Start-stop control method and device for spreading vehicle of feeding machine

The invention provides a starting and stopping control method and device for a spreading vehicle of a feeding machine. The method comprises the steps that S1, a control module obtains the amount of materials in a bin of the feeding machine and the position of the spreading vehicle of the feeding machine; S2, when the control module detects that the amount of the materials in the bin of the feeding machine is larger than a set amount of the materials and the position of the spreading vehicle of the feeding machine deviates from a preset area in the forward direction, the step S3 is executed; when the control module detects that the amount of the materials in the bin of the feeding machine is smaller than the set material amount and the position of the spreading vehicle of the feeding machine deviates from a preset area in the reverse direction, the step S4 is executed; S3, the control module controls conveying equipment of the previous procedure so as to reduce the material flow input into the bin of the feedi
