    摘要： A method for open-loop control of a drive device for assisting a vehicle at least intermittently operable by muscle power is provided. The vehicle includes a driving wheel drivable by drive force provided from the drive device, and a crank apparatus rotatable by a rider of the vehicle. The method includes: (S1) querying a predetermined operating mode of the drive device specifiable by the rider of the vehicle; (S2) detecting a rotational speed of the driving wheel; (S3) detecting a rotational speed of the crank apparatus; (S4) determining a synchronous operation with respect to the rotational speed of the driving wheel and the rotational speed of the crank apparatus based on a transmission ratio between the crank apparatus and the driving wheel; and (S6) controlling the drive device with a predefined drive power regardless of a muscle power introduced into a crank apparatus when the predetermined operating mode is present and the synchronous operation is present.

    摘要： A drive unit has a first electric machine with a first rotor mounted to rotate about a rotation axis. A first stator is coaxially arranged and has a stator core lamination packet with a first coil end forming a first switching side and a second coil end forming a first counter-switching side. A second electric machine is mounted axially close to the first electric machine and has a rotatably mounted second rotor that extends in the axial direction around the rotation axis. A second stator is mounted coaxially with the second rotor and has a second stator core lamination packet with second stator coils having a third coil end forming a second counter-switching side and a fourth coil end forming a second switching side. A housing accommodates the first and second machines, where the first counter-switching side and the second counter-switching side face one another in the axial direction.

    摘要： A vehicle transmission (1) which comprises a lubrication system and a connection for attaching a power take-off module (9) to the vehicle transmission. The lubrication system is designed to lubricate the vehicle transmission and the power take-off module (9). The lubrication system has a pressure feed (13) and a lubricant line (12) fed with lubricant from the pressure feed. By way of a first section (12A), the lubricant line (12) leads to at least one lubrication point of the vehicle transmission and, by way of a second section (12B), to a lubricant tapping point (15) of the vehicle transmission for the power take-off module. A throttle (17) and a first valve (18), connected parallel to the throttle, are arranged in the second section (12B). The first valve (18) is designed to open toward the lubricant tapping point if the lubricant pressure rises to a first pressure level.

    摘要： A method for assigning an electric vehicle (20, 22, 24) to a user includes: receiving a request from the user via a receiving device stating that the user needs an electric vehicle (20, 22, 24), the request including usage information regarding the planned use of the electric vehicle (20, 22, 24); determining a target state of charge of a battery (22) of at least one available electric vehicle (20, 22, 24) depending on the usage information; determining an actual state of charge of the battery (22) of the electric vehicle (20, 22, 24); and assigning the electric vehicle (20, 22, 24) to the user when the determined actual state of charge is greater than or equal to the determined target state of charge.

    摘要： The invention relates to a stator (IO) in an electric machine (I) with a laminated core (II) formed in an annular fashion about a central axis (A), on which core stator coils (16) with coil ends (16a, b) are arranged by means of formers (12a, 12b). The stator (IO) comprises wiring device (20), on which a plurality of mutually isolated connecting conductors (22-26) with coil connection areas (22a-26a) are present for connecting the stator coils (16). The wiring device (20) is joined on the stator in an axial joining direction to the stator coils (16) and is secured by axial connection means (30a, b) to the formers (12a), thus forming a plurality of axial connections (32a, b). According to the invention, to increase the stiffness of the stator (IO), radial supporting means (40, 41) are additionally formed on the wiring device (20) to interact with the formers (12a), said means being designed to be functionally independent of the axial connection means (30a, b).
