A method and device for a transport vehicle to automatically follow a harvester

Abstract

The invention provides a method for enabling a transport vehicle to automatically follow a harvester. The method comprises the steps: obtaining the speed of the harvester, the speed of the transport vehicle and the relative distance of a grain unloading cylinder of the harvester and the preset position of a rear cabin of the transport vehicle; based on the obtained speed of the harvester and the obtained speed of the transport vehicle, calculating the relative speed of the harvester and the transport vehicle; based on the relative distance, judging whether the current operation belongs to valid load or not; if being invalid load, generating distance to judge a result based on the relative distance; if being valid load, generating speed to judge the result based on the relative speed; obtaining the distance to judge the result; if the result judged based on speed is that the relative distance is more than zero, executing driving operation with the accelerated speed of the transport vehicle being a maximum value; if the result judged based on distance is that the relative distance is less than zero, executing the driving operation with the accelerated speed of the transport vehicle being adjusted to a minimum value. The method can relieve the work of a transport vehicle driver and solves the problem of neglected loading of crops caused by the importer driving of the transport vehicle driver.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and the specific invention patent relates to a method and a device for a transport vehicle to automatically follow a harvester. Background technique [0002] During the operation of the harvester, a transport vehicle (usually a truck) is often required to follow the harvester to load the crops harvested by the harvester. That is, one operation of the existing harvester requires two drivers to complete the operation, one driver drives the harvester for harvesting crops, and one driver drives a transport vehicle for loading crops. For the driver of the transport vehicle, it is necessary to keep the speed of the transport vehicle consistent with that of the harvester at all times, and keep the distance within a certain range. If the driver of the transport vehicle does not operate properly during the operation, it will cause crops to be missed. Therefore, need a kind of technical scheme that ...

Problems solved by technology

For the driver of the transport vehicle, it is necessary to keep the speed of the transport vehicle consistent with that of the harvester at all times, and keep the distance within a certain range. If the driver of the transport vehicle does not operate properly during the operation, it will cause crops to be missed.

Therefore, there is a need for a technical solution for the transport vehicle to automatically follow the harvester, so as to relieve the work of the transport vehicle driver and solve the phenomenon of missing crops caused by improper driving of the transport vehicle driver.
