ABSTRACT:
A safety control apparatus positively discriminates between an object and a person through the detection of subtle physical movement corresponding to the heart activity and the breathing unique to the life activity of the human body from a output signal of a vibration sensor disposed on a seat so as to accurately decide whether or not a person is present. The maintenance of the safe operation of the moving vehicle can be realized. The starting of the moving vehicle is inhibited if the reserved seat is determined to be unoccupied in accordance with the decision result. In the case where the person is present, the moving of the vehicle is not started before the engagement of the seat belt has been detected.
