The invention provides an extended-range electric vehicle cooling fan control method. The extended-range electric vehicle cooling fan control method comprises the steps of acquiring a first PWM speedregulation value, a second PWM speed regulation value and a third PWM speed regulation value, capable of meeting heat dissipation requirements of an electric driving system, an air conditioning systemand an engine system, of a fan; determining a compensation value according to the first PWM speed regulation value, the second PWM speed regulation value and the third PWM speed regulation value; obtaining the maximum PWM value in the first PWM speed regulation value, the second PWM speed regulation value and the third PWM speed regulation value; and determining an operation PWM value of the fanaccording to the maximum PWM value and the compensation value. By adopting the matching control of the PWM value and the compensation value, the fan can meet the requirements of three different systems for the fan under different working conditions at the same time, an extra fan controller does not need to be additionally arranged, control is facilitated, and cost is reduced.

    本申请提供了一种增程式电动车冷却风扇控制方法,其包括:分别获取风扇能够满足电驱动系统、空调系统和发动机系统散热需求的第一PWM调速值、第二PWM调速值和第三PWM调速值;根据第一PWM调速值、第二PWM调速值和第三PWM调速值确定补偿值;获取第一PWM调速值、第二PWM调速值和第三PWM调速值中的最大PWM值;根据最大PWM值和补偿值确定风扇的运行PWM值。本申请通过采用PWM值与补偿值的匹配控制,实现了使风扇能够同时兼顾三种不同系统在不同的工况下对风扇的需求,无需增加额外的风扇控制器,方便了控制,降低了成本。
