Abstract

Method (400) and control unit (210) for adjusting an inter vehicular distance (130) between vehicles (100a, 100b, 100c) in a platoon (110). The control unit (210) is configured to: obtain a geographical position for a vehicle (100a, 100b, 100c) in the platoon (110); determine a zone (200a) wherein the obtained geographical position is situated; determine an inter vehicular minimum distance limit,associated with the determined zone (200a); and adjust the inter vehicular distance (130) between the vehicles (100a, 100b, 100c) in the platoon (110) into the determined inter vehicular minimum distance limit by sending a control signal to the vehicle (100a, 100b, 100c) in the platoon (110).

Description

technical field [0001] A control unit, a method in a control unit and a system are disclosed herein. More specifically, a method, a control unit and a system for adjusting the inter-vehicle distance between vehicles in a platoon are provided. Background technique [0002] Grouping vehicles into platoons is an emerging technology that can reduce fuel consumption and increase road capacity. Many vehicles (eg 2-25 or more) can be organized in a platoon or convoy where the vehicles travel in coordination with each other with only a small distance between them, eg a few decimeters or meters, eg up to 50-100 metres. This reduces air resistance, which is important for reducing energy consumption, especially for heavy vehicles such as trucks, buses and vans or other vehicles with a large frontal area. In principle, it can be said that the shorter the distance between vehicles, the lower the air resistance becomes, which reduces the energy consumption of the platoon of vehicles. M...
