Abstract
Description
Die Erfindung betrifft ein Verfahren zur Ansteuerung eines Bremssystems gemäß Oberbegriff des Anspruchs 1 und ein Bremssystem gemäß Oberbegriff von Anspruch 14.The invention relates to a method for controlling a brake system according to the preamble of claim 1 and a brake system according to the preamble of
Die
Hybridfahrzeuge weisen neben Verbrennungsmotoren auch elektrische Fahrzeugantriebe auf, welche dabei einerseits aus einem Energiespeicher gespeist als Motor verwendet werden, andererseits ist auch eine Verwendung als Generator möglich. Beim Bremsen kann somit zumindest ein Teil der Bewegungsenergie zurückgewonnen werden, wobei der Energiespeicher aufgeladen wird. Um in jeder Situation eine ausreichende Verzögerung sicherzustellen, müssen die Fahrzeugräder zusätzlich auch mit Reibbremsen ausgestattet sein. Daher setzt sich das Bremsmoment mindestens einer Achse des Hybridfahrzeugs bei diesem auch als Rekuperation bezeichneten Vorgehen aus hydraulisch oder elektromechanisch erzeugtem Reibbremsmoment und generatorisch erzeugtem Schleppmoment zusammen.Hybrid vehicles have in addition to internal combustion engines and electric vehicle drives, which are fed on the one hand from an energy storage used as an engine, on the other hand, a use as a generator is possible. When braking can thus be recovered at least a portion of the kinetic energy, the energy storage is charged. In order to ensure a sufficient delay in any situation, the vehicle wheels must also be equipped with friction brakes. Therefore, the braking torque is at least one axis of the hybrid vehicle in this also known as recuperation procedure from hydraulically or electromechanically generated friction brake torque and regenerated generated drag torque together.
Das durch die Rekuperation erzeugte Bremsmoment des Generators hängt hierbei unter anderem von dem Zustand des Energiespeichers ab. Ist dieser voll geladen, so kann keine weitere Energierückgewinnung stattfinden. Um ein gleichbleibendes Pedalgefühl bereitzustellen, wird daher häufig ein Pedalsimulator in Verbindung mit einer mechanischen Entkopplung des Bremspedals von den Radbremsen eingesetzt. Solche Systeme sind aufwendig und kostenintensiv.The braking torque of the generator generated by the recuperation depends inter alia on the state of the energy storage. If this is fully charged, no further energy recovery can take place. To provide a consistent pedal feel, therefore, a pedal simulator is often used in conjunction with a mechanical decoupling of the brake pedal of the wheel brakes. Such systems are expensive and expensive.

Die genannten Schriften offenbaren Bremssysteme, bei denen das vom Fahrer betätigte Bremspedal ab einem gewissen Mindestpedalbetätigungswinkel unter mechanischer Verbindung mit dem oder den Hauptzylinder(n) steht, die einen Druckaufbau in den Radbremsen erzeugen. Die Betätigung des Bremspedals wird vorzugsweise von einem Vakuumbremskraftverstärker unterstützt, so dass mit moderaten Pedalkräften ein erhöhter Druckaufbau stattfindet. Da moderne Verbrennungsmotoren häufig kein hinreichendes Vakuum mehr bereitstellen und elektrische Fahrzeugantriebe prinzipiell nicht zur Vakuumerzeugung in der Lage sind, muss in bestimmten Fällen eine spezielle Vakuumpumpe hinzugefügt werden. Dies ist wegen des erhöhten Gewichts, der erhöhten Lautstärke und des erhöhten Energieverbrauchs nicht immer wünschenswert.The cited documents disclose brake systems in which the brake pedal actuated by the driver is, starting from a certain minimum pedal operating angle, in mechanical connection with the master cylinder (s) which generate pressure in the wheel brakes. The operation of the brake pedal is preferably supported by a vacuum brake booster, so that with moderate pedal forces an increased pressure build-up takes place. Because modern combustion engines often no longer provide sufficient vacuum and Electric vehicle drives are not in principle capable of generating a vacuum, in certain cases, a special vacuum pump must be added. This is not always desirable because of increased weight, increased volume and increased energy consumption.
Aufgabe der vorliegenden Erfindung ist es, ein regeneratives Bremssystem bereitzustellen, welches kostengünstig in ein zumindest teilweise elektrisch angetriebenes Fahrzeug integriert werden kann.Object of the present invention is to provide a regenerative braking system, which can be inexpensively integrated into an at least partially electrically powered vehicle.
