PURPOSE:To eliminate uncomfortable riding feeling by sequentially reducing driving forces of motors for driving a plurality of vehicles for composing a train, from a head at the time of power driving, or delaying generation of the force, sequentially reducing the forces from the rear at the time of braking, or delaying the generation of the force. CONSTITUTION:A plurality of (four in the drawing) induction motors 3 for individually rotating a plurality of drive shafts, are respectively driven by distribution type VVVF type inverters 5. The inverters 5 are controlled by an output signal of a logic device 6 to reduce driving forces of a head vehicle from the motor toward the following vehicle or to delay the generation of the force at the time of power driving. Or, at the time of braking, braking forces are reduced from the motor of the following vehicle toward the motor of the head vehicle or generation of the braking force is delayed. Thus, uncomfortable riding feeling due to push and pull of the vehicles therebetween at the times of power driving and braking of the vehicles, is eliminated. |
