Abstract
In complex vehicle maneuvers it is often difficult for the driver of the motor vehicle to estimate along which tract the vehicle will move and how much free space is necessary in order to avoid collision. A process is provided for monitoring the environment space in the direction of travel of the own vehicle, in which image data of the environment around the vehicle in the direction of travel of the vehicle is recorded using a camera system the three-dimensional free space required for unimpeded travel is calculated in advance in a signal processing unit and the vehicle operator is informed regarding whether or not a sufficient free space is available to him for unimpeded travel.

22. A process for monitoring the free space in the direction of travel of a vehicle, comprising
acquiring image data of the vehicle environment in the direction of travel using a camera system, additionally, on the basis of the operating parameters and dimensions of the vehicle, pre-calculating the three dimensional free space required for unimpeded travel of the vehicle in a signal processing unit, and displaying to the operator of the vehicle at least the part of the detected image data corresponding to the pre-calculated required free space, wherein the display of the image data occurs essentially as it would appear from the perspective of the operator of the vehicle directly viewing the vehicle environment in the direction of travel, wherein at least the image data associated with the three dimensional free space is subjected to a further processing, and wherein as a result of this further processing the vehicle operator is informed with regard to whether or not sufficient free space is available for unimpeded travel.

35. A device for monitoring the free space in the direction of travel of a vehicle, including:
-
a camera system for acquiring image data from the vehicle environment in the direction of travel of the vehicle, a signal processing unit, which is in communication with sensors for detecting the operating parameters of the vehicle and which includes a memory in which data is recorded regarding the dimensions of the vehicle, a display unit in communication with the signal processing unit, for display of at least that part of the image data representing the required three-dimensional free space, wherein the memory associated with the signal processing unit is so designed and arranged, that a number data sets are recorded in the memory regarding different vehicle dimensions, each of which can be specifically selected and made available to the signal processing unit, and/or the memory is provided with a means via which the at least one data set stored in memory can be changed. - View Dependent Claims (36, 37, 38, 39, 40, 41)

42. A process for monitoring the space behind a vehicle during backing-up or repositioning of the vehicle, comprising:
-
acquiring image data of the vehicle environment in the direction of travel using a camera system, additionally, on the basis of the operating parameters and dimensions of the vehicle, pre-calculating the three dimensional free space required for unimpeded travel of the vehicle in a signal processing unit, and displaying to the operator of the vehicle at least the part of the detected image data corresponding to the pre-calculated required free space, wherein the display of the image data occurs essentially as it would appear from the perspective of the operator of the vehicle directly viewing the vehicle environment in the direction of travel, wherein at least the image data associated with the three dimensional free space is subjected to a further processing, and wherein as a result of this further processing the vehicle operator is informed with regard to whether or not sufficient free space is available for unimpeded travel.
