Comparative study of two dynamics-model-based estimation algorithms for distributed drive electric vehicles

Zhang, Xudong ; Göhlich, Dietmar ; Fu, Chenrui (2017)

The effect of vehicle active safety systems is subject to the accurate knowledge of vehicle states. Therefore, it is of great importance to develop a precise and robust estimation approach so as to deal with nonlinear vehicle dynamics systems. In this paper, a planar vehicle model with a simplified tire model is established first. Two advanced model-based estimation algorithms, an unscented Kal...

Methodische Entwicklung und Bewertung von Elektrifizierungskonzepten für innerstädtische Nutzfahrzeuge

Gräbener, Sven (2017)

Der Einsatz elektrischer und hybridisierter Antriebe ermöglicht die Energieeffizienz von Fahrzeugen zu steigern und gleichzeitig lokale Emissionen zu senken. Insbesondere innerstädtisch tragen schwere Nutzfahrzeuge durch hohe Kraftstoffverbräuche und starke Geräuschentwicklung auf anspruchsvollen Einsatzprofilen besonders zu auftretenden Emissionen bei. Bei Pkw und Linienbussen existieren berei...

A hierarchical estimator development for estimation of tire-road friction coefficient

Zhang, Xudong ; Göhlich, Dietmar (2017-02-08)

The effect of vehicle active safety systems is subject to the friction force arising from the contact of tires and the road surface. Therefore, an adequate knowledge of the tire-road friction coefficient is of great importance to achieve a good performance of these control systems. This paper presents a tire-road friction coefficient estimation method for an advanced vehicle configuration, four...

Integrated traction control strategy for distributed drive electric vehicles with improvement of economy and longitudinal driving stability

Zhang, Xudong ; Göhlich, Dietmar (2017-01-19)

This paper presents an integrated traction control strategy (ITCS) for distributed drive electric vehicles. The purpose of the proposed strategy is to improve vehicle economy and longitudinal driving stability. On high adhesion roads, economy optimization algorithm is applied to maximize motors efficiency by means of the optimized torque distribution. On low adhesion roads, a sliding mode contr...
