Abstract: A blending steering control method includes estimating a handwheel pressure applied by an operator to a handwheel and receiving a handwheel torque input indicating a torque value applied by the operator to the handwheel. The method also includes receiving a target handwheel angle indicating a target handwheel angle of an electronic power steering system configured to control a corresponding vehicle along a defined path. The method also includes generating a scaled operator intent value based on the estimated handwheel pressure and the handwheel torque and generating an output torque value based on the target handwheel angle and scaled operator intent value. The method also includes selectively controlling vehicle trajectory based on the output torque value.

Abstract: One or more embodiments are described for facilitating a vision based active steering system. An example steering system includes a handwheel actuator that generates a first feedback torque based on road surface forces at a roadwheel. The steering system further includes a controller that receives, from an image-based system, a control signal indicative of a type of road surface based on an image of the road surface. Further, in response, the controller adjusts one or more parameters of the handwheel actuator to generate a second feedback torque based on the road surface forces at the roadwheel.

Abstract: A method for controlling a steering system of a vehicle is provided. The method includes receiving a measured hand wheel torque signal indicating a measured hand wheel torque of the steering system. A desired hand wheel torque signal is generated, the desired hand wheel torque signal being indicative of a desired hand wheel torque for the steering system. A hand wheel torque tracking error signal based on the measured hand wheel torque signal and the desired hand wheel torque signal is then calculated. To adjust an amount of motor torque applied to the steering system, a desired compensation torque signal is generated based on the hand wheel torque tracking error signal multiplied by a calibration constant.
