PURPOSE: A dashboard system of an electrical scooter is provided to inform a driver and a pedestrian of a running state by outputting a running state sound to the outside, and to prevent an accident in advance. CONSTITUTION: A dashboard system (180) of an electrical scooter comprises a control unit (181), an internal interface unit (182), a memory unit (183), an audio data processing unit (184), an external interface unit (186), a graphic processing unit (187), a dashboard screen (188), and a dashboard control unit (189). The control unit produces an input signal according to a menu which is selected through button keys or a screen by a driver. The internal interface part receives the information which is generated a motor control unit and a battery management system by using a controller area network (CAN) communication. The memory unit stores various digital audio data which is applicable to a running state sound. The audio data processing unit changes digital audio data into analog audio data to be output through a speaker (185). The external interface unit receives audio data from external devices. The graphic processing unit processes graphics so that a variety of information is indicated on a dashboard screen. The dashboard control unit controls the running state sound to be output based on the information which is received by the internal interface unit. The dashboard control unit controls the audio data, which are delivered through the external interface unit from the external devices, to be output as the running state sound.
