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 host vehicle includes a driver re-engagement assessment system and an X-by-wire device adapted for both manual control and automated control by an automated guidance system. The driver re-engagement assessment system includes a controller, a user interface, and test execution module and a test evaluation module. The user interface is configured to interface with an occupant and output an occupant directive signal for manual control to the controller. The test execution module initiates an occupant re-engagement test upon receipt of the occupant directive signal by the controller. The test evaluation module is configured to receive an occupant performance signal indicative of occupant performance during the re-engagement test, and evaluate the occupant performance signal to determine a test pass result and a test fail result. The manual control of the host vehicle is assumed by the occupant upon the determination of the test pass result.

Abstract: A manual power pack assembly for an electric power steering (EPS) system includes a motor housing at least partially enclosing a motor and having an outer diameter. The manual power pack assembly also includes a connector plate formed of a material comprising plastic, the connector plate having a first side, a second side, and a cylinder extending from the first side. The manual power pack further includes a metal ring disposed on an inner diameter of the cylinder and in contact with the outer diameter of the motor housing.

Abstract: A method for controlling an electronic power steering system may include receiving, at an electronic power steering controller, at least one signal from at least one sensor and generating, by the electronic power steering controller using the at least one signal, a first autonomous steering command. The method may also include receiving, from a domain controller at the electronic power steering controller, a second autonomous steering command and comparing, by the electronic power steering controller, the first autonomous steering command and the second autonomous steering command. The method may also include selectively controlling, by the electronic power steering controller, the electronic power steering system using one of the first autonomous steering command and the second autonomous steering command, based on the comparison of the first autonomous steering command and the second autonomous steering command.

Abstract: A position measurement system for a steering system includes a steering shaft. The position measurement system also includes a worm gear coupled to the steering shaft. The position measurement system further includes a worm in meshed engagement with the worm gear, the worm driven by a motor. The position measurement system yet further includes a first sensor operatively coupled to the worm to detect an angular position of the worm and the motor that drives the worm. The position measurement system also includes a driving gear coupled to the steering shaft. The position measurement system further includes a spur gear in meshed engagement with the driving gear. The position measurement system yet further includes a second sensor operatively coupled to the spur gear to detect an angular position of the spur gear.

Abstract: A method of transitioning from an autonomous driving mode to a manual driving mode for a vehicle is provided. The method includes comparing a steering device input angle to an autonomously controlled steering angle to determine a steering angle error. The method also includes comparing an acceleration or deceleration input to an autonomously controlled acceleration or deceleration input to determine an acceleration or deceleration error. The method further includes progressively transitioning to the manual driving mode in a weighted manner based on a confidence level factor determined by a calculation that factors in the steering angle error and the acceleration or deceleration error.

Abstract: A method for providing operating mode transition for a vehicle includes receiving an input indicating a request to transition from a first operating mode of the vehicle to a second operating mode of the vehicle and determining a first planned trajectory corresponding to the first operating mode. The method also includes determining a second planned trajectory corresponding to the second operating mode. The method also includes determining a first road wheel actuator angle corresponding to the first planned trajectory and determining a second road wheel actuator angle corresponding to the second planned trajectory. The method also includes determining a difference between a current handwheel actuator angle and a handwheel actuator angle corresponding to the second road wheel actuator angle and, in response to a determination that the difference is less than a threshold, transitioning from the first operating mode to the second operating mode over a determined period.
