[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vehicle load control device that selectively executes a lock operation and an unlock operation of a door lock mechanism based on a command signal from a portable transmitter, and in particular, using the command signal.Lifting device for wheelchair provided in vehicleThe present invention relates to a vehicle load control apparatus capable of performing the above control operation.
[0002]
[Problems to be solved by the invention]
For example, in a handicapped car provided with a lifting device for a wheelchair corresponding to the back door or side door (passenger seat door), the door lock mechanism provided on the back door or side door is released, It is desirable that a series of operations of opening and lowering the lifting device can be performed with a simple operation. As a means for satisfying such a requirement, for example, it is conceivable to use a remote controller (portable transmitter) of a keyless entry system for a vehicle.
[0003]
Specifically, in the keyless entry system, when the output operation of the unlock signal (command signal for unlocking the door lock mechanism) continues for a preset threshold time or longer, during the operation period It is conceivable that a series of control operations such as opening the back door or side door and lowering the lifting device, and subsequent control operations such as raising and lowering the lifting device and closing the back door or side door are considered. Yes.
[0004]
However, in the keyless entry system, the operation enabling condition generally includes at least that the ignition key is not inserted into the key hole and the door is not opened. When a driver's seat door or the like is opened during execution of a series of control operations related to the lifting device, the control operation is inadvertently stopped halfway, resulting in a problem that the usability becomes extremely poor.
[0005]
The present invention has been made in view of the above circumstances, and its purpose is:Lifting device for wheelchair provided in vehicleIt is to provide a vehicle load control device that can smoothly perform a series of control operations for driving a vehicle using a portable transmitter for locking and unlocking operations of a door lock mechanism. .
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention satisfies at least a predetermined operable condition including an open / closed state of a vehicle door when a command signal from a portable transmitter is received for a predetermined signal recognition time or longer. In the vehicle load control device provided with a control means that validates the command signal on the assumption that the door lock mechanism is locked or unlocked.
The control means, when the reception state of the command signal continues for a threshold time set longer than the signal recognition time, only during the reception period, Control for driving a door opening / closing mechanism provided to open / close a specific vehicle door to open the specific vehicle door, wheelchair provided at a position corresponding to the specific vehicle door in the vehicle Control for driving the lifting device to lower the lifting device from the original position to the bottom dead center position, control for moving the lifting device from the bottom dead center position to the original position, driving the opening / closing mechanism to perform the specific operation Control to close the vehicle doorEven if the vehicle door is opened during the execution of the series of control operations, the command signal is kept valid and the control operation is continued without being interrupted. It is made into a structure (Claim 1).
[0007]
According to this configuration, when the operation of transmitting the command signal from the portable transmitter is performed for a preset signal recognition time or longer, the control means that has received the command signal includes at least a predetermined state including the open / closed state of the vehicle door. Assuming that the operable condition is satisfied, the command signal is validated to selectively execute the lock operation and the unlock operation of the door lock mechanism. In addition, if the operation of transmitting the command signal from the portable transmitter is continuously performed for the threshold time set longer than the signal recognition time, the control means only during the reception period of the command signal., Control for driving a door opening / closing mechanism provided to open / close a specific vehicle door to open the specific vehicle door, wheelchair provided at a position corresponding to the specific vehicle door in the vehicle Control for driving the lifting device to lower the lifting device from the original position to the bottom dead center position, control for moving the lifting device from the bottom dead center position to the original position, driving the opening / closing mechanism to perform the specific operation Control to close the vehicle doorEven if the vehicle door is opened during the execution of the series of control operations, the command signal is kept valid and the control operation is continued without being interrupted. It becomes like this.
