Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sunroof operation control device for controlling the operation of a sunroof.

[0002]

2. Description of the Related Art Conventionally, some vehicles with a sunroof are equipped with a sunroof operation control device for opening and closing the sunroof.

In this type of sunroof operation control device, in order to reduce the wiring from the operation switch to the sunroof unit, the ON / OFF state of each switch is input and the operation state is changed to the on / off state of a predetermined number of conversion signals. It is known to have a conversion unit that converts a combination and outputs the combination. With this, by simply wiring the predetermined number of signal lines corresponding to the respective converted signals output from the conversion unit between the conversion unit and the sunroof unit,
The sunroof can be driven based on the combination of the on / off states of the conversion signals input from the respective signal lines.

Further, the normal sunroof operation control device is constructed so as not to operate when the ignition switch is turned off, and is operable only when the ignition switch is turned on to prevent the battery from running down.

[0005]

However, in such a sunroof operation control device, when the signal line for transmitting the conversion signal of each switch is broken, each conversion signal is different from the operated switch. May be the same as when is operated. At this time,
Since the sunroof unit cannot determine the disconnection, it may be mistakenly recognized that a switch different from the actually operated switch has been operated, and an operation corresponding to the misrecognized switch may be performed.

Specifically, when the sunroof open switch is operated, the conversion signal SW1 of the first signal line is "O".
N ", the conversion signal SW2 of the second signal line is" ON ", the third
The conversion signal SW3 of the first signal line is set to "OFF", and when the tilt down switch is operated, the conversion signal SW1 of the first signal line is "ON" and the second signal line is The case where the conversion signal SW2 is set to “OFF” and the conversion signal SW3 of the third signal line is set to “OFF” will be described as an example.

In this sunroof operation control device, when the sunroof opening switch is pressed, as shown in FIG. 7A, the conversion signal SW1 of the first signal line is "O".
N ", the conversion signal SW2 of the second signal line is" ON ", the third
The conversion signal SW3 of the signal line is turned off, and the sunroof is opened according to the switch operation.

However, when the second signal line is disconnected, the conversion signal SW2 of the second signal line is always "OF".
Therefore, even if the sunroof open switch is pressed, the conversion signal SW1 of the first signal line is "ON" and the second The conversion signal SW2 of the signal line of is OFF and the conversion signal SW3 of the third signal line is OFF, and the sunroof unit erroneously determines that the tilt down switch is pressed, and the tilt down control is performed. I will end up.

The present invention has been made in view of such conventional problems, and even when the signal line for transmitting the state of each switch is broken, the number of wires for detecting the break is not increased. It is an object of the present invention to provide a sunroof operation control device capable of detecting disconnection.

[0010]

In order to solve the above problems, in a sunroof operation control device according to a first aspect of the present invention, an operation state of a switch for operating the sunroof is input,
A conversion unit that converts each operation state into a combination of ON / OFF states of a predetermined number of conversion signals and outputs the combination, and each conversion signal output from the conversion unit is input through a corresponding signal line and is output from each signal line. In a sunroof operation control device including a sunroof unit that drives a sunroof based on a combination of ON / OFF states of input conversion signals, all conversion signals output from the conversion unit when a start condition such as ignition switch ON is satisfied. On the other hand, all of the conversion signals input from the respective signal lines were not detected in the ON state by the sunroof unit during the predetermined time after the start condition was satisfied while maintaining the ON state for a predetermined time. In this case, a disconnection detecting means for determining that there is a disconnection is provided.

That is, when the switch for operating the sunroof is operated and the conversion unit sends a conversion signal to the sunroof unit, each signal line from the conversion unit is activated at the time of start-up of control such that the ignition switch is turned on or other starting condition is satisfied. When all of the converted signals sent from are detected to be in the ON state, it is determined to be normal, and when even one of them is not detected to be in the ON state, the disconnection detecting means determines that there is a disconnection. As a result, disconnection is detected without increasing the number of wires for detecting disconnection.

Further, in the sunroof operation control device of the present invention, when the disconnection detecting means determines that there is a disconnection, the sunroof operation inhibiting means is provided for inhibiting the operation of the sunroof.

That is, when a disconnection is detected, the operation of the sunroof is prohibited by the disconnection operation prohibiting means. Therefore, even if the combination of the converted signals is changed due to the disconnection, the malfunction of the sunroof based on the change is prevented.

