Abstract

Abstract: In order to reduce the emissions of the plug-in series hybrid electric vehicle (PSHEV) during the cold start phase, a vehicle model on PSHEV is established and a dynamic model of electrically heated catalyst system (EHCS) based on optimization and control strategy of engine start-stop is built. The PSHEV energy management control strategy based on EHCS preheating is proposed. The influence of different pre-heating power on EHCS temperature is simulated. By comparing SOC value of the control strategy with the original control strategy; and comparative analysis of cold start emissions of three elements catalyst under three strategies of pre-heating, post-heating and non-heating; it is found that PSHEV with 2kW preheat 150s engine start and stop optimization of the control strategy can reduce the cold start HC / CO emissions at price of a small fuel consumption costs.
