Testing and Analysis of the Control Strategy of Honda Accord Plug-in HEV

PHEVs have shown their potential to further reduce fuel consumption and emissions, and many OEMs have put forward their mass-produced PHEV models. However, the series-parallel configuration PHEVs are seldom seen in the market. This paper discusses the testing and analysis of a Honda Accord PHEV, whose powertrain configuration is series-parallel. The NEDC cycle test, dynamic acceleration test, and static cruise test are finished in a four-wheel drive chassis dynamometer at the China Automotive Engineering Research Institute. Powertrain configuration design, control strategy, and fuel economy of the vehicle are analyzed. The test results show that the series-parallel configuration has the potential to reduce transmission mechanical losses, and the series operating mode tends to be more efficient in most working conditions.
