Method for controlling the operating condition of a vehicle based on an onboard diagnostic strategy defining different types of failures
First Claim
1. A method of monitoring operation of a vehicle, comprising:
- executing, on each of a vehicle usage cycle, at least one diagnostic phase applied to at least one computer out of electronic computers for monitoring an operation of the vehicle, during which the computer produces and consumes data items, at least one of the data items able to assume a particular predetermined value following detection of an operating failure by the computer, so as to indicate a diagnostic result associated with the failure; and
storing at the end of each vehicle usage cycle a particular value indicative of the failure concerned and initializing a diagnostic phase at a start of a next vehicle usage cycle with the particular stored value so as to reproduce, for the failure concerned, the diagnostic result supplied by the diagnostic phase when it was last executed.

Abstract
A method for controlling an operating condition of a vehicle including executing, at each of operating cycles, at least one diagnostic phase applied to at least one computer controlling an operating condition of the vehicle, during which the computer produces and consumes data, at least one of the data capable of taking a particular predetermined value resulting from detection of an operating failure by the computer, so as to indicate a diagnostic result associated with the failure. The method stores, at the end of each cycle, the particular value for the failure concerned and initializes the diagnostic phase at the beginning of the next operating cycle with the stored particular data so as to reproduce, for the failure concerned, the diagnostic result supplied by the diagnostic phase when it was last executed.

8. A method of monitoring operation of a vehicle comprising:
-
detecting a first change in a vehicle failure state using at least one computer during at least one diagnostic phase of a first vehicle usage cycle; confirming the first change in the vehicle failure state using the at least one computer; defining a first data value corresponding to a first vehicle state resulting from the first change in the vehicle failure state; storing the first data value in a first non-volatile memory, wherein the first data value stored in the first non-volatile memory can only be changed by a subsequent confirmed detection of a second change in the vehicle failure state; and initializing operation of the vehicle at a beginning of a second vehicle usage cycle using the first data value stored in the first non-volatile memory. - View Dependent Claims (9, 10, 11, 12, 13, 14)
