PROBLEM TO BE SOLVED: To further improve effective fuel consumption of an idle stop vehicle.SOLUTION: In a control device, during idle-stopping an internal combustion engine, electricity is conducted to solenoid valves 61 and 62 existing on a hydraulic circuit for supplying a hydraulic pressure to braking devices 71, 72, 73, and 74 attached to wheels, so as to perform hill-hold control for blocking the hydraulic circuit with the solenoid valves and keeping the hydraulic pressure supplied to the braking devices. When a gradient of a rod on which a vehicle is located during idle-stopping and a magnitude of the gradient is lower than a threshold, the electricity is not conducted to one part of the solenoid valves. To determine whether or not the internal combustion engine during idle-stopping is restarted when the hydraulic pressure of the liquid flowing in the hydraulic circuit is compared to a determination value, a magnitude of the determination value is changed according to a case when the electricity is conducted to all of the solenoid valves and a case when the electricity is not conducted to some of the solenoid valves. |
