title = "Functional Analysis Method for Dynamic Speed Ratio Control of CVT-Based Vehicles",
abstract = "Speed ratio control of CVT-based vehicles is critical to vehicle dynamic performance. With vehicle accelerating, transmission efficiency and rolling resistance coefficient vary at real-time. Considering real-time variables into speed ratio control, functional analysis method is proposed. Choosing speed ratios as functional argument, a general functional form of acceleration time is established. The performance index is strongly nonlinear, which makes it difficult to obtain theoretical optimal solutions. So hybrid function of genetic algorithm with fmincon is adopted to obtain the numerical solutions. Continuously variable transmission model is established to compare the dynamic performance in different strategies. The simulation results show that accelerating time of 0–90, km/h decreased by 2.31, s after optimization,realizing the application of Functional Analysis Method on CVT ratio control problems.",
