Borrego 2WD V6-3.8L (2009)
Parking Assist Control Module: Description and Operation
Description
When reversing, the driver is not easy to find objects in the blind spots and to determine the distance from the object. In order to provide the driver
safety and convenience, back warning system will operate upon shifting to "R" Ultrasonic sensor will emit ultrasonic wave rearward and detect the
reflected wave. Control unit will calculate distance to the object using the sensor signal input and output buzzer alarm in three steps (first, second and
third alarm).
Alarm Range
Upon detecting an object at each range out of 3 ranges as stated below within the operation range, it will generate alarm.
First alarm : Object comes near to the sensor located at the rear of vehicle, within 81-120cm ± 15cm
Second alarm : Object comes near to the sensor located at the rear of vehicle, within 41-80cm ± 10cm
Third alarm : Object comes near to the sensor located at the rear of vehicle, within 40cm ± 10cm
NOTE:
1. Time tolerance of the above waveform : Time ± 10%
2. At nearer distance than 40cm, detection may not occur.
3. Alarm will be generated with vehicle reversing speed 10km/h or less.
For moving target, maximum operation speed shall be target approach speed of 10km/h.
4. When the vehicle or the target is moving, sequential alarm generation or effective alarm may be failed.
5. False alarm, or failure of the alarm to trigger may occur in the following conditions.
-
Irregular road surface, gravel road, reversing toward grass.
-
Horn, motor cycle engine noise, large vehicle air brake, or other object generating ultrasonic wave is near.
-
When a wireless transmitter is used near to the sensor.
-
Dirt on the sensor.
-
Sequential alarm may not occur due to the reversing speed or the target shape.
