AMMCOA – Autonomous Mobile Machine Communication for Off-Road Applications - Collaborative Project Highly Reliable and Real-time Networking for Agricultural and Construction Machinery

Project Description

The operation of construction and agricultural machines is subject to particularly high demands on efficiency, precision and safety. Automated and perspective autonomous work are also important concepts, the implementation of which can be decisive for the future viability of relevant products. The operation of construction and agricultural machinery differs in various respects from the Application field "Autonomous and networked driving" in road traffic on digitized roads, so that a separate - but coordinated - consideration of this field of application becomes necessary. Special features of the field of application of construction and agricultural machinery include the non-availability of digitized maps, the need to provide a very accurate relative and absolute location, the very high importance of coordinated use of vehicle fleets (with far-reaching platooning requirements) and the necessity, even in the case of insufficient radio network coverage by network operators (or non-cooperating network operators) a local "5G" communication infrastructure, which is self-sufficient but also integrated into wide networks. The latter is, for example, an important requirement. The term "5G" encompasses the total quantity of all cellular technologies here Edge, HSDPA, LTE, LTE-A and the new 5G air interfaces.

 Goal of this project proposal

The aim of this proposal is to provide a local, mobile and non-infrastructural "tactile internet" networking solution that meets the same local requirements as the "5G Tactile Internet", automatically as an extension into existing broadband networks and thus a dynamic, and customized expansion of the 5G network, additionally provides integrated high-precision localization solutions and addresses the special requirements of the addressed applications.
The solution to be developed is intended to serve as a demand-oriented local expansion of the 5G networks of mobile operators and thus not only be used in the addressed applications, but in all cases in which a 5G-like network between Vehicles and locally placed machines. The 5G-AMMCOA networking concept is thus also a key component for 5G-enabled export products of all industrial equipment, vehicle manufacturers and medical device manufacturers.
The 5G-AMMCOA solution is to be implemented, for example, in the form of on-board units in vehicles, which can network in such application scenarios independently and then realize highly complex work processes between mobile machines. 3 different scenarios are investigated. On the one hand, typical loading operations between an excavator and a truck. Here, the excavator is to adjust to the position of the truck or an appropriate loading position to the truck. The second use case deals with agricultural overloading operations, such as are used, for example, during harvesting between combine harvesters and tractor. An exact relative positioning must be carried out.
Furthermore, changing the transport vehicles requires precise timing and local coordination of the vehicles as well as efficient movement planning of the vehicles. In a third application, a road-building scenario is to be investigated. The challenge lies in coordinating the various construction machines such as road paver, feeder, rollers and trucks. Since the road paver 1 requires a continuous mass flow, the feeder and the trucks have to be coordinated accordingly. Based on the movement of the road finisher, the feeder and road rollers are to be moved to compaction of the material.
