US Patent 10457327 Method and system of assisting a driver of a vehicle

A method of assisting a driver of a vehicle includes obtaining a feature of a road to be traveled by the vehicle with a sensor and/or a GPS system. A parameter is selected to assist a driver of the vehicle in driving a segment of the road based on the feature 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 current 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 to assist the driver in guiding the vehicle nearer to the preferred trajectory based on the selected parameter.
