湿式离合器表面温度的确定方法及装置
摘要：
一种湿式离合器表面温度的确定方法及装置。所述方法包括：计算当前周期内因摩擦而产生的热量JC(k)；计算当前周期内流入所述湿式离合器的油液所吸收的热量JLC(k)；计算当前周期内所述湿式离合器自身的构件所散发的热量JCON(k)；根据所述第一差值，计算当前周期内所述湿式离合器表面温度的变化量；当k>1时，根据前一周期内所述湿式离合器表面的温度以及当前周期内所述湿式离合器表面温度的变化量，计算当前周期内所述湿式离合器表面的温度TC(k)；当k＝1时，根据检测到的所述湿式离合器的初始温度以及当前周期内所述湿式离合器表面温度的变化量，计算当前周期内所述湿式离合器表面的温度TC(k)。应用所述方法可以更加准确地确定所述湿式离合器表面的温度。

Provided are a method and a device for determining surface temperature of a wet clutch. The method comprises: calculating heat JC (k) generated by friction in a present period; calculating heat JLC(k) absorbed by oil liquid which flows into the wet clutch in the present period; calculating the heat JCON(k) dissipated by components of the wet clutch in the present period; according to a first difference, calculating variation of the surface temperature of the wet clutch; when k>1, according to temperature of the surface of the wet clutch in the previous period and the variation of the surface temperature of the wet clutch in the present period, calculating temperature TC(k) of the surface of the wet clutch in the present period; when k=1, according to the detected initial temperature of the wet clutch and the variation of the surface temperature of the wet clutch in the present period, calculating temperature TC(k) of the surface of the wet clutch in the present period. Using the method can accurately determine the temperature of the surface of the wet clutch.
