Current internal combustion engine technology for road vehicles allows us to meet the existing and planned future standards for emission. However, the motion of a moving vehicle used in real operating conditions is frequent changes of the values of power in the powertrain. The analysis of the results of the road test through a measurement of parameters of engine in a passenger car proves, that the changes of parameters engine are frequent. The paper presents method measurement parameters form system of data transmission CAN BUS and estimation is performed using measurement accelerometer car's chassis of parameters internal combustion engine determined on road test. Estimation of main parameters of internal combustion engine is made with use of measured quantities such as: car mass and acceleration collected in function of vehicle linear velocity. The most essential problems in this approach, considered as primary method errors, are minimization of underestimation of moment of inertia of rotating elements in drivetrain and efficiency of drivetrain itself. Moreover it is vital to determine as precise as possible vehicle acceleration and its linear velocity in presence of disturbances - mainly chassis movements and additional accelerations, which comes from pavement unevenness (roughness). In this article application of several sensors of different quantities for increase of accuracy of PAAF 2 (Power Acceleration And Force) device in relation to prototype device predecessor is taken into consideration.
