Abstract

The acoustic signaling system for electric, hybrid vehicles or the like, which can be installed on an electric vehicle or the like, includes: an amplifier device of a piloting signal; an electroacoustic transducer device operatively connected to the amplifier device; a supervision unit operatively connected to a control device installed on the electric vehicle; a digital audio processor operatively connected to the supervision unit and to the amplifier device; wherein the supervision unit has elements for sending a command signal to the digital audio processor according to a check signal sent by the control device; wherein the digital audio processor has selection elements suitable for selecting one between at least two different audio files, according to the command signal received; and wherein the digital audio processor has processing elements suitable for producing the piloting signal starting from the audio file selected.

Dependent claims

Acoustic signaling system (S) for an electric or hybrid vehicle, which can be installed on the electric, comprising at least an amplifier device (A) of a piloting signal (SP) and at least an electroacoustic transducer device (L) operatively connected to said amplifier device (A), comprising:

at least a supervision unit (MCU) operatively connected to at least a control device (D) installed on said electric vehicle (V);
at least a digital audio processor (DSP) operatively connected to said supervision unit (MCU) and to said amplifier device (A);
wherein said supervision unit (MCU) has means for sending at least a command signal (SCOM) to said digital audio processor (DSP) according to at least a check signal (SCHK) sent by said control device (D);
wherein said digital audio processor (DSP) has selection means suitable for selecting one between at least two different audio files (F1, F2), according to said command signal (SCOM) received;
and
wherein said digital audio processor (DSP) has processing means suitable for producing said piloting signal (SP) starting from said audio file (F1, F2) selected, and
wherein said at least an audio file (F1, F2) is selected at least between:
at least a first audio file (F1) relative to an alarm audio signal suitable for signaling an attempted theft of said electric vehicle (V) and/or an attempted break-in inside said electric vehicle (V), when said electric vehicle (V) is stopped;
and
at least a second audio file (F2) relative to a proximity warning audio signal suitable for signaling an approach of said electric vehicle (V), when said electric vehicle (V) is running.
