SYSTEM FOR CRANKING INTERNAL COMBUSTION ENGINE BY ENGAGEMENT OF PINION WITH RING GEAR
First Claim
1. A system for driving a starter with a pinion so that the starter rotates a ring gear coupled to a, crankshaft of an internal combustion engine to crank the internal combustion engine during a drop of a rotational speed of the crankshaft by automatic-stop control of the internal combustion engine, the system comprising:
- a predictor that predicts a future trajectory of the drop of the rotational speed of the crankshaft based on information associated with the drop of the rotational speed of the crankshaft; and
a determiner that determines a tuning of the driving of the starter based on the future trajectory of the drop of the rotational speed of the internal combustion engine.

Abstract
In a system for driving a starter with a pinion so that the starter rotates a ring gear coupled to a crankshaft of an internal combustion engine to crank the internal combustion engine during a drop of a rotational speed of the crankshaft by automatic-stop control of the internal combustion engine, a predictor predicts a future trajectory of the drop of the rotational speed of the crankshaft based on information associated with the drop of the rotational speed of the crankshaft. A determiner determines a timing of the driving of the starter based on the future trajectory of the drop of the rotational speed of the internal combustion engine.

14. A system for driving a starter with a pinion to thereby shift the pinion to a ring gear coupled to a crankshaft of an internal combustion engine for restart thereof during a drop of a rotational speed of the crankshaft by automatic-stop control of the internal combustion engine, the internal combustion engine working to reciprocate a piston in a cylinder through a top dead center (TDC) of the cylinder to thereby rotate the crankshaft, the system comprising:
-
a last TUC determiner that determines, based on information associated with the drop of the rotational speed of the crankshaft, a timing at which the piston reaches a cast TDC in forward rotation of the crankshaft during the drop of the rotational speed of the crankshaft; and a driving timing determiner that determines a timing of the driving of the starter based on the timing of the last TDC in the forward rotation of the crankshaft during the drop of the rotational speed of the crankshaft. - View Dependent Claims (15, 16, 17, 18)
