Electric power-assisted steering motor thermal protection managing method for motor vehicle, involves applying progressive reduction of electrical assistance when calculated assistance current value reaches threshold value
The method involves calculating a maximum current value authorized to traverse an electrical power steering motor, and determining a threshold value of the calculated maximum current. A progressive reduction of electrical assistance is applied when the assistance current value calculated at every moment according to a torque that is applied to a control wheel reaches the threshold value.
