A chassis dynamometer is arranged to test a vehicle operated thereon so as to follow up a target vehicle speed. A controlling system determines a load as a command torque from a detected actual vehicle speed of the vehicle on the chassis dynamometer and controls a running resistance of the vehicle by controlling a dynamometer unit in accordance with the load. The controlling system comprises a monitoring section for detecting an abnormal condition indicative of a vehicle's disability to follow up the target speed by monitoring a speed deviation between the detected actual vehicle speed and the target speed, and a correcting section for correcting the command torque to reduce the speed deviation when the abnormal condition is detected. <IMAGE> |
