    • An automotive device for the inspection of internal spaces having ferromagnetic surfaces includes at least two magnetic wheels (3) or caterpillars, or at least two magnetic legs for the advancement of the device along the surfaces to be inspected. According to the invention, the device includes actively powered rotating arms (1) attached to a wheel (3), caterpillar, or leg of the device. Each rotating arm (1) has a length longer than the shortest distance between the point of attachment of the rotating arm to the device and the surface. When the device is in a position, where there is magnetic contact to the surface in two or more points and the device is no longer able to advance due to the strength of the magnetic forces, the rotating arms are brought into non-magnetic contact with the surface in order to create an air gap between the surface and the magnetic wheel and thus reduce the magnetic forces. The device is thereby enabled to overcome the magnetic forces and advance the device along the surface.

    • A method is presented for compensating for combustion chamber-specific actual values of a parameter, which characterizes combustions, between a plurality of combustion chambers of an Otto engine (10) operated with homogeneous filling of the combustion chambers and homogeneous charge compression ignition, said Otto engine (10) operating with a direct fuel injection and a variable valve drive, wherein the combustion chamber-specific actual values are formed as a function of signals (S—40; S—42) of combustion chamber-specific sensors (40; 42) and wherein deviations of the combustion chamber-specific actual values from a set value are processed to manipulated variables, with which a valve lift of a gas exchange valve (28) of a combustion chamber (12) is changed. The method distinguishes itself by the fact that a characteristic (pmi_ZV), in which combustion chamber-specific charge change losses are reflected, is formed as a variable characterizing combustions and by the fact that a valve lift of an intake valve (28) of the combustion chamber (12) is changed as a manipulated variable. Independent claims relate in each case to a control unit, a computer program and a computer program product.

    • The present invention relates to a method for detecting an angular position signal representing the rotary motion of a rotating part of an internal-combustion engine. The internal-combustion engine includes at least one combustion chamber. In addition, a speed sensor of the type mentioned initially is provided, the speed sensor outputting a rotation-measurement signal representing the rotary motion of a sensing wheel connected with the rotating part. At least one pressure sensor is also provided that outputs a pressure signal representing the pressure in a combustion chamber. The method according to the present invention has the following steps: Detect the pressure signal, detect the rotation-measurement signal, calculate a correction quantity that is a function, at the least, of the detected pressure signal and rotation-measurement signal, and determine the angular position signal by linking the detected rotation-measurement signal with the correction quantity. The core of the present invention is the identification and very good compensation of the sensing wheel error by performing a joint evaluation of the rotational-speed signal and the compression chamber pressure of one or more indicated cylinders.
