A New Strategy to Optimize the Economy Performance of the New Power-Split Hybrid Transmission Platform CHS-HT2800

CORUN CHS has recently developed a new power-split hybrid transmission platform CHS-HT2800, which has added 2 clutches compared to CHS-HT1800. With involvement of 2 E-motors CHS-HT2800 has 9 forward gears, including 3 electric forward gears and 6 hybrid forward gears. Among the 6 hybrid gears 4 gears are fixed-ratio gears and the remaining 2 gears are eCVT gears. This paper describes a strategy, designed for CHS-HT2800, how to select the optimal mode, the optimal gear and the optimal work point of the engine to achieve the best economy performance in the real traffic. Because it is universally accepted, that the WLTC cycle can represent real world vehicle operation on urban and extra-urban roads, motorways, and freeways. The introduced strategy will be validated with the help of the WLTC cycle.
