DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0007]
FIG. 1 is a perspective view of an automobile door 1 provided with an example of a door lock device 10 that can be controlled by the control device of the present invention, and FIG. 2 is a view in FIG. 1 when locked by the door lock device 10. II view and FIG. 3 are II arrow views in FIG. 1 when the latch is released by the door lock device 10.
[0008]
In the door lock device 10 of this example, a latch plate (not shown) that can be engaged with the striker 11 provided on the vehicle body side is pivotally attached to the base plate B by a shaft 12, and an open lever 13 is integrally formed on the shaft 12. And a locking / unlocking lever 14 connected to a locking / unlocking mechanism (not shown) is rotatably fitted. When the open lever 13 rotates in the direction of arrow A1 as shown in FIG. 2, the door 1 is latched in the closed state by the engagement of the latch plate and the striker 11, and the open lever 13 is shown in the direction of arrow A2 as shown in FIG. When the latch plate is rotated, the engagement between the latch plate and the striker 11 is released, and the latch of the door 1 is released. In this way, a latch mechanism that can perform a latch operation and a latch release operation according to the rotation direction of the open lever 13 is configured. The open lever 13 is always urged counterclockwise in FIG. 2 by a spring provided around the shaft 12. A plunger 15A of an actuator (electric motor) 15 is connected to one end portion 13A of the open lever 13, and the other end portion 13B is an engaging portion that can be engaged with the locking / unlocking lever 14. One end 13A and plunger 15A are arranged such that when plunger 15A moves in the direction of arrow B2 as shown in FIG. 3, open lever 13 rotates in the direction of arrow A2, and plunger 15A moves in the direction of arrow B1 as shown in FIG. When moving, the open lever 13 is connected so as to be allowed to rotate in the directions of arrows A1 and A2. On the other hand, the locking / unlocking lever 14 has a trifurcated shape in which three arm portions 14A, 14B, and 14C are formed. The left arm portion 14A in the drawing is connected to a locking / unlocking knob 16 (see FIG. 1) that can be operated up and down inside the door 1 and the right arm portion 14B in FIG. A pin 19 for receiving an elastic force from the spring 18 according to the rotational position of the locking / unlocking lever 14 is provided on the upper arm portion 14C in the figure so as to be able to be rotated. .
[0009]
In the door lock device 10 configured as described above, as shown in FIG. 2, the locking / unlocking knob 16 is pushed to the lower locking position PA-1 or the key mechanism 17 is turned to the locking position PB-1. The locking / unlocking lever 14 is held at the rotational position in the locking direction indicated by the arrow A1, and a locking / unlocking mechanism (not shown) connected to the locking / unlocking lever 14 locks the door 1. At this time, the inside knob switch S1 is turned ON by the arm portion 14C of the locking / unlocking lever 14. In such a locked state, when the actuator 15 is driven, the plunger 15A moves in the arrow B2 direction as shown in FIG. 3, and the open lever 13 engages the other end 13B with the locking lever 14. As it is, it rotates together with the locking lever 14 in the direction of arrow A2. As a result, the door 1 is unlocked by the locking / unlocking mechanism, and the latch is released by the latching mechanism. As described above, the unlocking operation by the locking mechanism and the unlatching operation by the latch mechanism are continuously executed by the actuator 15 (hereinafter, also referred to as “override operation”) to perform the override function. By such an override operation, as shown in FIG. 3, the locking / unlocking knob 16 is returned to the upper unlocking position PA-2, and the key mechanism 17 is returned to the unlocking position PB-2. On the other hand, in the locked state of FIG. 2, the door 1 is unlocked by pulling the locking / unlocking knob 16 to the upper unlocking position PA-2 or turning the key mechanism 17 to the unlocking position PB-2. Will be locked.
[0010]
In FIG. 1, reference numeral 2 denotes an inside handle as an inside operation means provided on the indoor side (inside the vehicle) of the automobile, and is provided on the inside of the door 1 so as to be pulled. S2 is an inside handle switch that is turned on when the inside handle 2 is pulled. Reference numeral 3 denotes an outside handle that is provided on the outside of the door 1 so as to be pulled.
[0011]
In the door lock device 10 of the present example, in order to perform an override function, a common actuator 15 is provided as a driving means for the locking / unlocking mechanism and the latch mechanism, and both the mechanisms are mechanically interlocked. . However, you may have a total of two electric motors that drive both of these mechanisms individually, and by controlling these motors in a related manner and driving both mechanisms as described above, the same override Can fulfill the function.
