Abstract

Recently, the EPS increases as one of the items of the fuel efficiency equipped with the vehicle. To compare and verify the electric power consumption for the 14 V drive EPS and the 42 V drive EPS using simulation with EPS models on computers, and assess the advantages of the higher voltage system quantitatively.
