Process and device for detecting and monitoring a number of preceding vehicles
First Claim
1. A process for detecting and monitoring a number of vehicles (A through C) preceding a monitoring vehicle (E), comprising:
- subdividing the environment preceding the monitoring vehicle into at least one near zone (ZII) and at least one distant zone (ZI), determining for the preceding vehicles (A through C) respectively the lane (S1 through S3), speed (VA through VC) and distance from the monitoring vehicle (E), determining on the basis of the respectively determined lane (S1 through S3), speed (VA through VC) and distance information for the preceding vehicles (A through C) their positions with respect to the near zone (ZII) or the distant zone (ZI), and adjusting the actual speed (VE actual) of the monitoring vehicle (E) on the basis of the respectively determined speed (VA through VC) and position of the preceding vehicles (A through C).

Abstract
For substantial relieving the driver of a vehicle with respect to the monitoring of the preceding environment as well as the evaluation of distances and speeds of multiple preceding vehicles, there is provided in accordance with the invention a process for detecting and monitoring a number of vehicles (A through C) preceding one'"'"'s own vehicle (E), which process divides the preceding environment into at least a near zone (ZII) and at least one distant zone (ZI), wherein for the preceding vehicles (A through C) respectively their lane (S1 through S3), speed (VA through VC) and/or distance to the monitoring vehicle (E) are determined, and on the basis of the respective determined lane (S1 through S3), speed (VA through VC) and/or distance for the preceding vehicles (A through C) their position with respect to the near zone (ZII) or the distant zone (ZI) are determined, wherein on the basis of the respective determined speeds (VA through VC) and/or positions of the preceding vehicles (A through C) the actual speed (VE actual) of the monitoring vehicle (E) is adjusted.
