Abstract

trata-se de um sistema de controle que é configurado para receber um primeiro sinal indicativo de uma posição atual de um veículo e um segundo sinal indicativo de um caminho desejado para o veículo. o sistema é configurado para calcular um caminho virtual entre a posição atual e uma posição-alvo no caminho desejado e para emitir um terceiro sinal indicativo de comando de curvatura que corresponde a uma curvatura inicial do caminho virtual para fazer com que um sistema de controle de direcionamento do veículo ajuste um ângulo de direcionamento do veículo. o sistema é configurado para receber iterativamente uma posição atual atualizada, receber quaisquer atualizações em relação ao caminho desejado, calcular uma posição-alvo atualizada, calcular um caminho virtual atualizado com base na posição atual atualizada e no caminho desejado atualizado e emitir um comando de curvatura atualizado que corresponde a uma curvatura inicial respectiva do caminho virtual atualizado conforme o veículo percorre através de uma superfície.
