Abstract

The system automatically restricts the speed of a vehicle negotiating a curve to a safe level. It uses the centrifugal force arising during the cornering movement to create a braking effect. A spring (2) holds the offside front wheel (1) and the axle in the normal position up to a given adhesion value; on exceeding the value the spring is compressed to release a switch (3) such that the current to the drive motor is diverted via a resistance (4), causing the motor speed to drop and hence the vehicle speed. USE/ADVANTAGE - Simple method for avoiding loss of control on curves in a vehicle with electric drive and no clutch.

Description

Anwendungsgebietfield of use

Die Erfindung kann eingesetzt werden bei allen Fahrzeugen mit lenkbaren Vorderrädern.The invention can be used with all Vehicles with steerable front wheels.

Zweckpurpose

Fahrzeuge sollen auch bei schneller Fahrt sicher auf der vorgesehenen Fahrbahn verbleiben auch wenn der Fahrzeugführer die Geschwindigkeit oder den Kurvenradius falsch einschätzt.Vehicles should be safe even when driving fast also remain on the intended lane when the driver's speed or misjudges the curve radius.

Stand der TechnikState of the art

Um ein Fahrzeug bei Kurvenfahrten sicher auf der vorgesehenen Fahrspur zu halten, hat der Fahrzeugführer Geschwindigkeit und Kurvenradius richtig einzuschätzen und sein Verhalten darauf abzustimmen.To keep a vehicle safe when cornering to keep the intended lane Driver speed and curve radius correctly assess and his behavior on it vote.

Kritik am Stand der TechnikCriticism of the state of the art

Wird die Kurve zu schnell oder zu eng gefahren, besteht die Gefahr, daß das Fahrzeug über die Vorderräder ausbricht und in ein unkontrollier­ bares Schleudern gerät. Der Fahrer erhält durch die vorhandene Technik keine ausreichende Unter­ stützung zur Vermeidung solcher Fahrfehler.If the curve is driven too fast or too tight, there is a risk that the vehicle over the Front wheels break out and into an uncontrolled hard skidding device. The driver gets through the existing technology is not a sufficient sub support to avoid such driving errors.

Aufgabetask

Der Erfindung liegt das Ziel zugrunde, durch eine vom Verhalten des Fahrers unbeeinflußte Auto­ matik einen solchen Fahrfehler so abzumindern, daß das Fahrzeug entsprechend abgebremst und damit in der vorgesehenen Fahrspur gehalten wird.The invention is based on the aim of Car unaffected by driver behavior to mitigate such a driving error that the vehicle is braked accordingly and thus kept in the intended lane becomes.

Lösungsolution

Diese Aufgabe wird mit dieser Erfindung dadurch gelöst, daß die bei Kurvenfahrten auftretende Fliehkraft des Fahrzeugs und die durch die Haftung des äußeren Vorderrades erzeugte Kraft gemessen wird. This object is achieved with this invention solved that the occurring when cornering Centrifugal force of the vehicle and by the Front wheel adhesion force created is measured.  

noch Lösungstill solution

Bei Überschreiten der vorgesehenen Kraft wird durch eine automatisch ausgelöste Schaltung die Antriebskraft auf die Antriebsräder ver­ mindert und so das Fahrzeug entsprechend ab­ gebremst. Diese Schaltung erfolgt unabhängig vom Fehlverhalten des Fahrers, er kann diesen Schaltvorgang nur durch entsprechend richtiges Verhalten vor der Kurve vermeiden.If the intended force is exceeded through an automatically triggered circuit ver the driving force on the drive wheels reduces and so the vehicle accordingly slowed down. This circuit is independent of the driver's misconduct, he can do it Switching process only by appropriately correct Avoid behavior in front of the curve.

Das hier vorgestellte Modell basiert auf einem Elektroantrieb ohne Kupplung. Die Verminderung des Fahrstromes wird durch die Zwischenschaltung eines Widerstandes erreicht; durch den direkten Antrieb führt die Verminderung der Motordrehzahl zu einer Abbremsung der Antriebsräder.The model presented here is based on a Electric drive without clutch. The diminution the traction current is through the intermediary resistance reached; through the direct The drive leads to a reduction in engine speed to brake the drive wheels.

Die Schaltung wird ausgelöst durch die in der seitlichen Führung beweglich aufgehängten Vorder­ achse. Wenn der hier auftretende Druck die Spannkraft der eingebauten Feder überschreitet wird der Schalter ausgelöst, der den Stromfluß über den Widerstand leitet und damit die An­ triebsspannung vermindert.The circuit is triggered by the in the side guide movable suspended front axis. If the pressure that occurs here Tension of the installed spring exceeds the switch that triggers the current flow is triggered leads over the resistance and thus the An drive voltage reduced.

Weitere AusgestaltungFurther configuration

Durch eine weitere Ausbildung dem Erfindung ist sicherzustellen, daß bei anderen Antriebsarten die durch die Schaltung ausgelöste Bremswirkung nicht, z. B. durch Auslösen der Kupplung etc. unterbrochen werden kann. Damit wird die Er­ findung für alle Antriebsarten verwendbar.Through further training the invention ensure that other types of drives the braking effect triggered by the circuit not, e.g. B. by releasing the clutch etc. can be interrupted. So that he can be used for all drive types.

Erzielbare VorteileAchievable advantages

Durch diese automatisch ausgelöste Schaltung kann ein vom Fahrer verursachter Fahrfehler vermindert und damit z. B. ein Ausbrechen oder Untersteuern des Fahrzeugs verhindert oder zumindest ver­ mindert werden. Das sonst gegebene Unfall- oder/ und Schadensrisiko wird damit reduziert. Through this automatically triggered circuit can a driver error caused by the driver is reduced and thus z. B. breakout or understeer of the vehicle prevented or at least ver be reduced. The otherwise given accident or / and damage risk is reduced.

Darstellung 1Illustration 1

Fahrzeug bei Geradeausfahrt, Bremsschaltung nicht ausgelöst.Vehicle when driving straight ahead, brake circuit not triggered.

Bei der Geradeausfahrt drückt die Feder (2) das Vorderrad (1) nach außen und entlastet damit den Schalter (3), der Motor erhält die durch den Fahrtregler bestimmte An­ triebsenergie.When driving straight ahead, the spring ( 2 ) presses the front wheel ( 1 ) outwards and thus relieves the switch ( 3 ), the motor receives the drive energy determined by the cruise control.

Fahrzeug bei Kurvenfahrt, Bremsschaltung ausgelöst.Vehicle when cornering, brake circuit triggered.

Bei der Kurvenfahrt hält die Feder (2) das äußere Vorderrad (1) und die Achse bis zu einem bestimmten Druck in Normalposition. Bei Überschreiten eines vorgegebenen Wertes wird die Feder durch die hereindrückende Achse soweit zusammengedrückt, daß ein Schalter (3) ausgelöst und damit die Strom­ zufuhr zum Antriebsmotor über einen Wider­ stand (4) geleitet wird. Durch diese Redu­ zierung der Stromzufuhr wird die Motor­ drehzahl vermindert und damit das Fahrzeug abgebremst.When cornering, the spring ( 2 ) holds the outer front wheel ( 1 ) and the axle in the normal position up to a certain pressure. When a predetermined value is exceeded, the spring is compressed by the pushing-in axis to such an extent that a switch ( 3 ) is triggered and the current supply to the drive motor is passed through a counter ( 4 ). By reducing the power supply, the engine speed is reduced and the vehicle is braked.
