PROBLEM TO BE SOLVED: To quickly and surely suppress pitching even if a pitching phenomenon occurs to an electric vehicle during stop. SOLUTION: A speed command ω<SP>*</SP>corresponding to a depressed amount of an accelerator 10 is outputted from an accelerator input processing part 101. A pitching detection part 104 detects the pitching on the basis of a detection speed ω during stop. When the pitching is not detected, a speed command adjusting part 105 outputs the speed command ω<SP>*</SP>from the accelerator input processing part 101. When the pitching is detected, the speed command adjusting part 105 outputs the speed command ω<SP>*</SP>with a zero value. A PI calculation part 201 outputs a torque current command Iq by executing PI calculation to a difference Δω between the speed command ω<SP>*</SP>and the detection speed ω even during stop. The PI calculation part 201 generates force for canceling the pitching operation by vector-controlling an induction motor 30 for traveling corresponding to the torque current command Iq.
