V2V Wireless Communication Protocol for Rear-end Collision Avoidance on Highways with Stringent Propagation Delay

Influence of wireless communication transport latencies and dropped packages on vehicle stability with an offsite steering controller

“…Propagation delay is the time taken for information to travel across a channel, in VANETs this is the air between the transmitter and the receiver. Fortunately, its effect is largely negligible unless the distances between nodes reach more than a few kilometres [24]. Transmission delay is the time taken to put a packet of information on a channel and is a function of the packet size and the bit‐rate of the transmitter.…”

Corona segmentation for nighttime brake light detection

“…where NH i and NV j represent cumulative value for columns and rows, respectively. Even though (8) and 9 Beside utilising a static threshold and cumulating the differences, a dynamic threshold is processed after filtering. Initially, maximum…”

“…In addition to industrial developments which are mostly implemented to the vehicles, large number of researches have been made regarding rear-end collision warning and avoidance systems in the past decade [2][3][4][5][6][7][8][9][10][11][12][13][14]. These papers address a wide range of methods and sensors, however, what we put forth is a novel approach using corona segmentation for discriminating brake lights from other lights for night cruising with a single camera.…”

An Intelligent System to Avoid Collision in Vehicle based on Can Protocol

“…The controller evaluates this data and calculates the acceleration/deceleration of the vehicle ahead. Also an accelerometer to monitor the acceleration and deceleration of his vehicle is installed [8]. Thus the data from Ultrasonic sensor and the on board accelerometer are evaluated and compared and based on this warning messages are sent to the driver.…”