Diese Aufgabe wird erfindungsgemäß durch das Bremssystem gemäß Anspruch 1 gelöst.This object is achieved by the braking system according to claim 1.
Es wird also ein Verfahren bereitgestellt, bei dem eine Steuerung eines Bremssystems in einem insbesondere drei Räder aufweisenden Kraftfahrzeug durchgeführt wird, wobei das Kraftfahrzeug zumindest mit einem elektrischen Fahrzeugantrieb und einem mindestens einen Bremskreis umfassenden schlupf- und/oder traktions- und/oder fahrdynamikgeregelten Bremssystem mit hydraulischen Reibbremsen ausgestattet ist, wobei das vom Fahrer betätigte Bremspedal ohne Hilfskraftunterstützung in direkter mechanischer Verbindung mit dem primären Bremsdruckerzeugungsmittel steht, und wobei sich das Gesamtbremsmoment an mindestens einer Achse zumindest zeitweise aus elektrisch-regenerativem Schleppmoment und Reibbremsmoment zusammensetzt. Bei einer Bremsanforderung durch den Fahrer wird überprüft, ob ein Maß für die Bremsanforderung einen ersten Schwellwert überschreitet, und bei Überschreiten des ersten Schwellwerts findet in mindestens einem Bremskreis (I) mittels einer Hydraulikpumpe (
Zweckmäßigerweise wird oder werden als Maß für die Bremsanforderung die angeforderte Verzögerung berechnet und/oder aufgebauter Bremsdruck und/oder Bremspedalweg und/oder Bremspedalwinkel und/oder Verfahrweg des Tandemhauptzylinders gemessen. Besonders kostengünstig ist es, wenn der von einem in schlupfgeregelten Bremssystemen vielfach bereits vorhandenen Drucksensor am Tandemhauptbremszylinder gemessene Druck als Maß für die Bremsanforderung verwendet wird.The requested deceleration is expediently calculated or measured as a measure for the braking request and / or the brake pressure and / or brake pedal travel and / or brake pedal angle and / or travel of the tandem master cylinder are measured. It is particularly cost-effective if the pressure measured at the tandem master brake cylinder by a pressure sensor which is already widely used in slip-controlled brake systems is used as a measure of the braking demand.
Es ist vorteilhaft, wenn die für den Druckaufbau benötigte Hydraulikflüssigkeit von einem teilweise gefüllten Druckspeicher (
Vorzugsweise wird der erste Schwellwert für das Einsetzen des zusätzlichen Druckaufbaus abhängig von der Fahrzeuggeschwindigkeit gewählt. Die von einem Generator zur Verfügung gestellte Verzögerung ist von der Fahrzeuggeschwindigkeit abhängig. Wird ein fester Zusammenhang zwischen Bremspedalbetätigung und Bremskraft angestrebt, so kann dies durch eine Anpassung der Einsatzschwelle für einen zusätzlichen Druckaufbau mittels einer Hydraulikpumpe erfolgen.Preferably, the first threshold for the onset of additional pressure build-up is selected depending on the vehicle speed. The delay provided by a generator depends on the vehicle speed. If a firm connection between brake pedal actuation and braking force is desired, this can be done by adjusting the deployment threshold for additional pressure buildup by means of a hydraulic pump.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist die erste Rate des zusätzlichen Druckaufbaus konstant. Somit kann die Ansteuerung der Hydraulikpumpe durch eine besonders einfache elektronische Schaltung erfolgen.According to a preferred embodiment of the invention, the first rate of the additional pressure build-up is constant. Thus, the control of the hydraulic pump can be done by a particularly simple electronic circuit.
Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung ist die erste Rate des zusätzlichen Druckaufbaus davon abhängig, wie groß die Differenz zwischen dem momentanen Maß für die Bremsanforderung und dem ersten Schwellwert ist, insbesondere proportional zu dieser Differenz. Besteht erhöhter Bedarf an Bremsverzögerung, so kann eine erhöhte zusätzliche Bremskraft aufgebaut werden.According to a further preferred embodiment of the invention, the first rate of the additional pressure buildup is dependent on, in particular proportional to this difference, the difference between the instantaneous measure for the brake request and the first threshold value. If there is an increased need for deceleration, an increased additional braking force can be built up.
