    Abstract: Systems and methods are provided for testing a first computer device of a vehicle. A method includes selecting an operational component of the first computer device and selecting a test operation that is configured to utilize an entire capacity of the operational component. The method further includes instructing the first computer device to perform the test operation and to generate a first result. The method further yet includes retrieving a second result of the test operation and comparing the first result of the test operation from the first computer device with the second result. The method further yet includes indicating that the first computer device is faulty based at least in part on a difference between the first result and the second result.

    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.
