초록 ▼

This invention relates to a fault diagnosis apparatus for a vehicle control system. The fault diagnosis apparatus is useful in diagnosing a fault of an electronic component mounted on a vehicle, especially when the fault has led to such a control as deteriorating exhaust gas. It is an object of this invention to minimize an increase in the manufacturing cost upon incorporation of such a fault diagnosis apparatus. According to this invention, the vehicle control system has an automatic transmission operation state detection sensor, an engine operation state detection sensor, an automatic transmission control unit and an engine control unit. For the diagnosis of a fault of at least one of the sensors and control units, the fault diagnosis apparatus comprises a fault determining unit, a code converter, a fault determining unit, a code converter, an ISO converter and a determining and diagnosing tester.

대표청구항 ▼

A fault diagnosis apparatus for a vehicle control system having: first operation state detection means for detecting the state of operation of a desired first element out of vehicle-constructing elements mounted on a vehicle, second operation state detection means for detecting the state of operation of a desired second element out of said vehicle-constructing elements, said desired second element being different from said first element, a first control unit for controlling said desired first element on the basis of an output from said first operation state detection means, and a second control unit for controlling said desired second element on the basis of an output from said second operation state detection means, whereby a fault of at least one of said first operation state detection means, said second operation state detection means, said first control unit and said second control unit is diagnosed, which apparatus comprises: first fault detection means arranged in association with said first control unit to detect a fault of at least one of said first control unit and said first operation state detection means, first fault signal output means arranged in association with said first control unit to output to said second control unit a fault detection signal, which has been received from said first fault detection means, as a fault signal specific to said first control unit; second fault detection means arranged in association with said second control unit to detect a fault of at least one of said second control unit and said second operation state detection means; second fault signal output means arranged in association with said second control unit to output a fault detection signal, which has been received from said second fault detection means, as a fault signal specific to said second control unit; converter means arranged in association with said second control unit to receive the fault signal from at least one of said first fault signal output means and said second fault signal output means and then to convert said fault signal into a signal which conforms with a predetermined communication system; first determining and diagnosing means for reading the fault signal so converted, thereby determining and diagnosing the fault of at least one of said first control unit, said first operation state detection means, the fault of said second control unit and said second operation state detection means; and second determining and diagnosing means for reading a fault signal from said first fault signal output means to determine and diagnose a fault of said first control unit or said first operation state detection means.
