An apparatus generates position signals to indicate the position of a rail-bound vehicle along a travel way throughout which travel way many markings are located. The apparatus includes at least one sensor located on the vehicle for scanning the markings and outputting signals and an evaluation unit
An apparatus generates position signals to indicate the position of a rail-bound vehicle along a travel way throughout which travel way many markings are located. The apparatus includes at least one sensor located on the vehicle for scanning the markings and outputting signals and an evaluation unit that is connected to the sensor for generating the position signals by evaluating the signals generated by the sensor by scanning the markings. When the vehicle passes a marking, the sensor outputs a “marking present” signal and otherwise outputs a “marking absent” signal. The vehicle has a receiver of a navigation system that is connected to the evaluation unit and outputs current location signals. The evaluation unit is connected to a memory device (20) for storing position data associated with the markings, where, upon receiving each “marking present” signal, the evaluation unit outputs a position signal associated with the marking based on a comparison of the current location signal and the memory-stored position data.

1. An apparatus located on a rail-bound vehicle (7) generates position signals, which indicate the position of the rail-bound vehicle (7) along a travel way (1), including many markings (9, 23), located along the travel way (1), at least one sensor (11), for scanning the markings (9, 23) and outputt
1. An apparatus located on a rail-bound vehicle (7) generates position signals, which indicate the position of the rail-bound vehicle (7) along a travel way (1), including many markings (9, 23), located along the travel way (1), at least one sensor (11), for scanning the markings (9, 23) and outputting signals thus ascertained, and an evaluation unit (17), connected to the at least one sensor (11), for generating the position signals by evaluating the signals generated by the markings (9, 23); wherein the markings (9, 23) are embodied such that when the rail-bound vehicle (7) passes a marking (9, 23), the sensor (11) outputs a “marking present” signal and otherwise outputs a “marking absent” signal; wherein the rail-bound vehicle (7) has a receiver (18) of a navigation system configured, for outputting current location signals and which is connected to the evaluation unit (17); wherein the evaluation unit (17) is connected to a memory device (20), in which position data associated with the markings (9, 23) are pre-stored; and wherein the evaluation unit (17), upon receiving each “marking present” signal, outputs a position signal associated with the marking (9, 23) on the basis of a comparison of the current location signal with the pre-stored position data. 2. The apparatus as defined by claim 1, characterized in that the sensor (11) includes a transmitter (12) that transmits a beam of light (16) and a receiver (14) for the beam of light (16), and the markings (9) are embodied as mirrors, which when the vehicle (7) passes them deflect the beam of light (16), generated by the transmitter (12), to the receiver (14). 3. The apparatus as defined by claim 2, characterized in that the light source includes a laser. 4. The apparatus as defined by claim 1, characterized in that the sensor (11) includes a transmitter (12) transmitting a beam of light (16), a receiver (14) for the beam of light (16), and a mirror (22) that deflects the beam of light (16), generated by the transmitter (12), to the receiver (14); and that the markings (23) are embodied as components that interrupt the beam of light (16). 5. The apparatus as defined by claim 1, characterized in that the evaluation unit (17) is connected to a radio system (21) mounted on the vehicle (7). 6. A system for automatically tracking a rail location of a rail-bound vehicle, comprising: apparatus located on the rail-bound vehicle generates position signals that indicate a position or rail location of the rail-bound vehicle along a travel way throughout which multiple position markings are arranged, the apparatus including: at least one sensor configured for scanning the position markings and outputting signals as the rail-bound vehicle moves past the position markings arranged along the travel way; andan evaluation unit connected to the sensor and a memory device with pre-stored position data associated with the position markings, the evaluation unit generating the position signals by evaluating the signals output by the at least one sensor when scanning the position markings in view of the pre-stored position data; anda receiver of a navigation system, which is connected to the evaluation unit, for outputting current location signals;wherein, when the vehicle passes a position marking, the at least one sensor outputs a “marking present” signal and otherwise outputs a “marking absent” signal and wherein the evaluation unit, upon receiving each “marking present” signal, outputs a position signal associated with the position marking based on a comparison of a current location signal generated by the navigation system receiver and the position data pre-stored in the memory device.
