System Description: Overview

WARNING: This page is about a different car, the 2011 Honda Pilot, 2010 Honda Pilot, and 2009 Honda Pilot. However, it is still accessible from the selected car via links, so may be relevant.

The active control engine mount (ACM) system reduces the amount of engine vibration that creates engine noise which is transmitted to the passenger's compartment.

The ACM system consists of the engine mount actuators, the engine mount control unit and the powertrain control module (PCM).

The PCM sends the crankshaft position (CKP) sensor information and camshaft position (CMP) sensor information to the engine mount control unit. The engine mount control unit uses this information to predict the amount of vibration created by the engine.

The ACM system then uses the engine mount actuators to generate a canceling vibration that operates like the active noise control (ANC) and reduces the amount of noise and vibration in the passenger's compartment.
