Electric equipment of system of comfort

THE GENERAL DATA

Under an electric equipment of system of comfort of the car set of various devices, as that the uniform lock, remote control, adjustment of a mirror of an exterior, electric window raiser, internal illumination, management сдвижной the roof panel, the anticreeping alarm system, and also memory of seats and a mirror means.

The uniform lock is set in motion by the electric motor. It consists of one central monitor, two or four door monitors, four blocks of lock-out of doors, and also engines and switches for locks of a cover of a luggage carrier or a back door. Other data concerning the uniform lock are resulted in subsection the Uniform lock – the general data and vacuum hoses.

Data exchange between monitors occurs through the so-called CAN-tyre (on switched lines). CAN is reduction of words Controlled Area Network and means that monitors are connected with each other in one network. For example, communication of the central monitor with a monitor a door occurs on two wires. Without the CAN-tyre communication would be carried out by means of 14 cables. Thanks to it the electronic system takes a few places and weighs a little.

Monitors doors form together with electric motors Glass lifts the block. The block operates following functions electric Glass lifts:

– Automatic lifting and lowering of door glasses.
– A hand control lifting and lowering of door glasses when press the switch of a door of the driver.
– The termination of movement of glass as soon as the switch is pressed the second time.
– The windowpane can be operated during 10 mines after ignition deenergizing.
– Lock-out of windows by a door key.
– Protection against a jamming in area from 4 to 200 mm below the top window consolidation. If glass at movement upwards meets an obstacle, for example, with a hand, the protection mechanism returns glass in former position. Protection against a jamming consists of the gauge of the Hall located on a payment of a monitor by a door and a ring magnet on an axis of the engine. By means of the gauge of the Hall the monitor a door distinguishes reduction of number of turns of the engine (at occurrence of an obstacle to movement) and changes polarity of pressure on the engine, i.e. includes a backspacing.

ATTENTION

Protection against a jamming can be switched off, if window lifter, after a glass stop, joins twice during 5 with.

After loss of power supplies of a monitor by a door, for example, owing to switching-off of the storage battery the monitor should remember final positions of glass again. Otherwise automatic work of a window is impossible, look subsection Removal and installation of the storage battery.

The monitor a door carries out also functions of management by adjustment of a mirror of an exterior and its heating.

The central monitor is in the block of the panel of devices and carries out following functions:

– Lock-out of a cover of a luggage carrier by the uniform lock.
– Power supplies of illumination of a luggage carrier.
– Power supplies and automatic deenergizing on time of internal illumination, illumination of reading and a cosmetics lamp.
– Deenergizing later 30 with: if the key was taken out from the ignition lock, or the door opened and was again closed.
– Deenergizing later 10 mines: if ignition was switched off also one or several doors stand the opened.
– Deenergizing after 1 hour: if internal illumination has been included manually and ignition is switched off.
– Internal illumination joins automatically on 10 mines if from a monitor a safety pillow the blow signal arrives at failure.
– The anticreeping alarm system.
– Power supplies of forward and back signals of turn.
– Power supplies of warmed back glass.
– Remote control.

Remote control has radius of action about 7 m, under favorable conditions to 10 m.

Data transmission from the transmitter on a key to the receiver in the car is displayed оптически by means of LED on the key switch. The built in storage batteries provide about 5 000 pressing.

If by switch LED pressing does not light up, it is necessary to replace batteries.

Windows and сдвижная the panel of the hatch of a roof дистанционно are not closed.

The reception aerial of remote control is in a rack And the car from outside the driver. A rack And – the first rack of a body against which the door of the driver rests.

The command remote control "opening/closing" proves to be true the central monitor by a short-term blinking. If the uniform lock opens by means of remote control and thus the door or a cover of a luggage carrier/door of a back do not open, the car is locked automatically again later 30 with.
