Abstract
(DE)
Die Erfindung betrifft ein dreirädriges Elektrofahrzeug nach EG-Fahrzeugklasse L2e-U, das zwei elektromotorisch angetriebene Hinterräder (100 und 100') hat, die je von einem, als mehrphasiger Synchronmotor mit integrierter Motorsteuerung ausgebildeten Radnabenmotor angetrieben werden, der für eine maximale Nenndauerleistung größer 2 kW und kleiner 6 kW ausgelegt ist, insbesondere für eine maximale Nenndauerleistung von etwa 4 kW ausgelegt ist. Am Vorderende der Fahrzeugkarosserie (3) ist eine Teleskopfedergabel (80) schwenkbar angelenkt, die gegenüber der Fahrzeuglängsrichtung einen maximalen Lenkwinkeleinschlag von etwa minus 80° bis etwa plus 80° auszuführen vermag, der von einem Lenkwinkelsensor erfasst wird, der ein entsprechendes Lenkwinkelsignal erzeugt. Ferner ist am Fahrzeug (2) ein, mit Datenspeicherkapazität und digitaler Datenverarbeitungskapazität ausgerüsteter Controller montiert, der die beiden Motorsteuerungen so ansteuert, dass bei einer Kurvenfahrt die beiden Antriebsräder (100 und 100') mit je unterschiedlichem Drehmoment betrieben werden. Beispielsweise kann der Controller einen Anfahr- und Hindernisüberwindungs-Modus veranlassen, der bei einer Fahrzeuggeschwindigkeit von 0 bis 2 km/h ausgeführt wird, wobei bei einem starken Lenkwinkeleinschlag bis zu 80° der am kurvenäußeren Rad montierte Motor etwa 90 % des mit der gegebenen Beschleunigungsdrehgriff-Stellung angeforderten Gesamt-Drehmoments liefert, und der am kurveninneren Rad montierte Motor etwa 10 % des angeforderten Gesamt-Drehmoments liefert, das heißt ein Drehmomentverhältnis von 90 zu 10 eingestellt wird. Bei einem geringeren Lenkeinschlag wird ein proportional entsprechend vermindertes Drehmomentverhältnis eingestellt, bis bei Geradeausfahrt ein solches Drehmomentverhältnis von 50 zu 50 erreicht ist.
(EN)
The invention relates to a three-wheeled electric vehicle according to the EU vehicle class L2e-U which has two rear wheels (100 and 100') which are driven electromotively and are each driven by a wheel hub motor which is embodied as a multi-phase synchronous motor with an integrated motor controller and is configured for a maximum continuous rated power of greater than 2 kW and less than 6 kW, in particular for a maximum continuous rated power of approximately 4 kW. A telescopic spring fork (80) is pivotably coupled to the front end of the vehicle bodywork (3) and is capable of executing, with respect to the longitudinal direction of the vehicle, a maximum steering angle lock of approximately minus 80° up to approximately plus 80°, which is sensed by a steering angle sensor which generates a corresponding steering angle signal. In addition, a controller which is equipped with a data storage capacity and digital data processing capacity and which actuates the two motor controllers in such a way that when cornering occurs the two drive wheels (100 and 100') are each operated with a different torque is mounted on the vehicle (2). For example, the controller can bring about a starting and obstacle-overcoming mode which is executed at a vehicle speed of 0 to 2 km/h, wherein, at a large steering angle lock of up to 80°, the motor which is mounted on the wheel on the outside of the bend supplies approximately 90% of the total torque which is requested with the given acceleration rotational engagement position and the motor which is mounted on the wheel on the inside of the bend supplies approximately 10% of the total requested torque, that is to say a torque ratio of 90 to 10 is set. When there is a smaller steering lock, a proportionally correspondingly reduced torque ratio is set until such a torque ratio of 50 to 50 is reached for straight ahead travel.

L’invention concerne un véhicule électrique à trois roues conforme à la catégorie de véhicules CE L2e-U, lequel comprend deux roues arrières (100 et 100’) entraînées par moteur électrique, lesquelles sont respectivement entraînées par un moteur de moyeu de roue réalisé comme moteur synchrone polyphasé comprenant une commande de moteur intégrée, lequel est conçu pour une puissance nominale continue supérieure à 2 kW et inférieure à 6 kW, en particulier conçu pour une puissance nominale continue maximale d’environ 4 kW. Une fourche à ressort télescopique (80) est montée à pivotement sur l’extrémité avant de la carrosserie de véhicule (3), laquelle peut exécuter un angle de braquage maximal d’environ moins 80° jusqu’à environ plus 80° par rapport à la direction longitudinale du véhicule, lequel est détecté par un capteur d’angle de braquage, lequel génère un signal d’angle de braquage correspondant. En outre, un contrôleur muni d’une capacité de stockage de données et d’une capacité de traitement de données numérique est monté sur le véhicule (2), lequel commande les deux commandes de moteur de telle façon que, lors d’un virage, les deux roues d’entraînement (100 et 100') fonctionnent chacune avec un couple différent. Le contrôleur peut, par exemple, initier un mode de démarrage et de passage d’obstacles, qui est exécuté à une vitesse de véhicule de 0 à 2 km/h, dans le cas d’un grand angle de braquage de jusqu’à 80° le moteur monté sur la roue située à l'extérieur du virage fournissant environ 90% du couple total requis par la position donnée de la poignée d'accélération, et le moteur monté sur la roue située à l'intérieur du virage fournissant environ 10% du couple total requis, c’est-à-dire qu’un rapport de couple de 90 à 10 est réglé. Pour un angle de braquage plus faible, un rapport de couple proportionnellement réduit est réglé, jusqu’à atteindre pour la conduite en ligne droite un tel rapport de couple de 50 à 50.
