Embodiment 1
[0036] Such as figure 1 As shown, a loader automatic transmission gear control method, including:
[0037] When the loader is in the climbing condition and the shift mode switch is selected as the automatic shift mode, obtain the gear change information of the gearbox;
[0038] In response to meeting the preset condition N in the upshift strategy table Kup , the gearbox is upshifted, the gearbox is upshifted from the current gear K to K+1 gear, the gear information of the K gear before the upshift and the K+1 gear after the upshift is recorded, and an instruction is issued to control the downshift strategy table The preset condition N of the original downshift from K+1 to K K+1Down Increase or decrease Δm, adjust to N K+1Down +Δm or N K+1Down -Δm, making it more difficult to downshift from K+1 to K;
[0039] Or, in response to meeting the preset condition N in the downshift strategy table KDown , the gearbox is downshifted, the gearbox is downshifted from the current gea...
