Abstract (en)
[origin: FR2899282A1] The system has a preventive authorization unit (38) with a calculation module (44) connected to a resistive torque calculation module (42). The module (44) calculates a resistive torque value that is returned to a drive train (12) and corresponds to a passage torque of a transmission backlash. The unit (38) has a torque threshold calculation module (46) connected to the modules (42, 44). The module (46) calculates and delivers the torque threshold value to the drive train according to a numerical relation, for controlling the drive train.
