Abstract

See full text

A method for starting an internal combustion engine (ICE) having a crankshaft and an electric turning machine (ETM) operatively connected to the crankshaft is disclosed. The method includes: sensing a voltage of a capacitance connected to the ETM and configured to power the ETM; detecting a rotation of the crankshaft resulting from an actuation of a recoil starter; in response to detecting the rotation of the crankshaft, determining if an assisted start condition is met; in response to the assisted start condition being met, delivering power from the capacitance to the ETM and the ETM assisting the recoil starter; in response to the assisted start condition not being met, continuing to turn the crankshaft with the recoil starter without assistance from the ETM; determining if the ICE has started; and in response to the ICE being started, delivering power from the ETM to the capacitance.
