A drive recorder to be mounted on a vehicle includes an acquisition unit, a recording unit, a communication unit, and a control unit. The acquisition unit acquires data representing driving condition. The recording unit records the acquired data. The communication unit transmits the acquired data to the outside. The control unit controls the quality of the data to be transmitted based on the information received from the outside.

A malfunction analysis apparatus () is provided with a malfunction-analysis processor (), an attribute-extraction processor (), and an outputter (). The malfunction-analysis processor () obtains a malfunction-contribution degree, which indicates a degree that individual malfunctions (to be called malfunctioning elements, hereafter) contribute to the malfunctioning of the object being analyzed, on the basis of the relative relationship between the data to be analyzed that has, as elements thereof, values generated on the basis of a plurality of indicator values of the object being analyzed, and representative values for the plurality of indicators corresponding to each of the plurality of malfunctions. Then, the malfunctioning elements being generated is specified, on the basis of the obtained malfunction-contribution degree. The attribute-extraction processor () specifies, when a malfunctioning is taking place that is a combination of the malfunctioning elements, the indicators that are estimated as the cause of the specified malfunctioning elements, on the basis of the representative values of the plurality of indicators, and the values of each of the elements of the data to be analyzed that was stored. The outputter () outputs the specified malfunctioning elements and/or the indicators.

A diagnostic device detects a fault and estimates its cause based on the degree of change of measured data attributes. A diagnostic object change degree pattern (CDP) generation unit calculates the degree of change of each attribute of data, including attributes of the object being diagnosed measured from the object being diagnosed to generate a diagnostic object CDP which is a combination of values of the degree of change of the respective attributes. A criterion CDP memory holds in store a criterion CDP, formed of a pattern of values of the degree of change of the attributes of data measured from the object being diagnosed, in association with event(s)-to-be-diagnosed on the fault sort basis or on the fault cause basis. A CDP diagnosis unit effects pattern matching between the diagnostic object CDP and the criterion CDP in the criterion CDP memory to diagnose the object being diagnosed.

Diagnostic device

The present invention provides a diagnostic system that diagnoses a diagnostic object by applying a diagnostic rule to data measured on the diagnostic object wherein an object of the present invention is to allow the diagnostic rule to be updated based on a variety of diagnostic case data. Each of multiple diagnostic devicesmakes a diagnosis by applying a diagnostic rule to diagnostic object data measured on a diagnostic objectand sends diagnostic case data, which includes diagnostic object data and its diagnostic result, to a diagnostic rule generation devicevia a network. The diagnostic rule generation devicegenerates a diagnostic rule based on the diagnostic case data received from the multiple diagnostic devicesand sends the generated diagnostic rule to the diagnostic devicesvia the network. The diagnostic devicesupdate a diagnostic rule in their devices with the diagnostic rule received from the diagnostic rule generation device
