Abstract
método para segurança do torque de assitência suprido por um motor de assistência elétrico em um sistema de direção hidráulica de veículo motor. a invenção refere-se a um método para segurança do torque de assistência (15) suprido por um motor de assistência elétrico (8) em um sistema de direção hidráulica de veículo motor, o método de segurança sendo caracterizado pelo fato de que compreende as etapas de: estimativa da força na cremalheira de sistema de direção a partir do torque excercido pelo condutor no volante de direção (2), a partir do torque de assitência (15), e opcionalmente a partir de outros parâmetros, tais como a velocidade do motor de assistência elétrico; comparação de um torque de assistência alvo com uma variação de assitência autorizada, definida em relação à força de cremalheira estimada (17) a qualquer momento, e no caso em que o torque de assistência alvo é mantido acima dos limites predefinidos para uma duração predefinida, correção e opcionalmente interrupção da direção hidráulica.
