The　control　system　of　wheel　type　backhoe　loader　plays　an　important　role　in　its　operations.　In　order　to　enhance　the　reliability　and　efficiency　of　corresponding　construction　machine,　a　variety　of　field　control　bus,　for　example,　CAN　bus,　LIN　bus,　and　KWP2000　bus,　are　widely　applied　in　this　field.　In　this　paper,　the　CAN　bus　technology　is　applied　in　the　control　system　of　wheel　type　backhoe　loader.　Its　features　are　explored.　The　designing　scheme　of　typical　control　system　is　introduced.　Therefore,　the　architecture　of　the　control　system　of　wheel　type　backhoe　loader　using　CAN　bus　technology　is　constructed.　The　control　principles　and　functions　of　loading　and　excavating　operation　as　well　as　failure　alarm　scenario　of　wheel　type　backhoe　loader　are　analyzed.　Then,　the　characteristics　of　the　control　system　of　wheel　type　backhoe　loader　are　illustrated.　Finally,　the　practical　implementation　of　CAN　bus　control　system　in　wheel　type　backhoe　loader　is　carried　out.
