Method for protecting output stage of electric motor from overcurrent, for actuating clutch of dual clutch transmission in motor car, involves switching-off output stage when actual current value exceeds predetermined threshold value

摘要

The method involves actuating electromotor (5a) by the control device (3), for operating the clutch (5) such that the output stage (11) is switched over the shunt resistor (12) connected with the control device for measuring the actual current value. The output stage is switched off when the measured actual current value exceeds predetermined threshold value. The temperature sensor (14) is arranged on the circuit board of the output stage, for reporting the temperature of the output stage to the control device.
