1.6.3. The help at a parking ahead and behind

Fig. 1.145. The switch of the device of the help at a parking



The help device at a parking signals about obstacles ahead and behind.
At movement by a back or forward course the 8-channel device by means of ultrasonic sensor controls measures distance to an obstacle. For distance measurement in a forward and back bumper are mounted on four sensor controls (2 on the centre, 2 on each side).
Sensor controls start to react at a finding of an obstacle in distance:
– Sideways 0,60 m;
– On the centre behind 1,50 m;
– On the centre ahead of 1,00 m.

Advance
The prevention of distance to an obstacle is carried out the same as at movement by a backing. However obstacle recognition occurs on shorter distance from the car.

Maneuvering
Sound signals are temporarily disconnected, if at maneuvering transfer (for example, backing transfer / forward) is switched. However as soon as the system will register approach to an obstacle, the warning signal again will begin to sound.

Malfunction of the device
Sounding within several seconds of a continuous sound signal at inclusion of transfer of a backing or inclusion of the device by a key, and also a light-emitting diode blinking in a key testifies to malfunction of system. Presence of malfunction up to ignition deenergizing testifies that at repeated attempt of inclusion of system in a key the light-emitting diode will blink and there will be no acoustic signal.
If the system is faulty, at inclusion of the device of the help at a parking the confirming sound signal is absent.
For maintenance of working capacity of the device of the help at a parking to keep sensor controls clean and free from ice.

ATTENTION
There are "dead" zones in which sensor controls do not catch objects. Special attention turn on small children and animals as they not in each case are distinguished by sensor controls.
Low obstacles caught by sensor controls can on a measure приблежения to them cease to be fixed by system and there will be no accordingly a precautionary sound signal. Also such subjects as protecting chains, дышло the trailer, the thin varnished vertical bars or fencings are not perceived by system under certain circumstances and can lead to car damage.
