A method supports a vehicle's traffic-light-sequence assistant system that detects traffic light sequences of a traffic light (11) with a camera (1). According to the method, when the traffic light (11) is detected in the field of view (1a ) of the camera (1), a length or an end stopping point (L) of a driving path (W) toward the traffic light (11) is determined by a control unit (3), such that the traffic light will remain within view of the camera when the vehicle drives the determined length along the driving path to the end stopping point, and a control signal (St) concerning the determined length (L) or the end stopping point of the driving path (W) is outputted.
