Problems solved by technology

[0007] However, such abutment during steering tends to generate collisions within the steering device and thus cause the appearance of noise, or even wear of the mechanical parts of the steering device

Embodiment Construction

[0032] The invention relates to a method of managing a power steering motor 1 during which an assistance set point Ctot intended to be applied to a power steering motor 1 designed to provide an assistance force (Assistanceforce) is stated , to operate the actuator part 2 of the steering rack type steering device 5, said actuator part 2 being at least movably mounted between a first position P1 and a second position P2, which are far away from each other and limit the The functional stroke L0 of the actuator part 2 thus allows said actuator part to modify the direction angle of the steering wheel type steering device parts 3, 4.

[0033] Such as figure 2 As shown in , said steering device 5 preferably comprises a steering wheel 6 intended to control the displacement of said actuator member 2 , preferably by means of a steering column 7 .

[0034] Preferably, said actuator member 2 is formed by a steering rack slidably mounted in a steering housing, not shown, which is fixed t...

Abstract

The invention relates to a method for managing a power-steering motor designed to supply a force to assist the movement of a steering rack, said steering rack being mounted such as to be movable between at least a first position (P1) and a second position (P2) in order to be able to change the steering angle of a steered wheel. Said method comprises: defining a virtual end-of-travel threshold (S1, S2) strictly comprised between the first position (P1) and the second position (P2); and if the rack is detected as having crossed said virtual end-of-travel threshold (S1, S2) in a predetermined crossing direction (F1, F2), simulating, by means of the power-steering motor, an end-of-travel stop by including in the assistance instruction a resistance instruction that simulates the effect of a mechanical stop, such as a spring-damper or a mass-spring-damper, preventing the actuator member from progressing beyond the virtual end-of-travel threshold (S1, S2).

Description

technical field [0001] The present invention relates to the general field of power steering devices for vehicles, and in particular for motor vehicles. Background technique [0002] Usually, such a power steering device comprises an actuating member of the steering rack type movably mounted in translation in a steering housing fastened to the chassis of the vehicle, the displacement of which is controlled by the steering Column control, the steering column is driven by the steering wheel and supports a pinion that meshes with the steering rack. [0003] Each end of said actuating member is generally connected by means of a tie rod to a steering device member usually formed by a steered wheel carried by a stub shaft which can be orientated about its yaw axis. [0004] In order to assist the manual force exerted by the driver on the steering wheel when manipulating the actuating member, the power steering motor (which generally meshes with the steering column or the steering ...
