Embodiment Construction

[0035] according to figure 1 A convoy 100 or train of three vehicles 1 , 2 , 3 is shown, the vehicles 1 , 2 , 3 moving one behind the other on the lane 4 . The vehicle 1 driving ahead is referred to below as the lead vehicle X of the convoy 100 and the following vehicles 2 and 3 as the following vehicles Y, although more than two following vehicles Y may also be provided. The actual distance D12Ist, D23Ist between the individual vehicles 1, 2, 3 is adjusted to the predetermined target distance D12Soll, D23Soll when there is a platooning pattern P as follows, that is, between the individual vehicles 1, 2, 3 of the fleet 100 Air resistance and area consumption between get optimized.

[0036] To achieve this, the actual distance D12Ist, D23Ist is adjusted automatically by the platoon control system 5 installed in each of the vehicles 1, 2, 3 respectively. The adjustment of the actual distances D12Ist, D23Ist takes place via the distance control system 9 in the respective foll...

Abstract

The invention relates to a method for setting a vehicle deceleration (a1, a2, a3) of a vehicle (1, 2, 3) driving in a platoon (100), wherein the vehicle (1, 2, 3) is a guide vehicle (X) or a followingvehicle (Y) driving indirectly or directly thereafter, wherein in the event of a platoon mode, a predefined target distance (D12Soll, D23Soll) is set - between the vehicle (1) as guide vehicle (X) and the following vehicle (Y) driving directly thereafter, or - between the vehicle (2, 3) as following vehicle (Y) and the guide vehicle (X) driving directly in front thereof and at least one further following vehicle (Y) driving directly behind the vehicle (2, 3). According to the invention, the vehicle deceleration (a1, a2, a3) of the vehicle (1, 2, 3) as the guide vehicle (X) or following vehicle (Y) is limited to a limit deceleration if a limiting criterion is met.

Description

technical field [0001] The invention relates to a method for adjusting the vehicle deceleration of vehicles in a convoy, in particular commercial vehicles, a platoon control system for carrying out the method, and a vehicle with such a platoon control system. Background technique [0002] It is known that a plurality of vehicles can be moved in coordination with one another at short intervals one behind the other on a lane in order to save fuel by reducing air resistance. For this purpose, the current general safety distance between the individual vehicles of the convoy can be kept below when the vehicles coordinate with one another, for example by wireless communication. The individual vehicles of the convoy can be coordinated via the platooning control systems installed in each vehicle, wherein the platooning control systems in the respective vehicles can communicate with each other via wireless communication and can exchange geometric and / or travel information, for exampl...
