VEHICLE AUDIO SYSTEM FOR PRODUCING SYNTHETIC ENGINE SOUND
First Claim
1. An electrically powered passenger vehicle comprising:
- an electric drive motor operatively coupled to one or more of the vehicle'"'"'s wheels for rotating the vehicle'"'"'s wheels to propel the vehicle;
a battery pack for powering the electric drive motor;
a controller for controlling the speed of the vehicle;
a sensor for monitoring a performance parameter of the vehicle;
a data storage unit including one of pre-recorded engine sounds, pre-recorded exhaust sounds, or one or more algorithms for reproducing engine sounds and exhaust sounds;
a processor for accessing the data storage unit and retrieving one of pre-recorded engine sounds, pre-recorded exhaust sounds, or one or more algorithms for reproducing engine sounds and exhaust sounds;
an amplifier operably connected to the processor for amplifying one of an engine sound or exhaust sound;
at least one speaker operably connected the amplifier for projecting one of engine sounds or exhaust sounds outside the vehicle; and
wherein the processor receives an input generated by the sensor and varies a sound parameter of one of engine sounds or exhaust sounds projected by the speaker based on a performance parameter of the vehicle.
