Although in some cases CACC systems may limit the propagation of disturbances throughout the vehicle chain due to the extra information compared to ACC, the increase in messages used to convey such information may suffer from network delays or with incomplete message Issues associated with delivery media

Embodiment Construction

[0029] Various communication network topologies may be implemented in the platoon of vehicles.

[0030] figure 1 a, b and c show a first vehicle 101 , a second vehicle 102 , a third vehicle 103 , a fourth vehicle 104 and a fifth vehicle 105 traveling in numerical order. The first vehicle 101 is considered the leader of the convoy.

[0031] figure 1 a shows an example of a leading vehicle-following vehicle fleet communication topology. In this topology, communication 110 occurs between a first vehicle 101 and a second vehicle 102, communication 111 occurs between a second vehicle 102 and a third vehicle 103, and communication 112 occurs between a third vehicle 103 and a fourth vehicle 104 , and communication 113 occurs between fourth vehicle 104 and fifth vehicle 105 .

[0032] In this example, the communication takes the form of a radar detection by a vehicle behind indicating that the vehicle's radar has detected a vehicle ahead. However, it will be appreciated that this...

Abstract

A method and apparatus are provided for controlling a vehicle travelling in a platoon. A first set of information is received at a first vehicle in a platoon, the first set of information relating toat least one other vehicle in the platoon. One of a plurality of control algorithms is selected in dependence on the first set of information, wherein each of the plurality of control algorithms corresponds to a respective platoon communication topology. The first vehicle is controlled in response to the first set of information and the selected one of the control algorithms.

Description

technical field [0001] This application relates to the automatic control of vehicles in the form of a platoon, and in particular to the use of inter-vehicle communication in the automatic platooning of vehicles. Background technique [0002] Intelligent Transport Systems (ITS) are systems aimed at improving road safety zones by broadcasting real-time information about road conditions. For example in such systems, cars or similar vehicles may broadcast information such as location, speed, road conditions, events and / or accidents, and the like. This information can be shared between vehicles using so-called vehicle-to-vehicle (V2V) communication and between vehicles and other units such as roadside entities or traffic control units using vehicle-to-infrastructure (V2I) communication. These communication systems may use IEEE 802.11p Dedicated Short Range Communication (DSRC) technology. [0003] One application of ITS may provide vehicle platooning. Such vehicle platooning a...
