PURPOSE:To achieve a higher reliability in various tests of a vehicle, by calculating changes in the running resistance value generated with variations in vehicle weight shared by wheels during the accelerating of a vehicle to ensure the reproduction of a running resistance value. CONSTITUTION:When a load is generated corresponding to a running resistance value with a load simulator engaged with a four wheel driven type vehicle, front and rear wheels of a vehicle to be tested or driven wheel systems thereof are engaged with corresponding control sections 61, 62, 71 and 72 in a load control section 2 of the load simulator and a command value of the load control section 2 is provided as running resistance value of the vehicle being tested to control a load generated. Then, the acceleration of the vehicle being tested is measured to calculate variation of respective support vehicle weight on front and rear wheels of the vehicle being tested based on the acceleration thereof. A function item of a load is corrected in the command value of the load control section 2 based on the variation thus obtained.
