Abstract

<P>PROBLEM TO BE SOLVED: To reduce the number of transmitters to be held and the number of buttons of the receiver in a system for remote control of a door of a vehicle. <P>SOLUTION: The transmitter, which has a lock button and an unlock button, repeatedly transmits a request signal when either the lock button or the unlock button is pressed. The request signal includes an ID code, a button code and a time code. The button code indicates discrimination between the lock/unlock buttons, and the time code indicates whether the button is continuously pressed longer than a prescribed time or pressed prescribed number of times. A receiver performs the lock/unlock control and opening/closing control of the door in accordance with the button code and the time code. A number-of-times code, which indicates the number of times of the operation of the button, can also be used instead of the time code. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a system for remotely controlling a vehicle door such as lock / unlock control or opening / closing control, and a receiver used for the door control system.

  Devices have already been proposed in which opening and closing of a vehicle door can be controlled remotely from the outside of the vehicle (see, for example, Patent Document 1 and Patent Document 2). All of the devices proposed in these patent documents are provided with a door-open switch and a door-close switch in a portable transmitter, and control the opening and closing of the door when or during the operation of these switches. is there.

  As a remote control of the vehicle, there is also a keyless entry device that performs door lock / unlock control. For this reason, for a vehicle having both remote door opening / closing control and door lock / unlock control, the user has to hold separate transmitters, which is inconvenient.

  In order to solve this problem, there has been proposed one that improves convenience by providing both functions of remote door opening / closing control and door lock / unlock control in one transmitter (Patent Document). 3, see Patent Document 4).

JP-A-6-55936 Japanese Patent Laid-Open No. 9-132983 JP-A-10-184128 Japanese Patent Laid-Open No. 10-211819

  However, the devices described in Patent Documents 3 and 4 are provided with four switches, that is, a lock switch, an unlock switch, a door open switch, and a door close switch, in one transmitter. For this reason, the number of parts increases, the transmitter becomes larger, and the cost increases.

  Therefore, the present invention provides a remote-operated door control system capable of reducing the number of transmitters to be held and reducing the size of the transmitter, and a receiver used in the system. It is the purpose.

  The present invention has been made to achieve the above object. A door control system according to the present invention includes a transmitter having a button for operating a door lock request and a button for operating a door unlock request, door open / close detecting means for detecting an open / closed state of a vehicle door, and a vehicle Door opening / closing drive means for opening / closing the door, lock / unlock control means for controlling locking / unlocking of the vehicle door, and a receiver.

  When operating the transmitter, the user operates the lock button and the unlock button in the first or second mode. Thereby, the lock / unlock request signals of the first and second modes are transmitted from the transmitter.

When the receiver receives the request signal of the first aspect from the transmitter, the receiver causes the lock / unlock control means to lock / unlock the door, and when receiving the request signal of the second aspect, Depending on the door open / closed state detected by the door open / close detection means, the door open / close drive means is caused to perform an opening or closing operation of the door.
Note that the request signals of the first and second modes are distinguished by, for example, the duration of operating the lock / unlock button or the number of operations.

  According to the present invention, door lock / unlock control and door opening / closing control can be performed by changing the button operation method of the transmitter, and the transmitter can be configured with a small number of buttons.

According to the present invention, in the remote-operated door control system, the number of transmitters to be held by the user can be reduced, and the transmitter can be downsized by reducing the number of buttons on the transmitter. it can.
Furthermore, according to the present invention, various door controls are possible depending on the operation mode of the transmitter.

Embodiments of the present invention will be described for each embodiment with reference to the drawings.
(Embodiment 1)
FIG. 1 shows a first configuration of a door control system, which performs a door lock / unlock control and door opening / closing control of a vehicle according to a transmitter 1 that transmits a request signal and the received request signal. A receiver 2 is provided.

The transmitter 1 is configured to be portable and can be carried outside the vehicle 3. The transmitter 1 includes a lock button 4 and an unlock button 5, and a microcomputer, a memory, and a transmission circuit (not shown).
In this example, when the operator wants to lock or unlock the door, the operator presses either the lock button 4 or the unlock button 5 for a short time (less than 2 seconds). When opening or closing the door, either the lock button 4 or the unlock button 5 is pressed for 2 seconds or more. The transmitter 1 outputs a request signal corresponding to how the buttons 4 and 5 are pressed.

