Description
Die Erfindung betrifft ein Verfahren zur Erhöhung einer Bremswirkung eines Fahrzeugs nach den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a method for increasing a braking effect of a vehicle according to the features of the preamble of claim 1.
Die
Die
Der Erfindung liegt die Aufgabe zugrunde, ein gegenüber dem Stand der Technik verbessertes Verfahren zur Erhöhung einer Bremswirkung eines Fahrzeugs anzugeben.The invention has for its object to provide a comparison with the prior art improved method for increasing a braking effect of a vehicle.
Die Aufgabe wird erfindungsgemäß durch ein Verfahren zur Erhöhung einer Bremswirkung eines Fahrzeugs mit den Merkmalen des Anspruchs 1 gelöst.The object is achieved by a method for increasing a braking effect of a vehicle having the features of claim 1.
Bevorzugte Ausgestaltungen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.Preferred embodiments and further developments of the invention are specified in the dependent claims.
Beim Verfahren zur Erhöhung einer Bremswirkung eines Fahrzeugs mit einem aktiven Fahrwerk und einem Fahrerassistenzsystem im Falle einer Detektion einer bevorstehenden Kollision wird das aktive Fahrwerk erfindungsgemäß aus einer Betriebsposition in eine Bremsposition verstellt, wobei an Dämpfungsvorrichtungen des Fahrzeugs ein vorgebbarer Ausfederweg eingestellt wird und die Dämpfungsvorrichtungen derart versteift werden, dass eine Federbewegung verhindert ist. Dabei ist der vorgebbare Ausfederweg bevorzugt derart bemessen, dass das Fahrzeug oder eine Fahrzeugkarosserie bei Erreichen des selbigen eine maximale Höhenposition einnimmt und in Fahrzeuglängsachse horizontal ausgerichtet ist.In the method for increasing a braking effect of a vehicle with an active chassis and a driver assistance system in the event of detection of an imminent collision, the active chassis according to the invention is moved from an operating position to a braking position, wherein a specifiable Ausfederweg is set to damping devices of the vehicle and the damping devices stiffened so be that a spring movement is prevented. In this case, the predeterminable rebound travel is preferably dimensioned such that the vehicle or a vehicle body occupies a maximum height position upon reaching the same and is aligned horizontally in the vehicle longitudinal axis.
Durch das Anheben des Fahrzeugs ist ein Verringern einer Fahrzeughöhe im Frontbereich während der Fahrzeugbremsung verhindert, d. h. ein als sogenanntes Bremsnicken bezeichnetes Eintauchen eines Frontbereichs des Fahrzeugs. Auf diese Weise ist beispielsweise bei einer Kollision des Fahrzeugs mit einem anderen Fahrzeug die Gefahr eines Unterfahrens des anderen Fahrzeugs reduziert, d. h. eine Kollision in einem nicht optimalen, zu tiefen Bereich am anderen Fahrzeug.By raising the vehicle, reducing a vehicle height in the front area during vehicle braking is prevented, i. H. a dipping a front portion of the vehicle called a so-called brake-pitch. In this way, for example, in the event of a collision of the vehicle with another vehicle, the risk of underrunning the other vehicle is reduced, i. H. a collision in a non-optimal, too deep area on the other vehicle.
Weiterhin ist durch die Verhinderung von Federbewegungen der Federungs- und Dämpfungsvorrichtungen eine Reibungskraft zwischen Reifen und Fahrbahnoberfläche, auch als Radaufstandskraft bezeichnet, vergrößert.Furthermore, by preventing spring movements of the suspension and damping devices, a frictional force between the tire and the road surface, also referred to as wheel contact force, is increased.
Somit erhöhen sich für eine bestimmte Zeitdauer in gewünschter Weise die Reibungs- und Bremskräfte zwischen Fahrzeug und Fahrbahnoberfläche. Vorteilhafterweise ist die Fahrzeugverzögerung signifikant verbessert oder erhöht und ein Bremsweg bis zum Stillstand des Fahrzeugs wird entsprechend kürzer und/oder eine Aufprallgeschwindigkeit des Fahrzeugs auf ein Hindernis wird reduziert.Thus, the friction and braking forces between the vehicle and the road surface increase in a desired manner for a certain period of time. Advantageously, the vehicle deceleration is significantly improved or increased, and a braking distance until the vehicle stops is correspondingly shorter and / or an impact speed of the vehicle on an obstacle is reduced.
