"Vorrichtung zum Bremsen""Braking device"
Beschreibung:Description:
Die vorliegende Erfindung betrifft eine Vorrichtung zum Brem¬ sen mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The present invention relates to a device for braking with the features of the preamble of patent claim 1.
In US-A 41 46 108 wird eine Vorrichtung zum Bremsen in einem Fahrzeug beschrieben. Zu der Vorrichtung gehört ein Bremssteu¬ ersystem, dem eine Erfassungseinrichtung mit einer einen dem Gaspedal des Fahrzeugs zugeordneten, ersten Sensor umfassen¬ den, ersten Sensoreinrichtung, zugeordnet wird. Der erste Sen¬ sor liefert bei einer reflexartigen Wegbewegung des rechten Fußes des Fahrers von einer ersten Stellung am Gaspedal zu ei¬ ner zweiten Stellung ein erstes Signal an die Erfassungsein¬ richtung. Im Bekannten wird abhängig vom Auftreten des von dem ersten Sensor erzeugten ersten Signals durch die Erfassungs¬ einrichtung ein Bremsvorgang automatisch ausgelöst.In US-A 41 46 108 a device for braking in a vehicle is described. The device includes a brake control system to which a detection device with a first sensor device comprising a first sensor assigned to the gas pedal of the vehicle is assigned. When the driver's right foot moves reflexively away from a first position on the accelerator pedal to a second position, the first sensor supplies a first signal to the detection device. In the known, depending on the occurrence of the first signal generated by the first sensor, a braking process is triggered automatically by the detection device.
Eine Weiterentwicklung des Bremssystems wird in der interna¬ tionalen Patentanmeldung WO 95/01898 beschrieben. Danach soll sichergestellt werden, daß nicht bei irgendeiner reflexartigen Bewegung des am Gaspedal stehenden Fahrerfußes das Fahrzeug bereits automatisch gebremst. Aus diesem Grunde soll der Bremsvorgang erst ausgelöst werden, wenn das erste Signal eine reflexartige Bewegung des Fahrerfußes anzeigt und wenn außer¬ dem ein weiteres Signal auftritt. Es kann sich hierbei entwe¬ der um ein zweites Signal handeln, das anzeigt, daß der Fah¬ rerfuß vom Gaspedal abgehoben ist, oder daß der Fahrerfuß sich vom Gaspedal in Richtung zum Bremspedal bewegt.A further development of the brake system is described in the international patent application WO 95/01898. Thereafter, it should be ensured that the vehicle is not automatically braked in the event of any reflex movement of the driver's foot standing on the accelerator pedal. For this reason, the braking process should only be triggered when the first signal indicates a reflex movement of the driver's foot and when a further signal also occurs. This can either be a second signal which indicates that the driver's foot has been lifted off the accelerator pedal, or that the driver's foot is moving from the accelerator pedal in the direction of the brake pedal.
Das bekannte Bremssteuersystem setzt voraus, daß das Gaspedal vor der Folge von Signalen bzw. Schritten überhaupt einge¬ drückt war. Hat nämlich der Fahrer den Fuß nur lose am Gaspe¬ dal liegen, so daß das Gaspedal nicht oder praktisch nicht eingedrückt wird, kann das erste Signal, das den Beginn einer reflexartigen Fußbewegung anzeigen und die Erfassungseinrich¬ tung aktivieren soll, gar nicht auftreten. Die Erfassungsein¬ richtung stellt dann vielleicht das zweite Signal fest, da¬ durch allein darf aber der panikartige bzw. automatische Bremsvorgang nicht ausgelöst werden.The known brake control system assumes that the accelerator pedal was depressed at all before the sequence of signals or steps. If the driver only has his foot loosely on the accelerator pedal so that the accelerator pedal is not or practically not depressed, the first signal which signals the start of a display reflex foot movement and activate the detection device, do not occur at all. The detection device may then determine the second signal, but this alone must not trigger the panic-like or automatic braking process.
Der Erfindung liegt die Aufgabe zugrunde, ein Mittel zu schaf¬ fen, mit dem es auch möglich ist, das erste Signal, das den Beginn der reflexartigen Fußbewegung anzeigen und die Erfas¬ sungseinrichtung aktivieren soll, auch dann auszulösen, wenn der Fuß vor der panikartigen Reflexbewegung nur lose am Gaspe¬ dal gelegen hat.The invention has for its object to provide a means with which it is also possible to trigger the first signal, which should indicate the start of the reflex-like foot movement and activate the detection device, even when the foot is in front of the panic-like one The reflex movement was only loosely on the gas pedal.
