Claim Text:
1. A computer-implemented method for controlling a drive unit of a vehicle, comprising: determining a mass of the vehicle after each standstill, when a first acceleration occurs; determining, by a processor, a first acceleration variable, which is determined at least from an operating state of the drive unit, receiving, by the processor, a second acceleration variable which is sensed by an acceleration sensor, wherein the second acceleration variable includes a first component, in a direction of a vehicle longitudinal axis, and a second component, perpendicular to the vehicle longitudinal axis; comparing, by the processor, the first acceleration variable with the second acceleration variable; determining a difference between a desired acceleration, which determined based on an ascertained force and the mass, and a measured acceleration; detecting, by the processor, an error if the difference is greater than an applied threshold; and controlling, by the processor, metering of fuel to an internal combustion engine of the vehicle, taking into consideration the detected error; wherein the first acceleration variable is determined as a function of the second component of the second acceleration variable, the error is detected if a value of the second acceleration variable deviates from a value of the first acceleration variable, and at least one of (a) at least one variable characterizing an injected fuel quantity and (b) the second acceleration variable is taken into consideration as the operating state of the drive unit.
