Automated Vehicles aim to increase road safety as automated driving systems (ADS) take over the human driving task in the operational design domain (ODD), introducing severe challenges for safety validation. Pure driving over many kilometres to gather enough evidence for a safety argument is not feasible. Scenario-based testing is an approach to ov...

To effectively fight against traffic accidents, it is of great importance to analyse and understand the conditions that are linked with accidents. Such an analysis can serve as the basis to (i) develop reactive measures by finding the links between the pre-accident conditions (ii) devise proactive strategies that will prevent the occurrence of acci...

Increased safety is one of the main motivations for traffic research and planning. The arduous task has two components: (i) improving the existing traffic policies based on a good understanding of risk factors related to trends in traffic accidents, and (ii) underpinning the emerging technologies that will advance the safety of vehicles. For the la...

Increased safety has been advocated as one of the major benefits of the introduction of Automated Driving Systems (ADSs). Incorporation of ADSs in vehicles mean that associated software has safety critical application, thus requiring exhaustive testing. To prove ADSs are safer than human drivers, some work has suggested that they will need to be dr...

The unprecedented COVID-19 pandemic has affected most aspects of human life, including the ways in which organizations are operating. Minimizing the spread of coronavirus and its economic consequences, and creating a new and safe lifestyle has now become the common goals of governments all over the world. Although governments have responded to the...

For the appropriate design of Advanced Driver Assistance Systems (ADAS) and Automated Driving (AD) systems, it is important to understand the process of driver-automation interaction and the factors affecting this interaction. In order to develop a part of this understanding, an exploratory driving simulator study with fifteen participants was cond...

There has been an increasing focus on the development of automation in vehicles due its many potential benefits like safety, improved traffic efficiency, reduced emissions etc. One of the key factors influencing public acceptance of automated vehicle technologies is their level of trust. Development of trust is a dynamic process and needs to be cal...

There is a growing interest by the public, policy makers and technologists in vehicles having highly automated systems, and ultimately autonomy. However, there is an apparent gap between where the automotive industry wants to go, and where its approach to safety assurance has come from, e.g. where the human driver is often treated as a primary risk...

Hazard Analysis and Risk Assessment (HARA) in various domains like automotive, aviation, and process industry suffers from the issues of validity and reliability. While there has been an increasing appreciation of this subject, there have been limited approaches to overcome these issues. In the automotive domain, HARA is influenced by the ISO 26262...

While accident data show that human error is the cause of most of the on-road accidents, the move towards assisting or replacing the human driver with an automated system is not a straightforward one. Industries like aerospace, manufacturing, process etc. have a high penetration of automated systems; however, the automotive industry provides new ch...

This paper presents first step towards the development of a simulator based research facility designed to accommodate simultaneous emulation and characterisation of over-the-air and in-vehicle communication channels. The case study demonstrates a unique capability to emulate over-the-air GPS satellite signals in real-time with the ability to contro...

Recently there has been a growth in the incorporation of autonomous features within vehicles. From being perceived as a comfort feature, autonomous features in vehicles have now become a safety feature which are foreseen to reduce accidents. This has led to a new trend within the automotive industry of focussing on autonomous features for driver sa...

This paper gives an overview of the new Drive-in Driver-in-Loop simulator at WMG, University of Warwick, UK, which has been conceptualized to serve as a standard platform for virtual verification and validation of autonomous features. This front loading approach is key to the development of some of the upcoming technologies which have been lagging...

Regenerative braking is one of the most important features of a hybrid vehicle. Currently used regenerative braking systems add a considerable cost to the vehicle due to the electronics involved. The author presents here a novel method for implementing a regenerative brake strategy without changing the mechanical brake system, i.e., without adding...

Regenerative braking has become one of the major features for a hybrid vehicle as it converts brake energy into electrical energy storable into battery and leads to an increase in overall fuel efficiency of the vehicle. Traditional regenerative braking systems are designed such that the mechanical braking force from the friction brakes is varied in...
