Abstract
A portable information terminal controlling system of the present invention comprises the detector-transmitter and the cellular phone. The detector-transmitter includes the automobile moving state detecting unit and the control information transmitting unit. The cellular phone includes the function controlling unit, the transmitter-receiver, the display and the control unit. When the detector-transmitter detects that an automobile is moving, the detector-transmitter sends control information to a function controlling unit. When the detector-transmitter detects that an automobile is moving, the function controlling unit limits a part of a display function and a communication function of a portable information terminal, or limits all functions of the portable information terminal, and makes the portable information terminal be in a difficult state to use by giving an instruction to the control unit. Judgment of the driver'"'"'s use of the portable information terminal is performed based on a signal arriving time and signal strength between the detector-transmitter and the function controlling unit, or an image extract with a camera included in the detector-transmitter.
