Abstract:
Die Erfindung betrifft ein Verfahren zum Bewegen einer ein erstes Fahrzeug (f1) und wenigstens ein dem ersten Fahrzeug (f1) folgendes zweites Fahrzeug (f2) aufweisenden Fahrzeugkolonne (10), bei welchem die Fahrzeuge (f1, f2) auf Basis einer der Fahrzeugkolonne (10) zugeordneten, vorgebbaren Gesamtbetriebsstrategie (G) zumindest vorübergehend in einem vorgebbaren, gleichbleibenden Abstand (d2) zueinander entlang einer Fahrstrecke (12) bewegt werden, wobei: - für das jeweilige Fahrzeug (f1, f2) der Fahrzeugkolonne (10) in Abhängigkeit von einem vorausliegenden Streckenprofil (16) eine jeweilige Einzelbetriebsstrategie (E1, E2) vorgegeben wird, wobei sich die Einzelbetriebsstrategien (E1, E2) der Fahrzeuge (f1, f2) voneinander unterscheiden, - im Rahmen der Gesamtbetriebsstrategie (G) der Abstand (d2) der Fahrzeuge (f1, f2) vergrößert wird, bevor die Fahrzeugkolonne (10) das Streckenprofil (16) erreicht, - das jeweilige Fahrzeug (f1, f2) auf Basis der jeweiligen Einzelbetriebsstrategie (E1, E2) entlang des Streckenprofils (16) bewegt wird, und - die Fahrzeugkolonne (10) nach Zurücklegen des Streckenprofils (16) auf Basis der Gesamtbetriebsstrategie (G) bewegt wird.
Abstract:

Abstract:
A system (4) and method to control a vehicle platoon that comprises at least one lead vehicle and one additional vehicle, each of which has a positioning unit (1 ) and a unit (2) for wireless communication. The system comprises a driving profile unit (6) configured to determine two different common driving strategies adapted to be applied for all vehicles in the vehicle platoon, whereby these driving strategies are constituted by a common position-based driving strategy and a common time-based driving strategy. The system comprises an analysis unit (7) that is configured to: - receive and evaluate one or several driving strategy criteria values (8), - determine whether the said time-based driving strategy or position-based driving strategy is to be used, depending on the result of the said evaluation, - generate a driving strategy signal that indicates the driving strategy that has been determined, and - transmit the driving strategy signal to all vehicles in the vehicle platoon that are affected by the driving strategy, after which the vehicles in the vehicle platoon are controlled according to the driving strategy.
Abstract:
A method and a system to control a vehicle platoon that comprises at least one leader vehicle and one further vehicle, each of which has a positioning unit and a unit for wireless communication. The method comprises to provide a driving profile for at least one vehicle f k in the vehicle platoon along a road horizon for the road ahead of the vehicle, wherein the driving profile contains target values b, and associated positions p, for the vehicle f k along the road horizon, to determine a position-based driving strategy for the vehicles in the vehicle platoon, based on at least the driving profile for the vehicle f k , after which the vehicles in the vehicle platoon are controlled according to the position-based driving strategy.
Abstract:
In one embodiment, a method comprising identifying field boundaries from aerial imagery; detecting entry upon a first field by an agricultural machine without operator intervention, the first field within the identified field boundaries; and providing a first path to be traversed in the first field at least in part by the agricultural machine.
Abstract:
A method is provided for controlling a hybrid vehicle powertrain, including recording a starting and ending point of a desired route, determining an optimally fuel efficient route, and executing a powertrain control strategy based on the route. Real-time traffic data and topographical data are continuously evaluated, and th route and powertrain control strategy are updated based on the data. A hybrid vehicle also provided having an engine, a motor/generator, a battery, and a navigation system receiving a route starting point and ending point. A powertrain control module (PCM) detects the battery charge and determines a powertrain strategy along an optimally fuel efficient route based on the detected charge level when the points are selected, and sustains the charge level in the absence of user-selected route points. Sensors receive real-time traffic data, and the navigation system includes topographical data for determining the optimally fuel efficient route.
