Method and system for controlling a vehicle in presence of hydroplaning

A control system of a vehicle moving on a road surface, wherein the system comprising:

• a detection module for detecting in real time a respective hydroplaning intensity (HI) for each tyre of the vehicle rolling on the road surface;
• an actuation device operatively connected to each wheel of the vehicle;
• and
• a command and control unit operatively connected to the detection module and to the actuation device, and programmed and configured for:
• comparing each respective hydroplaning intensity (HI) with a first threshold;
• when an occurrence of a starting condition of the respective hydroplaning intensity (HI) of at least one tyre reaches the first threshold, then:
• receiving as input in real time a first signal representative of a current value of a longitudinal speed (Vxc) of the vehicle;
• receiving as input in real time a second signal representative of a steering angle (STA) of the vehicle;
• calculating in real time a reference value (YRr) of a parameter representative of a lateral motion of the vehicle as a function of the first and second signal;
• receiving as input in real time a third signal representative of a current value (YRc) of the parameter;
• calculating in real time a corrective moment (Mz) as a function of the reference value (YRr) and of the current value (YRc) of the parameter;
• and
• commanding the actuation device for applying in real time to each wheel a respective torque (Tr) calculated in real time as a function of the corrective moment (Mz) and of the hydroplaning intensity (HI) of the respective tyre.
