Abstract
An exhaust sound enhancement (ESE) system for a vehicle without an internal combustion engine includes one or more speakers, an amplifier configured to generate and play sounds on the one or more speakers, and a tuned exhaust assembly with a housing configured to resonate, amplify and inter-modulate the sounds from the one or more speakers to mimic exhaust sounds that would be produced by a predetermined internal combustion engine.
Claims17
An exhaust sound enhancement (ESE) system for a vehicle without an internal combustion engine, comprising:
- one or more speakers;
- an amplifier configured to generate and play sounds on the one or more speakers;
- and
- a tuned exhaust assembly with a housing configured to resonate, amplify and inter-modulate the sounds from the one or more speakers to mimic exhaust sounds that would be produced by a predetermined internal combustion engine.
A vehicle without an internal combustion engine, comprising:
- a motor configured to generate and transfer torque to one or more axles;
- a sensor system configured to monitor and sense an operational condition of the vehicle;
- an exhaust sound enhancement (ESE) system including an amplifier, one or more speakers, and a tuned exhaust assembly;
- and
- a controller in signal communication with the sensor system and the ESE system, and configured to receive one or more signals from the sensor system indicative of the sensed operational condition of the vehicle,
- wherein the controller is configured to, based on the one or more received signals, generate and play sounds on the one or more speakers, and
- wherein the tuned exhaust assembly includes a housing configured to resonate, amplify, and inter-modulate the sounds from the one or more speakers to mimic exhaust sounds that would be produced by a predetermined internal combustion engine operating at the sensed operational condition of the vehicle.
