Abstract
A stop control apparatus is applied to an internal combustion engine (11) whose crankshaft (11a) is connected to an input shaft (15) via a torsional damper (14), wherein the direction in which the crankshaft (11a) rotates while the operation of the internal combustion engine (11) is assumed to be the positively rotating direction, and a state of the torsional angle of the torsional damper (14) when the crankshaft (11a) is advancing in the positively rotating direction with respect to the input shaft (15) is assumed to be positive. When a predetermined engine stop condition is satisfied, a stop control for outputting torque from a first MG (12) such that the crankshaft (11a) decelerates is executed. The timing at which the torque is output from the first MG (12) is controlled such that the positive peak of the torsional angle of the torsional damper (14) occurs in the expansion stroke of the internal combustion engine (11).
