Abstract (en)

[origin: EP2037118A2] A target rotation angle of a crank angle between a crank angle stored upon stoppage of a crankshaft (8) and a reference position (45b) is computed. Then, the presence of a failure in the starting means (20) is determined based on whether a missing tooth part (45b) is detected when the crankshaft (8) rotates by the target rotation angle from the rotation stop position of the crankshaft (8) after an engine (1) is started by a starting means (20). If the missing tooth part (45b) is not detected when the crankshaft (8) rotates by the target rotation angle from the rotation stop position of the crankshaft (8), it is determined that the starting means (20) has a failure because there is a high possibility of a reverse rotation of the crankshaft (8) due to a failure in the starting means (20).
