    摘要： The present invention relates to a method for orienting a power receiving coil of a vehicle relative to a power emitting coil of a wireless charging system for a vehicle. The method comprises:
    - detecting a positioning of the vehicle at a charging location in which the power receiving coil detects reception of electromagnetic radiation emitted from the power emitting coil,
    - performing a calibration sequence in which the orientation of the power receiving coil and/or the power emitting coil is varied according to a predetermined scheme, while registering the electromagnetic radiation reception of the power receiving coil,
    - in response to the calibrations sequence, determining a desired relative orientation including relative angle between the power receiving coil and the power emitting coil for which the electromagnetic radiation reception of the power receiving coil is in a top range of the registered electromagnetic radiation reception.

    摘要： The invention relates to a vehicle system (100) for a subject vehicle (1) driving in a vehicle formation (VF) with at least one lead vehicle (200), comprising:
    - an energy system (10) configured to transfer energy between the subject vehicle (1) and another vehicle (200) during driving in the vehicle formation (VF);
    wherein the vehicle system (100) further comprises:
    - an information obtaining system (20) configured to obtain information indicative of a driving situation in front of the lead vehicle (200) during driving in the vehicle formation (VF); and
    wherein the vehicle system (100) is configured to:
    - terminate transfer of energy or inhibit initiation of transfer of energy if the information obtaining system (20) obtains information indicative of a hazardous driving situation in front of the lead vehicle (200). The invention also relates to a method, at least one control, a subject vehicle and a vehicle formation.

    摘要： The invention relates to a monitoring circuit (305) for monitoring of a PE (113) connection in a vehicle charging interface (300) of a vehicle (200). The vehicle (200) is at least partly electrically powered. The monitoring circuit (305) is connected to a first line (308) of a communication circuit (303). The monitoring circuit (305) and the communication circuit (303) are separate circuits. The monitoring circuit (305) comprises a current source (313), a current measuring unit (315) and the PE connection (113). The current source (313) is adapted to generate a current running through the monitoring circuit (305). The current measuring unit (315) is adapted to measure the current running through the monitoring circuit (305) and thereby monitoring the PE connection (113).
