Problems solved by technology

However, since the gaps between vehicles are relatively short in formations based on V2V communication, it can lead to dangerous situations
Without such communication, it may be difficult to cope with such a short distance
[0012] Therefore, known formation strategies still have room for improvement

Embodiment Construction

[0069] figure 1 Vehicles referred to herein as a lead vehicle 1 and following vehicles 2, 3 are shown. In this example, vehicles 1, 2, 3 are trucks with semi-trailers. However, the invention is equally applicable to other types of vehicles, such as cars, buses and dump trucks.

[0070]Each of the vehicles 1 , 2 , 3 comprises a device 101 , 201 , 301 for platooning. For longitudinal control, in this example, these vehicles include equipment for cooperative adaptive cruise control (CACC). The formation device comprises: means for wirelessly communicating with radio transmitters and radio receivers for so-called vehicle-to-vehicle (V2V) communication; and data communication processing means arranged to communicate with corresponding The control units 102, 202, 302 of the vehicle control system communicate. The control units 102, 202, 302 are also referred to herein as a group of control units. This wireless communication may be based on any suitable industry standard format,...

Abstract

The invention relates to a method for a string comprising a plurality of vehicles, including a lead vehicle (1) and at least one follower vehicle (2), comprising the follower vehicle (2) following, bymeans of vehicle-to-vehicle (V2V) communication, the lead vehicle (1) in a follower trajectory. The method comprises - generating surroundings data, regarding the surroundings of at least a part of the string, - generating, using the surroundings data, a backup trajectory (BT1), which is different from the follower trajectory, - wherein the generated backup trajectory (BT1), or the surroundings data, is received by at least one of the at least one follower vehicle, - wherein the receiving follower vehicle (2) follows the generated backup trajectory (BT1), upon a determination of a predetermined condition for following the generated backup trajectory (BT1).

Description

technical field [0001] The invention relates to a method for controlling a string comprising a lead vehicle and at least one following vehicle, the method comprising: the following vehicle following the lead vehicle along a following trajectory by means of vehicle-to-vehicle (V2V) communication. The invention also relates to a computer program, a computer readable medium, a control unit or a group of control units, and a vehicle. [0002] The invention can be applied to heavy vehicles such as trucks and buses. Although the invention will be described in relation to a truck, the invention is not limited to this particular vehicle, but may also be used in other vehicles such as cars. Background technique [0003] V2V communication involves information sent between a vehicle and one or more surrounding vehicles over a wireless communication channel. In a convoy in which a following vehicle follows a lead vehicle along a following trajectory by means of V2V communication, the ...
