<P>PROBLEM TO BE SOLVED: To properly control the rotation of a DC motor 110 by an electric actuator system. <P>SOLUTION: When an ignition switch IG is turned off in a state that the actual rotational angle of an output shaft 127 of an actuator among actuators 100a to 100e and a rotational angle stored in a memory circuit 402 are different from each other, an electronic control device 400 performs the initial position setting of the correspondent actuator when the ignition switch IG is turned on next. Thus by rotating the output shaft of the correspondent actuator to an original point and stop it thereat, and by storing the fact that the output shaft of the correspondent actuator is rotated to the original point, the rotational angle stored in the memory circuit 402 and the actual rotational angle of the output shaft are made to coincide with each other. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
