Abstract

An apparatus is described for assisting driving of a vehicle having at least two driver assistance systems and having an output device or element for communicating information items of at least one of the driver assistance systems to a driver of the vehicle. To relieve the strain on the driver, a control device or element, configured as an information coordinator and connected at its input side to the driver assistance systems and at its output side to the output device is provided for controlling information items of the driver assistance systems to be communicated to the driver.

Claims

1-13. -13. (canceled)

14. An apparatus for assisting driving of a vehicle having at least two driver assistance systems and having an output device for communicating information items of at least one of the driver assistance systems to a driver of the vehicle, the apparatus comprising:

a control device, configured as an information coordinator and connected at its input side to the driver assistance systems and at its output side to the output device, the control device adapted to control information items of the driver assistance systems to be communicated to the driver.

15. The apparatus as recited in claim 14, wherein the control device is adapted to combine a first information item arriving from a first of the driver assistance systems and a second information item arriving from a second of the driver assistance systems to produce an overall information item and to forward the overall information item to the output device.

16. The apparatus as recited in claim 14, wherein the control device is connected at its input side to at least one of:

i) at least one driver information system, and ii) directly to at least one vehicle sensor.

17. The apparatus as recited in claim 14, wherein the control device includes a decision element adapted to indicate information items of at least the driver assistance systems that are to be forwarded to the output device.

18. The apparatus as recited in claim 14, wherein the control device includes a prediction element for indicating information items of at least the driver assistance systems that are to be expected.

19. The apparatus as recited in claim 18, wherein the control device has a memory containing driving situations that are to be expected, and the memory is connected upstream of the prediction element.

20. The apparatus as recited in claim 14, wherein the output device includes at least one of an optical output element, an acoustic output element, and a haptic output element.

21. The apparatus as recited in claim 20, wherein the output device includes at least two output elements, outputs of which are each perceptible by a different human sense.

22. The apparatus as recited in claim 20, wherein an output coordinator adapted to control information items forwarded by the control device to the output device is disposed between the control device and the output device.

23. The apparatus as recited in claim 21, wherein the output device has, connected upstream of the output elements, an output coordinator adapted to control information items forwarded by the control device to the output device.

24. The apparatus as recited in claim 14, wherein the driver assistance systems include at least one of an adaptive cruise control driver assistance system, a lane departure warning driver assistance system, and a lane change assist driver assistance system.

25. A method for assisting driving of a vehicle having at least two driver assistance systems, comprising:

receiving, by a control device, an information item of one of the driver assistance systems which is to be communicated to the driver;

simultaneously receiving an indication by a prediction device of an information item of another of the driver assistance systems which is to be expected with a predetermined probability;

performing, by the control device, an information combination based on the information item of one of the driver assistance systems and the information item of the other of the driver assistance systems, to produce an overall information item; and

forwarding the overall information item to an output device.

27. The method as recited in claim 25, further comprising:

associating, by the control device, information items of the driver assistance systems arriving in the control device with a driving situation from among a plurality of driving situations that are to be expected and which are stored in a memory, the associated driving situation being taken into consideration for the information combination.

26. A method for assisting driving of a vehicle having at least two driver assistance systems, comprising:

receiving, by a control device, an information item of one of the driver assistance systems which is to be communicated to a driver;

simultaneously receiving an indication of an information item of another of the driver assistance systems which is to be expected with a predetermined probability;

performing, by the control device, an information combination based on the information item of one of the driver assistance systems and the information item of the other of the driver assistance systems, to produce an overall information item; and

forwarding the overall information item to an output device.