FIG. 2 shows the structure of the request signal transmitted by the transmitter 1, and FIG. 3 shows processing executed by the microcomputer of the transmitter 1.
The request signal includes an 48-bit ID code, a 2-bit button code, and a 1-bit time code.
The ID code is a unique code assigned to identify the transmitter.

In the button code, the second bit represents on / off of the lock button 4, 1 represents on, and 0 represents off. The least significant bit represents on / off of the unlock button 5, 1 represents on, and 0 represents off.
The time code represents the time when the buttons 4 and 5 were pressed, 1 represents that the button was pressed for 2 seconds or more, and 0 represents less than 2 seconds. In this example, the button code and the time code represent the operation modes of the buttons 4 and 5.

A process of creating and transmitting a request signal in the microcomputer of the transmitter 1 will be described with reference to FIG. The illustrated process is repeatedly executed by interruption at predetermined time intervals.
In step T1 and step T3, it is determined whether or not the lock button 4 or the unlock button 5 has been pressed. If no button is pressed, the process of FIG. 3 is not executed.

If it is determined in step T1 that the lock button has been pressed, “10” is set in the button code in step T2. If it is determined in step T3 that the unlock button 5 has been pressed, "01" is set in the button code in step T4.
After the button code is set, the ID code stored in the memory is read (T5), and the time during which the button is continuously turned on is measured (T6). The measurement time is determined (T7), and if it does not continue for 2 seconds or more, the time code remains “0” (T9). If it continues for 2 seconds or more, “1” is set in the time code (T8).

The request signal shown in FIG. 2 is created by the above processing and transmitted to the outside (T10).
If the button is kept pressed, the process of FIG. 3 is repeated and the request signal is continuously transmitted.
If the button is pressed for 2 seconds or longer (Y in T7), the time code changes from 0 to 1 (T8).

  Returning to FIG. 1, the receiver 2 includes an antenna, a tuner, a CPU, a memory, and the like, and is disposed in the vehicle 3. When receiving the request signal, the receiver 2 outputs a signal for performing door lock / unlock control and door opening / closing control according to the content of the request signal and the content of the input signals from the various detection switches.

As the input signal, there are a courtesy switch for a driver's seat door, a courtesy switch for a passenger seat door, a courtesy switch for a sliding door, and a courtesy switch for a back door.
The output signal includes a signal to a lock motor that locks / unlocks each of the four doors, a signal to a door motor that opens and closes a sliding door, a buzzer that issues an alarm, and a signal to a hazard.

FIG. 4 shows the positional relationship between the door and the door motor in the vehicle 3.
In the illustrated example, a driver seat door 6 and a passenger seat door 7 are provided in front of the vehicle 3, a slide door 8 is provided on the rear left side, and a back door 9 is provided on the back surface. The sliding door 8 is driven to open and close by a door motor 10.

The operation of the receiver 2 will be described with reference to FIGS. FIG. 5 shows the overall flow, and FIGS. 6 to 8 show details of each part in the flow of FIG.
The relationship between each figure is as follows.
FIG. 5 Step S1 (flag operation): FIG.
FIG. 5 Step S2 (lock / unlock control): FIG.
FIG. 5 Step S3 (Door Open / Close Control): FIG.

The illustrated process is repeatedly executed at predetermined time intervals.
In step S1, the door lock / unlock request flag and the door opening / closing request flag are operated based on the button code and the time code of the request signal.
In step S2, door lock / unlock control is performed based on the door lock / unlock request flag and signals from various detection switches.
In step S3, door opening / closing control is performed based on the door opening / closing request flag and signals from various detection switches.

The request flag operation in step S1 will be described with reference to FIG.
It is determined whether the received request signal is a lock request signal (A1) or an unlock signal (A11). This determination is performed according to the button code of the request signal in FIG.
If it is a lock request signal (Y in A1), if the signal is received for the first time (Y in A2), the lock request flag is set to 1 (A3). In the case of an unlock request signal, if the signal is received for the first time (Y in A12), 1 is set in the unlock request flag (A13).

