Noise control of thermal components in a hybrid electric vehicle

摘要

Noise control for a vehicle is implemented by identifying sources of noise that are indicative of vehicle noise producing components. The sources of noise include a thermal management device of a hybrid-electric component of the vehicle and non-hybrid-electric components of the vehicle. The noise control is further implemented by determining a decibel value of the noise produced by each of the vehicle noise producing components, selecting the decibel value of one of the vehicle noise producing components having a highest decibel value as a mask limit, and determining an operational limit for the thermal management device. The operational limit includes a lowest threshold operating value which, when implemented, maintains a threshold level operating efficiency of the hybrid-electric component. If a decibel value of the noise produced by the thermal management device exceeds the mask limit, the noise control includes reducing a level of operation of the thermal management device to coincide with the decibel value of the operational limit.

1. A method for implementing noise control for a vehicle, the method comprising:
identifying sources of noise in the vehicle, via a computer processor, the sources of noise indicative of vehicle noise producing components and include a thermal management device of a hybrid-electric component of the vehicle and non-hybrid-electric components of the vehicle; determining a decibel value of the noise produced by each of the sources of noise; selecting, via the computer processor, the decibel value of one of the vehicle noise producing components having a highest decibel value as a mask limit; determining an operational limit for the thermal management device, the operational limit including a lowest threshold operating value which, when implemented, maintains a threshold level operating efficiency of the hybrid-electric component; determining a decibel value associated with the operational limit; if a decibel value of the noise produced by the thermal management device exceeds the mask limit, reducing a level of operation of the thermal management device to coincide with the decibel value of the operational limit; and if the decibel value of the noise produced by the thermal management device is lower than or meets the mask limit, maintaining a current level of operation of the thermal management device.
