This study takes an E-REV as example, and carries out the parameters matching analysis and related experimental study of powertrain, which includes the electric propulsion system, the electric energy storage system, the fuel-powered electric generator and the control modes of battery pack. Using the co-simulation of Matlab/Simulink and Advisor, the power performance of the E-REV was simulated in the NEDC driving cycle. The simulation and test results show that the definite scheme of powertrain can meet the primary performance requirements of E-REV.

This paper investigates the control strategy of engine smart start/stop system, and develops the simulation model of the micro car equipped with smart start/stop system in Matlab/Simulink environment. The schematic and the starting process dynamics of the engine smart start/stop system are analyzed. The simulation results of the fuel economy between the baseline vehicle and the vehicle after installation of smart start/stop system are discussed using Matlab and ADVISOR software co-simulation in the NEDC driving cycle. Finally the test of engine start and the emissions test of the micro car equipped with smart start/stop system are conducted using standard chassis dynamometer. The results indicate that the engine of the micro car can be automatically shut off as it meets the conditions of engine automatic stop.
