Reducing noise, vibration and roughness in a Skip Fire (cylinder deactivation / activation) - Motorsteuerungssytem

There are different methods and arrangements for reducing NVH in a skipfire engine control system described. In one aspect, an ignition portion for skipfire-like operating the motor is used. is applied to a release device powertrain - / - a compensating torque by the energy storage is determined. The balancing torque is adapted to cancel a torque variation generated by the skipfire firing order at least partially. There are further various methods powertrain controllers, devices and computer software associated with the above operations in the context described.
