Abstract:
The present invention refers to a system for the control of the machine torque of a vehicle (1) comprising a first drive wheel (2') associated to a first motor (3') and a second drive wheel (2") associated to a second motor (3"). The control system comprises a user-interface device (13) for the control of the system by the user and a drive module (11) comprising: a module (15) for determining a common reference drive signal (lcommon) representing a reference torque which is common to the first (3') and the second (3") motor on the basis of at least a signal representing the throttle level of the accelerator member; a module (21) for determining a reference yaw rate on the basis of at least signals representing the steering angle and the speed of the vehicle (v) according to a predetermined relation which can be defined by the user through the user-interface device (13); a module (18) for determining of a differential reference drive signal (ΔΙ) representing a reference torque difference between the first (3') and the second (3") motor on the basis of at least a signal representing the yaw rate of the vehicle and the reference yaw rate.
