Abstract
A method for operating an internal combustion engine of a vehicle traveling on the road, the method comprising of damping engine vibration with a damper coupled to the engine, and when said damping is reduced, preventing engine speed from falling below a threshold value, at least under selected operating conditions, to reduce degradation of the engine that would otherwise occur.
