Abstract: This paper analyzes the energy consumption of different transmission actuating system concepts. The mathematical models are established for the energy consumption of four schemes: large displacement mechanical pump, small displacement mechanical pump+electronic pump, electronic motor+electronic pump, and double electronic pump. Taking the dual clutch transmission (DCT) as an example and based on the new European driving cycle (NEDC), the energy consumption of the four concepts are calculated. This article analysis the benefits of the different solutions, providing information on the selection of transmission actuating system solutions.
