We present experimental results for an active control Intersection Collision Avoidance (ICA) system implemented on modified Lexus IS250 test vehicles. The system utilizes vehicle-to-vehicle (V2V) Dedicated Short-Range Communications (DSRC) to share safety critical state information, allowing for distributed implementation of our provably safe algorithms. Safety is achieved in potential collisio...

This paper reports on research related to avoiding collisions in construction sites using differential GPS technology. In this project, the researchers developed and implemented a system where GPS technology was used in tracking a single vehicle and relaying its information to a central server. Using another simulated vehicle, the server evaluated collision scenarios and sent cautionary message...

PURPOSE This study aims to explore the biomechanical mechanism of lower limb injuries to the driver by establishing a finite element (FE) simulation model of collisions. METHODS First a minibus FE model was integrated with a seat belt system. Then it was used to rebuild two collisions together with the total human model for safety (THUMS) provided by Toyota Motor Corporation: a rear-end colli...

This paper deals with formation control strategies based on Virtual Structure (VS) for multi-vehicle systems. We propose several control laws for networked multi-nonholonomic vehicle systems in order to achieve VS consensus, VS Flocking and VS Flocking with collision avoidance. First, Virtual Vehicle for the feedback linearization is considered, and we propose VS consensus and Flocking control ...

Vehicle technology has increased rapidly in recent years, particularly in relation to braking system and sensing system. In parallel to the development of braking technologies, sensors have been developed that are capable of detecting physical obstacles, other vehicles or pedestrians around the vehicle. This development prevents accidents of vehicles using Stereo Multi-Purpose cameras, Automate...

This article reports the development of an unmanned aerial vehicle capable of attitude estimation and stabilization through the implementation of a nonlinear complementary filter and proportional-integral rate controllers. Four infra-red sensors and an ultrasonic sensor are integrated with the main platform for the collision avoidance schemes and for altitude control, respectively. Critical mis...

In Canada, motor vehicle collisions with wildlife pose an ongoing concern. Canada’s landscape is abundant with national and provincial parks, and many of the highways and roads are surrounded by open wilderness. These areas are frequented by unpredictable animal crossings. Moose–vehicle collisions cause a characteristic pattern of head and neck injuries; ocular injuries may be part of the spect...

In this paper we present the concept for reliable vehicle-autarkic collision detection developed for a Rail Collision Avoidance System (RCAS) that is based on direct train-to-train communication. Similar to existing systems in air and maritime transport, the RCAS approach allows vehicle-autarkic detection of imminent collisions. Designed as a safety overlay system, it shall warn and advise trai...
