Abstract
A method for managing a power-steering motor configured to supply a force to assist the movement of a steering rack involves the steering rack being mounted such as to be movable between at least a first position and a second position in order to be able to change the steering angle of a steered wheel. The method includes the steps of defining a virtual end-of-travel threshold strictly between the first position and the second position. If the rack is detected as having crossed the virtual end-of-travel threshold in a predetermined crossing direction, simulating, by 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 further beyond the virtual end-of-travel threshold.