Die erfindungsgemäße Lösung besteht darin, daß der Position des Fahrerfußes am nicht eingedrückten Gaspedal ein eine ruck¬ artige Wegbewegung des Fußes erfassender Reflexfühler, der ein das erste Signal ersetzendes Hilfssignal an die Erfassungsein¬ richtung liefert, zugeordnet ist. Der Begriff "ruckartige Weg¬ bewegung" umfaßt eine panikartige Reflexbewegung (und umge¬ kehrt) .The solution according to the invention is that the position of the driver's foot on the accelerator pedal that is not depressed is associated with a reflex sensor that detects a jerky movement of the foot and that supplies an auxiliary signal to the detection device that replaces the first signal. The term "jerky path movement" includes a panic-like reflex movement (and vice versa).
Durch die Erfindung wird erreicht, daß ein erstes Signal, das die Erfassungseinrichtung aktiviert und damit die Automatik¬ bzw. Panik-Bremsung überhaupt möglich macht, in Form des vom Reflexfühler abgegebenen Hilfssignals auch dann zur Verfügung gestellt wird, wenn der Fahrer im Moment vor dem erforderlich werdenden Bremsen das Gaspedal gar nicht eingedrückt hatte. Voraussetzung für das Entstehen ist lediglich, daß der Fahrer¬ fuß zumindest in der Nähe des Gaspedals, nämlich so nahe an dem Pedal liegt, daß der Reflexfühler die ruckartige Wegbewe¬ gung des Fußes erfassen kann.The invention ensures that a first signal, which activates the detection device and thus makes automatic or panic braking possible at all, is made available in the form of the auxiliary signal emitted by the reflex sensor even if the driver is currently in front of the vehicle required brakes had not pressed the accelerator at all. The only requirement for the emergence is that the driver's foot is at least in the vicinity of the accelerator pedal, namely so close to the pedal that the reflex sensor can record the jerky movement of the foot.
Vorzugsweise soll der Reflexfühler auch in der Lage sein, zu¬ mindest einen geringen Weg einer Reflexbewegung des Fußes zu erfassen, denn es interessiert ja die Geschwindigkeit mit der der Fuß weggezogen wird und nicht allein die Anwesenheit des Fußes an der Meßstelle. Gemäß weiterer Erfindung wird als Reflexfühler ein federbe¬ lasteter Taster auf der Trittfläche des Gaspedals vorgesehen, wobei die Rückstellkraft der beim Betätigen des Tasters einzu¬ drückenden Tasterfeder klein gegen die Rückstellkraft der beim Betätigen des Gaspedals einzudrückenden Hauptfeder sein soll. Dadurch wird erreicht, daß der Taster mit einer minimalen, kaum merklichen Kraft, die nicht ermüdet, ständig einzudrücken ist. Das zum Aktivieren der Erfassungseinrichtung erforderli¬ che erste Signal steht dann in Form des Hilfssignals auch zur Verfügung, wenn vor Beginn der plötzlich erforderlich werden¬ den Bremsung gar kein Gas gegeben wurde.Preferably, the reflex sensor should also be able to detect at least a small path of a reflex movement of the foot, because the speed at which the foot is pulled away is of interest, and not only the presence of the foot at the measuring point. According to another invention, a spring-loaded button is provided as a reflex sensor on the tread of the accelerator pedal, the restoring force of the button spring to be pressed when the button is pressed against the restoring force of the main spring to be pressed when the accelerator pedal is pressed. The result of this is that the push button must be pressed in continuously with a minimal, barely noticeable force which does not tire. The first signal required to activate the detection device is also available in the form of the auxiliary signal if no gas was given at all before the braking suddenly required.
Ein auf der Trittfläche des Gaspedals vorgesehene Taster kann vorzugsweise als kleines, um eine Achse schwenkbares Pedal (innerhalb des Hauptpedalkörpers oder auf dessen Trittfläche) ausgebildet sein. Diesem kleinen Pedal oder Hilfspedal kann eine mechanische Feder zugeordnet werden, die schon bei leich¬ ter Berührung des (kleinen) Pedals mit dem Fuß in Richtung auf die Trittfläche des Hauptpedals eingedrückt wird.A button provided on the tread of the accelerator pedal can preferably be designed as a small pedal that can be pivoted about an axis (inside the main pedal body or on its tread). A mechanical spring can be assigned to this small pedal or auxiliary pedal, which is pressed in when the (small) pedal is lightly touched by the foot in the direction of the step surface of the main pedal.
