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.

A method for detecting glow ignition of a fuel-air mixture in a combustion chamber of an internal combustion engine having at least one first cylinder and at least one second cylinder, the at least one first and second cylinders being connected by a crankshaft, according to which method partial segment times of the at least one first cylinder are measured. The method is characterized in that partial segment times of the at least one second cylinder are measured and a reference characteristic for the glow ignition is formed by a comparison of partial segment times of the at least one first cylinder with partial segment times of the at least one second cylinder and subsequently a signal is generated for the detection of the glow ignition on the basis of the comparison.

A method for recognizing irregular combustion in an internal combustion engine includes supplying fuel directly to a combustion chamber of a cylinder of the internal combustion engine using an injector. The injector is connected to a fuel supply line that includes a pressure sensor configured to measure pressure in the fuel supply line. The pressure in the fuel supply line is measured during the supply of fuel into the combustion chamber. It is then ascertaining whether irregular combustion is occurring based on the measured pressure in the fuel supply line.
