Method of controlling transmission for reducing clutch abrasion and automatic transmission controlled by method
Disclosed are a method of controlling a transmission for reducing clutch abrasion and an automatic transmission controlled by the method. The method is applied to a hybrid vehicle, and controls an automatic transmission having an independent flow control valve and an engine clutch cooling channel for the cooling of an engine clutch mounted thereon. The method includes a hybrid starter generator (HSG) state determination step of determining a state of an HSG, a driving motor cranking execution step of cranking an engine using a driving motor when the state of the HSG is a state in which the HSG does not operate in the HSG state determination step, and a cooling execution step of supplying an additional flow to the engine clutch cooling channel by driving the independent flow control valve, wherein the cooling execution step is performed simultaneously with the driving motor cranking execution step.
