Fossil fuel depletion risk forecasting and growing environmental concerns are strong impetus for developing higher efficient transportation system nowadays. Hybridization is considered as one of the most efficient short and mid-term solutions. In particular, series hydraulic hybrid configuration provides a further advantage when it provides more degree of freedom of engine control. However, low energy...
To simplify the modeling process and to increase accuracy and stability of CVT ratio control system, CVT transmission structure and ratio changing theory were analyzed. The mathematical model every part of control system was built. Engine simulation model and CVT object ratio simulation model based on the engine optimal-economy and the optimal-power work mode were built. CVT-vehicle model according...
