Title:
DEVICE FOR GENERATING AND TUNING ENGINE SOUND/EXHAUST SOUND OF ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2017/099468
Kind Code:
A1
Abstract:
The present invention is to provide a device for generating and tuning an engine sound/exhaust sound of an electric motor, which can be simplified in terms of configuration by detecting a PWM scheme which is a control signal of an electric motor and generating a sound in conjunction with a virtual engine sound/exhaust sound. The device comprises: a controller for outputting a driving signal to a steering processing unit and a driving processing unit on the basis of a control signal inputted through an external interface; and a sound generation unit for detecting a driving control signal of a PWM scheme transmitted from the external interface to predict motion information of the electric motor and generating a sound corresponding to a motion of the electric motor in conjunction with a virtual engine sound and an exhaust sound which are pre-stored in advance.
