In a method for chassis control of a motor vehicle which has at least one wheel suspension, a vehicle body, and a shock absorber having a rebound stage, whose stiffness is adjustable, and a compression stage, whose stiffness is adjustable, the stiffness of the compression stage is changed for a compressive load of the shock absorber generated by a specific vehicle body movement, and the stiffness of the rebound stage is additionally changed for a subsequently following tensile load of the shock absorber generated by the specific vehicle body movement, or the stiffness of the rebound stage is changed for a tensile load of the shock absorber generated by a specific vehicle body movement, and the stiffness of the compression stage is additionally changed for a subsequently following compressive load of the shock absorber generated by the specific vehicle body movement.

In a method for setting a wheel torque in a vehicle, a setpoint value for a slip-adhesion coefficient gradient for one wheel of one vehicle axle is ascertained, and the wheel torque is set in such a way that the actual value of the gradient is approximated to the setpoint value.

Method for setting a wheel torque in a vehicle

A system is provided for providing travel time information for a plurality of positions on an electronic map. The system provides map data including information on road segments, determines a plurality of road segment travel times based on the map data, selects a plurality of positions for which travel time information is to provided, determines a travel time for each of these positions in dependence on the road segment travel times, and displays an optical indicator for the travel times on an electronic map.

Travel time information system

A playback device and a storage medium for storing audio data make it possible to increase the audio data volume that may be stored on such a storage medium without increasing the data density. To this end, the audio data compressed according to at least one compression method is stored on the storage medium. The playback device includes a drive for storage media and a scanning device for audio data recorded on a storage medium inserted into the drive. The playback device furthermore includes a control that checks whether the data read is compressed. The playback device furthermore includes a decompression device that performs decompression of the audio data if the audio data is compressed.

Playback device and storage medium for selective storage of data as a function of data compression method

To facilitate the operation of an in-vehicle navigation system and to shorten the time required for the otherwise time-consuming entering of the destination by crosshairs by reducing the operating steps required, a general map and an enlarged portion of the general map are displayed simultaneously on a screen. A navigation computer calculates the routes. Map data from general maps and detail maps are stored in a memory. A main computer calculates the portion selectable for example by crosshairs and shown on an enlarged scale, from the data stored in the memory. The general map and the enlarged portion can be moved synchronously with one another on the screen by a graphic control unit.

Motor vehicle navigation system with enhanced map selection

A navigation unit, especially for vehicles, with a data bus, a data memory on which a plurality of map information items and navigation data are stored, with a navigation computer, connected to the data bus, for route planning, with a data processing unit, connected to the data bus, for processing the data into picture information, the data processing unit containing a picture memory for storing the picture information, with a monitor, connected to the data processing unit, on which the picture information can be displayed, with a communication block with a control unit for entering the start location, intermediate destination, and/or final destination of a trip, such that the data processing unit contains a map memory for storing road map information.
