Abstract

1/1 resumo “dispositivo e método para controle de uma propulsão de veículo motor” a invenção refere-se a um método, um dispositivo e um programa de computador para controle de uma propulsão de veículos a motor em que um torque da embreagem (req. t) é exigido por um motorista pela ativação de um pedal acelerador, o grau de fechamento (g) do atuador de embreagem do veiculo é controlado por retorno com base em um torque de motor monitorado e há pelo menos um consumidor adicional (290) de potência do motor, além da dita propulsão. o método compreende as etapas de detecção (s410) ativação do dito pelo menos um consumidor adicional, quando tal ativação é detectada, mudando (s420) dito controle de retorno para o controle aberto através do qual o grau de fechamento (g) do atuador de embreagem de veículos é baseado em uma relação pré-determinada entre dito grau de fechamento (g) e o torque da embreagem (req t), cujo torque de embreagem (req. t) é exigido pelo motorista por uma ativação de um pedal acelerador.
