separate device and stops the truck distinctly from the Elaboration Unit. This is
exactly what the Passive Emergency Cell does.
In a system with a single microprocessor technology, the weak point is that just
one unit (uC) processes the Inputs and decides alone to keep the motor moving
or not. If this elaboration unit (uC) fails it is possible it keeps the motor moving
against of the state of the commands. To avoid this risk, the Passive Emergency
cell provides a further step of safety that is a redundancy in processing the
motion request (Tiller or Seat Switch). In our controller the truck will be stopped,
releasing the tiller, disregarding if the main Elaboration Unit (uC) is right working
or not.
