Abstract

a presente invenção refere-se a um método de controlar um sistema de direção assistida que compreende pelo menos uma função de controle de curso (f1), pela qual um setpoint de posição (¿réf) é determinado automaticamente de acordo com um curso de referência que um veículo deve ser orientado a seguir, então um setpoint de motor (cmot) aplicado a um motor de assistência (2) é consequentemente ajustado, o dito método compreendendo uma função de segurança (f2) que é distinta da função de controle de curso (f1) e encontra um nível de segurança asil maior, de acordo com o padrão iso-26262, a dita função de segurança (f2) compreendendo um subfunção de diagnóstico (f2-1), de acordo com a qual um parâmetro de controle (¿volante, ccond, ¿volante) tal como a posição angular do volante (¿volante), o torque de condutor aplicado ao volante (ccond), ou a taxa na qual o volante é girado (¿volante) é monitorada, a fim de detectar o início de uma situação de alerta considerada perigosa, então uma subfunção de intervenção (f2-2) de acordo com a qual, se uma situação de alerta for detectada, a função de controle de curso (f1) é neutralizada.
