Shifting gears at conditions where the vehicle is running in terrine or at high torque and low RPM are instances that portray the complexity involved in making decisions. This requires running the vehicle at lower gears, therefore consuming more power. To take decisions in such conditions, implementation of fuzzy logic is required.
Apart from this, driving habits differ from person to person. It is identified that the SBC needs to get tuned to the driving habits with respect to shifting of gears and perform similarly. So there is a need for the system to be capable of learning the driving habits. Large SD card space and fast response of the python program and file handling capability to store the habits while in learn mode and execute the same in run mode is possible in the SBC ported with Linux and programs run on Python software. Also new algorithms can be developed according to the market demand, taste and utility of the upcoming trends. This is much similar to Android applications ported on the device for a certain utilities.
This article is the result of the work done as a part of academic interest in 1996 as a project for post graduation in Pune University. It was built around a basic microprocessor and was successfully completed. Fuzzy logic was also implemented to cater all the decisions to shift the gears. The concept is once again taken up to bring in versatility and flexibility with respect to precise functioning in shifting gears and mainly to project learning capability.
With respect to the performance of the vehicle, it was found that comfort associated to the reliving the strain in shifting the gears was achieved. This feature has added life to the concept were the vehicle movements, take off, overtaking method, acceleration and responses at the terrine roads was mimicked to the driver habits.
This approach is most recommended in both diesel and the petrol engine vehicles as it continuously monitors and tracks the performance of the gear box to operate efficiently. The load regulation is tightened from no load condition to the full load condition. When it comes to the application of automobile, this system caters a smooth pull, fast take off and counters unnecessary burning of fuel preserving the comforts in the vehicle.