Further, in the sunroof operation control device of the present invention, all the conversion signals output by the conversion unit are set to the off state when the starting condition is not satisfied, while the sunroof unit outputs all the conversion signals. When at least one of the converted signals from the respective signal lines changes to the on-state in the off-state, there is provided a transition means for transitioning from the sleep mode in which the power consumption is suppressed to the wake-up mode in which normal operation is performed. .

That is, in the sleep mode in which all of the converted signals are in the off state, it is determined that at least one of the converted signals from each signal line has changed to the on state, thereby determining whether the starting condition is satisfied. Is done. At this time,
The sunroof unit is moved from the sleep mode with low power consumption to the wake-up mode for normal operation by the transition means, so that the wake-up mode can be changed without providing additional wiring for determining the satisfaction of the starting condition such as the ignition signal. The transition will take place.

Further, even if one signal line is broken, it is possible to shift to the wake-up mode, so that the above-mentioned disconnection detection is surely performed.

When all the conversion signals SW1 to SW3 are in the "OFF" state, the sunroof unit 12 has the first to third conversion signals SW1 to SW3.
When at least one of the above is "ON", power supply to the drive circuit is started and the sleep mode is shifted to a wakeup mode in which normal operation is possible.

In addition, the ignition switch is "O".
During the predetermined time when the N "-started condition is satisfied, the first
~ All of the third conversion signals SW1 to SW3 are output as "ON" from the roof unit 11.

Then, the sunroof unit 12 has the conversion signal SW1 input from the signal lines 61 to 63.
When all the conversion signals SW1 to SW3 of SW3 to SW3 are “ON”, it is determined that there is no disconnection in each of the signal lines 61 to 63, and when all of the conversion signals SW1 to SW3 are not “ON”, that is, , Even one of the conversion signals SW1 to SW3 is "O"
In the case of FF ", it is determined that each of the signal lines 61 to 63 has a disconnection, and the disconnection check of each of the signal lines 61 to 63 is performed.

The operation of the sunroof operation control device 1 in the present embodiment having the above configuration will be described with reference to the flowchart shown in FIG.

First, the ignition on / off determination flag secured in the RAM of the microcomputer of the sunroof unit 12 is set as "OFF" to set the current state of the ignition switch to "OFF" (S1), and this ignition on / off determination flag is set to "OFF". It is determined whether or not it is "ON" (S2). At this time, since the ignition on / off determination flag is "OFF", the process proceeds to step S3 and the first to third conversion signals S from the roof unit 11 are sent.
It is determined whether or not any one of W1 to SW3 is "ON" (S3).

In this judgment, when the ignition switch is "OFF", all the conversion signals SW1 to SW3 are "OFF" as shown in FIG. 2, so that nothing is done and the process branches to the step S2. In the case where any one of the first to third conversion signals SW1 to SW3 is “ON” while maintaining the sleep mode in which the power supply to the drive circuit for the sunroof motor 71 is cut off to suppress the power consumption In the ignition on / off judgment flag,
The "OFF" flag is cleared and the current state of the ignition switch is stored as "ON" (S4).

At this time, the ignition switch is "
When the "ON" start condition is satisfied, as described above,
First to third conversion signals SW1 from the roof unit 11
~ SW3 for a predetermined time (200mS as described later)
All are output as "ON".

With this, the ignition is turned on.
The measurement by the T1 timer is started (S5), and the process proceeds to step S2. In the present embodiment,
The time measured by the T1 timer is a predetermined time of 200
It shall be set to mS.

In step S2, it is determined whether or not the ignition on / off determination flag is "ON". At this time, if the ignition on / off determination flag is the "ON" flag, it is determined whether or not the measurement of 200 mS by the T1 timer is completed (S
6) If measurement is in progress, continue monitoring whether all of the conversion signals SW1 to SW3 remain “ON” for T2 time (S).
7) After setting the sunroof operation prohibition flag set in the RAM of the microcomputer to prohibit the operation of the sunroof (S8), the process proceeds to step S9.

Here, in the present embodiment, the T2
It is assumed that the time is set to 50 mS.

The T2 time is the predetermined time 20.
It takes less than 0 ms and it is "O" due to noise etc.
The time is set to be longer than the time of N ″, and here, the time is set to ¼ of the predetermined time.

