Abstract
A method for steady on-chip operation during an automotive thermal malfunction is described. The method includes monitoring a cooling system of a system-on-chip (SoC) during operation of a vehicle control sub-system. The method also includes detecting a thermal failure of the cooling system in response to the monitoring. The method further includes activating a lower power mode of the SoC in response to the detecting of the thermal failure. The method also includes switching to a manual vehicle control.
Claims20
A method for steady on-chip operation during an automotive thermal malfunction, the method comprising:
- monitoring a cooling system of a system-on-chip (SoC) during operation of a vehicle control sub-system;
- detecting a thermal failure of the cooling system in response to the monitoring;
- activating a lower power mode of the SoC in response to the detecting of the thermal failure;
- and
- switching to a manual vehicle control.
A vehicle system, comprising:
- a vehicle control sub-system;
- one or more processor cores coupled to the vehicle control sub-system;
- a heat exchanger (HX) coupled to the one or more processor cores through a coolant pump;
- and
- a thermal safety sub-system to activate a lower power mode of the vehicle control sub-system in response to detection of a thermal failure of the HX and/or the coolant pump.
