PROBLEM TO BE SOLVED: To provide a travel state simulator capable of achieving simulation of vehicle travel assuming a wavelike road, in a vehicle performance inspection. SOLUTION: A test system simulates the vehicle travel state by absorbing a driving output of an engine 10 or a motor generator 20 with load absorbing motors 50a and 50b directly connected to a drive shaft 40 without mounting a brake system to be mounted to an actual vehicle. A travel simulator 60 calculates a wavelike road travel torque according to a virtual travel distance of the vehicle and the wavelength and height of the wavelike road constituting the wavelike road shown in a driving condition, and calculates a load torque according to the driving condition including the wavelike road travel torque. The load absorbing motors 50a and 50b are controlled according to the calculated load torque. COPYRIGHT: (C)2006,JPO&NCIPI
