PROBLEM TO BE SOLVED: To reduce discomfort which is applied to a driver due to groan sound.SOLUTION: When an idling stop finish condition is established, an idling stop ECU starts pressure reduction control of a brake oil based on a second pressure reduction map M2 at a complete explosion detection timing of an engine, if an inclination angle α of a vehicle body is equal to or more than a set inclination angle α0 in a drop direction, and starts pressure reduction control of the brake oil based on a first pressure reduction map M1 at a timing of after engine rotation speed exceeds a peak, and before the engine rotation speed converges to target idling rotation speed, if the inclination angle α of the vehicle body is less than the set inclination angle α0 in the drop direction.SELECTED DRAWING: Figure 4 |
