Simulation and Matching for the Powertrain System of Saloons
Reasonable match of the powertrain system is an optimized design process, which makes the saloons fuel economy low and power performance good. This document simulates the complete vehicle performance model of a specified manual transmission FF saloon by means of CRUISE. Establish 4 kinds of simulation task, select 3 kinds of engine whose displacement are 1.3 liters, 1.1liters and 1.0liters, 4 kinds of transmission and 4 kinds of main decelerator, calculate the power performance and fuel economy of saloon with 48 different kinds of alternative schemes on transmission system by CRUISE and analyze all the simulation results. A synthetic weighting index evaluation system of complete vehicle performance is created, which contains the design of evaluation indices and weighting indices. Analyze the weighting indices to obtain 5 design schemes which are superior to others. It offers reference data for saloon performance.
