After breath, current shift is corresponded to indicator light flicker by control gear display unit 300, and driver's gearshift is prompted to start to execute
Shift.When previous gear is switched to neutral gear by gear shifting actuating mechanism, neutral position state information is fed back to gear by entire car controller
Control unit 200, after shift control unit 200 receives the neutral position state information, control gear display unit 300 stops flicker simultaneously
Previous gear indicator light is closed, control neutral pilot lamp flicker prompts driver's gearshift to have switched to neutral position state.When changing
Gear executing agency is from neutral gear when switching to desired gear, and the gear shift operation information that is near completion is fed back to gear by entire car controller 400
Position control unit 200, shift control unit 200 receive gear shift operation and are near completion after information, control gear display unit 300
Stop flickering and close neutral pilot lamp, while controlling desired gear indicator light flicker, prompts driver that will switch to expectation
Gear.When gearshift complete gear shift operation, entire car controller 400 judge current shift whether with driver expectation gear one
It causes, if unanimously, gear shift operation completion information is fed back to shift control unit 200, shift control unit 200 receives shift behaviour
After making completion information, control gear display unit 300 stops flickering and lighting the indicator light of desired gear, prompts driver's shift
It finishes, speed changer has been in desired shifting state；If inconsistent, fault message is fed back to shift control unit by entire car controller
200, after shift control unit 200 receives the fault message of feedback, control gear display unit 300 controls all gear instructions
Lamp flickers, and prompts driver to shift gears and fails, needs parking checking immediately.
It if shifting commands are invalid, should not execute, then maintain current shift constant, and prompted by alarm unit.
Gear shift operation start information, neutral position state information, gear shift operation be near completion information, gear shift operation complete information,
Fault message can be collectively referred to as shift process information.
It is following to operate when carrying out the switching of section gear.
When speed changer some main shifting state in 1 to 6, driver operates the section gear of shift selecting unit 100
Position selecting switch (section gear upshift switch 710 or section gear kickdown switch 720), shift selecting unit 100 collect this
Operational order generates shifting commands.After shift control unit 200 receives shifting commands signal, which is passed by CAN bus
Entire car controller 400 is transported to, after entire car controller 400 receives the signal, according to current tractor whole vehicle information (current speed change
The information such as device gear, current power shift mode, current interval shifting state, Running Speed of Tractor, brake pedal state) it is comprehensive
Conjunction considers whether to execute instruction；If upshift or down shift demand are effective, entire car controller 400 drives related executing agency to start to hold
After row section gear upshift or downshift, section gear upshift or downshift success, new section shifting state information is fed back to gear
Control unit, shift control unit 200, which receives control gear display unit 300 after described information, to be lighted new section gear and refers to
Show lamp (810,820,830,840), driver is prompted to succeed upshift or downshift section gear.
Upshift or down shift demand are invalid, maintain current interval gear constant, and prompted by vehicle alarm system.
Section shifting state information is also shift process information.
Specific embodiment of the utility model is described above.It is to be appreciated that the utility model not office
It is limited to above-mentioned particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims,
This has no effect on the substantive content of the utility model.
