The invention concerns a method for managing a power steering system comprising at least one steering wheel (3) and at least one assist motor (4), said method comprising a step of (b) driver torque control, which involves evaluating a driver torque difference (ΔCcond) that corresponds to the difference between a predefined driver torque setpoint (Ccond_réf) and the actual driver torque (Ccond) actually exerted by the driver on the steering wheel (3), then determining an engine torque setpoint (Cmot_réf) for torque applied to the assist motor in order to reduce said driver torque difference, the driver torque setpoint (Ccond_réf) being generated during a trajectory control step (a), which involves evaluating a trajectory difference, for example a position difference (Δθ), which corresponds to the difference between a trajectory setpoint, of the position setpoint (θréf) type, which depends on a reference trajectory, and the actual trajectory (θ) of the vehicle, given by the measured position of the power steering, then determining, from said trajectory difference (Δθ), a driver torque setpoint (Ccond_réf) intended to reduce said trajectory difference. |
