Samenvatting
Some new advanced driver assistance system (ADAS) applications need in-the-lane vehicle positioning. For this reason, the combined use of global positioning system (GPS) and inertial measurement systems is proposed. In some areas GPS signal is lost, so it is necessary to know the positioning error when using only inertial system data. Results show that it is better to correct GPS positioning when its signal is degraded than to wait until signal is definitively lost. Some results have been checked using uncertainty propagation law. Furthermore, inertial measurement systems and GPS receivers of different accuracy levels have been compared in order to determine if they are suitable for new ADAS applications.