  Thereafter, if the door lock / unlock request signal is continuously received, the reception is not the first time, and the process proceeds from steps A2 and A12 to A4 and A14. Here, it is determined whether or not the request signal has continued for 2 seconds (whether the time code is 0 or 1). Until 2 seconds continue (N of A4 and A14), the request flag is not changed, and the process proceeds to step S2. If the operation of the buttons 4 and 5 is continued for 2 seconds, the time code of the request signal becomes “1”, so that 1 is set in the door close request flag or the door open request flag (A5, A15).

When the received signal is neither a door lock / unlock request signal (N of A1, A11), the door close request flag and the door open request flag are reset to “0” (A21, A22).
When the request flag operation ends, the process proceeds to the door lock / unlock control of FIG.
It is determined whether the lock request flag is “1” (B1) and whether the unlock request flag is “1” (B11). If any request flag is “0”, door lock / unlock control is not performed.

If the lock request flag is “1” (Y in B1), it is determined whether or not all the doors 6 to 9 are closed (B2). If Y here, the door is locked (B4), the lock request flag is reset to “0” (B5), the door close request flag is reset to “0” (B6), and then the answer back is performed. (B7).
Note that the answerback alerts the user or the like by making the buzzer ring differently from the ringing during normal door opening / closing drive (described later).
If N in step B2, the lock request flag is reset to “0” (B3).

If the unlock request flag is “1” in step B11, the door is unlocked (B12), the unlock request flag is reset (B13), and the answerback is performed (B14).
When the door lock / unlock control ends, the process proceeds to the door opening / closing control process of FIG.

It is determined whether the door close request flag is “1” (C1) and whether the door open request flag is “1” (C11). If any of the request flags is “0”, door opening / closing control is not performed.
If the door close request flag is “1” (Y in C1), it is determined whether or not the slide door is closed (C2). If it is N here, the sliding door is driven to close (C3), and the buzzer is intermittently driven during the closing drive (C4). When this process is repeated and the sliding door is fully closed (Y in C2), the door close request flag is reset (C5), and the lock request flag is set (C6).

Thereby, all the doors are locked at B4 via steps B1 and B2. Further, since the door closing drive in step C3 is not performed, there is no further door closing driving.
Note that the lock request flag set (C6) may be selectable by pressing the button or selecting a mode in the system.

  If the door opening request flag is 1 (Y of C11), it is determined whether or not the sliding door is fully opened (C12). This determination may be performed by a switch (not shown) that detects the fully open state of the slide door, but may be performed by other means. If N here, the sliding door is driven to open (C13), and the buzzer is intermittently driven during the closing drive (C14). When this process is repeated and the sliding door is fully opened (Y in C12), the door opening request flag is reset (C15). Further, since the door opening drive in step SC13 is not performed, there is no further door opening drive.

  When the user releases the button of the transmitter while the sliding door is being driven, the received signal is interrupted. Then, it becomes N in steps A1 and A11, and the door close request flag and the open request flag are reset (A21, A22), so steps C1 and C11 become N, and the drive of the slide door is stopped.

The operations according to the above processing are collectively described as follows.
(1) When the lock button 4 or the unlock button 5 is momentarily pressed (less than 2 seconds) by the transmitter 1, only the door is locked or unlocked. When the lock button 4 is pressed, the doors are not locked unless all the doors 6 to 9 are closed, but may be locked regardless of whether the doors are opened or closed.

  (2) When the buttons 4 and 5 are kept pressed, the door is locked or unlocked first, and when 2 seconds have elapsed, the sliding door 8 is closed or opened according to the open / closed state of the sliding door. Is called. However, if the lock button 4 is continuously pressed, the user's intention to close the open slide door is displayed, so the slide door is in the open state, so the first door lock is not performed and the door Locked when closed.

Alternatively, it is possible to select whether to lock or not when the sliding door is closed. In this case, there are a case where different ID codes are used depending on a combination of time for pressing a button and switch operation, and a case where a function that can be switched by a receiver is provided.
(3) When the buttons 4 and 5 are released while the sliding door 8 is being opened and closed, the opening and closing operation is stopped at that time.

(Modification 1-1)
A first modification of the first embodiment will be described with reference to FIG.
According to this example, when the lock button 4 is operated when the slide door 8 is open, the closing drive of the slide door 8 is immediately started. As a result, the sliding door is closed and the door is locked without waiting for the elapse of 2 seconds as in the first embodiment. That is, not the operation mode of the lock button 4, but the lock control or the slide door closing drive control is selected according to the open / closed state of the slide door when the lock signal is received.

