Embodiment Construction

[0086] figure 1 An exemplary flow of regulation 1 according to the present invention is shown in . In box 2, a setpoint value for regulation 1 is provided, which can be calculated and output as an initial value by the engine control system. In the case of an internal combustion engine, the desired value can be a desired torque, which is predetermined by the driver using the accelerator pedal. Correspondingly, the desired torque can be adjusted as a function of other parameters such as engine characteristic factors, gears engaged in the transmission, vehicle operating conditions, road surface conditions and the like. In block 3 , setpoint 2 is used for the control object, which may include the internal combustion engine as well as downstream components such as clutches, dual-mass flywheels or powertrain components such as auxiliary units and downstream transmissions. In the case of a dual-mass flywheel, the setpoint output to the internal combustion engine is in particular co...

Abstract

The drive chain has a drive unit controlled by a control unit with multiple cylinders and a drive shaft. A condition value of the dual mass flywheel is read in the controller. The condition value of a detection of misfire takes place over the entire speed range of the drive unit. An independent claim is included for a method for controlling a drive unit with multiple cylinders in a drive chain of a motor vehicle.

Description

technical field [0001] The invention relates to a powertrain system and a method for operating the powertrain system, in particular for a motor vehicle, the powertrain system having a drive unit controlled by means of a control device, the drive unit having A drive shaft and a dual mass flywheel operatively connected to and driven by the drive shaft. Background technique [0002] Arrangements in powertrain systems are already known in which the internal combustion engine is controlled by means of an engine management system. So-called flame misfires cannot be ruled out in this type of arrangement. A combustion misfire is an event in which the combustion of the air-fuel mixture in the cylinders of an internal combustion engine is completely or partially stopped. If no combustion or only partial combustion takes place, the cylinder performs no or less combustion work and no or less combustion torque is built up. [0003] The occurrence of combustion misfires can have differ...
