Title:
DEVICE FOR DRIVING/CONTROLLING BIDIRECTIONAL ACTUATOR
Document Type and Number:
Japanese Patent JPH07224563
Kind Code:
A
Abstract:

PURPOSE: To provide a device for driving/controlling a bidirectional actuator suitable for an automobile wherein the number of relays for drive control of a large number of bidirectional actuators in forward and reverse directions can be reduced.

CONSTITUTION: If one of operating means 31-3n is operated in forward and reverse directions, actuator relays 20a1-20n of corresponding bidirectional actuators are operated so that a first drive source line La is connected to the other end of the bidirectional actuator. And a first relay 20b or a second relay 20c is operated so that the first drive source line La or a second drive source line Lb is connected to a + terminal of a direct-current source 4, wherein the second relay 20c or 20b is in a non-acting state and the second drive source line Lb is connected to an earth terminal of direct-current source, and hence terminals of the direct-current source connected to the opposite ends of actuator are switched over.
