Abstract
A device for detecting a momentary distance between a motor vehicle and an obstacle is provided. The device includes distance sensors and a control unit that is designed to calculate a driving path to be traveled through in future by the motor vehicle. The driving path is calculated using dynamic vehicle data and the control unit is designed to differentiate between relevant obstacles which are located within the driving path, and irrelevant obstacles which are located outside the driving path. A method for detecting a momentary distance between a motor vehicle and an obstacle is also provided.

17. A device for detecting a momentary distance between a motor vehicle and an obstacle, the device comprising:
-
distance sensors; and
a control unit, wherein the control unit is arranged to calculate a driving path to be traveled through in future by the motor vehicle, using static and dynamic vehicle data, and the control unit is arranged to differentiate between relevant obstacles which are located within the driving path and irrelevant obstacles which are located outside the driving path, and wherein the distance sensors each have a variable detection area, the control unit is arranged to adapt the range of the detection areas of the distance sensors to lateral boundaries of the driving path, and the distance sensors whose detection area is located completely in the driving path are actuated by the control unit in such a way that they operate with maximum range (Rmax). - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. A method for detecting a momentary distance between a motor vehicle and an obstacle, the vehicle having distance sensors and having a control unit, the method comprising the acts of:
-
calculating by the control unit a driving path to be traveled through by the motor vehicle using static and dynamic vehicle data;
differentiating relevant obstacles within the driving path from irrelevant obstacles which are located outside the driving path; and
controlling, by the control unit, the range of the detection areas of the individual distance sensors in such a way that distance sensors whose distance areas are located completely on the driving path operate with maximum range while other distance sensors are actuated outside their maximum range so that their detection area is located essentially within the driving path. - View Dependent Claims (25, 26, 27, 28, 29)
