Whether the present engine load KLSM is less than a lower limit value L1 or not is decided (S305). In this case, ISCV opening DOP is increased and a value of the map corresponding to the present engine speed is corrected by using the DOP after the correction (S306). When the engine load KLSM is the lower limit value L1 or more, whether the present engine load KLSM exceeds a lower limit value L2 or not is decided (S307). When the engine load KLSM does not exceed the lower limit value L2, the ISCV opening DOP is reduced and the map is corrected.
