APPARATUS FOR TESTING VEHICLE BEHAVIOR

PROBLEM TO BE SOLVED: To solve the problem that a test with a transiently set mass cannot be performed when control response is not good and a test is not precisely performed because part of energy transiently generated in a vehicle is accumulated in a restraint system and a vehicle body in a chassis dynamometer system. SOLUTION: An ASR is designed on the basis of a controller design technique. A characteristic model in which characteristics of the restraint system and vehicle rigidity are determined with a transfer function is provided at an electric inertia control circuit. A drive force detection signal detected at a vehicle side is input to the characteristic model. A running resistance command and a mechanical loss command are subtracted from an output signal of the characteristic model and input to an inertial unit to calculate a set electric inertia signal. A differential signal between the resultant set electric inertia signal and an angular velocity detection signal is output to the ASR. COPYRIGHT: (C)2010,JPO&INPIT
