1. A method of assisting a driver of a vehicle, the method comprising the steps of: identifying a road to be driven by the driver using a position determination unit; selecting a parameter to assist a driver of the vehicle in driving a segment of the road, the parameter including information on a location of a boundary along the road and a location of a preferred trajectory to be driven along the road with respect to the boundary and indicates when to apply a feedback force, the parameter further including a feedback force gradient for determining the amount of the feedback force to be applied, the feedback force being calculated according to the feedback force gradient; determining, via a controller in communication with a sensor system, whether a current trajectory of the vehicle while travelling the road is deviating from the preferred trajectory of the vehicle along the road; and providing a feedback operation to assist the driver in guiding the vehicle nearer to the preferred trajectory based on the selected parameter, the feedback operation including the application of the feedback force.
