Method for self-training an automatic gear-shifting mechanism of a two-wheeled vehicle, the method comprising the steps of • detecting at least o a first speed variable, representing the rotational speed of the pedal crank of the two-wheeled vehicle, and o a torque variable, representing torque applied to the pedal crank by the rider, and o the selected gear (n) of the automatic gear-shifting mechanism, and • performing a gear-changing operation to an automatic gear in dependence on the speed variable, the torque and the selected gear (n) on the basis of a characteristic map, and • detecting a first manual gear-changing request of the rider, and • performing a gear-changing operation to a first target gear in dependence on the gear-changing request, and • modifying the characteristic map by assigning the first target gear to the detected speed variable and to the detected torque, characterized in that the method additionally includes the steps of • detecting a second manual gear-changing request after the first manual gear-changing instruction by the rider during a predetermined time period, and • modifying the characteristic map in dependence on a predetermined time period elapsing without a second manual gear-changing request being detected. the method comprising the steps of • detecting at least o a first speed variable, representing the rotational speed of the pedal crank of the two-wheeled vehicle, and o a torque variable, representing torque applied to the pedal crank by the rider, and o the selected gear (n) of the automatic gear-shifting mechanism, and • performing a gear-changing operation to an automatic gear in dependence on the speed variable, the torque and the selected gear (n) on the basis of a characteristic map, and • detecting a first manual gear-changing request of the rider, and • performing a gear-changing operation to a first target gear in dependence on the gear-changing request, and • modifying the characteristic map by assigning the first target gear to the detected speed variable and to the detected torque, • detecting at least o a first speed variable, representing the rotational speed of the pedal crank of the two-wheeled vehicle, and o a torque variable, representing torque applied to the pedal crank by the rider, and o the selected gear (n) of the automatic gear-shifting mechanism, and o a first speed variable, representing the rotational speed of the pedal crank of the two-wheeled vehicle, and o a torque variable, representing torque applied to the pedal crank by the rider, and o the selected gear (n) of the automatic gear-shifting mechanism, and • performing a gear-changing operation to an automatic gear in dependence on the speed variable, the torque and the selected gear (n) on the basis of a characteristic map, and • detecting a first manual gear-changing request of the rider, and • performing a gear-changing operation to a first target gear in dependence on the gear-changing request, and • modifying the characteristic map by assigning the first target gear to the detected speed variable and to the detected torque, characterized in that the method additionally includes the steps of • detecting a second manual gear-changing request after the first manual gear-changing instruction by the rider during a predetermined time period, and • modifying the characteristic map in dependence on a predetermined time period elapsing without a second manual gear-changing request being detected. • detecting a second manual gear-changing request after the first manual gear-changing instruction by the rider during a predetermined time period, and • modifying the characteristic map in dependence on a predetermined time period elapsing without a second manual gear-changing request being detected.
