THE GENERAL DATA

Work programs

The control system of an automatic transmission provides various programs of work of a transmission. Depending on actions of the driver or from car traffic conditions gets out or economic, i.e. Directed on economy of fuel the program, or the active program which it is possible to name rather conditional "sports".

The choice of the program of work of a transmission is carried out automatically depending on a kind of work of the driver with an accelerator pedal.

At the slowed down or normal kind of work with an accelerator pedal thanks to early inclusion of higher transfers and late transition to lower transfers there is a possibility of economy of fuel.

The so-called "sports" program of work of a transmission gets out when management of an accelerator pedal is carried out sharply enough. Thus it is necessary to press an accelerator pedal not so vigorously needlessly not to pass a threshold of pressure upon an accelerator pedal behind which there is the compulsory anticipatory inclusion of lower transfer provided in a control system by a transmission. At a choice of a "sports" mode reserves of capacity of the engine thanks to some delay of switching on higher transfer are completely used.

Depending on resistance to movement, for example, at towage of the trailer or movement on lifting, such program that by switching on lower transfer to provide the raised traction effort to driving wheels automatically gets out and by that to avoid a constant gear change.

Sekventalnyj mode of switching

Presence секвентального a gear change mode (the system "типтроник") gives the chance to the driver to switch transfers manually.

For transition to the program of manual switching it is necessary to translate the selector from a position "D" to the right. Transition can be carried out both on the motionless car, and at movement. At a gear change on the display there are figures "5, 4, 3, 2, 1". The transfer included at present is shown.

Selector little push forward () transfers upwards consistently join, and a little push back (-) – is consecutive downwards.

At car dispersal there is an automatic inclusion 2nd, 3 and 4th transfers shortly before the moment of achievement by the engine of as much as possible admissible frequency of rotation.

If the driver makes switching from any transfer on lower transfer, the block of management by a transmission will include this lower transfer only when there will be no danger перекрутки the engine.

Selector blocking

The selector in positions "Р" and "N" at the included ignition is blocked. For a conclusion of the selector from these positions it is necessary to press a brake pedal and to press on the button in the selector handle. Thanks to it there is no situation when on imprudence one of transfers and the car can be included will absolutely uncontrolledly get under way from a place.

In a design of an automatic transmission the delay device is provided that at transition from one position to another through a position "N" (for example, from "R" to "D") the selector has not been blocked. Thanks to it, "rocking" of the got stuck car is possible. Only when the selector at not pressed brake pedal is more than one second in a position "N", there is a selector blocking.

At speed of movement above 5 km/h selector blocking in a position "N" is automatically switched off.
