A target TH opening degree change amount calculating unit 26 calculates a change amount of a target throttle opening degree DeltaTHCMD. In accordance with whether or not the change amount of the target throttle opening degree DeltaTHCMD is not less than a predetermined control start threshold, a collision prevention process determining unit 27 determines whether a throttle grip 21 has been operated to rapidly close. When the rapid closing operation of the throttle grip 21 is detected, a change-amount basic value calculating unit 28 calculates a change-amount basic value of the target throttle opening degree. A correction term calculating unit 29 inputs to a multiplying unit 30 a correction term for correcting the change-amount basic value. The multiplying unit 30 multiplies the change-amount basic value by the correction term, and outputs a change amount of the target throttle opening degree thus calculated. The correction term can be set, for example, to have a value not more than 1.0 in accordance with the target TH opening degree. |
