Abstract
A method for controlling a power steering system of a vehicle which is intended to limit the physical supply current supplied to the at least one power steering motor in the event of an impact between at least one rack and at least one mechanical end stop, the control method including: —a determination step wherein the power steering computer determines a setpoint torque for the power steering motor; —a driving step wherein the power steering computer determines the setpoint supply current for the power steering motor; wherein the control method also includes: —a detection step wherein the power steering computer detects an impact between rack and mechanical end stop; —a protection step emitting a protected signal to the driving step when an impact is detected, so that the setpoint supply current determined by the driving step is below a maximum setpoint supply current.
