In this paper, for the purpose of improving the ride comfort of a passenger car, the use of an air-cell on top of the conventional polyurethane foam seat is proposed. The air-cell can be modeled as a variable spring with the change of its internal air pressure. Therefore, for different human sizes and road disturbances, the adjustment of the air-cell can make the optimal contact pressure betwee...

Crash data from two UK resources were examined for differences between male and female passenger car drivers in collision circumstances and injury outcomes. The proportion of female car license holders is growing, women are more likely to be the driver in a collision and are more vulnerable to injury particularly neck strain. Women drive smaller, lighter cars compared to men and are more often ...

Project summary This technical report is one of a series (listed in full below). Together these reports describe a complete hardware-in-the-loop (HIL) simulation that reproduces the behaviour of a passenger car travelling down a motorway. In the simulation, the speed and position of the car are determined by an adaptive cruise control system implemented using one or more embedded microcontrolle...

Vehicular connectivity can be fairly considered a future killer application, adding extra value to the car industry and operator’s services. Its main feature is to provide car safety and passenger comfort. Thus the issue of content distribution for these emerging vehicular applications needs to be handled carefully. In this paper we have done comparative study of different systems that can be u...

In a modern small sized passenger car fitted with a common rail diesel engine, turbo-lag is an important factor which hampers its performance. This paper discusses the basics of turbo-charger and VGT and some of the methods employed to reduce the turbo-lag in CRDI diesel engine. A novel turbocharger concept, approach to design, the control strategy and advantages of the concept are explained.

Electric vehicles are considered as technology which can significantly reduce the problems related to road transport such as increasing GHG emissions, air pollutions and energy import dependency. The core objective of this paper is to analyze the current energetic, ecological and economic characteristics of different types of electric vehicles. The major conclusions of this analysis are: The hi...

OBJECTIVE We sought to determine the age at which US parents first turned their child's car seat to face forward and information sources used to make that decision at the time of the release of the 2011 guidelines for child passenger safety and 30 months later. METHODS We administered 2 separate cross-sectional Web-based surveys of nationally representative panels of US parents in May 2011 an...

This paper deals with the problem of dynamic modelling and identification of passenger cars. It presents a new method which is based on robotics techniques for modelling and description of tree structured multi-body systems. This method enables us to systematically obtain the dynamic identification model, which is linear with respect to the dynamic parameters. The estimation of the parameters i...
