Abstract:
1. A system comprising: a primary controller configured to perform functions associated with control of operation of a vehicle including vehicle propulsion, braking and steering; a secondary controller configured in a redundant configuration as the primary controller, wherein the primary controller and the secondary controller are configured to operate based on execution of a first set of logic and perform cross-checks of each other; a control module configured to transfer control of operation of the vehicle between the primary controller and the secondary controller based on a detected fault at one of the primary controller and the secondary controller, wherein the control module is further configured to detect a common fault of the primary controller and the secondary controller and the control module is configured to responsively output a common fault signal; a safety controller coupled to the control module configured to operate based on execution of a second set of logic independent of operation of the primary controller and the secondary controller, and based on receiving the common fault signal the safety controller is configured to receive transfer of control of operation of the vehicle; and to perform functions associated with control of operation of the vehicle including vehicle braking.
