 Dual-mass flywheel

In order to reduce fuel consumption and CO2 emissions, high-charged engines are used, the number of cylinders is reduced and the drivable speeds are lowered. However, with these measures the torsional vibrations of the crankshaft are increased as a result of the acceleration during the work cycle

 Monitoring functions

High-voltage interlock loop The SME control unit evaluates the signal of the high-voltage interlock loop and checks whether there is an open circuit with this circuit. In the event of an open circuit, the battery management electronics control unit can cause the high-voltage system to perform a qu
