Abstract:
An automatic calibration method capable of adapting the set of conditions for performing hardware diagnostics, in an OBD system, with a view to optimising the compromise between the number of diagnostics performed, in particular in order to comply with legislation relating to the ratio between the number of diagnostics performed on a component and the number of operating cycles, and the accuracy of the diagnostics.

Claim (Index 1):
A method for establishing an on-board hardware diagnosis on board a vehicle, by way of a suitable computer executing the following steps:\n i. calculating a ratio corresponding to the ratio between a number of instances of a diagnosis, corresponding to the number of times said diagnosis has been performed, and a number of running cycles of the vehicle, corresponding to the number of times said vehicle has had its engine started and has made at least one journey while fulfilling predetermined conditions of use, ii. defining a configurable level of accuracy of the on-board hardware diagnosis, corresponding to one or more conditions for performing said diagnosis, said conditions being linked to a state of the vehicle, based on at least one of a coolant temperature or a speed of the vehicle, and said level of accuracy being able to adopt a plurality of values in steps between a minimum level of accuracy and a maximum level of accuracy, said level of accuracy being able to be increased step by step, as far as the maximum level of accuracy, or reduced step by step, as far as the minimum level of accuracy, iii. upon each new running cycle of the vehicle:\n if said ratio is higher than a predetermined threshold plus a first margin, increasing the level of accuracy by one step, unless said level of accuracy is equal to the maximum level of accuracy, and \n if said ratio is lower than said predetermined threshold plus a second margin, the second margin being smaller than the first margin, reducing the level of accuracy by one step, unless said level of accuracy is equal to the minimum level of accuracy, and \n iv. performing the on-board hardware diagnosis under the performance conditions corresponding to the level of accuracy.
