Abstract
A method and an apparatus 12 which uses or calculates a temperature gradient of a portion 16 of a vehicle 10 to determine a value equal to or representative of a time before a maximum allowable operating temperature is reached by the portion 16. If the value is less than a certain threshold, the apparatus 12 reduces the operating speed of the portion 16 and, in one embodiment, provides a warning signal to an operator of the vehicle 10.
