| 摘要 |
The invention concerns a control method for a power-assisted steering module, said method comprising a step (a) of assessing the steering wheel torque which involves obtaining an indicator signal representative of the intensity of the steering wheel torque (Cvolant) exerted by the driver on the steering wheel, a monitoring step (b) which involves comparing the indicator signal, representative of the intensity of the steering wheel torque (Cvolant), to a pre-defined alert threshold (C1), then, if said indicator signal becomes higher than or equal to said alert threshold (C1), a step (c) of reducing the assistance which involves reducing the intensity of the assistance torque (Cassist) provided by the assistance motor (12), such that the sum of the steering wheel torque (Cvolant) and the assistance torque (Cassist) remains lower than or equal to a pre-defined critical operating torque, in order to preserve the steering tie-rods from plastic deformation. |
