摘要

On the basis of biorhythm information (42) stored in a storage unit (36), an estimation unit (53) estimates a time indicating the onset of drowsiness. At or before the estimated time, an attention-calling control unit (54) executes control to perform attention-calling output to a driver, control to ease the implementation standards for attention-calling output, or control to increase the degree of attention-calling output.
