An audio control system for a vehicle includes a processor, a non-volatile memory module having stored therein instructions for controlling one or more vehicle audio components, a sensor operable to detect a change in vehicle configuration, and a control module operable to adjust a vehicle audio component based on the change in vehicle configuration according to instructions stored in the non-volatile memory module.

Vehicle audio control based on sensed physical changes in vehicle configuration

Presented are driver alert systems with control logic for powertrain energy tracking and reporting, methods for making/using such systems, and electric-drive vehicles with alert systems for providing driver cues to indicate real-time potential energy buildup in the powertrain. A method of operating a driver alert system for an electric-drive vehicle includes a vehicle controller receiving a selection of a powertrain operating mode. Responsive to the received selection, the vehicle controller determines a buildup of output torque generated via an electric traction motor for an impending vehicle maneuver associated with the selected powertrain operating mode. The controller accesses a memory-stored, torque-based lookup table to retrieve an output level calibrated to an in-vehicle sensory output device and corresponding to an output torque value for the determined torque buildup. The controller then commands the sensory output device to generate a driver-perceptible visible, audible, and/or tactile cue based on the retrieved output level.

A method for noise cancellation includes monitoring a system for a current operating point, monitoring the system for a predetermined disturbance, and in response to the predetermined disturbance, determining the disturbance to be in one of a transient or steady state response period. A set of data is selected corresponding to the current operating point of the system, the disturbance, and the response period from a database containing predetermined noise cancellation waveform data. A noise cancelling waveform is output to audio transducers based upon the selected set of data.