[0012]
FIG. 4 is a block diagram for explaining an example of the control device of the present invention. In the door lock device to be controlled by the control device of this example, the locking and unlocking mechanism and the latch mechanism in the door lock device 10 described above are individually driven and controlled by the first and second motors (electric motors) 20A and 20B. It has a configuration. For this purpose, the control device of this example includes a control means 30 for related control of the motors 20A and 20B. In addition, the locking / unlocking mechanism in this example is configured to be able to perform locking and unlocking operations according to the driving direction of the first motor 20A. The control means 30 is provided with first, second, and third timers 31, 32, 33 for measuring T1, T2, and T3 times, which will be described later. An I / S knob SW) S1 and an inside handle switch (I / S handle SW) S2 are connected.
[0013]
FIG. 5 is a flowchart for explaining the control operation by the control means 30.
[0014]
First, it is determined whether or not the inside handle switch (I / S handle SW) S2 is ON, that is, whether or not the first pull operation of the inside handle 2 has been performed (step S1), and when the switch S2 is turned ON Determines whether the inside knob switch (I / S knob SW) S1 is ON (step S2). When the switch S1 is OFF, that is, when the door 1 is in the unlocked state, the second motor 20B is driven and the latch is released by the latch mechanism (step S3).
[0015]
On the other hand, when the switch S1 is ON, that is, when the door 1 is locked, after waiting for the switch S2 to be turned OFF, that is, waiting for the pulling operation of the inside handle 2 to be released (step S4), the first Measurement of a predetermined operation impossible time T1 is started using the timer 31 (step S5). Thereafter, it is determined whether or not the switch S2 is turned on again within the inoperable time T1 (steps S6 and S7). When the measurement of the time T1 is completed without the switch S2 being turned on again, that is, the time T1. When the inside handle 2 is not pulled again, the first motor 20A is driven to unlock the locking / unlocking mechanism (step S8). Then, measurement of a predetermined operable time T2 is started using the second timer 32 (step S9). Thereafter, it is determined whether or not the switch S2 is turned on again during the time T2 (steps S10 and S11). When the switch S2 is turned ON again during the time T2, that is, when the second pulling operation of the inside handle 2 is performed within the time T2, the second motor 20B is driven and the latch is released by the latch mechanism. (Step S12). The override function is performed by such unlocking operation (step S8) and latch releasing operation (step S12) of the door 1.
[0016]
FIG. 6 is a timing chart when the override operation is performed in this way. That is, when the time T1 has elapsed since the first turn-on of the switch S2, the unlocking mechanism is unlocked (step S8), and when the switch S2 is turned on for the second time within the subsequent time T2, The latch mechanism releases the latch (step S12). When the door lock device 10 having the configuration shown in FIGS. 1 to 3 is to be controlled, the same actuator 15 is driven in step S12 by driving a common actuator 15 as a driving means for the locking / unlocking mechanism and the latch mechanism. Can fulfill the overriding function.
[0017]
Further, when the measurement of the time T2 is finished without the switch S2 being turned on again, that is, when the second pulling operation of the inside handle 2 is not performed within the time T2, the first motor 20A is driven and unlocked. The mechanism is locked (step S13). That is, as shown in FIG. 7, when the time T1 has passed since the first turn-on of the switch S2, the locking / unlocking mechanism is unlocked (step S8), and the switch S2 is turned on for the second time within the subsequent time T2. When there is not, the locking / unlocking mechanism performs locking operation (step S13).
[0018]
Further, when the switch S2 is turned on within the operation disabled time T1, the process proceeds from step S6 to step S14, and after performing a determination operation as described later in step S14, the process returns to step S4, and the switch S2 is turned off. , The measured value of the inoperable time T1 is cleared, and the inoperable time T1 is measured again (step S5). Accordingly, the second ON of the switch S2 within the inoperable time T1 is invalidated, and the inoperable time T1 is measured again each time it is invalidated, and the switch S2 is again waited for the second ON. become. In step S <b> 14, it is determined whether or not the number of re-measurements of the inoperable time T <b> 1 is equal to or greater than a predetermined set number n. When it is less than the set number n, the process returns to step S4. After that, when the switch S2 is not turned on within the newly measured non-operation time T1, the process proceeds from step S6, 7 to step S8. Then, the first motor 20A is driven to unlock the locking / unlocking mechanism. That is, as shown in FIG. 8, when the switch S2 is turned on within the time T1, the time T1 is measured again, and when the switch S2 is not turned on within the remeasured time T1, After the time T1 has elapsed, the door 1 is unlocked (step S8). From the time of the unlocking, the measurement of the time T2 is started as described above (step S9).
