Abstract: In a power steering device and a control device for a vehicle-mounted instrument, an abnormality detection accuracy of sensor output signals is increased. In an electric power steering device and a control device for a vehicle-mounted instrument, judgment for the abnormality of the sensor output signals is carried out by using at least four or more sensor output signals, in which when the sensor output signals satisfy both a first condition (viz., the number of the output signals showing an identical value is the largest) and a second condition (viz., the number is equal to or larger than “n+1”) (n=the largest number of the sensor output signals that have a common factor), judgement is so made that the sensor output signals that satisfy the first and second conditions are normal and the other signals are abnormal.
