<P>PROBLEM TO BE SOLVED: To provide a control device which has low power consumption and is secured in durability and reliability. <P>SOLUTION: Since a power source voltage is changed according to fluctuation in a command current value of each axis (shock absorber), the total power loss of the axis (shock absorber), in other words, heat emitted from each of solenoid drive circuits 18 to 21 is greatly reduced compared with control by a conventional control device. As a result, the power consumption of a suspension system is greatly reduced. Since the heat emitted from each of the solenoid driving circuits 18 to 21 is greatly reduced, the durability and the reliability of the solder part of a substrate, and consequently the durability and the reliability of the suspension system are improved. <P>COPYRIGHT: (C)2013,JPO&INPIT |
