Abstract:
1. A vibration-isolating and sound-isolating system for a vehicle, having an engine and a vehicle body frame, said vehicle having a vehicle compartment, said system comprising: a vibration-isolating device supporting said engine on said vehicle body frame; a first controller controlling said vibration-isolating device so that vibration of the engine is inhibited from being transmitted to the vehicle body frame; a speaker disposed within said vehicle compartment; a second controller controlling noise within said vehicle compartment by controlling sound from said speaker so that the noise is reduced; a first sensor detecting a crank pulse signal from the engine; a second sensor detecting rotational speed of the engine; and a microphone disposed within said vehicle compartment, wherein said vibration-isolating device is controlled by said first controller based on the crank pulse signal from the engine as detected by the first sensor and sound from said speaker is controlled based on the rotational speed of the engine as detected by the second sensor and on the noise sensed by said microphone.
