Technology Highlights

• An algorithm on the computer pairs each EMV operating-element output signal with an associated ICE sound at the corresponding performance level and generates a composite digital signal that dynamically simulates the target combustion engine in real time.
• A set of sensors — including a speedometer, accelerometer, wattmeter, first tachometer (crankshaft RPM), and second tachometer (transmission RPM) — measures real-time performance parameters of the EMV’s operating elements and generates output signals.
• A plurality of data sets are positioned on the computer, each comprising digital audio signals corresponding to sounds produced by respective mechanical elements of a reference ICEV (e.g., engine, transmission, exhaust) at respective performance levels.
• An electronics module configured to be mountable to any electric motor vehicle, integrating the sensor array, computer (with algorithm and datasets), and DAC in a single unit — deployable without vehicle OEM factory modification.
• A server amalgamates composite digital signals from multiple EMV electronics modules, adjusts each signal based on vehicle GPS location and speed (including Doppler shifting), and selectively communicates speaker-specific signals to venue speakers for position-accurate ICE sound broadcast.
• Distinctive Claim Limitations Key distinctive limitations: (1) sensor-level measurement of EMV operating elements; (2) algorithm pairing each output signal with ICE sounds at corresponding performance levels; (3) DAC-based composite digital-to-analog conversion for external speaker broadcast; and (4) serverbased multi-vehicle signal amalgamation with GPS Doppler correction for racing venue broadcast. These limitations distinguish the claims from fixed-tone AVAS compliance devices.

• Racetrack Wi-Fi AP Grid Three to ten Wi-Fi access points blanket the track and capture real-time RPM telemetry directly from each kart’s dashboard controller as it races.
• Spatial Audio Zones As karts move around the track, sound automatically shifts to the nearest speaker — creating a realistic, position-accurate racing sound field.
• RPM Data Interpreter Laptop RPM telemetry is transmitted over Wi-Fi to a dedicated laptop, which converts it into dynamic, high-performance engine audio in under 50 milliseconds.
