摘要： A controller applies slight rotational torque to a drive gear of a reduction mechanism also in a predetermined range in which a motor does not produce any steering operation assist force. That is, the motor is caused to produce slight rotational torque not enough to drive a driven gear, and the rotational torque direction is reversed under a given condition. Accordingly, a backlash between the drive gear and the driven gear is eliminated.

The system is adapted to effect open-loop control by controlling the lamp output according to a predetermined lamp output control pattern until the thermometer reaches a specified temperature range enabling closed-loop control and not lower than the lowest temperature measurable by the thermometer, to compare the gradient of temperatures measured by the thermometer with the gradient of the target temperature control pattern to determine the ratio of the former to the latter after the output of the thermometer has reached the temperature range, to continue the open-loop control while the gradient ratio is smaller than a predetermined control change-over reference value, and to perform closed-loop control by controlling the lamp output after the gradient ratio has increased to not smaller than the reference value so that the temperature measured matches the target temperature control pattern.
