The invention relates to a display device for motor vehicles and a method for control of a display device for motor vehicles, particularly motor vehicles which require an additive in addition to the fuel for operation thereof, which is used up as a function of the fuel used and further driving parameters. By means of the inventive display device, the range of the additive reservoir is displayed with relation to the range of a full fuel tank.

A device is provided for predictively detecting and avoiding motor vehicle collisions, including a control device, a sensor system for sensing obstacles in the surroundings of the vehicle, and a signal transmitter system for audibly and/or visually signaling a significant risk of collision between the vehicle and an obstacle. In order to increase the field of application of such a device, the vehicle can be a utility vehicle, the sensor system being divided into a front sensor arrangement which is arranged in the region of the front of a vehicle, and a rear sensor arrangement which is arranged in the region of the rear of a vehicle. The front sensor arrangement is connected to the control device via a data bus, while the rear sensor arrangement is connected to the control device via a power line communication.

The invention relates to a method for the predictive determination of the change in the yaw rate (ψ) of a vehicle. According to said method, the progress of the build-up of the braking pressures (p1 to p4) of the wheel brakes is monitored, and the change in the yaw rate (ψ) of the vehicle is determined in a predictive manner from the progress of the pressure build-up before the vehicle rotates around the vertical axis thereof. The inventive method allows the driving stability of a vehicle to be better regulated.

A redundant data bus system has two data buses between which at least two failsafe control devices are connected. The two data buses operate with the same data bus protocol at essentially the same transmission frequency, and safety-related control messages are transmitted in parallel via both data buses and processed in the control devices. Each control device performs a separate control task via assigned control software. Each control device has two microcomputers which operate independently of one another and which have software for both the first and the second control tasks. When one control device fails, the control task can also be performed by the other. One data interface is arranged between the two microcomputers, via which result data calculated from the safety-related control messages can be exchanged and compared with one another. Based on such comparison a decision means determines which microcomputer or control device carries out a control task.

A method for determining the geometry of a route section, using route points representing information about the route section, wherein route section data between at least three adjacent route point s are calculated, for determining a maximum possible speed for a vehicle traveling along the route section, is characterized in that a check is made to ascertain whether two adjacent route points f all below respectively predeterminable distances from one another and in the affirmative route section data through the se route points are calculated as a) straight line if the route points are arranged in a straight strip of predeterminable width, or b) arc of a circle if the route points are arranged in a constantly curved strip of predeterminable width and the tangent to the, in the direction of travel, first one of the route points is essentially located on a direction vector of the vehicle, or c) clothoid if the route points are arranged in a progressively curved strip of predeterminable width, wherein the geometry of the route section in the region of said route points is in each case determined in the form of the calculated route section data.

A system and a method for directionally stabilizing a vehicle with the aid of a steering system used for influencing a steering angle of the vehicle steered wheels and a stabilizing system which controls the steering system for increasing the vehicle directional stability is provided. The stabilizing system is characterized in that the stabilizing system controls the steering system according to the lateral force factor of at least one steered wheel for defining the steering angle stabilizing the vehicle, wherein the stabilizing system adjusts the slip angle of the steered wheels in such a way that the lateral force factor does not substantially exceed the maximum range thereof.