The overall flow when this example is adopted is as follows.
FIG. 5 Step S1 (Flag Operation): FIG.
FIG. 5 Step S2 (lock / unlock control): FIG.
FIG. 5 Step S3 (Door Open / Close Control): FIG.

Hereinafter, FIG. 9 will be described, but the flow of FIG. 9 shows a modification of the flow of FIG. The same steps as those in FIG. 6 are denoted by the same reference numerals, and redundant description is omitted.
If it is determined that the request signal is a door lock request (Y in Step A1), it is determined whether or not all the doors 6 to 9 are closed (D1).

Here, if there is at least one door that is not closed, it is determined whether or not the slide door 8 is closed (D2). If the sliding door is open, “1” is set to the door closing request flag (A5). Accordingly, the door closing drive is immediately performed in the process of FIG. 8 without waiting for the passage of 2 seconds.
If all the doors are closed as a result of the closing drive of the slide doors (Y in D1), the lock request flag is set and lock control is performed.

When the request signal is a door unlock request (A11), the door open request flag is set when the request signal continues for 2 seconds or more, as in the process of FIG.
In this example, Steps A21 and 22 can be omitted. In this case, once the door opening / closing flag is set to “1”, the opening / closing drive continues until the button 4 or 5 is released until it is fully closed or fully opened.

(Modification 1-2)
A second modification of the first embodiment will be described with reference to FIG.
According to this example, when the slide door 8 reaches a predetermined position during the opening / closing drive of the slide door 8, the slide door 8 stops once, and the opening / closing drive is resumed after a predetermined time has elapsed.
The overall flow when this example is adopted is as follows.

FIG. 5 Step S1 (Flag Operation): FIG. 6 or FIG.
FIG. 5 Step S2 (lock / unlock control): FIG.
FIG. 5 Step S3 (Door Open / Close Control): FIG.
10 will be described below. Since the flow of FIG. 10 shows a modification of the flow of FIG. 8, the same steps as those of FIG.

  If the door close request flag is 1 (Y in C1) and the slide door is open (N in C2), it is determined whether or not the slide door is in a predetermined position (E1). The predetermined position is appropriately set between fully closed and fully opened (for example, an intermediate position). The predetermined position may be detected by a mechanical detection switch or by measuring an elapsed time from the start of the closing drive. If N here, the sliding door is driven to close (C3).

  When the sliding door is driven to close and reaches a predetermined position (Y of E1), the timer starts counting (E2, E3), and proceeds to step C4. Therefore, although the buzzer is driven, the door is not driven in step C3, so the slide door stops.

  Until the timer counts 0.5 seconds (N in E2), the sliding door remains stopped at the predetermined position. When 0.5 seconds have elapsed (Y in E2), after answering back (E5), the process proceeds to step C3 to resume the sliding door closing drive. Therefore, when the slide door reaches a predetermined position during the closing drive, the sliding door stops for 0.5 seconds and is then driven again.

  When the door opening request flag is 1 (Y of C11), the same as above, it is determined whether or not the sliding door is in a predetermined position (E11), and when the predetermined position value is reached (Y of E11), Timer timing starts (E12, E13). When 0.5 seconds elapse (Y of E12), the sliding door opening drive is resumed (C13).

(Embodiment 2)
The second operation of the receiver 2 will be described with reference to FIGS.
In the first embodiment, if the hand is released from the buttons 4 and 5 of the transmitter 1 while the sliding door is being opened and closed, the opening and closing drive is stopped. In contrast, in this example, the opening / closing drive is not stopped even when the buttons 4 and 5 are released, and the opening / closing drive is forcibly stopped when the buttons 4 and 5 are pressed again.

The system configuration of this example is the same as that in FIGS. 1 to 4 of the first embodiment.
FIG. 11 shows an overall flow of processing of the receiver 2, and FIGS. 12 to 14 show details of each part in the flow of FIG.
The relationship between each figure is as follows.
FIG. 11 Step S11 (Flag Operation): FIG.
FIG. 11 Step S12 (Forced stop flag operation): FIG.
FIG. 11 step S13 (lock / unlock control): FIG.
FIG. 11 step S14 (door opening / closing control): FIG.
FIG. 11 step S15 (forced stop control): FIG.

