Die Idee der Erfindung zielt darauf ab Querkräfte der Räder, die zum Lenken erforderlich sind, durch Längskräfte der Räder zu ersetzen durch das Beschleunigen (d.h. auch Verzögern) einzelner angetriebener Räder. Dieses System müsste dann nicht mehr ein passives Sicherheitssystem sein, sondern könnte permanent aktiv sein und die gewünschte Lenkbewegungen des Fahrers unterstützen.The Invention describes a device for driving dynamics control, with the steering by an intervention in the drive power of individual Powered wheels supported by a coupling. On the wheels of a vehicle generally act on longitudinal forces to accelerate and decelerate and transverse forces for steering. The idea of the invention aims at lateral forces of Bikes, which are required for steering to replace by longitudinal forces of the wheels by accelerating (i.e., delaying) single driven wheels. This system would have to then no longer be a passive security system, but could be permanent be active and the desired Support steering movements of the driver.
Ein solcher Effekt wir schon genutzt von einem Motorradfahrer mit Beiwagen, der vor einer Linkskurve bremst und beim Ausfahren aus der Kurve wieder Gas gibt (umgekehrt bei Rechtskurven), oder beim Motorbootfahren mit zwei getrennten Motoren/Schrauben oder bei einem Kettenfahrzeug (Panzer), dass durch getrenntes Gasgeben gesteuert wird.One such effect we already used by a motorcyclist with sidecar, which brakes before a left turn and when extending out of the bend gas again (in reverse on right-handers), or motorboating with two separate motors / screws or with a tracked vehicle (tank), that is controlled by separate throttle giving.
Im Fall eines normalen Kfzs mit vier Reifen besteht das Problem, dass durch zu schnelles Einlenken vor allem auf glatter Fahrbahn es passieren kann, dass das Fahrzeug über die Lenkung schiebt, da die Querkräfte nicht ausreichen so schnell den Drehimpuls aufzubauen, wie die Lenkung den Lenkwinkel verändert. In diesem Falle könnte durch einen Eingriff in die Antriebsleistung durch eine Kupplung einzelner oder mehrerer Räder des Fahrzeugs die Veränderung des Drehimpulses unterstützt werden.in the Case of a normal car with four tires is the problem that by turning it too fast, especially on a slippery road, it can happen that the vehicle over the steering pushes, because the lateral forces are not sufficient so fast build up the angular momentum as the steering changes the steering angle. In this case could by an intervention in the drive power by a clutch individual or more wheels the vehicle's change supported the angular momentum become.
Zu jedem Wertepaar von Lenkwinkel und Geschwindigkeit gehört eine bestimmte Drehrate bei einem Fahrzeug. Stimmt die Soll-Drehrate und die Ist-Drehrate nicht in einem gewissen Rahmen überein, so hat das Fahrzeug einen großen Schräglaufwinkel an mindestens einem Rad und das Fahrzeug unter-/übersteuert. Das System kann nun getrennt in die Antriebsleistung einzelner Räder rechts/links des Fahrzeugs über eine Kupplung eingreifen, um die Drehrate (->Drehimpuls) dem Lenkwinkel und der Geschwindigkeit anzupassen. Zu geringe Querkräfte an den Reifen können so durch Längskräfte ersetzt werden. Der Fahrer gibt somit – mit der gewählten Geschwindigkeit und dem gewählten Lenkradeinschlag – eine gewünschte Drehrate des Fahrzeuges vor, das System versucht nun permanent eine Abweichung (Soll/Ist) ab einem bestimmten Wert zu korrigieren.To each value pair of steering angle and speed includes one certain rotation rate in a vehicle. Corresponds to the set rate of rotation and the actual yaw rate does not agree to a certain extent, so the vehicle has a big one Slip angle on at least one wheel and understeer / oversteer the vehicle. The system can now separated into the drive power of individual wheels right / left of the vehicle via a Clutch intervene to the rate of rotation (-> angular momentum) the steering angle and the speed adapt. Too little lateral forces the tire can be replaced by longitudinal forces. The driver is thus - with the selected speed and the chosen one Steering wheel - one desired Yaw rate of the vehicle before, the system is now permanently trying one Deviation (target / actual) from a certain value to correct.
Eine schnelle Bewegung am Lenkrad – gerade im Grenzbereich eines Fahrzeuges – kann ein Schleudern zur Folge haben, da die Querkräfte (aufgrund der Zentripetalkraft) nicht mehr ausreichen um den Drehimpuls des Fahrzeuges so schnell zu ändern. In diesem Fall greift das System in eine Kupplung ein um die Kräfte für die Drehimpulsänderung durch Längskräfte aufzubringen.A fast movement on the steering wheel - straight in the border area of a vehicle - can result in a spin have, because the lateral forces (due to the centripetal force) are no longer sufficient for the angular momentum to change the vehicle so quickly. In this case, the system intervenes in a clutch by the forces for the angular momentum change Apply longitudinal forces.
Von dem System kann als zusätzliche Information noch die Aufstandskraft (z.B. durch die Eintauchtiefe der Stoßdämpfer) der Räder sowie die Querbeschleunigung des Fahrzeuges benutzt werden. Durch eine geeignete Auswertung kann so ermittelt werden, welches Rad noch größere Längskräfte aufnehmen könnte. Bei geeigneter Regelung kann so sichergestellt werden, dass wenn das Fahrzeug aus der Kurve fliegt, auch wirklich alle Räder gleichzeitig die Bodenhaftung verloren haben und man definitiv den Grenzbereich überschritten hat.From The system can be as additional Information is still the Aufstandskraft (for example, by the immersion depth the shock absorber) the Wheels as well the lateral acceleration of the vehicle can be used. By a appropriate evaluation can be determined which wheel still absorb larger longitudinal forces could. With suitable control can be ensured so that if the vehicle flies out of the bend, really all the wheels at the same time have lost the grip and you definitely crossed the border Has.
Aufgabe der Erfindung ist es jedes Über-/Untersteuern des Fahrzeuges durch einen großen Schräglaufwinkel an den Rädern zu beseitigen. Vor allem bei schneeglatter Fahrbahn gibt der Fahrer mit dem Lenkrad (beim Schleudern) eine gewünschte Drehrate vor und das Fahrzeug stabilisiert sich wieder selber um diesen Wert, wodurch dem ungeübten Fahrer auch ein Gegenlenken erspart bleiben kann.task The invention is any over / understeer of the vehicle by a large slip angle at the wheels to eliminate. Especially when the slippery road surface gives the driver with the steering wheel (when spinning) a desired rate of rotation before and Vehicle stabilizes itself again by this value, which the inexperienced driver even a counter-steering can be spared.
