    Abstract: A method of controlling an electric power steering system of a vehicle is provided. The method estimates steering rack force to be caused by a tire of the vehicle and a surface of a ground with which the tire is in contact in response to determining that one or more hand wheel torque sensors of the vehicle are not enabled. The method generates a steering assist torque command based on the estimated steering rack force. The method controls the electric power steering system using the steering assist torque command.

    Abstract: A steering system includes a motor, and a processor configured to perform a method. The method includes computing, by a processor, a predicted steering angle at a future time step. The method further includes determining, by the processor, a predicted vehicle-position at the future time step based on the predicted steering angle. The method further includes detecting, by the processor, a proximity to an object at the future time step based on predicted vehicle-position. The method further includes generating, by the processor, an intervention signal in response to the proximity being below a predetermined threshold.

    Abstract: A steer-by-wire system includes a transmission torque sensor, a handwheel position sensor, and a controller. The transmission torque sensor is configured to measure and output a transmission torque signal. The handwheel position sensor is configured to measure and output a handwheel position signal. The controller includes an angle-based load calculation submodule, a torque steer ratio calculation submodule, and a torque control module. The angle-based load calculation submodule is configured to transform the transmission torque signal and the handwheel position signal into an estimated second load value. The torque steer ratio calculation submodule is configured to transform the estimated second load value, a first load value indicative of roadwheel load including torque steer influence, and the transmission torque signal into a torque steer ratio. The torque control module is configured to transform the first load value, the handwheel position signal, and the torque steer ratio into a handwheel torque command signal.

    Abstract: Technical solutions are described for disturbance feedforward compensation technique for improving the disturbance rejection properties of a closed loop position control system using a cascaded control structure with an inner velocity and outer position control loops. According to one or more embodiments, a system includes a position controller that receives an input rack-position command, and a measured rack-position, and computes a velocity command based on a difference in the input rack-position command and the measured rack-position. The system further includes a velocity controller that receives the velocity command, and a measured motor velocity, and computes an input torque command based on a difference in the velocity command and the measured motor velocity. The system adjusts a position of a rack by generating an amount of torque corresponding to the applying the input torque command to a motor.

    Abstract: A collision avoidance system for a vehicle includes at least one sensing device for detecting one or more obstacles proximate the vehicle. Also included is a model predictive control module for determining a predictive model path to avoid a collision with one or more objects during a lane change maneuver of the vehicle. Further included is a steering system receiving a steering angle command from the model predictive control module for automatically controlling the steering system to steer the vehicle along the predictive model path.

    Abstract: A vehicle safety system includes a controller in communication with at least one of an imaging system and a ranging system. At least one of the imaging system and the ranging system being arranged to monitor a distance and a speed of a forward vehicle and an incoming vehicle relative to a host vehicle. The controller is programmed to output for display a time left to pass the forward vehicle based on the distance and the speed of the forward vehicle and the incoming vehicle, responsive to indicia of an impending host vehicle maneuver to pass the forward vehicle.
