Abstract

An ECU executes a program including the steps of detecting a stroke amount SP of a clutch pedal, a value I of current flowing through a solenoid valve of a normally-closed type provided at a pipe coupling a master cylinder and a clutch release cylinder, and a stroke amount SC of the clutch release cylinder, and permitting performing of idle stop when a condition that the stroke amount SP of the clutch pedal is at least a threshold value SP(1), a condition that stroke amount SC of the clutch release cylinder is at least a threshold value SC(0), and a condition that value I of current flowing through the solenoid valve is not larger than a threshold value I(0) are all satisfied.
