1. A human body detection method for detecting a human body in a vehicle, comprising:
- detecting chest motion associated with breathing and obtaining a breathing motion signal representing said chest motion in the form of an electrical signal;
detecting times at which specific points occur in a waveform of said breathing motion signal; and
detecting the presence of a human body in said vehicle when time interval between said specific points is within a predetermined range.

Abstract
Chest motion associated with breathing is detected to obtain a breathing motion signal representing the chest motion in the form of an electrical signal; then, the times at which specific points occur in the waveform of the breathing motion signal are detected and, when the time interval between the specific points is within a predetermined range, the presence of a human body is detected in a vehicle.
