Abstract
A method and a device for warning following vehicles in a group of several sequential vehicles, including at least a leading vehicle, a middle vehicle and a following vehicle, wherein a warning is transmitted from the middle vehicle to the following vehicle. A total distance and a total relative speed between the leading vehicle and the following vehicle are calculated based on measurements made by the middle vehicle. The total distance and total relative speed are used to determine whether a critical approach of the following vehicle to the leading vehicle is occurring, and if so, an automatic warning is transmitted from the middle vehicle to the following vehicle.

13. A method for warning a vehicle in a group of vehicles which are traveling one behind another, including at least a leading vehicle, a middle vehicle and a following vehicle, said method comprising:
-
calculating a total distance and a total relative speed between the leading vehicle and the following vehicle, based on relative speed and distance information determined by the middle vehicle; determining whether a critical approach of the following vehicle to the leading vehicle is occurring based on said total distance and total relative speed; and when a critical approach is occurring, transmitting an automatic warning from the middle vehicle to the following vehicle. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. A device for performing a method for warning a vehicle in a group of vehicles which are traveling one behind another, including at least a leading vehicle, a middle vehicle and a following vehicle, said method including calculating a total distance and a total relative speed between the leading vehicle and the following vehicle, based on relative speed and distance information determined by the middle vehicle;
- determining whether a critical approach of the following vehicle to the leading vehicle is occurring based on said total distance and total relative speed; and
when a critical approach is occurring, transmitting an automatic warning from the middle vehicle to the following vehicle;
wherein;the middle vehicle comprises at least one sensor directed to the front and at least one sensor directed to the rear, which sensors sense said front distance, and front relative speed, said rear distance and said rear relative speed. - View Dependent Claims (23, 24)
