A traffic-in-loop powertrain simulation framework, aiming at real time driving simulation validation, is presented in this paper. Traffic scenario and powertrain model are built in different platforms with capability of information interchange. This bidirectional co-simulation is capable to imitate I2V (infrastructure to vehicle)communication, connected vehicle communication and to capture driver behavior under stochastic traffic environment. With these real driving information, interaction influence between traffic and powertrain could be reflected online. An application example of optimal control design for diesel engine with after-treatment system is illustrated. Simulation validation on deterministic and stochastic traffic scenario are conducted, respectively. It could be concluded the necessity of onboard control scheme for powertrain in real-world traffic consideration.
