System for simulating power plant of automotive vehicle utilizing electrically powered high inertia power plant.

摘要

A simulation system for an automotive internal combustion engine is suitable for simulating an engine operation for performing bench test for an engine associated vehicular components, such as an automatic power transmission, an automatic transaxle, differential gear box and so forth. The system comprises a power plant which incorporates relatively high inertia, and means for compensating high inertia for achieving low inertia equivalent to the automotive internal combustion engine, an engine characteristics generator receiving predetermined engine operation parameter simulated data for deriving control signal commanding output torque of said power plant according to a predetermined engine output torque variation characteristics which is set in terms of said engine operation parameter simulated data, and means, responsive to a simulated engine environmental condition indicative data, for deriving a correction value based on said environmental condition for correcting said control signal. <IMAGE>
