On-vehicle breakdown-warning report system

A vehicle break-down diagnosis and maintenance diagnosis system, wherein

• by comparing control data of a powertrain and vehicle control system in a designated operation condition with an allowable zone for a normal operation condition, when a break-down diagnostic processing program installed in a vehicle provides a diagnosis result indicating that said control data is located outside said allowable zone, said diagnosis result is reported to a driver with an on-vehicle display panel;
• said break-down diagnostic processing program outputs a diagnostic data card recording a history reaching an abnormal data, and transmits said diagnostic data card via a mobile data communication terminal to an information terminal of a service company having a plurality of maintenance agencies, as content information;
• said service company receives said diagnostic data card, collects responses from said maintenance agencies, including estimates for exchanging of parts and investigation and maintenance, and whether or not inspection and measurement is necessary based on said diagnostic data card and a current position, and transmits the collected responses together with position information of respective maintenance agencies;
• and
• said system receives said responses of said maintenance agencies and displays navigation information for travel to the maintenance agency, based on a position information of the maintenance agency, for ordering maintenance and inspection.

An on-vehicle breakdown-warning report system, comprising:

• a break-down diagnosis apparatus for outputting a diagnostic result based on control data for a control system including powertrain control and vehicle control in a designated operation condition, and control data for an ordinary operation condition;
• an on-vehicle panel for displaying a diagnostic result from said break-down diagnosis apparatus for individual component parts of said control system;
• and
• a memory apparatus for storing control data for individual component parts, or diagnostic data, as a diagnostic result obtained by comparing said control data with an allowable range;
• an on-vehicle mobile data communication terminal;
• a vehicle maintenance selection apparatus;
• and
• a maintenance information acquisition apparatus for,
• when a component part is specified on said on-vehicle panel, sending control data or diagnostic data for said component part, requesting maintenance information, estimate information regarding for changes required for inspection and maintenance work, and position information regarding respective maintenance agencies, to plural maintenance agencies outside a vehicle, and acquiring maintenance information individually from said plural maintenance agencies;
• for displaying acquired plural maintenance information and estimation information;
• and
• for receiving as an input a selection of a maintenance agency to which a maintenance work is ordered based displayed maintenance information and estimation information, and
• displaying navigation information for travel to the selected maintenance agency based on the position information of the selected maintenance agency.

A server system for receiving and processing a data through a network or a public circuit comprising a vehicle information data base which stores a diagnostic data card received from a wireless communication system installed on plural vehicles, and a maintenance agency information data base in which information on the maintenance agency and service providing conditions are stored;

• wherein:
• when said server system receives the diagnostic data card from said vehicle a break-down diagnosis is performed based on a history of a diagnostic result for the vehicle, the received diagnostic data card, and diagnostic data card for the vehicle stored in said vehicle information data base;
• said server system stores an answer regarding a necessity for maintenance, an estimate for renewal parts and inspection and maintenance work, and a necessity for inspection and measurement obtained on the basis of the diagnostic result in said vehicle data card;
• and
• said server system sends information concerning a maintenance agency adapted to the service providing conditions to the vehicle.