[0008]
in this case,It relates to the drive of a lifting device for wheelchairsA series of control operations are performed during the execution of the series of control operations.(In fact, something other than a specific vehicle door)Even when the command signal is released, the command signal is kept valid and the control operation is continued without being interrupted. In other words, the command signal can be activated to enable the command signal. Since the vehicle door opening / closing state is excluded from the conditions, the aboveWheelchair lifting deviceEven when the vehicle door is opened and closed during execution of a series of control operations for driving, the control operation is not inadvertently stopped. Therefore,Wheelchair lifting deviceA series of control operations for driving the door can be smoothly performed using a portable transmitter for the lock operation and unlock operation of the door lock mechanism.Wheelchair lifting deviceUsability is improved.
[0009]
In order to achieve the above-mentioned object, when a command signal from the portable transmitter is received for a preset signal recognition time or more, a predetermined operable condition including at least an opening / closing state of the vehicle door is satisfied. In the vehicle load control device provided with a control means that validates the command signal on the premise that the door lock mechanism is locked or unlocked,
In the operable condition, the basic condition is that the vehicle door is not opened, and the control means is configured to receive the command signal in a state where the operable condition is satisfied. When the signal exceeds the threshold time set longer than the signal recognition time, only during the reception period, Control for driving a door opening / closing mechanism provided to open / close a specific vehicle door to open the specific vehicle door, wheelchair provided at a position corresponding to the specific vehicle door in the vehicle Control for driving the lifting device to lower the lifting device from the original position to the bottom dead center position, control for moving the lifting device from the bottom dead center position to the original position, driving the opening / closing mechanism to perform the specific operation Control to close the vehicle doorConfigured to run
When the command signal is received when the vehicle door is opened, the operating condition is satisfied when the reception state continues for a delay time set to a value longer than the signal recognition time by a predetermined time or more. It is good also as a structure which provides the invalidation means to invalidate the said basic conditions and to perform the locking operation | movement or the unlocking operation | movement of the said door lock mechanism by the said control means (Claim 2).
[0010]
According to this configuration, since the basic condition in the operable condition is not satisfied in the state where the vehicle door is opened, the operation for transmitting the command signal from the portable transmitter is set in advance as the signal recognition time. Even if the above is performed, the command signal is not validated, but when the transmission operation is operated until a delay time set to a value longer than the signal recognition time by a predetermined time or more elapses, the invalidating means However, the basic condition in the operable condition is invalidated. As a result, even when the vehicle door is open, when the operation of transmitting the command signal from the portable transmitter is continued for the delay time or longer, the command signal is validated and the door lock mechanism is locked. When the operation for transmitting the command signal continues for the threshold time or longer after the delay time has elapsed, the control meansWheelchair lifting deviceA series of control operations for is performed.
[0011]
in shortThe vehicle door is openIn other words, the command signal from the portable transmitter is essentially delayed even when the door lock mechanism cannot be locked or unlocked by the command signal from the portable transmitter. By performing an operation to send more than an hour,The locking or unlocking operation of the door lock mechanismIt will be possible and will be practically convenient.
[0012]
Further, when the door lock mechanism is unlocked when the vehicle door is closed, the control means automatically executes the lock operation of the door lock mechanism when a predetermined timer time elapses. The timer lock control may be executed (claim 3).
[0013]
According to this configuration, when the door lock mechanism is unlocked in the closed state of the vehicle door, the so-called timer lock operation of automatically locking the door lock mechanism when a predetermined timer time has elapsed. However, the timer lock operation is not performed when the door lock mechanism is unlocked while the vehicle door is open. For this reason, it is possible to prevent the situation where the door lock mechanism is left unlocked and improve security against theft, and the timer lock operation is not performed carelessly after the vehicle door is opened. Therefore, it is possible to prevent a situation where the key is closed in the passenger compartment.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
(First embodiment)
A first embodiment in which the present invention is applied to a handicapped car equipped with a lifting device for a wheelchair will be described below with reference to FIGS.
In FIG. 2, the electrical configuration of the entire system is schematically shown by a combination of functional blocks. In FIG. 1, a remote controller 1 (corresponding to a portable transmitter in the present invention) using a radio signal as a transmission medium is provided with a momentary type lock switch 2 and an unlock switch 3, and these switches 2 and 3 In each state in which is operated, a lock signal SLK and an unlock signal SUL (each corresponding to a command signal in the present invention) including a predetermined identification code are repeatedly transmitted through the antenna 1a.
