Abstract

The invention relates to a system for equipping an electric vehicle (1) comprising: - at least one sound generation module (2) configured to generate sound vibrations having at least one frequency and one amplitude; - a control unit (37) for controlling said sound generation module (2), said control unit (37) being configured to, at least in one sound generation mode: - receive a variable (38) representing a rotational speed Vmot of an electric motor (9) of the electric vehicle (1) and a variable (39) representing an acceleration setpoint Sacc of the electric vehicle (1);and - control the sound generation module (2) as a function of the variable (38) representing the speed Vmot and the variable (39) representing the acceleration setpoint Sacc so as to vary the frequency of the sound vibrations as a function of the variable (38) representing the speed Vmot and the amplitude of the sound vibrations as a function of the variable (39) representing the acceleration setpoint Sacc.
