A heated wiper system includes a wiper blade with a resilient wiper element having a passage along the wiper element from an opening at one end of where a heating element is inserted into the passage. The temperature of the heating element is controlled by controlling the current supplied to the element by a control unit contained either in the engine compartment or in a recess on the wiper blade. The control unit uses an algorithm including wiper blade and outside ambient temperature, wind chill, ignition on, motor running, heating element resistance value and wipers and varies the current supplied in dependence on a value of the resistance of the heating element. |
