Abstract
Description
Die Erfindung betrifft ein Verfahren gemäß Oberbegriff von Anspruch 1, ein Bremssystem gemäß Anspruch 6 sowie ein Computerpragrammprodukt gemäß Anspruch 7.The The invention relates to a method according to the preamble of claim 1, a braking system according to claim 6 and a computer chart product according to claim 7.
Elektronische Kraftfahrzeugbremssysteme der neueren Generation, welche auch unter der Bezeichnung "by-wire"-Bremssysteme bekannt geworden sind, besitzen gegenüber herkömmlichen Bremsystemen flexiblere Eigenschaften auf Grund der Eigenschaft, dass dem Prinzip nach die im herkömmlichen System vorhandene hydraulische Verbindung zwischen Bremspedal und Bremsaktuatorik im "by-wire"-Bremsssystem durch eine elektrische Signalleitung ersetzt ist. Als typische "by-wire"-Bremssysteme sind zum einen elektrohydraulische Systeme (EHB) bekannt, bei denen die Bremsen hydraulisch angesteuert werden, als auch elektromechanische Systeme (EMB), bei denen die Bremsen mittels elektrischer Aktuatoren angesteuert werden.electronic Motor vehicle braking systems of the newer generation, which also under the name "by-wire" brake systems known have become opposite usual Braking systems more flexible properties due to the property that in principle that in the conventional system hydraulic connection between brake pedal and brake actuator in the "by-wire" brake system an electrical signal line is replaced. As typical "by-wire" brake systems are on the one hand known electro-hydraulic systems (EMS), in which the Brakes can be controlled hydraulically, as well as electromechanical Systems (EMB), in which the brakes by means of electrical actuators can be controlled.
Den "by-wire"-Systemen ist gemein, dass die Stellung oder die Bewegung des Pedalweggebers zumindest im Normalbetrieb einen vorn eigentlichen Bremssignal unabhängigen Bremswunsch des Fahrers repräsentiert (bzw. darüber Aufschluss gibt). Der funktionale Zusammenhang zwischen Bremswunsch bzw. Pedalstellung und der eigentlichen Regelgröße (Verzögerung oder Bremsdruck) ist in der elektronischen Bremsenregelungs einrichtung festgelegt. Je nach Fahrzeughersteller sind hier flexible Anpassungsmöglichkeiten zur Einstellung der Bremswirkung oder Charakteristik individuell durch Programmierung oder Verändern von in einem EEPROM gespeicherter Daten einstellbar.The "by-wire" systems have in common that the position or movement of the pedal travel sensor at least in normal operation a brake request independent of the actual brake signal represented by the driver (or above Provides information). The functional connection between braking request or pedal position and the actual control variable (deceleration or brake pressure) set in the electronic brake control device. ever According to the vehicle manufacturer, there are flexible adjustment options here Setting the braking effect or characteristic individually Programming or changing of data stored in an EEPROM adjustable.

Es besteht daher immer noch das Problem anzugeben, wie in Abhängigkeit von einem vorgegebenen Fahrerprofil eine vorhandene Bremsanlage angepasst werden kann.It there is therefore still the problem of specifying how dependent an existing brake system from a given driver profile can be customized.
Diese Aufgabe wird erfindungsgemäß gelöst durch das Verfahren in Anspruch 1.This The object is achieved by the method in claim 1.
