Abstract

The vehicle (13) has an electrically operated stationary brake (2), controlled by signals from distance sensors (12,14) for obstacles at the front and rear of the vehicle, via a brake control (S) in response to the traffic situation. The brake control can provide automatic release of the stationary brake upon operation of the gas pedal (5) when the distance sensors indicate a free space to the front and/or rear of the vehicle.

Description

Die Erfindung betrifft ein Fahrzeug mit elektrisch betätigbarer Bremse gemäß Oberbegriff des Anspruchs 1.The invention relates to a vehicle with an electrically actuated brake according to Preamble of claim 1.

Es ist grundsätzlich bekannt, die Bremse eines Fahrzeugs über eine elektrische Steuerung betätigen zu können. So kann beispielsweise bei Schienenfahrzeugen ein Bremsvorgang elektrisch ausgelöst werden, wenn das Fahrzeug ein Haltesignal überfährt.It is basically known to brake a vehicle via an electric one To be able to operate the control. For example, in rail vehicles Braking is triggered electrically when the vehicle has a stop signal runs over.

Weiterhin ist es beispielsweise aus der DE 196 46 375 A1 bekannt, Kraftfahrzeuge mit Parkhilfesystemen auszurüsten, die mittels Abstandssensoren den Abstand zu benachbarten Hindernissen oder Fahrzeugen ermitteln und anzeigen können.Furthermore, it is known, for example from DE 196 46 375 A1, to use motor vehicles Equip parking assistance systems that use distance sensors to measure the distance identify and display neighboring obstacles or vehicles.

Der Erfindung liegt die Aufgabe zugrunde, ein Fahrzeug mit elektrisch betätigbarer Bremse derart auszubilden, daß bei stehendem Verkehr ein unbeabsichtigtes Weiterrollen des Fahrzeugs vermieden wird.The invention has for its object a vehicle with an electrically actuated Train the brake so that when the traffic is stationary an unintentional Rolling of the vehicle is avoided.

Die Lösung dieser Aufgabe erhält man mit den im Anspruch 1 aufgeführten Merkmalen. Das Fahrzeug ist erfindungsgemäß mit einer elektrisch betätigbaren Feststellbremse ausgerüstet, die in Abhängigkeit von der jeweiligen Verkehrssituation über eine Steuerung betätigt wird. Die Feststellbremse kann natürlich auch vom Fahrer manuell betätigt werden, jedoch führt die Steuerung in bestimmten Verkehrssituationen eine automatische Betätigung der Feststellbremse durch. Die elektrisch betätigbare Feststellbremse wird insbesondere bei einem Verkehrsstau auf einer Gefällstrecke so lange aktiviert, bis der Fahrer das Gaspedal betätigt und ein ausreichend großer Abstand in der beabsichtigten Fahrtrichtung zu anderen Fahrzeugen von Abstandssensoren ermittelt wird. Für den Fahrer ist es insbesondere eine große Erleichterung, nicht ständig auf der Fußbremse stehen zu müssen, um ein Weiterrollen des Fahrzeugs zu vermeiden, da die Steuerung in Verbindung mit der elektrisch betätigbaren Feststellbremse das Fahrzeug gegen Weiterrollen automatisch sichert. The solution to this problem is obtained with the features listed in claim 1. The vehicle is according to the invention with an electrically actuated parking brake equipped, depending on the respective traffic situation over a Control is operated. The parking brake can of course also be operated manually by the driver are operated, however, the control introduces in certain traffic situations automatic actuation of the parking brake. The electrically operated Parking brake is particularly so when there is a traffic jam on a downhill stretch activated for a long time until the driver depresses the accelerator and a sufficiently large distance in the intended direction of travel to other vehicles from distance sensors is determined. It is a great relief for the driver in particular, not all the time to have to stand on the foot brake to keep the vehicle rolling Avoid, since the control in connection with the electrically operated Parking brake automatically secures the vehicle against rolling.  

Das Vorhandensein einer Gefällstrecke läßt sich einfach mittels wenigstens eines Neigungssensors feststellen, der ebenso wie die Abstandssensoren an die Steuerung zur Betätigung der Feststellbremse angeschlossen ist.The presence of a downhill gradient can be easily determined using at least one Determine the inclination sensor, as well as the distance sensors to the control is connected to actuate the parking brake.

