•
System may give false signal while the vehicle moves from plain
ground to a slope terrain and vice versa
•
System may give false signal by sensing the ground when the
bumper is tilted more from the normal position or when the
vehicle is heavily overloaded
•
System may give false signal an alarm during heavy rain, snow
and heavy wind conditions
•
The shape of the obstacle may prevent a sensor from detecting
it. Some obstacles for example as follows:
– Sharply-angled objects
– Tall or curved curb
– Low obstacles (with height of 40 cm above ground level)
– Tall obstacles with upper sections projecting outwards in the
direction of the vehicle
•
Depending
upon
the
shape
of
the
obstacle
and
other
environmental factors, the detection distance may shorten or
detection may be impossible
•
Obstacles may not be detected if they are too close to the
sensor
•
Thin posts or objects lower than the sensor may not be detected
when approached, even if they have been detected once
•
Because of other ultrasonic sources, sensor may give false
alarm for e. g., sweeping machines, high pressure steam
cleaners and neon lights
•
Due to vehicle horns, motorcycle engines, air brakes of large
vehicles, or other loud noises producing ultrasonic waves, the
vicinity of the vehicle is noisy. It may cause sensor to give false
alarm

Reverse parking assistance system is provided to aid the driver
while parking the vehicle in reverse at a speed of less than 8kmph.
While reversing, RPAS will detect the obstacles at the rear side of
the vehicle within the sensing zone, which cannot be viewed through
the internal rear-view mirror and the outside rear view mirrors. The
RPAS will then alert the driver by a beep sound and display about
the location of the detected obstacle. The alert sound level will vary
proportional to the distance. Smaller the distance shorter the
interval between the beeps.
