ABSTRACT:
There is provided an apparatus which decides the presence or absence of an anomaly by detecting the gripped state of a steering wheel by the driver steering a road-vehicle, or by measuring fluctuations in heart rate and heartbeat period of the driver, and which issues an alarm of "Take a rest", etc. or controls the vehicle speed to be lowered, if there occurs any anomaly. Detecting means is attached to a steering wheel, steering wheel cover or a band-shaped member. The detecting means comprises a plurality of reflection type optical sensors which are each composed of a light emitting element and one or more light receiving elements, and which are set in such proper arrangement and orientation as permitting detection in any of various conditions.
