Abstract
A method is provided for intelligent scaling of torque overlay intervention for a semi-autonomous steering system in a road vehicle having a semi-autonomous steering function arranged to selectively apply a steering wheel overlay torque. If decided that a driver is significantly overriding an intervention, the overlay torque is scaled by a scaling factor being a function of applied steering wheel torque. If decided that the driver has been significantly overriding the intervention for more than a pre-determined first time period, the scaling factor is set to its lowest possible value for a specific driving situation. If decided that the driver has been significantly overriding the intervention for more than a pre-determined second time period, where the pre-determined second time period is equal to or exceeds the pre-determined first time period, the scaling factor is faded-out.