Gemäß weiterer Erfindung wird gegebenenfalls die mechanische Feder des Hilfspedals mit einem Wegmeßfühler, dem erfindungs¬ gemäßen Reflexfühler, ausgestattet. Der Reflexfühler soll die Geschwindigkeit registrieren, mit der der Fuß gegebenenfalls vom Gaspedal bzw. von dem Hilfspedal abgehoben wird. Erfüllt die Abhebegeschwindigkeit die Voraussetzungen für das Entste¬ hen des ersten Signals, wird dadurch die Erfassungseinrichtung für den Empfang eines zweiten Signals aktiviert. Damit wird beim Eingang des zweiten Signals der Bremsvorgang - wie im Be¬ kannten - sofort - also schon vor dem Auftreffen des Fußes auf dem Bremspedal - ausgelöst.According to another invention, the mechanical spring of the auxiliary pedal is optionally equipped with a displacement sensor, the reflex sensor according to the invention. The reflex sensor should register the speed at which the foot may be lifted off the accelerator pedal or the auxiliary pedal. If the take-off speed meets the requirements for the creation of the first signal, the detection device is activated for the reception of a second signal. Thus, when the second signal is received, the braking process - as in the known one - is triggered immediately - that is, even before the foot hits the brake pedal.
Gemäß weiterer Erfindung kann der Reflexfühler auch als Licht¬ schranken-Einrichtung oder dergleichen kontaktlosen Mitteln ausgebildet werden. Es kommt ja erfindungsgemäß nur darauf an, festzustellen, ob eine reflexartige oder ruckartige Bewegung des Fußes aus dem Bereich des Gaspedals in Richtung auf das Bremspedal beginnt, und die Erfassungseinrichtung gegebenen- falls entsprechend zu aktivieren. According to a further invention, the reflex sensor can also be designed as a light barrier device or similar contactless means. It is only important according to the invention to determine whether a reflex or jerky movement of the foot begins from the area of the accelerator pedal in the direction of the brake pedal, and the detection device, if applicable, if necessary to activate accordingly.
Anhand der schematischen Darstellung von Ausführungsbeispielen werden Einzelheiten der Erfindung erläutert. Es zeigen:Details of the invention are explained on the basis of the schematic representation of exemplary embodiments. Show it:
Fig. 1 ein Gaspedal mit einem Hilfspedal; und Fig. 2 ein Gaspedal mit kontaktlosem Reflextaster.1 shows an accelerator pedal with an auxiliary pedal; and FIG. 2 shows an accelerator pedal with a contactless reflex sensor.
Die symbolische Darstellung in Fig. 1 zeigt ein insgesamt mit 1 bezeichnetes Gaspedal, dessen Schwenkachse 2 eine Pedalrück¬ stellfeder 3 mit der Federkonstanten Rl zugeordnet ist. Mit der Achse 2 bzw. der Feder 3 wird gemäß eingangs genannter WO 95/01898 ein Reflexfühler zum Liefern eines ersten Signals, das eine Erfassungseinrichtung aktiviert, gekoppelt. Ersicht¬ lich kann dieses erste Signal nur erzeugt werden, wenn das Pe¬ dal 1 eingedrückt war. Das Gaspedal 1 wird am oberen Ende an einem Befestigungspunkt 4 mit einem Gas-Zugseil 5 verbunden. Am unteren Ende weist das Gaspedal 1 einen Pedalkörper 6 mit dem Fahrerfuß zugewandter Trittfläche 7 auf.The symbolic representation in FIG. 1 shows an accelerator pedal, designated overall by 1, whose pivot axis 2 is associated with a pedal return spring 3 with the spring constant R1. A reflex sensor for supplying a first signal, which activates a detection device, is coupled to the axis 2 or the spring 3 in accordance with the aforementioned WO 95/01898. Obviously, this first signal can only be generated if the pedal 1 was pressed in. The accelerator pedal 1 is connected at the upper end to a fastening point 4 with a throttle cable 5. At the lower end, the accelerator pedal 1 has a pedal body 6 with the tread 7 facing the driver's foot.