[0015]
The receiving unit 4 is provided on the handicapped car side so as to be able to receive the radio signal from the remote controller 1, and in each case the lock signal SLK and the unlock signal SUL from the remote controller 1 are received via the antenna 5a. The receiving apparatus 5 outputs the reception signals SLK ′ and SUL ′, respectively, and a main controller 6 (corresponding to the control means in the present invention) that receives the output signal from the receiving apparatus 5. In this case, in addition to the output signal from the receiving device 5, the main controller 6 includes a key remind switch 7 that is turned on in a state where an ignition key is inserted into the key hole, and a door provided on each door of the handicapped car. A signal from the switch 8 group is received, and a control operation to be described later is performed based on those input signals and a program stored in advance.
[0016]
The door lock control unit 9 serving as a vehicle load is configured to lock and unlock door lock mechanisms (not shown) for a driver seat, a passenger seat door, a passenger seat door, and a back door provided in the handicapped car. The operation is for selectively performing the operation, and the lock and unlock operations are performed based on a command signal from the main controller 6.
[0017]
A back door actuator 10 as a vehicle load serves as a drive source of a door opening / closing mechanism (not shown) for opening and closing the back door, and is operated based on a command signal from the main controller 6. It has become so. The lifting device 11 as a vehicle load is for lifting the wheelchair and is provided at a position corresponding to the back door.AndThe lifting device 11 is also configured to be operated by a command signal from the main controller 6.
[0018]
In addition, it is good also as a structure which provides the raising / lowering apparatus 11 in the position corresponding to a side door (passenger seat door), and in this case, it replaces with the back door actuator 10, and the door opening / closing mechanism for opening and closing the applicable side door A side door actuator serving as a drive source (not shown) is provided.
[0019]
FIG. 1 shows a portion related to the gist of the present invention (control routine when receiving the unlock signal SUL from the remote controller 1) in the control contents by the main controller 6, and this is related to the following. It explains with an effect | action.
[0020]
In FIG. 1, the main controller 6 receives the input signal SUL ′ from the receiving device 5, that is, when receiving the unlock signal SUL from the remote controller 1 (“YES” in step A1), the input It is determined whether or not the state has continued for 0.5 seconds or longer, which is a preset signal recognition time (step A2). If the input state of the reception signal SUL ′ lasts for less than 0.5 seconds, it is determined as “NO” in step A1, and the process returns as it is. If it continues for 0.5 seconds or more, the ignition key is inserted into the keyhole. Is determined based on a signal from the key remind switch 7 (step A3).
[0021]
When the ignition key is inserted into the key hole (when the key remind switch 7 is turned on), the process returns as it is, but when the ignition key is not inserted into the key hole, the door lock control unit 9 An unlock command signal is output to (step A4). Thereby, in the door lock control unit 9, the unlocking operation of each door lock mechanism for the driver's seat door, the passenger seat door, the passenger seat door, and the back door is executed.
[0022]
After execution of the above step A4, it is determined whether or not the input state of the reception signal SUL ′ is continued (step A5). If “NO” is determined, doors (driver seat door, passenger seat door, Whether or not the passenger seat door and the back door) are opened is determined based on a signal from the door switch group 8 (step A6). If any door is open, the process returns as it is. If all doors are closed (“NO” in step A6), the process returns after executing step A7 for setting the timer lock. .
[0023]
Here, although not specifically illustrated, in the control unit 6, the door is opened during a period before a preset timer time (for example, about 30 seconds) continues after the timer lock is set as described above. When the door lock controller 9 is not opened, a lock command signal is output to the door lock controller 9, so that the door lock control unit 9 has a driver seat door, a passenger seat door, a passenger seat door, and a back door. Thus, a lock operation (so-called timer lock operation) of each door lock mechanism is performed.
