<p>PURPOSE:To improve the safety by judging the existence of conformity of a motor rotation direction drive signal from a CPU inputting a steering torque signal with a rotation direction drive signal from a motor rotation drive direction judging block, thereby indicating the rotational drive direction of motor. CONSTITUTION:When an output signal from a torque detector 1 is sent through the handle operation of a steering handle, right and left direction drive signals 17B, 17C are output from a torque signal direction judging circuit 17A of a motor rotation drive direction judging block 17, and they are added to a second input end of AND circuits 20A, 20B. The right and left direction drive signals are added to a first input end of the AND circuits 20A, 20B through interface circuits 4, 5. The circuits 20A, 20B transmit the outputs to a motor drive circuit 10 as right an left rotation drive signals when two inputs are in conformity, and indicate the rotation drive direction of a motor 14.</p> |
