Abstract (en)

[origin: EP0913309A2] The method involves generating an auxiliary signal from a detection device with each lead unit entering the track section (1). The control signal (St)is formed using the respective auxiliary signal. The detection device is a speed measurement device (9) which outputs the auxiliary signal as a speed measurement value representing the entry speed of each lead unit. The speed measurement value or an auxiliary value (Vm) formed from the speed measurement is compared with a threshold value and a first intermediate signal (S1) generated, if the threshold is exceeded. A distance measurement device (12) measures the distance to the distance measurement device at which the next lead unit enters the section. A second intermediate signal (S2) is generated when the distance measurement value (L) falls below a second threshold value. A control signal is generated when the first and the second intermediate signals (S1,S2) were generated.
