Drivability and Fuel Economy Evaluation of a Sport Utility Vehicle Using CAE Tool
To establish accurate models for powertrain optimization of a Chinese sport utility vehicle Landwind X8,a powerful CAE tool GT-Drive was used to evaluate the vehicle drivability and fuel economy.Various proper models were established and vehicle performance was simulated,obtained results show that drivability of the vehicle is satisfactory in a macro sense,but fuel economy is moderate.Further comparison of simulated performance indices with field test data demonstrates that nearly 80% of the absolute relative errors are below 5%,the maximum absolute relative error is also less than 10%.Thus,the simulated data met well with the test data,it is confirmed that the established simulation models are validated and can be used as effective analysis tools in further powertrain optimization.
