| description | PURPOSE: To provide a failure detecting device for an electronic control unit, simple and at a low cost, capable of detecting failure of a control microcomputer without providing a monitoring microcomputer. CONSTITUTION: A device comprises a phase difference setting circuit 12 making a watch dog pulse output from a controlling microcomputer 11 branch into two systems also to set a prescribed periodic difference output between these pulses relating to the two system watch dog pulses and a nonconformity detecting circuit 13 comparing both outputs from the phase difference setting circuit 12 to perform trouble decision by inconformity of both the outputs. |
