Abstract
Systems and methods for detecting hardware faults in computer-based feedback control systems. Multiple instances of the system control program(s) are run on system processors. System sensor data are input to each instance, and the control commands output by each instance are compared. As instantiations of the same programs receive largely the same sensor data, differences between output commands may indicate the presence of one or more hardware faults.
Claims20
An autonomous or semi-autonomous machine comprising:
- one or more central processing units (CPUs);
- one or more graphics processing units (GPUs);
- one or more hardware accelerators;
- and
- one or more sensors having one or more sensory fields external to the autonomous or semi-autonomous machine,
- wherein the autonomous or semi-autonomous machine is to:
- apply different respective sets of sensor data obtained using the one or more sensors to different respective program instances to generate corresponding outputs associated with controlling the autonomous or semi-autonomous machine;
- determine, based at least on a comparison of the outputs, a result corresponding to hardware fault detection;
- and
- perform one or more operations based at least on the result corresponding to hardware fault detection.