Im Ausführungsbeispiel nach Fig. 1 wird in die Trittfläche 7 ein Hilfspedal 8 integriert, das durch Eindrücken einer Ta¬ sterfeder 9 mit der Federkonstanten R2 an die Trittfläche 7 heranzudrücken ist. R2 soll klein gegen Rl sein. Das Hilfspe¬ dal 8 kann auf irgendeine Weise, z.B. durch Anlenken an eine der Trittfläche 7 zugeordnete Achse 10 beweglich am Pedalkör¬ per 6 befestigt werden. Es läßt sich auch als lediglich mit der Feder 9 gekoppelter Tasterkörper ausbilden. Das Hilfspedal 8 bzw. der Taster können auch eingedrückt sein, ohne daß Gas gegeben wird, also ohne daß das Gaspedal 1 betätigt wird.In the exemplary embodiment according to FIG. 1, an auxiliary pedal 8 is integrated into the tread surface 7, which can be pressed against the tread surface 7 by pressing in a key spring 9 with the spring constant R2. R2 should be small against Rl. The auxiliary pedal 8 can be operated in any way, e.g. can be movably attached to the pedal body 6 by articulation on an axis 10 assigned to the step surface 7. It can also be designed as a push button body coupled only with the spring 9. The auxiliary pedal 8 or the button can also be pressed in without accelerating, that is, without the accelerator pedal 1 being actuated.
Erfindungsgemäß wird dem Hilfspedal 8 bzw. der Tasterfeder 9 ein Reflexfühler 11 zugeordnet. Dieser soll in der Lage sein festzustellen, ob das Hilfspedal 8 gegebenenfalls gegen die Federkraft R2 eindrückende Fahrerfuß mit üblicher Geschwindig¬ keit oder ruckhaft bzw. reflexartig von einer Position am Pe¬ dalkörper 6 weg bewegt bzw. abgehoben wird.According to the invention, the auxiliary pedal 8 or the key spring 9 is assigned a reflex sensor 11. The latter should be able to determine whether the auxiliary pedal 8, if applicable, the driver's foot pressing in against the spring force R2 is moved or lifted away from a position on the pedal body 6 at a normal speed or in a jerky or reflex manner.
In einem in Fig. 2 symbolisch dargestellten zweiten Ausfüh¬ rungsbeispiel wird zum Erfassen des beschriebenen Hilfs- bzw. Reflexsignals nicht ein mechanischer Taster, sondern ein kon¬ taktlos arbeitender Reflexfühler vorgesehen. Hierzu werden ne¬ ben dem Pedalkörper 6, etwa auf der Höhe des am oder in der Nähe des Pedalkörpers 6 befindlichen Fahrerfußes, kontaktlose Sender bzw. Empfänger 12 positioniert, die feststellen können, ob der Fahrerfuß mit normaler Geschwindigkeit oder ruckartig bzw. reflexartig von dem Pedalkörper 6 weg bewegt wird. Die Sender und Empfänger 12 sollen bei reflexartig erfolgender Wegbewegung ein (das erste Signal ersetzendes) Hilfssignal an die Erfassungseinrichtung geben und letztere damit für den Empfang eines zweiten Signals aktivieren.In a second exemplary embodiment shown symbolically in FIG. 2, in order to capture the described auxiliary or Reflex signal not a mechanical button, but a contactless reflex sensor is provided. For this purpose, contactless transmitters or receivers 12 are positioned next to the pedal body 6, for example at the level of the driver's foot located on or in the vicinity of the pedal body 6, which can determine whether the driver's foot is moving at normal speed or jerkily or reflexively Pedal body 6 is moved away. The transmitters and receivers 12 are to give an auxiliary signal (replacing the first signal) to the detection device in the event of a reflex movement and thus activate the detection device for the reception of a second signal.
Es wird eine Vorrichtung zum Bremsen eines Fahrzeugs mit einem Panik-Bremssteuersystem beschrieben, wobei dem Bremssteuersy¬ stem eine Erfassungseinrichtung zum Feststellen der Position des Fahrerfußes zugeordnet ist, derart, daß bei einer reflex¬ artig schnellen Bewegung des Fahrerfußes von einer ersten Stellung in eine zweite Stellung die Erfassungseinrichtung das Fahrzeug automatisch über ein Bremssteuersystem abbremst. Er¬ findungsgemäß wird ein reflexartiger Beginn der Bewegung des Fahrerfußes aus einer nicht eingedrückten Position am Gaspedal mit Hilfe eines Reflexfühlers erfaßt. A device for braking a vehicle with a panic brake control system is described, the brake control system being assigned a detection device for determining the position of the driver's foot, such that when the driver's foot moves reflexively and rapidly from a first position to a second Position the detection device automatically brakes the vehicle via a brake control system. According to the invention, a reflex-like start of the movement of the driver's foot from an unpressed position on the accelerator pedal is detected with the aid of a reflex sensor.
