The operation and operation of the keyless entry system thus constructed will be described below. First,
When the lock button 30 is pressed once, an ID code and a lock command are transmitted from the transmitter 2. When the ID code and the lock command are received by the receiver 4 and the ID code is collated and confirmed, the lock signal S
L is transmitted to the ECU 6. After that, the drive signal DL is supplied from the ECU 6 to the door lock motor 10, and the automatic door locks 9 of all the doors 8 are locked.

When the unlock button 32 is pressed once, the transmitter 2 transmits the same ID code and unlock command as above. Then, the ID code and the unlock command are received by the receiver 4, and when the confirmation of the ID code is completed, the unlock signal SUL is transmitted to the ECU 6. In this case, the drive signal DUL is supplied from the ECU 6 to the door lock motor 10, and the automatic door locks 9 of all or some of the doors 8 are unlocked.

When the trunk button 34 is pressed twice in succession and the transmitter 2 transmits the ID code and the trunk open command, the receiver 4 transmits the trunk open signal ST to the ECU 6 after confirming the ID code. It Then, the drive signal DT is supplied from the ECU 6 to the trunk opener 10, and the trunk lid is opened.

Further, the lock window 30 and the unlock button 32 can be used to open and close the power window 13 and the electric sunroof 17a, and their operation and action will be described below with reference to FIGS. 2 and 3. Figure 2 shows E
It is a flowchart which shows the control routine of the power window up control which CU6 performs, and FIG. 3 is a flowchart which shows the control routine of the pinch prevention control of the power window 13 which ECU6 performs with power window up control.

First, the power window up control of FIG. 2 will be described. In this power window up control, it is premised that the automatic door locks 9 for all the doors 8 are completely locked. Therefore, step S
At 10, it is judged whether or not the lock signal SL is received. When the determination result is No (negative), the process returns to the original and the execution of step S10 is repeated. On the other hand, the determination result is Ye
When it is determined that the lock signal SL is received in s (affirmative), the process proceeds to step S12, the drive signal DL is output to the door lock motor 10, and the automatic door locks 9 of all the doors 8 are locked.

Step S14 is a step of setting the timer TM1 for the power window, and the ECU 6
The elapsed time after receiving the lock signal SL is measured.
In step S16, the timer TM set as described above is used.
It is determined whether the measured time TM1 of 1 is within the predetermined time t1. This predetermined time t1 is, for example, 25 seconds (t1 =
25 sec) and the power window 13 described later
Is the time limit at which the closing operation can be performed.

The determination result of step S16 is No (negative).
If it is determined that the measured time TM1 has passed the predetermined time t1 (25 sec), the process returns to step S10. On the other hand, if the determination result in step S16 is Yes (affirmative) and it is determined that the predetermined time t1 (25 sec) has not yet elapsed, the power window 13 is within the range in which the closing operation can be performed, and the next step Proceed to S18.

Steps S18 to S24 are steps for performing the closing operation of the power window 13.
In step S18, it is determined whether or not the lock signal SL is received again in the same manner as the determination in step S10. Then, the determination result of step S18 is No (negative)
Then, if the lock signal SL is not received again,
The execution of step S16 is repeated. On the other hand, step S1
When the determination result of 8 is Yes (affirmative) and it is determined that the lock button 30 is pressed and the lock signal SL is received again, the process proceeds to step S20, and the door lock motor 10 is operated similarly to step S12. The drive signal DL is output to. As a result, the automatic door lock 9 is reliably locked together with the execution of step S12.

In step S22, it is determined whether or not the power window up signal SPU has been received. The power window up signal SPU is a signal transmitted when the lock button 30 is once pushed to receive the lock signal SL and then the lock button 30 is continuously pushed for a predetermined time tPU (for example, 2 sec) or more. This power window up signal SPU is one of the identification signals SD in FIG. 1 in which various control signals are coded and transmitted, and here,
The coded power window up signal SPU is transmitted to the ECU 6 as the identification signal SD.

