Abstract
An ECU avoids engine stall by putting a compressor into a stationary state in a case where the rotation speed of a crankshaft is equal to or less than a predetermined speed during an idle operation of an internal combustion engine. During the idle operation, the ECU calculates a total load torque applied to the crankshaft by the compressor and an alternator. The ECU calculates the maximum torque of the internal combustion engine during the idle operation based on a target speed during the idle operation. Then, the ECU raises the predetermined speed in a case where the value obtained by subtracting the load torque from the maximum torque is equal to or less than a predetermined value.
