The invention relates to a method and a device for controlling the drive unit of a vehicle. According to said method, an error is identified from the comparison of a first acceleration variable (AW), which is calculated at least from the operating state of the drive unit, with a second acceleration variable (A). The second acceleration variable (A) comprises a first component (A1) that runs in the direction of the longitudinal axis of the vehicle and a second component (A2) that runs perpendicular to the longitudinal axis of the vehicle.
