Abstract
An audio system of a vehicle includes a mode module that sets a mode signal to a first mode when a vehicle speed is greater than a predetermined speed and a longitudinal acceleration of the vehicle is less than a predetermined acceleration. The predetermined acceleration is less than zero and the predetermined speed is greater than zero. A sound control module, when the mode signal is in the first mode, selectively sets audio characteristics for a deceleration event of the vehicle based on randomization parameters. An audio driver module, based on the audio characteristics, applies power to speakers to output sound within a passenger cabin of the vehicle.
Claims20
An audio system of a vehicle, comprising:
- a mode module that sets a mode signal to a first mode when a vehicle speed is greater than a predetermined speed and a longitudinal acceleration of the vehicle is less than a predetermined acceleration,
- wherein the predetermined acceleration is less than zero and the predetermined speed is greater than zero,
- a sound control module that, when the mode signal is in the first mode, selectively sets audio characteristics for a deceleration event of the vehicle based on randomization parameters;
- and
- an audio driver module that, based on the audio characteristics, applies power to speakers to output sound within a passenger cabin of the vehicle.
A vehicle audio system, comprising:
- at least one memory comprising computer executable instructions;
- at least one processor configured to read and execute the computer executable instructions, the computer executable instructions causing the at least one processor to:
- set a mode signal to a first mode when a vehicle speed is greater than a predetermined speed and a longitudinal acceleration of the vehicle is less than a predetermined acceleration,
- wherein the predetermined acceleration is less than zero and the predetermined speed is greater than zero;
- when the mode signal is in the first mode, selectively set audio characteristics for a deceleration event of the vehicle based on randomization parameters;
- and,
- based on the audio characteristics, apply power to speakers to output sound within a passenger cabin of the vehicle.
A non-transitory computer readable medium comprising computer executable instructions, the computer executable instructions configured to cause a processor to perform a method, the method comprising:
- setting a mode signal to a first mode when a vehicle speed is greater than a predetermined speed and a longitudinal acceleration of the vehicle is less than a predetermined acceleration,
- wherein the predetermined acceleration is less than zero and the predetermined speed is greater than zero;
- when the mode signal is in the first mode, selectively setting audio characteristics for a deceleration event of the vehicle based on randomization parameters;
- and,
- based on the audio characteristics, applying power to speakers to output sound within a passenger cabin of the vehicle.