Somit kann beispielsweise vor einem Auffahrunfall des Fahrzeugs auf ein Hindernis eine deutlich höhere kinetische Energie abgebaut werden, als dies mit herkömmlichen Bremsverfahren möglich wäre.Thus, for example, before a rear-end collision of the vehicle with an obstacle, a significantly higher kinetic energy can be dissipated than would be possible with conventional braking methods.
Das erfindungsgemäße Verfahren ist vorteilhafterweise auch bei niedrigen Außentemperaturen und/oder auf unregelmäßigen Fahrbahnoberflächen einsetzbar.The method according to the invention can advantageously also be used at low outside temperatures and / or on irregular road surfaces.
In einer vorteilhaften Ausführungsform ist mittels des erfindungsgemäßen Verfahrens eine Effizienz eines herkömmlichen Bremskissens steigerbar, da ein üblicherweise bei Aktivierung des Bremskissens auftretender Längsverzögerungseinbruch oder -abfall vermieden ist. Als Längsverzögerungseinbruch wird eine Verringerung oder Unterbrechung einer Reibungskraft zwischen Reifen und Fahrbahnoberfläche bedingt durch das Aufsetzen des Bremskissens auf die Fahrbahnoberfläche bezeichnet.In an advantageous embodiment, an efficiency of a conventional brake pad can be increased by means of the method according to the invention, since a longitudinal deceleration or drop which usually occurs when the brake pad is activated is avoided. As a longitudinal deceleration retraction, a reduction or interruption of a frictional force between the tire and the road surface due to the placement of the brake pad is referred to the road surface.
In einer vorteilhaften Ausführungsform kann durch den Entfall des herkömmlichen Bremskissens und eine Verwendung im Fahrzeug vorhandener Komponenten des aktiven Fahrwerks eine Gewichtseinsparung des Fahrzeugs erreicht werden. In an advantageous embodiment, a weight saving of the vehicle can be achieved by eliminating the conventional brake pad and a use in the vehicle existing components of the active chassis.
Weiterhin kann durch den Entfall des herkömmlichen Bremskissens und eine Verwendung im Fahrzeug vorhandener Komponenten des aktiven Fahrwerks eine Kosteneinsparung erreicht werden.Furthermore, a cost saving can be achieved by eliminating the conventional brake pad and a use in the vehicle existing components of the active chassis.
Ausführungsbeispiele der Erfindung werden im Folgenden anhand einer Zeichnung näher erläutert.Embodiments of the invention will be explained in more detail below with reference to a drawing.

Dabei erfolgt die Ansteuerung des Plunger-Aktuators für jedes Fahrzeugrad individuell über ein Regelventil. Zur Energiebereitstellung ist ein Speichersystem und eine Hydraulikpumpe vorgesehen, durch die eine gezielte Ansteuerung des jeweiligen Regelventils vorgenommen werden kann und der jeweils gewünschte bzw. von einem elektronischen System geeignet ausgewählte Plunger-Aktuator mit Hydraulikmedium beaufschlagt oder von diesem entlastet wird.The active chassis can be designed for example as a so-called "Active Body Control" (ABC) system. Such an active body control system, not shown in more detail, consists essentially of a plunger actuator, which is connected in series with a passive steel spring element and with a hydraulic damper parallel thereto, that is, this so-called plunger actuator is essentially in series arranged with a conventional strut of a passenger car. The control of the plunger actuator for each vehicle individually by a control valve. For energy supply, a storage system and a hydraulic pump is provided, through which a targeted control of the respective control valve can be made and the respective desired or by an electronic system suitably selected plunger actuator is acted upon by hydraulic medium or relieved of this.
Alternativ kann das aktive Fahrwerk als herkömmliches Luftfahrwerk ausgebildet sein.Alternatively, the active chassis can be designed as a conventional air suspension.
