Patent ID: 7681545

Claim:
A starting apparatus for an internal combustion engine, which is mounted on an automobile to automatically start the internal combustion engine after an auto stop of the internal combustion engine with fulfillment of the auto stop condition including accelerator off and brake on, when the auto start condition including accelerator on or brake off is fulfilled, said starting apparatus comprising: a cranking module that is always connected to an output shaft of the internal combustion engine via a power transmission member and cranks the internal combustion engine through actuation of a rotating shaft, which is interlocked with rotation of the output shaft; a reverse rotation presumption module that determines a reverse rotation state of the internal combustion engine based on the measured revolution speed of the internal combustion engine, wherein the reverse rotation state is a reverse rotation of the internal combustion engine due to the incompletion of a compression cycle immediately before stopping of the internal combustion engine when the internal combustion engine is auto stopped with fulfillment of the auto stop condition; and a cranking control module that controls said cranking module when the auto start condition is fulfilled when the internal combustion engine is auto stopped with fulfillment of the auto stop condition, wherein, when the internal combustion engine is not in the reverse rotation state, the cranking control module controls the cranking module to crank the internal combustion engine, and wherein, when the internal combustion engine is in the reverse rotation state, the cranking control module controls the cranking module to crank the internal combustion engine after the internal combustion engine is not in the reverse rotation state.
