System adapted for one or more electrically propellable vehicles (detector arrangement)

A vehicle-related detector arrangement related to a contact means in a system for propelling an electrically propellable vehicle, by one or several batteries or a set of batteries along a roadway, the system comprising:

• a plurality of roadway sections for subdividing the roadway, wherein each one of the roadway sections comprises one or more elongated tracks or slits having conducting rails introduced therein adapted to be supplied with current and put under voltage, and being connectable over a switch to one or more vehicle-external power sources, including electric stations, for thereby enabling charging said set of batteries belonging to the vehicle but primarily driving the vehicle over the set of batteries along the roadway and the roadway sections and
• one or more powerable vehicles which may be driven by means of an electric motor or motors, with each of the respective vehicles comprising a control circuit adapted for necessary distribution of power, and for providing a required power and/or speed control, wherein an underneath side of said vehicle is provided with contact means displaceable up and down and sideways, in relation to the direction of transportation of the vehicle,
• wherein said elongated track or tracks and the conducting rails extend along the stretch of the roadway and wherein said contact means is coordinated with vehicle-related control equipment for creating an adaptation of the contact means so as to at least offer a mechanical and electrical contact with said conducting rails,
• wherein coordination between the conducting rails, arranged in the roadway section and the contact means of the vehicle occurs via coordinated current collectors, in the form of contact springs adapted for mechanical and electrical cooperation with respective ones of the conducting rails put under voltage,
• wherein the system comprises one or more electric conductors disposed collaterally with said track in the roadway, through which a current is adapted to pass, and/or one or a plurality of permanent magnets, for generating a magnetic field,
• wherein the detector arrangement comprises a coil, related to the vehicle, and adapted to sense the variation of said magnetic field based on a distance from a track and/or a height of the coil above said track and to actuate, the contact means, over the control equipment by means of associated auxiliary motors, for cooperation with the track and the conductor.
