Study on fuzzy automatic transmission schedule of different throttle position for vehicle

In this paper we study on automatic transmission method of vehicles in different throttle utilizing fuzzy technology. The hardware is PLC and HMI etc, the software is fuzzy rule. It is difficult to set up exact mathematic model, using practice experience of driver to form the fuzzy control rules in different throttle . The rules are stored in PLC`s memorizer and it come true controlling of vehicle automatic transmission. The result of experiment showed that ,in different working load ,the controller can select another the fuzzy strategy in different throttle, this method has the best anti-jamming and realizing is simple and having ideal transmission quality.
