Abstract
In a control device, control circuit units are connected to separate circuit power sources and to separate grounds. Ground monitor circuits respectively have a first resistor with one end connected to a voltage source, a second resistor with one end connected to an input terminal of a corresponding control circuit unit, and a capacitor. Among the one end of the first resistor, an other end of the first resistor, and the other end of the second resistor, at least one is connected to the subject system, and at least one is connected to an other system, and the control circuit unit monitors a ground abnormality of the other system based on a terminal voltage of the input terminal to which the second resistor is connected.
