PROBLEM TO BE SOLVED: To synchronize rotation speeds of a roller for front wheels and a roller for rear wheels. SOLUTION: A speed synchronous controller 522 generates a speed difference adjusting signal for adjusting the generated torque or rotation speed of a motor 22 so that the speed difference between the rotation speed VF output by a tachometer 27 of a dynamometer 2 for front wheels and the rotation speed VR output by a tachometer 27 of a dynamometer 3 for rear wheels is zero. An acceleration synchronous controller 526 generates an angular acceleration difference adjusting signal for adjusting the torque component derived by multiplying the angular acceleration difference between the rotation speeds VF and VR by a rotational inertia mass of the dynamometer and the generated torque of the motor 22. Control parameter values of the motor 22 of the dynamometer 2 for front wheels and the motor 22 of the dynamometer 3 for rear wheels calculated by a travel resistance torque control block 51 are corrected so as to synchronize the rotations of both motors using a speed synchronizing signal formed by adding the speed difference adjusting signal to the angular acceleration difference adjusting signal with an adjusting signal adder 527.