The process of FIG. 11 is repeatedly executed by interruption at predetermined time intervals.
In step S11, the lock / unlock request flag and the door opening / closing request flag are operated.
In step S12, a forced stop flag for door opening / closing drive is operated.
In step S13, door lock / unlock control is performed.
In step S14, door opening / closing control is performed. In step S15, control for forcibly stopping the door opening and closing drive is performed.

The request flag operation in step S11 will be described with reference to FIG. 12. Since the flow in FIG. 12 shows a modification of the flow in FIG. 6, the same steps as in FIG. Description is omitted.
In the process of FIG. 12, as with the process of FIG. 6, when the buttons 4 and 5 are pressed, the lock request flag or the unlock request flag is set. If the button is kept pressed for 2 seconds or longer, the door close request flag or the door open request flag is set.

  In FIG. 12, steps A21 and A22 in FIG. 6 are omitted. Therefore, in this example, the door opening / closing request flag is not reset even if the buttons 4 and 5 of the transmitter 1 are released while the sliding door is being opened and closed. Thus, the driving operation of the sliding door is not stopped until it is fully opened or fully closed by a door opening / closing process described later.

The forced stop flag operation in step S12 will be described with reference to FIG.
In step F1, it is determined whether or not the lock / unlock request signal is received for the first time. When the request signal is temporarily stopped and received again, the receiver 2 determines that the request signal is received for the first time. In step F2, it is determined whether or not the door opening or closing request flag is 1. If both are Y, 1 is set to the forced stop flag. If either is N, the forced stop flag is not set.

Therefore, if the buttons 4 and 5 are pressed again during the door opening / closing drive (the door opening / closing request flag is set), the forced stop flag is set by the processing of FIG.
Since the contents of the lock / unlock control in step S13 are as shown in FIG. 7, the description thereof is omitted here. That is, if the lock request flag is 1 and all the doors are closed, all the doors are locked. If the unlock request flag is 1, the door is unlocked.

  Since the content of the door opening / closing control in step S14 is as shown in FIG. 8 described above, description thereof is omitted here. That is, if the door close request flag is 1 and the sliding door is not closed, the door is closed. If the door opening request flag is 1 and the sliding door is not fully opened, the door is opened. In this example, as described above, the door closing / opening request flag is not reset even if the button is released while the sliding door is being opened / closed, so that the opening / closing drive continues.

The forced stop control in step S15 is as shown in FIG.
In step G1, it is determined whether the forced stop flag is 1. If N here, the forced stop is not performed. If Y here, it is determined whether or not the door close request flag is 1 (G2). If it is Y, it is opened in the reverse direction for 1 second (G3), and the door close request flag is reset (G4).
If it is N in step G2, it is closed in the reverse direction for 1 second (G5), and the door opening request flag is reset (G6).

  With the above processing, when the buttons 4 and 5 of the transmitter 1 are pressed during the sliding door opening and closing drive, the opening and closing drive is stopped. At this time, the sliding door being driven is driven in the reverse direction for 1 second and then stopped. In the case of the forced stop of the sliding door, there is a high possibility that something is caught in the door, but safety can be improved by driving in the reverse direction in this way. Driving in the reverse direction can be omitted.

(Modification 2-1)
A first modification of the second embodiment will be described.
In this example, the sliding door is temporarily stopped during the door opening / closing drive of the second embodiment, and the opening / closing drive in the same direction is resumed after 0.5 seconds. In the opening / closing drive control, the door opening / closing control in step S14 is performed by the process shown in FIG. The overall flow when this example is adopted is as follows.

FIG. 11 Step S11 (Flag Operation): FIG.
FIG. 11 Step S12 (Forced stop flag operation): FIG.
FIG. 11 step S13 (lock / unlock control): FIG.
FIG. 11 step S14 (door opening / closing control): FIG.
FIG. 11 step S15 (forced stop control): FIG.

(Modification 2-2)
A second modification of the second embodiment will be described with reference to FIGS. 15 and 16.
In this example, the sliding door is temporarily stopped during the door opening / closing drive. Thereafter, when the buttons 4 and 5 of the transmitter 1 are operated again, the opening / closing drive is resumed.
The relationship between FIGS. 15 and 16 and other flows is as follows.
FIG. 11 Step S11 (Flag Operation): FIG.
FIG. 11 Step S12 (Forced stop flag operation): FIG.
FIG. 11 step S13 (lock / unlock control): FIG.
FIG. 11 step S14 (door opening / closing control): FIG.
FIG. 11 step S15 (forced stop control): FIG.

