A method to detect whether combustion is taking place in an internal combustion engine of a hybrid vehicle during operation of the hybrid vehicle, whereby a decoupler is provided between the internal combustion engine and an electric machine that serves to power the hybrid vehicle, comprising opening the decoupler between the internal combustion engine and the electric machine, receiving a speed signal when the decoupler is open, said signal indicating a rotational speed of the internal combustion engine when the decoupler is open, and determining, on the basis of the speed signal when the decoupler is open, whether combustion is taking place in the internal combustion engine. The present invention also relates to a control device to carry out the method according to the invention.

Method and control device for detecting, during the operation of a hybrid vehicle, whether combustion is taking place in an internal combustion engine of the hybrid vehicle

The invention relates to a method for controlling a drive system with at least two drive units (), each of which is paired with at least one control unit (), wherein &#x2014;a total target torque () is calculated by means of a master control unit (), &#x2014;the total target torque () is divided into respective individual target torques () for each of the drive units () by the master control unit (), and &#x2014;the drive units () are actuated by the paired control units () on the basis of the corresponding individual target torques (). The invention is characterized in that the threshold torques () corresponding to the drive units () are ascertained and taken into consideration by the master control unit () when dividing the total target torque ().

The present invention relates to a method for a vehicle () having an electric machine (). The electric machine () is coupled to at least one wheel () of the vehicle (). The vehicle () can optionally be operated in at least a first operating mode () and a second operating mode (). In the first operating mode (), the electric machine () applies a torque to the wheel (), and in the second operating mode () the electric machine () does not apply any torque to the wheel (). In the method, a request for switching over between the first and the second operating modes () is detected and the vehicle () is operated in a transition operating mode () if the request to switch over from the first operating mode () into the second operating mode () is detected. In the transmission operating mode (), a torque is applied to the at least one wheel () counter to a rolling direction of the vehicle () for at least a predetermined time.
