Abstract: To assist the driver of a vehicle in driving the vehicle in an improved, environmentally conscious way, a first consumption profile of a first predetermined instantaneous consumption and/or pollutant emissions over a predefined route is displayed on the display device, and at the same time a second consumption profile of an actual instantaneous consumption over a route section of the predefined route that has been traveled along by the vehicle, is displayed on the display device. Furthermore, it is proposed that a first pollutant emission profile of a first predetermined instantaneous amount of pollutant emissions over the predefined route is displayed on the display device and at the same time a second pollutant emission profile of an actual instantaneous amount of pollutant emissions over the route section traveled along by the vehicle, of the predefined route is displayed on the display device.

Abstract: A method for controlling the outputting of messages in an information system of a motor vehicle, the messages being assigned priorities, there is provision for the sequence, the time and, if appropriate, also the method (visual, audible, tactile) of the outputting of the messages to depend on the priority of the respective message and on criteria which are formed from information received from the information system.

Abstract: The invention relates to an arrangement for cooling a component in a vehicle with a device for providing cool air, with at least one air supply device for feeding the cool air into a passenger compartment of the vehicle, and with a first air-guiding element which branches off from the air supply device before it reaches the passenger compartment, conducts part of the cool air away from the air supply device and guides it to the component to be cooled. According to the invention, an air suction device conducts air away from the component.

Abstract: An arrangement in a motor vehicle includes a support structure which is made of magnesium or of a magnesium alloy and includes at least one solid portion. Further, the arrangement includes an electronic component which is supported or held by the support structure, and a connection arrangement having a connection element which is at a prespecified electrical potential. At least one self-tapping screw is self-tapped into the solid portion of the support structure and thereby mechanically connects the support structure to the connection arrangement.

Abstract: The invention relates to an arrangement of groups of electronic components in the cockpit of a motor vehicle having a first group of electronic components for controlling a first vehicle function mounted on a first printed circuit board (9). According to the invention the printed circuit board (9) is fixed directly onto a support and/or a front panel (1) of the cockpit.

Abstract: The invention relates to a display unit (1) having a display panel (2) which displays information from an electronic appliance in a vehicle and which is arranged between a first and a second viewer and whose display panel (2) can be oriented either to the first or to the second viewer. In line with the invention, the display unit (1) is provided with a swivel device (4, 12) for automatic orientation. The swivel device (4, 12) is in turn connected to a user identification device which identifies whether the first or the second viewer is currently using the electronic appliance. The swivel device (4, 12) orients the display panel (2) automatically to the viewer identified as the user.

Abstract: In an instrument panel (18) for a motor vehicle having a carrier (19), electrical leads (24) are stretched between contact pins (22, 23) of an electronic component (21) and/or a plug part (20). The contact pins (22, 23) are pressed into the carrier (19). This makes mounting the electrical leads (24) on the instrument panel (18) particularly easy.

Abstract: A heating sheet bundle to be mounted tangentially or radially in trapezoidally segmented cells of heating surface carriers of regenerative heat exchangers with stationary or revolving storage masses is composed of a plurality of profiled sheets which are stacked on top of each other and are held together so as to form passage ducts therebetween. On at least two oppositely located sides of the bundle, at least the two outer profiled sheets are constructed as a pair of sheets connected in a dimensionally stable, sandwich-like manner. One of the profiled sheets of the pair of profiled sheets is undulated and the other of the profiled sheets of the pair of profiled sheets is corrugated, wherein the rolling depth of the undulated sheet is greater than the rolling depth of the corrugated sheet.
