  • Patent number: 8521346
    Abstract: A method for operating a rail vehicle includes coasting point determination for a route section. Upon reaching that point, vehicle traction is deactivated and coasting occurs over at least part of the remaining route to a route section end. Coasting points are stored for the route section and assigned a fixed distance and fixed travel time to the section end. Upon passing the route section, continuous evaluation is performed whether a currently recorded distance to the section end is shorter than the fixed distance to the route section end for one coasting point according to a first condition, and whether a current travel time to the section end is longer than or equal to the fixed travel time to the section end according to a second condition. Possible traction deactivation is signaled when fulfilling both conditions. If not fulfilled, another stored coasting point is evaluated for fulfillment of the conditions.

  • Patent number: 8515662
    Abstract: A method and arrangement are configured for determination of the energy consumption of a transportation device per section of the route, in urban traffic, for example. In an embodiment, current energy consumption data is compared to reference data from a fleet of transportation devices. The result is visually conveyed to the driver to allow them an interpretation of the energy consumption and to provide motivation for energy-saving driving behavior. An evaluation of the energy consumption data relative to the route allows specific feedback, for example, that the driver has achieved an energy-saving best value for a section of the route. The gathered data can also be used to pay bonuses or to initiate training measures.
