Abstract
Description
Die vorliegende Erfindung bezieht sich auf ein elektrisches Kraftlenksystem für einen kraftunterstützenden Lenkbetrieb eines Lenkrads.The The present invention relates to an electric power steering system for a power assisted steering operation of a Steering wheel.
Wie
in der
Gemäß dem herkömmlichen elektrischen Kraftlenksystem kann das Lenkrad nicht kraftunterstützt werden, sobald bei einer der Leistungsschaltvorrichtungen der Kurzschlussfehler auftritt.According to the conventional electric power steering system can be the steering wheel not power assisted once on one of the power switching devices the short circuit fault occurs.
Es ist daher eine Aufgabe der vorliegenden Erfindung, ein elektrisches Kraftlenksystem zu schaffen, das ein Lenkrad weiterhin kraftunterstützen kann, selbst wenn bei einer von mehreren Leistungsschaltvorrichtungen ein Kurzschlussfehler auftritt.It is therefore an object of the present invention, an electrical To provide a power steering system that can continue to power a steering wheel, even if one of several power switching devices a short circuit fault occurs.
Gemäß einem Aspekt weist ein elektrisches Kraftlenksystem einen bürstenlosen Motor mit drei oder mehr Phasen, der ein Drehmoment zum Unterstützen eines Lenk rads erzeugt, eine Leistungsumwandlungseinheit mit einer Mehrzahl von Leistungsschaltvorrichtungen, die in eine Brückenform geschaltet sind, die eine Gleichstromleistung in eine Wechselstromleistung mit mehreren Phasen, die dem bürstenlosen Motor entsprechen, umwandelt, um dem bürstenlosen Motor die Wechselstromleistung zuzuführen, und eine Steuerungseinheit zum Steuern der Leistungsumwandlungseinheit auf. Wenn eine der Leistungsschaltvorrichtungen kurzgeschlossen wird, trennt die Steuerungseinheit eine einen Kurzschlussfehler aufweisende Leistungsschaltvorrichtung von dem bürstenlosen Motor und fährt fort, die Leistungsumwandlungseinheit zum Zuführen der Wechselstromleistung zu dem bürstenlosen Motor zu steuern.According to one Aspect, an electric power steering system has a brushless Motor with three or more phases providing torque to assist a steering wheel generates, a power conversion unit with a Plurality of power switching devices in a bridge shape are switched, which convert a DC power into an AC power with several phases that correspond to the brushless motor, converts to the brushless motor the AC power supply, and a control unit for controlling the Power conversion unit. If one of the power switching devices is shorted, the control unit disconnects a short circuit fault having power switching device of the brushless Engine and continues the power conversion unit to Supplying the AC power to the brushless To control engine.
