Abstract
A method for operating an electric turning machine (ETM) operatively connected to an internal combustion engine (ICE) are disclosed. An engine control unit (ECU) controls the ETM to operate as a motor with a first control strategy and as a generator with a second control strategy. The second control strategy is distinct from the first control strategy. The ECU controls switching the operation of the ETM from the first control strategy to the second control strategy when a sensor senses that a rotational speed of the ICE is equal to or above a minimum revolution threshold.
