A method of assisting a driver of a vehicle includes identifying a road to be driven by the driver using a position determination unit. A parameter is selected to assist a driver of the vehicle in driving a segment of the road. The parameter includes information on the location of a boundary along the road and a preferred trajectory to be driven along the road. A controller determines whether a driven trajectory of the vehicle while travelling the road is deviating from the preferred trajectory of the vehicle along the road. A feedback operation is provided while travelling the road to assist the driver in guiding the vehicle from the driven trajectory nearer to the preferred trajectory based on the selected parameter. The preferred trajectory is updated based on the driven trajectory of the vehicle along the road.
