Abstract
Method for determining a present coil temperature of a coil of a magnetorheological (MR) damper of an operating automotive vehicle, wherein the coil is powered by an output of a controller connected to the coil through a conductor. One step includes calculating a coil-plus-conductor resistance from the voltage and the current of the output of the controller when the controller applies a test current to the coil and the conductor. Another step includes calculating the present coil temperature using at least the coil-plus-conductor resistance and compensating for the resistance of the conductor.
