The control system of an automatic transmission provides various programs of work of a transmission. Depending on actions of the driver or from traffic conditions of the car gets out or economic, i.e. directed on economy of fuel the program, or the active program which very conditionally it is possible to call "sports".
The choice of the program of work of a transmission is carried out automatically depending on 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 a pedal of an accelerator is carried out rather sharply. 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 of a transmission. At a choice of a "sports" mode engine capacity reserves thanks to some delay of switching on higher transfer are completely used.
Prevention
Depending on resistance to movement, for example, at towage of the trailer or movement in the mountain district, such program that by switching on lower transfer to provide the increased traction effort on driving wheels automatically gets out and by that to avoid continuous gear shifting.
