  • Publication number: 20170294900
    Abstract: The method for automated manufacturing of an electronic circuit tolerant to faults by temporal redundancy of maximum order N, comprising a step implemented by computer, according to which every memory cell of the circuit is replaced by a memory block (40) comprising a chain of memory cells in series, and a selection block which, in a temporal redundancy mode of order n1, n1?[1,N], selects as output data of the memory block the majority content of n1 cells of the block, and can furthermore deliver a fault signal if the contents of the n1 cells differ. Said method is characterized in that the inserted memory blocks allow a dynamic switching from a temporal redundancy mode of order n1 to any other mode of order n2. Said method for N=2, in association with a mechanism for recording with roll-back, allows an error with only a double redundancy instead of a triple redundancy.

    Abstract: The invention concerns a method of driving assistance for assisting a human driver in safely driving a vehicle called host vehicle, implemented by a processor on board of said host vehicle. The host vehicle comprises means for obtaining first information relative to the host vehicle and means for obtaining second information relative to at least one other vehicle in a neighborhood of the host vehicle, said first and second information being obtained at regular time instants, comprising triggering an intervention of a collision avoidance system. The method comprises a step (51) of intervention decision adapted to decide whether to trigger the intervention of the collision avoidance system at a current time instant (Tc) or to postpone said intervention decision at a later time instant (Tl) depending upon additional first and second information to be acquired between the current time instant (Tc) and the later time instant (Tl), said additional first and second information having an associated probability.
