Patent ID: 8766562

Claim:
A method of temperature-dependent regulation of energization of an adjusting device for adjusting a relative rotational angle position of a first shaft and a second shaft using an adjusting gear configured as a multi-shaft gear, comprising a driving part connected to the first shaft; a driven part connected to the second shaft; an electric servomotor having a servomotor shaft and temperature sensor; an adjusting shaft connected to the servomotor shaft of the electric servomotor in a rotationally fixed manner; and a control unit having a regulator for energizing the servomotor as a function of temperature determined by the temperature sensor, the method comprising the following steps: determining a temperature value in the adjusting device via the temperature sensor; comparing the temperature value with deposited temperature limit values, which distinguish different operation modes of the servomotor from one another; and regulating a current or a pulse-duty factor of the servomotor as a function of a result of the step of comparing to operate the servomotor in the operation modes.
