Patent attributes
An opening system for a vehicle includes a frame having an opening, an opening member that is movable relative to the frame between a closed position and an open position, and a retaining device. The retaining device includes a ferromagnetic element provided on the opening member, a magnet provided on the frame and magnetically coupled to the ferromagnetic element when the opening member is in the closed position, an electromagnet coupled to the magnet, and a control unit having a control module that controls the electromagnet upon reception of a control command. The control unit includes a detection module which, in the absence of a control command being received by the control module, is enabled for the detection of a signal, originating from the electromagnet, representative of the opening member reaching the closed position.