[0024]
On the other hand, if “YES” is determined in Step A5, that is, if the input state of the reception signal SUL ′ is continued after execution of Step A4, the input state of the reception signal SUL ′ is It is determined whether or not the threshold time set longer than the signal recognition time (0.5 seconds) has continued, for example, 1.5 seconds or more (step A8).
[0025]
If the input continuation state of the received signal SUL ′ does not reach 1.5 seconds, it is determined as “NO” in step A5 and the process proceeds to step A6. The processing routine A9 is executed until the input of the reception signal SUL ′ is stopped (until “YES” is determined in step A10), and when the reception is stopped, the process returns.
[0026]
In the control operation processing routine A9, the control for operating the back door actuator 10 to open the back door, the control for operating the lifting device 11 in the downward direction from the completion of the opening, and the lifting device 11 being the bottom dead center. After reaching the position, control to reversely move the lifting device 11 in the upward direction, and control to close the back door by operating the back door actuator 10 after the lifting device 11 returns to the original position.
[0027]
In short, as a result of the above-described control being performed on the control unit 6 side, the unlock switch 3 of the remote controller 1 is set to 0 in a state where the operable condition that the ignition key is not inserted into the key hole is satisfied. When a single push operation of turning on for 5 seconds (signal recognition time) or more and less than 1.5 seconds (threshold time) is performed, the unlock signal SUL transmitted in response to the operation is used to An unlocking operation is performed (see (1) and (2) in FIG. 3 showing an operation timing chart of each part).
[0028]
At this time, when all the doors are closed during the unlocking operation as described above, by setting a timer lock, when a preset timer time (about 30 seconds) has elapsed thereafter The timer lock operation of automatically locking the door lock mechanism is executed (see (1) in FIG. 3), but if any door is opened, the execution of the timer lock operation is postponed. (Refer to (2) in FIG. 3).
[0029]
Further, when a continuous pressing operation of continuously turning on the unlock switch 3 of the remote controller 1 for 1.5 seconds or more is performed, the unlock switch 3 is operated after the unlocking operation of the door lock mechanism described above is executed. Only during the period, a series of control operations such as opening the back door, lowering and raising the elevating device 11, and closing the back door are performed (see (3) in FIG. 3).
[0030]
According to the above-described configuration of the present embodiment, since the open / close state of the vehicle door is excluded from the operable conditions for enabling the unlock signal from the remote controller 1, the back door opening / closing and the lifting device 11 Even when the door is opened during the execution of a series of control operations including lowering and rising, the control operation is continued without being interrupted. As a result, a series of control operations involving driving of the back door actuator 10 and the lifting device 11 can be smoothly performed using the remote control 1 for the lock operation and unlock operation of the door lock mechanism. , Its usability will be improved.
[0031]
Moreover, when the door lock mechanism is unlocked with the handicapped car door closed, the door lock mechanism is automatically activated when a preset timer time (for example, 30 seconds) elapses. Although the timer lock operation is performed to lock, the timer lock operation is not performed when the door lock mechanism is unlocked when the door is open. It is possible to prevent the mechanism from being left unlocked and improve security against theft, and the timer lock operation will not be inadvertently performed after the door is opened. There is an advantage that it is possible to prevent the occurrence of a situation where the key is closed in the room.
[0032]
(Second Embodiment)
4 to 6 show a second embodiment of the present invention. Hereinafter, only portions different from the first embodiment will be described.
That is, the hardware configuration of the second embodiment is substantially the same as that of the first embodiment as shown in FIG. 5, but instead of the receiving device 5, the invalidating means in the invention of claim 2 is used. The difference is that a functioning receiving device 12 is provided. The receiving device 12 is adapted to receive a signal from the door switch group 8, and when the unlock signal SUL is received through the antenna 12a in a state where any of the doors of the handicapped car is opened, the reception is performed. Until the delay time τ (for example, 1 to 1.5 seconds) set longer than the signal recognition time (0.5 seconds) elapses after the start, the unlock signal SUL is invalidated and the received signal SUL ′ The output is stopped and the output of the reception signal SUL ′ is started only when the delay time τ elapses.
