Abstract

The automatically-operating crash safety system may apply the brakes after an impact when the vehicle speed has dropped to zero. The system includes an electronic control module and the brake application program is triggered when the airbag is deployed or the safety belt tightening mechanism is activated by an impact.

Description

Die Erfindung bezieht sich auf eine Fahrsicherheitsvorrichtung.The Invention relates to a driving safety device.

Derzeit sind Fahrsicherheitsvorrichtungen bekannt, die einen Zusammenstoß eines Kraftfahrzeugs mit anderen Fahrzeugen oder Objekten verhindern sollen. Bspw. beschreibt die DE 199 49 809 A1 eine Fahrsicherheitsvorrichtung in einem Kraftfahrzeug, die mit einer Objekterfassungseinrichtung Objekte vor dem Kraftfahrzeug erfasst und bei einem möglichen Zusammenstoß des Kraftfahrzeugs mit dem erfassten Objekt das Kraftfahrzeug automatisch abbremst.Driving safety devices are currently known which are intended to prevent a motor vehicle from colliding with other vehicles or objects. For example. describes the DE 199 49 809 A1 a driving safety device in a motor vehicle that detects objects in front of the motor vehicle with an object detection device and automatically brakes the motor vehicle in the event of a possible collision of the motor vehicle with the detected object.

Kann der Zusammenstoß nicht mehr verhindert werden, sind Vorrichtungen bekannt, die ein Warnsignal abgeben. Es wird z. B. die Warnblinkanlage eingeschalten, sobald ein Airbag gezündet worden ist.can the collision doesn't Devices are more known to prevent a warning signal submit. It is e.g. B. switched on the hazard warning lights as soon as an airbag detonated has been.

Aufgabe der Erfindung ist, eine Fahrsicherheitsvorrichtung in der Weise zu verbessern, dass bei einem Zusammenstoß des Kraftfahrzeugs mit einem weiteren Objekt fahrspezifische Sicherheitsmaßnahmen eingeleitet werden.task of the invention is a driving safety device in the manner to improve that in the event of a collision of the motor vehicle with another Object driving-specific safety measures are initiated.

Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung nach Patentanspruch 1 gelöst. Vorteilhafte Weiterbildungen sind die Gegenstände der abhängigen Ansprüche.This The object is achieved by a Device according to claim 1 solved. Advantageous further training are the objects the dependent Expectations.

Die erfindungsgemäße Fahrsicherheitsvorrichtung zum automatischen Bremsen eines Kraftfahrzeugs startet einen automatischen Bremsvorgang wenn eine Fahrer-Sicherheitsvorrichtung ausgelöst wird.The Driving safety device according to the invention for automatic braking of a motor vehicle starts an automatic one Braking when a driver safety device is triggered.

Bei einer Kollision eines Kraftfahrzeugs mit einem anderen Verkehrsteilnehmer oder Objekt, ist der Fahrer oft nicht mehr in der Lage, das Bremspedal zu betätigen, da er unter Schock steht oder verletzt ist. Es kann auch zu einem unkontrolliertem Bremsvorgang kommen, wenn das Kraftfahrzeug zu schleudern beginnt. Es kann auch zu einem Teilbremsvorgang kommen, wenn der Fahrer bspw. mit seinem Fuß vom Bremspedal abrutscht. Um unkontrollierte Kraftfahrzeugbewegungen und mögliche Folgekollisionen des Kraftfahrzeugs nach dem Zusammenstoß zu vermeiden, löst die Fahrsicherheitsvorrichtung ein Signal aus, das den automatischen Bremsvorgang startet. Die Fahrsicherheitsvorrichtung kann ein separates Steuergerät sein, im Bremssteuergerät oder im Steuergerät für die Fahrersicherheitsvorrichtung integriert sein. Das Signal wird erfindungsgemäß dann ausgelöst, wenn eine Fahrer-Sicherheitsvorrichtung wegen eines Zusammenstoßes des Kraftfahrzeugs mit einem anderen Objekt ausgelöst wird. Die Fahrer-Sicherheitsvorrichtungen dienen dazu, dem Fahrer des Kraftfahrzeugs im Falle einer Kollision vor vermeidbaren Verletzungen zu schützen.at a collision between a motor vehicle and another road user or object, the driver is often no longer able to use the brake pedal to operate because he is in shock or injured. It can also become one uncontrolled braking comes when the motor vehicle skid starts. Partial braking can also occur if the Driver, for example, with his foot off Brake pedal slips. About uncontrolled motor vehicle movements and possible To avoid subsequent collisions of the motor vehicle after the collision, solves the Driving safety device emits a signal indicating the automatic braking starts. The driving safety device can be a separate control unit, in the brake control unit or in the control unit for the Driver safety device to be integrated. According to the invention, the signal is triggered when a driver safety device due to a collision of the Motor vehicle is triggered with another object. The driver safety devices serve the driver of the motor vehicle in the event of a collision protect against avoidable injuries.