Die Steuerung kann in Verbindung mit den Abstandssensoren die Verkehrssituation "Stau" erkennen und bei Stillstand des Fahrzeugs die Feststellbremse aktivieren. In einer solchen Stausituation, bei der sich auch hinter dem Fahrzeug wenigstens ein weiteres Fahrzeug befindet, können die Bremsleuchten in ihrer Leuchtstärke mittels einer Intensitätssteuerung reduziert werden. Dadurch wird erreicht, daß ein hinter dem Fahrzeug haltender Fahrer nicht unnötig mit extrem hellen Bremsleuchten belästigt wird.In conjunction with the distance sensors, the controller can control the traffic situation Detect "traffic jam" and activate the parking brake when the vehicle is stationary. In a such a congestion situation in which there is at least one more behind the vehicle Vehicle is located, the brake lights in their luminosity by means of a Intensity control can be reduced. This ensures that a behind the Driver holding the vehicle is not unnecessarily bothered by extremely bright brake lights.

Die an die Steuerung angeschlossenen Abstandssensoren sind vorzugsweise Nahbereichs-Radarsensoren, die Teil eines Parkhilfesystems bzw. Nahbereichssensorik für eine automatische Distanzregelung sein können. Durch die Mitbenutzung der ohnehin bei einem Parkhilfesystem vorhandenen Abstandssensoren läßt sich der Mehraufwand für die Realisierung der elektrisch betätigbaren Feststellbremse sehr gering halten.The distance sensors connected to the controller are preferred Short-range radar sensors that are part of a parking aid system or short-range sensor system for an automatic distance control. By sharing the anyway With a parking sensor system existing distance sensors can the additional effort keep very low for the realization of the electrically operated parking brake.

Besonders vorteilhaft ist es, über die Abstandssensoren ein zu dicht auffahrendes Fahrzeug auch im fließenden Verkehr zu erkennen und am Heck des Fahrzeugs ggf. ein optisches Abstandswarnsignal zu aktivieren. Für das Abstandswarnsignal ist vorzugsweise eine zusätzliche Signalleuchte am Heck des Fahrzeugs angebracht, damit der Fahrer des zu dicht auffahrenden Fahrzeugs das Abstandswarnsignal auch eindeutig als solches erkennen kann und Fehlinterpretationen vermieden werden.It is particularly advantageous to use the distance sensors to drive up too closely Vehicle can also be recognized in flowing traffic and, if necessary, at the rear of the vehicle to activate the optical distance warning signal. For the distance warning signal is preferably an additional signal lamp attached to the rear of the vehicle so that the driver of the vehicle that is approaching too closely also clearly signals the distance warning signal can be recognized as such and misinterpretations avoided.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is illustrated below with the aid of one in the drawing Embodiment explained in more detail.

Die Zeichnung zeigt ein Blockschaltbild mit einer Steuerung S, die mit dem Bremssystem 1 des Fahrzeugs und mit einer elektrisch betätigbaren Feststellbremse 2 zusammenwirkt. Das Bremssystem 1 kann mit einem Antiblockiersystem (ABS) ausgerüstet sein. Die elektrische Feststellbremse 2 wird von der Steuerung S beispielsweise bei Betätigung eines Handbremshebels 3 oder automatisch in Abhängigkeit von der jeweiligen Verkehrssituation aktiviert. An die Steuerung S sind außerdem ein Bremspedal 4, das Gaspedal 5 ein Sitzbelegungssensor 6, ein Neigungssensor 7, eine Abstandselektronik 8 und eine Intensitätssteuerung 9 angeschlossen. Die Intensitätssteuerung ist ausgangsseitig mit Bremsleuchten 10, 11 verbunden, die sich ebenso wie rückwärtige Abstandssensoren 12 am Heck eines hier nur mit unterbrochener Linie angedeuteten Fahrzeugs 13 befinden. Vorne am Fahrzeug 13 können weitere Abstandssensoren 14 angeordnet sein, um auch den Abstand zu vor dem Fahrzeug 13 befindlichen Fahrzeugen bestimmen zu können. Die Abstandssensoren 12, 14 sind an die Abstandselektronik 8 angeschlossen, die an die Steuerung S den jeweiligen Abstand von vor und hinter dem Fahrzeug 13 befindlichen Fahrzeugen meldet.The drawing shows a block diagram with a controller S, which interacts with the brake system 1 of the vehicle and with an electrically actuated parking brake 2 . The brake system 1 can be equipped with an anti-lock braking system (ABS). The electric parking brake 2 is activated by the control S, for example when a handbrake lever 3 is actuated or automatically depending on the respective traffic situation. A brake pedal 4 , the accelerator pedal 5, a seat occupancy sensor 6 , an inclination sensor 7 , distance electronics 8 and an intensity control 9 are also connected to the control S. On the output side, the intensity control is connected to brake lights 10 , 11 , which, like rear distance sensors 12, are located at the rear of a vehicle 13 , which is only indicated here by a broken line. The front of the vehicle 13 more distance sensors 14 may be arranged to also be able to determine the distance to ahead of the vehicle 13 vehicles. The distance sensors 12 , 14 are connected to the distance electronics 8 , which reports to the controller S the respective distance from vehicles in front and behind the vehicle 13 .

