Adaptive self-heating management of processors in autonomous vehicles

A vehicle, comprising:

• a processor to execute one or more compute operations;
• a temperature sensor to sense a temperature of the processor and output temperature data samples over time;
• and
• a control processor to:
• receive the temperature data samples;
• determine a temperature profile line that fits the temperature data samples;
• determine a regression profile based on one or more parameters defining the temperature profile line;
• determine one or more compensation actions that modifies one or more of:
• the processor and the vehicle;
• and
• trigger the one or more compensation actions to be performed,
• wherein the one or more compensation actions comprises:
• allowing the vehicle to complete a current operational assignment;
• and
• after the vehicle completes the current operational assignment, changing a route of the vehicle.

A computer-implemented method, comprising:

• receiving one or more parameters defining a temperature profile line representative of a relationship between a temperature of a processor of a vehicle and time;
• determining an estimated time to a critical temperature based on a critical temperature point on the temperature profile line;
• determining an estimated time for the vehicle to complete a current operational assignment;
• based on the estimated time to the critical temperature and the estimated time for the vehicle to complete the current operational assignment, determining one or more compensation actions to be performed by the vehicle;
• triggering the one or more compensation actions to be performed,
• wherein the one or more compensation actions comprises:
• allowing the vehicle to complete a current operational assignment;
• and
• after the vehicle completes the current operational assignment, changing a route of the vehicle.
