Patent ID: 7769500

Claim:
A method for operating a drive unit of a motor vehicle, comprising: determining, by a driveshaft angle sensor, a driveshaft angle of a driveshaft driven by the drive unit; representing, for at least one operating quantity of the drive unit, a deviation from an initial value by an adaptation value, wherein the adaptation value is determined at a plurality of points of time at the determined driveshaft angle; storing, in an extreme value storage unit, a first adaptation value determined at a first point in time; comparing a second adaptation value, determined at a point in time after the first point in time, with the first adaptation value stored in the extreme value storage unit to determine whether the second adaptation value exceeds the first adaptation value in a predetermined direction; and if the second adaptation value exceeds the first adaptation value in the predetermined direction, overwriting the extreme value storage unit with the second adaptation value; and implementing the second adaptation value which exceeds the first adaptation value to operate the drive unit.
