1. An information sharing system comprising a plurality of on-vehicle diagnosis terminals, and one or a plurality of display terminals, the on-vehicle diagnosis terminals and the one or the plurality of display terminals comprising a terminal that comprises a communication unit including one of first and second communication units configured to perform peer-to-peer wireless communication,the on-vehicle diagnosis terminals comprising:

  • the first communication unit, and a diagnostic information acquiring unit configured to acquire diagnostic information on an electric vehicle equipped with the on-vehicle diagnosis terminal,the one or the plurality of display terminals comprising;

    the second communication unit, and a display configured to display the diagnostic information on the electric vehicles equipped with the on-vehicle diagnosis terminals,the on-vehicle diagnosis terminals and the one or the plurality of display terminals sharing the diagnostic information on the electric vehicles equipped with the on-vehicle diagnosis terminals over wireless communication among the terminals using the communication units,wherein the on-vehicle diagnosis terminals comprise;

    a first clock unit that keeps a common time that is unified in the information sharing system;

    an own-vehicle data storing unit configured to store one or more own-vehicle data sets that each comprise one or more data sets comprising at least a unique identifier that is uniquely assigned to the on-vehicle diagnosis terminal, the diagnostic information acquired by the diagnostic information-acquiring unit of the on-vehicle diagnosis terminal, and an acquisition clock time in the common time at which the diagnostic information is acquired; and

    an other-vehicle data storing unit configured to store other-vehicle data sets that comprise the data sets on other electric vehicles that are acquired through the first communication unit of the on-vehicle diagnosis terminal,wherein the one or the plurality of display terminals comprise;

    a second clock unit that keeps the common time; and

    a data storing unit configured to store data sets on the electric vehicles that are acquired through the second communication unit of the display terminal,wherein the on-vehicle diagnosis terminals comprise;

    a first communication establishing unit configured to establish peer-to-peer wireless communication with the communication units of the terminals capable of establishing wireless communication with the on-vehicle diagnosis terminal;

    a first newly-storing unit configured to make the other-vehicle data storing unit of the on-vehicle diagnosis terminal store new data sets comprising at least a unique identifier that is not stored in the other-vehicle data storing unit of the on-vehicle diagnosis terminal among the data sets stored in first terminals that comprise the terminals with which the wireless communication is established with the on-vehicle diagnosis terminal;

    a first renewing and storing unit configured to renew and store the one or more data sets that each comprises at least a unique identifier which is the same as the unique identifier of an other-vehicle data set stored in the other-vehicle data storing unit of the on-vehicle diagnosis terminal, and has a newer acquisition clock time among the data sets stored in the first terminals; and

    a first clock time storing unit configured to renew and store, every time a data set stored in each first terminal is stored in the other-vehicle data storing unit of the on-vehicle diagnosis terminal, a first stored clock time in the common time for every first terminal, the first stored clock time being the stored timing,wherein the one or the plurality of display terminals comprise;

    a second communication establishing unit configured to establish peer-to-peer wireless communication with the communication units of the terminals capable of establishing wireless communication with the display terminal;

    a second newly-storing unit configured to make the data storing unit of the display terminal store a new data set comprising at least a unique identifier that is not stored in the data storing unit of the display terminal among the data sets stored in second terminals that comprise the terminals with which the wireless communication is established with the display terminal;

    a second renewing and storing unit configured to renew and store the data sets that each comprise at least a unique identifier which is the same as the unique identifier of the data set stored in the data storing unit of the display terminal, and has a newer acquisition clock time among the data sets stored in the second terminals; and

    a second clock time storing unit configured to renew and store, every time a data set stored in each second terminal is stored in the data storing unit of the display terminal, a second stored clock time in the common time for every second terminal, the second stored clock time being the stored timing,wherein the on-vehicle diagnosis terminals comprise a first determination unit configured to;

    determine, when the peer-to-peer wireless communication is established by the first communication establishing unit, whether or not a first predetermined time has passed from the first stored clock times that are stored in relation to the first terminals with which the wireless communication is established;

    perform, when the first predetermined time has passed, the storing into the other-vehicle data storing units using the first newly-storing units and the first renewing and storing units; and

    establish, when the first predetermined time has not passed, new wireless communication using the first communication establishing units with the communication units of the terminals capable of establishing wireless communication with the on-vehicle diagnosis terminal, andwherein the one or the plurality of display terminals comprise a second determination unit configured to;

    determine, when the peer-to-peer wireless communication is established by the second communication establishing unit, whether or not a second predetermined time has passed from the second stored clock times that are stored in relation to the second terminals with which the wireless communication is established;

    perform, when the second predetermined time has passed, the storing into the data storing units using the second newly-storing units and the second renewing and storing units; and

    establish, when the second predetermined time has not passed, new wireless communication using the second communication establishing units with the communication units of the terminals capable of establishing wireless communication with the display terminal.
