Abstract

o objeto da presente invenção é de proporcionar um método de controle e uma unidade de controle de um aparelho de direção assistida elétrica que simplifica um cálculo de uma transformação a partir de um valor de comando de duas fases para um valor de comando de três fases realizado no caso de dirigir e controlar um motor montado no aparelho de direção elétrica, reduz a carga do cálculo e permite a instalação em um microcomputador. um método de controle compreende uma etapa de transformação de transformar um valor de comando de duas fases calculado a partir do valor do comando atual em um valor de comando trifásico; a etapa de transformação separa uma região de um vetor consistindo do sinal de comando de duas fases em seis setores, e transforma o sinal de comando de duas fases para o valor de comando de três fases de acordo com um método de cálculo é predefinida em cada setor e é simplificado; e o aparelho de direção elétrica aciona o motor de acordo com o valor do comando trifásico. [figura designada] fig. 10.
