Protecting The Overheated Motor
In order to protect the
overheated Panoramaroof motor by continuous motor operation, the
Panoramaroof ECU controls the Run-time and Cool-time of motor as
followings;
1. |
The Panoramaroof ECU detects the Run- time of
motor |
2. |
Motor can be operated continuously for the 1st
Run-time(120 ± 10sec.). |
3. |
Motor which is operated continuously stops
operating after the 1st Run-time(120 ±
10sec.). |
4. |
And 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. |
Motor which is operated continuously 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 which is limited for protecting the
overheated motor 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. |
