The ultrasonic tracking control effects that a pacemaker going ahead is automatically tracked by an automotive vehicle at a pre- determined distance. To this end, a control unit (13) of the vehi- cle (10) is equipped with two ultrasonic units (F1,F2) comprising a transceiver device for ultrasonic signals each. The pacemaker going ahead carries a second control unit (14) with a transponder (S) responding to the signals of the ultrasonic units (F1,F2). Upon reception of an ultrasonic signal, the transponder (S) out- puts a response signal which is received by the respective ultra- sonic unit. The distance of the vehicle from the pacemaker and the tracking angle (.alpha.) are determined in the first control unit (13) from the signals received by the ultrasonic units (F1,F2), and traveling and steering signals are generated such that the vehicle tracks the pacemaker at a predetermined distance.
