Abstract
An abnormality detecting device for detecting a breakage in wiring of a rotation sensor. When the rotating acceleration calculated based on signals from the rotation sensor is greater than a predetermined acceleration value and the rotating speed calculated based on signals from the rotation sensor is zero, a detection signal is put on a wire connected to the rotation sensor. A change in the level of the detection signal is checked for determining whether the rotation sensor is abnormal, i.e., whether there is a breakage in the rotation sensor.
