A non-rail bound, electrically or hybrid-electrically driven vehicle has a current collector for feeding electric traction energy from an overhead line system. The current collector has a sliding strip that is brought into sliding contact with a contact wire of the overhead line system above a travel lane. The sliding strip arrangement is pivotable transversely to a direction of travel. The vehicle has a limiter to at least unilaterally limit the transverse pivoting range of the sliding strip arrangement substantially to the width of the vehicle. A driver assistance system assists a driver in adhering to a virtual track within the marked lane. The track width and the pivoting range are dimensioned such that, when the track is adhered to, it is possible to maintain sliding contact between the sliding strip arrangement and the contact wire.

A pantograph includes a chassis, a bow, an articulated arm comprising at least one main rod and at least one auxiliary rod, an aileron assembly comprising at least one aileron which is movable relative to the articulated arm, support means for supporting the movable aileron which are movably mounted on the main rod or the auxiliary rod, means for immobilizing the support means relative to the support rod, and orienting means mounted on the main rod or the auxiliary rod. Over a first range of extension of the articulated arm, the orienting means do not act on the support means such that a characteristic angle of the aileron is substantially constant. Over a second range of extension of the articulated arm, the orienting means act on the support means such that the characteristic angle of the aileron varies continuously.

A system and a method for connecting a vehicle to an external source includes determining that a vehicle to be propelled by a drive system having one or more motors is to connect to an off-board power source while the one or more motors are powered by an onboard power source. The onboard power source is controlled to provide a determined amount of first electric energy to a first converter system. A second converter system is controlled to output an amount of second electric energy from the off-board power source within a designated threshold range. The second converter system is disposed between the off-board power source and the first converter system. The drive system receives power from the off-board power source responsive to the second converter system outputting the second amount of electric energy within the designated threshold range.

An energy transfer device is configured for electrically connecting an electrical vehicle to a charging station. The energy transfer device includes a lengthwise link having an upper end and lower end and a crosswise link having an upper end and lower end. The lower ends of the lengthwise link and the crosswise link are configured to be arranged on the electrical vehicle slidably in crosswise direction of the electrical vehicle. The upper end of the crosswise link is connected to the lengthwise link between its ends such that, by sliding the lower ends of the lengthwise link and the crosswise link towards each other, the upper end of the lengthwise link will be moved away from the electrical vehicle for connecting to the charging station.