Vorteilhafterweise ist die Fahrer-Sicherheitsvorrichtung ein Airbag und/oder ein Gurtstraffer. Kommt es zu einer Kollision des Kraftfahrzeugs mit einem weiteren Verkehrsteilnehmer oder Objekt, wird z. B. der Fahrerairbag ausgelöst. Um die Wegstrecke des Kraftfahrzeugs bis zum Stillstand erheblich zu reduzieren, kann gleichzeitig mit dem Auslösen des Airbags das Signal zum starten des automatischen Bremsvorgangs gesendet werden. Das Gleiche gilt für den Gurtstraffer. Sobald dieser aktiviert wird, kann das Signal zum starten des automatischen Bremsvorgangs gestartet werden. Das Signal kann den Bremsvorgang ohne Zeitverzögerung starten. Dadurch kann sich das Risiko von Folgeschäden am Kraftfahrzeug verringern.advantageously, the driver safety device is an airbag and / or a belt tensioner. comes there is a collision between the motor vehicle and another road user or object, e.g. B. triggered the driver airbag. To the distance of the motor vehicle can significantly reduce to a standstill at the same time triggering the airbag the signal to start the automatic braking process be sent. The same applies to the belt tensioner. As soon as this is activated, the signal to start the automatic Braking process can be started. The signal can brake without time delay start. This can reduce the risk of consequential damage to the motor vehicle reduce.

Wenn das Fahrzeug mit einer dynamischen Stabilitätskontrolle (DSC bzw. ESP) ausgerüstet ist, wird das Kraftfahrzeug vorteilhafterweise bei gesendetem Signal mit dynamischer Stabilitätskontrolle gebremst. Dadurch kann sichergestellt werden, dass das Kraftfahrzeug während des Bremsvorganges steuerbar bleibt und somit das Risiko einer Kollision mit weiteren Verkehrsteilnehmern oder Hindernissen verringert wird.If the vehicle with a dynamic stability control (DSC or ESP) equipped the motor vehicle is advantageously when the signal is sent with dynamic stability control braked. This can ensure that the motor vehicle while the braking process remains controllable and thus the risk of a collision with other road users or obstacles is reduced.

Vorteilhafterweise wird bei einer Geschwindigkeit des Kraftfahrzeugs von nahezu Null der automatische Bremsvorgang abgeschalten, damit das Kraftfahrzeug abtransportiert werden kann. Ist das Kraftfahrzeug nach der Kollision z. B. nicht mehr fahrtauglich, muss dieses abgeschleppt werden. Hierbei ist es hilfreich, wenn die Bremsen gelöst sind. Um dies sicherzustellen, können in der vorteilhaften Ausgestaltung bei Stillstand des Fahrzeugs die Bremsen durch Abschalten des automatischen Bremsvorgangs gelöst werden.advantageously, becomes at a speed of the motor vehicle of almost zero the automatic braking is switched off so that the motor vehicle can be transported away. Is the motor vehicle after the collision z. B. no longer roadworthy, this must be towed. It is helpful when the brakes are released. To ensure this can in the advantageous embodiment when the vehicle is stationary the brakes are released by switching off the automatic braking process.

Es können eine Vielzahl weiterer Details durchaus abweichend von obiger Beschreibung gestaltet sein, ohne den Inhalt der Patentansprüche zu verlassen.It can a variety of other details quite different from the above description be designed without leaving the content of the claims.