The operation of the forced stop flag in step S11 will be described with reference to FIG. 15, but the flow in FIG. 15 shows a modification of FIG. The description to be omitted is omitted.
Before the forced stop flag operation F1 to F3, it is determined in step H1 whether or not either the door close interrupt flag or the door open interrupt flag is set. The initial setting value of each flag is 0.

As will be described later, the door closing or door opening interruption flag is set to “1” when a predetermined position is reached during opening / closing driving of the sliding door. According to the process of FIG. 15, if the door close or door open interruption flag is set, the forced stop flag is not set.
FIG. 16 shows the door opening / closing control process, which is a modification of FIG. 10 described above. Therefore, in FIG. 16, the same steps as those in FIG.

  When the sliding door is closed or opened and reaches a predetermined position (Y of E1, E11), a door closing or opening interruption flag is set (J5, J15). Further, since the process does not proceed to steps C3 and C13, the door closing or opening drive is interrupted. When the door close or open flag is set, N is set in step H1, so that the forced stop flag in FIG. 15 is not set even if the lock / unlock button is operated again.

When the user operates the button of the transmitter 1 in this interrupted state, a lock / unlock signal is received (Y of C1, C11), so the process proceeds from steps J1, J11 to J2, J12. If the received signal is a lock signal at step J1 and an unlock signal at J12, the door closing or opening interruption flag is reset (J3, J23). And it is answered back for warning (J4, J24), and the opening / closing drive (C3, C13) is resumed.
After the door closing or opening interruption flag is reset, the forced stop flag can be set thereafter.

(Embodiment 3)
A third operation of the receiver 2 will be described with reference to FIG.
In this example, when the road on which the vehicle 3 is parked is large and the door motor 10 is overloaded when the slide door 8 is opened and closed, the slide door is not driven to open and close.
The flow of FIG. 17 is added to the subsequent stage of the flag operation flow of FIG. 6, FIG. 9 or FIG. The overall flow when the present example is applied to the first and second embodiments is as follows.

(Applied to Embodiment 1)
FIG. 5 Step S1 (flag operation): (FIG. 6 or FIG. 9) + FIG.
FIG. 5 Step S2 (lock / unlock control): FIG.
FIG. 5 Step S3 (door opening / closing control): FIG. 8 or FIG.

(Applied to Embodiment 2)
FIG. 11 Step S11 (Flag Operation): FIG. 12 + FIG.
FIG. 11 Step S12 (Forced stop flag operation): FIG.
FIG. 11 step S13 (lock / unlock control): FIG.
FIG. 11 step S14 (door opening / closing control): FIG.
FIG. 11 step S15 (forced stop control): FIG.
S12 to S15 can also be performed as in Modification 2-1 or Modification 2-2.

The operation of FIG. 17 will be described.
After the flag operation of FIG. 6, FIG. 9, or FIG. 12, it is determined whether the door close or open request flag is set (K1, K11).
If the door close or open request flag is set (Y of K1, K11), it is determined whether or not the uphill or downhill road detected by the inclination sensor (not shown) exceeds a predetermined value (K2). K12). If the road gradient exceeds a predetermined value, the door closing or request flag is reset (K3, K13) and the answer back is performed (K4, K14).

  As a result, the sliding door is not opened and closed in step S14. On the other hand, if the road gradient is equal to or smaller than the predetermined value (N of K2, K12), the door opening / closing request flag is not reset. If the predetermined condition is satisfied, the sliding door is opened / closed in step S14. .

  The means for detecting the road gradient is not limited to the inclination sensor, and other detection methods such as using a load current value flowing through the motor can be used. When the load current value of the motor is used, a value larger than the current value when the sliding door is driven on a flat road is set as the determination value (the current value increases as the motor load increases).

(Embodiment 4)
The fourth operation of the door control system will be described with reference to FIGS. This example relates to door control when the vehicle 3 has two slide doors, and the two slide doors are opened or closed separately or together by operating the transmitter 1.
FIG. 18 shows a vehicle to which this example is applied. Except for the point that the slide doors 8 and 12 are on both the left and right sides, it is the same as FIG.
In this example, since the sliding doors 8 and 12 are distinguished and operated, a shift button is added to the transmitter, and which of the two sliding doors is opened / closed is determined by the number of times the button is pressed.

