Abstract: A computer for a motor vehicle including at least one main control module intended to manage an onboard system such as a power steering system, which uses a plurality of internal variables representative of the successive life situations of the vehicle, the computer including, in addition to the main control module, an integrated monitoring module that includes an extraction and recording unit, placed under the dependency of a trigger unit in order to extract, from a buffer memory, in case of a detection of a predefined alarm event occurring at a triggering time, one or more recordings, that correspond respectively to one or more internal variables, and that each cover a time interval that extends from a start time that precedes the triggering time to an end time that follows the triggering time, and then to store the recording or recordings in a non-volatile memory.

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.
