The invention discloses a protection method of a vehicle power device, a motor control device and a computer storage medium. The method comprises the following steps: acquiring temperature values detected by two or more thermosensitive elements at regular time; comparing the temperature values of different thermosensitive elements at the same moment, and determining the maximum temperature value; and comparing the maximum temperature value with a first temperature threshold value, and if the maximum temperature value exceeds the first temperature threshold value, reducing the power of the power device. The problem that the cooling liquid flow is abnormal in the using process of a vehicle is solved.

    本发明公开了一种车用功率器件的保护方法、电机控制装置和计算机存储介质,该方法包括以下步骤:定时获取两个以上热敏元件检测到的温度值;比较在同一时刻不同的热敏元件的温度值,并确定最大温度值;比较最大温度值与第一温度阈值,若最大温度值超出所述第一温度阈值,则降低述功率器件的功率。解决了车辆在使用过程中存在冷却液流量异常问题。
