This paper puts forward a research design method of pure electric vehicle automatic transmission shift schedule based on the urban road conditions in connection with the problems of the low average speed, the high percentage of idle, and frequently shifting in pure electric vehicle. In order to improve the performance of pure electric vehicle automatic transmission and the using efficiency of the motor, this paper formulates a fuzzy shift schedule in the view of the economy. At the same time, this paper supplies a vehicle simulation in the view of economy through a application instance and the MATLAB / SIMULINK / ADVISOR software. The simulation results show that the fuzzy shift strategy can meet the requirements of the economy very well.

European Union legislation sets mandatory emission and fuel consumption reduction targets for new vehicles and therefore economy remains a key challenge for automotive engineers. Optimizing the transmission shift schedule for an automatic transmission with double clutch is an important part of improving fuel economy. Using simulation and optimization algorithms can ensure that a truly optimal shift schedule is implemented. The main objective of this paper focuses on study the performance of a vehicle with a dual clutch transmission (DCT), with special emphasis on optimizing the shifting schedule using optimization algorithms. In order to study and simulate the shifting strategy the dynamic model is developed based on an existing model in MATLAB Simulink software. In the first phase of the paper a detailed description of the DCT technology, its main functional components and dynamic characteristics are explored. In the second phase model development and simulation concerns the major part of this work, to find the optimal shift schedule for different engine speed and engine torque as it accelerates through the transmission gears by engaging the dual clutches. Finally, the simulation results were evaluated and presented which successfully demonstrate the performance improvement of a dual clutch transmission with an optimized shifting strategy.

In this paper, the gear-position decision method based on 3-parameter the optimal economical shift schedule for Automatic Manual Transmission (AMT) of Parallel Hybrid Electric Bus (PHEB) is proposed. Vehicle simulation model was built by using ADVISOR simulation software. The simulation results show that 3-parameter shift schedule has improved in economical performance of PHEB compared with 2-parameter shift schedule.
