Automatic Transmission Controller Using State Flow
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 4
Abstract
Hydraulic technology can be used to capture and transfer high levels of energy extremely quickly and have a longer operating life compared with similarly sized electric systems. The hydraulic hybrid vehicle (HHV) includes two power sources that propel the vehicle: a fuel-efficient diesel combustion engine and hydraulic components. This technology replaces a conventional drive train with a hydraulic one, which eliminates the need for a mechanical transmission and driveline. To explore an optimal gear shifting strategy with best fuel economy for a seven-speed automatic transmission used on a hydraulic hybrid vehicle, a strategy is designed with a highest possible gear criterion as long as the torque requirement can be satisfied, except for braking process and torque demanding situations. The optimization strategy takes several other criteria into consideration, such as high motor displacement criterion, to improve efficiency and fuel economy. Then the optimization strategy is developed on the basis of these criteria from two main aspects of the existing SIMULINK truck model. One approach is based on the hydraulic.
