On-time data exchange in fully-parallelized co-simulation with conservative synchronization

Abstract

Trade-offs between simulation speed, fidelity, compatibility, and scalability limits the use of accurate high-resolution simulators in the automotive industry. With a growing demand for fuel-efficient and environmentally friendly vehicles, the need for precise co-simulation of entire vehicle is greater than ever before. In this paper we present a technique for distributed discrete event co-simulation that exploits parallel computing and distributed simulation with an advanced synchronization technique to overcome all of these constraints. The system allows us to add new components with their own solvers to a simulation without compromising the solution accuracy or simulation speed. © 2013 IEEE.
