PROBLEM TO BE SOLVED: To improve fuel economy by surely preventing an engine restart which is not intended by a driver after a start of the engine automatic stop control of an idle stop.SOLUTION: A control processing part 6 starts the automatic stop control of an engine, and requires an E/GECU 8 to stop the engine by considering that an engine automatic stop condition is established when a vehicle speed V is equal to or lower than Vs (for example, 7 km/h), and brake fluid pressure becomes equal to or higher than 0.5 MPa being a first threshold. The control processing part 6 also requires the E/GECU 8 to restart the engine by considering that an engine restart condition is established when the brake hydraulic pressure becomes equal to or lower than 0.1 MPa being a second threshold. Furthermore, the control processing part 6 takes in a signal corresponding to deceleration from a G-sensor 9, and sets the second threshold of the brake fluid pressure being the engine restart condition to a lower value as deceleration at a start of an engine automatic stop as a deceleration degree at the engine automatic stop becomes higher on the basis of the taken-in signal. |
