Abstract

SISTEMA DE CONTROLE DE DIREçãO PARA UM VEìCULO Um sistema de controle de direção é provido para um veículo tendo um volante, rodas direcionáveis, e um atuador de direção hidráulica para controlar um ângulo de direção das rodas direcionáveis em resposta a um sinal de controle hidráulico. O sistema de controle de direção inclui uma válvula hidromecânica acoplada ao volante e gerando um primeiro sinal hidráulico como uma função de posição de volante, uma válvula eletro-hidráulica gerando um segundo sinal hidráulico com uma função de um sinal de controle eletrónico, uma unidade de controle eletrónica gerando o sinal de controle eletrónico, e uma unidade combinadora hidráulica que combina o primeiro e segundo sinais hidráulicos e provê o sinal de controle hidráulico para o atuador de direção hidráulica. O sistema de controle de direção também inclui um sensor de ângulo de volante, um sensor de taxa de quinalda, e um sensor de ângulo de roda guiada A unidade de controle gera um sinal de controle eletrónico com uma função dos sinais de sensor.