Erkennt die Steuerung S des Fahrzeugs 13, daß sich das Fahrzeug im Stillstand befindet, kann die Steuerung S die elektrische Feststellbremse 2 so lange aktivieren, bis der Fahrer das Gaspedal 5 betätigt. Dabei kann die Steuerung S auch prüfen, ob überhaupt ein ausreichender Abstand zu benachbarten Fahrzeugen in der gewünschten Fahrtrichtung besteht. Sollte dies nicht der Fall sein, so kann die Steuerung S trotz Betätigung des Gaspedals 5 weiterhin die Feststellbremse 2 im Aktivzustand belassen.If the control S of the vehicle 13 recognizes that the vehicle is at a standstill, the control S can activate the electric parking brake 2 until the driver operates the accelerator pedal 5 . The control S can also check whether there is a sufficient distance from neighboring vehicles in the desired direction of travel. If this is not the case, the control S can continue to leave the parking brake 2 in the active state despite actuation of the accelerator pedal 5 .

Ein Sitzbelegungssensor 6 im Fahrersitz meldet an die Steuerung S, ob der Fahrersitz belegt oder nicht belegt ist. Bei Nichtbelegung des Fahrersitzes hält die Steuerung S die Feststellbremse 2 im angezogenen bzw. aktivierten Zustand.A seat occupancy sensor 6 in the driver's seat reports to the controller S whether the driver's seat is occupied or not. If the driver's seat is not occupied, the control S keeps the parking brake 2 in the applied or activated state.

In Verbindung mit dem an die Steuerung S angeschlossenen Neigungssensor 7 erkennt die Steuerung S, ob das Fahrzeug 13 sich auf einem Gefälle befindet. Melden die Abstandssensoren 12, 14 entsprechend geringe Abstände zu in der Nähe befindlichen Fahrzeugen oder Hindernissen, wird über die Steuerung S die Feststellbremse 2 aktiviert, um ein unbeabsichtigtes Auffahren des Fahrzeugs 13 auf ein Hindernis oder ein anderes Fahrzeug zu vermeiden.In conjunction with the inclination sensor 7 connected to the control S, the control S recognizes whether the vehicle 13 is on a slope. If the distance sensors 12 , 14 report correspondingly short distances to nearby vehicles or obstacles, the parking brake 2 is activated via the control S in order to avoid unintentional collision of the vehicle 13 with an obstacle or another vehicle.

Die Steuerung S erkennt in an sich bekannter Weise, ob das Fahrzeug 13 fährt oder still steht. Bei Stillstand des Fahrzeugs 13 und bei betätigtem Bremspedal 4 werden über die Intensitätssteuerung 9 die Bremsleuchten 10, 11 in ihrer zeitlich verzögerten Leuchtstärke reduziert, wenn die Abstandssensoren 12 gleichzeitig feststellen, daß sich hinter dem Fahrzeug 13 ein nachfolgendes, stehendes Fahrzeug befindet. Der Fahrer des hinter dem Fahrzeug 13 stehenden Fahrzeugs wird somit nur mit einer als angenehmer empfundenen reduzierten Leuchtstärke von den Bremsleuchten 10, 11 angestrahlt.The controller S recognizes in a manner known per se whether the vehicle 13 is traveling or is stationary. When the vehicle 13 is stationary and the brake pedal 4 is actuated, the brake lights 10 , 11 are reduced in their time-delayed luminosity via the intensity control 9 when the distance sensors 12 simultaneously determine that there is a following, stationary vehicle behind the vehicle 13 . The driver of the vehicle standing behind the vehicle 13 is therefore only illuminated by the brake lights 10 , 11 with a reduced luminosity which is perceived as more pleasant.

Die Abstandselektronik 8 ist Teil eines Parkhilfesystems, welches eine automatische Distanzregelung beinhalten kann. The distance electronics 8 is part of a parking aid system, which can include an automatic distance control.