As a result, the converted signal S is generated by noise or the like.
Even when W1 to SW3 are turned “ON” for a period shorter than 50 mS, this can be canceled, and the roof unit 11 and the sunroof unit 1 can be canceled.
Even if the timing of the timer is off between 2 and
The sunroof unit 12 has conversion signals SW1 to SW3.
Is configured to be able to detect "ON" of.

In step S9, the conversion signals SW1 to SW1
It is determined whether all of SW3 are "OFF" (S
9) If all are not "OFF", the process branches to step S2. On the other hand, an ignition switch “OF” in which all of the conversion signals SW1 to SW3 are “OFF”
At the time of "F", the ignition on / off judgment flag is cleared and the state of the ignition switch is set to "OF".
After storing as F ″ (S10), the process proceeds to step S2.

In step S2, it is determined whether or not the ignition on / off determination flag is the "ON" flag. At this time, if the ignition on / off determination flag is the “ON” flag, it is determined whether or not the measurement of 200 mS by the T1 timer is completed (S6).
When the measurement of 200 mS by the T1 timer has been completed, all the conversion signals SW1 to SW3 are for a certain period during the measurement of 200 mS by the T1 timer.
It is determined whether "ON" has been continuously detected for 2 hours (S11). At this time, if all of the conversion signals SW1 to SW3 cannot be continuously detected to be "ON" for T2 time, the signal line disconnection detection flag of the sunroof set in the RAM of the microcomputer is set to "disconnect". After storing "Yes" (S12), the sunroof operation prohibition flag is set to prohibit the operation of the sunroof (S1).
3), the process proceeds to step S9. At this time, in the roof unit 11, an indicator (not shown) is turned on,
It warns of disconnection. In addition, the sunroof unit 12 does not receive the conversion signals SW1 to SW3 and does not operate the sunroof motor 71.

On the other hand, in step S11, T1
While measuring 200mS by the timer, the conversion signal SW1
When it is determined that all of SW3 can continuously detect “ON” for a certain period of time T2, the sunroof normal operation can be performed by starting the supply of power to the drive circuit for the sunroof motor 71. Shift to operation control (S14),
Then, the process proceeds to step S9. At this time, a predetermined time of 2 has elapsed after the input of "ON" from the conversion signals SW1 to SW3.
00 mS has passed.

Then, the ignition switch is "O".
This predetermined time is 200
The operation of the sunroof is prohibited during mS.

Even if the sunroof switch 2 and the ignition switch are turned "ON" at substantially the same time or when the sunroof switch 2 is operated slightly earlier, when the ignition switch is turned "ON", the starting condition is satisfied as described above. Since the operation of the sunroof is prohibited and the disconnection is detected for a predetermined time (between 200 mS),
Even if the conversion signals SW1 to SW3 are set to different combinations of conversion signals SW1 to SW3 from the sunroof switch 2 in which the conversion signals SW1 to SW3 are turned “ON” due to disconnection, the sunroof unit 12 does not malfunction the sunroof.

Incidentally, the ignition switch is "ON".
If not, the sunroof unit 12 is not in the wake-up mode, and therefore the sunroof will not operate even if the sunroof switch 2 is operated to "ON" in this state.

As described above, when the roof unit 11 sends the conversion signals SW1 to SW3 to the sunroof unit 12, the ignition unit is turned on and the roof unit 1 is activated at the start-up of the control when the starting condition is satisfied.
When all the conversion signals SW1 to SW3 sent from the signal lines 61 to 63 from No. 1 are "ON", it is judged to be normal. Is judged. Thereby, the disconnection can be detected without increasing the number of wires for detecting the disconnection.

Therefore, the cost can be reduced as compared with the case where the wire for detecting the wire breakage is added to judge the wire breakage.

Further, when the disconnection is detected, the operation of the sunroof is prohibited, so that the conversion signals SW1 to SW3 are caused by the disconnection.
Even if the "ON / OFF" combination of is changed, the malfunction of the sunroof based on this can be surely prevented.

Further, at least one of the conversion signals SW1 to SW3 from the signal lines 61 to 63 is "ON".
It is possible to determine whether or not the start condition is satisfied by detecting the change to. At this time, the sunroof unit 1
2 can be switched from the sleep mode in which the power consumption is suppressed to the wakeup mode in which the normal operation is performed.
Therefore, it is possible to shift to the wake-up mode without separately providing a wiring for determining whether the starting condition is satisfied such as an ignition signal, and it is possible to reduce the cost.

