Abstract:
A method of controlling an automated multi-step change-speed transmission of a vehicle having an electronic control unit connected to sensors for detecting operating parameters and to gear and/or clutch control elements for carrying out shift operations. The control comprises a data memory such that the multi-step change-speed transmission can be operated automatically to initiate gearshifts in an automatic mode, manually initiated by a driver in a manual mode to provide gearshifts, and manually actuated in a learning mode in which gearshifts and operating parameters can be recorded automatically. When necessary to assist technicians in the application of the transmission, a configuration-learning mode that can be activated in which, during a test drive with manual gearshift initiation, operating parameters are automatically detected in an event-dependent manner, processed to produce control data for the transmission, and the control data stored in the data memory for the future control of the transmission.
