This application enables various kind of actual running tests for an engine transmission using a car body and a tire model. A dynamometer and a model with low inertia and high output can simulate various kinds of road surface conditions, such as hill start or slip-driving on a low friction test road.
The simulation including engine explosion fluctuation can be performed by the low inertia dynamometer and engine model on driving side. On the intake side, actual running test simulation using a car body and a tire model is performed for the HEV transmission. The battery model controls SOC to manage the battery simulator. It interfaces with each ECU for regenerative cooperation control when braking.
