Operation notification sound emission device for vehicle
First Claim
1. An operation notification sound emission device equipped to a vehicle configured to travel with a traveling electric motor as a power source, the traveling electric motor being configured to be controlled with a first control device, the operation notification sound emission device being configured to emit an operation notification sound to notify the vehicle being in an operation state, the operation notification sound emission device comprising:
- a synthetic circuit configured toreceive a driving signal from a second control device for an other electric motor, wherein the second control device is distinct from the first control device, wherein the other electric motor is distinct from the traveling electric motor, andsynthesize, according to the driving signal, the operation notification sound imitative of a motor sound emitted from the traveling electric motor; and
an emission unit configured to emit the operation notification sound synthesized by the synthetic circuit, wherein;
the driving signal controls the other electric motor, andthe other electric motor is a three-phase electric motor, andthe synthetic circuit is further configured to;
receive a three-phase driving signal from the second control device andsynthesize the operation notification sound according to the three-phase driving signal.

Abstract
A vehicle travels with a traveling electric motor controlled with a first control device. A synthetic circuit receives a driving signal from a second control device, which is for controlling another electric motor distinct from the traveling electric motor. The synthetic circuit synthesizes, according to the driving signal, the operation notification sound imitative of a motor sound emitted from the traveling electric motor. An emission unit emits an operation notification sound synthesized by the synthetic circuit to notify the vehicle being in an operation state.
