<p>PROBLEM TO BE SOLVED: To provide a device for detecting the abnormality of an electric moor regardless of whether a motor relay is connected or not at the time when the device is applied to the ABS motor of mainly an antilock brake device(ABS) and at the same time judging whether the abnormality is due to the downstream disconnection of the motor or due to fixing. SOLUTION: A device judges the generation of an abnormality by combining a fist motor monitor signal for detecting a voltage at the upstream of an ABS motor 1 via a low-pass filter 10 and a second motor monitor signal for detecting the brush noise of the ABS motor 1 via a high-pass filter 11, thus properly detecting the abnormality due to the disconnection of the downstream of the ABS motor 1 and the fixing of the ABS motor 1.</p> |
