Systems, methods and devices for adaptive steering control of automotive vehicles
First Claim
1. A method for providing automated assistive steering of an automotive vehicle to maintain the vehicle along a travel direction within a vehicle lane by providing automated assistive steering relative to a target current vehicle offset for a lateral position relative to the travel direction, the method comprising:
- detecting steering input from a driver that results in a change in the lateral position of the vehicle in the lane relative to the target current vehicle offset;
modifying, in response to steering input from a driver, the target vehicle offset within the vehicle lane according to the change in the lateral position of the vehicle and thereby maintaining the vehicle along a new path in the vehicle lane.

Abstract
A variety of methods, systems, devices and arrangements are implemented for automated assistance for a driver. One such method relates to a synergistic combination of automation and human control for a motor vehicle traveling on a lane, thereby allowing human-based decisions to be supplement (or be supplemented by) automated decisions. Specific aspects facilitate maintenance of the vehicle on the lane. The vehicle is automatically steered towards a lateral offset within the vehicle lane. Steering input from the driver results in changes to this lateral offset. This modification of the lateral offset can be used to allow the driver to follow any trajectory parallel to the road, including trajectories where the vehicle is not centered within the lane.

10. A method for providing automated assistive steering of an automotive vehicle along a travel direction to maintain the vehicle at a target vehicle offset for a lateral position relative to the travel direction within a vehicle lane and for allowing a driver to control where the target offset places the vehicle within the vehicle lane, the method comprising:
-
determining a current vehicle location within the vehicle lane as a function of a current vehicle-position signal; setting, in response to a driver steering input, the target vehicle offset within the vehicle lane relative to the current vehicle location; and generating, in response to an error between a current vehicle-position and the target vehicle offset, a steering trim-adjust signal to facilitate automatic assistive steering for the automotive vehicle. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. For automatic assistive steering of an automotive vehicle operating in a vehicle lane with the vehicle operating responsive to manually-controlled driver steering forces, a computer readable medium containing a set of computer-executable instructions that, when executed, causes a computer in the automotive vehicle to:
-
set, in response to a driver steering input, a target vehicle offset that indicates a lateral position, relative to a direction of travel, within the vehicle lane, wherein the target vehicle offset is relative to the current vehicle location; and generate, in response to an error between a current vehicle-position and the target vehicle offset, a steering trim-adjust signal to facilitate automatic assistive steering for the automotive vehicle. - View Dependent Claims (25)