The determination result of step S22 is No (negative).
When the power window up signal SPU is not received at, that is, the lock button 30 is continuously operated for a predetermined time tPU.
If the button is not pressed for more than (2 sec), step S
The execution of 16 is repeated. On the other hand, when the determination result of step S22 is Yes (affirmative), the lock button 30 is continuously pressed for the predetermined time tPU (2 sec) or more, and the ECU 6 receives the power window up signal SPU, the process proceeds to step S24. move on.

At step S24, the ECU 6 supplies the power window motor 14 with the power window up drive signal DPU. At this time, the ECU 6 also supplies the sunroof close drive signal DSC to the sunroof C / U 16. Therefore, the window glass 15 and the electric sunroof 17a are simultaneously closed based on the power window up signal SPU. As a result, the window glass 15 and the electric sunroof 17a that have been left unclosed can be reliably closed by remote control. The window glass 15 that is already closed among the plurality of window glasses 15 and the electric sunroof 17a that is closed are maintained in the closed state.

The next step S26 is a step of setting the power window stop timer TM2,
The ECU 6 measures the elapsed time after receiving the power window up signal SPU. In step S28, the time TM of the timer TM2 set as described above is measured.
It is determined whether or not 2 is within the predetermined time t2. The predetermined time t2 is set to, for example, 10 seconds (t2 = 10 seconds), which is a time limit during which the power window 13 can be stopped as described later.

When the measured time TM2 is within the predetermined time t2 (10 sec) which is the time limit,
When the lock button 30, unlock button 32, and trunk button 34 of the transmitter 2 are pressed, the lock signal SL
When the unlock signal SUL and the trunk open signal ST are supplied to the ECU 6, the power window motor 14
The ECU 6 is programmed to interrupt the power window up drive signal DPU and the sunroof close drive signal DSC supplied to the sunroof C / U 16 and the sunroof C / U 16.

The determination result of step S28 is No (negative).
If the predetermined time t2 has elapsed, the process returns to step S10 without doing anything. On the other hand, the determination result of step S28 is Yes (affirmative), and the predetermined time t2 (10 sec)
If has not yet passed, the process proceeds to step S30. In step S30, it is determined whether or not at least one of the lock signal SL, the unlock signal SUL, and the trunk open signal ST is received. If the determination result is No (No) and none of the lock button 30, unlock button 32, and trunk button 34 is pressed, step S28
Return to

On the other hand, the determination result of step S30 is Yes.
In the case of (affirmative), that is, the power window up signal S
The time measured TM2 after receiving the PU is the predetermined time t2 (1
During 0 sec), any one of the lock button 30, the unlock button 32, and the trunk button 34 is pressed again, and any one of the lock signal SL, the unlock signal SUL, and the trunk open signal ST is pressed. If it is determined that the ECU 6 has received this signal, the process proceeds to step S32.

In step S32, in response to the determination result in step S30, the power window up drive signal DPU and the sunroof close drive signal DSC supplied to the power window motor 14 and the sunroof C / U 16 are
It will be interrupted based on the above program. As a result, the window glass 15 on the way up and the electric sunroof 17a operating on the closing side are deactivated, and the stopped position is maintained.

As described above, the window glass 15 and the electric sunroof 17a, which are in the closing operation, are kept at the predetermined time t2 (10).
If the lock button 30, the unlock button 32, or the trunk button 34 is pressed, the power window motor 14 and the sunroof C / U can be stopped.
When the foreign matter is confirmed between the window glass 15 and the door sash 8a or between the electric sunroof 17a and the roof 17, the operation can be stopped immediately without selecting the operation button. The closing operation of the window 13 and the electric sunroof 17a can be stopped.

When the closing operation of the power window 13 and the electric sunroof 17a is temporarily stopped by executing step S32, the process returns to step S10. Therefore, when it is desired to close the power window 13 and the electric sunroof 17a, which have been stopped halfway, by remote control again, the lock button 30 may be pressed again and the process from step S10 may be repeated.

Next, the control routine of the jamming prevention control shown in FIG. 3 will be described. This trapping prevention control functions to automatically stop the operation of the power window 13 in an emergency when a foreign object is trapped between the window glass 15 and the door sash 8a. With pinch prevention control,
First, in step S50, it is determined whether or not the power window up signal SPU is received. This step S50 is executed in conjunction with step S22 of the above-mentioned power window up control routine.

