System Operation Specification

Initial mode - Front sensor
1. System initializing time is 500 ms after IGN1+ initial D Gear + below 10 Km/h.
2. PDW recognizes LID and sets the sensor ID up during initialization.
3. PDW activates each sensor and then executes the diagnosis after finishing initialization of IPM (IBU).
4. PDW Starting buzzer" is normally worked, when sensor does not send an error message and after finishing error diagnosis.
5. If any failure is received from the any sensors, PDW Starting Buzzer" does not work but the failure alarm is operated for a moment.
  If you have display option, warning sign is also shown on it.
6. Buzzer for sensor failure is operated once, but display is shown continuously until it is repaired completely.
7. IPM (IBU) memorizes the completed initializing status of front sensor until IGN 1 is OFF. It doesn't activate initializing when next D gear input.
8. In case of PDW SW OFF, system initializing does not be activated.
9. If PDW switch is ON like as below status, it activates initializing.
  - PDW switch OFF when IGN1 is On.
  - PDW switch ON when vehicle speed is below 10 km/h
10. Initializing has nothing to do with parking brake operation.
Initial mode - Rear sensor
1. System initializing time is 500 ms after IGN1+ initial R Gear.
2. PDW recognizes LID and sets the sensor ID up during initialization.
3. PDW activates each sensor and then executes the diagnosis after finishing initialization of IPM (IBU).
4. PDW Starting buzzer" is normally worked, when sensor does not send an error message and after finishing error diagnosis.
5. If any failure is received from the any sensors, PDW Starting Buzzer" does not work but the failure alarm is operated for a moment.
  If you have display option, warning sign is also shown on it.
6. Buzzer for sensor failure is operated once, but display is shown continuously until it is repaired completely.
7. IPM (IBU) memorizes the completed initializing status of rear sensor until IGN 1 is OFF. It doesn't activate initializing when next R gear input.
8. Initializing has nothing to do with parking brake operation.
Normal mode - Front sensor
1. Lin communication starts and keeps the routine after IGN1 ON+D gear + below 10 km/h.
2. After initializing, the routine starts at once without PDW starting warning sound.
3. Alarms of obstacle consists of 3 level 1, 2, 3 step and 1, 2 alarm sounds intermittently and 3 alarm sounds continuously. 1 level alarm doesn't exist in the front ultrasonic sensor.
  - Type with display
    - 2 level alarm: Display is only operated without alarm.
    - 3 level alarm: Alarm + Display
  - Type without display: Alarm only
4. In display, the data of each sensor is sent from IPM (IBU) to display, for example cluster. CAN communication is used for transmission and maximum gateway time is 50 ms.
5. The efficient vehicle speed of RPDW operation is under 10 Km/h.
6. It doesn't work at PDW SW OFF.
7. It has nothing to do with parking brake operation.
8. Operation doesn't start or stops at gear N, P.
Normal mode - Rear sensor
1. Lin communication starts and keeps the routine after IGN1 ON+R gear
2. IBU send a message once to each sensor for operating request to check the initial status of the system and four sensors response at a time. At this time, if there is no problem, the alarm starts after 500 ms of R gear shifting at 300 ms intervals.
3. After initialization, normal mode starts 100 ms later after finishing alarm output.
4. Alarm for obstacles is divided into 3 levels.
  The first and second are intermittent sound, and the third alarms continuously
5. In display, the data of each sensor is sent from IBU to display, for example Cluster. CAN communication is used for transmission and maximum gateway time is 50 ms.
6. It has nothing to do with vehicle speed.
7. When PDW SW is OFF, if gear R signal is inputted, PDW SW is changed to ON.
8. It has nothing to do with parking brake operation.
9. Operation doesn't start or stops at gear N, P.
