| 摘要 |
The present invention relates to a method for estimating the ageing of a steering mechanism (1) during which the ageing of the steering mechanism is assessed by calculating a so-called ageing value in accordance with an ageing function (old, old2, ene) which corresponds to the integral, over time, of an expression which is weighted by a stress indicator (Tm(u), Ts(u)), the value of which, at each moment (u) in question, is representative of the strength of a biasing force (Tm, Ts), such as the control force exerted by the power-steering motor (2), that is applied to said steering mechanism (1) at said moment in question. |
