PROBLEM TO BE SOLVED: To make torque to be controlled follow even transient changes of target torque with sufficiently satisfactory responsiveness. SOLUTION: A running resistance torque computation part 91 computes the amount of shaft torque corresponding to running resistance to be added to a test vehicle. A vehicle inertia torque computation part 98 computes the amount of shaft torque corresponding to an inertia force to be added to the test vehicle. A first adder 92 adds the two computed amounts of torque to be target torque. A feedforward control part 99 determines the amount of a current to be controlled of a motor 3 in which the shaft torque is estimated to be the target torque. A feedback control part 94 determines the amount of adjustment of the amount of the current to be controlled of the motor 3 for reducing error signals acquired by subtracting shaft torque signals TQ outputted by an shaft torque meter 6 from the target torque at a second adder 93. A third adder 95 adds the amount of control and the amount of adjustment to be control signals. A vector control part 96 performs vector control of an inverter for driving the motor 3 in such a way that the motor 3 may be driven by a current to be controlled indicated by the control signals.
