In-vehicle weight in motion system

Svitek M., Pejsa L., Kadlecek B.

Zeszyty Naukowe. Transport / Politechnika Śląska

2004

z. 55

409-415

The paper deals with the current research and development results in area of weight in motion systems using the processing of in-vehicle data together with other measured data like acceleration, whether condition, etc. The described data processing results in the determination of vehicle weight that can be used for weight in motion applications (overloaded vehicles on roads and highways), evaluation of public transport line occupancy, etc.

Referat opisuje bieżące badania i wyniki opracowań w obszarze ciężaru w systemach ruchomych wykorzystując dane pojazdowe wraz z innymi danymi zmierzonymi takimi jak przyspieszenie, warunki pogodowe itp. Przetwarzanie opisywanych danych pozwala na określenie wartości ciężaru pojazdu, jaki może być użyty jako ciężar w zastosowaniach ruchowych (przeciążone pojazdy na drogach i autostradach), oceny zajętości publicznych linii transportowych itp.

Virtual Vehicle-Driving cycle application for measuring emission and fuel consumption on HDVS

This proposed methodology is a simple, cost-effective and user friendly alternative to the ECE R83.03. It is suitable/or basic measurements and vehicle diagnostic applications in service centers measurements. The methodology makes use of the quasi-static method. Measurements are carried out without the use of the Power Absorption Dynamometer. A narrow rotational frequency range is measured at a given time, and builds on gradually to successive measurements. Power is not transmitted through the driving wheels. For adhesion, it is not necessary to load the vehicle and the method can be suitably applied to HDV measuring. Test results are registered in grams of emission and fuel consumption per distance traveled in conformity with random loading of a defined driving cycle. The driving cycle is realized in a virtual way by measurements arrived at in the field of variables. Precision of the measurements depends on the sensor used and is comparable to the precision of the measurements made on chassis dynamometer.
