Hyundai Palisade: Parking Distance Warning (PDW) / Description and operation

Hyundai Palisade (LX2) 2020-2024 Service Manual / Advanced Driver Assistance System (ADAS) / Parking Distance Warning (PDW) / Description and operation

Description
PDW consists of 8 sensors (front : 4 units, rear : 4 units) that are used to detect obstacles and transmit the result in three separate warning levels, the first, second and third to IBU via LIN communication.
IBU decides the alarm level by the transmitted communication message from the slave sensors, then operates the buzzer or transmits the data for display.

System Operation Specification
Initial mode
1.
System initializing time
PDW-F : 500ms after IGN1+ initial D Gear + below 10 Km/h
PDW-R : 500ms 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.
Hyundai Palisade. Description and operation   
Buzzer for sensor failure is operated once, but display is shown continuously until it is repaired completely.
6.
IBU memorizes the completed initializing status of sensor.
Normal mode
7.
PDW-F : Lin communication starts and keeps the routine after IGN1 ON+D gear + below 10 km/h.
PDW-R : Lin communication starts and keeps the routine after IGN1 ON+R gear
8.
After initializing, the routine starts at once without PDW starting warning sound.
9.
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.
10.
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 50ms.
11.
The efficient vehicle speed of PDW operation is under 10Km/h.
12.
Operation doesn't start or stops at gear N, P.
