A method and a control unit for determining and handling a varying load being applied to a component are presented,the method includes:- determining a signal Sload representing the varying load;- determining extreme values Sextr_1, Sextr_2, ..., Sextr_k for the varying load signal Sιoad;- storing the extreme values Sextr_1, Sextr_2 , ..., Sextr_k ln a buffer memory;- determining that at least one closed cycle is included in the varying load signal Sιoad, the determining of each included closed cycle being based on three consecutive extreme values Sextr_k-2, Sextr_k-2, Sextr_k stored in the buffer memory;- determining at least one cycle representing value Scycle_1, Scycle_2 , ..., Scycle_n related to the at least one determined closed cycle, respectively;- storing the determined at least one cycle representing value Scycle_1, Scycle_2 , ...,Scycle_n in at least one closed cycle data memory;- deleting at least one of the three consecutive extreme values Sextr_1, Sextr_2, ..., Sextr_k of each determined closed cycle from the buffer memory; and- performing at least one action based on at least one cycle representing valueScycle_1, Scycle_2 , ..., Scycle_n stored in the at least one closed cycle data memory.
