Use of GPS and CAD in Vehicle Dynamics Study

Most activities involved in vehicle design and development are based on CAD software, that are not just drawing and modeling tools, but also include analysis and programming features. The analysis of vehicle behaviour involves dynamic data acquisition, and a modern method consists in using GPS devices. This study propose some solutions like: an original data acquisition system based on GPS, hardware and software; a CAD application for GPS data processing, used to import and process data; applications for vehicle's dynamic behaviour estimation, using the presented devices and methods: coast-down tests, acceleration and braking tests; applications for analysis of vehicle's speed in urban traffic, using GPS devices and CAD software; an urban driving cycle proposed for Brasov city; a method, including a CAD software library, to analyse the influence of the vehicle's speed on the road traffic noise.
