First control unit performing first pseudo stepwise up-shift control that, in first travelling mode, increases vehicle speed while performing hold of transmission ratio and up-shift by first shifting speed and reduces engine torque upon up-shift, second control unit performing second pseudo stepwise up-shift control that, in second travelling mode, increases vehicle speed while performing hold of transmission ratio and up-shift by second shifting speed and reduces engine torque upon up-shift, and third control unit controlling change of travelling mode and switch between two pseudo stepwise up-shift controls according to control states of first and second control units, are provided. When travelling mode is changed to second travelling mode during progress of up-shift in first pseudo stepwise up-shift control, third control unit maintains first pseudo stepwise up-shift control until up-shift is completed. With this, harmonization between pseudo stepwise up-shift control and engine torque control is secured, then shift shock is suppressed.
