Abstract
Description
Die Erfindung betrifft ein Verfahren zur Steuerung einer Bremsanlage eines stehenden oder beinahe stehenden Fahrzeugs zur Verminderung von Folgen einer Kollision mit einem anderen Fahrzeug.The The invention relates to a method for controlling a brake system a standing or almost stationary vehicle for reduction from consequences of a collision with another vehicle.
Moderne
Fahrzeuge verfügen über Bremsanlagen,
die unter bestimmten Bedingungen durch elektrische Betätigung aktiv
Bremskraft an den Rädern
aufbauen, die größer ist,
als die Fahrervorgabe und teilweise unabhängig von dieser ist, wie es

Es ist Aufgabe der Erfindung, ein unkompliziertes Verfahren anzubieten, das ein automatisches Auslösen der Bremsanlage eines stehenden oder beinahe stehenden Fahrzeugs im Falle einer erkannten Kollisionsgefahr mit einem sich von hinten nähernden Fahrzeug gewährleistet. Dies wird durch das Merkmal des unabhängigen Patentanspruchs erreicht.It It is an object of the invention to provide an uncomplicated method, that an automatic trigger the brake system of a stationary or almost stationary vehicle in the case of a detected risk of collision with one from behind approaching Vehicle guaranteed. This is achieved by the feature of the independent claim.
Vorteile der ErfindungAdvantages of the invention
Durch das erfindungsgemäße Verfahren wird eine Notsituation erkannt, in der sich einem stehenden Fahrzeug ein anderes Fahrzeug von hinten gefährlich nähert und die Insassen des stehenden Fahrzeugs durch Auffahren des anderen Fahrzeugs und die dadurch verursachte starke Beschleunigung gefährdet werden. Durch das erfindungsgemäße Verfahren wird diese Beschleunigung wesentlich vermindert, weil die Bremsanlage bereits vor der Kollision aktiviert wird. Dabei ist von besonderem Vorteil, daß dies ohne zusätzliche Sensoren oder einen anderen apparativen Mehraufwand erreicht wird. Besonders vorteilhaft ist, daß die erfindungsgemäße automatische Bremsung nur im Stillstand ausgelöst wird, so daß keine Gefährdung durch Fehlauslösungen entsteht und im Gegensatz zu den bekannten Systemen zur automatischen Bremsung weniger komplexe Sicherheitskonzepte erforderlich sind.By the inventive method An emergency situation is detected in which a stationary vehicle Another vehicle approaching dangerously from behind and the occupants of the standing Vehicle by driving up the other vehicle and thereby caused severe acceleration. By the method according to the invention This acceleration is significantly reduced because the brake system already activated before the collision. It is of special Advantage that this without additional Sensors or other additional equipment is achieved. It is particularly advantageous that the automatic according to the invention Braking is triggered only at standstill, so that no endangering by false triggering arises and in contrast to the known systems for automatic Braking less complex safety concepts are required.
Prinzipiell könnte die Bremse im Stillstand immer aktiviert werden, durch die erfindungsgemäße Aktivierung nur im Falle einer erkannten Kollisionsgefahr wird der schnelle Verschleiß der Bremsenaktorik vermieden.in principle could the brake at standstill always be activated by the activation of the invention only in case of a detected risk of collision is the fast Wear the Brake actuator avoided.

Beschreibung von AusführungsbeispielenDescription of exemplary embodiments
Das Fahrzeug wird in der Regel durch die Pedalbetätigung des Fahrers im Stillstand gehalten. Die zum Stillstand notwendige Bremskraft ist im allgemeinen gegenüber der während des Bremsvorgangs aufgebrachten Bremskraft geringer. Daher kann bei einem Auffahrunfall das stehende Fahrzeug trotz der Bremsenbetätigung verschoben werden. Wenn ein Fahrzeug von hinten auf das stehende Fahrzeug auffährt, wird das Fahrzeug stark beschleunigt und aufgrund der Massenträgheit der Kopf der Fahrzeugsinsassen dadurch zunächst nach hinten und danach relativ zum Fahrzeug nach vorne geschleudert, wobei der Rumpf durch den Gurt zurückgehalten wird. Sowohl die nach vorne als auch die nach hinten gerichtete Bewegung des Kopfes kann zu Verletzungen im Bereich der Halswirbelsäule führen. Diese Gefahr wird durch das erfindungsgemäße Verfahren stark reduziert.The Vehicle is usually stopped by the driver pedaling held. The braking force necessary to stop is in general across from while the braking applied braking force less. Therefore, can in a rear-end collision, the stationary vehicle shifted despite the brake application become. When a vehicle drives from behind onto the stationary vehicle, it will the vehicle accelerates greatly and due to the inertia of the Head of the vehicle occupants first to the back and then hurled forward relative to the vehicle, with the fuselage passing through retained the strap becomes. Both the forward and the backward Movement of the head can lead to injuries in the area of the cervical spine. These Danger is greatly reduced by the method according to the invention.

Im
Schritt
Zur Umsetzung der Bremsung wird ein elektrohydraulisches Bremssystem, ein elektropneumatisches oder ein elektromotorisches Bremssystem benutzt.to Implementation of the braking is an electro-hydraulic braking system, an electropneumatic or an electromotive braking system used.
Die Kommunikation unter den verschiedenen beteiligten Systemen kann über ein Bussystem, beispielsweise den CAN-Bus des Fahrzeugs erfolgen.The Communication among the various systems involved can be over Bus system, for example, the CAN bus of the vehicle done.
In einem anderen Ausführungsbeispiel kann die automatische Bremsung beendet werden, wenn das Fahrzeug nach der Kollision wieder zum Stillstand kommt, wobei dies zum Beispiel mittels Raddrehzahl-, Beschleunigungs- und/oder Gierratensensoren ermittelt wird.In another embodiment The automatic braking can be stopped when the vehicle after the collision comes to a standstill, this being for example by means of wheel speed, acceleration and / or yaw rate sensors is determined.
