Given the transmission efficiency fluctuation and response lag problem of hydromechanical continuous variable transmission combined with the complex and variable working environment of a tractor, an integrated control strategy of engine throttle compensation–hydromechanical continuous variable transmission speed regulation is adopted for dual-flow transmission control. On the basis of the estimation of working resistance, a fuzzy algorithm is used to design the throttle compensation law. Considering the maximum driving power of a tractor as the target of variable speed control, an hydromechanical continuous variable transmission efficiency model is established, and the control law of an hydromechanical continuous variable transmission displacement ratio with the maximum driving power of the tractor under any working condition is determined. On the basis of the wavelet neural network proportional–integral–derivative algorithm, the control law of the hydromechanical continuous variable transmission speed regulation is designed, and the parameters of proportional–integral–derivative control are corrected in real time during the control process. Based on MATLAB/Simulink modelling and simulation and the real vehicle verification test, results showed that the influence of hydromechanical continuous variable transmission efficiency fluctuation on the driving power of the entire vehicle, the response lag of the pump-controlled motor system, and the effect of the leakage on the variable speed control and the fluctuation of the working resistance are solved by studying the hydromechanical continuous variable transmission variable speed transmission control strategy. This strategy improves the stability of the tractor speed and ensured the quality of the work, thereby improving the ability of the tractor to adapt to complex working environments.

Abstract Many design parameters affect the performance of continuous variable transmissions. This paper presents the optimization of a continuous variable transmission by using the simulated annealing algorithm. The Bessel method of curve fitting and the tensor product method of surface fitting were used to facilitate the discrete fuel consumption, emissions of carbon monoxide (CO) and HC compound of experimental engine data. A compromise method was used to analyze the multi-objective functions. The values for design variables are recommended for further development.

Traffic Simulations

Vehicular tailpipe emissions have one of the largest impacts on urban air quality. One way to reduce these hazardous emissions is to reduce the amount of fuel consumed by on-road vehicles. In this research, we consider both vehicle design and driver behavior as crucial elements in evaluating the environmental impact of two-wheel vehicles. Any redesign of vehicle specifications, results in different driving patterns that need to be re-evaluated in a realistic environment with traffic simulation. Therefore we developed traffic simulations with mixed fleets to model scooter/driver behaviors to reflect urban driving scenarios. Based on the results, a 31-variable continuous variable transmission (CVT) design and a 14-parameter cellular automata traffic model are integrated. Simultaneous redesign of CVT with traffic simulation can reduce the fuel consumption by 16.2% in our case study. This promising outcome demonstrates the need for multi-discipline integration of real-world traffic impact assessments and improvements.
