A sudden steering detection circuit 2 outputs a sudden steering signal when the angle change exceeds a predetermined value, and a clock pulse is generated from a clock generation circuit 3 that counts the sudden steering signals and outputs them at predetermined intervals. A counter 4 that outputs an alarm signal when the counted value is reset and the counted value becomes, for example, 2, and an alarm unit 5 that issues an alarm based on the alarm signal (the alarm may be a sound, audio, or visual display). In a configuration with a margin of 3 degrees or more, the counter 4 is connected to the clock generation circuit 3.
The sudden steering signal is counted at a predetermined time interval, which is the generation interval of the clock pulse output from the controller.
