Abstract
Description
Die Erfindung betrifft ein Verfahren zum Betrieb zweier Fahrzeuge, bei dem zwischen den Fahrzeugen Informationen ausgetauscht werden und in wenigstens einem Fahrzeug die empfangenen Informationen zur Steuerung wenigstens einer Sicherheitsmaßnahme verwendet werden.The invention relates to a method for operating two vehicles, in which information is exchanged between the vehicles and in at least one vehicle the received information is used to control at least one safety measure.

Aus der
Der Erfindung liegt die Aufgabe zugrunde, ein verbessertes Verfahren zur Steuerung wenigstens einer Sicherheitsmaßnahme eines Fahrzeugs anzugeben.The invention has for its object to provide an improved method for controlling at least one safety measure of a vehicle.
Die Aufgabe wird erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale gelöst.The object is achieved by the features specified in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Bei dem erfindungsgemäßen Verfahren werden von zwei Fahrzeugen Informationen ausgetauscht und in wenigstens einem Fahrzeug werden die empfangenen Informationen zur Steuerung wenigstens einer Sicherheitsmaßnahme verwendet. Dabei werden von jedem Fahrzeug Signale eines globalen Navigationssystems zur Positionsbestimmung empfangen. Aus den empfangenen Signalen wird von jedem Fahrzeug seine aktuelle Position ermittelt und dem anderen Fahrzeug übermittelt. Von wenigstens einem Fahrzeug wird aus den ermittelten eigenen Positionen und den übermittelten Positionen des anderen Fahrzeugs eine Kollisionswahrscheinlichkeit für die Kollision der Fahrzeuge ermittelt und zur Steuerung wenigstens einer Sicherheitsmaßnahme verwendet.In the method according to the invention, information is exchanged by two vehicles and in at least one vehicle the received information is used to control at least one safety measure. In this case, signals from a global navigation system for position determination are received by each vehicle. From the received signals, each vehicle determines its current position and transmits it to the other vehicle. From at least one vehicle, a collision probability for the collision of the vehicles is determined from the determined own positions and the transmitted positions of the other vehicle and used to control at least one safety measure.
Erfindungsgemäß werden also von den Fahrzeugen Informationen über deren aktuelle Positionen ausgetauscht. Anhand dieser Informationen kann jedes der Fahrzeuge ermitteln, ob eine Kollision mit dem anderen Fahrzeug droht. Entsprechend wird erfindungsgemäß von wenigstens einem der Fahrzeuge eine Wahrscheinlichkeit für die Kollision der beiden Fahrzeuge ermittelt und verwendet, um eine Sicherheitsmaßnahme zu steuern, beispielsweise um ein rechtzeitiges Aufblasen eines Airbags auszulösen. Zuvor können präventive, reversible Insassenschutzsysteme wie ausfahrbare Schutzposter oder reversible Gurtstraffer ausgelöst werden. Es können auch Auslöseschwellen von Insassenschutzsystemen sensibilisiert werden. Dadurch kann die Sicherheit von Fahrzeuginsassen dieses Fahrzeugs vorteilhaft erhöht werden.According to the invention, therefore, information about their current positions is exchanged by the vehicles. Based on this information, each of the vehicles can determine whether a collision with the other vehicle threatens. Accordingly, according to the invention, a probability of the collision of the two vehicles is determined and used by at least one of the vehicles in order to control a safety measure, for example to trigger a timely inflation of an airbag. Previously, preventive, reversible occupant protection systems such as retractable protective posters or reversible belt tensioners can be triggered. It is also possible to sensitize trigger thresholds of occupant protection systems. As a result, the safety of vehicle occupants of this vehicle can be advantageously increased.
Die Ermittelung der aktuellen Position der Fahrzeuge mittels eines globalen Navigationssystems zur Positionsbestimmung ermöglicht dabei vorteilhaft eine sehr genaue Bestimmung der Positionen der Fahrzeuge. Außerdem hat sie den Vorteil, dass zur Bestimmung einer Kollisionswahrscheinlichkeit keine Sensorik zur Erkennung und Lokalisierung anderer Fahrzeuge oder zur Bestimmung von Abständen zu anderen Fahrzeugen benötigt wird. Vielmehr brauchen die Fahrzeuge zur gegenseitigen Erkennung und zur Bestimmung des Abstandes zwischen ihnen lediglich jeweils eine Empfangs- und Auswerteeinheit für Signale des globalen Navigationssystems sowie eine Sende-Empfangseinheit für den Austausch von Informationen mit dem anderen Fahrzeug aufzuweisen.The determination of the current position of the vehicles by means of a global navigation system for position determination advantageously allows a very accurate determination of the positions of the vehicles. In addition, it has the advantage that to determine a collision probability no sensors for detecting and locating other vehicles or for determining distances to other vehicles is needed. Rather, the vehicles for mutual recognition and to determine the distance between them need only each have a receiving and evaluation unit for signals of the global navigation system and a transceiver unit for the exchange of information with the other vehicle.
