Abstract

APARELHO DE DIREÇÃO ELÉTRICA. Um objeto da presente invenção é proporcionar um aparelho de direção elétrica que detecte um estado anormal com sistemas de detecção de ângulo de rotação de sistemas 3, pode instantaneamente especificar um sistema anormal mesmo se qualquer um dos sistemas de detecção de ângulo de rotação se torna anormal e continua Um controle de assistência por uma detecção angular altamente confiável com outros sinais de detecção de ângulo normal. Meios para resolver o problema A presente invenção se refere a um aparelho de direção elétrica que calcula um valor de comando de corrente com base em pelo menos um torque de direção, executa um controle PWM de um motor sem escovas por um inversor baseado no valor de comando de corrente, executa um controle de corrente detectando um ângulo do motor sem escova, e executa um controle de assistência de um sistema de direção, compreendendo: três sistemas de detecção de ângulo de rotação para detectar três ângulos de rotação do motor sem escova; e uma seção de diagnóstico de ângulo que compara valores absolutos de diferenças em ângulos respectivos emitidos a partir dos três sistemas de detecção de ângulo de rotação com um limite, e executa um processo por diagnosticar se os sistemas de detecção de ângulo de rotação são normais ou anormais; em que o controle de assistência é continuamente realizado utilizando ângulos de saída emitidos a partir de sistemas diagnosticados como sendo normais.
