<p><P>PROBLEM TO BE SOLVED: To avoid a voltage of a power source device from being largely descended when two electric motors connected to the same power source device are operated according to the same operation instruction. <P>SOLUTION: When the electric motor is started, a large starting current flows. The maximum value of the starting current is larger than a current flowing at true operation of the electric motor, and the maximum value becomes larger when ability of the electric motor (the maximum value of the current flowing at the true operation) is large as compared with the smaller case. When a shift instruction position is changed between a parking position and the position other than the parking, when both electric motor of an electric parking lock mechanism and an electric motor of an electric parking brake mechanism are operated, they are started at the different timing such that the time when the starting currents become the largest is not overlapped. As a result, a large amount of the current of the power source is consumed, and generation of the large voltage drop is avoided. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
