Electric driver device

Abstract

An electric driver device provides a partial redundancy system that is at least partially redundant, or a full redundancy system. The electric driver device has a plurality of circuit systems. The electric driver device includes, in at least a part of the electric circuit, a common circuit extending over at least two of a plurality of circuit systems. The common circuit includes a power supply and/or a connection line that complements signals. At least one of the power supply circuit, an interface circuit, a power supply cutoff circuit, and a connector is not separated and independent from each other for each redundant circuit system.

What is claimed is: 
     
         1 . An electric driver device, comprising:
 a motor for driving an object to be driven; and   an electric circuit including a plurality of circuit systems for controlling the motor; and   at least two connectors having a plurality of electrodes for connecting a power supply and a plurality of input/output signals, wherein   the plurality of electrodes are asymmetrically arranged on the plurality of connectors.   
     
     
         2 . The electric driver device claimed in  claim 1 , wherein
 the plurality of electrodes for the input/output signals are arranged in an intensive manner for each function in the plurality of connectors.   
     
     
         3 . The electric driver device claimed in  claim 2 , wherein
 the electric circuit has a plurality of redundant circuit systems, and wherein   each of the plurality of circuit systems includes:   the connector;   the power cutoff circuit provided between the connector and the motor, which cuts off and connects the power supply;   the power conversion circuit which controls power supplied from the power supply to the motor;   the interface circuit which processes the plurality of input/output signals;   the drive circuit which outputs a drive signal for the power cutoff circuit and the power conversion circuit;   the arithmetic processing unit circuit which calculates a control amount in accordance with the input/output signal processed by the interface circuit and controls the drive circuit; and   the power supply circuit which supplies power to the arithmetic processing unit circuit and the interface circuit.   
     
     
         4 . An electric driver device, comprising:
 a motor for driving an object to be driven;   an electric circuit including a plurality of circuit systems for controlling the motor; and   an odd number of connector having a plurality of electrodes for connecting a power supply and a plurality of input/output signals.
