Motor vehicle's hybrid drive train controlling method, involves providing hybrid drive train with clutch, and digitally closing and/or opening clutch during attaining synchronous speed range between clutch input and clutch output

摘要

The method involves providing a hybrid drive train (1) with a clutch (5) that includes a clutch input (6) and a clutch output (7). Electrical power is generated by a generator (9) and used for driving a motor vehicle (2) using an electric machine (11). The clutch is closed in a clutched operating condition and a power flow is transmitted from an internal combustion engine (8) to a gear (10). The clutch is digitally closed and/or opened during attaining synchronous speed range between the clutch input and the clutch output.
