Abstract
Die Erfindung stellt ein Verfahren zum Schutz von Insassen einer Fahrgastzelle eines Kraftfahrzeuges (10) mit dem folgenden Merkmal bereit: Bei einem Frontalaufprall des Kraftfahrzeuges (10) wird ein Unterstützungsmotor (13) eines elektrischen Bremskraftverstärkers (11) des Kraftfahrzeuges (10) derart angesteuert, dass das Bremspedal (12) aus der Fahrgastzelle zurückgezogen wird.Die Erfindung stellt ferner eine entsprechende Vorrichtung, ein entsprechendes Computerprogramm sowie ein entsprechendes Speichermedium bereit.The invention provides a method for protecting occupants of a passenger compartment of a motor vehicle (10) with the following feature: in a frontal collision of the motor vehicle (10), a support motor (13) of an electric brake booster (11) of the motor vehicle (10) is controlled in such a way that that the brake pedal (12) is withdrawn from the passenger compartment. The invention further provides a corresponding apparatus, a corresponding computer program and a corresponding storage medium.
Description
Die vorliegende Erfindung betrifft ein Verfahren zum Schutz von Insassen einer Fahrgastzelle eines Kraftfahrzeuges. Die vorliegende Erfindung betrifft darüber hinaus eine entsprechende Vorrichtung, ein entsprechendes Computerprogramm sowie ein entsprechendes Speichermedium.The present invention relates to a method for protecting occupants of a passenger compartment of a motor vehicle. The present invention also relates to a corresponding device, a corresponding computer program and a corresponding storage medium.
Ein Bremskraftverstärker (BKV) ermöglicht in der Kraftfahrzeug- und Bremstechnik die Verringerung der Betätigungskraft an der Bremse eines Fahrzeugs, die zum Erreichen einer gewünschten Bremswirkung benötigt wird. Bekannt sind neben den in Pkw und leichten Nutzfahrzeugen üblicherweise verbauten Unterdruck-Bremskraftverstärkern insbesondere hydraulische oder elektrische Bremskraftverstärker.A brake booster (BKV) in motor vehicle and brake technology enables the reduction of the operating force on the brake of a vehicle, which is needed to achieve a desired braking effect. In addition to the normally built in passenger cars and light commercial vehicles vacuum brake boosters are known in particular hydraulic or electric brake booster.
Durch die Verformung der Stirnwand im Crashfall werden Pedalerie und BKV in den Fahrgastinnenraum gedrückt. Dabei verlagert sich das Bremspedal in Richtung Brems-Fuß des Fahrers. Beim bremsenden Crash befindet sich der Fuß auf dem Bremspedal. Somit kann durch den Crash ein zusätzlicher Krafteintrag auf den Fuß entstehen, der das Verletzungsrisiko erhöht.Due to the deformation of the front wall in the event of a crash, pedals and BKV are pushed into the passenger compartment. The brake pedal shifts towards the driver's brake foot. During the braking crash, the foot is on the brake pedal. Thus, the crash can create an additional force on the foot, which increases the risk of injury.
Nach dem Stand der Technik wird für diesen Fall die direkte Kopplung von Bremspedal und Bremsgerät durch Durchbrechen der Druckstange oder der Bremspedallagerung aufgehoben; bekannt ist ferner eine Begrenzung der Eindringtiefe durch Anschlag des Bremspedals an einem Anschlaghalter.According to the prior art, the direct coupling of brake pedal and brake device is canceled by breaking the push rod or the brake pedal bearing for this case; Also known is a limitation of the penetration depth by stopping the brake pedal on a stop holder.
Die Erfindung stellt ein Verfahren zum Schutz von Insassen einer Fahrgastzelle eines Kraftfahrzeuges, eine entsprechende Vorrichtung, ein entsprechendes Computerprogramm sowie ein entsprechendes Speichermedium gemäß den unabhängigen Ansprüchen bereit.The invention provides a method for protecting occupants of a passenger compartment of a motor vehicle, a corresponding device, a corresponding computer program and a corresponding storage medium according to the independent claims.
Der erfindungsgemäße Ansatz fußt hierbei auf der Erkenntnis, dass auch durch den Einsatz von elektrischen Bremskraftverstärkern, wie sie von Automobilzulieferern etwa als sogenannte One-Box-Systeme vertrieben werden, im Crash-Fall durch Ansteuerung des Unterstützungsmotors das Bremspedal zurückgezogen und ggf. kraftlos gestellt werden kann.The approach according to the invention is based here on the knowledge that the use of electric brake boosters, such as those sold by automotive suppliers as so-called one-box systems, in the event of a crash, retracts the brake pedal and activates it if necessary by activating the assisting motor can.
Ein Vorzug dieser Lösung liegt in der Verhinderung eines Eindringens des Bremspedals. Zusätzliche Rückhalteelemente werden nicht benötigt, was zudem eine kostengünstige Fertigung ermöglicht.An advantage of this solution is the prevention of intrusion of the brake pedal. Additional retaining elements are not needed, which also allows a cost-effective production.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Patentansprüchen angegeben.Further advantageous embodiments of the invention are specified in the dependent claims.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden näher beschrieben.An embodiment of the invention is illustrated in the drawing and will be described in more detail below.