The determination result of step S50 is No (negative).
In the case of, the execution of step S50 is repeated. on the other hand,
When the determination result of step S50 is Yes (affirmative) and it is determined that the power window up signal SPU is received, the process proceeds to step S52. In step S52,
Step S24 of the power window up control routine
Similarly, the power window motor 14 is supplied with the power window up drive signal DPU and the sun roof close drive signal DSC is supplied to the sun roof C / U 16.

In the next step S54, the power window 13 of either door 8 or the electric sunroof 17a.
It is determined whether or not the entrapment of the foreign matter is detected in. The case of the power window 13 will be described below. This pinching determination is executed based on the pulse signals Pa and Pb from the two pulse sensors 14a and 14b of the power window motor 14 (foreign body pinching detection means).

The ECU 6 uses the power window motor 14
Each time, the pulse signals Pa and Pb output from the pulse sensors 14a and 14b are received, and the respective pulse periods Ta and Tb are constantly monitored. Normally, when the power window motor 14 operates normally and the window glass 15 rises satisfactorily, these pulse periods Ta, Tb
Is constant. However, if foreign matter becomes caught between the window glass 15 and the door sash 8a and the window glass 15 becomes difficult to rise, the power window motor 1
The rotation of 4 becomes slower, and the pulse periods Ta and Tb become longer. Therefore, in step S54, the presence / absence of a foreign substance is pinched by observing the changes in the detected pulse periods Ta and Tb (rotation period detecting means). Specifically, the determination is performed by comparing the detected pulse periods Ta and Tb with a threshold value of a map (not shown) set in advance by experiments or the like. The threshold value of this map is variously set and corrected based on the voltage supplied to the power window motor 14 and the temperature.

Further, the ECU 6 controls the pulse periods Ta and Tb.
Based on the change rate V of the rising speed of the window glass 15
Also, a ′ and Vb ′ are obtained from the following equations (1) and (2), and the foreign matter trapping rate is also obtained by comparing the rising speed change rates Va ′ and Vb ′ with a threshold value of a map (not shown). It is possible to detect the presence / absence of inclusion. Incidentally, this threshold value is also set in various corrections based on the voltage supplied to the power window motor 14 and the temperature.

Va ′ = (Va _n−1 −Va _n ) / Ta _n (1) Vb ′ = (Vb _n−1 −Vb _n ) / Tb _n (2) where Ta _n and Tb _n are This is the pulse cycle detected this time, and Va _n-1 and Vb _n-1 are the pulse signals Pa detected previously.
, It increases the speed of the window glass 15 based on Pb, also, Va _n, Vb _n is currently detected pulse signal Pa,
A rising speed of the window glass 15 based on _{Pb, Va n-1, Vb} n-1 and Va _n, Vb _n by the following equation (3),
Calculated from (4) (operating speed detection means).

Va _n = A × 2 / Ta _n (3) Vb _n = A × 2 / Tb _n (4) This A is the unit rise distance D 0 of the window glass 15 for each rotation of the power window motor 14 (for example, , 0.74
mm / pulse), which is preset for each power window 13.

In this way, the two pulse sensors 14a,
14b, pulse periods Ta and Tb based on pulse signals Pa and Pb from 14b, and a rate V of rise rate of the window glass 15
By comparing a ′ and Vb ′ with the threshold values of the respective maps, it becomes possible to reliably detect the entrapment of foreign matter between the window glass 15 and the door sash 8a. Therefore, in step S54, it is determined that the foreign matter is trapped when either the pulse period Ta, Tb or the rising rate change rate Va ', Vb' of the window glass 15 deviates from the threshold value of each map. .

The pulse signals Pa and Pb are out of phase with each other due to the different positions of the pulse sensors 14a and 14b. By detecting which of the pulse signals is advancing or retarding. It is also possible to confirm the operating direction of the power window 13. This foreign matter pinch detection method is the same for the electric sunroof 17a.

The determination result of step S54 is No (negative).
If no foreign matter is sandwiched between the window glass 15 and the door sash 8a, the process proceeds to step S60. Step S60 is a step of determining whether or not the window glass 15 or the electric sunroof 17a is completely lifted and is in a fully closed state. The case of the power window 13 will be described below.