Die Erfindung bietet die Möglichkeit, durch Einsatz eines "by-wire"-Bremssystems, die Eigenschaften der Bremse individuell auf den Fahrer anzupassen. Insbesondere ist es möglich, die Wirkung des Bremswunschs, welcher über das Bremspedals eingegeben wird, individuell an die Bremsregelgröße anzupassen. Besonders bevorzugt wird dabei die Stärke der auf. das Fahrzeug wirkenden Verzögerung angepasst. In der Pegel wird dabei gemäß herkömmlicher "by-wire"-Systeme" die Charakteristik des Bremspedals an ein möglichst breites Spektrum von Fahrern angepasst, wobei dabei insbesondere bestimmte Fahrertypvoreinstellungen (Profile) auf an sich bekannte Weise einem Steuerungsrechner im Fahrzeug bereits bekannt sind. Die Anpassung der Charakteristik der Bremse an die einzelnen Fahrertypen erfolgt daher bevorzugt nicht individuell jedes Mal aufs Neue, sondern wird bevorzugt nur einmalig, zum Beispiel bei der Abstimmung des Fahrzeugs bei der Zusammenarbeit des Bremsenherstellers mit dem Kraftfahrzeugherstellers vor der Auslieferung des Fahrzeugs, festgelegt bzw. in Fahrversuchen abgestimmt.The invention offers the possibility of individually adapting the properties of the brake to the driver by using a "by-wire" brake system. In particular, it is possible to individually adapt the effect of the braking request, which is entered via the brake pedal, to the brake control variable. The strength of the is particularly preferred. the vehicle acting deceleration adjusted. In terms of level, the characteristics of the brake pedal are adapted to the widest possible range of drivers in accordance with conventional "by-wire" systems, with certain driver type presettings (profiles) in particular being already known to a control computer in the vehicle in a manner known per se Adapting the characteristics of the brake to the individual driver types is therefore preferably not carried out individually each time anew, but is preferably done only once, for example when the vehicle is coordinated in the cooperation of the brake manufacturer with the motor vehicle manufacturer before delivery of the Vehicle, specified or coordinated in driving tests.
Die Neuerung dieser Erfindung besteht somit in der Verknüpfung der Abstimmungsmöglichkeiten, die eine "by-wire"-Bremsanlage bietet, mit an sich bekannten Fahrer-Memory-Systemen, wie sie z.B. bei der Sitzverstellung entsprechend dem Eingangs genannten Stand der Technik bekannt sind.The The innovation of this invention is thus the combination of Tuning options, which offers a "by-wire" brake system with known ones Driver memory systems, such as with the seat adjustment according to the entrance mentioned State of the art are known.
Nach einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass ein Fahrer in einem individuell für sich oder andere Personen abgespeicherten Benutzerprofil mehrere benutzerspezifische Parameter computergestützt eingeben kann, wie insbesondere einen oder mehrere Parameter aus der Gruppe:
- – Stärke der Pedalcharakteristik (z.B. Dual Rate),
- – Funktionsverlauf der Pedalcharakteristik (z.B. Expotentialfunktion oder linearer Verlauf),
- – Lenkkraftunterstützung,
- – Lenkübersetzung,
- – Schwellenanpassung ESP (z.B. zulässiger Schwimmwinkel) und
- – Gaspedalcharakteristik, etc. gruppiert verwenden kann,
wobei dabei insbesondere eine Veränderung, Speicherung und Ansicht der Daten durch den Fahrer möglich ist.According to a preferred embodiment of the invention, it is provided that a driver can enter a number of user-specific parameters in a user profile that is stored individually for himself or for other people, such as in particular one or more parameters from the group:
- - strength of the pedal characteristics (e.g. dual rate),
- - Functional curve of the pedal characteristic (e.g. expotential function or linear curve),
- - power steering,
- - steering ratio,
- - ESP threshold adjustment (eg permissible float angle) and
- - can use accelerator pedal characteristics, etc. in groups,
whereby the driver can change, store and view the data in particular.
Für diesen Zweck sind selbstverständlich Schnittstellen zur Anpassung dieser Parameter (innerhalb eines sicheren Parameterbereichs) notwendig. Dabei kann es sinnvoll sein, wenn bereits verschiedene vorgegebene Parametersätze oder Charakteristiken für den Fahrer zur Auswahl vorgegeben sind.For this Purpose are a matter of course Interfaces for adapting these parameters (within a secure Parameter range) necessary. It can make sense if various predefined parameter sets or characteristics for the driver are given for selection.
Nachfolgend wird die Erfindung an Hand eines Beispiels näher erläutert.following the invention is explained in more detail using an example.
