The present invention relates to a method for controlling an electrical power collector (70) configured to collect electrical power from a track line (30) of an electric road system arranged along a road (10). The track line (30) comprising activatable light indicators (40) arranged on the track line (30). The electrical power collector (70) being mounted on a vehicle (20). The method comprising, while the vehicle (20) is driving, capturing, using a camera (60) mounted on the vehicle (20), a video stream depicting the track line (30), identifying active light indicators in the captured video stream, and upon identification of active light indicators (40), activating the electrical power collector (70) such that a sliding contact (50) of the electrical power collector (70) makes sliding contact with the track line (30). Also a control circuit and a control system is presented.

A method and system include determining a resonant frequency of a vehicle system operably coupled with an external power source that provides voltage and current to the vehicle system. A first filter extracts a phase or a frequency component from the voltage provided by the external power source to generate a stabilizing voltage component. A second filter extracts a phase or a frequency component from the current provided by the external power source to generate a stabilizing current component. The stabilizing voltage component is out of phase with the stabilizing current component. A control input of a converter device of the vehicle system is determined based on the stabilizing voltage component, the stabilizing current component, and the resonant frequency. The stabilizing voltage component, the stabilizing current component, and the control input are communicated with the converter device to change the resonant frequency of the vehicle system.
