PROBLEM TO BE SOLVED: To prevent that an engine is restarted contrarily to a driver's intension, and to improve a fuel consumption reduction effect, in an idle stop vehicle.SOLUTION: When a &Dgr;t time (=two seconds) being a prescribed period elapses after a detection vehicle speed reaches 0 Km/h after the establishment of an automatic stop condition is confirmed by an idle stop control part (YES in step S1), a threshold of master cylinder pressure being a brake operation force for controlling an engine restart is changed and set to a higher restart threshold Tth2 (5.0 MPa) (step S3) from a restart threshold Tth1 (2.0 MPa), and when a brake pedal is increasingly pedaled in, and the master cylinder pressure being the brake operation force is raised higher than the changed higher restart threshold Tth2 (5.0 MPa), engine restart control is performed (step S5). |
