Abstract
A vehicle having a chassis with a body and a drive train disposed on the chassis is disclosed. The drive train includes a metal housing having a void and a damping element disposed within the void. Also disclosed is a controller for damping vehicle noise that includes a processing circuit for executing instructions for: receiving a signal representative of a sensed vibration at a metal housing of the vehicle; in response to the sensed vibration, generating a control signal to activate a camping element disposed at a void within the metal housing; and causing the damping element to change in such a manner as to change the damping characteristics at the void of the metal housing.
Claims16
A vehicle, comprising:
- a chassis;
- a body disposed on the chassis;
- and
- a drive train disposed on the chassis, the drive train comprising a metal housing having a void and a damping element disposed within the void.
An engine block for a vehicle, comprising:
- a housing having a void;
- and
- a damping element disposed within the void.
A method of damping vehicle noise, comprising:
- sensing a vibration at an engine of the vehicle;
- in response to the sensed vibration, generating a control signal to activate a damping element disposed at a void within the engine;
- and
- in response to the control signal, causing the damping element to change in such a manner as to change the damping characteristics at the void of the engine.
A controller for damping vehicle noise, comprising:
- a processing circuit;
- and
- a storage medium, readable by the processing circuit, storing instructions for execution by the processing circuit for:
- receiving a signal representative of a sensed vibration at a metal housing of the vehicle;
- in response to the sensed vibration, generating a control signal to activate a damping element disposed at a void within the metal housing;
- and
- causing the damping element to change in such a manner as to change the damping characteristics at the void of the metal housing.
