Abstract: A motorized system includes a motor that drives rotation of an input shaft, a first gear system coupled with the input shaft, a spindle drive, and a measuring arrangement. The spindle drive has a driving element that is coupled with the first gear system, such that rotation of the input shaft prompts rotation of the driving element via the first gear system, and a driven element that is engaged with the driving element, such that rotation of the driving element drives axial movement of the driven element. The measuring arrangement includes a second gear system coupled with the input shaft, an indicator coupled with the second gear system, such that rotation of the input shaft prompts rotation of the indicator via the second gear system, and at least one limit switch with which the indicator interacts to control operation of the motor.

Abstract: A method of determining the electrical resistance of an actual harness connecting the Engine Control Unit (ECU) to a solenoid valve. The method includes providing a dummy harness connected at one end to the ECU and at the other end to a terminal connection in the vicinity of the solenoid valve. The method also includes determining the estimated RMS current through the actual harness and passing a current through the dummy harness such that the heat exchange to the environment is substantially the same as the actual harness. Power consumption of the dummy harness is measured and resistance of the actual harness is determined from estimated RMS and power consumption of the dummy harness.
