Active engine mountsActive engine mounts reduce undesirable vibration excitation from the engine by generating compensating counter-oscillations. The hydraulically damped engine mounts utilize an electromagnetic oscillating coil actuator for this purpose. To ensure that it always supplies the proper control signal – even during quick changes in vehicle state – an algorithm constantly evaluates the data of accelerometers mounted in the engine compartment and adapts the control signal to accordingly.
Active engine mounts help to enhance ride comfort in models with cylinder deactivation and in diesel models. They are also used in plug-in hybrid vehicles to ensure a uniform driving experience while switching between operating modes.
