Method for selecting a gear

A method for balancing clutch wear in a dual clutch transmission, the transmission comprising a first transmission mechanism arranged to transmit mechanical driving force from an output shaft of a prime mover and a first input shaft and by putting any one gear of a first set of gears of the first transmission mechanism in an engaged state to connect the first input shaft to ground engaging members;

• a second transmission mechanism arranged to transmit mechanical driving force from the output shaft of the prime mover and a second input shaft and by putting any one gear of a second set of gears of the second transmission mechanism in an engaged state to connect the second input shaft to the ground engaging members;
• a controllable first clutch unit arranged to bring the output shaft of the prime mover and the first input shaft into engagement with each other;
• a controllable second clutch unit arranged to bring the output shaft of the prime mover and the second input shaft into engagement with each other, and an electronic control unit arranged to control gear selection of the first transmission mechanism and the second transmission mechanism and actuation of the first and second clutch unit, and wherein gears in the first set of gears of the first transmission mechanism and in the second set of gears of the second transmission mechanism range from a lowest gear to a highest gear, the method comprising the control unit performing the steps of:
• determining which of the first and second clutch unit is subjected to a greater amount of accumulated wear based on which one of the first and second clutch units is being used for a highest gear;
• and
• selecting a gear for launch actuated by a clutch unit of the first and second clutch unit that is subjected to a lesser amount of accumulated wear than the clutch unit that is determined to be subjected to the greater amount of accumulated wear, which gear is a higher gear than a lowest gear in the dual clutch transmission.
