METHOD FOR SELECTING A GEAR

摘要

The invention relates to a method for balancing clutch wear in a dual clutch transmission (13), the transmission comprising a first transmission mechanism (23) arranged to transmit mechanical driving force from an output shaft (20) of the internal combustion engine (12) to a first input shaft (25) and to put any one of a first set of gears in an engaged state to connect the first input shaft to the ground engaging members (16); a second transmission mechanism (24) arranged to transmit mechanical driving force from the output shaft (20) of the internal combustion engine (12) to a second input shaft (26) and to put any one of a second set of gears in an engaged state to connect the second input shaft to the ground engaging members (16); a controllable first clutch unit (21) arranged to bring the output shaft of the internal combustion engine and the first input shaft into engagement with each other; a controllable second clutch unit (22) arranged to bring the output shaft of the internal combustion engine and the second input shaft into engagement with each other, and an electronic control unit (15) arranged to control gear selection and clutch unit actuation. The method involves performing the steps of determining which clutch unit (21, 22) is subjected to the most accumulated wear and selecting a gear actuated by the other clutch unit during launch of the vehicle.
