Abstract
The present invention is one that enables an actual vehicle run on a chassis dynamometer to be reproduced in a vehicle drive train test, and includes: a loading device to be connected to a rotating shaft of a vehicle drive train; and a load controller that controls the loading device to change a load. In addition, the load controller includes a relationship data storage part adapted to store speed-load relationship data indicating the relationship between rotation speed of the loading device and a load corresponding to the rotation speed, and changes the timing of the load to be given by the loading device correspondingly to the rotation speed of the loading device with respect to timing determined by the speed-load relationship data. Alternatively, the load controller changes the load correspondingly to the rotation speed of a roller mounted with a tire in the chassis dynamometer.
