Active steering system of railway vehicles has proven its ability to bridge the gap between stability and curve friendliness. Generally scaled railway vehicles were developed to reproduce the fundamental dynamic behavior of the full size railway vehicle in laboratory conditions. This paper describes the design of the braking/traction control systems as a part of a 1/5 scaled railway vehicle for...

A new type of holonomic omnidirectionul vehicle which consists of wheel mechanisms without free rollers but with conventional tires is presented. We first present a concept of the new driving wheel mechanism with a tire in the conventional style such QS a rubber tire or a pneumatic tire,"Offset Steered Driving Wheel". The configuration of the wheel has an offset distance between a wheel axle an...

This paper discusses the maneuvering control algorithm based on all-wheel independent driving and steering control techniques for special purpose 6WD/WS vehicles. The maneuvering control algorithms considering superior dynamic characteristics of high power in-wheel motors and independent steering system are designed to perform driving and steering control, vehicle stability control, and fault t...

Obesity increases the risks to motor vehicle occupants of some types of injury in crashes. The effects of obesity on injury causation are not well understood and current prevention efforts do not effectively address the increased vulnerability of individuals with high body mass index (BMI). Proximity to the steering wheel has been associated with increased risk due to airbag deployment, and the...

Nowadays, the every vehicle existed mostly still using the two wheel steering system to control the movement of the vehicle whether it is front wheel drive, rear wheel drive or all wheel drive. But due to the awareness of safety, four wheel steering vehicles are being used increasingly due to high performance and stability that they bring to the vehicles. In this report, the performance of four...

STUDY OBJECTIVE We assess the relationship between steering wheel deformity and serious thoracic or abdominal injury among drivers and front seat passengers involved in motor vehicle crashes, while adjusting for important crash factors. METHODS This was a national population-based cohort of adults involved in motor vehicle crashes from 1995 to 2002 and included in the National Automotive Samp...

abstract: in this work, an optimal control scheme with adaptive weighting coefficients is presented which coordinates different vehicle dynamics control objectives, thus ruling out possible conflicts among them. in a new approach, the weighting coefficients in optimal control are adjusted according to the vehicle state in the phase plane in such a way that a priority is given to each objective ...

This study investigated the human fatigue caused by automobile steering wheel vibration. Discomfort data was collected from 15 subjects using a steering wheel vibration bench. A rigid wheel was used to apply sinusoidal rotational excitation of 0.08 m/s and 0.1 m/s amplitude at test frequencies of 4, 8, 16 and 32 Hz. Human discomfort was quantified after periods of 1, 5 and 10 minutes by means o...
