ABSTRACT:

SUMMARY OF THE INVENTION
In an exemplary embodiment of the invention, a steering wheel heating system includes a heating element disposed on a portion of a steering wheel and arranged to receive an electrical current. A sensor is disposed on the steering wheel for generating a signal indicative of the temperature on the steering wheel. A controller is arranged to receive the signal from the sensor, as well as a signal input by the user. Controller controls the electrical current such that said electrical current is proportional to the difference between the user-input value and the steering wheel temperature.
