Automotive safety integrity level classifications for systems hosted by lower-integrity hardware

A computer-implemented method executed on first data processing hardware having a first safety integrity level (SIL) classification, wherein execution of the computer-implemented method by the first data processing hardware causes the first data processing hardware to perform operations comprising:

• executing a monitoring module for monitoring execution of a software module, the software module executing on second data processing hardware having a second SIL classification lower than the first SIL classification;
• detecting a fault condition associated with the software module or the second data processing hardware;
• and
• based on detecting the fault condition, performing a remedial action for the software module or the second data processing hardware to increase an SIL classification of the software module.

A system comprising:

• first data processing hardware having a first safety integrity level (SIL) classification;
• and
• first memory hardware in communication with the first data processing hardware and storing instructions that, when executed by the first data processing hardware, cause the first data processing hardware to perform operations comprising:
• executing a monitoring module for monitoring execution of a software module, the software module executing on second data processing hardware having a second SIL classification lower than the first SIL classification;
• detecting a fault condition associated with the software module or the second data processing hardware;
• and
• based on detecting the fault condition, performing a remedial action for the software module or the second data processing hardware to increase an SIL classification of the software module.
