This document presents the results of the TEGA AP 3500 "Experimentelle Validierung 'Fahrzeugdynamik'". In the first section, the evaluation strategy is presented. Based on the strategy, the experimental setup both for test drives and the laboratory are derived as it is feasible to compare real life measurement data with simulated vehicle data. A test vehicle is equipped with measurement equipment for allowing both capturing a reference trajectory and the sensor measurements. The laboratory setup then generates the simulated GNSS signal and the vehicle measurements derived from the reference trajectory. The analysis of the gathered data is conducted in post process using an analysis tool written in Matlab. The recorded data from the reference system and the vehicle sensor data are preprocessed. Corresponding to the vehicle's position and velocity a second data set containing the sensor measurements is recorded and processed. The evaluation process then consists of the comparison of the simulated and real life vehicle sensor measurements at every time stamp both values exist. The differences between them are evaluated, e.g. concerning scattering or systematic offsets. Several test drives have been evaluated in the region of Braunschweig. Different environments such as rural roads and highways have been chosen for evaluation. The evaluation of the sensor data in all scenarios shows positive results. It can be observed, that the simulated and the real measurement values are virtually congruent. No significant outliers are visible in the scenarios. Hardly any measurements with an offset larger than 1 m/s are present. A distinct zero-mean Gaussian distribution occurs with a small variance. The average offsets are in the order of 10-3 m/s. The standard deviation values are 10-2 ... 10-1 m/s. It can be concluded that a realistic simulation is granted by the implemented system.
