Abstract
System and method for processing a safety signal in an autonomous vehicle. Safety signals are typically generated in response to the detection of unsafe conditions or are sent by the vehicle operator. In either case, the safety signals are conveyed using redundant communication paths. The paths include a computer network and a current loop. The safety signals are processed, thereby causing actuators (e.g., linkages) to manipulate input devices (e.g., articulation controls and drive controls, such as a throttle, brake, tie rods, steering gear, throttle lever, accelerator, or transmission shifter). The manipulation ensures the vehicle responds appropriately to the safety signals, for example, by shutting down the vehicle.
