Abstract
A vehicle sound simulation system and sound simulation methodologies are provided. The vehicle sound simulation system includes a sound playback device utilized to produce sound signals. As a vehicle is operated, the vehicle sound simulation system approximates an engine state and generates sounds corresponding to the engine state. The vehicle sound simulation system generates sounds in accordance with a vehicle sound generation routine that utilizes a number of inputted parameters to vary the sounds generated through the sound playback device.
Claims18
A vehicle sound simulation system comprising:
- a vehicle input interface component for obtaining vehicle operation information generated by a vehicle in operation, the vehicle operation information including a measure of vehicle velocity information and vehicle throttle position information;
- a processing component, executed on a processing component, the processing component for:
- determining whether a vehicle velocity state corresponds to a stationary state based on a determination whether the vehicle operation information exceeds a velocity threshold;
- if so, selecting sound signals based on the vehicle throttle position information;
- determining whether a vehicle velocity state corresponds to a non-stationary state;
- and
- if so, determining an applicable category of vehicle velocity state, wherein the applicable category of vehicle velocity state corresponds to one or more predefined states;
- selecting a sound signal based on a category of vehicle velocity state;
- and
- an external interface component for causing the generation of selected sound signals.