The detection of the fully closed state is performed by detecting the pulse signal P
This is carried out based on the number of times of rising and falling of a and Pb, that is, the count value of the number of edges Ea and Eb (rotation speed detecting means) (fully closed state detecting means). In practice, the smaller number of the edge numbers Ea and Eb is selected and used. The number of edges Ea and Eb is the window glass 1
When 5 is fully closed, the initial count value is zero,
It increases as the window glass 15 descends. Therefore, the ECU 6 determines that the window glass 15 is in the fully closed state when both the edge numbers Ea and Eb are equal to or less than the predetermined edge number E1 (for example, a value of 20) and the gap between the window glass 15 and the door sash 8a is about 15 mm or less. I am trying. The number of edges Ea and Eb are calculated by the ECU 6
Is a predetermined number of edges E1 (value 20) or less, a predetermined time t
Pulse signals Pa and P for s (for example, 0.5 sec) or more
When b is not detected, the initial count value is reset to zero. Therefore, when the window glass 15 is in the fully closed state, the edge numbers Ea and Eb are always kept at the initial count value of zero.

When the determination result of step S60 is Yes (affirmative) and it is determined that the window glass 15 is in the fully closed state, the process returns to step S50. On the other hand, step S60
When the determination result of No is No and the window glass 15 is rising, the process returns to step S54 and the determination of whether or not the jamming is detected is repeated. If the determination in step S54 is Yes (affirmative), either the pulse period Ta, Tb or the rate of change of rising speed Va ', Vb' of the window glass 15 deviates from the threshold value of the respective maps, and the window glass 15 and the door sash 8a are separated. When it is determined that the foreign matter is sandwiched in, the process proceeds to step S56.

In step S56, the rotating direction of the power window motor 14 or the operating direction of the sunroof C / U 16 is reversed to temporarily move the window glass 15 or the electric sunroof 17a at a predetermined distance D1 (for example, 150 mm).
This is a step of stopping after only operating (emergency stop means). The power window 13 will be described below.

The predetermined distance D1 (150 mm) is the predetermined number of edges E2 (for example, the value 202) and the above-mentioned A, that is, the unit rise distance D0 (0.74 mm / pulse) of the window glass 15 for each rotation of the power window motor 14. ) And the product. Therefore, in this step S56, E
The number of edges Ea, E at the time when the CU 6 detects the entrapment of foreign matter
After the window glass 15 is once lowered until the count value from b reaches the predetermined edge number E2 (value 202),
Stop this. At this time, the operations of not only the power window 13 having a foreign object sandwiched therein but also the power windows 13 of all doors and the electric sunroof 17a are similarly stopped.

Thus, once the window glass 15 is lowered, the foreign matter sandwiched between the window glass 15 and the door sash 8a is not left as it is. This operation is the same for the electric sunroof 17a and the electric sunroof 17a and the roof 17a.
When foreign matter is detected to be caught between the electric sunroof 1
Not only 7a but all the power windows 13 once reversely operate and then stop.

By the way, by executing step S56,
When the power window 13 or the electric sunroof 17a is stopped, the execution of step S56 of the pinch prevention control is prioritized, and the step S24 and subsequent steps of the power window up control described above are not executed. Therefore, when reactivating the stopped power window 13, the lock button 30 of the transmitter 2 is operated again.

As described above in detail, foreign matter is caught between the window glass 15 and the door sash 8a or between the electric sunroof 17a and the roof 17 when the power window remotely operated by the keyless entry system is closed. When is detected, the power window 13 and the electric sunroof 17a are immediately inverted and then stopped, so that the safety of the remote operation of the power window 13 and the electric sunroof 17a can be improved.

By the way, in this keyless entry system, similarly to the above power window up control,
Power window down control for opening the power window 13 after unlocking the automatic door lock 9 can also be performed. Here, in response to the operation of the unlock button 32, the drive signal DPD is supplied from the ECU 6 to the power window motor 14 to open the power window 13, and the opening operation of the power window 13 can be emergency stopped as described above. However, a detailed description of the operation and operation is omitted here.
