CAUTION
1. In case of bumpers fitted with
ultrasonic sensors (4 Nos), the
system performance is dependent
on the reflection of ultrasonic waves
from the obstacle.
2. System cannot sense
a) Wire mesh, handrail, small
objects & some obstacle which are
coming too much below or too
much above the bumper level.
b) Ostacles like cotton, wool, foam,
textile or spongy surface which will
absorb ultrasonic waves easily.
c) Pot holes or the trenches or
drainages which are below the
ground level.
3. System may give wrong signal
on reversing :
a) When the vehicle on grasslands
& bumpy roads.
b) While vehicle moving from plain
ground to slope like backing up
downhill or vice versa.
c) When the bumper is tilted more
than the normal position or when
the vehicle is heavily overloaded.
d) When the temperature of the
obstacle is high as hot surfaces
reflect fewer sound waves less
than cold surfaces.
e) If there is an excessive increase
in humidity as it increases the
sound speed (max. by 2%) as
compared to dry air.
