| 摘要 |
The present invention relates to a method for determining a link force (Fbiellette) within a power-steering mechanism (1) of a vehicle, said method comprising a step (a) of determining an actuation force, which involves determining the actuation force (Faction) that results from the assistance force (Fassist) exerted by the assistance motor (2) and the driver force (Fcond) exerted by the driver of the vehicle on said steering mechanism; a step (b) of assessing dry friction (Fdry, Rdry); and a step (c) of calculating the link force (Fbiellette), which comprises a summation sub-step (c1) which involves calculating an expression (22) representing the link force, which uses the algebraic sum of the actuation force (Faction) and the dry friction force (Fdry), and a filtering sub-step (c2) which involves applying a low-pass filter (23) in order to smooth the result of said expression (22) when said expression is calculated upon a steering reversal (15) of the steering mechanism. |
