PROBLEM TO BE SOLVED: To prevent overshoot of a throttle valve by limiting a rapid change in the change amount of a target opening caused by the rapid closing operation of a throttle grip. SOLUTION: A target TH opening degree change amount calculating section 26 calculates the change amount of a target throttle opening degreeΔTHCMD. In accordance with whether or not the change amount of the target throttle opening degreeΔTHCMD is not less than a predetermined control start threshold, a collision prevention process determining section 27 determines whether the 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 section 28 calculates a change-amount basic value of the target throttle opening degree. A correction term calculating section 29 inputs to a multiplying section 30 a correction term for correcting the change-amount basic value. The multiplying section 30 multiplies the change-amount basic value by the correction term, and outputs the change amount of the target throttle opening degree. The correction term can be set to have a value not more than 1.0 in accordance with the target TH opening degree. COPYRIGHT: (C)2011,JPO&INPIT
