PROBLEM TO BE SOLVED: To acquire more suitable driving condition according to a malfunctioning state of an atmospheric sensor. SOLUTION: When the output signal of the atmospheric sensor is determined to be erroneous by determination of whether or not the atmospheric sensor 1 is in a signal error state, where its output value becomes a specific value (S102), a predetermined fixed value is used for controlling various behaviors as the output value of the atmospheric sensor 1 (S104). When the output value of the atmospheric sensor 1 is determined to be in a stuck state where the output value becomes fixed, by determination of whether the value is in the stuck state (S106); an output value, immediately prior to the determination of being in the stuck state is used as the output value of the atmospheric sensor 1 for controlling various behaviors (S108), and suitable driving condition in accordance with the malfunctioning state of the atmospheric sensor 1 is ensured.
