 21 has not failed, the process proceeds to step S25, and the drive unit 103 is controlled to close and drive the opening and closing member 101 (back door 10).
As described above, according to the present embodiment, it is determined that the external switch 21 has failed based on the relationship between the state of the external switch 21 and the vehicle speed, specifically, when the vehicle speed is greater than 0km/h and the external switch 21 is in the on state. Further, according to the present embodiment, based on the relationship between the state of the inner switch 22 and the open/close state of the opening/closing member 101, specifically, when the opening/closing member 101 (back door 10) is in the closed state and the inner switch 22 is in the on state, it is determined that the inner switch 22 has failed.
With this configuration, it is possible to realize the vehicle door opening/closing device 100 that can quickly determine the failure of the external switch 21 and the internal switch 22 without using a timer.
The above-described embodiments are merely specific examples for carrying out the present invention, and the technical scope of the present invention should not be construed as being limited thereto. That is, the present invention can be implemented in various forms without departing from the spirit or main features thereof.
The failure detection function of the outer switch 21 and the failure detection function of the inner switch 22 described in the above embodiment may be both mounted on the vehicle, or only one of them may be mounted on the vehicle.
In the above-described embodiment, the case where the opening and closing member 101 is the back door 10, the outer switch 21 is provided on the outer surface of the back door 10, and the inner switch 22 is provided below the back door 10 has been mainly described, but the opening and closing member 101 is not limited to the back door 10, and may be, for example, a slide door. The outer switch 21 may be provided on the outer surface side of the vehicle, and the inner switch 22 may be provided at a position shielded when the opening/closing member 101 is in the closed state (i.e., a position that cannot be operated by the user).
For example, an outer/inner switch for opening and closing a door by a crew from the outside of the vehicle is provided on the outer surface side of the vehicle body of the bus. The above-described failure detection method for the external switch can be applied to the failure detection for the external switch of the external/internal switch. That is, it is considered that the crew member's operation to turn on the external switch is only to determine that the external switch has failed if the external switch is in the on state when the vehicle speed is 0km/h, except when the vehicle speed is 0 km/h.
Further, in the above-described embodiment, the case where it is determined that the external switch 21 has failed when the vehicle speed is greater than 0km/h and the external switch 21 is in the on state has been described, but it may be configured such that it is determined that the external switch 21 has failed when the vehicle speed is greater than a predetermined value and the external switch 21 is in the on state. For example, in the case of a work vehicle or the like, the following situation is also possible: the operation of the outer switch 21 during traveling is received, and the opening/closing member 101 is driven to open even during traveling after the operation is received. In consideration of this, the threshold value of the vehicle speed used for determining the failure of the external switch 21 may be set to a value other than 0 km/h. Specifically, in step S11 (fig. 4), it is determined whether the vehicle speed is greater than a predetermined value (for example, 60 km/h).
The present application is based on the japanese patent application (japanese patent application 2018-179886), filed on 26.9.2018, the contents of which are hereby incorporated by reference in their entirety.
