Starter for engine equipped with motor generator |
摘要 |
A starter for an engine equipped with a motor generator achieves lower cost and reduced sizes and capacities of circuit elements by reducing the assist load on the motor generator: it is provided with a motor generator (2) and a starting motor (10) connected to an engine (1); a startup state determining circuit (20) which determines the startup state from operating condition and selectively issues ON signals M1 and M2 to the motor generator and the starting motor; a key switch (6) which generates a start signal (Qe) at the time of starting the engine; and a temperature sensor 12 which generates a temperature signal (Te) corresponding to the temperature of the engine. The startup state determining circuit actuates only the motor generator as a motor in a startup state wherein the temperature signal indicates not less than a predetermined temperature corresponding to the warm-up state of the engine, while it actuates both the starting motor and the motor generator in a startup state wherein the temperature signal indicates a temperature below the predetermined temperature. And the startup state determining circuit actuates the starting motor first, then actuates the motor generator after a delay time corresponding to a rush current period of the starting motor has elapsed in the second startup state.
