Summary:A method for determining the speed of a rail-bound vehicle, includes the following method steps: detection of a reference element, wherein the first detection device generates a first detection signal when the reference element passes the first detection device; detection of the reference element, wherein the second detection device generates a second detection signal when the reference element passes the second detection device; conversion of the detection signals into digital detection pulses; determining the time difference between the two detection pulses; wherein an XOR signal is generated in an XOR gate by linking the first and the second detection pulse using an XOR logic; and the duration of the XOR signal is determined; and wherein the time difference between the two detection pulses is determined by halving the duration of the XOR signal. The speed can be measured with higher accuracy when using an existing infrastructure without additional assembly work.
