Abstract: An estimated brake rotor temperature is provided including a cooling effect during active braking as well as when braking is inactive. The cooling effect is based on a difference between the rotor temperature and sensed ambient temperature and is also preferably based on wheel speed. In an active braking mode, a heating effect is provided based at least on sensed wheel speed. If no brake pressure signal is available, the heating effect is further based on vehicle deceleration. The heating effects for front and rear brake units are relatively compensated for differences in heat generation due to load shifts during braking, the compensation being preferably based on vehicle deceleration. The brake rotor temperature estimation is realized in a programmed digital computer but does not use computer resource hungry exponential functions.
