Abstract: A navigation method includes selecting a route from a multiplicity of routes, which connect a departure point for a navigation to a destination for the navigation. The route includes at least one route segment. The at least one route segment for the route is selected from a multiplicity of road sections. The road sections are each assigned at least one property, which characterizes a driving experience. A metric is evaluated in accordance with the at least one property of a respective road section of the road sections. The route whose road sections maximize the metric as route segments for the route is selected.

Abstract: The wheel for a motor vehicle is composed essentially of a fiber composite material, wherein the spokes of the wheel are each formed with a longitudinally extending cavity and said cavity is fluidically connected to a rim well or to a tire-rim space formed by the rim well and a mounted tire via an air passage opening, with the result that both monitoring of the hollow spokes for damage and in the case of tire damage is possible by a tire pressure monitoring device arranged in the wheel.

Abstract: A steering wheel has at least one shift paddle which is coupled to the steering wheel in such a manner that the shift paddle is movable relative to the steering wheel in order in a contactless manner to trigger a shifting operation. In order to improve the ease of operation when actuating the shift paddle on the steering wheel, the steering wheel is distinguished by a slotted guide mechanism by which a shifting sensation is generated during movement of the shift paddle.

Said invention is characterized by the following features: a drive which has an output shaft; a machine which has a drive shaft; a converter (3) which is connected between drive and machine and can be filled and emptied; having a toothed clutch (4) which can be engaged and disengaged and is connected in parallel with the converter (3); one half (4.1) is firmly connected to the output shaft of the drive so as to rotate with it; the other half (4.2) of the clutch is firmly connected to the drive shaft of the machine so as to rotate with it.

Abstract: A hydrodynamic converter is provided having a pump wheel, which is flowed through in operation from the inside to the outside; a turbine wheel, which is flowed through in operation from the outside to the inside; guide blades between the pump wheel and the turbine wheel; and guide blades between the turbine wheel and the pump wheel. The converter can have a speed ratio of between the speed nT of the turbine wheel and the speed nP of the pump wheel of between 1.2 and 4 at approximately even or falling ? progress. The converter can also have different speed ratios between pump and turbine, which can be realized with the ratio R/r equal to or larger than 1.

Abstract: Coverings suitable for a steering wheel of a motor vehicle are inserted into at least two approximately horizontally oriented spokes connected with a steering wheel ring adjacent to the steering wheel ring. The coverings are constructed for the accommodation of switches. On one side, each covering leads away from the steering wheel ring and, on the other side, each covering adjoins a trim plate of the steering wheel. In order to provided the steering wheel with an advantageous design, the coverings are constructed as modules which, depending on the equipment of the motor vehicle, have function areas provided with areas without switches and/or with switches.
