Abstract

Methods and systems for detecting and clearing battery power failure of an electric clutch actuator (ECA) include use of a capacitor connected to the ECA. The capacitor is connected to the ECA such that when the ECA and a battery configured to output a battery voltage are connected together a capacitor voltage matches the battery voltage and when the ECA and the battery are disconnected from one another the capacitor voltage differs from the battery voltage. A loss of battery connection is detected upon a difference between the capacitor voltage and the battery voltage exceeding a threshold.
