| Abstract: | Authors research on developing of automatic gear shifting control system and its electronic control unit. Because of complexity of loader's gear shifting, a multi-mode control method is adopted which can coordinate operator and computer control functions. System's software program,hardware circuit and its reliability design are carried out.ECU's function and operation reliability are proved during bench and environmental tests.It shows that the system achieves gear-selecting and smooth gear-shifting control functions under different working modes. |
