A motor vehicle has a control device, a first sensor and a global positioning device. The control device has a control unit and a data memory. At least one item of information about an arrangement of an overhead line is stored on the data memory. The control unit is connected to the first sensor and to the global positioning device. The first sensor determines a position of the overhead line relative to the motor vehicle and provides the control unit with the relative position. The global positioning device determines a global position of the motor vehicle and provides the control unit with it. The control unit, on the basis of the established relative position, the established global position and the information about the arrangement of the overhead line, calculates a position of the motor vehicle.

A system includes a support, a sensor coupled to the support and arranged to output signals in a direction towards a haul road on which a machine traverses, an indicator coupled to the support, a first line coupled to the support, and a second line coupled to the support. Sensor data is received from the sensor, and based on the sensor data, a position of the machine on the haul road is determined. An alignment of the machine on the haul road is determined, where the alignment is associated with the machine maintaining contact with the first line and the second line. An indication is displayed for laterally aligning the machine on the haul road.

A monitor device is provided with an imaging device that shoots an overhead line and a current collector, and a controller that processes an image. The controller includes a day or night determination processing section, and an image processing section that switches a parameter for recognizing the overhead line and the current collector in the image by executing image processing different in the daylight and at night based upon the result of the day or night determination. Further, there are provided reference photographic subjects to be shot by the imaging device in positions different from the overhead line and the current collector in an image area to be shot, and the day or night determination processing section performs the determination of day or night based upon a luminance average value of the reference photographic subjects inputted into an image input section.

A vehicle control facility for the automated control of an electrical road vehicle for a route system with an energy-supply system that includes a lane-bound energy supply line, in particular an overhead line system. A position-determining unit determines a geographical position of the electrical road vehicle. A specific-lane-determining unit determines position data for a specific lane assigned to the lane-bound energy supply line. A communication interface transmits current relative positions of infrastructure features with respect to the electrical road vehicle to an external central specific-lane-determining facility and receives position data. A vehicle-control unit controls the electrical road vehicle with respect to the determined specific lane in dependence on the determined relative position of the specific lane.

A current collector for an electrical load that can be moved along a conductor line in a travel direction. The current collector has at least one contact piece, which is supported on a rocking arm to be rotatable about an axis of rotation extending perpendicularly to the travel direction. To bring the contact piece into contact with an electrically conductive conductor strand of the conductor line, the contact piece can be moved toward the conductor strand by the rocking arm. The current collector also includes a connection cable, which connects the contact piece to a connection terminal for the electrical loads in an electrically conductive manner. A conductor line system includes a conductor line and at least one electrical load that can be moved on the conductor line in the longitudinal direction of the conductor line. The conductor line has at least one electrically conductive conductor strand for bringing into sliding contact with at least one contact piece of a current collector.

Methods and systems for an ice cap to prevent ice buildup on electrical cables or wires such as grooved cables that carry electricity to transportation vehicles are disclosed. The ice caps can be attached to grooved cables or wires and partially envelop them. The ice cap includes an inverted V-shaped structure and a pair of members descending from its apex and configured to form a canopy over the cable while allowing free access to the bottom portion of the cable by a current collector. It provides a cover over the cable allowing run off of rain, snow and sleet. Grooves present on the edges of the descending members disrupt ice buildup on the cable and increase the ice prevention efficiency of the ice cap. Descending members of the ice caps could also extend over neighboring cables to which they do not attach directly to prevent ice formation on them.
