ANTI-ROLLOVER DEVICE FOR VEHICLES

摘要

An anti-rollover device for a vehicle includes at least two safety legs, each arranged at respective sides of the vehicle, and having a free end portion and an opposite end portion constrained to the vehicle, through which the safety legs are connected to the vehicle movably between a rest position and a support safety position in order to stop a lateral rollover of the vehicle. The device also includes an actuator for moving each leg from the rest position to the support safety position; a sensor for measuring a quantity related to an early rollover condition of the vehicle, the sensor configured for producing a measurement signal; an automatic controller for receiving the measurement signal and for sending the control signal to the actuator, so that in case of a rollover condition at least one of the legs moves from the rest position to the support safety position.

主权项

1. An anti-rollover device (1,50,70,80,90) for a vehicle (10) having lateral sides (10′,10″), a longitudinal axis (15) and a longitudinal midplane (16), said anti-rollover device (1,50,70,80,90) comprising:
at least two safety legs (5,31′,31″,51′,51″) comprising a right safety leg (5, 31′, 51′) and a left safety leg (5, 31″, 51″), each arranged at a respective side (10′, 10″) of said vehicle (10), each of said safety legs (5, 31′, 31″, 51′,51″) having a free end portion (3,59) and an articulated end portion (4,54′,54″,87′,87″) opposite to said free end portion (3,59), wherein each of said safety legs (5,31′,31″ 51′,51″) is connected to said vehicle (10) through said articulated end portion (4,54′,54″,87′,87″), wherein each of said safety legs (5,31′,31″,51′,51″) is movable between a rest position (R), with minimum encumbrance with respect to said vehicle, and a support safety position (S), in which said free end portion (3,59) is located at a safety distance (D) from a respective side of said vehicle (10) so as to stop the rollover of said vehicle by one of said safety legs (5,31′,31″,51′,51″), an actuator (100;55,56,60,67) configured for causing each of said safety legs (5,31′,31″,51′,51″) to move from said rest position to said support safety position; a sensor (110;91,92,94) for detecting a value of a quantity related to an early rollover condition of said vehicle (10), said sensor configured for producing a signal (110′;91′,92′,94′) responsive to said value; an automatic control unit (120) configured for receiving said signal (110′) and for activating said actuator (100,55,56,60,67) according to said signal (110′), in such a way that, in said early rollover condition, said actuator (100) causes at least one of said safety legs (5,31′,31″,51′,51″) to move impulsively from said rest position (R) to said support safety position (S),wherein said automatic control unit (120) comprises a logical unit (125) for carrying out a comparison of said signal (110′;91′,92′,94′) with a limit value of said quantity, beyond which an early rollover condition of said vehicle occurs, said automatic control unit (120) configured for triggering said actuator (100;55,56,67) when said logical unit (125) assesses said early rollover condition by said comparison.
