Abstract (en)

[origin: WO2009003769A1] According to the invention, from the opening of the clutch (3), an additional braking torque is added to the braking torque of the drivetrain which is connected downstream of the clutch (3). The braking torque of the drivetrain which is connected downstream of the clutch (3) comprises for example the drag torques of the transmission (4), of an axle and/or of one or more brakes (6). The added additional braking torque corresponds to the braking torque of the internal combustion engine (2) on the wheel (5) of the drivetrain (1) at the moment or immediately before the moment in which the internal combustion engine (2) is decoupled, by the opening of the clutch (3), from the drivetrain which is connected downstream of the clutch (3). As a result of the addition of the additional braking torque to the drivetrain which is connected downstream of the clutch (3), the entire braking torque acting on the wheel (5) before the opening and also after the opening of the clutch (3) is kept constant. An increase in driving comfort of the vehicle is thereby obtained, as is an increase in safety since there is no abrupt change in the rolling resistance of the vehicle. The vehicle can therefore coast or stop in a smooth fashion.
