    Abstract: A method of controlling a vehicle having an electric power steering system includes generating a plurality of possible routes. Each of the plurality of possible routes that require a steering torque that is within an available torque range is identified as a system compliant route. Each of the plurality of possible routes that require an angular position of an electric motor of the electric power steering system at all time indices throughout that route that are within an available motor position range are also identified as a system compliant route. One of the identified system compliant routes is selected based on at least one selection criteria, and designated as an active route. The electric power steering system is then controlled to maneuver the vehicle along the active route. The electric power steering system is monitored as the vehicle moves along the active route to identify degradation of its capabilities.

    Abstract: A method of controlling a vehicle includes determining a first projected path of the vehicle, receiving sensor data corresponding to a steering input, determining a first blended vehicle path resulting from a first blended steering command based on the first projected path and the sensor data, and determining when the first blended vehicle path satisfies a first criteria. When the controller determines that the first blended vehicle path satisfies the first criteria, the controller relinquishes control of the vehicle to an operator and when the controller determines that the first blended vehicle path does not satisfy the first criteria, the controller generates a second blended vehicle path resulting from a second blended steering command based on the first projected path and the sensor data.

    Abstract: Methods, systems, and vehicles are provided for controlling steering in an autonomous vehicle including a communication system, a vehicle control system, and a steering control system. The vehicle control system is configured to provide initial steering instructions, via the communication system, that include a current steering command for a current time and one or more future projected steering commands for the autonomous vehicle for possible implementation at one or more future times. The steering control system includes a processor configured to implement the current steering command; determine, subsequent to the initial steering instructions, that an error has occurred with respect to the providing of steering instructions from the vehicle control system; and implement the one or more future projected steering commands for the one or more future times when it is determined that an error has occurred with respect to the providing of steering instructions from the vehicle control system.

    Abstract: An automotive vehicle includes a vehicle steering system, an actuator configured to control the steering system, a first controller, and a second controller. The first controller is in communication with the actuator. The first controller is configured to communicate an actuator control signal based on a primary automated driving system control algorithm. The second controller is in communication with the actuator and with the first controller. The second controller is configured to, in response to a first predicted vehicle path based on the actuator control signal deviating from a desired route by a threshold distance, control the actuator to maintain a current actuator setting. The second controller is also configured to, in response to the first predicted vehicle path not deviating from the desired route by the threshold distance, control the actuator according to the actuator control signal.
