The invention relates to a suspension system (1), comprising a spring support (3) for a vehicle suspension spring (5), a spring plate (7) supporting the vehicle suspension spring (5) being arbitrarily adjustable in terms of its position by supplying it with a pressure medium (47-63) in order to control the level of a vehicle body, the spring support (3) being designed as a hydro-pneumatic spring (45) the hydraulic volume of which relative to a pneumatic memory element (43) can also be adjusted.


The invention relates to a selector lever reset device (100) for a vehicle gearbox. The selector lever reset device (100) comprises a selector lever (105) for selecting a gearbox setting of the vehicle gearbox and a lever guide apparatus (110) which has at least one slide element (115) and a locking slide (120). The slide element (115) is movably arranged in the lever guide apparatus (110) along a slide axis (125) and has a latch contour (145). The selector lever (105) is or can be mechanically coupled to the slide element (115) in order to be moved along the slide axis (125) between a rest position (130) and an actuating position (135). The locking slide (120) is movably arranged in the lever guide apparatus (110) along a slide axis (140) deviating from the slide axis (125) at least between a rest position and a release position and has at least one latching element (150). The latching element (150) latches in place with the latching contour (145) when the selector lever (105) is in the actuating position (135) and the locking slide (120) is in the latching position. In the reverse, the latching element (150) releases the latching contour (145) when the locking slide (120) is in the release position.


The invention relates to a method for regulating a DC-to-DC converter of a motor vehicle electrical system, comprising a first converter (102) and a second converter (104) connected downstream of the first converter. The first converter (102) is designed to convert an input signal (112) of the DC-to-DC converter into an intermediate circuit signal (114) on the basis of an adjustable first conversion ratio of the first converter (102), and the second converter (104) is designed to convert the intermediate circuit signal (114) into an output signal (116) of the DC-to-DC converter on the basis of a second adjustable conversion ratio of the second converter (104). The method has a step of determining a first control signal (232) in order to adjust the first conversion ratio of the first converter (102) using the output signal (116) of the DC-to-DC converter in order to regulate the intermediate circuit signal (114) at a target value (345), which depends on the output signal (116), for the intermediate circuit signal (114).


The invention relates to a method for controlling a hydraulic-medium supply system of an automatic transmission of a vehicle, wherein the hydraulic-medium supply system is supplied with hydraulic medium at least by an engine-driven hydraulic pump (FZP-Pu) and by a gear-set-driven hydraulic pump (RS-Pu). According to the invention, a cooling valve of the hydraulic-medium supply system for supplying hydraulic medium is controlled in dependence on sensed vehicle parameters in order to set an adapted delivery-rate distribution for the hydraulic pumps (FZP-Pu, RS-Pu).
