The present disclosure provides "predictive inductor cooling". An automotive propulsion system has a transmission including an output shaft; a variable voltage converter, the variable voltage converter including an inductor disposed within a housing of the transmission such that a transmission fluid within the housing contacts the inductor to cool the inductor; and a controller that maintains a magnitude of current through the inductor to be less than a limit value defined by a speed associated with the output shaft and a switching frequency of the variable voltage converter. 本公开提供了"预测性电感器冷却"。一种汽车推进系统，具有：变速器，所述变速器包括输出轴；可变电压转换器，所述可变电压转换器包括电感器，所述电感器设置在所述变速器的壳体内，使得所述壳体内的变速器流体接触所述电感器以冷却所述电感器；以及控制器，所述控制器将通过所述电感器的电流的量值维持为小于由与所述输出轴相关联的速度和所述可变电压转换器的切换频率限定的极限值。
