A dual mass flywheel protection system includes an engine coupled to a transmission using a dual mass flywheel defining a drive train. A gear determiner identifies a present operational gear. A filtered engine speed is available. A torque reduction module applies the present operational gear and filtered engine speed producing signals limiting an engine torque to reduce engine torque variations. A first torque limitation option limits engine torque when the drivetrain is coupled, dependent on an engine rpm, which is related to an actual gear selected. A second torque limitation option determines an engine torque reduction during an emergency braking maneuver while an anti-lock brake (ABS) system is active. An engine shut-off module produces an output signal shutting off the engine upon initiation of one of multiple engine shut-off module outputs, and is active when an engine torque limitation due to a low engine rpm is not present.
