Abstract
An electric turning machine (ETM) operatively connected to an internal combustion engine (ICE) is operated as a motor with a first control strategy and as a generator with a second control strategy. In the first control strategy, electric power is delivered from a power source to the ETM selectively through at least one transistor of an electrical converter. After switching from the first control strategy to the second control strategy, the ETM delivers electric power to an accessory selectively through the at least one transistor of the electrical converter.
Claims19
A method for operating an electric turning machine (ETM) operatively connected to an internal combustion engine, the method comprising:
- operating the ETM as a motor with a first control strategy to increase a rotational speed of the internal combustion engine,
- operating with the first control strategy comprising delivering electric power from a power source to the ETM selectively through at least one transistor of an electrical converter;
- switching from the first control strategy to a second control strategy, the second control strategy being distinct from the first control strategy;
- and
- in response to switching from the first control strategy to the second control strategy, operating the ETM as a generator with the second control strategy,
- operating with the second control strategy comprising delivering electric power from the ETM to an accessory selectively through the at least one transistor of the electrical converter.
