Abstract: A control bus (165) permits the transmission of a message (205) of a predetermined message length. A method (300) for transmitting pieces of information on the control bus (165) includes transmitting a message (205). The message includes a first field (210) and a second field (215). The first field (210) contains a variable reference to a type of information, and the second field (215) contains a piece of information of the type of information referred to in the first field (210).

Abstract: An oil pump drive device (1) may include a housing (G), an oil pump drive shaft (AN), an electric motor, and a planetary gear set (RS). The planetary gear set (RS) may be supported by the housing (G) and have a first element (E1) connected to a rotor (R) of the electric motor, a second element (E2) connected to the oil pump drive shaft (AN), and a third element (E3) drivable by a drive source located outside the oil pump drive device (1). A first bearing (L1) may be supported on the housing (G) and may support at least one of the elements (E1, E2, E3) of the planetary gear set (RS) in a radial direction. The stator (S) of the electric motor is at least partially surrounded by a plastic mass (K), where the stator (S) is attached to the housing (G) via the plastic mass (K).

Abstract: A component of a transmission device, which rotates around a central axis and is adjustable in an axial direction, includes with an encoder contour on the circumference of the component that interacts with a sensor device. The encoder contour features at least one area provided for calculating the axial position of the component, whereas a surface of the first area is designed with a varying radial extension along the axial direction relative to the central axis. The encoder contour has second areas for calculating the rotational speed of the component, whereas a slope of a radial surface of the second areas in the axial direction is differentiated from a slope of the surface of the first areas in the axial direction. In the circumferential direction of the component, the encoder contour is designed alternately with first areas and second areas.

Abstract: A component (2), in particular a shifting element of a transmission device, which rotates around a central axis (14) and is adjustable in an axial direction (y), with an encoder contour (5) revolving on the circumference of the component (2) and provided for interacting with a sensor device (4), is described. The encoder contour (5) features at least one area (7) provided for calculating the position of the component (2) in an axial direction (y), whereas a surface (11) of the first range (7) in an axial direction (y) is designed with a varying radial extension in respect of the central axis (14). The encoder contour (5) features several second areas (8) for calculating the rotational speed of the component (2), whereas a slope of a radial extension of a surface (20) of the second areas (8) in the axial direction (y) of the component (2) is differentiated from a slope of a radial extension of the surface (11) of the first areas (7) in the axial direction (y) of the component (2).
