Abstract
In a vibration control apparatus for a vehicle driven by an electric motor at least, a first target torque is calculated from a vehicle operating condition such as an accelerator opening, and a second target torque is calculated from at least a sensed motor speed by using a model H(s)/Gp(s) composed of a transfer characteristic H(s) which is greater than or equal to a transfer characteristic Gp(s) in an order difference between the order of a denominator and the order of a numerator. A torque control section controls the motor to bring an actual output torque of the motor closer to a command motor torque determined from the first and second target torque.
