When measuring the power or torque of a vehicle the velocity or speed of the vehicle while driving on a road and accelarating in a certain gear is recorded at certain time intervals or time increments, and on the basis of the velocities recorded during accelaration the change during the said time interval or time increment in the kinetic energy of the vehicle during acceleration is determined, whereafter the change in power during acceleration in the said time interval or time increment is determined. Correspondingly, the velocity of the vehicle while driving on a road and decellerating in the same gear as when accelerating, or possibly declutched, is recorded at certain time intervals or increments, and on the basis of the velocities recorded during deceleration the change in the kinetic energy of the vehicle during deceleration in the said time interval or time increment is determined, whereafter the change in power during deceleration in the said time interval or time increment is determined. Subtraction of the change in power during deceleration from the change in power during acceleration provides a measure of power representing the power of the vehicle without loss in the transmission of the vehicle, and a subsequent conversion of the measure of power optionally provides a measure of torque. |
