Abstract (en)
[origin: WO2022248782A1] The invention relates to a method, implemented in an engine control device of a vehicle, of limiting a correction of at least one parameter, said correction being performed by several adaptation values, the method comprising the following steps: - calculating (10), for every adaptation value, an individual impact value indicating the impact said adaptation value has on the at least one parameter for a current operating point of the engine; - calculating (12) an overall impact value of the impact of all the adaptation values on said at least one parameter for the current operating point of the engine; - comparing (14) the calculated overall impact value with at least one predefined overall impact threshold value; - calculating (16), depending on the result of the comparison, a reduction factor to be applied to the adaptation values; and - applying (18) the calculated reduction factor to each of the adaptation values, thereby providing a set of reduced adaptation values.
