Abstract
An automotive vehicle includes at least one sensor configured to detect features in a region proximate the exterior of the vehicle, at least one actuator configured to control vehicle steering, propulsion, shifting, or braking, and an automated driving system selectively operable in a nominal mode and in a degraded mode. The automated driving system is configured to generate an actuator control signal for the at least one actuator in response to sensor signals from the at least one sensor. The automated driving system includes a computational accelerator processor. The vehicle further includes a monitor processor in communication with the automated driving system. The monitor processor is configured to provide a test input for processing by the computational accelerator processor, receive a test output from the computational accelerator processor, and in response to the test output not satisfying a validation criterion, control the automated driving system in the degraded mode.
