Hardware-in-the-loop, dynamometer based driver and vehicle simulator

摘要

To evaluate improvements in engine behavior, particularly with regard to engine management or aftertreatment systems, the engine should be operated in a representative vehicle over a standardized drivecycle. To achieve partial validation in an engine dynamometer test cell, the project described in this paper implements a driver and vehicle simulation which controls, in closed loop, a physical engine, clutch and dynamometer combination. The vehicle can be modeled with either a manual or automatic transmission, and package is implemented in the Matlab/dSPACE rapid prototyping environment.
