Abstract: A lighting device for vehicles with a first lighting unit having a light source and a light beam surface for emitting light and with a second lighting unit containing a light source and a flat light guide having opposite flat sides and narrow sides connecting the same for backlighting the first lighting unit. The flat light guide of the second lighting unit has a backlighting section and a linear light section. The backlighting section is arranged behind the first lighting unit and a front flat side of the flat light guide in the backlighting section serves as a light decoupling surface for the light decoupling of a first part of the light coupled into the flat light guide. The linear light section is at least partially arranged next to the first lighting unit. A narrow side of the flat light guide serves as a light decoupling line.

Abstract: A lighting device for vehicles is provided, having a flat light guide containing two flat sides facing each other, one light input coupling surface for the entry of light at a light input coupling side of the flat light guide, one light output coupling surface for the output of light input at the light input coupling surface with the light output coupling surface arranged at one light output coupling side of the flat light guide. A specified light distribution (L) is thereby generated. The flat light guide further includes one narrow lateral surface connecting the flat sides with each other and extending from one lateral border of the light output coupling side, one collection surface adjacent to the light input coupling surface shaped in such a manner that a partial light beam of the entering light striking the collection surface is reflected in total towards the light output coupling surface without the partial light beam striking the narrow lateral surface.

Abstract: A tail light with at least one light source and with a light guide body into which light generated by the light source can be coupled and out of which back-up light can be coupled, and light for illuminating the ground region can be decoupled. The light guide body has a light entry area through which light from the light source can be coupled into the light guide body. The light guide body has at least a first light exit area for the back-up light and a second light exit area for the light for illuminating the ground region, wherein the first and the second light exit areas may overlap. The light guide body has a first reflection surface at which a portion of the coupled-in light can be deflected in the direction of at least one of the light exit areas.

Abstract: A method for determining the ignition angle is provided, in which modifications of manipulated variables which have an influence on the knock limit, and therefore on the optimum ignition angle as well, are dynamically taken into account. To this end, a base ignition angle is first determined, based on the instantaneous engine speed and load. As part of a downstream knock control, a first ignition angle adjustment in the retard direction is determined when knocking has been detected. As part of a knock limit control, a second ignition angle adjustment is also determined when at least one manipulated variable influencing the knock limit changes, with the type of the second ignition angle adjustment, i.e., advancing or retarding, depending on the manipulated variable and its modification.

Abstract: This invention is based on a method for monitoring a cooling fluid circuit (16) of an internal combustion engine (10), with at least one heat exchanger (18, 22), a regulating valve (26), a cooling fluid pump (32), and an electronic control unit (76). The invention proposes that the control unit (76) predetermine a permissible upper and lower deviation of a reference parameter from a desired value, based on operating parameters of the internal combustion engine (10) and with the aid of deviation characteristic fields (56, 58), and that it compare these permissible upper and lower deviations to a difference between a desired value and an actual value of the reference parameter, wherein the actual value is determined based on parameters of the volumetric flow of the cooling fluid, possibly with the aid of characteristic fields (42, 46, 74).