[0033]
On the other hand, the contents of control by the main controller 6 are shown in FIG. In FIG. 4, when the reception signal SUL ′ is input from the reception device 5, that is, when the unlock signal SUL is received from the remote controller 1 (“YES” in step B1), the main controller 6 performs the key Whether or not the ignition key is inserted into the hole is determined based on a signal from the key remind switch 7 (step B2).
[0034]
If the ignition key is inserted into the key hole (when the key remind switch 7 is turned on), the process returns as it is, but if the ignition key is not inserted into the key hole, the door (driver's seat door) Whether the passenger seat door, the passenger seat door, and the back door) are opened is determined based on a signal from the door switch group 8 (step B3).
[0035]
If “NO” is determined in this step B3, that is, if all doors are closed(In other words, this corresponds to the case where the condition that the door is not opened (basic condition in the invention of claim 2) is satisfied)In step S4, it is determined whether the input state of the reception signal SUL 'has continued for 0.5 seconds or more. If the input state of the reception signal SUL ′ lasts for less than 0.5 seconds, it is determined as “NO” in step B1, and the process returns as it is. If it continues for 0.5 seconds or more, the door lock control unit 9 is unlocked. A lock command signal is output (step B5). Thereby, in the door lock control unit 9, the unlocking operation of each door lock mechanism for the driver's seat door, the passenger seat door, the passenger seat door, and the back door is executed.
[0036]
After the execution of step B5, it is determined whether or not the input state of the reception signal SUL ′ is continued (step B6). If “NO” is determined, the doors (driver seat door, passenger seat door, Whether or not the passenger seat door and the back door) are opened is determined based on the signal from the door switch group 8 (step B7). If any door is open, the process returns as it is. If all doors are closed (“NO” in step B7), the process returns after executing step B8 for setting the timer lock. .
[0037]
Here, in the control unit 6, as described in the first embodiment, a period before a preset timer time (for example, about 30 seconds) continues after the timer lock is set as described above. When the door is not opened, the lock command signal is output to the door lock controller 9, so that the door lock control unit 9 has a driver's seat door, a passenger seat door, a passenger seat door. And the lock operation (so-called timer lock operation) of each door lock mechanism for the back door is executed.
[0038]
On the other hand, if “YES” is determined in step B6, that is, if the input state of the reception signal SUL ′ is continued after execution of step B5, the input state of the reception signal SUL ′ is the threshold time. For example, it is determined whether or not it has continued for 1.5 seconds or longer (step B9).
[0039]
When the input continuation state of the received signal SUL ′ has not reached 1.5 seconds, “NO” is determined in Step B6 and the process proceeds to Step B7. The processing routine B10 is executed until the input of the reception signal SUL ′ is stopped (until “YES” is determined in step B11). When the reception is stopped, the process returns.
[0040]
In the control operation processing routine B10, the control for operating the back door actuator 10 to open the back door, the control for operating the lifting device 11 in the downward direction from the original position after the opening is completed, and the lifting device 11 being the bottom dead center. After reaching the position, control to reversely move the lifting device 11 in the upward direction, and control to close the back door by operating the back door actuator 10 after the lifting device 11 returns to the original position.
[0041]
If “YES” is determined in Step B3, that is, if any of the doors is opened, a predetermined delay time τ (for example, 1 to 1.5 after the input of the reception signal SUL ′ is started). It is determined whether or not (second) has elapsed (step B12). If "YES" is determined here, the process proceeds to the determination step B4. If "NO" is determined, it is determined whether or not the input state of the reception signal SUL 'is continued (step B13).
