Method and control apparatus for recuperating energy in a hybrid vehicle
A method and apparatus for recuperating energy in a hybrid vehicle, having an internal combustion engine an electrical machine, and on-board electrical system with an energy store that can be charged with electrical energy during a recuperation operation. A recuperation power for a recuperation operation of the electrical machine is set to a first value that allows a recuperation operation with a maximum generator capacity of the electrical machine if an actual energy level of the energy store is lower than or equal to a threshold value. However, the recuperation power for a recuperation operation is set to a second value lower than the first value and allows a recuperation operation with a reduced generator capacity of the electrical machine if the actual energy level of the energy store is greater than the threshold value.

Arrangement for determining a revolution rate and direction of rotation of a rotating component
A sensor device for contactlessly determining a revolution rate and a direction of rotation of a component that rotates during operation of the component, the component having, on at least one peripheral region, a circumferential structure of web-shaped or tooth-shaped radial protrusions and interposed grooves or tooth gaps includes: a threaded segment configured to positionally fix an arrangement of the sensor device so that the circumferential structure of the component is movable past the sensor device; a magnetic field generating device; and a magnetic field detecting device having at least three magnetic field sensors that are not arranged in alignment along a line. A distance between the magnetic field sensors that are the farthest apart from each other is less than or equal to a width of the grooves or tooth gaps of the component.