FIG. 19 shows a system configuration. Since this configuration is substantially the same as that of FIG. 1 of the first embodiment, a duplicate description is omitted. In addition to the lock button 4 and the unlock button 5, the transmitter 1 is provided with a shift button 11.
The receiver 2 receives slide door courtesy switches SW3 and SW4 from each of the two slide doors.

FIG. 20 shows the structure of a request signal transmitted from the transmitter 1.
The ID code, button code, and time code are the same as those shown in FIG. In this example, a 2-bit number code is added. This number code represents the number of times the shift button 11 is pressed before the buttons 4 and 5 are pressed. When the shift button 11 is not pressed, “00” is displayed. When the shift button 11 is pressed once, “01” is displayed. When the shift button 11 is pressed twice, “10” is displayed. In this example, the button code, the time code, and the frequency code represent the operation mode of the button of the transmitter.

The request signal transmission process in the microcomputer of the transmitter 1 will be described with reference to FIGS. The illustrated process is repeatedly executed by interruption at predetermined time intervals.
Since steps T1 to T10 in FIG. 21 are substantially the same as those in FIG. 3 in the first embodiment, the same reference numerals are given in FIG.
In this example, when it is not determined that the lock / unlock button has been operated (N of T1 and T3), it is determined whether or not the shift button has been operated (T21).

  If the shift button has been pressed, the process proceeds from step T21 to step T22, and it is determined whether or not the shift button has been turned on this time since it was previously turned off. When the shift button is pressed first, the process proceeds to step T23, and it is determined whether or not the timer is operating.

At first, since the timer is not activated, the process proceeds to step T24, where the timer is activated. In step 25, 1 is added to the number code.
When the process of FIG. 21 is repeated, if the shift button is kept pressed, N is returned in step T22, and the number code does not change.
When the process of FIG. 21 is repeated, when the shift button is turned off, the process proceeds from step T21 to step T31. Steps T31 and after will be described later.

When the shift button is pressed again after the shift button is turned off, the process proceeds from Y at step T21, Y at T22, Y from T23 to T25, and 1 is added to the number code.
After the number of times the shift button has been operated is stored in the number code, when the lock / unlock button is pressed (Y of T1, T3), a request signal is transmitted in the processes of steps T2, T4 to T10.
In this example, T11 is inserted before step T5, and the frequency code is read out. Accordingly, the request signal transmitted in step T10 is as shown in FIG. 20, and the number of times the shift button is pressed is included in the number code.

When the shift button is turned off, the process proceeds to step T31, and it is determined whether or not the count value of the timer is 5 seconds or more.
This timer starts operating at T24. If the lock / unlock button is not pressed after the shift button is turned off, the timer is stopped after 5 seconds have elapsed (Y in T31) (T32), and the frequency code is reset to 00 (T35).
As a result, even if the shift button is pressed due to an erroneous operation, the number code is reset after 5 seconds. Therefore, it is possible to prevent an erroneous request signal from being transmitted.

  Further, after the shift button is operated, when the lock / unlock button is operated and the transmission of the request signal is made normal, in the next process, the previous lock / unlock button 4, Since it is determined that 5 has been operated, the process proceeds to step T35, where the number code is reset.

By the above processing, the relationship between the operation of each button 4, 5, 11 and the request signal is as follows.
When the lock / unlock buttons 4 and 5 are operated, lock or unlock is set to the button code. When the operation time exceeds 2 seconds, the time code is set to 1.

If the shift button 11 is operated before the lock / unlock button is operated, the number of times is set in the number code. The number code is reset after the lock / unlock button is operated and a request signal is transmitted.
When 5 seconds elapses without operating the lock / unlock button after the shift button is operated, the frequency code is reset.

The operation of the receiver 2 in this example will be described with reference to FIGS.
The overall flow of the receiver 2 is as shown in FIG. 5 of the first embodiment. The relationship between FIG. 5 and FIGS. 23 to 26 is as follows.
FIG. 5 Step S1 (Flag Operation): FIGS. 23 and 24
FIG. 5 Step S2 (lock / unlock control): FIG.
FIG. 5 Step S3 (door opening / closing control): FIG.

