The present disclosure provides a system and method for adaptive pulse width modulation. Methods and systems are provided for adaptive pulse width modulation control of an electrically powered powertrain of a vehicle. In one example, a method may include perturbing a switching frequency for pulse width modulated control of an electromotive powertrain; and controlling the motorized powertrain with a switching frequency of the disturbance in response to the sound measured in the cabin indicating an improvement in noise after the disturbance. In this manner, acoustic emissions from the motorized powertrain may be reduced.

    本公开提供了“用于自适应脉冲宽度调制的系统和方法”。提供了用于车辆的电动化动力传动系统的自适应脉冲宽度调制控制的方法和系统。在一个示例中,一种方法可以包括:扰动用于电动化动力传动系统的经脉冲宽度调制的控制的开关频率;以及响应于在车厢中测量的声音指示在扰动之后的噪声改进而利用扰动的开关频率控制电动化动力传动系统。通过这种方式,可以减少来自电动化动力传动系统的声学发射。
