System Operation Specification
- INIT mode
- System initializing time is 500 ms after IGN1+ R Gear.
- RPAS recognizes ID and sets the sensor ID up during initialization.
- RPAS activates each sensor and then executes the diagnosis after finishing initialization of BCM
- "RPAS Starting buzzer" is normally worked, when sensor does not send an error message and after finishing error diagnosis.
- If any failure is received from the any sensors, "RPAS 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.
- Buzzer for sensor failure is operated once, but display is shown continuously until it is repaired completely.
- NORMAL Mode
- LIN communication starts and keeps the routine after IGN1 ON+R gear
- BCM 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 500ms of R gear shifting at 300ms intervals.
- After initialization, normal mode starts 100ms later after finishing alarm output.
- Alarm for obstacles is divided into 3 levels.
The first and second are intermittent sound, and the third alarms continuously
- The efficient vehicle speed of RPAS operation is under 10 Km/h.
- Refer to 'Digital PAS Project LIN communication' for the more detailed communication specification.
