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.
