Document Type and Number:
Japanese Patent JP7145435
Kind Code:
B2
Abstract:
To simplify a configuration of a cutoff circuit diagnosis device, etc., for diagnosing multiple cutoff circuits which cut off electrification to motors.SOLUTION: A cutoff circuit diagnosis device 10 is configured to diagnose multiple cutoff circuits (a first cutoff circuit 3a and a second cutoff circuit 3b) which cut off electrification to one or more motors. The cutoff circuit diagnosis device comprises: a signal output unit 1 which successively outputs multiple cutoff signals for cutting off the electrification to the one or more motors to the multiple cutoff circuits; a compositing circuit 8 which generates a composite signal by compositing multiple monitor signals outputted respectively from the multiple cutoff circuits; and a diagnosis unit 9 which diagnoses the multiple cutoff circuits on the basis of the composite signal.SELECTED DRAWING: Figure 1
