Abstract
The actuating arrangement includes a torque transmitting system that includes a first device for initiating, discontinuing or regulating the transmission of torque. A transmission includes a second device for initiating a gear shifting operation within one of a plurality of gear shifting paths. The transmission further includes a third device for initiating the gear ratio selecting operation among the gear shifting paths. An electronic control unit is operatively connected to at least one actor. The at least one actor activates in a predetermined manner, one of the first device, second device and third device for the initiation of the transmission of torque, gear shifting or gear ratio selecting operation.
Claims13
A method of initiating the operation of an actuating arrangement for a motor vehicle having an engine, a control unit for said engine, a torque transmitting system and a transmission, comprising the steps of:
- initiating, discontinuing or regulating the transmission of torque by said torque transmitting system;
- initiating a gear shifting operation within one of a purality of gear shifting paths within said transmission;
- initiating a gear ratio selecting operation between said gear shifting paths in said transmission;
- regulating one of the operations including transmission of torque, gear shifting and gear ratio selecting;
- and
- initiating, by way of said control unit, an increase of engine torque when the motor vehicle is creeping.
