TL;DR: The work proposes a mechanism that not only computes the deceleration of vehicle due to braking and displays the brakingintensity through an array of LED but also involves monitoring the braking intensity levels and communicate it to the vehicles that are following it in lambertian range of IR transmitter module to avoid any collision pre-hand.
Abstract: Driver and passenger safety is one of the prime concerns in modern day vehicle. Alarming statistics of accidents and increased number of vehicles on road demands for an intelligent safety mechanism that helps the driver in handling immediate precarious situations like sudden probability of a rear- end collision. The work proposes a mechanism that not only computes the deceleration of vehicle due to braking and displays the braking intensity through an array of LED but also involves monitoring the braking intensity levels and communicate it to the vehicles that are following it in lambertian range of IR transmitter module to avoid any collision pre-hand, due to any situation that may arise and cause immediate deceleration of the vehicle ahead. An ARM Cortex MO microcontroller will be interfaced with an accelerometer that senses the deceleration levels, a LED array to display the braking intensity and an IR transceiver module for inter-vehicle communication that would transmit pulses whose frequency is modulated proportional to the braking intensity level. To take decision and automatically control the motion of the following vehicle, a collision avoidance system consisting of CortexMO microcontroller is implemented that warns the drier using a buzzer and messages the active and passive safety mechanisms to be activated using CAN protocol and takes control decisions according to an algorithm designed to handle the situation.

TL;DR: A novel methodology, which monitors in real time the traffic scenario behind the driver of a motorcycle and also an intimation system to inform him about the same and an accurate algorithm used in conjunction are presented.
Abstract: The past few years have shown an exponential rise in the total number of people commuting with their own personal vehicles. An increase in vehicles has also statistically led to an increase in the number of road accidents as well. Though a lot has been worked upon with respect to the safety of cars, very little has been done to protect the drivers of two wheelers. In this paper we present a novel methodology, which monitors in real time the traffic scenario behind the driver of a motorcycle and also an intimation system to inform him about the same. A cost effective setup and an accurate algorithm used in conjunction have also been elaborated. Special cases such as giving priority during turning have also been highlighted. All algorithms were designed and developed using MATLAB 2011b and a Spartan 3E FPGA was utilized to assist in simulating a real time environment.

TL;DR: The development of vehicle speed controlled driving system for a semi-autonomous vehicle to reduce or avoid emergency conditions while improving the driver-vehicle interface is presented.
Abstract: Automotive electronics is developing a standard in vehicles. In-vehicle networking is used in control circuits to increase vehicle safety and reliability to ensure intelligent control with high performance. This paper presents the development of vehicle speed controlled driving system for a semi-autonomous vehicle to reduce or avoid emergency conditions while improving the driver-vehicle interface. In-vehicle networking works with different protocols which is a method for communicating data among distributed electronic modules via a serial data bus. CAN is a vehicle bus used for communication between microcontrollers without host computer. This system will analyze and introduce monitoring and controlling automatic headlight, vehicle speed control with obstacle detection, temperature, seat-belt and battery voltage to handle an emergency situation through two nodes which are communicating through CAN protocol. These nodes monitoring and controlling above parameters by communicating with each other.

Abstract: The most of the people using vehicles which have become the most important part in our life for transportation. In existing system the main snags are glaring effect accidents due to opposite vehicle headlight illumination at night driving. Second the short circuit fault in automotive wiring. Third is to perceive gas leakage fire accidents. Fourth faults due to increase in temperature on engine. Fifth higher sound in horn which cause disturbance in restricted surroundings. Sixth inaccurate fuel level monitoring in analog meter. Seventh accidents due to unequal wheel pressure. The proposed system has two modules Master and Slave they are communicating through CAN (Controller Area Network). The hardware has been developed in SMT (Surface Mount Technology) with SMD (Surface Mount Device) components and the hardware uses double layer PCB (Printed Circuit Board) design to optimize the space requirement and power consumption. The proposed system will be in cost effective safety system, reliability and hardware size will be small.

TL;DR: A new approach for the calculation of the trigger time of an emergency brake that simultaneously considers all physically possible trajectories of the object and host vehicle and the orientation of the vehicles is incorporated into the collision estimation.
Abstract: The autonomous emergency brake (AEB) is an active safety function for vehicles which aims to reduce the severity of a collision. An AEB performs a full brake when an accident becomes unavoidable. Even if this system cannot, in general, avoid the accident, it reduces the energy of the crash impact and is therefore referred to as a collision mitigation system. A new approach for the calculation of the trigger time of an emergency brake will be presented. The algorithm simultaneously considers all physically possible trajectories of the object and host vehicle. It can be applied to all different scenarios including rear-end collisions, collisions at intersections, and collisions with oncoming vehicles. Thus, 63% of possible accidents are addressed. The approach accounts for the object and host vehicles' dimensions. Unlike previous work, the orientation of the vehicles is incorporated into the collision estimation.

TL;DR: A novel vehicle detection algorithm based on existing head- and taillight detection algorithms for Adaptive Headlamp Control (AHC) is presented and proves to be robust in various near-collision situations.
Abstract: Forward Collision Warning (FCW) together with Lane Departure Warning (LDW) and Electronic Stability Control (ESC) can highly contribute to a safer traffic environment. Therefore those three systems will be supported by the US NCAP (New Car Assessment Program) until the end of 2009 and rewarded in the new active safety rating. LDW and ESC are already on the market whereas development on the first vision-based FCW systems is still ongoing and enforced. This paper will give a short overview on common approaches in vehicle recognition and focus on nighttime conditions. Based on existing head- and taillight detection algorithms for Adaptive Headlamp Control (AHC) a novel vehicle detection algorithm is presented. The main challenge hereby is the accurate pairing of detected vehicle spots. The developed system also contains rough distance estimation and a robust Time-To-Collision (TTC) calculation. Sequences in various traffic conditions with hand-labeled vehicles serve as an evaluation set for the vehicle detection performance. Ground truth for TTC is available by radar sensor data. The system proves to be robust in various near-collision situations.

TL;DR: This V2V wireless communication protocol provides a realistic simulation in Ns-2 for various topologies and the performances were evaluated for different parameters such as EWM delay, delay due to overhead packets and probability of successful delivery of the emergency warning message (EWM).
Abstract: More than 23% of annual vehicle accidents are rear-end collisions, this gives an important test-case for enhanced collision avoidance approaches based on v2v wireless communications. V2V wireless network concern with the impact of a IEEE 802.11 based multi-hop MAC protocol that propagates an emergency warning message (EWM) down a platoon of cars on a highway. The design objective is to ensure reception of this message with stringent delay constraints so as to provide drivers with requisite available manoeuvre time (AMT) to avoid rear-end collision. This V2V wireless communication protocol provides a realistic simulation in Ns-2 for various topologies (lane-1& lane-3) and the performances were evaluated for different parameters such as EWM delay, delay due to overhead packets and probability of successful delivery of the emergency warning message (EWM).
