Abstract
The invention relates to a method for starting an internal combustion engine of a hybrid vehicle, where an electric motor of the hybrid vehicle is accelerated to a predetermined engine speed and a hybrid disconnect clutch, which is arranged between the internal combustion engine and the electric motor, is moved in the closing direction depending on the set-point clutch torque. In a method which safeguards a high reproducibility of the restart operation, the set-point clutch torque for restarting the internal combustion engine is determined depending on an engine switch-off position of the internal combustion engine in a first phase in which the internal combustion engine is not running.

A method for starting an internal combustion engine in a hybrid vehicle, comprising accelerating an electric motor of the hybrid vehicle to a predetermined motor speed and moving a hybrid disconnect clutch arranged between the internal combustion engine and the electric motor depending on a set-point clutch torque to be transmitted in a closing direction, and in a first phase in which the internal combustion engine is switched off, determining the set-point clutch torque for restarting the internal combustion engine depending on a motor switch-off position of the internal combustion engine.
