Abstract
Die Erfindung betrifft ein Verfahren zum ruckfreien Anhalten eines mit einer Rundumsensorik 6 ausgestatteten Fahrzeugs 1, bei dem bei einem Bremsvorgang das durch den Bremsvorgang verursachte Nicken des Fahrzeugs 1 durch einen Bremseingriff minimiert wird. Bei Einleitung eines Bremsvorgangs werden Signale der Rundumsensorik 6 auf eine drohende Kollisionsgefahr überprüft. Ein das Nicken des Fahrzeugs 1 minimierender Bremseingriff unterbleibt, wenn aufgrund der von der Rundumsensorik 6 gelieferten Signale auf ein Kollisionsrisiko geschlossen wird.The invention relates to a method for jerk-free stopping of a vehicle 1 equipped with an all-round sensor system 6, in which during a braking operation the pitching of the vehicle 1 caused by the braking operation is minimized by a braking intervention. When braking is initiated, signals from the all-round sensor system 6 are checked for an impending risk of collision. A braking intervention that minimizes the pitching of the vehicle 1 does not take place if a collision risk is inferred on the basis of the signals supplied by the all-round sensor system 6.
Description
Die Erfindung betrifft ein Verfahren und eine Einrichtung zum ruckfreien Anhalten eines Fahrzeugs nach dem Oberbegriff der unabhängigen Ansprüche 1 und 7.The The invention relates to a method and a device for jerk-free Stopping a vehicle according to the preamble of independent claims 1 and 7th
Bei mit einer elektrohydraulischen Bremse ausgestatteten Fahrzeugen wird ein ruckfreies Anhalten dadurch ermöglicht, dass durch eine entsprechende Ansteuerung der Bremse mittels einer Steuereinrichtung die mit dem Bremsvorgang einhergehende Nickbewegung der Karosserie des Fahrzeugs kurz vor dem Fahrzeugstillstand minimiert wird. Diesen Bremseingriff empfindet der Fahrer als im Wesentlichen ruckfreies Abbremsen in den Stillstand. Das ruckfreie Abbremsen verlängert jedoch den Bremsweg. Es ist daher auch schon bekannt, die Steuereinrichtung so zu betreiben, dass bei schnell eingeleiteten Bremsvorgängen oder einer Vollbremsung die Funktion ruckfreies Anhalten nicht aktiviert wird, um den Bremsweg so kurz wie möglich zu halten.at vehicles equipped with an electro-hydraulic brake a smooth stop is made possible by a corresponding Control of the brake by means of a control device with the Braking accompanying pitching movement of the vehicle body short is minimized before the vehicle comes to a standstill. This brake intervention the driver perceives as essentially jerk-free braking the standstill. The smooth braking, however, extends the braking distance. It is therefore also known to operate the control device in such a way that when braking is initiated quickly or when the brakes are applied hard the jerk-free stopping function is not activated by the braking distance as short as possible to keep.
Aus
Die Erfindung bezweckt eine vorteilhafte Weiterentwicklung des bekannten Systems, um einerseits von dem gesteigerten Komfort einer derartigen Bremsanlage mit der Funktion ruckfreies Anhalten zu profitieren, andererseits aber einem gesteigerten Sicherheitsaspekt zu genügen. Die Erfindung geht dabei von der Erkenntnis aus, dass in besonders kritischen Gefährdungssituationen auch schon ein geringer Zugewinn an Bremsweg für die Sicherheit dienlicher sein kann als ein gesteigerter Komfort. Die Erfindung ermöglicht daher ein frühzeitiges Erkennen von Situationen, in denen es sinnvoller ist, auf die Komfortfunktion ruckfreies Anhalten zu verzichten, um Bremsweg zu gewinnen.The The invention aims at an advantageous further development of the known one Systems, on the one hand, from the increased comfort of such Brake system with the function to benefit from smooth stopping, on the other hand, to meet an increased security aspect. The Invention is based on the knowledge that in particularly critical hazardous situations even a small gain in braking distance more useful for safety can be as an increased comfort. The invention therefore enables an early one Recognize situations in which it makes more sense on the comfort function avoid jerk-free stopping to gain braking distance.
