<p><P>PROBLEM TO BE SOLVED: To provide a vehicle sharing system for securing the reliability of time information of a vehicle, and for carrying out an accurate vehicle lending process and a vehicle returning process by the vehicle itself. <P>SOLUTION: When a port arriving vehicle reaches a port, a control part of the port arriving vehicle carries out simultaneous multiple address of current time information by an internal clock along with adjustment date and time of the time information stored in a storage to all port parked vehicles parked in the port that has been reached by using a short range communication device (S5). In the port parked vehicle, adjustment date and time of one's current time information stored in a storage of the port parked vehicle is subtracted from the adjustment date and time of the time information received by using a short range communication device, and it is determined whether or not time has passed from a predetermined period (S15). If the result is that time has passed from the predetermined period (YES of S15), a control part of the port parked vehicle updates one's time information and its adjustment date and time by the received time information and its adjustment date and time (S16). <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
