  • Method for actively dampening a start-up resonance of a torsional damper when starting an internal combustion engine
    Patent number: 11519377
    Abstract: A method actively dampens a start-up resonance of a torsional damper when starting an internal combustion engine. The torsional damper (4) is fixed between an internal combustion engine (1) and a secondary side (5) of a torsional elasticity, and the internal combustion engine (1) is started using a starter generator (3) arranged on a side of the internal combustion engine (1) counter to the torsional elasticity. A counter excitation is applied to a torque generated by the starter generator (3) when the internal combustion engine (1) is started, which counter excitation is modulated on the basis of a parameter of the internal combustion engine (1) which changes when the internal combustion engine (1) is being started.

  • Drive train
    Patent number: 7761224
    Abstract: A drive train, for a motor vehicle that has a drive unit controlled by a control device, a driveshaft and an element, which is operatively connected to the drive shaft and is driven by the same. At least one state value of the driven element is read into the control device, and a balancing of the cylinder of the drive unit is carried out utilizing the at least one state value.
