Protecting Motor From Overheating
In order to protect the
sunroof motor from overheating from continuous motor operation, the
sunroof ECU controls the Run-time and Cool-time of the motor as
follows:
| 1. |
The Sunroof ECU detects the Run- time of
motor |
| 2. |
Motor can be operated continuously for the 1st
run-time(120 ± 10sec.). |
| 3. |
The continuous operation of motor stops after
the 1st Run-time(120 ± 10sec.). |
| 4. |
Then Motor is not operated for the 1st
Cool-time(18 ± 2sec.). |
| 5. |
Motor is operated for the 2nd Run-time(10 ±
2sec.) at the continued motor operation after 1st Cool-time(18 ±
2sec.) |
| 6. |
The continuous operation of motor stops
operating after the 2nd Run-time(10 ±
2sec.) |
| 7. |
Motor is not operated for the 2nd Cool-time(18
± 2sec.). |
| 8. |
Motor repeats the 2nd run-time and 2nd
cool-time at the continued motor operation.
| A. |
In case that motor is not operated
continuously, the run-time is
increased. |
| B. |
The Run-Time of motor is initialized to
"0" if the battery or fuse is reconnected after being
disconnected, discharged or
blown. |
T1 : 120 ± 10 sec., T2 : 18 ± 2
sec.,
T3 : 10 ± 2 sec., T4 : 18 ± 2
sec. |
