Method and system for controlling a vehicle in presence of hydroplaning

Abstract

Control method and system () of a vehicle () moving on a road surface, wherein the system comprises a detection module () for detecting in real time a respective hydroplaning intensity (HI) for each tyre () of the vehicle (), an actuation device () connected to each wheel () of the vehicle () and a command and control unit () programmed and configured for performing the control method comprising: —comparing each respective hydroplaning intensity (HI) with a first threshold; —upon the occurrence of a starting condition such that the respective hydroplaning intensity (HI) of at least one tyre () reaches the first threshold, then: —calculating in real time a reference value (YRr) of a parameter representative of a lateral motion of the vehicle () as a function of a longitudinal speed (Vxc) and of a steering angle (STA) of the vehicle; —calculating in real time a corrective moment (Mz) as a function of the reference value (YRr) and of a current value (YRc) of the parameter detected in real time; —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 ().
