Abstract

The invention relates to an assistance system for assisting a driver of a motor vehicle having a plurality of external and internal view sensors (video sources) which supply traffic-related, visual data items, an object detection unit which is connected downstream of the external and internal view sensors, an evaluation logic for evaluating the output variable of the object detection unit and having output channels whose output signals inform the driver by means of a man/machine interface. In order to propose an autonomous system which decides independently, in accordance with the detected objects, whether and how the driver is informed or which engages autonomously in the vehicle movement dynamics in order, for example, to avoid a collision, the invention provides that a decision unit (3) is provided which, when a traffic-related object or a traffic-related situation is detected by the external view sensors (11, 12) and internal view sensors (15, 16), logically combines the visual data items with the output signals, which inform the driver, from the output channels with the effect of controlling or influencing the man/machine interface (4).

Claims

1-27. -27. (canceled)

28. An assistance system for assisting a driver of a motor vehicle, comprising:

a plurality of external and internal sensors which supply traffic-related visual data items;

an object detection unit which is operably connected to the system downstream of said plural external and internal sensors;

an evaluation logic unit for evaluating the output variable of the object detection unit;

output channels of the evaluation logig unit whose output signals inform the driver by a man/machine interface; and

a decision unit which logically combines the supplied traffic-related visual data items with the output signals from the output channels when one of a traffic-related object and a traffic-related situation is detected by said plural external sensors and internal sensors, such that the man/machine interface is controlled or influenced to inform the driver of the one of the traffic-related object and the traffic-related situation.

29. The assistance system as claimed in claim 28, wherein the a plurality of external and internal sensors comprise video sources.

30. The assistance system as claimed in claim 28, wherein the decision unit is configured to generate at least one of a visual event, an acoustic event and a haptic event at the man/machine interface when the one of the traffic-related object and traffic-related situation is detected by said plural external sensors and internal sensors.

31. The assistance system as claimed in claim 30, wherein the visual event is formed by a video representation in which detected objects are highlighted by coloring whose type is dependent on a hazard potential of the detected objects.

32. The assistance system as claimed in claim 31, wherein the hazard potential is the product of the absolute distance of the detected object from the vehicle and the distance of the detected object from the predicted driving line.

33. The assistance system as claimed in claim 31, wherein the hazard potential is represented by gradation of the brightness of the coloring or by different colors.

34. The assistance system as claimed in claim 31, wherein the video representation is shown continuously on at least one of a head-up display, a combination instrument and a central console display.

35. The assistance system as claimed in claim 34, wherein graphic information is additionally represented on at least one of the head-up display, the combination instrument and the central console display.

36. The assistance system as claimed in claim 35, wherein the graphic information comprises road signs, adaptive cruise control functions, the current vehicle velocity or navigation instructions of a navigation system.

37. The assistance system as claimed in claim 31, wherein the video representation is shown continuously on a central information display.

38. The assistance system as claimed in claim 37 wherein the video representation includes a warning message output on the central information display.

39. The assistance system as claimed in claim 37, wherein a warning message is additionally output on at least one of a head-up display, a combination instrument and a central console display.

40. The assistance system as claimed in one of claim 31, wherein the video representation is shown temporarily on a central information display.

41. The assistance system as claimed in claim 40, wherein the activation of each of said plural external sensors is indicated by a control light in the combination instrument.

42. The assistance system as claimed in claim 40, wherein the video representation includes a warning message output on the central information display.

43. The assistance system as claimed in claim 40, wherein an additional warning message is output on at least one of a head-up display, a combination instrument and a central console display.

44. The assistance system as claimed in claim 28, further comprising a road profile calculator configured to determine a virtual road profile that is represented on the man/machine interface, said virtual road profile corresponding to a real road profile.

45. The assistance system as claimed in claim 28, wherein at least one of potential obstacles and hazardous objects which are located on the roadway are represented on the man/machine interface.

46. The assistance system as claimed in claim 40, wherein a size of at least one of the represented obstacles and the hazardous objects varies with distance from the vehicle.

47. The assistance system as claimed in claim 40, wherein at least one of the video representation of at least one of the detected obstacles and the hazardous objects varies as a result of a weighting as a function of a probability of a collision.

48. The assistance system as claimed in claim 42, wherein the evaluation logic unit is further configured to differentiate between relevant and irrelevant obstacles.

49. The assistance system as claimed in claim 46, wherein the evaluation logic unit is configured to classify the hazardous objects by adjustment of colors.
