A sensor is provided on the vehicle of a driverless transport system. The sensor is based on the principle of a computer mouse for ascertaining either a drift angle DELTAalpha or the transverse movement is detected as a path difference DELTAq whereby lateral drift due, for example, to roadway covering irregularities and to curves, is detected directly. A considerable improvement in the tracking accuracy of driverless transport vehicles is thereby provided.
