APPARATUS FOR CONTROLLING CHASSIS DYNAMOMETER

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 observer and an ASR are designed on the basis of a controller design technique. A characteristic model in which characteristics of the restraint system and vehicle rigidity are determined for a transfer function is connected to an output side of the observer. A drive force signal calculated by the observer is input to the characteristic model. A running resistance command and a mechanical loss command are differential calculated by a subtraction unit from the output signal of the characteristic model. The resultant signal is input to an inertial unit, and is output to the ASR as a set electric inertial. COPYRIGHT: (C)2010,JPO&INPIT
