1. A system (1) for controlling the jerk for an automatic/autonomous vehicle, said system comprising:
sensor means (4) configured to measure the acceleration of said vehicle and provide an electric signal (IA) indicating said acceleration,
a driving control module (3) of said vehicle configured to provide an electric braking signal (IF, SEM) and
a braking system (2) configured to brake said vehicle as a function of an electric input signal (SS, SR, SEM),
said system (1) comprising processing means (5) which comprise a jerk calculation module (6) configured to acquire said electric signal (IA) and calculate a jerk value (IJ) of said vehicle and a plurality of operating modules (7), each configured to acquire said electric braking signal (IF, SEM) and said jerk value (IJ),
one of said plurality of operating modules (7) being selected by means of a selection signal (US, UR), said selected module modifying the electric braking signal (IF, SEM) as a function of said jerk value (IJ) and providing a modified electric braking signal (SS, SR) to said braking system (2), the plurality of operating modules including a first and a second operating module (7), said first operating module sending a modified breaking signal (SS) to generate a jerk value (IJ) that meets with first and second safety conditions, the second module sending a modified braking signal (SR) to said braking system to generate a jerk value (IJ) that meets only the second safety condition and is greater than the jerk value generated by the modified braking signal (SS) send by the first operating module.
