senses there is object within 120cm
behind the vehicle during reverse, it
will send out beeps to warn the
driver. This system is merely an
auxiliary system.
The reverse radar determines
whether there is the obstacle in the
reverse direction of vehicle and
indicates the distance from the
nearest
obstacle according to
ultrasonic ranging principle and
computer data fuzzy processing
technology. When the reverse gear
is engaged, the reverse gear switch
is opened and reversing light is on,
the controller receives reversing

(with three probes) will send out
ultrasonic signal.

ultrasonic echoed signal, it will
transmit this signal to the controller,
which will analysis and process the
signal, judging whether there is
obstacle within the sensing distance
as well as the distance of the nearest
