  • Patent number: 11572059
    Abstract: A method to detect whether combustion is taking place in an internal combustion engine of a hybrid vehicle during operation of the hybrid vehicle, whereby a decoupler is provided between the internal combustion engine and an electric machine that serves to power the hybrid vehicle, comprising opening the decoupler between the internal combustion engine and the electric machine, receiving a speed signal when the decoupler is open, said signal indicating a rotational speed of the internal combustion engine when the decoupler is open, and determining, on the basis of the speed signal when the decoupler is open, whether combustion is taking place in the internal combustion engine. The present invention also relates to a control device to carry out the method according to the invention.

  • Publication number: 20200173503
    Abstract: The present invention relates to a method to detect whether combustion is taking place in an internal combustion engine (10) of a hybrid vehicle during operation of the hybrid vehicle, whereby a decoupler (13) is provided between the internal combustion engine (10) and an electric machine (12) that serves to power the hybrid vehicle. The method comprises opening (31) the decoupler between the internal combustion engine (10) and the electric machine (12), receiving (32) a speed signal when the decoupler is open (13), said signal indicating a rotational speed of the internal combustion engine (10) when the decoupler (13) is open, and determining (33, 38), on the basis of the speed signal when the decoupler (13) is open, whether combustion is taking place in the internal combustion engine (10). The present invention also relates to a control device to carry out the method according to the invention.

  • Patent number: 10640107
    Abstract: A method for detecting a combustion process of an internal combustion engine of a hybrid vehicle includes the steps of acquiring a rotational speed signal representing a rotational speed of the crankshaft, acquiring a crankshaft angle signal representing a crankshaft angle of the crankshaft, and determining, based on the rotational speed signal and the crankshaft angle signal, whether a combustion occurs in the internal combustion engine. A control device for detecting a combustion process of an internal combustion engine of a hybrid vehicle is also provided.
