Sound and performance emulator for electric vehicles

Emulator for an electric propulsion vehicle comprising a processor configured to:

• determine an acceleration signal relating to a position of an accelerator of the electric propulsion vehicle;
• determine a value relating to engine revolutions of an electric motor of the electric propulsion vehicle based on a vehicle speed signal of the electric propulsion vehicle and/or based on an engine revolution signal relating to the engine revolutions of the electric motor of the electric propulsion vehicle;
• determine a simulated gear inserted value of a simulated endothermic combustion vehicle;
• calculate a value of simulated engine revolutions at a current time depending on at least one of the acceleration signal, the value relating to engine revolutions of the electric motor and the simulated gear inserted value;
• and
• calculate at least one of:
• a simulated torque value as a function of the simulated engine revolutions value and of the acceleration signal;
• and
• an accelerator control signal as a function of the simulated torque value;
• and
• control the electric motor of the electric propulsion vehicle based on the simulated torque value or the accelerator control signal,
• wherein the emulator further comprises a memory operatively connected to the processor and comprising a motor brake/inertia parameter map of the simulated vehicle, wherein an engine/brake torque value is associated with a respective variation of the value of simulated engine revolutions, and
• wherein the processor is further configured to:
• calculate a variation of the simulated engine revolutions and obtain an engine brake/inertia torque value, and
• correct the simulated torque value at a current time based on the engine brake/inertia torque value and the simulated torque value at the preceding time to obtain regenerative braking when the simulated torque value is less than zero.
