Abstract

PURPOSE:To prevent shock due to abrupt change in the number of revolutions of a motor by giving a corrective signal for the input to the motor at the point of time the power switch of the car is turned on or off while a torque is being generated on a column shaft. CONSTITUTION:Output signals from output ports B3-B10 of a control part 5 to control the number of revolutions of a motor 13 are entered into a D/A converter 11, and the output signal therefrom is put into a motor driver circuit 12. Regular and reverse rotation signals from another output port B11 and a one B12 and a stop signal emitted from an output port B13 are fed into the abovementioned motor driver circuit 12. A memory 5c of the control part 5 is equipped with a function to read the factor corresponding to the time t from the point when the power switch 2 is turned on or off, and the correction value for the input to the motor is calculated in accordance with this factor, and the result is fed into the motor driver circuit 12. Thus the motor is operated so that the number of revolutions increases by and by.
