METHOD FOR ESTIMATING A VALUE OF A FRICTION FORCE EXERTED ON A PART OF A POWER STEERING SYSTEM BY MEANS OF A MATHEMATICAL MODEL

摘要

The invention relates to a method for estimating a value of a friction force exerted on a part of a power steering system (1) of a vehicle (2), said part of the power steering system (1) comprising at least one motor (12) exerting a motor torque (T12), said value of the friction force making it possible to modify the motor torque (T12), by means of a mathematical model.