In einer besonders bevorzugten Ausführungsform der Erfindung wird überprüft, ob das Maß der Bremsanforderung einen zweiten Schwellwert überschreitet, und bei Überschreiten des zweiten Schwellwerts findet der Druckaufbau mittels der Hydraulikpumpe mit einer zweiten Rate statt, welche die erste Rate übersteigt, wobei insbesondere eine Erhöhung der Druckaufbaurate um einen konstanten Wert stattfindet. Wird eine Panikbremsung erkannt, so wird eine besonders starke zusätzliche Bremskraft durch die Hydraulikpumpe aufgebaut.In a particularly preferred embodiment of the invention, it is checked whether the measure of the brake request exceeds a second threshold value, and when the second threshold value is exceeded, the pressure buildup by means of the hydraulic pump takes place at a second rate which exceeds the first rate, wherein in particular an increase of the pressure build-up rate takes place at a constant value. If a panic braking is detected, a particularly strong additional braking force is built up by the hydraulic pump.
In einer ganz besonders bevorzugten Ausführungsform der Erfindung wird der zweite Schwellwert abhängig von der Fahrzeuggeschwindigkeit gewählt.In a very particularly preferred embodiment of the invention, the second threshold value is selected as a function of the vehicle speed.
Insbesondere wird in den Bereichen des Abfalls der typischen Generatorkennlinien bei Unterschreiten einer Minimalgeschwindigkeit und Überschreiten einer Maximalgeschwindigkeit, eine gegenüber dem Vorgehen bei mittleren Geschwindigkeiten erhöhte zweite Rate des Druckaufbaus gewählt, um das geringere elektrisch-regenerative Schleppmoment zu kompensieren.In particular, in the areas of waste of the typical generator characteristic curves falls below a minimum speed and exceeding a maximum speed, a increased second rate of pressure build-up chosen to compensate for the lower electric regenerative drag torque over the medium speed approach.
Zweckmäßigerweise findet bei ruhendem Fahrzeug unabhängig von dem Maß der Bremsanforderung kein zusätzlicher Druckaufbau mehr statt. Ein ruhendes Fahrzeug wird vorzugsweise daran erkannt, dass der Betrag aller Radgeschwindigkeiten einen vorgegebenen Schwellwert unterschreitet. Da der Bremsdruck für das Halten eines ruhenden Fahrzeugs allein durch die Fedalbetätigung des Fahrers erzeugt wird, kann der durch Aktivierung einer Hydraulikpumpe verursachte Energieverbrauch vermieden werden.Conveniently, no additional pressure build-up takes place when the vehicle is at rest, regardless of the extent of the braking request. A stationary vehicle is preferably recognized by the fact that the amount of all wheel speeds falls below a predetermined threshold. Since the brake pressure for holding a stationary vehicle is generated solely by the driver's Fedalbetätigung, the energy consumption caused by activation of a hydraulic pump can be avoided.
Bevorzugt findet der zusätzliche Druckaufbau nur in dem oder den Bremskreisen (I) statt, die einen teilweise gefüllten Druckspeicher (
Besonders bevorzugt wird nach Beendigung eines Bremsvorgangs, bei dem ein zusätzlicher Druckaufbau stattgefunden hat, der Druckspeicher (
In einer weiteren besonders bevorzugten Ausführungsform der Erfindung wird nach Beendigung eines Bremsvorgangs, bei dem ein zusätzlicher Druckaufbau stattgefunden hat, der Druckspeicher (
Die Erfindung betrifft ferner ein schlupfgeregeltes Bremssystem mit hydraulischen Reibbremsen in einem zumindest mit einem elektrischen Fahrzeugantrieb ausgestatteten Kraftfahrzeug, wobei der elektrische Fahrzeugantrieb als Generator verwendet werden kann, wobei sich das Gesamtbremsmoment an mindestens einer Achse zumindest zeitweise aus elektrisch-regenerativem Schleppmoment und Reibbremsmoment zusammensetzt, wobei das Bremssystem keinen pneumatischen Bremskraftverstärker aufweist. Erfindungsgemäß ist mindestens ein für den Druckabbau während einer Schlupfregelung vorhandener Bremsmittelspeicher (
Gemäß einer bevorzugten Ausführungsform der Erfindung kann der elektrische Fahrzeugantrieb im Generatorbetrieb entweder mit einem Energiespeicher oder mit einem elektrischen Verbraucher verbunden werden, insbesondere einem Heizwiderstand. Somit steht im Generatorbetrieb des elektrischen Fahrzeugantriebs unabhängig vom Füllstand des Energiespeichers ein gleichbleibendes Schleppmoment zur Verfügung. Dies gewährleistet ein gleichbleibendes Pedalgefühl, ohne dass ein aufwendiger Pedalsimulator vorhanden sein muss.According to a preferred embodiment of the invention, the electric vehicle drive can be connected in generator mode either with an energy store or with an electrical load, in particular a heating resistor. Thus, a constant drag torque is available in the generator mode of the electric vehicle drive regardless of the level of the energy storage available. This ensures a consistent pedal feel, without the need for a complex pedal simulator.
Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung werden die Räder mindestens einer Achse zeitweise mit einem mechanischen Energiewandler, vorzugsweise einem Retarder, verbunden. Eine vom Füllstand des Energiespeichers unabhängige Verzögerung des regenerativen Bremssystems lässt sich auch mit einer mechanischen Dauerbremse, wie einem Retarder sicherstellen. Daher kann auf einen Pedalsimulator verzichtet werden.According to a further preferred embodiment of the invention, the wheels of at least one axis are temporarily connected to a mechanical energy converter, preferably a retarder. An independent of the level of the energy storage delay of the regenerative braking system can be ensured with a mechanical retarder, such as a retarder. Therefore, it is possible to dispense with a pedal simulator.
Vorzugsweise sind die Ansaugseite der Hydraulikpumpe und das primäre Bremsdruckerzeugungsmittel nicht durch ein einzelnes stromlos geschlossenes Magnetventil hydraulisch verbunden. Das erfindungsgemäße Bremssystem weist somit eine minimale Anzahl von Ventilen auf.Preferably, the suction side of the hydraulic pump and the primary brake pressure generating means are not hydraulically connected by a single normally closed solenoid valve. The brake system according to the invention thus has a minimum number of valves.
Bevorzugt wird zumindest die Hydraulikpumpe (
Zweckmäßigerweise wird die Betriebsdauer der Hydraulikpumpe (
Es ist vorteilhaft, wenn die Hydraulikpumpe (
Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung weist jedes Rad mindestens einer Achse, insbesondere der Hinterachse, einen getrennten elektrischen Antrieb (
In einer besonders bevorzugten Ausführungsform der Erfindung erfolgt eine aktive Beeinflussung der Gierrate des Fahrzeugs durch eine gezielte Anforderung unterschiedlich hoher elektrisch-regenerativer Schleppmomente an den verschiedenen Rädern der Achse mit elektrischen Antrieben.In a particularly preferred embodiment of the invention, the yaw rate of the vehicle is actively influenced by a specific requirement of different high electric-regenerative drag torques at the various wheels of the axle with electric drives.
Gemäß einer alternativen besonders bevorzugten Ausführungsform der Erfindung erfolgt eine aktive Beeinflussung der Gierrate des Fahrzeugs, indem ein Rad der Achse mit elektrischen Antrieben elektrisch-regenerativ gebremst wird, während das zweite Rad der Achse elektrisch angetrieben wird.According to an alternative particularly preferred embodiment of the invention, the yaw rate of the vehicle is actively influenced by electrically-regeneratively braking a wheel of the axle with electric drives, while the second wheel of the axle is electrically driven.
Die Erfindung betrifft weiterhin die Verwendung eines erfindungsgemäßen Bremssystems in einem Kraftfahrzeug mit zwei oder drei Rädern. The invention further relates to the use of a brake system according to the invention in a motor vehicle with two or three wheels.
Durch eine geeignete Wahl der Schwelle für die Aktivierung der elektrischen Hydraulikpumpe wird diese selten aktiviert, weshalb eine kostengünstige Ausführung ausreichend ist. Eine weitere Einsparmöglichkeit ergibt sich, wenn ein Bremssystems ohne Fahrdynamikregelung gewählt wird, da somit keine aufwendigen Gierraten- und Beschleunigungssensoren benötigt werden.By a suitable choice of the threshold for the activation of the electric hydraulic pump, this is rarely activated, which is why a cost-effective design is sufficient. A further savings option results when a brake system without vehicle dynamics control is selected, since thus no complex yaw rate and acceleration sensors are needed.
Weitere bevorzugte Ausführungsformen ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung eines Ausführungsbeispiels an Hand von Figuren.Further preferred embodiments will become apparent from the subclaims and the following description of an embodiment with reference to figures.
