Abstract: A method for operating a hybrid vehicle that includes a prime mover (1) with an internal combustion engine (2), an electric machine (3), a transmission (4) connected between the prime mover (1) and a driven end (5), and multiple shift elements, including a separating clutch (7) connected between the internal combustion engine (2) and the electric machine (3), and a starting component (8), is provided. After release of a brake pedal (12) or together with the release of the brake pedal (12) for a driving start or an crawling start, an engagement speed threshold (22) for the starting component (8) is established below an idling speed of the prime mover (1) and a previously disengaged starting component (8) is engaged. A control unit (9, 10, 11) for carrying out such a method is also provided.

Abstract: A method is provided for controlling regenerative braking for a vehicle having a propulsion system, a motor, a transmission, and a clutch selectively coupling the motor to the transmission. The method includes estimating a future time at which the clutch disengages from the transmission. A rotational speed at which the clutch disengages from the transmission is calculated based on an idle speed of the propulsion system. A difference between a speed of the motor and the clutch disengage speed is monitored. A ramp down of regenerative torque on the motor is initiated when the difference is below a predetermined value and before the future clutch disengage time elapses.
