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.
