Method and system of assisting a driver of a vehicle
First Claim
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.

Abstract
A method of assisting a driver of a vehicle. A road to be driven by the driver is identified 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 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.

-
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 the location of a boundary along the road and a preferred trajectory to be driven along the road; 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 applying an assist torque on a portion of a steering system to move the vehicle toward the preferred trajectory based on the selected parameter, the assist torque being calculated using estimated values for a distance of the vehicle to the preferred trajectory, an angle to the preferred trajectory, and a curvature of the preferred trajectory at a predetermined period of time in the future, and the predetermined period of time in the future being based on a speed of the driver'"'"'s steering operation during previous driving maneuvers.