The flag operation will be described with reference to FIGS.
When the request signal is received, the number of shifts of the number code is stored (L1).
It is determined whether the request signal is a lock signal (L2). If Y here, it is determined whether or not reception is the first time (L3). If reception is the first time, “1” is set in the lock request flag (L4), and the number of shifts is determined (L5). On the other hand, if it is determined in step L3 that the second time or later, the process proceeds directly to step L5.

If the number of shifts is 0 (0 in L5), it is determined whether the lock signal has continued for 2 seconds or longer (time code is “1”) (L6). If N here, the door open / close flag is not operated. If Y, the first and second sliding door closing request flags are set to “1” (L7, L8).
If the number of shifts is 1 (1 in L5), the first sliding door closing request flag is set (L9), and the second sliding door opening request flag is reset (L10). If the number of shifts is 2 (L5-2), the first door closing request flag is reset (L11), and the second door opening request flag is set (L12).

  If the reception request signal is not a lock signal in step L2, it is determined in step L12 whether or not the lock signal was received in the previous process, that is, whether or not it is immediately after the lock button is turned off (L13). . If Y here, the stored number of shifts is reset to “0” (L14), and the process proceeds to FIG. Also, if the received signal is not a lock signal and is not a lock signal, the process proceeds to FIG.

When the processing proceeds to FIG. 24, it is determined whether or not the received signal is an unlock signal (L22). If Y here, similarly to the processing of FIG. 23, the unlock request flag is operated (L24), and the opening / closing request flags of the first and second doors are operated (L27 to L32).
If the received signal is neither a lock signal nor an unlock signal (N of L1 and L22), whether or not the unlock signal was received in the previous process, that is, immediately after the unlock button is turned off. Is determined (L33). In the case of Y, after resetting the number of shifts (L34), the first door opening request flag is reset (L35), and the second door closing request flag is reset (L36).

The lock / unlock control will be described with reference to FIG.
It is determined whether the lock / unlock request flag is 1 (M1, M21). If the lock request flag is “1” (Y in M1), it is determined whether or not all the doors 6 to 9 and 12 are closed (M2). If there is even one open door, the lock request flag is reset (M3). If all the doors are closed, the doors are locked (M4), the lock request flag is reset (M5), the first and second door close request flags are reset (M6, M7), and the answerback is performed (M8). ).

If the unlock request flag is 1 (Y in M21), the door is unlocked (M22), the unlock request flag is reset (M23), and the answer back is performed (M24).
If neither of the lock / unlock request flags is “1”, the lock / unlock process is not performed.

The opening / closing control of the sliding door will be described with reference to FIG.
Whether the first door closing request flag is “1” (N1), whether the first door opening request flag is “1” (N11), or whether the second door closing request flag is “1” (N21). Then, it is determined whether or not the second door opening request flag is “1” (N31). If neither is “1”, the door opening / closing control of FIG. 26 is not performed.

If the first door close request flag is “1” (Y of N1), it is determined whether or not the first door is closed (N2). If N, the first door is driven to close (N3) and the buzzer sounds intermittently (N4).
When the first door is closed (Y in N2), the first door close request flag is reset (N5), and the lock request flag is set (N6). Thereby, after all the doors are closed, the doors are locked in step M2 (FIG. 25).

If the first door opening request flag is “1” (Y of N11), it is determined whether or not the first door is fully opened (N12). If N, the first door is driven to open (N13), and the buzzer is intermittently driven (N14).
When the first door is fully opened (Y of N12), the first door opening request flag is reset (N15).

  If the second door close request flag is “1” (Y of N21), when the second door is not closed (N of N22), the second door is driven to close (N23) and the buzzer is sounded (N24). ). If the door is closed (Y in N22), the second door close request flag is reset (N25), and the lock request flag is set (N26).

If the second door opening request flag is “1” (Y of N31), the second door is driven to open (N32), and the buzzer is intermittently driven (N33). Further, it is determined whether or not the second door is fully opened (N34). If the second door is opened fully, the second door opening request flag is reset (N35).
In this example, the door opening / closing request flag is set without requiring the 2-second continuation when the number of shifts is 1 or more in steps L5 and L25. However, for the safety, the 2-second continuation may be inserted as a requirement.
