This paper presents a hydraulic hybrid vehicle drive train to improve the fuel efficiency of a passenger car. The developed hydro-mechanical drive train enables independent control of the torque at each wheel. The motivation for developing this drive train is a hydraulic hybrid vehicle test bed for the Center for Compact and Efficient Fluid Power at the University of Minnesota. The hydro-mechan...

How should a vehicle he driven to minimise fuel consumption? In this paper we consider the case where a train is to be driven along a straight, level track, but where speed limits may apply over parts of the track. The journey is to be completed within a specified time using as little fuel as possible. For a journey without speed limits, the optimal driving strategy typically requires full powe...

We examined older adults' self-regulation within the region of proximal learning (RPL) framework. Younger and older drivers completed four circuits of increasing difficulty in a driving simulator and were then given a limited amount of time to train for a test. Although older drivers chose to train on easier circuits than younger ones, both age groups focused on the easier circuits first, only ...

Human factors research has played an important role in reducing the incidents of vehicle-train collisions at rail grade crossings over the past 30 years. With the growing popularity of in-vehicle infotainment systems and GPS devices, new opportunities arise to cost-efficiently and effectively alert drivers of railroad crossings and to promote safer driving habits. To best utilize this in-vehicl...

Fatigue is a serious issue for the rail industry, increasing inefficiency and accident risk. The performance of 20 train drivers in a rail simulator was investigated at low, moderate and high fatigue levels. Psychomotor vigilance (PVT), self-rated performance and subjective alertness were also assessed. Alertness, PVT reaction times, extreme speed violations (>25% above the limit) and penalty b...

This paper investigates the effectiveness of using CVT (Continuous Variable Transmission) in Samand automobile.  For this analysis, the conventional Samand and a Samand equipted with CVT are modeled and simulated by using Simulink based software (ADVISOR) and the performances are compared.  This analysis includes the effect of driving cycle, fuel consumption and the efficiency of components of ...
