Disclosed is an active sound generation apparatus using a motor, the apparatus including a target sound generating signal generator configured to select the target sound and to generate a current command signal for driving the motor to generate the target sound, a current sensor configured to sense phase current of the motor, a motor controller configured to generate a voltage command for drivingthe motor to generate the target sound and to control driving of the motor based on a current command signal generated by the target sound generating signal generator, the phase current of the motor sensed by the current sensor, and a counter electromotive force compensation value of the motor, and a radiated noise generator configured to generate the target sound using vibration generated from the motor driven by the motor controller.

    本发明公开一种使用电动机的主动发声装置,用于通过控制安装在车辆中的三相电动机来主动产生预期的目标声音,该装置包括:目标声音生成信号发生器,被配置成选择目标声音并产生用于驱动电动机以产生目标声音的电流指令信号;电流传感器,被配置成感测电动机的相电流;电动机控制器,被配置成基于由目标声音生成信号发生器产生的电流指令信号、由电流传感器感测的电动机的相电流、以及电动机的反电动势补偿值,产生用于驱动电动机的电压指令,并控制电动机的驱动,从而产生目标声音;以及辐射噪声发生器,被配置成利用由电动机控制器驱动的电动机产生的振动,产生目标声音。