[0019]
In step S14, when it is determined that the number of re-measurements of the operation impossible time T1 is equal to or greater than the predetermined set number n, the operation ignore time T3 is measured after waiting for the switch S2 to be turned off (step S15, S16). When the switch S2 is turned on within the operation ignoring time T3, the process returns to step S15, and after waiting for the switch S2 to be turned off, the measured value of the operation ignoring time T3 is cleared, and again the operation ignoring time T3. Is measured again (step S16). Thereafter, when the switch S2 is not turned on within the newly ignored operation ignoring time T3, the control routine of FIG. 5 is terminated. That is, as shown in FIG. 9, when the number of re-measurements of the inoperable time T1 becomes equal to or greater than the predetermined set number n, the measurement of the time T3 is started, and each time the switch S2 is turned on within the time T3. The time T3 is measured again. Then, when the switch S2 is not turned ON within the re-measured time T3, the control routine of FIG. 5 ends after waiting for the elapse of the time T3. Therefore, when the number of re-measurements of the inoperable time T1 becomes equal to or greater than the predetermined set number n, the ON state of the switch S2 becomes invalid until this control routine ends.
[0020]
(Other embodiments)
The configuration of the door lock device to be controlled is not limited to the embodiment described above and is arbitrary, and the present invention can be widely applied to door lock devices that realize an override function by electrical control. .
[0021]
Further, based on the operation of the inside handle 2 and the inside side locking / unlocking knob 16 based on the operation of the inside side control system for controlling the locking / unlocking mechanism and the latch mechanism, and the operation of the outside handle 3 and the outside side key mechanism 17. An outside control system that controls the locking / unlocking mechanism and the latch mechanism may be provided. In this case, for example, when the control state of locking / unlocking by these two control systems is individually stored and the override operation is performed by the effective operation of the inside handle 2, the outside key mechanism 17 is In the locked state, the opening operation of the door 1 by the operation of the outside handle 3 can be made impossible. More specifically, in step S8 in FIG. 5, the unlocking operation is performed only by the inside control system, and the unlocking operation is not performed by the outside control system. The opening operation of the door 1 by the operation of the handle 3 can be made impossible. In particular, when the unlocking operation is performed in step S8 due to an inadvertent first operation of the inside handle 2, it is impossible to open the door 1 by operating the outside handle 3. This is effective in preventing theft.
[0022]
Further, the inside operation means provided on the inside of the vehicle is not limited to the inside handle 2 alone, and may be an inside switch such as a push button type that can be operated on the inside of the vehicle. In that case, the inside handle switch S2 can be used as the inside switch.
[0023]
【The invention's effect】
As described above, the automobile door lock control device of the present invention controls the electric motor so that the override operation is performed on the condition that the inside operation means provided in the interior of the automobile is operated twice. When executing the override operation, a double action for operating the inside operation means twice is required, and a useless override operation due to careless operation of the inside operation means can be eliminated.
[0024]
In addition, the double action of the inside operation means within a short time is invalidated by performing the override operation on condition that the second operation has been performed after the predetermined operation disabled time has elapsed since the first operation of the inside operation means. As a result, the execution condition of the override operation can be set more optimally. As a result, for example, when a push button type inside switch is used as the inside operation means, it is possible to avoid a situation in which the inadvertent continuous operation of the switch is invalidated and the override operation is performed wastefully.
[0025]
In addition, after the first operation of the inside operation means, the override operation is performed on the condition that the second operation is performed within a time obtained by adding the predetermined operable time to the inoperable time. When the inside operation means is operated twice without being noticed for a long time, it is possible to avoid a situation where the override operation is wasted.
[0026]
In addition, the second operation within the inoperable time from the first operation of the inside operation means is invalidated, and the inoperable time is measured again every time there is the second invalid operation, and the second operation is waited again. As a result, the execution condition of the override operation can be set more optimally. Furthermore, in that case, when the number of re-measurements of the inoperable time continues for a predetermined set number of times or more, it is overridden by waiting for the first operation of the inside operation means after waiting for the elapse of the predetermined operation ignoring time. The execution condition of the operation can be set even more optimally.
[0027]
Also, the unlocking operation by the locking / unlocking mechanism is performed after the first effective operation of the inside operation means, and the latch release operation by the latch mechanism is performed after the second effective operation of the inside operation means. The override operation can be performed in two steps.
[0028]
Moreover, it becomes effective in preventing theft by maintaining the state in which the door opening operation of the outside handle provided outside the door is not possible during the override operation.
[0029]
Further, two electric motors can be provided separately for driving the locking / unlocking mechanism and driving the latch mechanism, or one electric motor can be provided for both driving the locking / unlocking mechanism and driving the latch mechanism.
