The main objective of this study was the metrological validation of a common data acquisition system, to use in researches with ground vehicles. From the information collected, such as travel speed, longitudinal and lateral acceleration and angular velocity, was performed an analysis of errors and a study of variance, using the equipment in accordance with the existing technical standards. The validation was made by comparison the results of the collected data with the results collected with calibrated equipment, and by applying a procedure of path reconstruction. The motivation of this work is in ensuring the reliability of commercial equipment for use on various issues of interest to the group of Vehicular and Robotics Systems, in the areas of modeling and vehicular testing. This work fits into the context of the use of new technologies for control and monitoring, which are increasingly involved in ground vehicles in order to improve the comfort and safety of its passengers. The methodology used was to equip a vehicle to run with the system MQ200-PRO from MaxQData, perform the collection of key variables associated with its dynamics in different conditions of operation, process the data and use them in the metrological validation of equipment and path reconstruction. Despite the goals have been achieved, the results showed interesting aspects about the differences between processing stationary and dynamic data. In conclusion, it is important to highlight the need of establishment specific rules for employment of such equipment, including criteria not only static or stationary.
