Abstract

Methods, systems, and vehicles are provided pertaining to the determination of a temperature of a vehicle motor having an ignition when the ignition is turned on following a period of time in which the ignition had been turned off. A memory stores a function having a boundary condition that comprises a prior temperature from when the ignition was turned off. A processor is coupled to the memory. The processor is configured to determine an amount of time for which the ignition has been turned on and determine the temperature of the motor using the function if the amount of time for which the ignition has been turned on is less than a predetermined threshold.
