Process for the adaptive control of an internal-combustion engine and/or another drive component of a motor vehicle

Claim 1

A process for adaptive control of a drive component in a motor vehicle having an internal-combustion engine, the drive component having a critical time interval with respect to a controlled variable for a predefined operating behavior of the drive component at selected operating points, the process comprising the steps of: detecting an occurrence of a non-steady operating state of the drive component using a detection means (59); obtaining a selected set value for the critical time interval from a memory means (91) upon detecting said non-steady operating state for one of the selected operating points, said memory means storing a first characteristic map of set values assigned to the selected operating points of the internal-combustion engine including speed and load information on the selected operating points; obtaining an actual value for the critical time interval from a measuring means (67) upon detecting said non-steady operating state for the one selected operating point; comparing said selected set value with the actual value in a comparison means (73) and determining whether any deviation exceeds a threshold value; calculating a selected updated correction value for controlling the controlled variable with regard to the predefined operating behavior using an arithmetic means (99) if said deviation exceeds the threshold value; entering (123) said selected updated correction value into a second characteristic map for correction values assigned to the selected operating points of the internal combustion engine and using said selected updated correction value to control the controlled variable (132) for a subsequent non-steady operating state of the drive component at its assigned selected operating point wherein a new selected updated correction value is entered for each occurrence of a subsequent non-steady operating state having a deviation exceeding the threshold value; interpolating selected set values received from said memory means (91) for selected operating points neighboring a non-selected operating point in a second arithmetic means (66) to obtain a non-selected set value (t set (ZW)) (25) for a non-steady operating state occurring at the non-selected operating point; interpolating selected correction values received from a second memory means (90) for selected operating points neighboring the non-selected operating point in a third arithmetic means (92) to obtain a non-selected instantaneous correction value (K ZW ) (122) for the non-steady operating state occurring at the non-selected operating point; controlling said controlled variable (122) with said non-selected instantaneous correction value; comparing said non-selected set value (t set (ZW)) with the actual value in a second comparison means (93) and determining whether any deviation exceeds the threshold value; calculating a theoretical new correction value (K new (ZW)) in a fourth arithmetic means (97) for the non-selected operating point when the deviation exceeds the threshold value; calculating a transferred correction value (K new (u)) in a transfer stage means (98) from the theoretical new correction value (K new (ZW)) taking into account positional deviation of the non-selected operating point relative to the neighboring selective operating points; entering in the second characteristic map said transferred correction value (K new (u)) at one of said neighboring selected operating points; and employing the selected updated correction value and the non-selected instantaneous correction value for controlling the drive component of the motor vehicle.
