The present invention relates to a driving control device for an electric vehicle. The driving control device for an electric vehicle comprises: a driving motor; a main control part which generates and outputs a control signal to control the driving of the electric vehicle and controls charging and discharging of a battery; a sensor part which senses input voltage and input current applied from the battery to the driving motor, and a speed of the electric vehicle to output a sensing value; a sound source generation part which generates or sets a sound source; and a sound output part which outputs sound corresponding to the sound source as the driving sound of the electric vehicle. The main control part comprises a motor control part, a sound control part and a communication part. The main control part includes a motor control part which transmits a response signal with respect to the control signal to the main control part, a sound source control part which determines the driving of the driving motor when a motor driving control signal for driving the driving motor is applied to the motor control part, controls the sound source generation part to output the sound through the sound output part, and performs a control operation to stop the sound output of the sound output part when the speed of the vehicle reaches a predetermined speed, and a communication part which communicates with the motor control part or the sound source control part through a controller area network (CAN) communication. According to the present invention, the driving control device for an electric vehicle secures safety in controlling the driving motor, increases efficiency, and thus, improves fuel efficiency. In addition, sound similar to the driving sound of the engine is outputted in accordance with the controlled state of the driving motor while the vehicle is driven to allow a driver and a pedestrian to recognize the electric vehicle, thereby preventing an accident.

    본 발명은 전기자동차의 구동제어장치에 관한 것으로서, 구동모터와; 전기자동차의 주행을 제어하기 위한 제어신호를 생성 및 출력하고, 배터리의 충전 및 방전을 제어하는 메인제어부와; 상기 배터리로부터 상기 구동모터에 인가되는 입력전압과 입력전류 및 전기자동차의 속도를 감지하여 센싱값을 출력하는 센서부와; 음원을 생성 또는 설정하는 음원생성부와; 상기 음원에 대응하는 소리를 전기자동차의 구동음으로 출력하는 음향출력부;를 구비하고, 상기 메인제어부는 상기 제어신호에 대하여 응답신호를 상기 메인제어부로 전송하는 모터제어부와, 상기 모터제어부로 상기 구동모터를 구동시키기 위한 모터구동제어신호가 인가되면 상기 구동모터가 구동하는 것으로 판단하여 상기 음향출력부를 통해 음향이 출력되도록 상기 음원생성부를 제어하고 차량의 속도가 일정 속도에 도달하면 상기 음향출력부의 음향출력을 중지시키도록 제어하는 음원제어부와; 캔 통신을 통해 상기 모터제어부 내지 음원제어부와의 통신을 수행하는 통신부를 포함한다. 본 발명에 따른 전기자동차의 구동제어장치는 구동모터의 제어 안정성 확보 및 효율 증대, 그로 인한 연비 향상을 도모하면서, 차량 주행 중 구동모터의 제어 상태에 따라 엔진 구동음과 유사한 음향을 출력함으로써 운전자 및 보행자가 인식할 수 있게 하여 사고를 미연에 예방할 수 있는 장점을 가진다.
