Abstract

An on-vehicle breakdown-warning report system is disclosed. an occurrence of break-down is detected and judged based on a signal in an electronic control system installed on a control apparatus for an engine ignition system, a charging system, an engine fuel system, a engine cooling system, a power transmission system, and an oil lubricating system of an automobile or a diagnosis display system; and a diagnostic data is sent to an information terminal device of a diagnosis and maintenance agency or a service company having a diagnosis and maintenance agency as a contents information by using an on-vehicle mobile communication apparatus, and an action for an emergency measures and a maintenance schedule is asked.

Claims

1. An on-vehicle breakdown-warning report system, wherein:

diagnostic data indicative of an occurrence of break-down detected are collected and are judged based on a signal in an electronic control system or a diagnosis display system installed on a control apparatus, for an engine ignition system, a charging system, an engine fuel system, an engine cooling system, a power transmission system, and an oil lubricating system of an automobile;

said diagnostic data and a current position are sent to an information terminal of a plurality of vehicle diagnosis and maintenance agencies, or to a service company having a plurality of diagnosis and maintenance agencies as a contents information, via an on-vehicle mobile communication apparatus, and a break-down diagnosis is requested;

a running pattern to acquire data used for the break-down diagnosis based on said diagnostic data is received from said diagnosis and maintenance agencies, and is displayed; and

a running test according to the running pattern is instructed to a user.

2. A break-down diagnosis and maintenance diagnosis system for a vehicle, wherein:

control data for a powertrain and vehicle control system in a designated operation condition is compared with an allowable zone for a normal operation condition;

when a break-down diagnostic processing program installed in the vehicle provides a diagnostic report indicating that the control data is located outside said allowable zone, the break-down diagnostic processing program outputs diagnostic data recording a history reaching an abnormal data;

the diagnostic data is transmitted to a server via a mobile data communication terminal; and

when it is not possible to perform the break-down diagnosis based on the received diagnostic data in said server, a running test pattern is produced to collect data for the break-down diagnosis, and is transmitted to said vehicle to instruct the running test.

3. A server system for receiving and processing data through a network or a public circuit, wherein:

the server system includes a vehicle information data base for storing diagnostic data received from a wireless communication system installed on a vehicle, and judges whether it is possible to perform a break-down diagnosis based on past and present diagnostic data; and

if it is not possible to perform the break-down diagnosis, a running test pattern is produced to collect data for break-down diagnosis, and is transmitted to said vehicle to instruct the running test.

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

an abnormal data detection apparatus for detecting abnormal data based on a control data in a designed operation condition for component parts forming a control system including powertrain control and vehicle control and a control data in an ordinary operation condition;

an on-vehicle mobile data communication terminal;

a maintenance information acquisition apparatus for sending a control data or a diagnostic data for said component part, requesting a maintenance information to a maintenance agency outside a vehicle, and acquiring a maintenance information from the maintenance agency, when the abnormal data is detected by said abnormal data detection apparatus; and

when a running test pattern is received to collect data for a break-down diagnosis produced by the maintenance agency, the running test pattern is displayed to instruct the running test.
