Development Of 16 Gears EPS System And CCS Control System

With the improving of standards of living,the traffic condition is continuously worsed.It is a puzzle for the conveyance company and transportations manage department how to lower the driver's tiredness,make the process of shift gear more econmic and comfortable.Using the research experience for reference in home and abroad,and according to our national actual situation, we developed an Electronic Pneumatic Shift System that has a good cost performance ratio.Based on the 16S2200 gear box, which is produced by QIJIANG Transmission,the machine is redesigned and the manual gear box is replaced by the electronic transmission. The system takes the ECU as the control kernel and utilizes the method of the Electronic Pneumatic Shift to complete the prospective shift operation. This system can not only maintain simple structure and high efficiency, but also have high manufacture facility and high performance-price proportion. So this project has important academic significance and applied value.This thesis firstly summarized the reality in practical vehicle shift technology :including the characteristics,the advantages and disadvantages, then the blue print of whole system is expounded. Based on the mechanical structure, this thesis has also expoudsed its system composition,including electronic control unit, the circuit design of prior channel system and the circuit design of backward channel system. As the shift system achieve the electronic,we can easily add various modules. In this thesis to further improve the vehicle's comfort and fuel characteristics,we add cruise control system,which is based on Cummins engine.Finally the hardware and software are testd to make sure the whole system can work smoothly.
