PROBLEM TO BE SOLVED: To prevent unnecessary changing of a gear ratio of a transmission by suppressing changing of the gear ratio of the transmission in a situation wherein traction control is carried out. SOLUTION: During traction control, first corrected target driving force Fp_t_future_trc1 is calculated on the basis of target driving force Fp_t_now_trc of traction control, and second corrected target driving force Fp_t_future_trc2 preventing changing of a speed stage of the transmission 16 is calculated on the basis of a driving demand of a driver and a friction coefficientμof a road surface. Of the first and second corrected target driving force, a value of the larger one is set as corrected target driving force Fp_t_future_trc of traction control, an engine is controlled on the basis of the target driving force Fp_t_now_trc, and a speed stage of the transmission 16 is controlled on the basis of the corrected target driving force Fp_t_future_trc.
