Abstract: The present disclosure relates to an automated system for use in connection with longitudinal deceleration, longitudinal acceleration, and lateral acceleration functions. The system includes an interface receiving signals from and transmitting signals to a controller. The system also includes a safety kernel system comprising safety kernel software and a set of safety rules. Also disclosed are methods for use in a motion control system in connection with vehicle deceleration, acceleration, and lateral acceleration. The methods in some cases include receiving an initial request into a safety kernel software and determining whether the safety kernel software has received an override. The methods can also include detecting a violation of any primary safeguards defined by the safety kernel software, detecting a violation within a set of secondary safeguards defined by the safety kernel software, and adjusting the initial request to a modified level; and transmitting the modified level to an actuator.

Abstract: Systems and methods are provided for effecting control through multi-stage voting. A control system may be in communication with an actuator device responsive to a voted command. A multi-stage voting system may be configured to determine the voted command. A set of controllers and a monitor controller may provide commands to the multi-stage voting system. The multi-stage voting system includes logic with a first stage that compares the commands of the set of controllers to each other, and a second stage that compares at least one of those commands to the monitor command. The multi-stage voting system delivers the voted command to the actuator device based on the comparisons made in the first and second stages. The actuator device effects an operation in response to the voted command.
