A method is for determining the engine reference torque, used in a controller of a motor vehicle, of the engine of the motor vehicle, wherein the engine reference torque is determined by estimation. A value for the mass of the motor vehicle and a motor vehicle velocity value determined at each of two different times during acceleration of the motor vehicle are determined. An engine power of the engine is calculated from these values, and a value for the engine reference torque is estimated via the calculated engine power on the basis of power and torque curves, which are stored as a function of the speed of the engine.