As described above, at least one of the conversion signals SW1 to SW3 from the signal lines 61 to 63 is "
By detecting the change to "ON", the wake-up mode is entered. Therefore, even if one or two signal lines 61 to 63 are disconnected, the wake-up mode can be entered. Therefore, the above-described disconnection detection can be surely executed, and therefore the maintenance and inspection of the signal lines 61 to 63 can be performed.

FIGS. 5 and 6 are timing charts showing a modification of the above-described embodiment. As shown in FIG. 5, each time the sunroof switch 2 is operated, each of the signal lines 61 is changed. To 63 conversion signals SW1 to SW3
All of the above are "ON" for 200 mS, so that the disconnection check is performed every switch operation.

In such a configuration, the second signal line 62
If the sunroof switch 2 is operated, as shown in FIG. 6, when the second signal line 6 is disconnected.
The second conversion signal SW2 from 2 is always "OFF". Therefore, it is not determined that all of the conversion signals SW1 to SW3 are "ON", and "disconnection" can be detected. This makes it possible to prohibit the subsequent operation of the sunroof.

The timing charts of FIGS. 5 and 6 are
This is an example of the case where the sunroof opening switch in the sunroof switch 2 is operated and the sunroof is slid open while the ignition switch is in the "ON" state and the sunroof can be operated. FIG. 5 shows a normal state without disconnection, and when the sunroof open switch is turned “ON”, a predetermined time (20
(Between 0 mS) All the conversion signals SW1 to SW3 are set to "ON", and after a predetermined time elapses, the sunroof open switch "ON"
The conversion signal SW1 is "ON", SW2 is "ON", S
The conversion signal is sent to the sunroof unit 12 with W3 set to "OFF".

Then, the sunroof opening switch is turned "ON".
For a predetermined time (between 200 mS), the conversion signal SW1
All the SW3 to "SW3" are "ON", and the sunroof unit to which this conversion signal is transmitted judges that there is no disconnection, and after a lapse of a predetermined time, drives the sunroof motor 71 in the normal direction to open and slide the sunroof. Let

In FIG. 6, since the second signal line 62 is disconnected as described above, when the sunroof open switch is turned "ON", the conversion signals SW1 and SW3 are converted for a predetermined time (200 mS).
Becomes "ON" and SW2 remains "OFF".
The sunroof unit to which this conversion signal is transmitted judges that the sunroof is broken and prohibits the operation of the sunroof even after a lapse of a predetermined time. Therefore, SW1 becomes "O" after a predetermined time elapses.
Even if a conversion signal of N ", SW2 is" OFF ", and SW3 is" OFF "(in this case, the tilt-down operation is normally performed without disconnection), the tilt-down operation is performed. There is no such thing.

[0064]

As described above, in the sunroof operation control device according to claim 1 of the present invention, when the switch for operating the sunroof is operated and a conversion signal is sent from the conversion unit to the sunroof unit, the ignition switch is operated. When the control is started when the start condition such as ON is satisfied,
The disconnection can be detected without increasing the number of disconnection detection wirings.

Therefore, the cost can be reduced as compared with the case where the wire for detecting the wire breakage is added to judge the wire breakage.

Further, in the sunroof operation control device of the second aspect, since the operation of the sunroof is prohibited when the disconnection is detected, even if the combination of the conversion signals changes due to the disconnection, the malfunction of the sunroof based on this is surely performed. Can be prevented.

Further, in the sunroof operation control device of the third aspect, it is possible to judge whether the starting condition is satisfied by detecting that at least one of the converted signals from the respective signal lines has changed to the ON state. At this time, the sunroof unit can be shifted from the sleep mode in which the power consumption is suppressed to the wakeup mode in which the sunroof unit is normally operated. Therefore, it is possible to shift to the wake-up mode without separately providing a wiring for determining whether the starting condition is satisfied such as an ignition signal, and it is possible to reduce the cost.

Further, even if one signal line is broken, it is possible to shift to the wake-up mode, so that the above-mentioned disconnection detection can be surely executed. Therefore, maintenance and inspection of each of the signal lines can be performed.
