<p><P>PROBLEM TO BE SOLVED: To actualize parking setting by actuating an SBW actuator with less electric power without controlling the energization of an electric motor mounted on the SBW actuator. <P>SOLUTION: A forcible parking energizing means energizes the electric actuator 94 with electric power accumulated in a capacitor during a power supply failure when predetermined operation is done. Then, a rod locking mechanism 82 is unlocked and the energizing force of a spring 85 drives a rod 84, a flange 33 and an output shaft 17 to establish a locked state (a parking state) with a parking change-over mechanism. Slight power consumption is used as a trigger for parking setting with the energizing force of the spring 85, therefore less electric power is required during parking setting and the size and cost of the capacitor are reduced. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