[0042]
If "NO" is determined in the step B13, the process returns as it is. If "YES" is determined, the process returns to the step B3. Therefore, when the input state of the reception signal SUL ′ is continued for the delay time τ or longer with one of the doors opened (“YES” in step B12), the input state continues for another 0.5 seconds. At that time (when it is determined “YES” in step B4), the control after the output step B5 of the unlock command signal is executed, but the input state of the reception signal SUL ′ continues for the delay time τ or more. If not, the unlock command signal output step B5 as described above is not executed.
[0043]
In short, as a result of performing the above-described control on the control unit 6 side, the unlock switch 3 of the remote control 1 is operated with all the doors closed and the ignition key is not inserted into the key hole. When a single press operation of turning on for 0.5 seconds (signal recognition time) or more and less than 1.5 seconds (threshold time) is performed, a door lock is generated by an unlock signal SUL transmitted in response to the operation. The mechanism is unlocked (see (1) in FIG. 5 showing an operation timing chart of each part). On the other hand, when any door is open, even if a single push operation of turning on the unlock switch 3 of the remote controller 1 for 0.5 seconds or more and less than 1.5 seconds is performed, the door lock The mechanism is not unlocked (see (2) in FIG. 5).
[0044]
At this time, when the unlocking operation is performed in the closed state of the door as described above, by setting the timer lock, when a preset timer time (about 30 seconds) has elapsed thereafter, A timer lock operation of automatically locking the door lock mechanism is executed (see (1) in FIG. 5).
[0045]
In addition, when the door is closed, as described above, when the unlocking switch 3 of the remote controller 1 is continuously turned on for 1.5 seconds or longer, the unlocking of the door lock mechanism described above is performed. After executing the locking operation, a series of control operations such as opening the back door, lowering and raising the lifting device 11 and closing the back door are performed only during the operation period of the unlock switch 3 (in FIG. 5). (See 3)).
[0046]
In addition, even when one of the doors is open, if the unlock switch 3 of the remote controller 1 is continuously turned on for a delay time τ (1 to 1.5 seconds) or longer, the on operation is performed. When the state continues for 0.5 second or more, the door lock mechanism is unlocked. When the state is continued for 1.5 seconds or more, the series of controls described above is performed only during the operation period of the unlock switch 3. The operation is performed (see (4) in FIG. 5).
[0047]
This embodiment configured as described above also achieves the same effect as the first embodiment. In particular, according to this embodiment, the receiving device 12 is connected to the remote controller 1 when the door is opened. The unlock signal SUL is invalidated until a delay time τ (for example, 1 to 1.5 seconds) set longer than the recognition time (0.5 seconds) of the unlock signal SUL has passed. It has become. As a result, when the operation of transmitting the unlock signal SUL from the remote controller 1 is continued for the delay time τ or more, the unlock signal SUL is enabled for the first time, and the unlocking operation of the door lock mechanism is performed. Further, after the delay time τ has elapsed, when the operation of transmitting the unlock signal SUL is continued for the threshold time (1.5 seconds) or longer, the main controller 6 controls the back door actuator 10 and the lifting device 11. A series of control operations for driving is executed.
[0048]
In other words, when the door is opened, the door lock mechanism can be obtained only by performing an operation of transmitting the unlock signal SUL from the remote controller 1 for a time shorter than the delay time τ (single pressing operation of the unlock switch 3). Can be unlockedUnlock signal S UL The door lock mechanism can be unlocked only when the transmission operation is performed for the delay time or longer.This is convenient for practical use.
[0049]
The present invention is not limited to the above-described embodiments, and can be expanded or modified as described below.
Although the back door actuator 10 and the lifting device 11 are given as examples of the vehicle load to be controlled, other electric devices may be used as the control target instead. Although the unlock signal SUL that continues for a threshold time (1.5 seconds) or more is used as a signal for instructing driving of the vehicle load, a system using the lock signal SLK is also possible.
[0050]
According to the present invention, as apparent from the above description, the vehicleLifting device for wheelchairs provided inDrivingPertaining toIt is possible to obtain a beneficial effect that a series of control operations can be smoothly performed using a portable transmitter for the lock operation and the unlock operation of the door lock mechanism.
