摘要:A method for controlling the operation of turn signal indicator assemblies (S) ofa vehicle, comprising at least one lighting series (D1, D2) having at least one LED indicator(L) and at least one incandescent lamp (B), wherein the method comprises the steps ofapplying an intermittent electric voltage (V) having predetermined frequency (F) andperiod (T) to at least one lighting series (D1, D2), measuring a first value of the electriccurrent (I1) absorbed by the indicator series (D1, D2) during a first predetermined sub-period (T1), generating an electric parameter (P) associated with the first value ofabsorbed electric current (I1), defining a reference electric current value (IRIF), a step ofmeasuring a second value of the electric current (12) absorbed by the series (D1, D2) in asecond sub-period (T2) separate from the first, comparing the parameter (P) of absorbedelectric current with the reference value (IRIF) to generate an error signal (E) andincreasing the frequency (F) of the voltage (V) in response to the error signal (E). Theparameter (P) is equal to the difference between the first (I1) and second (I2) values ofabsorbed current. A control device operating according to the above method.
