Abstract

método de controle de direção e dispositivo de controle de direção. o dispositivo de controle de direção da presente invenção adquire a distância de um veículo até obstáculos detectados por um sensor de detecção de distância, calcula um primeiro ângulo de direção alvo de modo que o ângulo de direção para mover o veículo em uma direção para longe de um obstáculo localizado no lado esquerdo em relação à direção de deslocamento conforme o veículo avança aumenta à medida que a distância até o obstáculo diminui, calcula um segundo ângulo de direção alvo de modo que o ângulo de direção para mover o veículo em uma direção para longe de um obstáculo localizado no lado direito em relação à direção de deslocamento conforme o veículo avança aumenta à medida que a distância até o obstáculo diminui, soma o primeiro e o segundo ângulos de direção alvo para calcular um ângulo de direção final, e controla as rodas direcionais do veículo com base no ângulo de direção final.
