Optimization of Powertrain for Large Commercial Vehicle for Passenger Transportation Based on Optimus

Abstract

In this paper, an simulation program of power performance and fuel economy of large commercial vehicle for passenger transportation is programmed, and high credibility of the program is validated by experiment verification. Comprehensive fuel consumption is firstly introduced as the objective function, joint optimization of powertrain parameters is performed by using multi-disciplinary optimization platform Optimus and MATLAB. The result shows optimization efficiency is greatly improved and the outcome has great satisfaction.
