Abstract

A method of controlling sounds associated with a vehicle is provided. The method includes: performing on a processor, monitoring engine torque; and selectively controlling the generation of one or more tones associated with the vehicle based on the engine torque.

Description

technical field [0001] Exemplary embodiments of the present invention relate to systems and methods for achieving auditory smoothing in a vehicle. Background technique [0002] A vehicle control system monitors the power demand of the vehicle and selectively controls one or more powertrain components, thereby improving fuel economy. For example, during low power consumption activities, the vehicle control system may switch the powertrain from operating the engine to operating the electric motor. Likewise, the vehicle control system may switch the powertrain from running the electric motor to running the engine during high power consuming activities. Such transitions can cause sudden changes in the sound emitted by the vehicle. Such unexpected sound abrupt changes are undesirable for the vehicle driver. Accordingly, there is a need to provide systems and methods for improving the overall sound spectrum of a vehicle. Contents of the invention [0003] In one exemplary em...
