Abstract

PLATAFORMA DE POTÊNCIA COM DIREÇÃO DE QUATRO RODAS/DIREÇÃO TRASEIRA. Um dispositivo para dirigir uma máquina agrícola com eixos dirigíveis independentemente inclui primeira e segunda interface de eixo dirigível para acoplar com um primeiro mecanismo de direção de um primeiro eixo dirigível e um segundo mecanismo de direção de um segundo eixo dirigível. O dispositivo inclui um módulo de planejamento com um caminho de guiamento para a máquina agrícola, e um módulo de controle de direção para coordenar a direção dos mecanismos de direção. O módulo de controle de direção inclui um comparador translacional para determinar uma diferença translacional entre uma localização de máquina agrícola em relação ao caminho de guiamento, um comparador angular para determinar uma diferença angular entre uma orientação angular da máquina agrícola em relação ao caminho de guiamento, e um controlador de direção de translação para atuar os primeiro e segundo mecanismos de direção de acordo com a diferença translacional. O dispositivo inclui um controlador de direção angular para atuar o segundo mecanismo de direção de acordo com a diferença angular.
