Abstract

The motor is started and warmed up to working temperature, then torque values of the motor produced at different rpm values are determined during varying the load of the motor. According to the present invention, determining the torque values produced by the motor is accomplished during operation of the motor vehicle by means of measuring of deformation of a statically rigid part - preferably frame, frame element (2), motor sustaining element, carrying system, pivoting arm, half shaft - of the motor vehicle. Measuring of deformations is preferably made by using a strain gauge (4). An apparatus having a means for measuring the torque delivered by the motor and in given cases a means for measuring the rpm value of the motor is employed. According to the present invention the means for measuring the torque delivered by the motor is an element appropriate to measure deformations suffered by a statically rigid part - preferably frame extension (2), motor sustaining element, pivoting arm, half shaft - of the motor vehicle, expediently a strain gauge (4) and/or a piezoresistive element fastened onto the said statically rigid part.
